Hydrodynamic signal perception in the copepod Acartia tonsa
TLDR
It is suggested that A. tonsa cannot distinguish signals from those due to their own behaviour because they cause a similar spatial distributions of the signal across the body, and, hence, may detect predators at longer distances. Expand
Annual zooplankton succession in coastal NW Mediterranean waters: the importance of the smaller size fractions
TLDR
The results suggest the need for accurate samplings of the entire zooplankton assemblage when characterizing the structure and dynamics of zoopLanktonic communities. Expand
The ciliate-copepod link in marine ecosystems
TLDR
The results of a comparative, cross-ecosystem, analysis of the relative impor- tance of ciliates as carbon sources for copepod are shown, and the strength of the ciliate-Copepod trophic link is evaluated. Expand
Planktivorous feeding in calm and turbulent environments, with emphasis on copepods
TLDR
Turbulence has the largest effect on prey encounters for predators with low motility and long reactlon distances, and the potentially negatlve effects of turbulence on copepod feedlng currents, prey perception and capture success are explored. Expand
Predicting single and mixture toxicity of petrogenic polycyclic aromatic hydrocarbons to the copepod Oithona davisae.
TLDR
The results indicate that the many PAHs in an oil spill can be considered unambiguous baseline toxicants acting additively as nonpolar narcotics in copepods; hence, their individual and combined toxicity can be predicted using their octanol-water partition coefficient. Expand
Effect of heterotrophic versus autotrophic food on feeding and reproduction of the calanoid copepod Acartia tonsa : relationship with prey fatty acid composition
TLDR
The data do not show that ciliates and heterotrophic dinoflagellates are nutritionally superior prey for marine copepods, contrary to general expectations, and egg viability was correlated with ingestion of certain prey essential fatty acids. Expand
RNA content of copepods as a tool for determining adult growth rates in the field
TLDR
There was a good linear relationship between growth rate (estimated as egg production) and RNA contents of the adult copepods and the slope of the relationship was dependent on temperature. Expand
Effects of small‐scale turbulence on copepods: The case of Oithona davisae
TLDR
The response of O. davisae feeding to turbulence in the authors' experiments agrees with recent field observations on changes in the vertical distribution of Oithona as a function of wind-driven turbulence events, and the copepod seems to choose those depths where small-scale turbulence favors feeding. Expand
Prey switching behaviour in the planktonic copepod Acartia tonsa
TLDR
It is suggested that prey switching by copepod may provide survival windows for microzooplankters during blooms of net phytoplankton because predation pressure from the copepods is then less, and turbulence favours the selection of cillates as prey. Expand
Predatory and suspension feeding of the copepod Acartia tonsa in turbulent environments
TLDR
The findings suggest that prey selection in A. tonsa may be partly governed by turbulence in the ocean, and that ambush-mode feeding is much more dependent on turbulence than suspensionmode feeding. Expand
