Cranial Anatomy of the Earliest Marsupials and the Origin of Opossums [PDF]

open access: yesPLoS ONE, 2009
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]

open access: yesmSystems
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 ...

Postnatal and Adult Neurogenesis in Mammals, Including Marsupials

open access: yesCells, 2022
In mammals, neurogenesis occurs during both embryonic and postnatal development. In eutherians, most brain structures develop embryonically; conversely, in marsupials, a number of brain structures develop after birth.

Patterns of ontogenetic evolution across extant marsupials reflect different allometric pathways to ecomorphological diversity

open access: yesNature Communications, 2023
The relatively high level of morphological diversity in Australasian marsupials compared to that observed among American marsupials remains poorly understood.

Habitat Heterogeneity and Geographic Location as Major Drivers of Cerrado Small Mammal Diversity Across Multiple Spatial Scales

open access: yesFrontiers in Ecology and Evolution, 2022
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%).

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]

open access: yesIranian Journal of Veterinary Surgery, 2022
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 ...

Litter size and reproductive condition of small mammals in southern Goiás, Brazil

open access: yesMammalogy Notes, 2021
Litter size and reproductive conditions are important in natural history. However, this information is scarce in scientific literature. Here, we presented litter size data for eight small mammal species (four marsupials and four rodents) and investigated

Mechanisms of Choice in X-Chromosome Inactivation

open access: yesCells, 2022
Early in development, placental and marsupial mammals harbouring at least two X chromosomes per nucleus are faced with a choice that affects the rest of their lives: which of those X chromosomes to transcriptionally inactivate.

Recent aspects on epidemiology, clinical disease, and genetic diversity of Toxoplasma gondii infections in Australasian marsupials

open access: yesParasites & Vectors, 2021
Background Toxoplasma gondii infections are common in humans and animals worldwide. Among all intermediate hosts of T. gondii, captive marsupials from Australia and New Zealand are highly susceptible to clinical toxoplasmosis.

A Hollow Argument: Understory Vegetation and Disturbance Determine Abundance of Hollow-Dependent Mammals in an Australian Tropical Savanna

open access: yesFrontiers in Ecology and Evolution, 2021
Native mammals are suffering widespread and ongoing population declines across northern Australia. These declines are likely driven by multiple, interacting factors including altered fire regimes, predation by feral cats, and grazing by feral herbivores.
