- adj. (of biological species or speciation) occurring in the same or overlapping geographical areas
The first supposes that all speciation is sympatric, which is plain nonsense.
Interestingly, the 2 chameleon species are sympatric, that is, they can be found together in the same habitat.
This type of diversification-without-isolation is now called sympatric speciation, and demonstrating its existence has been one of the toughest recent nuts in evolutionary biology.
We describe the first case of an obligate predatory dung beetle and contrast its behaviour and morphology with those of its coprophagous sympatric congeners.
How do you explain the character displacement observed in sympatric populations if there is no competition?
Another endemic is the golden Cattleya orchid, (Cattleya aurea), that is sympatric in the upper Sinú with the gigas Cattleya orchid, (Cattleya warscewickzii), showing the contact zone between Magdalena Medio and Chocó-Darién; the upper Sinú is the only place where the naturally occurring hybrid, the spectacular (Cattleya X hardyana) has been found.
The sympatric occurrence of the Indian muntjac Muntiacus muntjak further complicates species identification based primarily on morphometry.
Genetic differentiation, sympatric speciation, and the origin of a diploid species of Stephanomeira.
IN allopatric, peripatric, sympatric and parapatric speciation a founder population diverges into two or more species.
In the case of sympatric speciation - a phenomenon which has actually been recorded in natural populations - it does not seem to present any barrier to speciation.
