The issues of biodiversity is central to biological sciences. The Amakusa Biological Laboratory is devoted to the study of ecological communities on local, regional and global scales. Building on the Laboratory's long-established strength in shallow water marine ecological research in Japan, we are now dealing with not only marine but also freshwater and terrestrial systems, as there is much to be gained from comparative approaches of community ecology.
As a major centre of research in aquatic ecology in Japan, the AMBL aims at elucidating how a multitude of species can coexist and maintain ecological assemblages under different environmental conditions and evolutionary backgrounds. Many important ideas and concepts in this field are summarised in "Species Coexistence".
