During a survey of the freshwater diatom flora of the Senegal River, an unknown Placoneis species was observed that was initially identified as Placoneis gastrum. Detailed morphological analysis using both light and scanning electron microscopy observations revealed sufficient morphological differences to separate this species as Placoneis cocquytiae sp. nov. The new species is characterized by a rather broadly lanceolate to elliptic-lanceolate ...

We derive a new method to estimate the age specific incidence of an infection with a differential mortality, using individual level infection status data from successive surveys. The method consists of a) an SI-type model to express the incidence rate in terms of the prevalence and its derivatives as well as the difference in mortality rate, and b) a maximum likelihood approach to estimate the prevalence and its derivatives. Estimates can in ...

This research examines the surplus that Senegalese migrants realize in the country of arrival (Belgium) and that they transfer under the form of financial capital, goods and knowledge in one way or another to (close) family members in their country of origin (Senegal). In this study, these transfers are referred to as remittances. When the emphasis is being laid on the motives for sending remittances, the expectations of the household, the ...

This paper analyses the impact of men's international labour migration on the income-generating activities of the women who stay in their communities of origin. Previous research has reached mixed conclusions. Some find that men's migration discourages the economic participation of their spouses left behind, increasing women's dependence on them. In contrast, others argue that the resources generated by migration help women to develop new ...

Introduction. Tamarind (Tamarindus indica L.) belongs to the Fabaceae family; it is a multipurpose tree with slow growth. In order to help improve its growth and development, we assessed mycorrhizal diversity of tamarind parklands in Senegal. Materials and methods. Three sites of tamarind populations were sampled for each agro-ecological zone in Senegal: the Sahelian zone (i), Sahelo-Sudan zone (ii) and Sudan zone (iii). Soil and root samples ...

'Sexually transmitted diseases in the female population of Pikine, Senegal': The prevalence of some sexually transmitted disease is determined in 250 gynaecology patients and in 200 pregnant women seen in primary health centers in Pikine, Senegal. The main reason for consultation at gynaecology is infertility. Gonorrhoea and Chlamydia trachomatis infection are present respectively in 1.5% and 7% of pregnant women and in 4.4% and 7.6% of ...
