“…Within such strong chemical gradients, distance chemoreception (smell) works optimally (Atema 1996). This enables Brachionus to track algal patches precisely (Charoy 1995;Ignoffo et al 2005), and to deplete such patches within a short time span (Ignoffo et al 2005), which is in line with our own observations. Contact chemoreception (''taste'') does not seem to have a very high resolution in B. calyciflorus (DeMott 1986;Rothhaupt 1990a;Starkweather 1995), but B. calyciflorus has a clear size preference when offered differentially sized particles (DeMott 1986;Rothhaupt 1990a; this study).…”

We studied how chemicals obtained as filtrates from algal monocultures (algal chemicals) and from rotifer cultures with or without algae (rotifer chemicals) affected feeding rates of the rotifer Brachionus calyciflorus on its food algae, both directly and indirectly (through chemical-induced changes in algal morphology). Algal chemicals had a strong stimulating effect on the feeding rate of B. calyciflorus, but these effects were counteracted by rotifer chemicals. In functional response experiments, rotifer chemicals lowered maximum ingestion rates and had strong effects on assimilation rates and assimilation efficiencies of B. calyciflorus, probably due to the release of unspecific (auto)toxic metabolites. Furthermore, rotifer chemicals induced colony formation in the food alga Scenedesmus obliquus. Above the optimum particle size for ingestion by B. calyciflorus, larger algal colony sizes increased the food-handling time, thus lowering ingestion and assimilation rates. Through their effects on trophic interactions, infochemicals may play a role in structuring and the functioning of aquatic food webs.

“…Furthermore, temperature and food in the epilimnion are useful for the zooplankton in this region, but the highest fish predation is seen at this layer, as well. Trade-offs exist between feeding and predator avoidance (Burns and Mitchell, 1980;Masson et al, 2001;Andersen et al, 2004;Ignoffo et al, 2005). The composition and dynamics of the zooplankton community are affected by interspecies competition and selective predation pressures.…”

Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals

To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and microzooplankton (rotifers). Concentrations of particulate organic matter (POM in suspension or in aggregates), of dissolved organic matter (DOM), and of dissolved inorganic nutrients were monitored over 8 days. The presence of rotifers enhanced the remineralization of ammonium and phosphate, but not dissolved silicon, from the biogenic particulate matter, up to 40% of which became incorporated into aggregates early in the experiment. Added calcite resulted in rates of excretion of ammonium and phosphate by rotifers that were depressed by 67% and 36%, respectively, demonstrating the potential for minerals to inhibit the destruction of POM by zooplankton in the water column. Lastly, the presence of the rotifers and added calcite minerals resulted in a more rapid initial rate of aggregation, although not a greater overall amount of aggregation during the experiment
