East-West Genetic Differentiation in Musk Ducks (Biziura lobata) of Australia Suggests Late Pleistocene Divergence at the Nullarbor Plain [PDF]

open access: yes, 2010
Musk Ducks (Biziura lobata) are endemic to Australia and occur as two geographically isolated populations separated by the Nullarbor Plain, a vast arid region in southern Australia. We studied genetic variation in Musk Duck populations at coarse (eastern

The hitchhiker's guide to avian malaria [PDF]

open access: yes, 2006
The ecological mechanisms underlying the dispersal of parasites are poorly understood, which is of particular concern in view of currently emerging infectious diseases.

Detection of Vkorc1 single nucleotide polymorphisms indicates the presence of anticoagulant rodenticide resistance in Australia's introduced rats†

open access: yesPest Management Science, Volume 81, Issue 9, Page 5827-5834, September 2025.
Introduced rat species in Australia were tested for Vkorc1 gene mutations associated with anticoagulant rodenticide resistance. The widespread occurrence of Tyr25Phe suggests potential resistance is common in Rattus rattus. Image created with BioRender.com Abstract BACKGROUND Anticoagulant rodenticides (ARs) are used globally to manage pest rodent ...

Profound climatic effects on two East Asian black-throated tits (Ave: Aegithalidae), revealed by ecological niche models and phylogeographic analysis. [PDF]

open access: yesPLoS ONE, 2011
Although a number of studies have assessed the effects of geological and climatic changes on species distributions in East Asian, we still have limited knowledge of how these changes have impacted avian species in south-western and southern China.

Museomics and Salvaged Feathers Piece Together the Evolutionary History and Conservation Genomics of the Elusive, Critically Endangered Night Parrot (Pezoporus occidentalis)

open access: yesMolecular Ecology, Volume 34, Issue 18, September 2025.
ABSTRACT The Night Parrot is a critically endangered nocturnal bird of Australia's arid zone. The species was “lost” for most of the 20th century until its rediscovery in 1990. Extant populations are now known in eastern and western Australia, but the species has been extirpated from much of its historical range.

Evolutionary associations between sand seatrout (Cynoscion arenarius) and silver seatrout (C. nothus) inferred from morphological characters, mitochondrial DNA, and microsatellite markers [PDF]

open access: yes, 2009
The evolutionary associations between closely related fish species, both contemporary and historical, are frequently assessed by using molecular markers, such as microsatellites.

Extensive polymorphism and geographical variation at a positively selected MHC class II B gene of the lesser kestrel (Falco naumanni) [PDF]

open access: yes, 2008
Understanding the selective forces that shape genetic variation in natural populations remains a high priority in evolutionary biology. Genes at the major histocompatibility complex (MHC) have become excellent models for the investigation of adaptive ...

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

open access: yesAdvanced Science, Volume 12, Issue 29, August 7, 2025.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

Past hybridization between two East Asian long-tailed tits (Aegithalos bonvaloti and A. fuliginosus) [PDF]

open access: yes, 2014
Introduction: Incomplete lineage sorting and hybridization are two major nonexclusive causes of haplotype sharing between species. Distinguishing between these two processes is notoriously difficult as they can generate similar genetic signatures ...
