Species Description: Carcelén’s Bristly Mouse

Common Name: Carcelén’s Bristly Mouse
Scientific Name: Oryzomys carceleni

Habitat

Carcelén’s Bristly Mouse is primarily found in the montane forests and shrublands of the Andes Mountains, particularly in regions of southern Ecuador. This rodent thrives in high-altitude environments, typically ranging from 1,500 to 3,000 meters above sea level, where it prefers areas with dense undergrowth and ample cover.

Physical Characteristics

Carcelén’s Bristly Mouse exhibits several distinct physical features that make it recognizable. It typically reaches a body length of 8 to 12 centimeters, with a tail that adds an additional 9 to 11 centimeters. The fur is coarse and bristly, primarily brown with lighter underbellies, featuring a unique pattern of darker markings on its back. Notably, its large ears and prominent whiskers enhance its sensory capabilities, aiding in navigation through its dense habitat.

Behavior

This species displays predominantly nocturnal behavior, being most active during the night. Carcelén’s Bristly Mouse is known for its adept climbing skills, often foraging in shrubs and trees for food. It tends to live in social groups, utilizing communal nesting to enhance warmth during colder nights. Territorial marking with scent glands is also common, helping to establish boundaries with neighboring groups.

Diet

Carcelén’s Bristly Mouse primarily feeds on a herbivorous diet, with a particular preference for seeds, fruits, and leafy greens found in its mountainous habitat. Grasses and wildflowers provide essential nourishment, making this species a key consumer within its ecosystem. The mouse is also observed engaging in opportunistic feeding behavior, occasionally nibbling on insects, demonstrating its adaptability in dietary choices.

Reproduction

The mating season for Carcelén’s Bristly Mouse typically occurs from late spring to early autumn. After a gestation period of about 25 days, females give birth to 3 to 5 offspring in a single litter. Maternal care is intense, with females nurturing their young in hidden nests made of grass and leaves. Young mice are weaned after three weeks and reach sexual maturity within two months.

Conservation Status

Currently, Carcelén’s Bristly Mouse is classified as ‘Endangered’ due to habitat loss stemming from agricultural expansion and deforestation. Conservation efforts are crucial to preserve this unique species and its mountainous habitat, where its ecological role is vital.

Interesting Facts

One fascinating fact about Carcelén’s Bristly Mouse is its ability to store food during periods of abundance, creating a reserve for harsher seasons. Additionally, this species is a key food source for various predators in the Andes, highlighting its importance within the food web.

Role in Ecosystem

Carcelén’s Bristly Mouse plays a significant role in the ecosystem as both a seed disperser and a prey species. By consuming and redistributing seeds, it aids in plant propagation, while its presence supports local predator populations, creating a balanced ecological network within its mountainous environment.
