Evaluation of establishment and expansion of exotic weed species
Overview of the research
International trade is a major route by which non-indigenous organisms are introduced into new habitats. Various kinds of weed seeds have been introduced through grain trade. The objectives of my study are to understand establishment and expansion of plants introduced by the grain trade in Japan.
