We present a model for the growth and development of copepods based on the simple assumption that a constant fraction of assimilated carbon is invested in the formation of a new carapace. The individual molts into the next stage when the weight of the accumulated carapace building bricks is a fixed fraction of the body mass at the beginning of the stage. This simple stage-transition coordinatin...

The vertical distribution of copepod (>64 pm) grazing was mcasurcd on the equator at 14O”W during March/ April (19 d) and October 1992 (21 d). El NiAo conditions prevailed during the March/April time series. Hydrographic variables were similar to the climatological mean during the October time series.,We found higher weight-specific copepod filtration rates in October when mixed-layer temperatu...

copepods are the main zooplankton assemblages in most tropical and semi-tropical estuaries. in this research, copepod population dynamics were investigated in helleh river estuary, persian gulf during four seasons beginning from summer 2011 to spring 2012.  samples were taken using plankton net with mesh size of 140 µm and vertical towing from 5 fixed-stations in mid-season. results showed that...

Copepods are small crustaceans that dominate most zooplankton communities in terms of both abundance and biomass. In the polar oceans, a subset large lipid-storing copepods occupy central positions food web because their important role linking phytoplankton microzooplankton with higher trophic levels. this paper, we generated high-quality de novo transcriptome for Rhincalanus gigas, largest—and...

The diet of Antarctic silverfish Pleuragramma antarcticum was evaluated by examining stomach contents of specimens collected in the Ross Sea (71°-77° S; 165°-180° E) in January to March 2008. Pleuragramma antarcticum (50-236 mm standard length, L(S)) and prey items were analysed for stable-isotopic composition of carbon and nitrogen. According to index of relative importance (I(RI) ), which inc...

Stable carbon isotopes were used to determine the contribution of emergent demersal zooplankton to the diet of the scyphozoan jellyfish, Catostylus mosaicus, at Smiths Lake, New South Wales, Australia. A preliminary study in 2004 indicated that there was no difference in the δC of ectodermal tissue and mesoglea of the medusae. In 2005, medusae and zooplankton present during the day and night we...
