Population dynamics modelling thrips
Webmodels of population dynamics were built with pre-defined models, such as ONEPOP (Gross et al. 1973) and later POP-II (Bartholow 1992). I describe these models as black box models, because as both a model developer and a model user, you are not quite sure what is in the model. You can not peer into the black box of a model to see the inner ... WebModel-derived calculations of thrips population growth rate enable the estimation of the minimum predator density at which thrips benefit from using the web as a refuge. The model also predicted a minor effect of the refuge on the prey density at equilibrium, indicating that the effect of refuges on population dynamics hinges on the temporal scale …
