| Urban forests are usually isolated and highly disturbed, however they are important shelters for tolerant animal species. Their food habits expose the different ecological roles these animals perform in the habitat. We analyzed the contribution of Didelphis albiventris Lund (1840), as a seed disperser, to the vegetation renewal of an urban forest fragment, describing its frugivorous diet and testing the viability of ingested seeds. Both male and female of white-eared opossum included a vast variety of items in their diet, mainly invertebrates and fruits. Fruits were consumed during all year round and seasonality was not observed. The majority of consumed fruits was from pioneer plant species, which is common in disturbed areas, in accordance to the... |

| Didelphis albiventris is a well-known and common marsupial. Due to its high adaptability, this very widespread generalist species occurs under various environmental conditions, this even including protected regions and disturbed urban areas. We studied a 653 bp fragment of cytochrome oxidase c (COI) from 93 biological samples from seven Brazilian localities, with linear distances ranging between 58 and about 1800 km to analyze the effects of geographic distances on variability and genetic differentiation. The haplotype network presented nine haplotypes and two genetic clusters compatible with the two most distant geographic areas of the states of Minas Gerais, in the southeast, and Rio Grande do Sul, in the extreme south. As each cluster was characterized... |

| El objetivo de este trabajo fue obtener parámetros hematológicos en poblaciones silvestres de comadreja overa Didelphis albiventris de la región centro de la Argentina. Se capturaron 39 individuos, a todos ellos se les realizó un recuento total y diferencial de células sanguíneas. Los valores promedio (± desvío estándar) obtenidos fueron: eritrocitos 5,01 (±2,4) × 10(6)µL-1; leucocitos 27.097 (±14.313) µL-1; neutrófilos 7.600 (±7.097) µL-1 (incluye inmaduros, 794 (±2.738) µL-1); linfocitos 13.110 (±7.541) µL-1; basófilos 1.218 (±1.441) µL-1; eosinófilos 1.983 (±2.458) µL-1; y monocitos 2.321 (±2.818) µL-1. La existencia de asociaciones entre estos parámetros y factores ambientales (estación) y del animal (sexo y edad) fue evaluada mediante regresión lineal... |

| Tetratrichomonas didelphidis (Hegner and Ratcliffe 1927) Andersen and Reilly 1965 is a flagellate protozoan from the intestine, cecum and colon of Didelphis marsupialis Linnaeus, 1758. The prevalence of T. didelphidis in opossums D. albiventris was studied in the Botanical Garden, Porto Alegre City in the southernmost Brazilian State, Rio Grande do Sul, Brazil. T. didelphidi was found in seven of eight cultures of swabbed rectums, representing a prevalence of 87.5% in D. albiventris. In the present investigation it was observed that the T. didelphidis found in the intestine content of D. albiventris had the same morphological characteristics as those previously described by other authors in the D. marsupialis, being the same protozoan species in both host... |
