    Triticum aestivum

    Bread Wheat

    Triticum aestivum|Bread Wheat||Triticum aestivum, also known as common wheat or bread wheat, is an annual grass used commonly in the production of the staple food grains. The grains are then made into flour, straw or hay, or sometimes used in the production of alcoholic beverages.  In some cases, Triticum aestivum is considered to be a weed or invasive species.  In the United States, common wheat can be found in every state except for North Dakota.  Common wheat was believed to have originated in 9,000 B.C. from the hybridization of another wheat Triticum urartu and an unknown grass.  Common wheat grows best in fertile, nitrogen-rich soil and does not grow well under heat and humidity.  Tolerant of high pH, drought and disease, the common wheat can grow under less than optimal conditions for most plants.  Common wheat can grow up to four feet tall (1.2 m).  Triticum aestivum is only known in cultivation - the exact origin of the plant is still largely unknown.   As humans evolved from a hunter-gatherer society to an agrarian lifestyle, studies have shown that grains also gained size and the seeds became stronger and less likely to shatter. |E

    Helix aspersa

    Garden Snail

    Helix aspersa|Garden Snail||Also known as garden snail or common brown European snail, Helix aspersa is a smaller pale brown snail from the phylum Mollusca.  The garden snail’s shell is dark brown and round with a spiral towards the center of the shell.  Garden snails are nocturnal and typically do not emerge into the daylight unless it is raining.  Their diets consist largely of plants, fruits, dead animal tissue, and paper products.  Garden snails are considered a pest in many gardens, as they consume most vegetation.  Plants that grow low to the ground are reported to get the most damage, as they are easier for garden snails to get to.  However, height does not deter garden snails from climbing to higher plants in search of food.  Like all snails, the garden snail is hermaphroditic, meaning that one snail has both male and female reproductive organs.  Though garden snails can self-fertilize, they mostly reproduce through mating with another snail.  When two garden snails mate, each snail will produce and lay eggs, which will hatch within two to four weeks. Garden snails can have up to 430 offspring in one year. It takes about two years for a garden snail to mature into an adult.   Garden snails are edible to humans.  Snail farms, which have risen in popularity in Great Britain, are largely successful.  Native to Europe, South Africa and Turkey, garden snails were introduced to the United States and have proliferated there.|E

    Mnemiopsis leidyi

    Warty Comb Jelly

    Mnemiopsis leidyi|Comb Jelly||Mnemiopsis leidyi, also known as sea walnut or comb jellyfish, is a ctenophore that is native to the north and south coasts of the Americas.  The comb jellyfish was accidentally introduced to the Black Sea through ballast water, or water put in ships to make sailing more stable. Since accidental introduction of comb jellyfish to certain areas, it has destroyed local ecosystems and has continued to expand to regions of the Mediterranean. Since the comb jellyfish was introduced to the Black Sea, the region has experienced decreased biological diversity of species and a decrease in biomass, especially for some fish species where their eggs have been eaten by comb jellies. A predator of comb jellyfish as well as an invasive species and ctenophore Beroe ovata was introduced to the Black Sea, where today both the comb jellyfish and Beroe ovata populations have stabilized. The word ctenophore comes from the Latin word “ctena” meaning comb-bearer, referring to the four rows of cilia.  Comb jellyfish are not true jellyfish because they do not have stinging cells, also called nematocysts, which means that comb jellyfish cannot sting.  Rather, they are distantly related to true jellyfish.  Comb jellyfish are nearly transparent and bioluminesce at night if they are disturbed.  They can live in oxygen-poor areas and they are not dangerously affected by pollution. Comb jellyfish are filter-feeders that eat zooplankton, fish eggs and larvae.  Sea nettles are the primary predators of sea jellyfish and keep populations of comb jellyfish in check.  Comb jellyfish are hermaphroditic and can self-fertilize, but under good environmental conditions, comb jellyfish will prefer sexual reproduction and spawn, releasing thousands of eggs into the ocean for external fertilization. Under harsh environmental conditions, comb jellyfish will reproduce asexually.|E

    Sequoiadendron giganteum

    Giant Sequoia

    Sequoiadendron giganteum|Giant Sequoia||Sequoiadendron giganteum, also called giant sequoia, is a coniferous evergreen present in California along the Sierra Nevada.  Giant sequoias have also been planted in parts of Europe.  When fully grown, the giant sequoia can reach heights up to 295 feet (90 meters) and 36 feet wide (11 meters).  The oldest giant sequoia recorded was 3,266 years old.  Giant sequoia seeds can germinate after two years, though they may be able to germinate after a decade.  Today, the conservation status of giant sequoias is listed as vulnerable. Giant sequoia seedlings require bare soil and full sunlight in order to germinate. Since the wood of giant sequoias is very brittle, when giant sequoias are logged, the wood splinters and becomes useless for construction Sequoias require fires to burn the forest floor, which clears material and exposes the bare soil. Only one of three species of the Sequoioideae subfamily to survive the Ice Age, fossils from the Jurassic period suggest that an ancestor of the giant sequoia was present in North America, Greenland, and parts of Europe. After the discovery of the giant sequoia, there was mounting pressure to cut most of these large trees down.  Sequoia National Park, the second national park to ever be created in the United States, was created in 1890 to protect the giant sequoias.  In the 1970s, giant sequoias were used to repopulate areas of Southern California that had been burned.   Today, millions of tourists visit the Sierra Nevada to see witness the beauty and size of giant sequoia trees.|E

    Arabidopsis thaliana

    Thale Cress

    Arabidopsis thaliana|Water-Cress||Arabidopsis thaliana, also known as water-cress or mouse-earred cress, is native to North America, Europe, Asia and Africa. Water-cress is a member of the mustard family, which also includes cabbage and radish. Arabidopsis thaliana is best known for having its five-chromosome genome comprising of approximately 20,000 to 25,000 genes sequenced in the year 2000. Researchers may have used Aribidopsis thaliana for genetic sequencing due to the small size of the plant’s genome, rapid growth, and the plants ability to either self-pollinate or be cross-polinated. The plant is widely used for research in molecular biology and genetics due to the natural variation in Arabidopsis thaliana populations. The earliest record of a water-cress mutation was in 1873. Water-cress can be easily cultivated, and the plant produces seeds frequently. It takes about six weeks for water-cress to grow from seed to germination. About 8 inches tall (20 cm), Arabidopsis thaliana has very small (2-3 mm) white flowers with yellow stamen in the center of the flower and broad leaves at the base of the plant. In many instances, Arabidopsis thaliana is considered a weed. Scientists admire Arabidopsis thaliana for scientific use because of the small number of genes the organism has, as well as the short life cycle of the plant and large amount of seeds that the plant produces.|E

