Marsupial and monotreme milk—a review of its nutrient and immune properties [PDF]
PeerJ, 2020 All mammals are characterized by the ability of females to produce milk. Marsupial (metatherian) and monotreme (prototherian) young are born in a highly altricial state and rely on their mother’s milk for the first part of their life.

Monotreme-specific conserved putative proteins derived from retroviral reverse transcriptase [PDF]
Virus Evolution, 2022 Endogenous retroviruses (ERVs) have played an essential role in the evolution of mammals. ERV-derived genes are reported in the therians, many of which are involved in placental development; however, the contribution of the ERV-derived genes in ...

Tracing Monotreme Venom Evolution in the Genomics Era
Toxins, 2014 The monotremes (platypuses and echidnas) represent one of only four extant venomous mammalian lineages. Until recently, monotreme venom was poorly understood.

The Evolution of Marsupial and Monotreme Chromosomes [PDF]
Cytogenetic and Genome Research, 2012 Marsupial and monotreme mammals fill an important gap in vertebrate phylogeny between reptile-mammal divergence 310 million years ago (mya) and the eutherian (placental) mammal radiation 105 mya. They possess many unique features including their distinctive chromosomes, which in marsupials are typically very large and well conserved between species. In

Identification and functional characterization of a novel monotreme- specific antibacterial protein expressed during lactation. [PDF]
PLoS ONE, 2013 Monotremes are the only oviparous mammals and exhibit a fascinating combination of reptilian and mammalian characters. They represent a component of synapsidal reproduction by laying shelled eggs which are incubated outside the mother's body.

Immunome database for marsupials and monotremes [PDF]
BMC Immunology, 2011 Background To understand the evolutionary origins of our own immune system, we need to characterise the immune system of our distant relatives, the marsupials and monotremes.

Applying a modified streamlined disease risk analysis framework to a platypus conservation translocation, with special consideration for the conservation of ecto- and endoparasites [PDF]
International Journal for Parasitology: Parasites and WildlifePlatypuses are the world's most evolutionarily distinct mammal and have several host-specific ecto- and endoparasites. With platypus populations declining, consideration should also be given to preserving these high conservation priority parasites ...

Targeted molecular screening for protozoan parasites in wild platypuses (Ornithorhynchus anatinus) and associated risk factors for infection [PDF]
International Journal for Parasitology: Parasites and WildlifeThe platypus (Ornithorhynchus anatinus) is a unique monotreme endemic to eastern Australia, yet little is known about the prevalence and impact of protozoan infections in wild populations. This study investigated the occurrence of protozoan parasites and

Hibernation in a monotreme, the echidna (Tachyglossus aculeatus) [PDF]
Comparative Biochemistry and Physiology Part A: Physiology, 1989 The body temperatures of five echidnas in Australia's Southern Alps were monitored by radio telemetry from February to December 1987. All five hibernated throughout the winter, showing very low body temperatures (4-9 degrees C, close to ambient) when torpid, compared with 28-33 degrees C in a typical day during the active season.

Therian origin of INSL3/RXFP2-driven testicular descent in mammals [PDF]
Frontiers in Cell and Developmental BiologyIntroduction: During early development in most male mammals the testes move from a position near the kidneys through the abdomen to eventually reside in the scrotum.
