Distribution
Range Description
The range of subspecies preblei has not been well defined, but most occurrences are along the Front Range of Colorado and the southeastern section of Wyoming. The current range in Wyoming probably is restricted to a few isolated patches of suitable habitat in primary drainages and adjacent lowland grasslands (Compton and Hugie 1993).
The range of subspecies luteus includes portions of New Mexico, Arizona, and Colorado. The New Mexico range includes the San Juan Mountains (El Rito area), Sangre de Cristo Mountains (North Williams Lake), Jemez Mountains (upper Guadalupe River drainage), Sacramento Mountains (Rio Penasco and Silver Springs Creek), Rio Grande Valley (Espanola to the Bosque del Apache NWR), and lower Rio Chama Valley (Morrison 1992). Arizona range includes the White Mountains, southern Apache County, and northern Greenlee County (Hoffmeister 1986). Jones (1999) reported this subspecies from western Las Animas County, southern Colorado.

Geographic Range
Meadow jumping mice may be found throughout northern North America. They are found from the Atlantic Coast to the Great Plains in the United States, northward throughout the north eastern and north central states to the arctic tree-line of Alaska and Canada, and as far south as Georgia, Alabama, Arizona, and New Mexico. They have the widest known distribution of mice in the subfamily Zapodinae.

Physical Description
Morphology
Physical Description
Meadow jumping mice range in length from 180 to 240 mm, with the tail accounting for 108 to 165 mm. The hind feet are 28 to 35 mm long.
Mass varies substantially with the season. Summer weights range between 11.15 and 24.8 grams, averaging between 16 and 19 g. Prior to hibernation, meadow jumping mice may attain weights up to, or greater than, 35 g.
Meadow jumping mice are recognized for their extremely long tails and long hind feet. Small and slender, they differ from woodland jumping mice in that they do not have a white-tipped tail and are generally duller in color. Adults have a dorsal dark or olive brown band, which is paler in juveniles. The sides are a pale yellowish-brown, with black hairs lining the flanks, and the underparts are white or buffy-white. The tail is sparsely haired, dark brown on top and yellow-white on the bottom, and exceeds the body length. The pelage is short, thick, and predominantly coarse. These mice undergo an annual molt that usually commences after mid-June for adults or in August for the juveniles and lasts for about three weeks. Meadow jumping mice have small and delicate forelimbs with four toes on each foot. The hind limbs are longer and have five toes. The feet have naked soles. The head is small, narrow, and relatively high crowned. The nose is short and pointed. These mice have large infraorbital foramen. Dental formula is 1/1, 0/0, 1/0, 3/3. Meadow jumping mice are the only mammal with eighteen teeth. The upper jaw is characterized as follows: short, narrow, and longitudinally grooved incisors; small cheek teeth; and a small peg-like premoloar that generally precedes the molars. These mice have 8 mammary glands, 4 inguinal, 1 pectoral, and 1 abdominal. Females may sometimes be slightly larger and weigh more than males.
Range mass: 12 to 30 g.
Average mass: 18.25 g.

Ecology
Habitat
Habitat and Ecology
Breeding occurs from April to early September, with a peak in June-August. Gestation lasts 17-20 days. Litter size is 2-9 (average 4-6); individual females may produce up to 2-3 litters per year. Young are born May-early October, weaned and independent in about four weeks. Most first breed in the summer following their birth. Maximum longevity 2-3 years.
Jumping mice are basically solitary. May shift activity area in response to seasonal drying of habitat. Home range generally is about one hectare in males, smaller in females.
The activity pattern of this mouse is primarily nocturnal, but it is also crepuscular. Preparations begin for hibernation around the beginning of September as individuals accumulate about six grams of additional body fat to last through the winter. Hibernation occurs from September/October to April/May.