    Opuntia ficus-indica

    Argentine Pricklypear

    Opuntia ficus-indica|Prickly Pear||Opuntia ficus-indica, also known as barbary fig or prickly pear, is a cactus crop that is found in Texas, New Mexico, Arizona, California, Florida, Georgia, Hawaii, North Carolina, the Mediterranean and Puerto Rico.  Plants in the Opuntia family are often referred to as 'succulents' because of their overly-thick leaves and stems which are used to store water. The prickly pear is about 15 feet tall (4.5 meters) and about 10 feet wide (3 meters).  The cactus has large pads about 10 inches long and some spikes.  Yellow or orange flowers grow on these pads and blossom in spring or early summer months.  The prickly pear needs full sun, and if water is scarce, the pads of the prickly pear will shrivel in order to conserve water.  Both the fruit and pads of the prickly pear cactus are edible, and the sweet purple fruit of the prickly pear, also known as 'tunas', is sold in markets worldwide. Some dishes that are made with prickly pear pads include putting the pads in salads, grilling the pads and serving them with eggs, or using the pads for soups.|E

    Crassostrea gigas

    Miyagi Oyster

    Crassostrea gigas|Giant Oyster||Crassostrea gigas, also known as Pacific oyster or giant oyster, is a mollusc native to Southeastern Asia and the marine waters of Japan.  Pacific oysters have been introduced to different areas around the world to be farmed.  They oysters have white shells with some purple streaks.  The inside of the shell is white with no other coloring.  The pacific oyster is very similar to another species under the same genus. Since pacific oysters can attach themselves to any hard surface, it makes it difficult to exclude the species in any aquatic environment.   Pacific oysters will attach themselves to any hard substrate or even to other oysters.  The organisms live in the intertidal zone of the Pacific Ocean.  Pacific oysters can change sex during their lives, usually affected by environmental factors.  Some oysters are hermaphroditic, meaning they have both female and male reproductive organs.  During the breeding season, the reproductive organs of male and female pacific oysters compose about 50 percent of their mass.  Female pacific oysters can produce up to 30 to 40 million eggs per spawning.  The larvae of pacific oysters are free-swimming until they reach a hard surface to grow on.   The two valves that enclose the oyster are unequal in size, with the lower valve being more convex and also In some marine environments, pacific oysters exclude the native marine species by limiting the food supply or available space.|E

  • 66552_88_88 Plantae > Magnoliaceae

    Magnolia grandiflora


    Magnolia grandiflora|Southern Magnoloia||Also called Southern Magnolia or ‘young gem”, Magnolia grandiflora is a perennial native to North America, but is also found in Great Britain where it was introduced in 1734.  The southern magnolia is located in the Midwest to southeastern part of the United States and can grow to be 60 to 80 feet high (18.2 to 24.3 meters).  The southern magnolia has white flowers and red seeds that attract birds and leaves that are elliptical in shape.  The bark of Magnolia grandiflora is smooth and grey in color. The fruit of the southern magnolia is cylindrical in shape with bright red seeds hanging from the fruit. Southern magnolias bloom white flowers about eight to ten inches in diameter (20 to 25 centimeters) in late spring, though the trees typically do not bloom until they have reached seven years of age.  Optimum seed production for the southern magnolia is around age 25. The southern magnolia is also somewhat fire resistant because of a cork layer underneath the bark that is heat resistant. Southern magnolias are commonly used in landscaping both in the United States and in Great Britain because of its beautiful flowers and resistance to fire. It is argued that the best state to grow these trees is Connecticut and Massachusetts.   Magnolia grandiflora grows best in loamy moist soils often found near swamps.|E

    Mus musculus

    House Mouse

    Mus musculus|House Mouse||Mus musculus, also known as the house mouse, is a member of the order Rodentia. Native to Central Asia, the house mouse was accidently introduced to North America through the settlers. House mice live in close association with humans, typically taking up residence in parts of houses and buildings as well as outdoors in fields or amongst crops. House mice weigh about half of an ounce and can be up to 7 inches long, including the 3-4 inch tail. Though nocturnal creatures, house mice can be seen during daylight hours scavenging for food. The incredible reproductive system of house mice can produce up to 13 litters per year, with each litter containing 6 mouse pups. House mice collect scraps of paper or other materials they can get ahold of to create a nest in a sheltered location. Capable of surviving in small areas with limited food and water, house mice have adapted well alongside humans. House mice eat grasses as well as some small insects, as well as glue and soap, but alongside humans, house mice will eat anything that humans eat. House mice are used for biological and scientific experiments because of their fast reproductive systems, especially in mammalian research. House mice can help diseases such as murine typhus, rickettsial pox, tularemia, salmonella, and bubonic plague spread to humans. To prevent house mice from entering human areas, eliminate any holes or gaps in which the mice could squeeze in through. The small size of house mice makes preventative measures fairly difficult. Areas with poor sanitation attract house mice. House mice are capable of surviving in desert and tundra areas that they normally would not be capable of living in without dependency on humans.|E

    Ginkgo biloba


    Ginkgo biloba|Ginkgo||At 150 million years old, the Ginkgo biloba, or Maidenhair tree, is considered to be one of the oldest tree species on Earth. It is debated whether the tree species would exist today without Buddhist monks in Japan and China cultivating ginkgo trees for about 1,000 years. Ginkgo, taken from the Japanese word ginkyo meaning “silver apricot”, describes the small fruit of the tree. The ginkgo tree is also considered a living fossil, meaning fossils of the tree are identical to the living trees today. The ginkgo tree can live for thousands of years. Ginkgo trees that were 1-2 km from the bombing of Hiroshima were one of the few living things to survive the blast. Today, the ginkgo is listed as an endangered species. Typically growing to about 120 feet (36 meters), the ginkgo tree has fan-shaped leaves on long stems, with inconspicuous male or female green and yellow flowers. The leaves of the ginkgo tree turn a bright yellow in the fall. The fruit of the ginkgo tree is round and yellow, with edible gametophytes, or plant organs that produce gametes, in the center of the fruit. The gametophytes of the maidenhair tree are commonly used in Japanese and Chinese dishes. The ginkgo tree is native to China, Japan, Turkey, and Taiwan, though the tree has flourished in regions of North America and Europe since it was introduced in the 1700s. Chinese medicine has used the leaves of the ginkgo tree for thousands of years. Ginkgo extract is the most commonly used in herbal medicine in Europe to increase blood flow, treat allergies, asthma, and bronchitis. Studies have suggested that ginkgo extract increases memory and has positive effects on dementia patients. |E

