Rates of hybridization and introgression are increasing dramatically worldwide because of
translocations of organisms and habitat modifications by humans. Hybridization has …

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

The genetic effects of pleistocene ice ages are approached by deduction from
paleoenvironmental information, by induction from the genetic structure of populations and …

Radiations of ecologically and morphologically differentiated sympatric species can exhibit
the pattern of a burst of diversification, which might be produced by ecological divergence …

The older history of hybrid zones is explored through consideration of recent advances in
climatology, paleontology and phylogeography in the Late Cenozoic, particularly the …

Contact zones exemplify a series of stages in speciation. In unimodal hybrid zones
intermediates predominate; in bimodal zones hybrids are rare and parental forms …

Hybrid zones are 'natural laboratories' for studying the origin, maintenance and demise of
species. Theory predicts that hybrid zones can move in space and time, with significant …

This paper examines two assumptions that have formed the basis for much of the past and
present work on hybrid zones. These assumptions derive from the observation that crosses …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

KwaZulu‐Natal province in South Africa is currently the site of the world's fastest growing
HIV/AIDS epidemic, where it is estimated that between 30 and 40 percent of the adult …
