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 ...

Meiotic dynamics in a unique Australian marsupial provide new insights into the evolution of neo-sex chromosomes in the early stages of differentiation [PDF]

open access: yesFrontiers in Cell and Developmental Biology
Understanding the origin and fate of sex chromosomes has been one of the most intriguing questions in biology. In therian (marsupial and eutherian) mammals, most species are characterized by a heteromorphic XX female XY male sex chromosome system.

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 ...

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.

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.

High Trypanosoma spp. diversity is maintained by bats and triatomines in Espírito Santo state, Brazil [PDF]

open access: yes, 2017
The aim of this study was to reevaluate the ecology of an area in the Atlantic Forest, southeast Brazil, where Chagas disease (CD) has been found to occur.

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.

Evolutionary transcriptomics implicates new genes and pathways in human pregnancy and adverse pregnancy outcomes

open access: yeseLife, 2021
Evolutionary changes in the anatomy and physiology of the female reproductive system underlie the origins and diversification of pregnancy in Eutherian (‘placental’) mammals.

Molecular evolution of vision-related genes may contribute to marsupial photic niche adaptations

open access: yesFrontiers in Ecology and Evolution, 2022
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.

Conservation units in the core area of the Cerrado domain: an overview on the small nonvolant mammals (Rodentia and Didelphimorphia)

open access: yesHeringeriana, 2015
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 ...