    Musa acuminata


    Musa acuminata|Plantain||Musa acuminata, also known as the Banana plant or Plantain, is considered an herb and grows to be about 10-20 feet tall after just one year.  There are eight subspecies of Musa acuminate. Banana blossoms ripen into bananas after three to four months.  The trunk of the banana plant is made from sheets of leaves, rather than bark.  This mechanism conserves water, and since banana plants are 90 percent water, it is crucial.  Banana plants are native to India, Southern Asia and Australia, though they have been successfully grown for commercial use in the Americas such as the state of California.  Bananas are the fourth largest fruit crop in the world.   The banana plant is a perennial that prefers moist, well-drained soils and can grow in partial sunlight or full sunlight.  The banana is 12 inches long and 2.5 centimeters wide.  The herb has reddish purple flowers that can either be male or female.  The banana plant flowers year-round.  Trees typically will not produce either fruit or flowers until the second or third year.|E

    Fucus vesiculosus

    Bladder Wrack

    Fucus vesiculosus|Bladder Wrack||Fucus vesiculosus, also known as bladderwrack, is a form of seaweed (or algae) found in the Atlantic, the Pacific and the Baltic Sea. Fucus vesiculosus means “covered in bladders or blisters” in Latin, which refers to the small blister-like sac filled with dioxygen, or O2, which helps the seaweed stay lifted towards the surface of the water. At the base of bladderwrack is a holdfast, or root-like structure which secures the rest of the organism to the floor and keeps it from floating away. The bladderwrack uses photosynthesis to produce its own energy. Bladderwracks also have a chemical called fucoxanthin that makes photosynthesis more efficient by absorbing more sunlight. Bladderwracks have a large amount of predators since it is a primary producer, but over time the organism has evolved mechanisms to keep other organisms from consuming it. The bladderwrack provides organisms such as snails, mussels and small fish shelter. Polysaccharides, or long chains of carbohydrates, prevent the bladderwrack from being damaged by waves or the sun. However, if exposed to sun for too long, the bladderwrack will dry out. Since the bladderwrack is dioecious, each bladderwrack has both male and female parts. Each bladderwrack releases both gametes (eggs or sperm) into the ocean. The gametes will then meet and become fertilized, producing a new bladderwrack. A bladderwrack typically lives for about three years. Although bladderwrack extracts can be used for medicinal purposes, there is still no concrete evidence pointing to its success. Since bladderwrack is from the sea, it contains large amounts of iodine, which is useful for thyroid problems. However, since the amount of iodine in bladderwracks is not constant, it cannot be used effectively. Bladderwrack can also cause severe allergic reactions, and since it comes from the ocean, it may contain arsenic.|E

    Anopheles gambiae

    African Malaria Mosquito

    Anopheles gambiae|African Malaria Mosquito||Anopheles gambiae is a group of seven very closely related species of mosquito that are nearly impossible to distinguish apart from one another.   Female mosquitos are dependent on a source of blood during breeding times, and often rely on a human host to feed from.  Using their sense of smell to detect a host, females become parasitic during only the breeding period. After female mosquitos lay their eggs on the surface of water, the eggs will incubate for a period of 48 hours while breathing underwater.  Then the eggs hatch, with the organisms will then enter a larval stage where they live underwater but breathe oxygen.  Next, after the larval stage comes the pupal stage that lasts for about two days where the pupas do not move or eat as they grow into adult mosquitos.  Once a mosquito has reached adulthood, it is capable of mating immediately.   Anopheles gambiae are yellowish brown in color with a pair of wings and six legs on the thorax.  Male mosquitos have more setae, or bristles, located on their antennae than females.  Males will then use their setae to locate females for mating purposes. Bats, birds, frogs and lizards eat Anopheles gambiae. Some species in the complex Anopheles gambiae prefer water with high salt content while others prefer freshwater for breeding. This complex of mosquito is the largest species responsible for transmitting the lethal malaria parasite (Plasmodium falciparum) to humans.  In the United States where malaria has been irradicated, Anopheles gambiae is largely considered to be just a pest.  However, in Africa, Anopheles gambiae has become a serious problem for humans because of high malaria rates. Even with just breeding females searching for human hosts, a person in Africa may be bitten between 50 to 100 times per night.|E

    Vitis vinifera|Common Grape Vine||Vitis vinifera, also known as the common grape vine, is a deciduous perennial that can grow up to 50 feet tall (15 meters).  The common grape is used for its fruit, which is then sold as is, juice, jelly, or cultivated into various types of wine.  The fruit is round or oval in shape and can range from yellow, green, red, or purple in color depending on the variety. The seeds from grapes can be used to make soap and the oil is used for lighting.  The common grape vine prefers damp woods or riverbanks to grow, and requires a soil pH of about 6.5.  Vitis vinifera produces pale-green sweet-smelling hermaphroditic flowers that bloom from May to July.  Considered to be a European grape, the common grape vine is also widely cultivated in California. Since Vitis vinifera is less resilient to cold than American grape varieties, it is much harder to cultivate in colder regions. Chardonnay is one of the largest varieties of Vitis vinifera cultivated for wine.|E

    Olea europaea|Olive Tree||As the oldest known cultivated tree, olive trees have grown by humans in the Mediterranean for over 5,000 years. Olea Europaea can grow to be 25 to 30 feet tall, producing white hermaphroditic flowers in the spring.  Olive trees can live for over 100 years and begin to produce fruit after six years.  Olive trees grown for their fruit are pruned, which produces more olives per tree.  Olives are used for food and medicine, though the primary product of olives is olive oil, which is sold around the world for various uses.   Though the olive tree is native to Europe, Africa and Asia, it can also be found in California. Extra virgin olive oil is made by cold-pressing the olive seed without the use of chemicals or heat.  It is believed that olive oil reduces circulatory diseases.  Olive seeds are unique because they are the only seed to contain albumin, a water-soluble protein.  The olive oil pressed from olive seeds is suggested to be a medical treatment for a variety of illnesses.  Ancient Greeks used olive branches to crown Olympic game winners. Olive trees have become symbols for peace, wisdom, and victory in many human cultures.|E

