Do incremental increases of the herbicide glyphosphate have indirect consequences for spider communities?

Abstract

We examined the indirect effect of the herbicide glyphosate on field margin spider communities.We found that species turnover and cluster variation did not differ significantly between treatments. We attribute the lack of any effect to a large number of common agricultural species which are never eliminated from a habitat, but are instead significantly reduced. This within-season species turnover is related to the decline in vegetation height and the increase in percentage dead vegetation cover in the field margin
