Species Description: Patton’s Atlantic Tree-rat

Common Name: Patton’s Atlantic Tree-rat
Scientific Name: Pattonomys sp.

Habitat

Patton’s Atlantic Tree-rat is primarily found in the coastal rainforests of eastern Brazil, particularly in the states of Bahia and Espírito Santo. These lush, tropical environments provide the necessary humidity and canopy coverage, allowing for a thriving population. The species typically inhabits humid lowland forests and can occasionally be spotted in secondary growth areas near rivers and streams.

Physical Characteristics

This medium-sized rodent weighs approximately 250-400 grams and measures 25-35 cm in length, including its tail. Patton’s Atlantic Tree-rat features a distinctive dark brown fur with lighter underparts, which offers effective camouflage in the forest understory. Notable features include large round ears, a long, bushy tail, and sharp incisors adapted for nut and seed consumption.

Behavior

Patton’s Atlantic Tree-rat exhibits primarily nocturnal behavior, becoming active during the night to forage for food and interact socially. These rodents are known for their agility in climbing trees, often found foraging on branches for fruits and seeds. They are also solitary creatures but will gather in small groups during the breeding season or when food is abundant.

Diet

The diet of Patton’s Atlantic Tree-rat consists mainly of fruits, nuts, and seeds, with a preference for tropical seeds from native plants. Their feeding habits are crucial for seed dispersal, which plays a significant role in maintaining the health of their habitat. This rodent also occasionally gnaws on tree bark and roots, contributing to its ecological impact.

Reproduction

Patton’s Atlantic Tree-rat has a breeding season that peaks during the rainy months, typically from October to December. Females give birth to 2-4 offspring after a gestation period of approximately 30-40 days. The young are weaned after about two months and reach maturity at around six months, quickly becoming independent.

Conservation Status
