In evolutionary dynamics, the notion of a “well-mixed” population is usually associated with all-to-all interactions at all times. This assumption simplifies the mathematics of evolutionary processes, and makes analytical solutions possible. At the same time the term “well-mixed” suggests that this situation can be achieved by physically stirring the population. Using simulations of...

Cannibalism is a conspecific lethal interaction, a typical phenomenon in many natural populations, which is used as a ``life-boat strategy" to avoid circumstances leading to extinction. It is observed in many experimental studies that the cannibalistic nature of natural enemies deters the outcome of biological pest control programs. One of the ways to deviate natural enemies from conspecific...
