Aggregation and stability in parasite-host models






Parasitology 104: 199-205

Aggregation and stability in parasite-host models

The 2-dimensional approximation of models of macroparasites on homogeneous populations developed by Anderson & May (1978) is generalised, focusing on how the dispersion (the variance to mean ratio) of the equilibrium distribution of parasites on hosts is related to the stability of the equilibrium. In the approximate system it was shown that the equilibrium is stabilized not by aggregation, but by dispersion which increases as a function of the mean.
