    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract The effects of different types foraging behaviour on the spatially explicit accumulation of contaminants are under consideration in this report. A conceptual model has been developed, which can be used to simulate the foraging behaviour of the little owl (Athene noctua) under different assumptions on the mode of foraging behaviour: random foraging, optimal foraging, central foraging, or a combination of optimal and central foraging. The result of the modelling exercises show that the different modes of foraging result in different accumulation rates, and associated risks. Hence, it is concluded that spatially explicit modelling of contaminant accumulation should be conducted with specific knowledge on the foraging behaviour of the organisms under study. Furthermore, it is shown in the current report that measures in habitat management may be used to alleviate risks that contaminants may pose to higher organisms.
