Spatio-temporal dynamics of weed seed eating carabid species in agricultural mosaics: variation of annual habitat quality of oil seed rape and role o…

2017

National audience; Carabid beetles are considered as important contributors to the regulation of weeds and recent studies have shown that weed seed predation by carabids may partly substitute for herbicide use in agriculture. Enhancing this ecosystem service requires to understand the spatio-temporal distribution of these species during the cropping season. Infra-annual variation in the spatial distribution of ground beetles within agricultural mosaics is less documented but of prime importance given that agricultural landscapes are highly dynamics. Indeed, crop phenology, agricultural operations but also habitat requirements during life cycle can lead to a redistribution of individuals bet…
