Metapopulation model for Assessing Spatial and Temporal Effects of Pesticides (Effect)
MASTEP is a metapopulation model describing the decline and subsequent recovery of invertebrate populations after a periodic exposure to pesticides. It is able to evaluate the effects on and recovery of the species, using concentrations in surface water calculated for realistic worst case scenarios.
