Do the heterogeneity and composition of agricultural landscapes in Central Chileinfluence native and exotic coccinellids in alfalfa fields?


Abstract: We evaluated the effect of the compositional and configurational heterogeneity oflandscapes and of the most common cover types surrounding alfalfa fields on the abundance anddiversity of native and exotic coccinellids in alfalfa. Coccinellid assemblages in alfalfa did notrelate with compositional and cofigurational heterogeneity, but they were affected by theabundance of different cover types, with abandoned fields being the only cover type thatdifferentially affected native and exotic species.
