Abstract
In Senegal, Mosses constitute a large and diverse systematic group. This work is a contribution to the knowledge of Bryophyta in the herbaria of Senegal. It specifically proposes to determine the structure of the Bryophyta on the prospected sites in order to provide basic knowledge for a better sustainable management. This study is carried out in the first place in the herbaria of the University Cheikh Anta Diop of Dakar/Senegal: the herbarium of the Institut Fondamental d'Afrique Noire Cheikh Anta Diop (IFAN) and the herbarium DAKAR of the Department of Plant Biology of the Faculty of Sciences and Techniques. Secondly, a consultation of different checklists and databases was conducted to collect more information. This research work on the flora of the mosses allowed us to identify a total of 70 species divided into 44 genera, 24 families and 12 orders. The orders Hypnales, Dicranales and Hookeriales are the most represented. Bryaceae are dominant followed by Pottiaceae, Calymperaceae, Dicranaceae and Hypnaceae. The genera Fissidens, Calymperes, Bryum, Gemmabruym and Leucoloma are more diversified. These results are important for the conservation of the environment and the enhancement of plant biodiversity in Senegal.
Highlights
Bryophytes in the strict sense (Bryophyta) represent about 10,000 [21] to more than 13,000 species [19] in 845-866 genera [20, 12] and six classes worldwide
The richness of the Institut Fondamental d'Afrique Noire Cheikh Anta Diop (IFAN) herbarium collection is due to the fact that it is a regional level herbarium receiving a lot of samples from African countries (French Guinea, Chad, Gabon, Uganda, Sao Tome and Principe) and even outside the African continent (Guadeloupe)
It shows in particular that knowledge on the bryophytes of Senegal is dispersed with three lists of flora
Summary
Bryophytes in the strict sense (Bryophyta) represent about 10,000 [21] to more than 13,000 species [19] in 845-866 genera [20, 12] and six classes worldwide. There is growing evidence that mosses are at the highest level of diversity in their evolutionary history [35]. This fairly recent diversification of mosses is probably related to the advent of Angiosperm forests offering a wide range of habitats (the bulk of moss diversity in tropical rainforests). Mosses are rather small organisms, their morphology is relatively complex. Throughout their evolutionary history, mosses have undergone repeated morphological reduction and simplification [34], often as a result of colonization of specialized, xeric or ephemeral habitats [53].
