Aim Quaternary climatic oscillations have profoundly shaped the genetic structure and geographic distributions of alpine biotas. Understanding how cold‐adapted taxa responded to past climatic shifts is essential for unravelling the processes shaping mountain biodiversity, yet cold‐adapted taxa may have followed divergent refugial histories. We compared two co‐distributed, high‐altitude endemic beetles to test two alternative b...

Repeated adaptation provides valuable insights into the predictability of evolution. Population history, selection and stochastic processes can concur to generate a continuum from distinct to highly parallel evolutionary trajectories across replicate populations. Yet, the role of genetic and environmental factors in shaping this continuum remains underexplored. We quantified repeated genetic adaptation in lizards that colonise...

Species identification and delimitation are particularly challenging for morphologically similar and geographically overlapping species, such as in the case of Western Palaearctic flea beetle species Psylliodes kiesenwetteri Kutschera, 1864 and Psylliodes ruffoi Leonardi, 1975. In this study, we implemented an integrative taxonomic approach based on a comprehensive geographic assessment of morphological and genetic variation,...

The recently published mitochondrial genome of the fingerprint oyster Alectryonella plicatula (Gmelin, 1791) with GenBank accession number MW143047 was resolved in an unexpected phylogenetic position, as sister to the Pacific cupped oyster Magallana gigas (Thunberg, 1793) and share with this species three typical gene duplications that represent robust synapomorphies of the Magallana clade. In this study, we verified the ident...
