Ecological opportunity–through entry into a new environment, the origin of a key innovation
or extinction of antagonists–is widely thought to link ecological population dynamics to …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

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 …

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 …

Fragmentation of animal and plant populations typically leads to genetic erosion and
increased probability of extirpation. Although these effects can usually be reversed by re …

Ecological differences often evolve early in speciation as divergent natural selection drives
adaptation to distinct ecological niches, leading ultimately to reproductive isolation. Although …

Divergent natural selection has been shown to promote speciation in a wide range of taxa.
For example, adaptation to different ecological environments, via divergent selection, can …

Recent interest in the role of ecology in species formation has led to renewed discussion of
the stages in the process of speciation. Although attempts to classify the stages in the …

Fungi are ideal model organisms for dissecting the genomic bases of adaptive divergence in
eukaryotes. They have simple morphologies and small genomes, occupy contrasting, well …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …
