Conservation of Marsupials and Monotremes

open access: yes, 2015
The history and current status of conservation of marsupials and monotremes is a mixture of exploitation, neglect and now for some species astounding conservation efforts.

Understanding mammal avoidance of human settlements

open access: yesJournal of Animal Ecology, EarlyView.
Terrestrial mammals often avoid human settlements, but is this a result of human activity around buildings or the built infrastructure per se? Using data on animal movement before and during the COVID‐19 lockdowns, this paper disentangles these effects, showing how changes in human mobility affect animals' avoidance of buildings. Abstract Anthropogenic

Comparative morphology of the internal nasal skeleton of adult marsupials based on X-ray computed tomography. (Bulletin of the American Museum of Natural History, no. 365)

open access: yes, 2012
91 p. : ill. (some col.) ; 26 cm.The internal skeleton of the nasal cavity is sporadically and often incompletely described for many marsupial species and mammals in general.

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

open access: yesIntegrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Functional morphology of the forelimb of living and extinct tree-kangaroos (Marsupialia: Macropodidae)

open access: yes, 2011
Tree-kangaroos are a unique group of arboreal marsupials that evolved from terrestrial ancestors. The recent discovery of well-preserved specimens of extinct tree-kangaroo species (genus Bohra) within Pleistocene cave deposits of south-central Australia ...

A large carnivorous mammal from the Late Cretaceous and the North American origin of marsupials

open access: yesNature Communications, 2016
The early fossil record of metatherian mammals, the group including marsupials, is limited. Here, Wilson and colleagues describe a fossil skull of the Late Cretaceous metatherianDidelphodon vorax, providing insight into the ecology of this species as ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Mammalian limb morphology: the role of the crawl in determining marsupial limb integration, development, and evolution

open access: yes, 2011
Marsupials and eutherians, though closely related sister taxa, differ greatly in the variety of morphologies found within their groups. This inequality has largely been argued to be due to the reproductive differences.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Species Distribution Models Reveal the Resilience of Protected Areas for Conserving an Endemic Amazonian Canid

open access: yesAnimal Conservation, EarlyView.
This graphical abstract illustrates the impacts of climate change on the distribution of the Amazon‐endemic canid Atelocynus microtis, highlighting projected habitat loss under future scenarios (SSP2–4.5 and SSP5–8.5). Despite substantial reductions in suitable habitat, a significant proportion remains within Protected Areas, emphasizing their critical
