Peromyscus aztecus occurs in the mid- to high elevations in many mountain ranges in the highlands of Mexico and Central America. Aztec mice have been found in southwestern Jalisco, Michoacan, and central Veracruz, through the volcanic belt. These mice are found in the Mexican States of Puebla, Morelos, Hidalgo, Guerrero, Oaxaca, and Ciapas, as well as into Central America.
Biogeographic Regions: nearctic (Native )
The diet of P. aztecus consists of many different things depending on their location and time of year. In Guerrero, they eat primarily grasses and seeds. In Jalisco, they eat monocot seeds in the dry-hot and cold seasons, and then dicot leaves in the wet season. Some other forms of food for P. aztecus may include insects, and dicot fruits.
Animal Foods: insects
Plant Foods: leaves; seeds, grains, and nuts; fruit
Foraging Behavior: stores or caches food
Primary Diet: omnivore
Aztec mice serve as food for many different predators. One negative role that P. aztecus may play in relationship to the ecosystem is the fact that they may retard forest regeneration. They are a force of destruction to seeds, specifically coniferous seeds.
Possible predators of P. aztecus include barn owls (Tyto alba), coyotes (Canis latrans), bobcat (Lynx rufus), and weasels (Mustela frenata). Aztec mice avoid predation by blending into their habitat, or they may run into burrows or crevices.
Known Predators:
Anti-predator Adaptations: cryptic
Peromyscus aztecus is a medium sized member of the genus Peromyscus. Individuals weigh between 22 and 36 g, and are from 197 to 260 mm in length. The fur is a pale ochre with black dorsally. The flanks are reddish, and the under parts are light buff. A black ring around the eye is present. The feet are white. The tail is bicolored with a white tip and is about as long as the body. Other measurements include: hind foot, 22.5 to 29 mm; ear, 15.5 to 21.5 mm; average length of skull, 33.3 mm; and the average size of the rostrum, 13.8 mm
Range mass: 22 to 36 g.
Range length: 197 to 260 mm.
Other Physical Features: endothermic ; heterothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
In the wild, most individuals probably won't live past 2 years. The longest known record of longevity for Peromyscus in a laboratory is 8 years and 4 month (Peromyscus maniculatus).
Typical lifespan
Status: wild: 0.5 to 2 years.
Aztec mice occur at elevations between 1,000 m to 2,700 m. Vegetation types in their habitat are variable, and dependon the location. In Michoacan, the vegetation consists of montane, boreal coniferous forests. In Jalisco, pine/oak habitat and cloud forest cover the area. In Guerrero, P. aztecus occupies the cloud, oak, and pine/oak habitat types. Juniper forests are the used area in volcanic regions. These rodents often occur in fields with poor cover and abandoned agricultural fields.
Range elevation: 1000 to 2700 m.
Habitat Regions: temperate ; tropical
Terrestrial Biomes: savanna or grassland ; forest ; scrub forest
Other Habitat Features: agricultural ; riparian
An important role that P. aztcus may play economically for humans is that they may be used for many genetic and physiological studies in labs. They are clean, live well in the lab, are easily fed, and their reproductive rate is very high.
Positive Impacts: research and education
Currently, there are not a lot studies done on P. aztecus. The paper authored by Vazquez, et al., is a compilation of most of what is known about this species.
Tactile communication is used when grooming as a friendly interaction, as well as during biting in defense and aggression. Chemical communication is usually related to marking behavior. This involves olfactory methods of recognition. Visual communication is less important in this species because of their nocturnal activity. However, body postures probably communicate intent when two animals meet. These animals can detect movement in little light and see short distances in the dark.
Communication Channels: visual ; tactile ; acoustic ; chemical
Other Communication Modes: scent marks
Perception Channels: visual ; tactile ; acoustic ; chemical
Aztec mice are not listed by CITES or IUCN.
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
There are many species of parasites that are found in relationship with the Peromyscus genus: pentastomids, acanthocephala, trematodes, cestodes (tapeworms), nematodes, mites, chiggers, ticks, fleas, lice, and diptera. Many of these parasites carry infectious diseases. Fleas may carry plague as well as typhus.
Negative Impacts: causes or carries domestic animal disease
Aztec mice are monogamous. A male and female will form a pair, and participate in joint rearing of the young.
Mating System: monogamous
Peromyscus aztecus breed throughout the year if it is not too cold or too hot. The peak of the reproductive season is March to July. Individuals become mature enough to mate at about the same time that they develop their sub-adult pelage. The normal gestation period of this species is about 21 to 27 days. The average litter size is reported to be 3.4. Time of weaning is 3 to 4 weeks. The reproductive performance may decline after 3 to 5 litters or when a female reaches about 18 months of age. Sexual behavior includes grooming, driving, mounting, intromission, and ejaculation.
Breeding interval: These mice can breed every month or so while weather conditions permit it.
Breeding season: P. aztecus breeds from March to July.
Average number of offspring: 3.4.
Range gestation period: 21 to 27 days.
Range weaning age: 3 to 4 weeks.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Parental care is most demonstrated by the female. Mother mice provide milk, grooming, and protection for their altricial young until they are able to leave the nest. However, the male of a mated pair may stay at the nesting site to help the rearing of the young. Male parental behavior may include grooming the young and huddling over them to help keep them warm and safe.
Parental Investment: no parental involvement; altricial ; pre-fertilization (Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Male, Female); pre-independence (Provisioning: Male, Female, Protecting: Male, Female)

