Landscape‐Driven Isolation Among, but High Genetic Diversity Within, Peripheral Populations of a Threatened Frog

Diversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim Many amphibians are experiencing declines, which are exacerbated for populations near range edges. To inform conservation strategies, we sampled sites of Blanchard's Cricket Frog (Acris blanchardi) at the northern periphery of their range to determine if modern declines are associated with genetic factors, delineate management units, and ...

Leveraging Knowledge of Traditional Italian Maize Landrace Diversity to Identify Signals of Local Adaptation

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Climate change is the greatest challenge to modern agriculture. It significantly impacts agricultural systems through an increased frequency and intensity of extreme environmental events. Maize, a vital crop for global food security, is particularly vulnerable to these changes, highlighting the urgent need to develop resilient varieties.

Genetic Diversity, Population Structure and Differentiation of Farmed and Wild African Catfish (Clarias gariepinus) in Nigeria

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT The African catfish (Clarias gariepinus) is a commercially important species, for both fisheries and aquaculture, and is now the most commonly farmed fish in sub‐Saharan Africa. However, knowledge about the genetic diversity and population structure of natural and farmed populations, which is crucial for effective conservation and sustainable ...

Glacial Legacies—How Refugial Dynamics Shaped the Evolution of the Alpine Endemic Bush‐Cricket Anonconotus italoaustriacus

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Mountain ranges like the European Alps harbour large endemic biodiversity shaped by Pleistocene climatic oscillations. The flightless bush‐cricket Anonconotus italoaustriacus, endemic to the Southern Limestone Alps (SLA) and the eastern Central Alps (CA), provides an ideal model to study the evolutionary and refugial dynamics of endemic alpine

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Population Genomics of a Rare and a Common Wood–Inhabiting Fungal Species Across Europe

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Many species have become threatened during the Anthropocene, requiring conservation strategies based on biological evidence. Wood‐inhabiting fungi face multiple threats due to a complex interplay of a short lifespan, removal of dead wood as a resource and climate change.
