Seed predation may remove over 90% of the dispersed seed and is a part of natural weed control. Ground beetles (Coleoptera: Carabidae) are important seed predators but their role of a %22living herbicide%22 is limited by the fluctuation in abundance. Increasing their efficiency needs to make the field environment more friendly. Therefore their requirements for habitats should be studied. Diversity of carabids increases with abundance of weeds, but the effect of particular composition of weed assemblage on community structure of granivorous carabid beetles is not known. This will be studied in the research project. Because different carabid species have preference for particular seed species, the diversification in carabid fauna between weed patches is expected. Establishing these relationships may be used in creating environment, which will promote population density of granivorous carabids and reduce the assemblages of weeds to density"@en . .