    Helianthus annuus

    Common Sunflower

    Helianthus annuus|Common Sunflower||Also known as the common sunflower, Helianthus annuus is derived from the greek words “helios” meaning sun and “anthos” meaning flower.  The common sunflower can range from 1.5 feet to 8 feet tall (0.5-2.4 meters).  Common sunflowers are native to dry, open spaces and require full sun.  They are known for following the sun, starting from the east and by the end of the day, facing the west as the sun sets.  The common sunflower has a large flower with bright yellow petals.  In the center of the flower are thousands of brown flowers called “florets” that bear no petals.  Flowers of the common sunflower bloom between the months of July to October.  The seeds of sunflowers are devoured by many species of wild birds. The seeds, which contain 25-32 percent oil, are used to make sunflower oil.  Sunflower oil is used as frying oil as well as an ingredient in cosmetics. Russia is the world’s largest sunflower oil producer. Sunflowers only live for one season and are considered to be annuals.  The stems of sunflowers have hairy bristles that prevent water loss.  Sunflowers can be found in all 50 states as well as parts of Canada.  Sunflowers are tolerant of both high and low temperatures, and prefer wet, disturbed areas to grow in. Sunflower petals are sometimes used to create yellow dye. Many variants of the common sunflower have been developed through cross-breeding and hybridization.|E

    Corallina officinalis

    Coral Weed

    Corallina officinalis|Coral Weed||The common coral weed, also known as Corallina officinalis, is an underwater plant commonly considered to be a weed. The common coral weed is found in Australia, Japan, South Africa, China, and along the east coast of the United States. This plant prefers to live on rocky shores, and grows abundantly from Connecticut to Maryland along the eastern coast of the United States. Common coral weed grows about 12 centimeters tall and is pinkish white in color, which is caused by the calcium carbonate deposits that give it a white coloring. Common coral weed has branches that are irregular and very stiff to the touch. The fronds of the common coral weed are oppositely branched, and the branches move flexibly through the water. Like other red seaweeds, the reproductive cycle of the common coral weed is very complex. Common coral weed reproduces sexually, with each plant having either male or female reproductive parts, but not both. After the gametes fuse, the cell settles and begins to grow within about 48 hours. After settling on a rough surface, the new plant will grow about 3.6 micrometers per day until it reaches its full growth in about 13 weeks. Though the common coral weed is a common ocean plant species, researchers are unsure how it will handle ocean acidification, which could be detrimental to the species. This plant also provides other ocean organisms a habitat, and even other seaweed species will grow on top of the common coral weed. Sea urchins will eat the common coral weed, but only if their preferred algae is not available for them to graze on. Common coral weed is also a popular ingredient in cosmetics such as eye creams and moisturizers.|E

    Purple Urchin

    Strongylocentrotus purpuratus|Purple Sea Urchin||Strongylocentrotus purpuratus, or purple sea urchins, are invertebrate organisms that live along the coast of the Pacific Ocean from Mexico to Alaska.  Purple sea urchins are members of the phylum Echinodermata, meaning “spiny skin” that encompasses urchins, sea stars, sea cucumbers and sand dollars.  These urchins prefer rocky areas which give the urchins a region to latch on to.  Purple sea urchins feed on forests of giant kelp, and often can expand to an enormous population size and decimate entire forests of kelp.  Sea urchins are also considered pests for kelp farmers because they frequently destroy their crop.  Sea otters, which are the natural predators of purple sea urchins, have purple bones and teeth because of the pigmentation in the spines of the purple sea urchin.  Other predators of the purple sea urchin include sea stars, sunflower stars, and a species of marine fish called California sheephead. Purple sea urchins will attack predatorial sea stars with their pinchers, but will retreat if a sunflower star comes near.  The purple sea urchin is ectothermic, meaning that it relies almost entirely on the temperature of the ocean to maintain its own body temperature.  Purple sea urchins have a protective shell, also known as a test or “skeleton” that is covered by spikes. The mouth, or oral region faces the ocean floor, and the opposite end of the urchin is what would be considered the “top” of the animal. Covering the spikes of the urchin are cilia, tiny hairlike structures that produce a current which moves food towards the urchin and keeps waste from collecting. Typically living to about 20 years, sea urchins become sexually active after 2 years.  Sea urchins usually reproduce between January and March.  Offspring are created through external fertilization where both the male and female parents release their gametes into the ocean. |E

    Duck-billed Platypus

    Ornithorhynchus anatinus|Duck-Billed Platypus||The duck-billed platypus, also known under the scientific name Ornithorhynchus anatinus, is a mammalian species native to freshwater streams in Australia. Ornithorhynchus anatinus came from the Greek meaning “duck-like flat-foot”.  One of the most unique things about the duck-billed platypus is that it lays eggs, making it one of only five mammalian species worldwide with this reproductive method. The other egg-laying mammals are four species of spiny anteaters also called echidna.  The duck-billed platypus has a very sensitive bill with electroreceptors that it uses to hunt for food in the water. Platypuses hunt for food at night and sleep during the day in their burrows built on land.  Platypuses hunt crayfish, insects, tadpoles, and small fish.  The platypus has very strong legs it uses for swimming, as well as webbed feet with claws that help the platypus swim and protect itself.  Male platypuses have a venom gland on the back of their legs that is believed to be used against other males during mating season.  The male platypus venom causes intense pain and is strong enough to kill a dog or seriously injure a human.   The duck-billed platypus is the only remaining living species of platypus.  Platypuses are related to both mammals and reptiles.  For instance, the platypus has splayed legs, which is a feature found distinctly in reptiles, but their bones also can rotate in their sockets, which is a mammalian feature.  Platypuses also have a bone located near the collarbone called an interclavicle that is usually only found in reptiles. Socially, platypuses are solitary animals that hunt alone.  Males do not assist the mother in raising the young, and as soon as the young are able to hunt for themselves, they go out on their own.  Typically living to about 18 years in the wild, platypuses become sexually mature around four years old. Predators of the duck-billed platypus include foxes, crocodiles, as well as large fish and birds.  Humans hunted platypuses until an Australian law was passed in 1912 to protect the species.|E

