Evolutionary history of the Afzelia Smith (Leguminosae Caesalpinioideae) complex in forest and savannah ecosystems of tropical Africa ; Historia evolutiva del complejo Afzelia Smith (Leguminosae Caesalpinioideae) en ecosistemas forestales y de sabana de África tropical ; Histoire évolutive du complexe Afzelia Smith (Leguminosae - Caesalpinioideae) dans les écosystèmes forestiers et savanicoles d’Afrique tropicale

The genus Afzelia Smith includes seven African tree species: two are found in the Zambezi region, one in the Sudanian region and four in the Guinea-Congo region. These taxa are commercially valuable but because they are difficult to distinguish, they are marketed under the same commercial name, either “doussié” or “afzelia”, which complicates sustainable management of their populations.The aim of this PhD thesis is to characterize the evolutionary history of the Afzelia genus. More specifically, our study aims to: (i) assess the extent of morphological divergence within the Afzelia genus and d... Mehr ...
