Species Description: Otro Cerro Pericote

Common Name: Otro Cerro Pericote
Scientific Name: Abrothrix olivacea

Habitat:
Otro Cerro Pericote is primarily found in the temperate forests and shrublands of the Andean regions in South America, particularly in parts of Chile and Argentina. This species thrives in moist environments characterized by dense vegetation, including alpine meadows and valleys near riverbanks, making it an integral part of these ecosystems.

Physical Characteristics:
The Otro Cerro Pericote is a small rodent, measuring approximately 12-15 cm in length, with a tail that is about the same length as its body. Its fur is typically a shade of brown or grey, providing excellent camouflage against the forest floor. Notable features include its large ears and long whiskers, which enhance its sensory perception in dense underbrush. The species shows a robust body shape and slightly pointed snout, typical of many species within the family Cricetidae.

Behavior:
Otro Cerro Pericote is primarily nocturnal, exhibiting increased activity during the night when it forages for food. This species is known for its agile climbing abilities and often constructs nests in low shrubbery. It is also social, often found in small groups, which helps with predator evasion—a behavior that is essential for its survival. Moreover, its ability to communicate via vocalizations plays a crucial role in maintaining group cohesion.

Diet:
The diet of Otro Cerro Pericote consists mainly of seeds, fruits, and roots, making it an important seed disperser within its habitat. It occasionally consumes insects and fungi, which provides a diverse nutrient intake. This omnivorous feeding habit not only sustains the species but also influences the availability of plant species within its ecosystem, further underlining its role in maintaining ecological balance.

Reproduction:
Otro Cerro Pericote has a breeding season that typically occurs in the spring and summer months, with females giving birth to litters of 3-6 young after a gestation period of approximately 25 days. Offspring are altricial at birth, requiring substantial care from the mother until they are weaned. Parental investment is critical for the survival of the young, and sibling interactions can be observed as they grow and prepare for independence.

Conservation Status:
The conservation status of Otro Cerro Pericote is currently classified as ‘Vulnerable’ due to habitat loss and fragmentation caused by agricultural expansion and urban development. Efforts are needed to protect their natural habitats to ensure the survival of this species.

Interesting Facts:
One fascinating aspect of Otro Cerro Pericote is its ability to adapt to varying environmental conditions, which allows it to occupy different niches within its habitat. Additionally, studies have shown that this species has a unique grooming behavior that helps prevent fur parasites, highlighting its adaptability and resilience.

Role in Ecosystem:
Otro Cerro Pericote plays a pivotal role in its ecosystem as a herbivore and seed disperser, which contributes to the health of plant communities in Andean forests. Its interactions with other species, such as predators and competing rodents, help to maintain biodiversity and ecological balance, showcasing its importance in sustaining the natural environment.
