Modeling spatiotemporal dynamics of outbreaking species: influence of environment and migration in a locust.

abstract：:Rare species play limited ecological roles, but particular behavioral traits may predispose species to become functionally extinct before becoming rare. Flying foxes (Pteropodid fruit bats) are important dispersers of large seeds, but their effectiveness is hypothesized to depend on high population density that induce...
