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
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.

Multiple colonizations of Lake Biwa by Sarcocheilichthys fishes and their population history
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.

Isolation and characterization of 15 microsatellite loci for the Japanese gudgeon Sarcocheilichthys variegatus
In three populations of Sarcocheilichthys from Lake Biwa and the Ashida River in western Japan, seven to 27 alleles were observed for each locus, and only one locus showed significant deviation from Hardy–Weinberg equilibrium in a population. Expand
A Novel Resource Polymorphism in Fish, Driven by Differential Bottom Environments: An Example from an Ancient Lake in Japan
The results suggest that the gudgeon populations in Lake Biwa show a state of resource polymorphism associated with differences in the bottom environment, emphasizing the importance and generality of feeding adaptation as an evolutionary mechanism that generates morphological diversification. Expand
