Sympatric speciation suggested by monophyly of crater lake cichlids
THE existence of sympatric speciation—that populations diverge into species in the absence of physical or ecological barriers—is controversial1–6. The East African Great Lakes harbour hundreds ofExpand

Phylogeography of the bullhead Cottus gobio (Pisces: Teleostei: Cottidae) suggests a pre‐Pleistocene origin of the major central European populations
The bullhead Cottus gobio is a small, bottom‐dwelling fish consisting of populations that have not been subject to transplantations or artificial stocking. It is therefore an ideal model species forExpand

Genetic and ecological divergence of a monophyletic cichlid species pair under fully sympatric conditions in Lake Ejagham, Cameroon
Although there is mounting evidence that speciation can occur under sympatric conditions, unambiguous examples from nature are rare and it is almost always possible to propose alternative allopatricExpand

Reticulate sympatric speciation in Cameroonian crater lake cichlids
BackgroundTraditionally the rapid origin of megadiverse species flocks of extremely closely related species is explained by the combinatory action of three factors: Disruptive natural selection,Expand

The root of the East African cichlid radiations
BackgroundFor decades cichlid fishes (Perciformes: Cichlidae) of the East African cichlid radiations (Teleostei: Cichlidae) have served as natural experimental subjects for the study of speciationExpand

Bigger Is Better: Characteristics of Round Gobies Forming an Invasion Front in the Danube River
Few studies have systematically investigated differences in performance, morphology and parasitic load of invaders at different stages of an invasion. This study analyzed phenotype-environmentExpand

Comparative feeding ecology of invasive Ponto-Caspian gobies
Invasions of Ponto-Caspian gobiid fishes are suspected to cause regime shifts in freshwater ecosystems. This study compared the trophic niche differentiations of Neogobius melanostomus and PonticolaExpand

Molecular phylogenetics of Gobioidei and phylogenetic placement of European gobies.
Gobioidei is one of the largest suborders of teleost fishes, with nearly 2000 extant species currently recognized. They have a worldwide distribution and show a spectacular variety in morphology,Expand

Age and spread of the haplochromine cichlid fishes in Africa.
The Haplochromini are by far the most species-rich cichlid fish tribe that originated along with the so-called primary radiation of the Lake Tanganyika cichlid species flock, i.e. at the same timeExpand

Adaptive radiation and hybridization in Wallace's Dreamponds: evidence from sailfin silversides in the Malili Lakes of Sulawesi
Adaptive radiations are extremely useful to understand factors driving speciation. A challenge in speciation research is to distinguish forces creating novelties and those relevant to divergence andExpand
