Type 'A' and 'B' recovery revisited: The role of field-edge habitats for Collembola and macroarthropod community recovery after insecticide treatment

摘要: Previous work has identified two patterns of arthropod recovery after insecticide applications to arable crops: dispersal-mediated recolonisation from untreated areas (Type A) and within treated assisted by reduced predation B). In this study, connectivity between field-edge habitats was manipulated using barriers investigate whether a crop edge adjacent hedgerow influence an insecticide-treated surface-active Collembola other arthropods. differed among closely-related taxa. Epigeic collembolan macroarthropod communities were more diverse abundant, rates artificial prey higher, in sprayed connected both unsprayed than the alone. These findings indicate that effectiveness edges as sources field may depend on adjoining margin habitats. An assumption risk assessment assist population is not supported.
