S. setigera is a "mbep ou mbepp" gum producing species requested on the national and international market. Its population is poorly known and its dynamics uncontrolled. This study aims to characterize the current status of woody vegetation particularly S. setigera in Malem Niani and Daoudi, Tambacounda, Senegal. The sampling was stratified according to the different vegetation units. In each unit, transects were implemented. Along each transect, 900 m² samples were made with an equidistance of 50 m. The floristic analysis revealed 30 species diversity. Combretaceae family is the richest one. Detrended Correspondence Analysis (DCA) shows woody vegetation heterogeneity through evidence of four floristic groups with a large presence of S. setigera. Woody stems distribution inside groups according to height and diameter is similar in both sites while S. setigera distribution shows occurrence of large diameters in Malem Niani and Daoudi. This study evidences species diversity in both sites. Among these species, economic and social interest ones like S. setigera as a real forest resource and ecological importance taxa were met. Therefore, this study contributes to a better knowledge of S. setigera populations’ status in Tambacounda and should help for their upcoming management.

The objectives of the study were to determine the specific richness and abundance of the fish population of Joal Fadiouth's Protected Marine Area (MPA) in Senegal. To obtain a representative view of the spatial distribution of the fish fauna of the Joal-Fadiouth MPA, we chose to sample at three sites in particular the Gaskel, Church and Mbar Assane stations. Experimental fisheries are conducted between 2014 and 2015 during the four hydrological seasons of each year, including cold (April), cold warm (June), warm (August) and cold (November). Three types of fishing gear, namely a purse seine (ST), an encircling mesh (FME) mesh 12 mm stretched and a longline (P) were used separately from one station to another, each station. It allowed us to identify the different species and their distribution in the MPA. A total of 70 species were recorded between the different experimental fishing stations in both zones. These species are divided into 60 genera belonging to 38 families. The species of Sciaenidae and Carangidae are the most numerous with respectively 9 and 7 species, followed by Sparidae, Clupeidae and Tetraodontidae with 5 species for the first and 3 species for each of the other two.
