一般講演（ポスター発表） P2-229 (Poster presentation)
Mound-building termites function as ecological engineers in savanna ecosystem. It is known that large termite mounds support a greater diversity of plants than the matrix. The process of the distinct vegetation on the mounds, however, is not understood enough. The objective of this study was to describe the characteristics of the vegetation and discuss the process of the vegetation in north-western Namibia. Firstly I compared; (1) the structure, the species composition and the traits of the vegetation on the mounds to the matrix. Then, to know the potential dispersers, I observed (2) frugivores feed on the pioneer species on termite mounds.
Diverse woody plant assemblages were found on termite mounds. The mounds had more evergreen and animal dispersal trees, while the matrix had more deciduous and wind dispersal trees. Salvadora perica was the most frequent species and appeared on a half of the active mounds, followed Capparis tomentosa. These two fleshy fruit trees were fed by several kinds of avian species. In conclusion, termite mounds had the diverse woody plant assemblages, and it was suggested that the animal seed dispersal possibly contribute the formation of the vegetation on termite mounds.
