Cells, 2021 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 ...

On the development of the chondrocranium and the histological anatomy of the head in perinatal stages of marsupial mammals [PDF]
, 2017 An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides ...

Marsupial Gut Microbiome [PDF]
Frontiers in Microbiology, 2020 The study of the gut microbiome in threatened wildlife species has enormous potential to improve conservation efforts and gain insights into host-microbe coevolution. Threatened species are often housed in captivity, and during this process undergo considerable changes to their gut microbiome.

Ecological selectivity and the evolution of mammalian substrate preference across the K–Pg boundary
Ecology and Evolution, 2021 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 ...

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

Retrotransposon silencing by DNA methylation can drive mammalian genomic imprinting [PDF]
, 2015 Among mammals, only eutherians and marsupials are viviparous and have genomic imprinting that leads to parent-of-origin-specific differential gene expression. We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (

Mechanisms of Choice in X-Chromosome Inactivation
Cells, 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.

Expansion of CORE-SINEs in the genome of the Tasmanian devil [PDF]
, 2012 Background: The genome of the carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii, Order: Dasyuromorphia), was sequenced in the hopes of finding a cure for or gaining a better understanding of the contagious devil facial tumor disease that ...
