Abstract
Background Invasive weeds pose a serious threat to agricultural systems worldwide and the management of such species requires information on their distribution. Objective This research work aimed at assessing the evolution in the distribution of Siaw weed across biogeographical zones in Benin as first step toward the development of management policy and to give insight into the threat it poses to agriculture and biodiversity. Methods Field and roadside surveys were carried out to record the presence of the species. [...]
Highlights
The development of international trade and the increased exchange of foods around the world have contributed to the dispersal of many plant species outside their native areas (Hulme, 2009)
This research work aimed at mapping the actual extent of occurrence of C. odorata across phytogeographical areas in Benin to give insight of the importance of the invasion and the threat it represents to agricultural system and biodiversity
Eight phytogeographical districts out of the ten were already infested by Siam weed. These results show an increasing in its geographical range compared to the results of Yehouenou (1993) who reported the occurrence zones only in guinean and sudano-guinean zones
Summary
The development of international trade and the increased exchange of foods around the world have contributed to the dispersal of many plant species outside their native areas (Hulme, 2009). Many of them have established themselves in these new environments, taking advantage of more or less favorable ecological conditions and/or using their bioecological potential for adaptation and causing ecological and economic damages (Russell, Blackburn, 2017). These species are referred to as invasive alien species based on the above mentioned considerations (International Union for Conservation of Nature, 2000). Invasive weeds pose a serious threat to agricultural systems worldwide and the management of such species requires information on their distribution. Abundance data were submitted to analysis of variance to compare infestation level across biogeographical zones, and correlation of the species distribution with environmental factors was examined
