Gloger's Rule or Historical Conjecture? Tests in Mammals. [PDF]

Ecol Evol
Ecogeographical rules for animal coloration include Gloger's rule, which states that homeotherms are darker at lower latitudes; however, 19th‐century naturalists observed that animals are more colourful in the tropics. We investigated these ideas across the head, torso, legs and tail regions of 2726 species of terrestrial mammals using phylogenetic ...

A suture in time: The ontogeny of cranial suture morphology in mammals. [PDF]

J Anat
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

Sarcophilus harrisii (Dasyuromorphia: Dasyuridae) [PDF]

Mammalian Species, 2017
The Tasmanian devil, Sarcophilus harrisii (Boitard, 1842), the largest surviving marsupial carnivore, is endemic to Tasmania. The size of a small stocky dog, with males weighing 9 kg and females 6 kg, S. harrisii is a scavenger of large mammals and opportunistic predator of vertebrates.

Modelling marsupial mastication: The biomechanical bite model of the Linnaeus's mouse opossum Marmosa murina (Marsupialia, Didelphidae). [PDF]

J Anat
The marsupial masticatory apparatus has rarely been studied until recently, mainly in Australasian species. We therefore reconstructed the maximum bite forces of the South American Linnaeus's mouse opossum Marmosa murina using in vivo bites, specimen dissections, and 3D static equilibrium of the jaw muscles.

Dental topographic and three‐dimensional geometric morphometric analysis of carnassialization in different clades of carnivorous mammals ( Dasyuromorphia, Carnivora, Hyaenodonta ) [PDF]

Journal of Morphology, 2021
Abstract The evolution of carnassial teeth in mammals, especially in the Carnivora, has been subject of many morphometric and some dental topographic studies. Here, we use a combination of dental topographic analysis (Dirichlet normal energy) and 3D geometric morphometrics of less and high carnassialized lower teeth of carnivoran ...

Systematics, biogeography and ancestral state of the Australian marsupial genus Antechinus (Dasyuromorphia: Dasyuridae) [PDF]

Zoological Journal of the Linnean Society, 2019
Since 2012 the number of recognized taxa in the Australian carnivorous marsupial genus Antechinus has increased from 10 to 15 species. The systematic relationships among these species and others in the genus are not well resolved. We undertook the first comprehensive, molecular systematic analysis of the genus, incorporating all known species and ...

Breeding fat-tailed dunnarts (Sminthopsis crassicaudata) in captivity: Revised practices to minimize stress whilst maintaining considerations of wild biology. [PDF]

Dev Dyn
Abstract Background The fat‐tailed dunnart is a small dasyurid marsupial which is emerging as a robust laboratory model for conservation, developmental, and reproductive biology research. While these marsupials present extremely valuable models, housing non‐domesticated animals in captivity can present a wide range of potential stressors for the ...

Drivers of habitat availability for terrestrial mammals: Unravelling the role of livestock, land conversion and intrinsic traits in the past 50 years

Global Change Biology, Volume 29, Issue 24, Page 6900-6911, December 2023., 2023
This study investigates the impact of habitat degradation on terrestrial mammal species. By comparing historic and current distribution maps for 475 species, we found that 59% of them have less available habitat in their lost ranges, suggesting habitat loss contributed to range declines.

Thermal, Metabolic, and Hygric Physiology of the Little Red Kaluta,Dasykaluta rosamondae(Dasyuromorphia: Dasyuridae) [PDF]

Journal of Mammalogy, 2009
The little red kaluta (Dasykaluta rosamondae) is a small, insectivorous–carnivorous dasyurid marsupial found in arid spinifex grasslands of northwestern Australia. Kalutas resemble other dasyurids in many aspects of their physiology. Body temperature (Tb; 33.5uC; 1.5uC lower than predicted), wet thermal conductance (1.6 J g 21 h 21 uC 21 ;9 1 % of ...

Myrmecobius fasciatus (Dasyuromorphia: Myrmecobiidae) [PDF]

Mammalian Species, 2011
Myrmecobius fasciatus Waterhouse, 1836, is a small to medium-sized dasyuromorph marsupial known as the numbat. M. fasciatus is unusual among marsupials in that it is diurnal and feeds exclusively on termites, and it has a number of characteristic adaptations associated with this specialized niche. M.
