講座簡(jiǎn)介:
We discuss population models in forms of reaction-diffusion equations and integro-difference equations, which describe species growth and dispersal in a dynamic habitat. We show the results regarding persistence, spreading speeds, and traveling waves for a species in an expanding or contracting habitat and for a species intereacting with a competitor. The mathematical analysis involves linear determinacy, lower and upper solutions on moving intervals.
