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

Mitochondrial DNA (mtDNA) has been used to study molecular ecology and
phylogeography for 25 years. Much important information has been gained in this way, but it …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

▪ Abstract Many uses of gene trees implicitly assume that nominal species are monophyletic
in their alleles at the study locus. However, in well-sampled gene trees, certain alleles in one …

Whether interspecific hybridization is important as a mechanism that generates biological
diversity is a matter of controversy. Whereas some authors focus on the potential of …

Hybridization has long been considered a process that prevents divergence between
species. In contrast to this historical view, an increasing number of empirical studies claim to …

Mitochondrial DNA (mtDNA) has been a marker of choice for reconstructing historical
patterns of population demography, admixture, biogeography and speciation. However, it …

▪ Abstract Species are routinely used as fundamental units of analysis in biogeography,
ecology, macroevolution, and conservation biology. A large literature focuses on defining …

The literature about species concepts might be larger than that about any other subject in
evolutionary biology, but the issue of empirically testing species boundaries has been given …

A goal of evolutionary biology is to understand the roles of geography and ecology in
speciation. The recent shared ancestry of sister species can leave a major imprint on their …
