We outline several processes that can drive speciation. Natural selection and speciation: ‘Ecological speciation'. Biologists have long been fascinated with — and sought to explain — the ...

They say that hindsight is 20/20, and though the theory of ecological speciation—which holds that new species emerge in response to ecological changes—seems to hold in retrospect, it has been ...

The conditions for ecological speciation are more restrictive than for allopatric speciation (Figure 2). Because adaptive (parapatric or sympatric) speciation is so much less common than non ...

Chapter 7: Speciation and hybridization ... These mechanisms may be genetic, including repeated founder events, hybridization, and sexual selection, or ecological, including shifts in habitat and/or ...

Paine is interested in the dispersal and speciation patterns of the australopithecines, focusing on the broad ecological and biogeographical context in which they occurred. His advisor was Matt ...

Sunflower genetic, genomic and ecological resources. Molecular Ecology ... Number and size of genomic islands of differentiation do not vary with geography of speciation. Nature Communications 4:1827.

The ecological niches exert the selection pressures ... The ancestral finch was a ground-dwelling, seed-eating finch. After the burst of speciation in the Galapagos, a total of 14 species would ...

I am interested in evolutionary processes in plants. Current research projects focus on the genetic basis of adaptation, the evolution of reproductive isolation and ecological speciation, as well as ...