Also known by the names red wriggler, european earthworm, and common marsh worm, these earthworms are reddish in color with deep purple at the posterior end and can reach up to 150 centimeters in length. Lumbricus rubellus feeds on organic matter and benefits the soil by helping decompose larger soil particles. Like all members of the class Oligochaeta, these worms have about 100 body segments with each segment outfitted with bristles called chaetae to help the earthworm move through the soil. To create tunnels through the soil, Lumbricus rubellus use a type of movement called peristalsis, or a series of contracting and expanding movements. Lumbricus rubellus prefers loose, moist soil with plenty of organic matter to feed upon. Lumbricus rubellus can be seen throughout all months of the year. Also like all other earthworms, Lumbricus rubellus is hermaphroditic, but since the organism cannot self-fertilize, each earthworm still requires a mate to reproduce. The egg sacs of Lumbricus rubellus are drought resistant. It takes about 90 days for Lumbricus rubellus to reach sexual maturity, and typically the number of offspring from each egg sac is very low. Though Lumbricus rubellus contributes to soil health in many areas, the earthworm may carry organisms that can spread pathogens to plants and animals by moving them through the soil. The earthworm can also contribute to removing nitrogen from the soil, which removes an essential nutrient that plants need to grow, as well as assisting with erosion. A rare plant in the great lakes region called a goblin fern, or Botrychium mormo, has decreased significantly in population, with Lumbricus rubellus suspected as the root cause. The decrease in goblin fern populations has lead to legislation being passed in the United States that makes importing Lumbricus rubellus more regulated.|E

    Palmaria palmata


    Palmaria palmata|Dulse||Palmaria palmata is a red algae that also goes by the name of dulse. Commonly found in Europe, North America, Japan and Korea, dulse can be found in colder water temperatures. Named for its resemblance to the palm of a hand and growing in flat blades with “finger-like” extensions, dulse ranges from deep red to purple in color. This red algae is 20 centimeters long and has only one type of chlorophyll, also known as chlorophyll a. Dulse will grow on rocks or even other organisms like mussels or other species of algae. In Northern Ireland, dulse is eaten as a snack, not unlike eating chips. At one time, it was a tradition for the red algae to be harvested and then left to dry out on walls, where it would be consumed afterwards. There is evidence that suggests that dulse has been eaten for centuries, possibly even thousands of years. Dulse is a very nutritional algae that is rich in protein and iron. Considered one of the most delectable forms of seaweed, dulse plants that are closer to the surface are usually considered better in taste. In Northern Ireland, dulse is eaten similar to the way chips are eaten. Dulse can reproduce sexually or asexually. Male plants can produce gametes called spermatia after about nine months, whereas females are fertile after only a few days. Female plants do not release gametes; instead males release spermatia, which land on female plants and become fertilized. The plant is highly intolerant of hydrocarbons and synthetic compounds. Dulse has about 34 times greater concentration of potassium than a banana.|E

    Brown Peatmoss

    Sphagnum fuscum|Brown Peatmoss||Sphagnum fuscum, also known as common brown sphagnum, is a species of peat moss that is native to boreal forests of North America.  This peat moss is typically greenish brown in color, although the small leaves can range from a light green color to light pink.  Sphagnum fuscum does not have flowers, but instead reproduces by one of two ways; Sphagnum fuscum can either release spores that eventually become new organisms, or if a piece of the moss is broken off, the broken piece will become a new organism that is genetically identical to its parent.  Preferring very cold temperatures from around freezing to below freezing, Sphagnum fuscum thrives best in bogs or wetland areas, although it can acclimate to most environments.  This moss grows in clumps, sometimes on the surface of water. These dense clumps may be so thick that they can hold up a large moose.   Since Sphagnum fuscum has large amounts of tubular capillaries that are designed to take in water, the moss can absorb more water than a sponge.  However, if the moss becomes dried out, it is very flammable and is often used as kindling by campers.  In some bog areas, Sphagnum fuscum overtakes the location, depleting its environment of nutrients.  The surface of a layer of Sphagnum fuscum is typically alive and photosynthesizing, but since the underside of the moss cannot access sunlight, the bottom of the moss is dead.   This moss is often used in agriculture; where if placed in the soil, the moss will help surrounding plants retain moisture. Sphagnum moss comprises the highest percentage of coal.  Coal is created when peat mosses become compacted over time, eventually creating coal and other fossil fuels. At one time, this moss was used for its absorbency to make baby diapers and menstrual pads.|E

    Thalassiosira pseudonana

    Thalassiosira pseudonana|T. Pseudonana||Thalassiosira pseudonana is a species of diatom, which is a group of phytoplankton, or algae. This unicellular, round organism lives in marine environments, but may have had freshwater ancestors. Thalassiosira pseudonana was the first diatom to have its genome sequenced, which it was found to have an unusually small amount of genetic material. Researchers hope that by sequencing the genome of Thalassiosira pseudonana, it will be easier to understand the interactions diatoms have with their environments. Thalassiosira pseudonana has had three name changes and is often confused for other species of diatom. Thalassiosira pseudonana has also been cloned, where cultures of the clone are still kept in labs today. Scientists chose to clone this particular species of diatom because the genome was relatively small and less complex than other diatom genomes. Diatoms are one of the smallest and diverse class of Eukaryotes. Diatoms in general are responsible for about 20 percent of the world’s primary productivity, which means that these photosynthetic organisms are responsible for producing much of the world’s food source.|E

    Ulva lactuca

    Sea Lettuce

    Ulva lactuca|Sea Lettuce||Very similar in appearance to lettuce found on land, Ulva lactuca is a six to 24 inch wide alga that grows in flat blades. Also known as sea lettuce, Ulva lactuca grows in flat, strong sheets. Sea lettuce is a vivid green color and grows in both low and high intertidal zones. Sea lettuce, which typically attaches to a substrate via a holdfast, can survive in very choppy waters. However, if a blade of sea lettuce is removed from the holdfast, it is still capable of living and photosynthesizing by free-floating. Sea lettuce requires a large amount of moisture, and if left to dry out, the organism will turn white or black and may not survive. Sea lettuce can be used in place of normal lettuce like in salads. The blades, also known as leaves, are rich in protein, iron, and iodine. To reproduce, sea lettuce first goes through a process of meiosis, or asexual reproduction, where spores are released that eventually become male and female plants. In the second phase, male and female sea lettuce release gametes that when joined develop into a new plant in sexual reproduction. Sea lettuce is a great indicator of pollution, because the more polluted the area, the more sea lettuce there is. Since sea lettuce is an alga, the limiting nutrient that inhibits growth is nitrogen and phosphorus. Through the input of fertilizers and other pollutants that contain an abundance of nitrogen and phosphorus, sea lettuce is free to grow without being limited by lack of these nutrients. Since sea lettuce can live by free-floating on the surface of water, sunlight filtering to deeper regions of the ocean will be blocked by sea lettuce floating on the top. As a result, many plant species located in deeper ocean regions will die off because they cannot photosynthesize without sunlight.|E

