The ecology of extinction

摘要: Studies of species-area curves and the spatial correlation biogeographic ranges with climatic variables may allow some crude prediction amount extinction over large regions in face major environmental change. However, these approaches tell little about proximate causes species loss. The contention that failure metapopulation dynamics is at root many extinctions so far not borne out by observed rates inter-population movement. Rather, most have a structure seem to central source populations peripheral sink populations. Much recorded ecological literature probably such their loss has do extinctions. disappearance central, more important but its are well documented. Habitat single greatest ultimate cause current extinction. very last individuals population be obviously related habitat it mysterious, because will look healthy, or attributable one stochastic forces widely assumed set minimum viable sizes.
