Background: Insects comprise one of Earth's most diverse animal groups, but the adaptive capacity of most species, especially those with weak genetic structure, remains understudied. Psolodesmus mandarinus is an endemic damselfly in Taiwan, where its populations show latitudinal variation in wing traits despite limited genetic differentiation in mitochondrial and ribosomal sequences. We hypothesised that weak genome-wide structure may obscure the signals of local adaptation driven by environmental variation. To test this, we integrated genome-wide SNPs, phenotypic measurements, environmental associations, and species distribution models.
Results: Although genome-wide population structure was generally weak, pairwise FST values exceeded 0.35 between southeastern and northeastern populations, and genetic-environment association analyses identified outlier loci and individuals associated with environmental variables. Wing traits, particularly wing colours, exhibited a latitudinal divergence and exceeded expectations from neutral structure (PST >FST), indicating selection. Species distribution models showed ecological differentiation and predicted range expansion for clear-winged individuals but range contraction for dark-winged individuals under future climate scenarios.
Conclusion: Our findings demonstrate that phenotypic divergence can arise and persist under weak genetic structure, highlighting the evolutionary potential for local adaptation in structured environments even in species with high dispersal potential. An integrative framework provides essential insights for predicting biodiversity responses to environmental change and guiding climate-resilient conservation strategies.

Background: The Russian desman (Desmana moschata) is a critically endangered, elusive semi-aquatic mammal. While understanding its historical population dynamics is crucial for conservation, genomic data on its evolutionary and demographic history remain scarce.
Results: Here, we present a comprehensive whole-genome phylogenetic analysis of Desmana moschata within the Talpidae family, including heterozygosity assessments and inferred population size changes, as determined by PSMC and MSMC analyses. Our results demonstrate that, similar to its closest relative the Pyrenean desman (Galemys pyrenaicus), this species has undergone a long-term population decline preceding significant human influence. The phylogenetic component of our study involved a multigene analysis based on over 2,000 exons, producing a well-resolved, dated phylogeny of the Talpidae family at the tribal level.
Conclusions: Although anthropogenic factors have undoubtedly contributed to recent declines, our data reveal that the reduction in the desman population is primarily an ancient process driven by natural causes. This has resulted in persistent declines in both effective population size and geographic range and then subsequent evolutionary extinction of ancient taxa with limited adaptive capabilities. These findings lay the groundwork for future genomic conservation studies, incorporating expanded sampling and targeted investigation of specific genomic features.