Habitat
Meadow jumping mice may live in various habitats that have some herbacious cover, but moist grassland is preferred and heavily wooded areas are avoided. Grassy fields and thick vegetated areas bordering streams, ponds, or marshes generally support greater numbers. It is possible that these mice prefer habitats with high humidity.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: savanna or grassland ; mountains
Wetlands: marsh
Other Habitat Features: riparian
Trusted
Comments: Moist lowland habitats; prefers relatively thick vegetation of open grassy and brushy areas of marshes, meadows, swamps, and streamsides. When inactive, occupies underground burrow, usually in a bank or hill (winter), or under log or grass clump. Young are born in nest underground or under other cover.
Trusted
Migration
Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Trophic Strategy
Food Habits
Meadow jumping mice primarily eat seeds, but also feed on berries, fruit, and insects. Grasses may be cut in sections to reach the seed heads. These mice may leave these piles of grass debris with rachis and glumes on the surface. In the spring, one half of the diet may consist of animal foods after emergence from hibernation. Especially important are Lepidoptera larvae and beetles of the familia Carabidae and Curculionidae. Later, seeds and the sporocarps of hypogeous fungi (e.g. Endogone). Weight generally increases toward the beginning of the fall, especially two weeks before hibernation begins, as sufficient accumulated fat is required for hibernation.

Ecosystem Roles
Meadow jumping mice are an important food source for many predators, and may play a role in spreading the seeds of some of the plants they eat. They have few parasites.
Ecosystem Impact: disperses seeds
Trusted
Predation
Predators of meadow jumping mice include great horned owls, screech owls, red-tailed hawks, weasels, and foxes. If startled, these mice leap up to 1 m high in the air (hence, their common name) and then either short hop or crouch, flattening their brighter underparts against the ground. This stillness is apparently their primary defense against predators.

Reproduction
Reproduction
No information is available on the mating system of meadow jumping mice.
The breeding season of meadow jumping mice occurs shortly after hibernation in late April or May. Males emerge from hibernation slightly prior to females and are reproductively active when the females emerge. Within two weeks after emergence, the majority of females are pregnant and gestation begins. Gestation is usually about 18 days, but may be longer for lactating females. A female may have 2 to 3 litters in a year. The average litter size is 5.3, though the number of young varies between 2 and 9. In the north, most young are born and weaned between June and August. Small and weighing about 0.8 g, the neonates are naked, pink, blind, clawless and deaf, but squeak audibly at birth. In the first week, their ear pinnae unfold, fur begins to cover their backs, and their claws appear. They begin crawling between the first and second weeks, and by the third week they can hop, creep, and hear. Their incisors have erupted, and they have tawny coats. By the end of the fourth week, the young have adult pelage, and open eyes. Weaned, they are independent between the 28th and 33rd day. Those young females born during the spring may reproduce after two months.

Trends
Population
Estimated populations of subspecies preblei at extant locations are generally less than 50, except at the Air Force Academy, Rocky Flats, and potentially East and West Plum Creeks in Douglas County. Available information suggests that this mouse never was abundant at any of the known historical locations (Armstrong 1972). It is documented in Colorado by approximately 18 historical records and seven extant occurrences in Boulder, Jefferson, Douglas, Elbert, Larimer, Weld, and El Paso counties. Long term monitoring and inventory will be needed to determine trends in distribution and population parameters. Because so little is known about the populations in Colorado, it is difficult to determine long-term trends. However, because the habitat is under intense pressure due to urbanization and improper land management, it is likely numbers are declining rangewide. There is some evidence that populations have a tendency to fluctuate in size from year to year (Ellingson et al. 1995). Inventory is needed throughout the historic range. Potential sites could be identified through aerial photographic analysis.
Through the mid-1980s, subspecies luteus had been reported from 14 sites in New Mexico and 11 sites in Arizona. Since then, it has been found in at least three localities in Colorado (Jones 1999) and additional sites in New Mexico (Morrison 1992) and Arizona (Arizona Game and Fish Department map, dated 1 January 2004, shows about 14 localities, some closely adjacent). Long-term trends are poorly known, but available evidence suggests stability. For example, in the late 1980s, Morrison (1992) determined that luteus still occurred in all resurveyed sites in New Mexico and found this subspecies in additional sites in the Jemez and Sacramento mountains, Rio Grande Valley, and the lower Rio Chama Valley. Further surveys are needed to determine the full distribution and area of occupancy.

