Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity. [PDF]
ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.

Genetic origins and climate-induced erosion in economically important Asian walnuts. [PDF]
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Anomalous latitudinal gradients in parasitoid wasp diversity-Hotspots in regions with larger temperature range. [PDF]
Using the largest georeferenced molecular dataset for ichneumonoid parasitoid wasps, we implemented a macrogenetics approach to examine latitudinal patterns and predictors of intraspecific genetic diversity and explain the global distribution of genetic diversity in this group.

The frequency and importance of polyploidy in tropical rainforest tree radiations. [PDF]
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...
