"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 ... " - Population dynamics modelling thrips
