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

Acta Zoologica, EarlyView.
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.

Determining the efficacy of camera traps, live capture traps, and detection dogs for locating cryptic small mammal species

Ecology and Evolution, 2020
Metal box (e.g., Elliott, Sherman) traps and remote cameras are two of the most commonly employed methods presently used to survey terrestrial mammals. However, their relative efficacy at accurately detecting cryptic small mammals has not been adequately

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Host Abundance Predicts Interactive Roles in Neotropical Bat–Bat Fly Interactions

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We analyzed the influence of bat functional traits on their importance as hosts in bat–bat fly networks. Our results indicate that bat abundance is the main driver for host importance in Neotropical bat–bat fly interactions. ABSTRACT Host functional traits are known to shape host‐parasite interactions across multiple taxa.

qPCR‐Based Environmental DNA (eDNA) Detection of Cryptic Arboreal Species Interaction With Artificial Habitat Structures

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Through integrated in silico design, in vitro optimization, and in situ validation, we developed two probe‐based qPCR assays to detect cryptic phascogales from artificial habitat structures. This provides a robust, noninvasive tool to assist in evaluating fauna in managed landscapes.

Reviving the Paris Thylacines

Museum & Society
As we grapple with human impact on the environment in the period now referred to as the Anthropocene, natural history collections are accruing new meaning. Nowhere is this more relevant than in relation to the display of extinct species.

Host–Parasite Interaction Networks of Helminths of Sigmodontine Rodents in Two Different Areas of the Brazilian Atlantic Forest

Ecological Research, Volume 41, Issue 3, May 2026.
Two helminth‐rodent networks were analyzed for two distinct areas. Network modularity, nestedness, and degree of specialization were calculated for each network. Higher network modularity than nestedness and high network specialization were observed in both networks, suggesting functional and/or taxonomic specialization between helminth species and ...

Multiple Paternity, Mate Choice and Siring Success During Drought: Implications for a Semelparous Marsupial

Diversity
Multiple paternity in litters and a female’s choice of mate can significantly influence siring success and the success and survival of offspring. In captive agile antechinus (Antechinus agilis), a small, carnivorous marsupial that exhibits obligate ...

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, Volume 248, Issue 5, Page 873-887, May 2026.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Can remote infrared cameras be used to differentiate small, sympatric mammal species? A case study of the black-tailed dusky antechinus, Antechinus arktos and co-occurring small mammals in southeast Queensland, Australia.

PLoS ONE, 2017
The black-tailed dusky antechinus (Antechinus arktos) is an endangered, small carnivorous marsupial endemic to Australia, which occurs at low population density along with abundant sympatric populations of other small mammals: Antechinus stuartii, Rattus
