A new species of Acartia (Copepoda, Calanoida) from the Yellow Sea
A new species (Acartia hongi) of Acartia (family Acartiidae) predominating in the Korean coastal waters of the Yellow Sea is described. This species closely resembles Acartia bifilosa, from which it can be easily distinguished by the co-occurrence of the following morphological characters: the absence of rostral filaments in both genders; the terminal spine on the female fifth leg toothed only ...

متن کاملPredatory and suspension feeding of the copepod Acartia tonsa in turbulent environments
The copepod Acartia tonsa exhibits 2 different feeding modes: when feeding on small phytoplankton cells it sets up a feeding current and acts as a suspension feeder; when feeding on motile prey it acts as an ambush feeder. We examined experimentally the effects of small-scale turbulence on feeding rates in these 2 modes. The different feeding behaviours were triggered by offering the copepods d...
متن کاملToxicity of ZnO nanoparticles to the copepod Acartia tonsa, exposed through a phytoplankton diet.
Zinc oxide (ZnO) nanoparticles are being increasingly utilized in a variety of products and applications and are therefore commonly discharged into aquatic environments, increasing exposure and potentially impacting aquatic organisms. Zinc oxide nanoparticles can depress growth of some marine phytoplankton, and several examples of nanoparticle trophic transfer have been documented, although not...
متن کاملMecynocera clausi I . C . Thompson , 1888 ( Copepoda : Calanoida ) is a paracalanid
Mecynocera clausi I.C. Thompson, 1888 is the type genus and species of the monotypic family Mecynoceridae Andronov, 1973. Based on the first description of male mouthparts of Mecynocera clausi Thompson, 1888 (Copepoda: Calanoida), evidence is presented for the transfer of this genus and species to the Paracalanidae Giesbrecht, 1893. Thus, Mecynoceridae Andronov, 1973 becomes a junior synonym of...
