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...

As dominant members of marine mesozooplankton communities, copepods play critical roles in oceanic food webs and biogeochemical cycling. Despite the ecological significance of copepods, little is known regarding the causes of copepod mortality, and up to 35% of total copepod mortality cannot be accounted for by predation alone. Viruses have been established as ecologically important infectious ...

Introduction The first part of this appendix, presented in Bremerhaven in January 2001, entitled “Using remote sensing to determine estimates of secondary production” detailed how satellite derived estimates of sea surface temperature (SST) and chlorophyll were used as an input into the copepod egg production model of Prestidge et al. (1995). The model was run for two genera of copepod namely C...

Three strains of the chain-forming diatom Skeletonema marinoi, differing in their production of polyunsaturated aldehydes (PUA) and nutritional food components, were used in experiments on feeding, egg production, hatching success, pellet production, and behavior of three common planktonic copepods: Acartia tonsa, Pseudocalanus elongatus, and Temora longicornis. The three different diatom strai...

Through the use of mesocosm experiments, we show that an unusually early spring phytoplankton bloom can be induced by intermittent high-light periods. We performed mesocosm experiments where plankton assemblages from Kiel Bight (Western Baltic Sea) received a light regime based on the natural seasonal irradiance dimmed to 43% of surface irradiance of cloudless days, starting with irradiance lev...
