• discrete-time recursions
• integrodifference equations
• spreading speeds
• linear determinacy

A well-known formula for the spreading speed of a discrete-time recursion model is extended to a class of problems for which its validity was previously unknown. These include migration models with moderately fat tails or fat tails. Examples of such models are given.