Threats
Threats
For subspecies preblei conversion of riparian systems because of urbanization, improper grazing, and agriculture methods, and improper gravel mining practices are likely threats (Bakeman et al. 1997, USFWS 1998). Invasive non-native plants (and consequent weed-control programs) may also threaten the habitat (USFWS 1998). It is important to keep in mind that little is known about the population dynamics of this subspecies. Thus, evaluations of viability should be made very carefully.
For subspecies campestris overgrazing of riparian areas by domestic stock has resulted in the loss of much of the suitable habitat. Such overgrazing is still considered to be the main threat to this subspecies.
Because of subspecies luteus reliance on limited mesic grassland and riparian areas, habitat destruction is of major concern. Agricultural development, including livestock grazing, has destroyed or severally altered riparian habitat in New Mexico and Arizona. Increased recreational use and development in the Sacramento Mountains may further reduce existing habitat patches.
Trusted
Comments: In the West, overgrazing by cattle may remove required vegetative cover and degrade habitat (Clark and Stromberg 1987).

Management
Conservation Actions
The conservation status of Preble's jumping mouse has been a contentious issue. This subspecies was listed as threatened under the United States Endangered Species Act in 1998. However, investigations of mitochondrial and microsatellite DNA by Ramey et al. (2005) led to questions regarding the validity of subspecies classification and resulted in a movement to delist Preble's jumping mouse (Hall 2006). The delisting proceedings have been suspended to allow for a review of King et al. (2006) which argues against the methodology and findings of Ramey et al. (2005). Preble's jumping mouse is protected at the state level. The Wyoming Department of Game and Fish gives it Priority II status and it is designated a Colorado non-game species, providing legal protection.
The United States Air Force Academy and the Rocky Flats Environmental Technology Site support populations of subspecies preblei that are well protected. Additionally, Boulder City Open Space, Jefferson County Open Space, and other local programs have some level of protection. However, because many populations or known locations are influenced by off-site considerations, such as stream hydrology, each location should be monitored to determine the status of the population. The floodplain and wetland habitats often used by this species are protected to various extents by state and federal regulations. Protection of habitat should be attained through land acquisition, special designation, private landowner agreements, and natural resources management planning.
Subspecies campestris is classified as Critically Rare with habitat decreasing in South Dakota. The Wyoming Department of Game and Fish give it Priority II status on the grounds that further research is required to determine the level of management required to protect the species. No populations are known to occur in any protected areas or in captivity.
Currently subspecies luteus is listed as threatened by Arizona Game and Fish Commission and by New Mexico Department of Game and Fish. Findings that the New Mexican jumping mouse is able to utilize irrigation ditches have suggested that populations may be less threatened than originally believed (Morrison 1990, cited in NMGF, 2004). These initial findings should be more closely studied before any changes in conservation status occur. This subspecies would benefit from protection of high quality riparian zones and restoration of degraded (e.g., over-grazed or eroded) riparian zones.

