A new catfish, Silurus tomodai, is described based on 37 specimens; 132-514 mm > 139-514 [132-514 standard length (SL)] collected from streams of Mie, Aichi, Gifu, Shizuoka and Nagano prefectures central Honshu Island, Japan. Although S. tomodai closely related to lithophilus (Tomoda, 1961) partial mitochondrial DNA sequences, the former can be distinguished latter by position dorsal fin (predorsal-fin 28.5-32.1% vs. 30.1-33.7% SL), a shorter head (18.5-21.2% 19.5-22.2% SL) that more...
Abstract To elucidate the origins of endemic fish Lake Biwa, an ancient lake in Japan, and role diversification freshwater western we established a molecular phylogenetic framework with absolute time scale inferred historical demography large set species around lake. We used mt DNA sequences obtained from total 190 specimens, including 11 Biwa their related species, for analyses divergence estimations 2319 specimens 42 (including 14 endemics) occurring population genetic analyses....
Inle (Inlay) Lake, an ancient lake of Southeast Asia, is located at the eastern part Myanmar, surrounded by Shan Mountains. Detailed information on fish fauna in and around has long been unknown, although its outstanding endemism was reported a century ago.Based specimens collected from markets, rivers, swamps, ponds ditches Lake as well itself 2014 to 2016, we recorded total 948 occurrence data (2120 individuals), belonging 10 orders, 19 families, 39 genera 49 species. Amongst them, 13...
Abstract The area around the Sea of Okhotsk and Japan in north-western North Pacific provides opportunities for studying impact climate oscillations on evolutionary history cold-temperate species independent direct ice sheet development. We conducted a range-wide collection survey white-spotted charr, Salvelinus leucomaenis, integrated nuclear DNA mitochondrial (mtDNA) data to reveal this species. Phylogeographic analyses using genome-wide SNP revealed presence five geographically distinct...
Floodplains harbor highly biodiverse ecosystems, which have been strongly affected by both past climate change and recent human activities, resulting in a high prevalence of many endangered species these habitats. Understanding the history floodplain over wide range timescales can contribute to effective conservation planning. We reconstructed population formation Itasenpara bitterling Acheilognathus longipinnis, an fish Japan, broad timescale based on phylogenetic analysis, demographic...
Adaptive evolution of vision-related genes has been frequently observed in the process invasion new environments a wide range animal taxa. The typical example is that molecular rhodopsin associated with habitat changes aquatic animals. However, few studies have investigated during adaptive radiation across various habitats. In present study, we examined link between evolutionary patterns gene and macroscopic Gymnogobius species (Gobiidae), which adaptively radiated to diverse habitats...
Asexual vertebrates are rare and at risk of extinction due to their restricted adaptability through the loss genetic recombination. We explore mechanisms behind generation maintenance diversity in triploid asexual (gynogenetic) Carassius auratus fish, which is widespread East Asian fresh waters exhibits one most extensive distribution among despite its dependence on host sperm. Our analyses composition using dozens markers genome-wide transcriptome sequencing uncover admixed Japanese...
Loach is one of the major cypriniform fishes in freshwater habitats Japan; 35 taxa/clades have, until now, been recognised. Parallel to genetic studies, morphological examinations are needed for further development loach study, eventually ichthyology and fish biology. Digital archiving, concerning taxonomy, ecology, ethology etc., progressive challenges open science This paper aimed online publish photo images, 3D models CT scanned data all known clades loaches inhabiting Japan (103...
Abstract Countershading, characterized by a darker dorsal surface and lighter ventral surface, is common among many animals. This dorsoventral pigment polarity often thought to be adaptive coloration for camouflage. By contrast, noncountershaded (melanistic) morphs occur within species due genetic color polymorphism in terrestrial However, the with either countershaded or melanistic poorly known wild aquatic study explored nature of diverged lineage gudgeon fish (genus Sarcocheilichthys )...
We examined the genetic population structure of endangered freshwater cyprinid Acheilognathus tabira in Japanese archipelago, which has only been analyzed limited sampling previous studies, based on cytochrome b region mitochondrial gene. confirmed existence same three lineages determined study, natural distribution area Lineage I and II+III were considered to be Seto Inland Sea Ise Bay regions, respectively. Furthermore, was divided into five groups inhabiting neighboring water systems...
Hopong, a small town in the Salween (Thanlwin) River Basin, Myanmar, is located 35 km northeast of Inle Lake, famous ancient lake with numerous endemic fish species. We surveyed fauna spring pond Hopong 2016, 2019 and 2020 identified 25 Of these, seven, including Inlecyprisauropurpureus Sawbwaresplendens, had been considered to Lake at least three species were genetically unique. Eight suspected or definite introduced species, Oreochromisniloticus Gambusiaaffinis. unable identify nemacheilid...
Abstract Vicia sepium is a perennial herb widely distributed throughout the Eurasian continent. However, its distribution in Japan limited to Mt. Ibuki and small parts of central southern Hokkaido. Therefore, each Japanese V. lineage has been considered have introduced separately from Europe. Here, we examined whether species was or not on basis cpDNA sequences genome-wide SNPs overseas samples. Both haplotype network nuclear DNA phylogenetic tree showed that monophyletic. Furthermore,...
Abstract Inle Lake is an ancient lake in Myanmar, which important area with unique and diverse fauna. Its ichthyofauna believed to have formed non‐radiatively, but the historical processes are poorly understood. To elucidate mechanisms that shape species diversity this moderately isolated biogeographical ‘island’, study focused on a typical endemic fish of Lake, Channa harcourtbutleri (Channidae, Anabantiformes), its widely distributed sister species, C. limbata , estimated distribution...
Abstract Vicia sepium (bush vetch) is a perennial legume widely distributed throughout the Eurasian continent. However, its distribution in Japan limited to Mt. Ibuki and small parts of central southern Hokkaido. Therefore, each Japanese V. lineage has been considered have introduced separately from Europe. Here, we examined whether species was or not on basis cpDNA sequences genome-wide SNPs overseas samples. Both haplotype network nuclear DNA phylogenetic tree showed that monophyletic....