    Macrocystis pyrifera

    Giant Kelp

    Macrocystis pyrifera|Giant Kelp||Macrocystis pyrifera, also known as giant kelp, is found in North America along the west coast as well as South America, South Africa, and Australia. Since the plant can grow so tall, giant kelp grows to the water’s surface and shades the ocean floor below, causing growth of algae and aquatic plants to slow in growth because large amounts of sunlight have been blocked off. Giant kelp can grow up to 196 feet (60 meters), and when large amounts are present, underwater ‘forests’ of kelp are formed. The plant grows on rocky surfaces and is anchored there by the plant’s holdfast, a type of root structure. Sometimes, the plant will drift away after intense storms rip the holdfast from the surface it was anchored in. The stipe, or aquatic plant version of a terrestrial plant’s stem, is very flexible and strong. The stipe grows blades that conduct photosynthesis for the kelp. Special cells called trumpet cells transport materials from the very top of the kelp plant all the way down to the holdfast. One of Macrocystis pyrifera’s common predators is the sea urchin, which can devour entire kelp forests. Sea otters, which are the natural predators of sea urchins, will prevent giant kelp forests from being eaten. Giant kelp is often harvested for alginates, which are used as thickeners and as a waterproofing substance. Alginate is derived from the cell walls of brown algae such as Macrocystis pyrifera.|E

    Common Fruit Fly

    Drosophila melanogaster|Common Fruit Fly||Drosophila melanogaster, also known as the common fruit fly, is a 3-millimeter long-winged insect.  Drosophila melanogaster means “black-bellied dew lover” in Latin.  The fruit fly has a lifespan of two weeks; First growing from an egg that hatches within 24 hours, spending three days as a larva, four days as a pupa, and finally molting as an adult.  The mating ritual of the fruit fly begins when a male fruit fly uses his leg to tap the female to sense whether female pheromones are present. If the male detects female pheromones, he will begin to vibrate his wings and “sing”.  “Singing” will make the female more receptive to mating and will spur the other males around the singing male to also begin courtship rituals.  The male fruit fly then mounts the female and will begin mating if the female accepts her mate.   The fruit fly is best known for its use in research, specifically in genetics and behavioral research.  Research on these insects is ideal because of their short life cycle, small size, and small genome.  One of the most prominent experiments done on fruit flies was done by Nobel laureates Edward Lewis, Christiane Nusslein-Volhard, and Eric Wieschaus. Their experiment’s goal was to discover how genes affect embryonic development on complex organisms.  The fruit fly has four pairs of chromosomes containing 14,000 genes.  In comparison, humans have about double that amount at 25,000 genes.  The genome of Drosophila melanogaster has been completely sequenced.|E

    Selaginella lepidophylla

    Rose of Jericho

    Selaginella lepidophylla|Rose of Jericho||Selaginella lepidophylla is a species of plant native to dry desert areas. More commonly known by rose of Jericho, resurrection plant, false rose of Jericho, and dinosaur plant. It should be noted however that another species Anastatica hierochuntica is commonly mistaken for this plant and often the two species share common names. Plants in the genus Selaginella are considered primitive plants. About 400 million years ago, ancestors of Selaginella lepidophylla stood about 100 feet tall. Today, this desert plant is only one foot tall and is green and yellow in color. This plant is found in Texas and Arizona to El Salvador and prefers dry environments with little rainfall. The most unique feature about Selaginella lepidophylla is that when the plant’s environment lacks moisture or rain, Selaginella lepidophylla will curl into a tight ball to preserve moisture, as well as slow all metabolic actions to a near stop. This plant can remain in this state of hibernation for over a year and appears to be dead. Once rainfall begins, the plant will almost immediately begin to uncurl and return to regular metabolic rates. This plant does not produce seeds, flowers, or fruit. Instead, Selaginella lepidophylla reproduces through spores. Selaginella lepidophylla is popular with tourists and is often grown in greenhouses because of its unique ability to “come back from the dead”, hence the name resurrection plant. It is also used frequently in classrooms to study desiccation and rehydration.|E

    Bos taurus|Domestic Cattle||Bos taurus, also known as domesticated cattle or cows, are found throughout most of the world. With the largest population of cattle being in India at 281 million, Bos taurus is derived from the Latin meaning “personal moveable property”.  Domestic cattle have arisen from 80 ancestors 10,500 years ago in parts of Turkey and Iraq.  Since then, the world population of Bos taurus is about 1.3 billion.  Weighing about 600 to 1000 pounds and covered with short hair in black, white, reddish brown, or brown, cows are about 50 inches in height.  Cows also have spot patterns in their hair, with no two cows having the same pattern of spots.  Cows have a 60 degree depth perception compared to the 180 degree depth perception of humans.  They are unable to see the colors red or green.  Typically cows have a lifespan of 20 years and become sexually mature after one year.  Cows are social animals who live in herds for protection.  Cows are able to digest tough material by cutting grass with their bottom teeth and having a stomach with four compartments to break down tough plant material with digestive enzymes. Cattle share 80 percent of their genes with humans.  Cows also share 1000 genes with dogs and rodents, though none of which are found in the human genome. Humans use cows for multiple purposes, including a food source (beef, veal, and dairy products), creation of leather, dung used for fuel and manure, and to perform physical labor.  Male cows, also called bulls, are used in bullfighting and rodeos. Cows can carry Bovine Spongiform Encephalopathy, also called “Mad Cow Disease”, which can be spread to humans through their meat.  Bovine Spongiform Encephalopathy causes degeneration of the brain and is fatal in both cows and humans.  The United States Food and Agriculture Administration says that 18% of greenhouse gas emissions are due to livestock.| E

