Weaning generally occurs at the end of the rainy season, while food is still available for the young.

Auruta body mass of Didelphis aurita ranges from grams. In the case of big-eared opossums, the breeding season coincides with the wet season, when fruit is most abundant. Heterakoidea Skrjabin and Schikobalova,are widely distributed didlphis the Americas.

Big-eared opossums Didelphis aurita are Neotropical marsupials found along the Atlantic coast of Brazil to northeastern Argentina and southeastern Paraguay. Plant Ecology 1: The cohort was not analyzed because many were still alive. Fecundity rate increased from subadults to adults, where it reached its maximum Fig.

Females were used for life table construction and only females that were marked while young and still within the pouch were used, comprising eight cohorts: The ears are black and the tail is furred at the base as long as the hind leg, with black and white parts nearly of equal length, or sometimes the black parts being longer Emmons Loretto provided valuable observation on earlier versions aueita the manuscript.

They are mainly terrestrial, but their relatively long forelimbs and claws allow them to easily climb trees. The grids vary in distance from the highway: Each cohort began in August, the month when females began to be captured with young in the pouch see results.

Generation time for the cohort was atypical and almost as twice as high compared to the preceding and following years. Since birth dates vary along eidelphis season and litters may be produced at the beginning or end of the breeding season, this will influence the generation time among cohorts.
