Vulnerability of African Rosewood ( Fabaceae) natural stands to climate change and implications for silviculture in West Africa.

is a native tree species of the Guineo-Sudanian and Sudano-Sahelian zones where natural stands are under constant pressure and heavily exploited for timber, animal feeding and others uses. A part from the overexploitation, climate change could also become a serious threat to the species natural distribution. For that purposes, this study aims to assess the vulnerability of potential niche to climate change within its natural distribution area in West Africa.

A first checklist of the Pteridophytes of Togo (West Africa).

Background: The present work proposes, for the first time, a study exclusively focused on the diversity of Pteridophytes in Togo.The study was based on fieldwork that resulted in 869 new collections gathered between 2013 and 2017 in the country and on yet existing herbarium specimens kept at the Herbaria of Lomé and Paris. Thus, a total number of 1092 specimens collected throughout the country served as a basis for this work, to which were added the known, published occurrences of Pteridophytes for the country.

The Pteridaceae family diversity in Togo.

Background: The Pteridaceae family is the largest fern family in Togo by its specific and generic diversity. Like all other families of ferns in the country, Pteridaceae are poorly studied and has no identification key. The objective of this study is to perform a taxonomic revision and list establishment of this family of leptosporangiate ferns in the light of current available knowledge about the family.
