Wolbachia and nuclear–nuclear interactions contribute to reproductive incompatibility in the spider mite Panonychus mori (Acari: Tetranychidae)
Maternally transmitted bacteria of the genus Wolbachia are obligate, intracellular symbionts that are responsible for cytoplasmic incompatibility in a wide range of arthropods such as insects and… Expand
Complete mitochondrial genomes of two Japanese precious corals, Paracorallium japonicum and Corallium konojoi (Cnidaria, Octocorallia, Coralliidae): notable differences in gene arrangement.
Precious coral are taxonomically a group of corals that belong to the family Coralliidae within the order Alcyonacea, subclass Octocorallia, and class Anthozoa, whose skeletal axes are used for… Expand

SynopsisFish assemblages at an artificial reef site, a natural reef site and a sandy-mud bottom site, on the shelf (depth 130 m) off Iwate Prefecture, northern Japan, were surveyed by using a bottom… Expand
Isolation of polymorphic microsatellite markers from Hymeniacidon sinapium (Porifera: Demospongiae: Halichondrida)
Eight dinucleotide microsatellite markers were developed on Hymeniacidon sinapium (Porifera: Demospongiae), common littoral sponge around Japan, to investigate population genetic structure. Two to 10… Expand
Description of a New Species of Astrophiura (Echinodermata : Ophiuroidea) from Tosa Bay, Japan, and Several of Its Remarkable Anatomical Characteristics

The existing taxonomy of Euryalida, one of the two orders of the Ophiuroidea (Echinodermata), is uncertain and characterized by controversial delimitation of taxonomic ranks from genus to… Expand
Molecular phylogeny based on increased number of species and genes revealed more robust family-level systematics of the order Euryalida (Echinodermata: Ophiuroidea).
Previous molecular analysis of the order Euryalida (Echinodermata: Ophiuroidea), has identified three monophyletic families, the Euryalidae, Asteronychidae and Gorgonocephalidae. However,… Expand
Contrasting genetic structure of two Pacific Hymeniacidon species
The geographic genetic structure of two common encrusting sponges, Hymeniacidon sinapium and Hymeniacidon flavia (family Halichondriidae), was investigated using two DNA markers, Internal Transcribed… Expand
A new genus Squamophis of Asteroschematidae (Echinodermata, Ophiuroidea, Euryalida) from Australia
Abstract Squamophis, a new genus of brittle star is described. Two species are included in the genus: Squamophis amamiensis (Okanishi & Fujita, 2009) from south-western Japan and Squamophis… Expand
Photographic observations of the life style of a deep-sea ophiuroid Asteronyx loveni (Echinodermata)
Abstract The life style of a deep-sea ophiuroid, Asteronyx loveni was studied from underwater photographs (7 stations) and trawled samples (11 stations) between about 800 and 1700 m along the Pacific… Expand
