Which species will succesfully track climate change? The influence of intraspecific competition and density dependent dispersal on range shifting dynamics

摘要: Understanding the ability of species to shift their geographic range is considerable importance given current period rapid climate change. Furthermore, a greater understanding spatial population dynamics underlying shifting required complement advances made in niche modelling. A simulation model developed which incorporates three key features that have been largely overlooked studies dynamics: form intraspecific competition, density dependent dispersal and transient habitat patches. The results show exact shape response depends critically on both local patch dynamics. Species whose competition contest based are more vulnerable than those scramble based. Contesters especially sensitive when combined with dispersal. living patches carrying capacity grows slowly also susceptible shifts environmental conditions. complementary analytic approach further highlights competition.
