Nematomorph parasites indirectly alter the food web and ecosystem function of streams through behavioural manipulation of their cricket hosts.
This is the first experimental demonstration that host manipulation by a parasite can reorganise a community and alter ecosystem function. Expand
Evolution of feeding specialization in Tanganyikan scale-eating cichlids: a molecular phylogenetic approach
Interspecific phylogenetic analyses for all nine known species in the tribe Perissodini using amplified fragment length polymorphism (AFLP) analyses of the nuclear DNA demonstrated for the first time the evolutionary process leading from generalised to highly specialized scale eating, with diversification in feeding morphology and behaviour among species. Expand
Nematomorph parasites drive energy flow through a riparian ecosystem.
In a Japanese headwater stream, camel crickets and grasshoppers were 20 times more likely to enter a stream if infected by a nematomorphic parasite (Gordionus spp.), corroborating evidence that nematomorphs manipulate their hosts to seek water where the parasites emerge as free-living adults.

Phylogeography of White-Spotted Charr (Salvelinus leucomaenis) Inferred from Mitochondrial DNA Sequences
The data demonstrate that the current subspecies designation does not reflect the phylogeography of this species based on mtDNA analysis, and showed that genetic variation was far more pronounced within subspecies than among subspecies (i.e., among discrete regions). Expand
A RAD-based linkage map and comparative genomics in the gudgeons (genus Gnathopogon, Cyprinidae)
The dense SNP-based linkage map presented here provides a basis for future QTL analysis of the genetic architecture underlying adaptive phenotypic evolution of Gnathopogon and will also be useful for transferring genomic information from a “traditional” model fish species, zebrafish, to screen candidate genes underlying ecologically important traits of the gudgeons.

Comparison of genetic population structure between two cyprinids, Hemigrammocypris rasborella and Pseudorasbora pumila subsp., in the Ise Bay basin, central Honshu, Japan
Their genetic population structures were revealed, using sequence data from the mitochondrial cytochrome b gene, and then compared, suggesting that effective population size of P. pumila subsp. Expand
Fossil bagrid catfishes from Japan and their zoogeography, with description of a new species,Pseudobagrus ikiensis
Morphological characteristics of fossil bagrid catfishes from six Miocene to Pleistocene localities in Japan are described and a new species of the Middle Miocene bagrid, Pseudobagrus ikiensis, is described, which is morphologically close to the extant P. nudiceps. Expand
Control of micropore formation in the carbonized ion exchange resin by utilizing pillar effect
Abstract A new method is presented for controlling the micropore structure of porous carbon by use of pillar effect of metal and/or sulfur compounds. An ion exchange resin having sulfonic acid groupsExpand
