Population extinction and growth on a fluctuating fitness seascape

Summary

I.     Introduction to population growth: Logistic curve and generalizations, migration and stochasticity (demographic and seascape)

II.    Mean field approach: self-consistent steady state distributions

III.   Neutral fitness landscape: broad power-law distributions from stochasticity

IV.    Extinction on a seascape: New universality class and its limits

With seascape stochasticity                             

With demographic fluctuations included:         

V.    Growth/decay on a seascape: Richard's equation
