Comparing the Influence of Habitat Configuration on Population Connectivity and Genetic Structure Using Congeneric Species Across Multiple Taxa

This study compares genetic structure and population connectivity across congeneric species in river habitats, finding higher genetic diversity upstream and lower differentiation in hygropetric microhabitats.

Genetic structures of the Japanese stone loach Barbatula oreas (Cypriniformes: Nemacheilidae) in Sakhalin and Hokkaido: back dispersal from Hokkaido to Sakhalin

The paper investigates the genetic structure and phylogeographic history of Barbatula oreas in Hokkaido and Sakhalin, finding back dispersal from islands to the mainland and challenging the conventional dispersal paradigm.

Changes over a 10-year Period in the Distribution Ranges and Genetic Hybridization of Three Pelophylax Pond Frogs in Central Japan

Long-read HiFi Sequencing Correctly Assembles Repetitive heavy fibroin Silk Genes in New Moth and Caddisfly Genomes

This study uses HiFi long-read sequencing to assemble repetitive heavy fibroin genes in moth and caddisfly genomes, demonstrating its effectiveness for such challenging regions.

Development of microsatellite markers for a giant water bug, Appasus japonicus, distributed in East Asia

The paper develops 20 polymorphic microsatellite markers for the endangered giant water bug Appasus japonicus to study its genetic structure.
