Aim The evolution of montane species provides critical insights into the drivers of adaptation and diversification. Topographic complexity, a defining feature of many mountainous landscapes, promotes ecological and geographic isolation, often accelerating speciation rates. However, the extent to which topographic complexity directly shapes diversification remains unresolved. Here, we investigate the evolutionary dynamics of An...

A primary challenge for modern phylogeography is understanding how ecology and geography, both contemporary and historical, shape the spatial distribution and evolutionary histories of species. Phylogeographic patterns are the result of many factors, including geology, climate, habitat, colonization history and lineage‐specific constraints. Assessing the relative influences of these factors is difficult because few species, re...
