Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3397-3415, November 2026.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

Vicariant speciation resulting from biogeographic barriers in the Australian tropics: The case of the red‐cheeked dunnart (Sminthopsis virginiae)

open access: yesEcology and Evolution
Global biodiversity loss continues unabated, and in Australia, the rate of recent mammal extinctions is among the worst in the world. Meanwhile, the diversity among and within many endemic mammal species remains undescribed.

Fleas From the Northern Hairy‐Nosed Wombat and Other Mammalian Hosts of Australia

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT One of us (DKM) amassed a collection of 283 adult fleas (18 species) from donations by staff of the Queensland National Parks and Wildlife Service and other mammalogists, over 20 years (1967–87). Among this large collection were the first fleas to be found on three species of Australian mammals: (i) Lasiorhinus krefftii, the northern hairy ...

Enabling Complex Behavior by Simulating Marsupial Actions

open access: yes, 2006
Marsupial robotics is a field which requires a high initial investment prior to experiments. We present a new simulation tool used for marsupial actions, enabling research in the area of marsupial robotics.

Sit‐and‐Wait for the Agoutis: Dung Beetle Phoresy on Dasyprocta azarae in a Tropical Forest

open access: yesBiotropica, Volume 58, Issue 6, November 2026.
ABSTRACT We document the first case of phoresy by dung beetles with a rodent, involving Canthon (Goniocanthon) smaragdulus subviridis and agoutis (Dasyprocta azarae). Camera traps set in a tropical forest recorded 21 phoretic events, with agoutis carrying 1–6 beetles each. This behavior likely enhances how beetles locate fresh dung.

De novo transcriptome assembly and genome annotation of the fat-tailed dunnart (Sminthopsis crassicaudata)

open access: yesGigaByte
Marsupials exhibit distinctive modes of reproduction and early development that set them apart from their eutherian counterparts and render them invaluable for comparative studies.

The variability of giraffe skull morphology

open access: yesJournal of Anatomy, Volume 249, Issue 5, Page 1068-1086, November 2026.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Health and disease status of Australia's most critically endangered mammal the Gilbert's potoroo (Potorous gilbertii) [PDF]

open access: yes, 2008
The Gilbert's potoroo (Potorous gilbertii) is a small marsupial endemic to the Two Peoples Bay Nature Reserve in the south-west of Western Australia. The Gilbert's potoroo is classified as Australia's most critically endangered mammal (IUCN 2006) with ...

Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult
