The emerging field of speciation genomics is advancing our understanding of the evolution
of reproductive isolation from the individual gene to a whole-genome perspective. In this …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

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 …

A fully updated guide to the increasingly prevalent use of molecular data in ecological
studies Molecular ecology is concerned with how molecular biology and population genetics …

Abstract Since Darwin published the “Origin,” great progress has been made in our
understanding of speciation mechanisms. The early investigations by Mayr and Dobzhansky …

The classification of reproductive isolating barriers laid out by Dobzhansky and Mayr has
motivated and structured decades of research on speciation. We argue, however, that this …

Studies of natural hybridization have generally addressed evolutionary ques-tions using one
of the three following frameworks:(i) taxonomy or systematics (57, 59, 73, 79, 111, 172);(ii) …

▪ Abstract Over the years, the evolutionary importance of natural hybridization has been a
contentious issue. At one extreme is the relatively common view of hybridization as an …

Hybrid zones provide a powerful opportunity to analyze ecological and evolutionary
interactions between divergent lineages. As such, research on hybrid zones has played a …

Hybrid zones have been promoted as windows on the evolutionary process and as
laboratories for studying divergence and speciation. Patterns of divergence between …
