Life on the Move: Modeling the Effects of Climate-Driven Range Shifts with Integrodifference Equations

摘要: Climate change is causing many species to shift their ranges. We analyze an integrodifference equation that combines growth, dispersal, and a shifting habitat in order assess the impact of climate on persistence. apply this model butterflies show over-dispersal under-dispersal can both lead extinction. focus critical range-shift speed (for extinction), survey numerical methods for determining speed, introduce new analytic approximations speed. Finally, we our variety redistribution kernels critical-speed curves shed light complicated effects dispersal persistence changing climatic environment.