    Homo sapiens|Human||Originating about 200,000 years ago, Homo sapiens derived from the latin meaning “wise man”. Also known as modern humans, Homo sapiens are closely related to chimpanzees and gorillas. The difference between earlier humans and modern humans is the lighter shape of the skull along with smaller teeth and a lighter jaw. Evolving from archaic humans in East Africa, earlier forms of modern humans are called “anatomically modern Homo sapiens.” Humans can be found in all terrestrial habitats worldwide, including Antarctica. Humans use bipedal locomotion, or walking on two feet, to move around. Humans have very large brains, about 1300 cubic centimeters, which accounts for increased mental abilities. Homo neanderthalensis, also known as neanderthals, are genetically the closest relative to humans and had a brain size slightly larger than the human brain. Humans are typically omnivores; however they also use fungal colonies such as yeast for a food source. Homo sapiens developed agriculture about 10,000 years ago. Humans have a wide variety of mating practices. The gestation period of humans is approximately 40 weeks. One of the most unique attributes of Homo sapiens is behavioral changes that separate them from other primate species, such as broad range of prey and use of tools. Neanderthals are the only species other than humans to display behavior such as marking the graves of their dead.|E

    Chlamydomonas nivalis|Snow Alga||Chlamydomonas nivalis, also known as watermelon snow, is a species of microscopic unicellular algae that thrives in high altitudes over 10,000 feet high. For a long time, it was believed that this organism was actually an oxidized mineral. This fungus is actually red in color because of a carotenoid pigment, but as it grows in the snow, the white and red produce a pink color. Chlamydomonas nivalis loves the cold. Since the organism prefers such high altitudes closer to the sun, higher ultraviolet radiation can damage the thylakoid membrane of chlorophyll, which would be very harmful to the organism. Flavenoids protect the organism from ultraviolet radiation. When Chlamydomonas nivalis germinates, it releases green swimming cells with flagella. These cells will migrate towards the top of the snow, where the swimming cells will lose their flagella, start growing a thick wall and begin to grow colonies of the red algae. During the winter months, this algae lies dormant until the spring and summer months where it will grow blooms. This algae will photosynthesize in the snow.|E

    Bacteroides fragilis|B. Fragilis||Bacteroides fragilis is an anaerobic gram-negative bacteria that can be commonly found in the colon and small intestines of humans and other animals. Bacteroides fragilis is gram-negative and is usually symbiotic with its host. However, if the bacteria leaves the intestines and enters a different part of the body, it can become parasitic and cause an infection. Bacteroides fragilis, when outside the intestines or colon, will begin infecting an area and paralyze leukocytes,which are used by the human body to heal an infection. Bacteroides fragilis makes up about 80 percent of bacterial infections and is curable with antibiotics. The bacteria can also produce enterotoxins, or toxins that target the intestines. Bacteroides fragilis can survive in a variety of environments, and is just as versatile as E. coli bacteria. Bacteroides fragilis produces acetic acid, iso-valeric acid and succinic acid, while competing for nutrients with other bacteria that live in the intestines. Bacteroides fragilis has also been found in patients with meningitis, and can cause abscess formations. Some strains of Bacteroides fragilis are resistant to antibiotics like penicillin. Researchers are studying the genomes of Bacteroides fragilis in order to discover a better antibiotic to treat this bacteria.|B

    Amoeba proteus|Amoeba||Amoeba proteus is a unicellular amoeba that lives in freshwater. Amoeba, meaning change, and proteus, meaning “sea god”. Amoeba proteus moves by using pseudopodia, or false feet. The organism expands and contracts, using its “feet” to move around. Amoeba proteus can sense light and will move away from it. When found in the wild, Amoeba proteus can often be found in the shade underneath lily pads in fresh water. This protozoan is an omnivore and consumes both smaller bacteria and plants. Amoeba proteus reproduces asexually through binary fission, the most common method, encystment, conjugation (where genetic material between two Amoeba proteus is swapped), and regeneration. Though Amoeba proteus is non-pathogenic, other amoebas may be pathogenic. Amoeba proteus can be seen with the naked eye, as it is 3 mm in diameter. Amoeba proteus and another amoeba species, Chaos carolinensis, are often mistaken for one another. The difference between the two is that Chaos carolinensis has multiple nuclei, while Amoeba proteus has only one nucleus. Amoeba proteus consumes its prey by wrapping two pseudopodia around the food source, careful not to touch the organism until there is no possible way for it to escape. Once the food source has been trapped, Amoeba proteus will release digestive enzymes into the enclosed space, effectively digesting it. One of the most interesting things about Amoeba proteus is that it has different eating mechanisms depending on what type of organism its prey is. This fact has led researchers to believe that there may be chemical sensory involved which helps Amoeba proteus locate prey. |E

An asexual organism that has a clear, soft body, Philodina roseola can also be found in soil as well as freshwater. This species falls under the subclass Bdelloidea, which also falls under the common name “Wheeled animacules” due to the strange “revolving” appearance of the corona, or ciliated “crown” the rotifer has. Like all other members of the phylum Rotifera, Philodina roseola do not have a respiratory system or excretory system. There are no males in Philodina roseola, and all the females reproduce new embryos without fertilization. One of the most unique things about this organism is that it can survive extreme temperatures and dryness for several years by creating a cyst. This cyst is pink and encases the entire organism until environmental conditions improve. Philodina roseola has a brain and nerve cords that are connected to the brain. The corona, or “ciliated crown” assists in capturing food. The corona moves the food into the buccal tube, which also typically has cilia, which then moves to the mastax, then the intestines, and waste is released out of the anus. The entire body of Philodina roseola is larger than most Rotifera, usually spanning a body length of no longer than 1 millimeter.|E

What these animals eat and where they live have yet to be discovered, as this organism has never been found in its natural habitat. Trichoplax adhaerens were first discovered in 1883 inside of a laboratory aquarium. The cell body of Trichoplax adhaerens is composed of about 1000 cells with only three cell layers. Its body structure is only made up of four types of cells: cylinder cells that include cilia, gland cells, cover cells located towards the outer region of the organism that also include cilia, and fiber cells that are star-shaped and tend to stretch between the inner and outer layers of the organism. Trichoplax adhaerens is transparent, flat and round. The organism can move around via cilia or by changing its shape. Trichoplax adhaerens will eat Cryptomonas and Chlorella when kept in labs or cultures. The organism has no record of sexual reproduction, but instead will reproduce asexually through binary fission or budding. As only one of two species under the phylum Placozoan, Treptoplax reptans and Treptoplax reptans are considered the “missing link” species that may give more insight to the evolution of animals. The other species under Placozoans, Treptoplax reptans, is speculated to actually be Trichoplax adhaerens. This would technically make T. adhaerens the only species of its phylum. |E