The Aztec mouse (Peromyscus aztecus) is a species of rodent in the family Cricetidae, native to southern Mexico and parts of Central America.
The Aztec mouse is a typically sized member of its genus, with a total length of 20 to 26 cm (7.9 to 10.2 in), about half of which is made up by the tail. The fur is ochre mixed with black over the upper surface of the body, a brighter reddish color at the sides, and pale buff beneath. The tail is also paler on the underside, and often ends with a white tip. The feet are white, with hairs on the soles of the hindfeet, one of the features that allows it to be distinguished from the otherwise similar looking, and more widespread, brush mouse.[2]
Aztec mice are found in three disjunct regions of southern Mexico, in southern Guatemala and Honduras, and in much of El Salvador.[1] Four subspecies have been identified:[2]
The mice live in mountainous regions, between 1,000 and 2,700 m (3,300 and 8,900 ft) altitude.[2] Here they are found in the limits of humid highland forests, ranging from cloud forests to highland coniferous forest dominated by juniper and pine. They are also found in sugar cane and coffee plantations.[1]
Aztec mice primarily eat grasses and seeds,[2] although as much as a third of their diet may consist of insects at certain times of the year, including ants, crickets, beetles, and weevils. Although precise details of their mating habits are unknown, pregnant females have been found from May to November, and litter sizes of up to five have been recorded.[2]
The Aztec mouse is not a threatened species. Its conservation status is of least concern because its large distribution, a presumed large population, and its tolerance to various kinds of habitats. Since it lives in protected areas and no threat is apparent, it is unlikely to decline to levels of threatened species.[1]

Peromyscus aztecus, também conhecido como camundongo asteca, é uma espécie de roedor da família Cricetidae. Ocorre em algumas regiões da América Central.
O Peromyscus aztecus ocorre em regiões temperadas e montanhosas. Prefere viver nos limites das florestas úmidas em terras altas. Seu hábitat são normalmente terras entre 500 m e 3200 m de altitude, em relação ao nível do mar. Pode viver também em plantações de cana-de-açúcar e café.[1]
É principalmente insetívoro. Alimenta-se de formigas, grilos, besouros e carunchos. Também come algumas sementes (em especial do gênero Solanum) e vegetais.[1]
A espécie ocorre em algumas regiões disjuntas entre si: no centro de Veracruz e de Guerrero, em Oaxaca e no leste de Chiapas, além de Guatemala, Honduras e El Salvador.[1]
O camundongo asteca não está ameaçado de extinção. Seu estado de conservação é pouco preocupante porque a espécie tem grande área de distribuição, possivelmente uma grande população e tolera vários tipos hábitats. Como habita áreas de proteção ambiental e aparentemente não sofre nenhum tipo de ameaça, é pouco provável que sua população entre em declínio.[1]

Peromyscus aztecus[2][3] är en däggdjursart som först beskrevs av Henri Saussure 1860. Peromyscus aztecus ingår i släktet hjortråttor, och familjen hamsterartade gnagare.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade i Catalogue of Life.[4]
Arten blir 10,9 till 12,6 cm lång (huvud och bål), har en 10,8 till 14 cm lång svans och väger 33 till 57 g. Bakfötterna är 2,3 till 2,6 cm långa och öronen är 1,8 till 2,1 cm stora. Pälsen på ovansidan har en rödbrun färg. Den blir mer orange mot kroppssidorna och buken är vit. På svansen förekommer korta hår och den är mörkare på ovansidan. Peromyscus aztecus har smala mörka ögonringar. Vuxna exemplar är tydligare orange än andra hjortråttor från samma region.[6]
Denna hjortråtta förekommer från mellersta Mexiko (Veracruz och Guerrero) till Honduras. Den vistas i regioner som ligger 500 till 3200 meter över havet. Arten hittas främst vid kanterna eller i undervegetationen av tempererade skogar. Den besöker även odlade områden.[1]
Födan utgörs främst av insekter som kompletteras med frön och gröna växtdelar.[1]