Meadow jumping mouse
The meadow jumping mouse (Zapus hudsonius) is the most widely distributed mouse in the subfamily Zapodinae. It may be found from the Atlantic coast, to the Great Plains, as far north as the arctic tree lines in Canada and Alaska, and as far south as Georgia, Alabama, Arizona, and New Mexico.[2]
Contents |
Description
The meadow jumping mouse can range in length, from 180 mm to 240 mm, with its tail taking credit for most of its length, usually about 108 mm to 165 mm. A distinct characteristic about this species is its enlarged hind feet, which can be, 28 to 35 mm long, and relatively short forelimbs. This gives it a Kangaroo rat like look to it, although its tail shows that it is not a Kangaroo rat because it is not bushy at the tip. The pelage of this creature is short, and with somewhat dense, coarse hair. The color of the pelage has a few variations, but a broad dorsal stripe is always present. This broad dorsal stripe is of a darker brown color, with black tips, giving it somewhat a grayish appearance to it. The sides are usually a lighter color, usually bright yellow to orange, and the under body is usually white, matching the color of its feet. These mice have eight mammary glands, four inguinal, two pectoral, and two abdominal. The male genitalia are inconspicuous except during mating season when the scrotal sac becomes enlarged, and more visible. The tail which again makes up most of this creature's body is bicolored, showing a darker color from above, and a lighter color below. It is lightly covered with hair, which gets longer as it approaches the tip, but does not get bushy like the Kangaroo rat. Its ears are very noticeable, and its whiskers are prominent. The head is small, and narrow, and it is considered to be relatively high crowned. The nose is short, yet it is pointy, and the eyes are relatively big. These mice also have a large infraorbital foramen. With the exception of the Aye-Aye, the meadow jumping mouse is the only mammal to have eighteen teeth with a dental formula of: 1/1, 0/0, 1/0, and 3/3. The upper jaw is short, and narrow. The incisors are longitudinally grooved, and its cheek teeth are small. Preceding the molars is a small peg-like premolar. As a whole the female jumping mouse is slightly larger, and heavier than the male, but their weight varies quite a bit depending on the season. Their weight during summer seasons can range from 11.15 grams to 24. 8 grams, with an average at about 16 to 19 grams. Just prior to hibernation, jumping mice can obtain a weight of 35 grams or larger.[3]

