Population dynamics modelling thrips
Web1) Population density plays an important role in the ini-tial phase of thrips population growth (N OTHNAGL et al. 2007). 2) Food supply will be important for thrips population growth. … 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 …

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 ...

They are sometimes known as patch models , but there does not seem to be a common established terminology. All of these modeling approaches (Table 1.1 ) are originally deterministic but have been extended to include stochastic elements.
