| La première réunion du Groupe de travail régional AEP s’est tenue du 27 au 30 janvier 2009 à Mombasa, Kenya, en même temps qu’un Atelier sur la méthodologie d’évaluation du risque écologique. Vingt participants des pays du sud-ouest de l’océan indien (SWIO), du Projet des pêches du sud-ouest de l’océan Indien (SWIOFP), du Projet sur les larges écosystèmes marins des courants d’Agulhas et de Somali (ASCLME), du Comité scientifique de la Commission des pêches du sud-ouest de l’océan Indien, de l’Unité d’exécution de la Convention de Nairobi/PNUD, de la Commission de l’Union africaine et de la FAO. Le Groupe de travail régional (GTR) est une structure d’exécution placée sous le Projet AEP-Nansen GCP/INT/003/NOR qui sert de forum pour la formation sur... |

| Il est connu que les ports soumis à un trafic maritime intense réceptionnent éventuellement les eaux de ballast des navires en provenance de diverses contrées océaniques. De part le monde, le transfert et l’invasion de plusieurs espèces nuisibles via le déversement des eaux de ballast et le fouling des coques des navires ont été amplement mis en cause ces derniers temps. Ces introductions peuvent causer de nombreux dégâts aux secteurs avoisinants et notamment dans les zones de production des coquillages surtout si les espèces introduites sont constituées de phytoplancton toxique. Au terme de 4 années de suivi de la qualité phytoplanctonique des milieux portuaires du golfe de Gabès, nous avons pu inventorier certaines espèces toxiques pour la plupart... |

| Time-series of condition factor (CF) and gonadosomatic index (GSI) were generated using general linear models (GLM) for sardine Sardinops sagax stocks in the northern and southern Benguela ecosystems over the period 1984–1999. During this period the biomass of sardine in the northern Benguela remained at relatively low levels of <500 000 tons, whereas that of southern Benguela sardine increased 40-fold to 1.3 million tons. The GLMs explained 27 and 45% of the observed variation in CF, and 32 and 28% of the observed variation in GSI, for sardine in the northern and southern Benguela subsystems respectively. Whereas the sardine CF in the northern Benguela remained stable over time, that for the southern Benguela stock declined steadily during the study... |

| Mangrove ecosystems on the coast of Cameroon are valuable both for their contributions to local livelihoods and the globally important biodiversity that they contain. However, these areas are threatened by a number of development pressures as well as unsustainable management and harvesting practices of the local communities living there. This project aims to strengthen protection and reduce degradation in these areas by supporting inter-sectoral co-ordination and collaboration (within an agreed national framework) and by helping local communities to redirect local economic activities towards activities that both improve their livelihoods as well as assist with the conservation of globally important biodiversity found in these areas. At the national level,... |

| Mangrove forests are unique ecosystems which provide a range of important goods and services. However, they are suffering high rates of destruction around the world, and will be one of the first ecosystems affected by the predicted sea level rise. This project aims to establish re-planted experimental plots of mangroves in cleared areas. Experimental treatments will consist of plots of three different tree species, along with all possible multi-species mixtures and unplanted controls. Volunteers will assist in planting mangroves, and in measuring a range of biological and physical parameters relevant to important ecosystem functions, such as productivity and growth rates, susceptibility to disease, faunal abundance (of fish and crabs) and sedimentary... |

| Se estudió la diversidad y distribución de la macro- y meiofauna y los rasgos funcionales de nemátodos marinos en dos sitios y cuatro hábitats dentro del ecosistema arrecifal de Punta Francés, Isla de La Juventud, Cuba. Los hábitats seleccionados fueron: seibadal, arena, coral muerto y fondo duro, y se muestrearon en dos sitios dentro del arrecife (Punta Francés y Cabezo de Moya) en Junio del 2010. Se identificaron y contaron los organismos de la macro- y meiofauna en las muestras; los nemátodos fueron identificados hasta especie, se calculó su tamaño y biomasa y se clasificaron en grupos tróficos. Los hábitats de coral muerto y fondo duro por su heterogeneidad y cubierta de césped de algas tuvieron macro- y meiofauna más diversa. La... |

| Le terme mangrove se réfère habituellement à un complexe de zones humides influencé par les marées et constitué de forêts marécageuses et autres habitats associés dans la zone intertidale sous les latitudes tropicales et subtropicales. Les écosystèmes forestiers de mangrove subissent des dégradations anthropiques de toutes sortes et de diverses amplitudes. La pression démographique provoque leur destruction et son influence s’accentue dans des zones non protégées, surtout au voisinage des agglomérations où les problèmes fonciers et la pauvreté poussent les populations à occuper des espaces libres à faibles coûts. Dans sa volonté d’assurer une gestion durable et participative des mangroves au Cameroun, le Gouvernement à travers le Ministère de... |

| There is an international consensus, expressed in the Convention on Biological Diversity, World Summit on Sustainable Development, and Millennium Ecosystem Assessment, that biodiversity at all levels – genetic, species and ecosystem – have a critical role in sustaining livelihoods and human development. They underpin and make possible all forms of economic activity. Damage to components of biodiversity have economic consequences, the impacts of which fall most heavily on the poor. In few contexts is this as clear as in the case of mangrove ecosystems and their dependent human populations. Mangroves support livelihoods in providing habitat for food species, timber for dwellings, cooking and heat, and many other subsistence and commercial activities.... |

| The structure of demersal fish assemblages on the continental shelf and upper continental slope of the Gulf of Guinea is described. Community structure is determined primarily by depth and type of sediment on the seabed. Changes in the composition of the identified species assemblages over a 25-year period are examined. The dynamics of the assemblages are influenced by physico-chemical parameters of the water masses, mainly temperature, salinity and dissolved oxygen, which are periodically modified by the seasonal coastal upwelling that occurs in the western Gulf of Guinea. Increased irresponsible fishing operations (like the use of explosives) that lead to habitat alteration and other anthropogenic activities like oil and gas exploration which have the... |
