Ultrasonographic features of the platypus abdomen via a limited left pre‐epipubic acoustic window from a series of 54 individuals

open access: yesAustralian Veterinary Journal, Volume 104, Issue 10, Page 653-660, October 2026.
Introduction There are notable differences between the platypus and common species of domestic mammal in the location and structure of some abdominal organs. The aim of this study was to detail the size, position and relative locations of organs in the left side of the platypus abdomen, to assist evidence‐based decision‐making in a clinical setting ...

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

open access: yesActa Zoologica, Volume 107, Issue 4, Page 460-469, October 2026.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Comparative Immunopathology of Toxoplasma gondii Natural Infections in Marmosets (Callithrix spp.) and Howler Monkeys (Alouatta spp.), Brazil

open access: yesJournal of Medical Primatology, Volume 55, Issue 5, October 2026.
ABSTRACT Introduction Neotropical primates (NTPs) present varying susceptibility to toxoplasmosis caused by Toxoplasma gondii, but their immunopathogenic responses remain poorly understood. Materials and Methods Local immune responses were characterized in the liver, spleen, and central nervous system (CNS) of 50 naturally infected NTPs (31 Callithrix ...

Secondary cartilage in the murine medial pterygoid plate has a critical role in the pathfinding of the tensor veli palatini

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 759-768, October 2026.
The development of the medial pterygoid plate (MPP) is followed in mouse embryos, highlighting its neural crest origin and complex development via both endochondral and membranous ossification. Using transgenic mice, the secondary cartilage of the MPP is shown to direct the path of the tensor veli palatini.

Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 847-864, October 2026.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

Genomic Vulnerability of a Threatened Possum in a Biodiversity and Climate Change Hotspot

open access: yesMolecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Spatial variation in the magnitude and pace of climate change impacts means some species will be more affected than others. This includes those occurring within global biodiversity hotspots, regions with exceptional concentrations of endemic species that have often been shaped by long‐term climatic stability.

Dental Complexity and Crown Relief Document Occlusal Wear Along the Tooth Row in West Indian Manatees

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Sirenians are a lineage of herbivorous marine mammals morphologically specialized for exploiting aquatic vegetation in shallow‐water habitats. In manatees (Trichechus), continuous horizontal tooth replacement may represent a solution for mitigating heavy dental wear incurred by a diet of abrasive plant material.
