Optimal time allocation in parasitic wasps searching for hosts and food
Article Abstract:
Optimal time allocation decisions in parasitic wasps searching for hosts and food are predicted by using a stochastic dynamic programming model. The model predicts that parasitoids should always search for food if energy reserves drop to low levels, even if the probability of finding food and the average food reward are small.

Evolving dispersal and age at death
Article Abstract:
Key theories on ageing and programmed death are described and interplay between dispersal and age of death is studied. Results show that each trait can evolve in response to other. Earlier age of death evolves when individuals disperse less and greater dispersal distance evolves when individuals are programmed to die later.
