Ecological speciation is a form of speciation arising from reproductive isolation that occurs due to an ecological factor that reduces or eliminates gene flow between two populations of a species.
Ecological speciation is the process by which new species form as a consequence of divergent natural selection between contrasting ecological environments. Numerous examples of this process now exist.
20 sty 2005 · Here we review ecological speciation by considering its constituent components: an ecological source of divergent selection, a form of reproductive isolation, and a genetic mechanism linking the two.
This chapter defines ecological speciation as the process by which barriers to gene flow evolve between populations as a result of ecologically based divergent selection between environments. It provides a brief history of the ecological speciation hypothesis, dating back to Charles Darwin's On the Origin of Species in 1895.
More specifically, ecological speciation is defined as the process by which barriers to gene flow evolve between populations as a result of ecologically-based divergent selection between...
20 lis 2018 · There are many ways by which natural (incl. sexual) selection can cause ecological speciation. Adapting to specific aspects of one environment (e.g., food resources) may change traits (morphology, physiology, behavior, and life history) of a local population.
Speciation, the formation of new and distinct species by splitting a single lineage into two or more genetically independent ones. Hypotheses regarding how speciation begins differ in the role of geographic isolation and the origin of reproductive isolation (preventing populations from breeding with one another).
