Geographic range shifts do not erase the historic signal of speciation in mammals

open access: yes, 2015
Many evolutionary analyses assume that the positions of species geographic ranges are sufficiently phylogenetically conserved that current ranges reflect ancestral ranges and retain the historic signal of speciation.

Embryology of the fat‐tailed dunnart (Sminthopsis crassicaudata): A marsupial model for comparative mammalian developmental and evolutionary biology

open access: yesDevelopmental Dynamics, Volume 254, Issue 2, Page 142-157, February 2025.
Abstract Background Marsupials are a diverse and unique group of mammals, but remain underutilized in developmental biology studies, hindering our understanding of mammalian diversity. This study focuses on establishing the fat‐tailed dunnart (Sminthopsis crassicaudata) as an emerging laboratory model, providing reproductive monitoring methods and a ...

An emerging consensus in the evolution, phylogeny, and systematics of marsupials and their fossil relatives (Metatheria) [PDF]

open access: yes, 2019
Marsupials and their fossil relatives, which collectively comprise Metatheria, have been of scientific interest for centuries, with many aspects of their evolution and systematics subject to intense research and debate.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Petrosal and Inner Ear of the Thylacine, Thylacinus cynocephalus (Harris, 1808) (Mammalia, Marsupialia, Dasyuromorphia)

open access: yesAnnals of Carnegie Museum
The petrosal and inner ear are described for the thylacine, Thylacinus cynocephalus (Harris, 1808), based on µCT datasets. Comparisons are made with a sample of six extant marsupials, also from µCT datasets: the didelphid Monodelphis sp. (short-tailed opossum), the notoryctid Notoryctes caurinus Thomas, 1920 (northern marsupial mole or kakarratul), the

A note on detection of the Common Dunnart Sminthopsis murina (Dasyuromorphia: Dasyuridae) using artificial shelter objects as a survey technique [PDF]

open access: yesAustralian Zoologist, 2016
The widespread Common Dunnart Sminthopsis murina is typically only infrequently found during trapping studies. Pitfall trapping is generally considered a more reliable trapping method for dunnarts than Elliott-type box traps, but is often time consuming and labour-intensive. This short paper documents incidental records of S.

Phylogenetic approaches for studying competition in mammals

open access: yes, 2009
Interspecific competition is often proposed to shape mammalian evolution. Many studies use trait and distribution data on extant species, but this ignores temporal aspects of competition.

Sexual selection of protamine 1 in mammals [PDF]

open access: yes, 2015
Protamines have a crucial role in male fertility. They are involved in sperm chromatin packaging and influence the shape of the sperm head and, hence, are important for sperm performance.

Mammal coloration as a social signal

open access: yesJournal of Zoology, Volume 323, Issue 2, Page 114-128, June 2024.
Otherwise apparently cryptic mammals often have conspicuous patches of colour on distal regions of their body, possibly for signalling. To investigate ideas about communication within sociosexual contexts, we used a comparative dataset for 2726 terrestrial mammals to match the coloration and patterning of distal body areas (head, chest, rump, and tail)

What we (do not) know about mammal coronavirus and general virus? Using bibliometric information to identify neglected taxonomic groups and potential viral reservoirs of zoonotic importance [PDF]

open access: yes, 2020
The COVID-19 pandemic is currently advancing in the world and has killed more people than other recent coronavirus outbreaks like SARS and MERS together.
