Glossary for Mesoplodon stejnegeri
- Bathypelagic zone
- The one of an ocean below the 10degC thermocline down to a temperature of 4degC.
- A major class of ecologically similar communities of plants, animals, and other organisms. Biomes are defined based on factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and other factors like climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation.
- Body length (VT)
- The distance from point to point along the longest axis of the body of an organism.
- Body mass
- The amount of matter in the body of an organism.
- The general region of indefinite width that extends from the sea inland to the first major change in terrain features.
- Conservation status
- Continental shelf
- The extended perimeter of each continent, which is covered during interglacial periods such as the current epoch by relatively shallow sea.
- Continental slope
- The seabed below the end of the continental shelf (the shelf break). The continental slope is much steeper than the shelf; the average angle is 3, but it can be as low as 1 or as high as 10. The slope is often cut with submarine canyons.
- Data deficient
- A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases great care should be exercised in choosing between DD and a threatened status. If the range of a taxon is suspected to be relatively circumscribed, and a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified.
- This taxon is still in existence, as opposed to extinct.
- Extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- First Appearance (Older Bound)
- The older bound for the first appearance of this taxon in the fossil record, in Ma.
- First Appearance (Younger Bound)
- The younger bound for the first appearance of this taxon in the fossil record, in Ma.
- Geographic distribution
- A description of the geographic distribution, or range, of the taxon. Includes descriptions of global, regional, or political aspects of range and whether the taxon is native or introduced in portions of the range and endemicity.
- The natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.
- Habitat. (2013, August 9). In Wikipedia, The Free Encyclopedia. Retrieved 19:01, August 14, 2013, from http://en.wikipedia.org/w/index.php?title=Habitat&oldid=567783959
- A category or description of the habitat in which the Event occurred.
- Habitat breadth
- Number of habitat layers used by an organism
- Area of dry or relatively dry land surrounded by water or low wetland.
- Kilograms. A mass unit which is equal to the mass of the International Prototype Kilogram kept by the BIPM at Svres, France.
- Last Appearance (Older Bound)
- The older bound for the last appearance of this taxon in the fossil record, in Ma.
- Last Appearance (Younger Bound)
- The younger bound for the last appearance of this taxon in the fossil record, in Ma.
- Meters. A length unit which is equal to the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second.
- Marine habitat
- A habitat that is in or on a sea or ocean containing high concentrations of dissolved salts and other total dissolved solids (typically >35 grams dissolved salts per litre).
- Mesopelagic zone
- The zone of an ocean immediately below the photic zone down to a depth where the water temperature is 10degC (the thermocline).
- Million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- Pelagic zone
- An open ocean region.
- Population trend
- Saline water
- A large expanse of saline water usually connected with an ocean.
- The line of contact between a body of water and the land.
