Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

The interactions between organisms and their environments can shape distributions of
spatial genetic variation, resulting in patterns of isolation by environment (IBE) in which …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

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 …

Local adaptation has been a major focus of evolutionary ecologists working across diverse
systems for decades. However, little of this research has explored variation at …

Individuals often differ in what they do. This has been recognised since antiquity.
Nevertheless, the ecological and evolutionary significance of such variation is attracting …

Dispersal is a process of central importance for the ecological and evolutionary dynamics of
populations and communities, because of its diverse consequences for gene flow and …

Habitat fragmentation, an important element of current global change, has profound
repercussions on population and species extinction. Landscape fragmentation reduces …

Ecological speciation is the process by which reproductively isolated populations emerge as
a consequence of divergent natural or ecologically-mediated sexual selection. Most …