Habitat
Meadow jumping mice prefer a habitat which is high in humidity. Although they may live in many different areas usually with high herbaceous cover, they prefer moist grasslands, and avoid heavily wooded areas. High numbers are usually found in grassy fields, and thick vegetated areas with streams, ponds, or marshes nearby. They prefer large open areas to thickly wooded areas. As was stated before they are found in large parts of the United States, and up to Canada.[4]
Behavior
The most interesting characteristic of the meadow jumping mouse is its saltatorial powers. Quimby states that there is large disagreement, dating back to 1899, as to how high the jumping mouse can actually jump. In 1899 Preble documented that the meadow jumping mouse can jump six to eight feet when disturbed, and in some instances it may be able to jump further. Then in 1909 Seton stated that it can creep through the grass without hopping, and then suddenly can leap out a distance of ten to twelve feet. Later in 1926 Bailey says that there are no standards as to how long or far Z. hudsonius can leap. He states that it is capable of long leaps, short hops, and also it can creep through the grass on all fours without having to leap at all and without any difficulty at all. Finally in 1935, Townsend was able to witness a leap of two feet, and many more studies afterwards and to the date have concluded that the meadow jumping mouse is capable of jumping anywhere from two to three feet depending on the situation. Under less than normal situations the jumping mouse has been measured to jump a few inches longer than three feet, again this was during a study, and not at all under normal conditions. What is clear is that the meadow jumping mouse is capable of leaping a good sized distance compared to its body size. The initial leap of the jumping mouse when startled from a squatting position is long; the following hops are shorter but much more rapid. When not alarmed the normal locomotion method is little hops of one to six inches.[3]
The meadow jumping mouse is a decent swimmer, it usually will jump in when retreating from danger, or it was noticed as well to jump in when being set free. Its method of aquatic locomotion is very similar to its locomotion on land. At first it pushes off with long thrusts using only its hind feet simultaneously, mimicking its long jumps on land. Afterwards, the jumping is followed by movement of all four limbs, in an almost doggy-paddle-like form, with its head held high above the water. The meadow jumping mouse is also capable of diving, and a maximum distance of four feet was recorded.[3]
The jumping mouse is an excellent digger; it usually burrows in a depression, and begins to dig horizontally with its front limbs, once inside it also uses its powerful hind feet to throw out the loose soil.[3] The meadow jumping mouse is primarily nocturnal, but has been captured in the late evening of a cloudy moist day. This could be because they are coming out to feed a bit earlier because of the conditions, but for the most part all activities occur during the night. The jumping mouse is a docile creature when handled; amongst its kind it is also pretty calm. There is very little territorial strife amongst them, but by no means are they social creatures. They are solitary animals, rarely if ever seen in pairs, but to contrast that, they are not aggressive towards each other either.[2]
Diet
The food preference of the meadow jumping mouse consists of seeds, but they also eat berries, fruit and insects. Usually right after emerging from hibernation they will eat the larvae of insects such as butterflies, and beetles of the family Carabidae, and Curculionidae. Later they will feed on seeds, and endogone which is a fungus. Towards the beginning of fall they start to gain weight in order to get ready for hibernation. Usually two weeks before hibernation is when they began to store up enough fat, and the greatest weight gain is noticed. Overall the meadow jumping mouse is considered to be a granivore, but can also be classified as an herbivore.[5]
In 1947 a study was done to see what the jumping mouse preferred for food. For this study many caged jumping mice were fed forty species of plants representing 20 different families. They were also fed many different fruits, such as apples, pears, and also given grains such as oatmeal. To test if they would eat anything they were given, they were also fed prepared rat and mouse concentrate. Twenty-eight species of insects, pertaining to ten different orders were collected and fed to the jumping mouse. All were partially or completely eaten except for lady bugs, carrion beetles, and one of the larvae Lepidoptera. It is not easy to say which member of a given area prefers which insect but as a whole insects do compose an important part of the jumping mouse’s diet. By the time the study was concluded they could not say that any particular mouse from any given area preferred one type of food over another. However when the meadow jumping mice were fed plants, they consumed the only the seeds of some and the roots of others, but the plant itself usually stay intact.[3]
Hibernation/Reproduction
Hibernation begins around late September and early October. At the moment of entering hibernation there is a decrease in metabolism, because of the jumping mouse going into torpor. Hibernation lasts until about mid April to May, with males and females emerging at about the same time with males emerging slightly earlier than females. From the time that the meadow jumping mouse goes into hibernation to the time it comes out there is a significant amount of weight loss. When the male emerges from hibernation it starts feeding and is immediately reproductively active. Once the female emerges which is only a short time after the males, they began mating, and only about two weeks after emergence all the females are pregnant and gestation begins. Gestation lasts about eighteen days, although this can be a bit longer if the female is still nursing her previous litter. The average litter size is said to be 5.3 young, but can range anywhere from two to nine young. The jumping mouse is capable of having two to three litters per year, with most litters weaned between June and August. Studies have shown that on average the jumping mouse has a litter during late spring after emergence and then again in later summer, with very little reproductive activity in mid summer.[3]
Young
The newborn young are small, naked, blind, deaf and have no claws. The only thing that these tiny newborns weighing 0.8 grams are able to do is make sounds. After only one week their body begins to get covered with fur and their claws start growing in. Their ear pinnae start to unfold and their hearing begins to develop. Between the first and second week they begin to crawl, and by the third week they are able to hop, and more importantly their hearing has completely developed. Approaching the fourth week their incisors are growing in and by the end of the fourth week they have their adult pelage, and wide open functional eyes. They are weaned and fully independent within twenty-eight to thirty-three days.[2]
Predators
The meadow jumping mouse has many predators ranging from owls, foxes, hawks, and weasels.[2] There are also other predators which have been spotted having meadow jumping mice either in their stomachs, or in their mouths. Examples of such creatures are common house cats, a Northern Pike, rattlesnakes, and a Green Frog (Rana clamitans).[3]
Conservation Status
The meadow jumping mouse is currently not in any kind of danger. According to the IUCN Red list, it is widely spread, common, and not declining throughout most of its extensive range. It is also present in many protected areas, and so does not have any major threats of it becoming an endangered species.[1]
