Cranial Anatomy of the Earliest Marsupials and the Origin of Opossums [PDF]
BackgroundThe early evolution of living marsupials is poorly understood in part because the early offshoots of this group are known almost exclusively from jaws and teeth.

Metagenomic analysis of fecal microbiomes reveals genetic potential for diverse hydrogen management strategies in marsupials [PDF]
Methane is an end product of plant biomass digestion by gut microbiota, though the amount produced and/or released varies between hosts. On a per-unit-of-feed basis, macropodid marsupials (e.g., kangaroos) have been reported to emit less methane than ...

Use of Tie-in Fixation and Modified Poliglecaprone-25 Suture Cerclages in a Complex Femoral Diaphysis Fracture in a Black-Eared Opossum (Didelphis aurita): Case Report [PDF]
A juvenile opossum was found after an episode of trauma caused by a vehicular collision. In the emergency care, vital parameters and changes related to the trauma were measured, and it was not possible to verify any changes, other than a crepitation in ...

Molecular evolution of vision-related genes may contribute to marsupial photic niche adaptations
Vision plays an essential role in the life of many animals. While most mammals are night-active (nocturnal), many have adapted to novel light environments. This includes diurnal (day-active) and crepuscular (twilight-active) species.

A review of small non-volant mammal species of the APA Gama e Cabeça de Veado was carried out, including new surveys in the "Estação Ecológica do Jardim Botânico" (EEJBB) and "Reserva Ecológica do Instituto Brasileiro de Geografia e Estatística ...

Males have evolved species-specifical sperm morphology and swimming patterns to adapt to different fertilization environments. In eutherians, only a small fraction of the sperm overcome the diverse obstacles in the female reproductive tract and ...

The Cerrado biome is one of the global hotspots of biodiversity, and non-volant small mammals represent a significant portion of Cerrado species richness (45%) and endemism (86%).

Ecological selectivity and the evolution of mammalian substrate preference across the K–Pg boundary
The Cretaceous–Paleogene (K–Pg) mass extinction 66 million years ago was characterized by a worldwide ecological catastrophe and rapid species turnover. Large‐scale devastation of forested environments resulting from the Chicxulub asteroid impact likely ...
