We set up a survey involving comprehensive chemical analyses of phytoplankton and the simultaneous monitoring of the reproductive response of Calanus helgolandicus. Hatching success and larvae development of C helgolandicus were monitored weekly with

Variations of egg production rate (EPR), hatching success (HS), production of abnormal larvae (AL) and histology of gonads have been investigated with Calanus chilensis females sampled weekly, from late November to December 2004, at a station located

International audience; The food selectivity of tethered females of the copepod Calanus helgolandicus was examined by using the colorimetric approach. First, feeding behavior of the copepod did not show any differences between the red-color stained w

Observations of gonads and oocyte development stages (OS) have been achieved in Calanus helgolandicus females fed different algal diets and starved in filtered sea water under laboratory conditions during 8 days. The effects of 20 diets on egg produc

A growing body of evidence suggests that interleukin-1α (IL-1α) is present in invertebrates. Both invertebrate and human IL-1α can bind to invertebrate receptors and stimulate invertebrate immune functions. The present study shows that IL-1α incr

In recent years a negative influence of diatom-derived α,β,γ,δ-unsaturated aldehydes (PUA) on the reproductive success of copepods and invertebrates has been suggested. Since adverse chemical properties of diatoms would question the traditional v

Two double-labelling methods, Tunel+propidium iodide and Annexin V-FITC+propidium iodide, have been tested to diagnose cell degradation processes in N1–N2 nauplius stages produced by spawning females of the copepod Calanus helgolandicus fed either

Diatoms are small eukaryotic plants with over 10,000 known species, constituting one of the major components of the phytoplankton in freshwater and marine environments. Traditionally, they have been regarded as beneficial to the growth and survival o

α,β,γ,δ-Unsaturated aldehydes have gained increasing attention since 2,4-decadienal and 2,4,7-decatrienal were isolated from the diatom Thalassiosira rotula and characterized as cell antiproliferative metabolites. Structurally related α,β,γ,δ

A new tool, designed to measure the adductor muscle strength in juvenile oysters, is described. This instrument has been applied for the evaluation of muscle strength (F) in relation to dry weight of shell-free oysters, longitudinal (d1) and transver
