| Research Abstract |
Ants, termites, clonal plants and corals are key taxa for conservation of biodiversity and ecosystem services. They share the characteristic, i. e. superorganisms of spatially fixed life. We tried to integrate sociobiology and community ecology of those taxa by focusing on how those organisms are adapted to environmental disturbances. Such an approach is important both in purely scientifically and applied perspectives(such as controlling biological invasion). We noticed a trade off between offspring size and migration distance(trade off related to the resource partitioning). We theoretically predicted the adaptive life history patterns under various disturbance regimes. To generalize the idea we used a matrix model of life history evolution in addition to spatially explicit simulation models. We also focused on different types of competition(interference or exploitative). We have obtained some seemingly general predictions that are going to be tested in ants, termites, plants and corals. Two international symposia were held in Japan related to this topic.
