Effects of spatial heterogeneity on Jones's model for cyst-nematode population dynamics and crop root damage.
Abstract
Stochastic analogues that included variation in spatial heterogeneity of population densities and of parameter values in Globodera were produced using simple simulation, and results compared with those from Jones's deterministic models. When a field is sampled from several positions before a host crop is planted, and a range of initial nematode densities is obtained, then each of these sampled densities should be used as input to Jones's model to determine local populations or expected root damage.
