Vertical migration and feeding behavior of Calanus paci$cus females during a phytoplankton bloom in Dabob Bay, U.S
We report the first seasonal time-series observa-tions of porewater composition obtained for deep-sea sedi-ments. We observed considerable temporal variability of O,,NO,-, and Mn2+ profiles at the French JGOFS site DYFA-MED (western Mediterranean) in response to a pulsed inputof organic matter. A delivery of reactive organic matter rep-resenting only 1% of the average or...

15 صفحه اولEffects of Size and Concentration of Food Particles on the Feeding Behavior of the Marine Planktonic Copepod Calanus Pacificus
When adult females of Calanus pacificus are fed on monospecific cultures of centric diatoms which grow as single cells, a predictive relationship is found between feeding behavior of the copepods and size and concentration of food particles. Ingestion rate of copepods increases linearly with cell concentration up to a maximal rate. This maximal ingestion rate, expressed as carbon, is the same f...
متن کاملPoststarvation feeding and swimming activity in Calanus pacijkus and Metridia pacijica
Gut fluorescence analysis of Calanus paczjkus and Metridia pacijica is used to describe variation in food intake rate at time scales of one to several hours. The animals are starved before each experiment, then exposed continuously to phytoplankton cultures. Variability of gut fullness is large (order IO-fold) between individual copepods captured at the same time and is about proportional to th...
متن کاملThe impact of polystyrene microplastics on feeding, function and fecundity in the marine copepod Calanus helgolandicus.
Microscopic plastic debris, termed “microplastics”, are of increasing environmental concern. Recent studies have demonstrated that a range of zooplankton, including copepods, can ingest microplastics. Copepods are a globally abundant class of zooplankton that form a key trophic link between primary producers and higher trophic marine organisms. Here we demonstrate that ingestion of microplastic...
