Aparato trófico e variação nos hábitos alimentares de Philander opossum e Didelphis aurita (Didelphimorphia, Didelphidae)
… on food habits of Philander opossum and Didelphis aurita was tested. Were studied the diet in the field, food preference in laboratory, and their relationships with morfofisiological traits of trophic apparatus. Both marsupiais feed on invertebrates, small vertebrates and fruits. …

Aspectos da morfologia do intestino grosso do gambá Didelphis aurita (Wied-Neuwied, 1826) com ênfase nas células enteroendócrinas
O aparelho digestório possui função crucial no controle da homeostase energética, sendo esse mecanismo regulador atribuído, em parte, às células enteroendócrinas. Estas células representam a maior população de células produtoras de hormônios do organismo de mamíferos eutérios e atuam no controle da …

Estudo do desenvolvimento extra-uterino de Didelphis aurita Wied, 1826, em cativeiro: investigação de critérios para estimativa de idade
The growth and development of 37 litters of Didelphis aurita were studied in order to establish a method for age estimation. The sample included 11 litters of captive females and 26 litters captured as pouch young in the State of Rio de Janeiro, Brazil, which were subsequently reared in captivity. …

Ontogeny of the temporomandibular joint and middle ear of the Virginia opossum (Didelphis virginiana) and their implications for mammalian cranial evolution
… untested. Ontogeny of the Virginia opossum (Didelphis virginiana) TMJ resembles the evolutionary trajectory of mammalian jaw and ear bones, making it a useful model to study soft tissue development. We explored the soft tissue connections between the TMJ, middle ear, and jaw musculature in a …

The Lyme Disease Spirochete, <i>Borrelia burgdorferi</i>, in Tick Species Collected from Raccoons (<i>Procyon lotor</i>) and Opossums (<i>Didelphis virginiana</i>) Trapped in the Warren and Barren Counties of South Central Kentucky
The incidence of tick-borne zoonoses such as Ehrlichiosis, Rocky Mountain Spotted Fever, and Lyme disease has steadily increased in the southeastern United States in recent years. According to the Centers for Disease Control and Prevention (CDC), the southeastern states accounted for 1,200 of the …

Microhabitats de uma comunidade de pequenos mamíferos na restinga de Barra de Maricá, RJ
… Akodon sp. do group cursor, Proechimys iheringi, Didelphis aurita, Sphiggurus insidiosus e Rattus rattus in two distinct mesohabitats: marshy grassland and "restinga" forest. Sixteen variables were measured for each of the 100 capture sites studied from January to October, 1986. Six variables, of …

Relações filogenéticas da subfamília Didelphinae: padrões de variação da morfologia crânio-dentária (Marsupialia: Didelphidae)
… the large didelphids (Lutreolina (Chironectes (Didelphis, Philander))), but the phylogenetic relationships between these branches are still unclear. Furthermore, the genus Metachirus showed an ambiguous position in relation to these two main clades. These results corroborate the monophyly of the …

Effects of Road Characteristics, Land Cover, and Topography on Roadkill Patterns Across a Rural-Urban Gradient in Southwest Virginia
… were tree squirrels (Sciurus sp.), opossums (Didelphis virginiana), striped skunks (Mephitus mephitis), and raccoons (Procyon lotor). I found three roadkill hotspots, all along a major highway, and a high frequency of roadkill in spring, autumn, and early winter. High posted speed limits, the …
