Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

20 questions on Adaptive Dynamics [PDF]

, 2005
Adaptive Dynamics is an approach to studying evolutionary change when fitness is density or frequency dependent. Modern papers identifying themselves as using this approach first appeared in the 1990s, and have greatly increased up to the present ...

Multispecies Outcomes of Sympatric Speciation after Admixture with the Source Population in Two Radiations of Nicaraguan Crater Lake Cichlids.

PLoS Genetics, 2016
The formation of species in the absence of geographic barriers (i.e. sympatric speciation) remains one of the most controversial topics in evolutionary biology.

Ecosystem size predicts eco-morphological variability in a postglacial diversification [PDF]

, 2017
Identifying the processes by which new phenotypes and species emerge has been a long-standing effort in evolutionary biology. Young adaptive radiations provide a model to study patterns of morphological and ecological diversification in environmental ...

Genome-wide tests for introgression between cactophilic Drosophila implicate a role of inversions during speciation [PDF]

, 2015
K.L. was funded by a junior research fellowship from the National Environmental Research Council, UK (NE/I020288/1, NBAF659).Models of speciation-with-gene-flow have shown that the reduction in recombination between alternative chromosome arrangements ...

Sympatric Speciation: Why the Controversy? [PDF]

Current Biology, 2006
Two recent studies provide convincing evidence that speciation without geographic isolation--sympatric speciation--has occurred within isolated island habitats, but we remain ignorant of how frequent the process really is.

Experimental swap of Anopheles gambiae's assortative mating preferences demonstrates key role of X-chromosome divergence island in incipient sympatric speciation.

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 ...

Differential genetic responses to the stress revealed the mutation-order adaptive divergence between two sympatric ginger species

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.

The genetic architecture underlying the evolution of a rare piscivorous life history form in brown trout after secondary contact and strong introgression [PDF]

, 2018
Identifying the genetic basis underlying phenotypic divergence and reproductive isolation is a longstanding problem in evolutionary biology. Genetic signals of adaptation and reproductive isolation are often confounded by a wide range of factors, such as

Sympatric speciation through intraspecific social parasitism [PDF]

Proceedings of the National Academy of Sciences, 2003
Sympatric speciation through intraspecific social parasitism has been proposed for the evolution of Hymenopteran workerless parasites. Such inquilines exploit related host taxa to produce their own sexual offspring. The relatedness of inquilines to their hosts has been generalized in Emery's rule, suggesting that social parasites are close or the ...
