Taxonomic review of three Japanese species of edible jellyfish (Scyphozoa: Rhizostomeae)
It is proposed to revive the original name Nemopilema nomurai Kishinouye 1922 from the more com monly used Stomolophus nomurai, and the taxonomic position of N. nomurai within the Scapulatae is discussed.
Synopsis of edible jellyfishes collected from Southeast Asia, with notes on jellyfish fisheries
Based on sampling of specimens and field observations on jellyfish fisheries in Malaysia, Indonesia, and Myanmar, six trade types of edible jellyfish were identified and the proper scientific names…
Impacts of ontogenetically migrating copepods on downward carbon flux in the western subarctic Pacific Ocean
Dispersion of artificial caesium-134 and -137 in the western North Pacific one month after the Fukushima accident
(about 85 PBq) (WHO, 1989). Large amounts of water to cool the fuel rods was supplied and this procedure increased the amount of water contaminated with radionuclides, and the contaminated water…
Evaluation of the bioactivities of water-soluble extracts from twelve deep-sea jellyfish species
A high incidence of water-soluble bioactive substances occurring in these deep-sea jellyfishes was revealed and all the heat-treated and the methanol-treated crude jellyfish extracts lost their bioactivities.
Impacts of the wintertime mesozooplankton community to downward carbon flux in the subarctic and subtropical Pacific Oceans
Horizontal distribution of Fukushima-derived radiocesium in zooplankton in the northwestern Pacific Ocean
The magnitude of the 9.0 Tohoku earthquake and the ensuing tsunami on 11 March 2011, inflicted heavy damage on the Fukushima Dai-ichi nuclear power plant (FNPP1). Fission products were emitted,…
Seasonal variations in the nitrogen isotopic composition of settling particles at station K2 in the western subarctic North Pacific
Intensive observations using hydrographical cruises and moored sediment trap deployments during 2010 and 2012 at station K2 in the North Pacific Western Subarctic Gyre (WSG) revealed seasonal changes…
Possible association of diazotrophs with marine zooplankton in the Pacific Ocean
This study is the first systematic study of zooplankton‐associated diazotrophs, covering a large area of the open ocean, which provide a clue to further study of a possible new hotspot of N2 fixation.
Seasonal variability in carbon demand and flux by mesozooplankton communities at subarctic and subtropical sites in the western North Pacific Ocean
Mesozooplankton carbon demand in surface and mesopelagic layers was higher at K2 than S1, and an excess of demand to primary production and sinking POC flux was found during some seasons at K 2, and it is proposed that this demand was met by supplementary carbon sources such as feeding on protozoans and fecal pellets at the surface and carnivory of migrants at mesopelsagic depths.
