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 ...

Accounting for molecular stochasticity in systematic revisions: species limits and phylogeny of Paroaria [PDF]

open access: yes, 2009
Different frameworks have been proposed for using molecular data in systematic revisions, but there is ongoing debate on their applicability, merits and shortcomings.

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.

Population structure of avian malaria parasites

open access: yesEcology and Evolution, 2019
The geographic distribution of genetic diversity in malaria parasite populations (Apicomplexa: Haemosporida) presumably influences local patterns of virulence and the evolution of host‐resistance, but little is known about population genetic structure in

Colonization and dispersal patterns of the invasive American brine shrimp Artemia franciscana (Branchiopoda: Anostraca) in the Mediterranean region [PDF]

open access: yes, 2013
Cysts of the brine shrimp Artemia franciscana are harvested from the Great Salt Lake (GSL) and San Francisco Bay (SFB) saltworks in the USA, and marketed worldwide to provide live food for aquaculture.

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 ...

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 ...

Detection, prevalence, and transmission of avian hematozoa in waterfowl at the Arctic/sub-Arctic interface: co-infections, viral interactions, and sources of variation [PDF]

open access: yes, 2016
Background The epidemiology of avian hematozoa at high latitudes is still not well understood, particularly in sub-Arctic and Arctic habitats, where information is limited regarding seasonality and range of transmission, co-infection dynamics with ...
