Rising water temperatures in rivers due to climate change are already having observable
impacts on river ecosystems. Warming water has both direct and indirect impacts on aquatic …

When gene flow has been restricted between populations, the genetic structure of such
species often reflects geohistory and climate changes. Populations of species inhabiting …

Organisms that inhabit the alpine zone tend to have distribution areas that are isolated and
scattered in patches, in effect 'sky islands'. We focused on Pseudostenophylax caddisflies, a …

The distribution of organisms is influenced by complex factors such as the phylogenetic
evolutionary histories of species, the physiological and ecological characteristics of …

In the present study, we add genetic data of the mayfly Cloeon dipterum collected from the
Japanese Islands to the established molecular phylogenetic knowledge in the mitochondrial …

Abstract Changes in river environments due to elevation gradients have a great impact on
living organisms. In particular, with respect to aquatic insects, it has been recognized that …

DNA barcoding has been actively used as a method for species identification, and it will
become an increasingly important method in the future. However, DNA barcoding can …

We focused on Meloe beetles that have lost all flight ability, and conducted molecular
phylogeographic analyses based on their mitochondrial DNA COI and nuclear DNA EF1-α …

In this study we present evidence of an ongoing speciation event in the Japanese
Archipelago. The Kisaura nozakii species complex (Philopotamidae) is a group of a small …

A description of the second species of the genus Bleptus Eaton, 1885 (Ephemeroptera:
Heptageniidae) from Japan, and phylogenetic relationships of two Bleptus mayflies inferred …
