Jalisco Harvest Mouse (Scientific Name: Reithrodontomys sumichrasti)

Common Name: Jalisco Harvest Mouse
Scientific Name: Reithrodontomys sumichrasti

Habitat

The Jalisco Harvest Mouse is primarily found in the mountainous regions of western Mexico, particularly in the states of Jalisco and Michoacán. Its habitat includes grasslands, agricultural fields, and shrublands at elevations ranging from 1,200 to 3,000 meters above sea level. This species prefers areas with dense vegetation that offers cover and food resources.

Physical Characteristics

Jalisco Harvest Mice are small rodents, typically measuring 10 to 20 cm in length, including their tail. They have a slender body covered in soft fur that is predominantly light brown to gray, with a lighter underbelly. Characteristically, they have large eyes and ears, aiding in their nocturnal lifestyle. The tail is often long and scaly, providing balance as they navigate through their habitat.

Behavior

This species exhibits a primarily nocturnal behavior, becoming active during the night to forage for food while avoiding daytime predators. They are known for their agility and climbing abilities. Jalisco Harvest Mice often engage in social behaviors, living in small groups and communicating through a series of high-pitched sounds. Nesting habits are also notable, as they construct intricate nests from grasses and other materials close to the ground.

Diet

The diet of the Jalisco Harvest Mouse consists mainly of seeds, grains, and various plant materials. They are particularly fond of cultivated crops, such as corn and beans, which can often lead them to forage in agricultural areas. Their foraging habits are essential for seed dispersal, contributing to ecosystem health.

Reproduction

Jalisco Harvest Mice exhibit seasonal breeding behavior, typically mating during the warmer months, from late spring to early fall. The gestation period lasts approximately 24 days, resulting in litters of 3 to 6 young. These offspring are weaned within a few weeks and reach sexual maturity around 2 to 3 months of age, allowing for multiple breeding cycles within a year.

Conservation Status

The Jalisco Harvest Mouse is currently listed as ‘Vulnerable’ on the IUCN Red List due to habitat loss from agricultural expansion and urban development. Conservation efforts are crucial to preserve their natural habitats and ensure their survival.

Interesting Facts

One interesting fact about the Jalisco Harvest Mouse is its remarkable ability to adapt to varying environmental conditions. This species can thrive in agricultural landscapes, often taking advantage of human-altered habitats. They are also known for their impressive jumping abilities, aiding in their escape from predators.

Role in Ecosystem

The Jalisco Harvest Mouse plays a vital role in its ecosystem by acting as both a seed disperser and a prey species. Their feeding habits help promote plant growth and biodiversity, while they serve as a food source for various predators, including birds of prey and snakes. This interconnectedness underscores the importance of preserving their populations as part of a balanced ecosystem.
