Eva's desert mouse (Peromyscus eva) is a species of rodent in the genus Peromyscus of the family Cricetidae found only in the Baja California peninsula of Mexico. [2]
Eva's desert mouse measures 19 cm (7.5 in) from head to rump, on average, and has a 10 cm (3.9 in) tail. They weigh between 13 and 20 grams (0.46 and 0.71 oz). The fur is russet or buff in color over most of the body, with pale grey markings on the nose, cheeks, and around the eyes. The ears are pale brown and almost hairless, and the underparts creamy white. It can most clearly be distinguished from the cactus mouse, which is found in the same geographical region, by the shape of the baculum, although it is also typically darker in color, and with a longer tail. [3]
Little is known of the animal's biology, although it is usually found close to succulent plants, and appears to breed between February and July. [3]
Eva's desert mouse lives only in the southern part of the Baja California peninsula in Mexico. Within this region, it inhabits scrubland habitats below 1,800 m (5,900 ft) dominated by plants such as cholla, Jatropha , and organ-pipe cactus, and in agricultural land. [3] Two subspecies have been identified:
The Perote mouse, or Perote deer mouse, is a species of rodent in the family Cricetidae. It is found only in Mexico.
Burt's deer mouse is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is found only on Montserrat Island off the east coast of Baja California Sur. The species is threatened by predation by feral cats.
Dickey's deer mouse is a species of rodent in the family Cricetidae. It is endemic to Mexico, being found only on a small island in the Gulf of California. The species is named for Donald Dickey, who sponsored the expedition that first discovered the animal.
The cactus mouse is a species of rodent in the family Cricetidae. It is a species of the genus Peromyscus, a closely related group of New World mice often called "deermice". They are native to desert areas of southwestern North America.
The Angel Island mouse, or La Guarda deermouse, is a species of rodent in the family Cricetidae.
Hooper's mouse is a species of rodent in the family Cricetidae. It is the only member of the Peromyscus hooperi species group, and is found only in Mexico. The species is named for Emmett Hooper, a researcher into the taxonomy of the genus Peromyscus.
The San Lorenzo mouse is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is found only from the islands of San Lorenzo Norte, San Lorenzo Sur, and Salsipuedes off the east coast of Baja California. The species is threatened by predation by feral and domestic cats, particularly on San Lorenzo Sur.
The Tres Marías island mouse or Tres Marías deer mouse is a species of rodent in the family Cricetidae. It is found only on the Islas Marías off the west coast of Mexico. When last assessed, it was common on María Cleofás Island, but rare or absent on the other, more disturbed, islands.
The black-eared mouse, or black-eared deer mouse, is a species of rodent in the family Cricetidae, native to North America.
The Mexican deer mouse is a species of forest-dwelling rodent in the family Cricetidae. It is found in southern Mexico and throughout much of Central America.
The white-ankled mouse is a species of rodent in the family Cricetidae.
The tawny deer mouse or marsh mouse is a species of rodent in the family Cricetidae. It is found only in Mexico.
The false canyon mouse or Coronados deer mouse, is a species of rodent in the family Cricetidae. It is known only from Coronados Island, a small island in the Gulf of California, part of Baja California Sur, Mexico. The species is threatened by predation by feral cats, and the IUCN has assessed its conservation status as "critically endangered".
The Santa Cruz mouse is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is found only on two small islands in the southern Gulf of California. Feral cats on Santa Cruz Island are a threat.
Slevin's mouse, also known as the Catalina deer mouse, is a species of rodent in the family Cricetidae. It is endemic to Isla Santa Catalina off the east coast of Baja California Sur, an island with an area of about 40 km2 (15 sq mi), and it is the only native mammal on the island. It is named for Joseph Slevin, a curator at the California Academy of Sciences.
Winkelmann's mouse is a species of rodent in the family Cricetidae found only in Mexico, and is named for John R. Winkelmann, who collected the first specimens.
The little desert pocket mouse is a species of small rodent in the family Heteromyidae. It is endemic to Baja California in Mexico.
Nelson's pocket mouse is a species of rodent in the family Heteromyidae. It is found in Mexico and in New Mexico and Texas in United States. It is named in honor of the American naturalist Edward William Nelson.
The black jackrabbit is a species of mammal in the family Leporidae. Endemic to Mexico, its only known location is Espiritu Santo Island in the Gulf of California. The IUCN has listed this species as a "vulnerable species" because of its restricted range. This taxon is regarded by some authorities as being a subspecies of the black-tailed jackrabbit, found on the mainland of Mexico.
The Northern Baja deer mouse is a species of deer mouse native to Southern California and the Baja California peninsula as well as several islands in the Gulf of California. P. fraterculus was previously considered a subspecies of the cactus mouse prior to a 2000 study which identified genetic differences and suggested P. fraterculus is more closely related to Eva's desert mouse than to P. eremicus.