Symptoms of malaria include fever, headache, vomiting, diarrhea, enlargement of the spleen or liver, mild jaundice and nausea.  If a pregnant woman becomes infected by the P. falciparum parasite and it goes untreated, the infection could result in premature birth of the baby.   Plasmodium falciparum residing in the saliva of a mosquito will enter humans when female mosquitoes seek a blood host.  Once inside the human host, the immature Plasmodium falciparum will go straight to the liver, where it will then infect liver cells. After developing into a hepatic schizont, the liver cell will burst and release more of the parasites into the bloodstream.  From there, Plasmodium falciparum will infect red blood cells and consume the insides of the cells.  At stages where large numbers of red blood cells are infected, there will likely be a fever present that can last for up to 48 hours.  The red blood cells of the human host will burst, releasing the parasite where more red blood cells will continue to become infected.  In the two-host life cycle, the mosquito, also known as a vector, will become re-infected with Plasmodium falciparum when taking blood from a vertebrate host such as a human. Plasmodium falciparum is known as an endemic because there is a steady rate of malaria cases in Africa.  Although Plasmodium falciparum is known worldwide, the number of malaria cases is not as high as the ones in Africa.  There is no “true” vaccine for malaria, although the disease can be treated and cured.  In some cases the parasite may be resistant to drugs.  Bed nets are a preventative measure against malaria, as it removes the mosquito vector from transmitting the parasite to a human host.|E

    Tyrannosaurus rex|T. Rex||Tyrannosaurus rex is an extinct species of carnivorous dinosaur from the Late Cretaceous period, about 100 million years ago. Tyrannosaurus rex, meaning “tyrant lizard”, has been found in North America and Asia. Fossils show that Tyrannosaurus rex was 40 feet long and reaching to about 20 feet tall. Barnum Brown discovered fossils from this monumental dinosaur in 1898. The skull of the dinosaur is very lightweight and has about 60 teeth used for tearing apart flesh, since the dinosaur was carnivorous. It is believed that since the eyes of Tyrannosaurus rex face front, rather than most other dinosaurs with eyes on the sides of their heads, eye placement makes T. rex a better hunter to judge depth and distance, essential for hunting prey. Despite T. rex's gigantic size, the dinosaur could not run faster than about 10 to 25 miles per hour. Since fossil evidence is all that remains of these magnificent giants, there is some debate as to how fast the dinosaur could go. Tyrannosaurus rex regularly shed their 60 teeth and grow new ones in their place, which is characteristic of a large predator. This trait comes in handy if they lose their teeth in a battle or while attacking prey. Holding the title of “world’s largest predator” to date, Tyrannosaurus rex was able to consume 500 pounds of meat with one bite using cone-shaped teeth designed to rip and tear into flesh. It is possible that Tyrannosaurus rex grabbed prey, but their short arms were not long enough to reach their mouths.|E

Coronatum||Ciliate, 60-90 x 30-50 microns, outline elongate oval to elliptical, widest at or behind mid-body; anteriorly and posteriorly broadly rounded; ventral margin almost straight and dorsal side conspicuously convex. Dorso-ventraly about 3:2 f1attened. Pellicle rigid and slightly notched; extruomes about 4 microns long, closely arranged beneath pellicle. Cytoplasm colourless and hyaline, often containing several to many refractile globules which are mostly 3-5 microns across and located in the posterior half of the cell. Contractile vacuole small, located slightly dorsally in posterior 1/5-1/6 of the cell length (at about level of cytostome). Food vacuoles usually large, with indefinable contents (possibly bacteria). Macronucleus roundish, usually with many globular nucleoli. In some speciemens only one large, centrally located nucleolus to be observed. Single oval to spherical micronucleus closely adjacent to macronucleus. Somatic cilia about 10 microns long, about 10-15 caudal cilia about 3 times as long as somatic ones, stretching always in radial manner; cilia of buccal apparatus 20-40 microns length. Movement moderately fast, somewhat drifting and wobbly, and then motionless for short periods on detritus. About 40 somatic kinetics extending over entire length of cell, which are shortened anteriorly and form thus an inconspicuous suture, while others terminate at the apical end and compose one large bold apical plate. Caudally one cilia-free area to recognise posterior to buccal field. all kineties in anterior 2/3 of body composed of (mainly) paired basal bodies, monokinetids posterioly. Left of buccal field mostly 4-5 shortened kineties. Adoral membranelle short, anteriorly with two rows of basal bodies: membranelle 2 bipartite - one part posteriorly hook-like, anteriorly and posteriorly distinctly 2-rowed, middle portion zig-zag shaped, second part V-shaped; membranelle 3 consistmg of 3 rows of basal bodies, which are arranged densely. Paroral membrane prominent and genus characteristic, about 4/5 of cell length with its posterior end strongly curved.|E

    Amanita muscaria

    Fly Agaric

    Amanita muscaria|Fly Agaric Mushroom||Amanita muscaria is a mycorrhizal basidiomycete fungus. Amanita muscaria is the classic European fairytale mushroom, bearing white gills and white warts on a typically bright red cap. It is known to contains several toxic, psychoactive compounds. This species was originally described from Europe and recent genetic and mophological evidence suggests that there are a number of distinct species worldwide that have been lumped under this name. |E

    Tremella mesenterica

    Witches Butter

    Tremella mesenterica|Witches Butter||Widely recognized by its yellow jelly-like shape, Tremella mesenterica or witches’ butter is a fungus that grows on decaying deciduous wood and sometimes on other fungi. This fungus appears on trees and wood after rain, and will be bright yellow in color. If there has been a lack of rain or moisture for some time, the fungus will appear shriveled and dark yellow or orange in color. If it rains again, the fungus will return to its regular yellow jelly-like state. Like most members of phylum Basidiomycota, Tremella mesenterica is considered a “jelly-fungus”. About 2.5 to 10 centimeters wide and 3 centimeters tall, this fungus can be found in North America, Europe, China, Japan and Taiwan and is most common in late Fall. There is an old European legend that if this fungus grows on the entranceway of a house, a witch has casted a spell on the people in that house. As the legend goes, the only way to remove the spell is to prick the witches’ butter, leaking out the internal fluids of the fungus and thereby killing the fungus but removing the spell. Witches’ butter has also been used in Asia as a remedy for lung ailments, however a recent study showed that ethanol extract from Tremella mesenterica decreased cell viability. Tremella mesenterica has been studied as an alternative source of fuel. The process the fungi uses to decompose lignin, a chemical compound in wood, involves two steps of saccharification and then fermentation. The product of these two steps is fuel ethanol. A possible source of fuel could come from bioengineering the fungus to produce mass quantities of ethanol for commercial consumption.|E
