Conversely, zoologist Michael J. D. White considered two populations sympatric if genetic interbreeding was viable within the habitat overlap. This may be further specified as sympatry occurring within one deme; that is, reproductive individuals must be able to locate one another in the same population in order to be sympatric.
[24] [25] Hybridization here is defined as when different but adjacent varieties of the same species (or generally of the same taxonomic rank) interbreed, which helps overcome local selection. [1] However other studies reveal that ecotypes may emerge even at very small scales (of the order of 10 m), within populations, and despite hybridization ...
Genetic admixture occurs when previously isolated populations interbreed resulting in a population that is descended from multiple sources. It can occur between species, such as with hybrids, or within species, such as when geographically distant individuals migrate to new regions. It results in gene pool that is a mix of the source populations.
In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two "end populations" in the series, which are too distantly related to interbreed, though there is a potential gene flow between each "linked" population and the next ...
By preventing populations from successfully interbreeding, these incompatibilities can reinforce reproductive isolation and thereby increase the chance of speciation. behavioral isolation biogeography The scientific study of the spatial distributions of biological organisms, populations, and species.
The term "population" is defined as a group of interbreeding individuals in similar geographic area that undergo negligible gene flow with other groups of the species. [2] Typically, MVP is used to refer to a wild population, but can also be used for ex situ conservation (Zoo populations).
In biological classification, subspecies (pl.: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (), but that can successfully interbreed.
This occurs in cases where two subspecies are connected via one or more intermediate populations, each of which is in turn intermediate to its adjacent populations and exhibits more or less the same amount of variability as any other population within the species. Adjacent populations and subspecies are subject to cline intergradation, and in ...
