Divergent natural selection rooted in differential resource use can generate and maintain intraspecific eco-morphological divergence (i.e., resource polymorphism), ultimately leading to population splitting and speciation. Differing bottom environments create lake habitats with different benthos communities, which may cause selection in benthivorous fishes. Here, we document the nature of eco-morphological and genetic divergence among local populations of the Japanese gudgeon Sarcocheilichthys… Expand
Stable resource polymorphism along the benthic littoral–pelagic axis in an invasive crayfish
TLDR
These findings demonstrated that invasive P. clarkii can display strong within‐population phenotypic variability in recent populations, and this could lead to contrasting ecological impacts between littoral and pelagic individuals. Expand
Multiple colonizations of Lake Biwa by Sarcocheilichthys fishes and their population history
TLDR
Coalescent-based population analyses indicated that the local populations colonized the rocky bottom habitat in Lake Biwa from other habitats after the Last Glacial Maximum, likely reflecting past environmental changes in the lake, including the disappearance of rocky areas during the glacial climate.

When Anthropogenic River Disturbance Decreases Hybridisation between Non-Native and Endemic Cyprinids and Drives an Ecomorphological Displacement towards Juvenile State in Both Species
TLDR
This study reveals a diversity of relationships between two genetically compatible species and emphasizes constraints on the invasion process in disturbed areas and suggested that habitat degradation induced similar ecomorphological trait changes in the two species and their hybrids. Expand
The origins of limnetic forms and cryptic divergence in Gnathopogon fishes (Cyprinidae) in Japan
TLDR
The origin of the limnetic forms and the population divergence of the Japanese Gnathopogon species, using molecular phylogenetic and phylogeographic analyses, revealed three major lineages in G. elongatus, which was inferred to originate in the present Lake Biwa in the late Pleistocene. Expand
Phylogeny and historical demography of endemic fishes in Lake Biwa: the ancient lake as a promoter of evolution and diversification of freshwater fishes in western Japan
TLDR
The phylogenetic and historical demographic evidence suggests that there was a time lag between phylogenetic divergence and population establishment and that phenotypic adaptation of some endemic species to the limnetic environment occurred much later than the divergences of those endemic lineages.

Origin and Diversification of Freshwater Fishes in Lake Biwa
Lake Biwa is the largest and oldest lake in Japan. It harbors more than a thousand animal and plant species, including 67 indigenous freshwater fish species/subspecies with 16 endemic or semi-endemicExpand
Trophic-based diversification in benthivorous charrs (Salvelinus) dwelling littoral zones of Northern lakes
Charrs of the genus Salvelinus form distinct trophic morphs living in sympatry in numerous postglacial lakes. Here we demonstrate that charrs can diversify into amphipod foraging specialists andExpand
The role of geography and ecology in shaping repeated patterns of morphological and genetic differentiation between European minnows (Phoxinus phoxinus) from the Pyrenees and the Alps
TLDR
Substantial population heterogeneity was found at the genetic level, suggesting that selection and population specific genetic drift act in concert to affect genetic divergence. Expand
Parallel and non-parallel morphological divergence among foraging specialists in European whitefish (Coregonus lavaretus)
TLDR
The results indicate that divergent natural selection resulting from foraging specialization is driving and/or maintaining the observed parallel morphological divergence between whitefish specializing in feeding on profundal and littoral resources in three separate lakes. Expand
Indirect trophic interactions with an invasive species affect phenotypic divergence in a top consumer
TLDR
A greater phenotypic divergence between littoral and pelagic individuals in lakes with zebra mussels is found and a mussel-mediated increase in pelagic and benthic resource availability is proposed as a major factor underlying this divergence. Expand

Resource polymorphism in a Patagonian fish Percichthys trucha (Percichthyidae): phenotypic evidence for interlake pattern variation
TLDR
While there are some strong parallels among lakes in the development of a trophic polymorphism, differences in environmental conditions have led to substantial differences between lakes, resulting in ­different ecological roles of common morphotypes within different lakes. Expand

TLDR
Evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia is presented and the possibility that competition for food has played a critical role in the divergence between species is considered. Expand

TLDR
It is shown that adaptation to divergent predator regimes is driving ecological speciation as a by-product of divergence in ecologically important traits, producing interspecific patterns that persist long after speciation events have completed. Expand

The results of complementary studies of genetics and reproductive biology initiated to resolve the biological status of cichlids of Cuatro Cienegas suggest that both forms belong to a single polymorphic species. Expand

Findings show that variation in morphology between habitats differs during ontogeny in a way that corresponds to functional expectations for fish species that occupy these habitats. Expand

The results in this thesis show that individual variation in diet and habitat choice is a common phenomenon with lots of ecological and evolutionary implications and there are many mechanisms involved. Expand

Character Release and Displacement in Fishes: A Neglected Literature
TLDR
It is shown that competition is frequently a diversifying force that creates differences between species and differences within species when other closely related species are absent, and the lake environment can be viewed as a set of non-Hutchinsonian or "environmental" niches that exist apart from the species that occupy them.

The genetic mosaic suggests a new role for hitchhiking in ecological speciation
TLDR
It is shown that FST outliers between a pair of incipient species are significantly clustered around QTL for traits that cause ecologically based reproductive isolation, and extensive ‘divergence hitchhiking’ occurs. Expand
