Relatedness, trait evolution, and climatic niche divergence in mammalian island endemics

open access: yesOikos, Volume 2025, Issue 8, August 2025.
Island mammals have influenced ecological and evolutionary theory since Darwin, and many of them provide textbook examples of the dramatic morphological evolution that often occurs in island communities. However, patterns of evolution in the climatic niches of island mammals have yet to be fully explored.

Core promoter short tandem repeats as evolutionary switch codes for primate speciation [PDF]

open access: yes, 2015
Alteration in gene expression levels underlies many of the phenotypic differences across species. Because of their highly mutable nature, proximity to the +1 transcription start site (TSS), and the emerging evidence of functional impact on gene ...

Risk posed by the HPAI virus H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13, currently circulating in the US

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The emergence of highly pathogenic avian influenza (HPAI) A(H5N1), clade 2.3.4.4b, genotype B3.13 in U.S. dairy cattle marks a significant shift in the virus' host range and epidemiological profile. Infected cattle typically exhibit mild clinical signs, such as reduced milk production, mastitis and fever, with morbidity generally below 20% and

Down to earth: therian mammals became more terrestrial towards the end of the Cretaceous

open access: yesPalaeontology, Volume 68, Issue 2, March/April 2025.
Abstract The end Cretaceous extinctions had a profound effect on mammalian diversity, especially on metatherians (marsupials and their extinct relatives). Could mammalian substrate preference have influenced differential survival patterns? The plant fossil record shows changing angiosperm leaf anatomy during the last ten million years of the Cretaceous

Wildlife Pathogens and Zoonotic Disease Risk Assessment in Vietnam: A Wildlife Trade Hotspot

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Vietnam is a wildlife trade hotspot presenting multiple high‐risk interfaces for pathogen spillover from wildlife to humans. However, the zoonotic disease risk remains poorly characterized in the country and needs to be assessed to better inform policy dialog and legislative reforms.

Geographic range shifts do not erase the historic signal of speciation in mammals

open access: yes, 2015
Many evolutionary analyses assume that the positions of species geographic ranges are sufficiently phylogenetically conserved that current ranges reflect ancestral ranges and retain the historic signal of speciation.

Positive Selection of TLR2 and MyD88 Genes Provides Insights Into the Molecular Basis of Immunological Adaptation in Amphibians

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...
