Predatory 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...

Effects of copepod foraging behavior on predation risk: An experimental study of the predatory copepod Pareuchaeta nowegica feeding on Acartia clausi and A. tonsa (Copepoda)

The effect of foraging behavior on predation risk was studied by exposing the two small Calanoid copepods Acartia clausi and Acartia tonsa to 0 or 1 ppm (1,500 cells ml-l) of the diatom Thalassiosira weissfogii and to presence of the predator Pureuchaeta norvegica. In filtered water, predation rate was the same on the two species. In algal suspension, predation rate on A. clausi was half that i...

Effects of food on bacterial community composition associated with the copepod Acartia tonsa Dana.

The estuarine copepod Acartia tonsa naturally carried diverse strains of bacteria on its body. The bacterial community composition (BCC) remained very conservative even when the copepod was fed different axenic algal species, indicating that the food per se did not much affect BCC associated with the copepod. In xenic algal treatments, however, copepod-associated BCC differed with each alga fed...

Sublethal stress: Impact of solar UV radiation on protein synthesis in the copepod Acartia tonsa.

Aquatic organisms respond to environmental challenges such as thermal stress with the rapid induction of highly conserved polypeptides known as stress proteins or heat shock proteins (Hsps). Solar ultraviolet radiation (UVR, 280-400 nm) is an important environmental stressor in marine ecosystems. Here, we present results of experiments conducted with the marine copepod Acartia tonsa to follow t...

Toxicity of nickel in the marine calanoid copepod Acartia tonsa: Nickel chloride versus nanoparticles.

Nickel compounds are widely used in industries and have been massively introduced in the environment in different chemical forms. Here we report the effect of two different chemical forms of nickel, NiCl2 and nickel nanoparticles (NiNPs), on the reproduction of the marine calanoid copepod Acartia tonsa. The behavior of nickel nanoparticles was analyzed with different techniques and with two pro...
