Range-restricted upland taxa are prone to population bottlenecks and thus typically have
low genetic diversity, making them particularly vulnerable to environmental change. In this …

Insect flight loss is a repeated phenomenon in alpine habitats, where wing reduction is
thought to enhance local recruitment and increase fecundity. One predicted consequence of …

Recent genomic analyses have highlighted parallel divergence in response to ecological
gradients, but the extent to which altitude can underpin such repeated speciation remains …

Natural selection along elevational gradients has potential to drive predictable adaptations
across distinct lineages, but the extent of such repeated evolution remains poorly studied for …

The origin of the New Zealand “beech gap,” a low-diversity zone in the central South Island
corresponding with a disjunction in the distribution of many taxa, has been the focus of …

Aim Climate warming is causing extensive loss of glaciers in mountainous regions, yet our
understanding of how glacial recession influences evolutionary processes and genetic …

Much remains unknown about the genetic status and population connectivity of high-
elevation and high-latitude freshwater invertebrates, which often persist near snow and ice …

Comparative population genetic studies provide a powerful means for assessing the degree
to which evolutionary histories may be congruent among taxa while also highlighting the …

The evolution of flight is a key innovation that may enable the extreme diversification of
insects. Nonetheless, many species-rich, winged insect groups contain flightless lineages …

Most of arthropod biodiversity is unknown to science. For this reason, it has been unclear
whether insect communities around the world are dominated by the same or different taxa …
