Many studies propose that Quaternary climatic cycles contracted and/or expanded the
ranges of species and biomes. Strong expansion–contraction dynamics of biomes presume …

Species delimitation is a first step for realizing the extent of biodiversity and is relevant for all
downstream applications in biology. The production of large genome-scale datasets for non …

Abstract Aim The Australian deserts are home to a remarkable diversity of taxa that might
appear to have evolved in the absence of topographic and physical barriers to dispersal. In …

Many phylogeographic studies on species with large ranges have found genetic–
geographic structure associated with changes in habitat and physical barriers preventing or …

Whether species demography and diversification are driven primarily by extrinsic
environmental changes such as climatic oscillations in the Quaternary or by intrinsic …

A central paradigm in conservation biology is that population bottlenecks reduce genetic
diversity and population viability. In an era of biodiversity loss and climate change …

Pleistocene climatic fluctuations (PCF) are frequently highlighted as important evolutionary
engines that triggered cycles of biome expansion and contraction. Although there is ample …

High tropical species diversity is often attributed to evolutionary dynamics over long
timescales. It is possible, however, that latitudinal variation in diversification begins when …

Parallel evolution can be expected among closely related taxa exposed to similar selective
pressures. However, parallelism is typically stronger at the phenotypic level, while genetic …

Inferring the history of divergence between species in a framework that permits the presence
of gene flow has been crucial for characterizing the “gray zone” of speciation, which is the …
