ABSTRACT
Located in the East of the complex of wetlands in southern Benin, the Lower Valley of Ouémé includes water bodies (Lake Nokoué, Lagoon of Porto-Novo, Sô and Ouémé rivers), relics of forest, mangroves, flooded savannas, grasslands, plantations, fields and fallows. Annual counts of waterbirds were conducted over a period of ten years. Eighty-seven species of waterbirds belonging to 48 genera, 19 families and 9 orders were recorded during the period 1998 to 2004 and 2008 to 2010. Correspondence analysis and discriminant analysis applied to matrices species / sites x years allowed determining two groups of waterbirds A and B established along a salt gradient. |
