Sammanfattning

Question: Under what circumstances does a capacity for multi-stage dormancy (i.e. dormancy

in more than one life-stage) evolve?

Mathematical methods: Optimization in stochastic environments. Results are derived both

analytically and by simulations.

Key assumption: There exists some trade-off between resources allocated to reproduction and

adult dormant survival. Different shapes of this trade-off are investigated.

Major conclusions: Multi-stage dormancy can evolve in an environment with low serial

autocorrelation. However, a slowly changing environment, with high positive autocorrelation,

will prevent the evolution of dormancy in several life-stages. In general, a high positive

environmental autocorrelation will separate the evolution of life parameters associated with

active life from that of parameters associated with dormant life.
