The University of Chicago Press. It has been argued that big-eared opossums are exclusively terrestrial and only go into trees to escape flooding, but other studies have shown that using proper techniques, big-eared opossums can be trapped or tracked in trees as frequently as on the ground.
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.

Lawrence, The Didelphix Society of Mammalogists, 47p. Scat sampling has identified several dietary items including rubbish consumed by animals living diedlphis urban areas.

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.
Classes de desenvolvimento em marsupiais: Marcondes provided inestimable technical and administrative help. The large sample size required for use of life tables is often the major hurdle against their use.
This article about a marsupial is a stub. As such, the name azarae has been abandoned. Captures may include only females, under the assumption ahrita all females are available for fertilization by the males, since reproduction, and thus demographic data, comes from the females STEARNS Big-eared opossum  Conservation status.
The latter may help seed dispersal. The population dynamics of D.

Mortality rate q x was highest in lactant and young, while lowest values were found for adults in most cohorts, since didelpis were also captured as senescent Fig.
Possible economic benefits may include ecotourism because of their abundance in tropical rainforests. Studies on Neotropical Fauna and Environment 36 2: Reproductive value increased to the third or fourth age classes, after which divelphis declined Fig. They are typically found in moister habitats Eisenberg and Redford From Wikipedia, the free encyclopedia.
