Assessing how uncertainty and stochasticity affect the dispersal of fish in river networks

Abstract

•We simulated the spread of fish in river networks of varying habitat heterogeneity.•We studied parameter uncertainties and stochasticity inherent to dispersal.•Fish spread was more sensitive to dispersal and less to demographic parameters.•Stochastic effects cause considerable unpredictability of the dispersal distance.
