Facilitating management of marine and coastal biological diversity in the region through, for example, provision of information through the database (including GISbased information), provision of advisory services, etc. 3 Our thanks to the Sloan Foundation for their generous support, without which this workshop could not have taken place, to the workshop participants for the considerable effort they put into their presentations and written reports and to our host institutions for allowing us to become involved in this important exercise. The workshop also considered what actions could be taken to address shortcomings in the state of knowledge surrounding marine biological diversity in sub Saharan Africa, and to mitigate current threats to this diversity. It is our hope that these discussions will ultimately result in the establishment of a broader Action Programme to address these vital issues, and a committee was appointed at the conclusion of the meeting to take these matters forward. Contribution à la faune des Annélides polychètes du Sénégal. Inventoried green algae correspond to 1.4% of the number of species described in the world, 6 brown algae (Phaeophyta) 1.2% and red algae (Rhodophyta) 1.5%. The main threat to algae is the pollution of marine and brackish waters in Cote d’Ivoire. crassipes, Lemna sp., Spirodela sp., Wolfia sp., et Wolffiella sp. Information dissemination and communication, including the establishment and consolidation of the network of biodiversity researchers and professionals, and an electronic database of biodiversity and taxonomic resources (including species inventories, catalogues of museum holdings, lists of taxonomists working on different groups, etc.). Developing human, institutional and infrastructural capacity for furthering knowledge of marine and coastal biological diversity in the region through, for example, development of an MSc course in taxonomic and biodiversity studies, partnering with other institutions in exchange programmes, etc.

In addition, the partitioning of algae in the marine and brackish waters of Cote d’Ivoire needs to be understood. Aquatic macrophytes There are 327 species of aquatic and semi-aquatic macrophytes belonging to 74 families in Cote d’Ivoire. Swamp forests are found in poorly drained soils that are periodically inundated by fresh water.

The workshop was an initiative of the Census of Marine Life (Co ML) Programme, which has sponsored a series of other similar regional workshops, aimed at documenting the state of knowledge of marine biodiversity and at establishing regional networks of researchers to promote and co-ordinate future research in the discipline. Previous workshops have been held in Southeast Asia (Phuket, October 2001) and in South America (Conception, October 2002), and another is proposed for India in December 2003. The sub-Saharan African workshop was convened jointly by the Zoology Department at the University of Cape Town, the International Ocean Institute in Southern Africa (University of the Western Cape), and the South African Institute for Aquatic Biodiversity, and was supported financially by the Alfred P Sloan Foundation.

Introduction Located in the Gulf of Guinea, with an area of 322 465 km², Cote d’Ivoire (4°30’ and 10°30’N and 2°30’ and 8°30’W) is bounded by the Atlantic Ocean in the south, Liberia in the south east, Guinea in the northwest, Burkina Faso in the north and Ghana in the east. Annélides Polychètes de la Casamance rapportées par M. The continental shelf is narrow, with a width that varies between 9 and 18 miles, with a mean of 13 miles. Marine algae Microphytes belong to two major groups: the phytobenthos (mainly Cyanophyceae and Bacillariophyta) and phytoplankton (mainly Cyanophyceae, Diatomophyceae, Pyrrhophyceae, Chlorophyceae and Euglenophyceae). Different types of human activities are conducted in the region, notably agriculture, power generation, timber exploitation, sand extraction, and various industries (e.g. Several ports are located in this region, including the political capital Abidjan. A total of 1241 microphyte species have been recorded including 113 species of Cyanophycaeae. These zones often include ferns such as Nephrolepsis biserrata and Caratopteris cornula. Mangroves in Cote d’Ivoire comprise three species (Rhizophora racemosa, Avicennia germinans, Conocarpus erectus).
