Variability of diet-tissue isotopic fractionation in estuarine macrobenthos
Juveniles of bivalves Mactra veneriformis and Ruditapes philippinarum, and ghost shrimps Nihonotrypaea japonica and N. harmandi were reared on a microalga of a constant isotopic value to quantifyExpand

Isotopic evidence for phytoplankton as a major food source for macrobenthos on an intertidal sandflat in Ariake Sound, Japan
To delineate a soft-shore trophic structure, macrobenthos was collected from an intertidal sandflat at the mouth of the Shirakawa River in the central part of Ariake Sound, Kyushu, Japan, on 3Expand

Life history of the ghost shrimp, Callianassa Japonica Ortmann (Decapoda : Thalassinidea), on an intertidal sandflat in western Kyushu, Japan
Growth, density, survival, and reproduction were examined for the population of the ghost shrimp, Callianassa japonica Ortmann, inhabiting an intertidal sandflat in western Kyushu, Japan, based onExpand

Food sources for three species of Nihonotrypaea (Decapoda: Thalassinidea: Callianassidae) from western Kyushu, Japan, as determined by carbon and nitrogen stable isotope analysis
Three species of the callianassid genus Nihonotrypaea occur intertidally in the Ariake Sound estuarine system, southern Japan; they consist of two sandflat species (N. japonica; N. harmandi) and oneExpand

Inhibition of larval recruitment of ARmandia sp. (Polychaeta: Opheliidae) by established adults of Pseudopolydora paucibranchiata (Okuda) (Polychaeta : Spionidae) on an intertidal sand flat
Abstract Inhibition of larval settlement by a dense assemblage of established adults was examined by observing natural and experimental abundance patterns of two polychaete species on an intertidalExpand

Competitive Bioturbators on Intertidal Sand Flats in the European Wadden Sea and Ariake Sound in Japan
Distribution patterns and changes in abundance of macrozoobenthic species on intertidal sand flats have often been interpreted in terms of the physical environment, such as tidal level, sedimentExpand

Intraspecific behaviors and major cheliped sexual dimorphism in three congeneric callianassid shrimp
Decapod callianassid shrimps are usually solitary occupants of their burrows. They are known to show distinct sexual dimorphism of the major cheliped, which is used as a weapon for intraspecificExpand

Complex vertical migration of larvae of the ghost shrimp, Nihonotrypaea harmandi, in inner shelf waters of western Kyushu, Japan
Abstract The position of meroplanktonic larvae in the water column with depth-dependent current velocities determines horizontal transport trajectories. For those larvae occurring in inner shelfExpand

Decrease of Abalone Resources with Disappearance of Macroalgal Beds Around the Ojika Islands, Nagasaki, Southwestern Japan
ABSTRACT Because abalone feed mainly on macroalgae, the disappearance of macroalgal beds would have negative effects on abalone. We investigated the relationship between abalone resources andExpand

Larval stages of the bluefin tuna blood fluke Cardicola opisthorchis (Trematoda: Aporocotylidae) found from Terebella sp. (Polychaeta: Terebellidae).
We found aporocotylid larval stages (sporocysts and cercariae) from five individuals of terebellid polychaete Terebella sp., which were collected from seabed substrate and ropes and floats attachedExpand
