Impacts of Quaternary Climate History on the Biogeography of Specialized Butterflies in the Great Basin of North America

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Dramatic Quaternary climate fluctuations impacted the evolutionary history and contemporary biogeography of many residents of the Great Basin Desert of western North America. This study investigates the historical biogeographic processes that shaped the contemporary distribution of genetic variation in a polytypic group of specialized ...

Range‐Wide Genetic Population Structure and Environmental Adaptation in the Eastern Oyster (Crassostrea virginica) Provides Insight for Aquaculture

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT Selective breeding in aquaculture is necessary to establish food security and meet demand for sustainably produced protein. An informed selective breeding program requires understanding how population structure, environmental adaptation, and human activities shape natural genetic variation in wild conspecifics.

Divergent Thermal Reaction Norms of the Spontaneous Mutation Rate Among Populations of Chironomus riparius

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT The germline mutation rate μ is a fundamental evolutionary parameter, yet its plasticity in response to environmental factors, particularly temperature, remains poorly understood. While often modelled as a species‐specific constant, we tested whether μ evolves in response to local thermal regimes.

Multiple Eurasian Origins and Admixture Shaped the Genomic Legacy of the House Mouse Invasion in Africa

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Commensal mammals offer unique opportunities to study how human‐mediated dispersal, admixture, and secondary contact shape genomic variation during range expansion, yet for one of the most successful invasive commensals globally, the western house mouse Mus musculus domesticus, invasion dynamics across Africa remain largely unexplored.

Over‐Representation of Sperm‐Associated Deleterious Mutations Across Wild and Ex Situ Cheetah (Acinonyx jubatus) Populations

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT As purifying selection becomes less effective and inbreeding increases, small populations frequently develop an increased load of genome‐wide deleterious mutations. Reflecting this pattern, deleterious mutations in genes associated with fertility and immunity have previously been identified in the cheetah (Acinonyx jubatus), which has had a ...

Inbreeding in a Fission–Fusion Equid Decreases Following an Increase in the Number and Redistribution of Water Sources

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Social structures and habitat configuration influence inbreeding in wild populations. In harem‐forming, female‐defence polygynous equids, social organization promotes inbreeding avoidance, but this has not been studied in fission–fusion, resource‐defence equid species.
