Copepods can feed on, and may regulate, the blooms of harmful algae (HA), also facilitate dinoflagellate by inducing toxin production through selective grazing. However, exposure to HA cause mortality reproductive impairment in copepods, with detrimental effects at population-scale. Here we present profile dinoflagellate, Alexandrium catenella (formerly tamarense ), examine how it affects survi...

We studied the response of the copepods Acartia tonsa and Temora longicornis to spatial gradients of flow velocity and fluid density to determine whether the presence of physical gradients initiated local search for resources or promoted aggregation. Two additional species of copepods, Candacia ethiopica and Labidocera madurae, were also exposed to velocity gradients. A plane jet flume apparatu...

 Mnemiopsis leidyi which was accidentally introduced into the Caspian Sea in 1999 and since then has colonized extensively. The horizontal distribution of M. leidyi and dominant mesozooplankton species was investigated in the south western Caspian Sea during February, May, July and November 2008. The average number and biomass of M. leidyi were in the same range (ca 200 individuals.m-3 (...

Dentro del zooplancton, los copépodos son uno de principales consumidores fitoplancton. Por tanto, estos organismos potenciales las especies dinoflagelados que producen toxinas. En este sentido, se estudiaron efectos floraciones algas nocivas (FAN) sobre la zona oriental golfo Cariaco, Venezuela. Se recolectaron muestras mensuales junio 2009 a mayo 2010, en nueve estaciones distribuidas tres zo...
