Combining nuclear (nuDNA) and mitochondrial DNA (mtDNA) markers has improved the
power of molecular data to test phylogenetic and phylogeographic hypotheses and has …

A defining feature of species is that their constituting populations are connected by gene
flow. However, interspecific gene flow (introgression) can affect species integrity. If some …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

The discovery and delimitation of species has changed dramatically over time. Species
delimitation practices became more thorough and formal in the 1900s with the introduction …

Most new cryptic species are described using conventional tree‐and distance‐based
species delimitation methods (SDMs), which rely on phylogenetic arrangements and …

The radiation of Palearctic green toads (Bufotes) holds great potential to evaluate the role of
hybridization in phylogeography at multiple stages along the speciation continuum. With …

Species delimitation directly impacts on global biosecurity. It is a critical element in the
decisions made by national governments in regard to the flow of trade and to the biosecurity …

The field of molecular ecology has burgeoned into a large discipline spurred on by technical
innovations that facilitate the rapid acquisition of large amounts of genotypic data, by the …

This study addresses the causes and evolutionary consequences of introgressive
hybridization in the sympatric species of Darwin's ground finches (Geospiza) on the small …

As DNA sequences have become more readily available, it has become increasingly
desirable to infer species phylogenies from multigene data sets. Much recent work has …
