Frontiers in Plant Science, 2023 Habitat heterogeneity leads to genome-wide differentiation and morphological and ecological differentiation, which will progress along the speciation continuum, eventually leading to speciation.

Evolution: Sympatric Speciation the Eusocial Way [PDF]
Current Biology, 2014 Sympatric speciation normally requires particular conditions of ecological niche differentiation. However, ant social parasites have been suspected to arise sympatrically, because (dis)loyalty to eusocial kin-structures induces disruptive selection for dispersal and inbreeding. A new study documents this process in unprecedented detail.

Within-host speciation of malaria parasites.
PLoS ONE, 2007 BackgroundSympatric speciation-the divergence of populations into new species in absence of geographic barriers to hybridization-is the most debated mode of diversification of life forms. Parasitic organisms are prominent models for sympatric speciation,

Early stages of sympatric homoploid hybrid speciation in crater lake cichlid fishes
Nature Communications, 2022 Here, the authors present a rare example of sympatric homoploid hybrid speciation, without ploidy changes, in the Midas cichlid fishes from Nicaragua. Midas cichlid hybrids occupy a different ecological niche, likely facilitated by body shape adaptations.

Frontiers in Microbiology, 2022 The sympatric occurrence of closely related lineages displaying conserved morphological and ecological traits is often characteristic of free-living microbes. Gene flow, recombination, selection, and mutations govern the genetic variability between these

The European Zoological Journal, 2023 Sympatric distribution and syntopy are not common in closely related species since sporadic crosses may lead to the formation of hybrid zones disrupting the differentiation of sympatric incipient species.

PLoS Genetics, 2015 Although many theoretical models of sympatric speciation propose that genes responsible for assortative mating amongst incipient species should be associated with genomic regions protected from recombination, there are few data to support this theory ...

BMC Genomics, 2018 Background Divergent genetic responses to the same environmental pressures may lead sympatric ecological speciation possible. Such speciation process possibly explains rapid sympatric speciation of island species.

Sympatric Speciation in the Genomic Era [PDF]
Trends in Ecology & Evolution, 2018 Sympatric speciation has been of key interest to biologists investigating how natural and sexual selection drive speciation without the confounding variable of geographic isolation. The advent of the genomic era has provided a more nuanced and quantitative understanding of the different and often complex modes of speciation by which sympatric sister ...

Sympatric Speciation by Sexual Selection: A Critical Reevaluation [PDF]
The American Naturalist, 2004 Several empirical studies put forward sexual selection as an important driving force of sympatric speciation. This idea agrees with recent models suggesting that speciation may proceed by means of divergent Fisherian runaway processes within a single population.
