“…In relation to P. frenatus, despite its omnivorous diet, it was observed to have a greater consumption of animal items, including the consumption of small vertebrates. These results are in accordance with Santori et al (1997), who reported the consumption of small vertebrates and invertebrates as the main items. The carnivorous tendency of this species based on experimental analysis of assimilation and digestive efficiency was suggested by Santori et al (1995).…”

“…In the Neotropics, some work has been done on food availability as correlated with habitat (Borchert and Hansen 1983;Martinez et al 1990;Bergallo and Magnusson 1999), demographic population (Fleming 1971;Gonza´lez et al 1989;Adler and Beatty 1997;Adler 1998;Bergallo and Magnusson 1999) and the reproductive cycle of those animals (Martino and Aguilera 1989;Bilenca et al 1992;Suarez 1994). In Brazil, the details of the diet of small mammals is limited to some studies (Leite et al 1996;Santori et al 1996Santori et al , 1997Talamoni et al 1999). One problem for diet analysis is that the diets of small mammals have often been studied by the analysis of faeces or stomach contents.…”

Diet of some species of Neotropical small mammals

Dietary analysis was performed to determine the variations in diet of some small neotropical species of mammals collected in seasonal areas of the cerrado (a savannah-like grassland) and semi-deciduous forest. Food items were determined based on the analysis of stomach contents of 126 animals (one didelphid and five sigmodontine rodent species). Most species presented herbivorous-omnivorous habits, with a preference for the vegetative parts of plants. Akodon montensis Thomas (1913) was the most abundant species in the forest area and demonstrated a uniform consumption of animal and vegetal items through the year, and contained 65.7% plant material in its diet. Necromys lasiurus (Lund, 1841) was the most abundant in the cerrado with 72.6% of vegetation in its diet, but showed a high consumption of animal items during the rainy season. Oligoryzomys nigripes (Olfers, 1818) contained 95.1% of plant material, while Oxymycterus delator (Thomas, 1903) consumed 61.6% invertebrates, mainly insects. The didelphid Philander frenatus (Olfers, 1818) consumed invertebrates (47.7%), small vertebrates (7.3%) and plant material (44.9%).

“…It occurs in tropical and subtropical forests, including secondary-growth forests, riparian forests, and also in pasture areas and near streams (Hershkovitz 1997;Santori et al 1997;CastroArellano et al 2000;Massoia et al 2000). Santori et al (1995) reported that P. opossum is predominantly carnivorous, and can live on a diet solely based on meat, provided water is available, or on an omnivorous diet with no water available.…”

In the last few years, studies about climate successions in Rio Grande do Sul State (southern Brazil) during the Quaternary increased significantly, mostly due to palynological studies. The knowledge about Quaternary small mammals from Rio Grande do Sul is very poor. However, among the results obtained by archeological research there is an interesting collection of small mammals exhumated from rock shelter deposits. Here we describe the marsupial fauna found in two sites: Garivaldino and Sanga˜o. Both sites are located at the boundary between two large Neotropical subregions, Chaco and Parana. Sediments from these two sites are from the early, middle, and part of the late Holocene. Additionally, we discuss paleobiogeographic, paleoenvironmental, and paleoclimatic aspects, on the basis of the seven taxa recorded: Gracilinanus microtarsus, G. agilis, Monodelphis americana, Thylamys velutinus, Thylamys cf. T. velutinus, Philander opossum, and Didelphis sp. Paleoenvironmental aspects inferred for both sites are consistent: the emergence of typical elements of the current Parana biogeographic subregion was probably established by the end of the early Holocene or the beginning of the middle Holocene. Conclusions are also coherent with the results previously obtained from palynological sequences in these same localities. The micro-marsupials sequence suggests that the environmental changes were not abrupt but gradual during the Holocene in Rio Grande do Sul State.

“…1), occur in lowland tropical and subtropical forests from Mexico to northern Argentina. 4 Closely related to other large didelphids with 22 chromosomes (tribe Didelphini: Chironectes, Didelphis, and Lutreolina), species of Philander are scansorial predators that eat a wide variety of invertebrates, small vertebrates, and fallen fruit (Charles-Dominique et al, 1981;Santori et al, 1997;Cáceres, 2004;Ceotto et al, 2009;Macedo et al, 2010). Because they are not reluctant to enter baited traps, species of Philander are abundant in museum collections, but their taxonomy has long been controversial.…”

This is the first installment of a revision of the didelphid marsupial genus Philander, commonly known as gray four-eyed opossums. Although abundant and widespread in lowland tropical forests from southern Mexico to northern Argentina, species of Philander are not well understood taxonomically, and the current literature includes many examples of conflicting species definitions and nomenclatural usage. Our revision is based on coalescent analyses of mitochondrial gene sequences, phylogenetic analyses of mitochondrial and nuclear genes, morphometric analyses, and firsthand examination of relevant type material. Based on these results, we provisionally recognize eight species, of which three are formally treated in this report: P. quica (Temminck, 1824), an Atlantic Forest endemic formerly known as P. frenatus (Olfers, 1818); P. canus (Osgood, 1913), a widespread species formerly treated as a synonym or subspecies of P. opossum (Linnaeus, 1758); and P. pebas, a new species endemic to Amazonia. The remaining, possibly valid, species of Philander can be allocated to two clades. The first is a cis-Andean complex that includes P. andersoni (Osgood, 1913); P. mcilhennyi Gardner and Patton, 1972; and P. opossum. The second is a transAndean complex that includes P. melanurus (Thomas, 1899) and P. pallidus (Allen, 1901). Among other nomenclatural acts, we designate a neotype for the long-problematic nominal taxon Didelphis superciliaris Olfers, 1818, and (in an appendix coauthored by Renate Angermann), we establish that Olfers' coeval binomen D. frenata is based on an eastern Amazonian type and is a junior synonym of P. opossum.
