The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]
, 2019 Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a

Revista Brasileira de Parasitologia VeterináriaToxoplasma gondii is a protozoan parasite that infects a large spectrum of warm-blooded animals, including humans. Small rodents and marsupials play an important role in the epidemiology of T. gondii because they are sources of infection for domestic and

Genetic Structure and Gene Flow in Eastern Grey Kangaroos in an Isolated Conservation Reserve
Diversity, 2021 Dispersal is a key process for population persistence, particularly in fragmented landscapes. Connectivity between habitat fragments can be easily estimated by quantifying gene flow among subpopulations. However, the focus in ecological research has been

Atlantic mammal traits: a dataset of morphological traits of mammals in the atlantic forest of south America [PDF]
, 2018 Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species.

The transcriptomic evolution of mammalian pregnancy:gene expression innovations in endometrial stromal fibroblasts [PDF]
, 2016 The endometrial stromal fibroblast (ESF) is a cell type present in the uterine lining of therian mammals. In the stem lineage of eutherian mammals, ESF acquired the ability to differentiate into decidual cells in order to allow embryo implantation.

Journal of General Virology, 1979 A virus-like particle was observed in two continuous cell lines derived from the marsupial Sminthopsis crassicaudata (Fat-tailed Dunnart). The development of the particle was similar to the development of D-type oncoviruses. Initially, a crescentof nucleoid material was observed near the nucleus in the region of the Golgi apparatus.

Characterization of extracellular spike waveforms recorded in wallaby primary visual cortex
Frontiers in Neuroscience, 2023 Extracellular recordings were made from 642 units in the primary visual cortex (V1) of a highly visual marsupial, the Tammar wallaby. The receptive field (RF) characteristics of the cells were objectively estimated using the non-linear input model (NIM),

Assessing the potential for intraguild predation among taxonomically disparate micro-carnivores: marsupials and arthropods [PDF]
Royal Society Open Science, 2018 Interspecific competition may occur when resources are limited, and is often most intense between animals in the same ecological guild. Intraguild predation (IGP) is a distinctive form of interference competition, where a dominant predator selectively ...
