Classical models of allopatric and parapatric divergence do not involve population restrictions; however, low genetic variability is expected when population bottlenecks are integral to divergence, as in some models of peripatric divergence and most models of
sympatric divergence.
We also aimed to draw comparisons with the
sympatric dholes by examining differences in habitat use and range in response to several physicals, biological, climatic and anthropogenic variables.
Both species are
sympatric in the Potohar range of their distribution.
Breeding systems of Bromeliaceae species: evolution of selfing in the context of
sympatric occurrence.
Exploring driving factors for habitat selection of
sympatric predators and herbivores, reactions of herbivores on habitat utilization under predation pressure, and vegetation--herbivore--predator relationships can help to deepen our understanding of herbivore and predator coexistence mechanism.
Isolation between
sympatric anadromous and resident threespine stickleback species in Mud Lake, Alaska.
Dietary breadth and overlap among five
sympatric prairie Carnivores.
Hybridization studies of the host races of Eurosta solidaginis: Implications for
sympatric speciation.
Food habits of
sympatric jaguars and pumas across a gradient of human disturbance.
In a second step, polygyny might have favored the selection of selfish reproductive strategies and then the evolution of social parasite by
sympatric speciation [1, 6, 10].
pelagic, benthic, litoral, ...) promote ecological segregation and
sympatric speciation within distribution of the range of a species as well as dietary differences (piscivory, insectivory, detritivory, ...) (Horstkotte & Strecker, 2005; Joyce et al., 2005; Barluenga, Stolting, Salzburger, Muschick, & Meyer, 2006).
