一般講演（ポスター発表） P1-292A (Poster presentation)
Habitat loss is one of main causes of recent mass extinction of biospecies. However, a cause-and-effect relation between the destruction of the habitat and extinction is very complicate. So far, the effect of local destruction has been studied by two different approaches: site destruction and bond destruction. In the former, species cannot live in the destructed site. In contrast, in the latter, the interaction between adjacent lattice sites is disturbed. In this paper, we present the bond destruction models consisted of multiple species. Interactions occur between adjacent lattice sites. Simulations reveal parity rules, where, the parity means the even or odd. The mean-field theory can predict a parity rule. However, the agreement between theory and simulation is not sufficient.
