Zooplankton may at times graze cyanobacteria. However, their top-down effects are considered to be low, particularly in tropical regions dominated by small-size grazers that may be unable to consume efficiently filamentous or colonial species. Recent

Adult Vinciguerria nimbaria are the main prey of tuna during the tuna fishing season (late autumn and winter) in the equatorial Atlantic (0–4°N, and ~15°W). V. nimbaria trophic behavior in the fishing grounds was studied in relation to hydrobiolo

This project studied how meso- and macro-zooplankton communities (composition, abundance, and biomass) in the Senegal River Estuary varied in time and space depending on hydro-biological factors and human action. Samples were taken approximately ever

The trophic relationships between metazooplankton and natural particles were studied in May 2002 in the Senegal River Estuary (16 degrees N, 16 degrees W) in low water conditions (dry season). Environmental factors, micro-organism and metazooplankton

Tropical instability vortices are believed to modify the trophic food web by affecting plankton production. Such instabilities have been evidenced in a tuna fishing area of the Atlantic (10°–20° W and 2°–5° N). However, the origin of the tuna

Mesozooplankton biomasses, grazing rates, and metabolism (respiration, ammonium and phosphate excretion) were measured in the central Pacific (180°; 8°S–8°N) during the EBENE cruise, in October–November 1996. In the HNLC zone, the highest meso

Summary 1. Based on two mesocosm experiments and 10 in vitro predation experiments, this work aimed to evaluate the impact of nutrient supply and Chaoborus predation on the structure of the zooplankton community in a small reservoir in Cote d'Ivoire.

Micronekton is a major component of oceanic tuna diet. Within micronekton species, Vinciguerria nimbaria, was found to constitute the main forage fish for tuna in the [10–20° W, 0–5° N] area where a large seasonal tuna fishery occurs. The relat

Feeding behaviour of adult European anchovy (Engraulis encrasicolus) was studied in the Gulf of Lions (northwestern Mediterranean Sea) in relation to major abiotic and biotic factors. Observations were made during the main spawning period (summer) fo

Turbot larvae are transported towards coastal nursery areas and live in very shallow waters. Food availability is assumed to be an important factor that retains them in such areas. To study the effects of a biotic factor (food) and an abiotic factor
