Diversity of African fish : heritage of evolution / The inland water fishes of Africa : diversity, ecology and human use...
Early life stages of dominant West African pelagic fishes, most of which are commercially important, are rarely studied especially in Senegalese and Mauritanian coastal waters. The aim of the present study was to examine the horizontal distribution of pelagic fish eggs of European sardine (Sardina pilchardus), anchovy (Engraulis encrasicolus), roun...
La biologie et l'écologie des bénitiers Tridacna maxima (Röding 1798) est sous influence de leur environnement. Ici, nous avons mesuré plusieurs facteurs environnementaux : taux de sédimentation, hydrodynamisme ainsi que structure de l’habitat, et avons examiné leur influence sur la densité, le coefficient de variation (CV) et le taux de survie des...
Le blanchissement corallien est une conséquence dramatique du réchauffement climatique qui menace les récifs et la biodiversité mondiale. A travers un cas d’étude sur les îlots du lagon Sud-ouest de la Nouvelle-Calédonie, nous avons planifié un réseau d’Aires Marines Protégées conservant des zones refuges, ayant une sensibilité au stress thermique ...
The utility of taxonomic and functional approaches in assessing the structure of fish communities is tested in the hypersaline estuary of the Casamance river using data from surveys of commercial fisheries conducted between April and July of 2005. Both taxonomic and functional diversity decrease from downstream to upstream regions of the estuary. I...
Patterns of bivalve larvae dispersal in the deep Ahe atoll lagoon was studied by using a numerical 3D transport model (MARS3D) coupled with a vertical swimming sub-model, forced mainly by tide and wind-induced currents. The simulations were validated against observations of larval dispersal monitored several days throughout the lagoon. Connectivity...
