Chapter 7: Speciation and hybridization. In Molecular Markers, Natural History and Evolution (2nd edn.). Chapman and Hall, New York. Having at least briefly considered the problems of phylogenetics ...

Further, although the geographic mode of divergence has important implications for speciation via patterns of gene flow and sources of selection, speciation research has reached the point where we ...

Often this type of speciation occurs in three steps ... it is limited by this "gene flow." But gene flow is interrupted if the population becomes divided into two groups. One way this happens ...

What is unknown is whether such local ‘adaptations' are correlated with genetic differentiation, which is a necessary precursor to speciation. Future studies that incorporate ecological ...

Many factors can cause populations to diverge genetically (e.g., genetic drift, natural selection, sexual selection). Understanding the relative roles of these factors in generating contemporary ...

As is often the case in evolution, the rules of speciation are by no means ironclad ... What keeps a species coherent over time? "Gene flow" between the different populations of a species is ...

My research applies genomics and field experiments to natural hybrid zones and closely related taxa in order to investigate the architecture of reproductive isolation—the hallmark of speciation—and ...
