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...

We developed a method to extract environmental DNA and amplify target portions of the internal transcribed spacer region (ITS) of the ribosomal gene (ITS1-5.8S-ITS2) from individual species of oligotrich and choreotrich ciliate microzooplankton. To date, we have laband field-tested primers specific to the tintinnid Favella ehrenbergii, the oligotrich Laboea strobila, and the choreotrich Strombi...

Planktonic copepods exhibit rapid escape behavior in response to hydrodynamic disturbances. Small disturbances of brief duration were produced by a piezoelectric transducer moving a small cylinder. The escape responses of free-swimming adult males and females of the copepods Acartia tonsa and A. lilljeborgii were recorded using high-speed video and quantified using computerized motion analysis ...

Background. Climate change concurrent with anthropogenic disturbances can initiate serial changes that reverberate up the food chain with repercussions for fisheries. To date, there is no information available concerning the combined effects of global warming and human impacts on tropical marine food webs. While temperate copepods respond differently to warming and environmental stressors, the ...

This paper presents information from different sampling surveys carried out along the Santa Catarina coast in order to outline the biogeographical characteristics of the zooplankton in this region and identify species or groups of species with potential use as bioindicators. Based on a checklist of species of the zooplankton community in the state, it was observed that, in the warmer months of ...
