Représentation pollinique de la végétation actuelle des zones humides du Sud-Est du Togo

Les mangroves togolaises, developpees principalement le long du chenal Gbaga reliant la lagune d\'Aneho au fleuve Mono ainsi que les formations inondables affiliees ont ete etudiees. Differentes formations vegetales ont ete identifiees et leur inventaire floristique effectue. L\'analyse pollinique des echantillons de vase et de surface preleves dans ces formations a conduit a l\'identification de plusieurs taxons polliniques. Les assemblages polliniques caracterisant les mangroves a faible salinite figurent dans ce travail, ainsi que leur diversite specifique. D\'apres les taux des taxons polliniques identifies et selon leurs correspondances avec les taxons floristiques recenses, le probleme de representativite pollinique a ete aborde. The togolese mangroves developed mainly alongside the channel Gbaga linking up the lagoon of Aneho to the Mono river and the flooding affiliate formation were studied. Various formations were identified and their floristic inventory carry out. The analysis of the pollinic contents of mud and surface samples of the formations led to the identification of several taxa. The pollinic assemblies characterizing the low salinity mangroves and their biodiversity were underlined in this work. According to the pollinic rates and the botanic taxa represented, the problem of pollinic representativeness was approached.
