Sympatric speciation, the formation of species in the absence of geographical barriers, remains one of the most contentious concepts in evolutionary biology. [] Key Method Our study includes phylogeographic, population-genetic (based on mitochondrial DNA, microsatellites and amplified fragment length polymorphisms), morphometric and ecological analyses. We find, first, that crater Lake Apoyo was seeded only once by the ancestral high-bodied benthic species Amphilophus citrinellus, the most common cichlid…
Rapid sympatric ecological differentiation of crater lake cichlid fishes within historic times
TLDR
This study provides empirical evidence of eco-morphological differentiation occurring very quickly after the colonization of a new and vacant habitat, and suggests that this population of Midas cichlid fishes may be in a very early stage of speciation (incipient species), promoted by disruptive selection and ecological diversification.

Sympatric speciation by allochrony in a seabird
TLDR
Oceanodroma castro (the Madeiran or band-rumped storm-petrel) is a small seabird that nests on tropical and subtropical islands throughout the Atlantic and Pacific Oceans, and the first evidence for sympatric speciation by allochrony in a tetrapod is found.
Sympatric and Allopatric Diversification in the Adaptive Radiations of Midas Cichlids in Nicaraguan Lakes
TLDR
The Nicaraguan Midas cichlid species complex is a natural experiment where fish from a large source population from turbid and shallow great lakes very recently (<20,000 years ago) colonized eight small crater lakes, and parallel speciation happened in the two small crater lake radiations, where ecomorphologically similar species evolved repeatedly.
Crater Lake Apoyo Revisited - Population Genetics of an Emerging Species Flock
TLDR
A first comprehensive data set of population genetic (mtDNA & AFLPs) proxies of species level differentiation for a representative set of individuals of all six endemic Amphilophus species occurring in Crater Lake Apoyo is presented.
Are sympatrically speciating Midas cichlid fish special? Patterns of morphological and genetic variation in the closely related species Archocentrus centrarchus
TLDR
A combined analysis of the mitochondrial control region in A. centrarchus and Midas cichlids suggests that a difference between lineages in the timing of crater lake colonization cannot be invoked as an explanation for the difference in their levels of diversification.
Phylogeography, colonization and population history of the Midas cichlid species complex (Amphilophus spp.) in the Nicaraguan crater lakes
TLDR
A comprehensive and integrative phylogeographic analysis of the complete Midas Cichlid species complex in Nicaragua covering the entire distributional range is presented, and levels of phenotypic differentiation, and speciation events, appeared independent of both factors.
Multispecies Outcomes of Sympatric Speciation after Admixture with the Source Population in Two Radiations of Nicaraguan Crater Lake Cichlids
TLDR
The evolutionary history of two small-scale radiations of Midas cichlids inhabiting crater lakes Apoyo and Xiloá is reconstructed through a comprehensive genomic data set to support a scenario of speciation that was initiated in sympatry and does not result from secondary contact of already partly diverged populations.
Sympatric speciation in a genus of marine reef fishes
TLDR
The study addresses limitations of previous studies and supports new criteria for inferring sympatric speciation, as well as comparing aspects of reproductive isolation between allopatric and sympatrics taxa both in nature and in the laboratory.
Phylogenomics of pike cichlids (Cichlidae: Crenicichla): the rapid ecological speciation of an incipient species flock
TLDR
The results suggest that the Uruguay River species flock; URSF consists of incipient species that arose via ecological speciation associated with the exploration of novel trophic roles, and most species as well as delimited genetic groups are recovered.

The Midas cichlid species complex: incipient sympatric speciation in Nicaraguan cichlid fishes?
TLDR
Allopatric genetic differentiation of populations of A. citrinellus from different lakes and distant locations within Lake Managua is uncovered and several sympatric populations based on colouration but not on the morphology of the pharyngeal jaws are uncovered.
Genetic and ecological divergence of a monophyletic cichlid species pair under fully sympatric conditions in Lake Ejagham, Cameroon
TLDR
These findings are congruent with recent theoretical models for sympatric speciation, which show that differential ecological adaptations in combination with assortative mating could easily lead to speciation in sympatry.
Assortative mating among rock‐dwelling cichlid fishes supports high estimates of species richness from Lake Malawi
TLDR
All taxa showed high levels of allelic diversity providing evidence that genetic bottlenecking may have been of limited importance in the speciation process, and assortative mating among taxa differing only in male colouration is supportive of theories that speciation in these fishes has been driven by sexual selection by female choice.
Can sympatric speciation by disruptive sexual selection explain rapid evolution of cichlid diversity in Lake Victoria
TLDR
Data from 41 species endemic to Lake Victoria support the hypothesis that disruptive sexual selection on colour polymorphisms has caused sympatric speciation and help to explain the rapid radiation of haplochromine species flocks.
Body shape variation in cichlid fishes of the Amphilophus citrinellus species complex.
TLDR
Within A. citrinellus, there is considerable variation among lakes as well as between the alternative colour and trophic morphs, suggesting local differentiation based on genetic and ecophenotypic mechanisms.
On the origin of species by sympatric speciation
TLDR
This work uses multilocus genetics to describe sexual reproduction in an individual-based model and considers the evolution of assortative mating, which leads to reproductive isolation between ecologically diverging subpopulations and conforms well with mounting empirical evidence for the sympatric origin of many species.
Rapid and coupled phenotypic and genetic divergence in Icelandic Arctic char (Salvelinus alpinus)
TLDR
Data is presented on Arctic char (Salvelinus alpinus) in Icelandic lakes exhibiting a variable degree of phenotypic and genotypic segregation, suggesting a role for trophic adaptation as a driving force in morph segregation.
Interactions among quantitative traits in the course of sympatric speciation
TLDR
The hypergeometric phenotypic model is used to show that sympatric speciation is possible even when fitness and mate choice depend on different quantitative traits, so that speciation must involve formation of covariance between these traits.
Nonsynchronous Spatial Overlap of Lizards in Patchy Habitats
TLDR
The first observation may be related to the first in the following way: nonsynchronous spatial overlap could dictate relatively great resource overlap for species coinhabiting patchy or edge areas, requiring great differences between the species in prey size in addition to those in climatic habitat.
A Quantitative Study of Long-Term Courtship: I. Ethological Isolation Between Sympatric Populations of the Midas Cichlid, Cichlasoma Citrinellum, and the Arrow Cichlid, C. Zaliosum
TLDR
Ethological isolating mechanisms are sufficient to explain the maintenance of species isolation between C. citrinellurn and C. zaliosum in a sympatric situation in Lake Apoyo.
