A Biodiversity Reference Center in Ghana for West African Fresh and Brackish-Water Fishes OceanDocs
Gourene, G.; Provost, P.; Teugels, G.G.; Fermon, Y.; Bailly, N.; Meunier, F.; Abban, E.K..
Renewable natural resources (RNR) are a major source of socio-economic development potential in all developing countries, if they can be conserved, developed and sustainably exploited. For strategic conservation and sustainable exploitation strategies to be implemented, a knowledge of biodiversity at various levels within these RNR has to be investigated and documented in an internationally accepted manner, and preferably as close as possible to the habitat of the resources. However, human and material resources available in developing countries are currently neither sufficiently trained nor sufficient to undertake the appropriate studies. Meanwhile, various forces continue to deplete RNR and their inherent biodiversity. An attractive approach towards...

Critère pratique pour distinguer deux poissons chats africains Clarias anguillaris et C. gariepinus (siluriformes; clariidae) IRD
Bénech, Vincent; Teugels, G.G.; Gourene, G..
A useful character to distinguish two African catfishes, #Clarias anguillaris$ and #C. gariepinus$ (Siluriformes; #Clariidae$). The morphology of the cleitrhrum appears as a useful character to distinguish the closely related catfish species, #Clarias anguillaris$ and #C. gariepinus$ in the Central Niger Delta. Elsewhere, the difference seems less distinct, although the presence of a pointed cleithrum is typical for #C. gariepinus$. (Résumé d'auteur)

Le genre #Poecilothrissa$ est synonyme du genre #Microthrissa$, au sein duquel il a été reconnu comme un sous-genre distinct. Cinq espèces valides ont été retenues. Deux espèces nominales ont été mises en synonymie. Enfin, #Microthrissa normanae$ a été rapporté au genre #Pellonula$, et mis en synonymie avec #P. leonensis$. (Résumé d'auteur)
