Future rainfall variations reduce abundances of aboveground arthropods in model agroecosystems with different soil types

Climate change scenarios for Central Europe predict less frequent but heavier rainfalls and longer drought periods during the growing season. This is expected to alter arthropods in agroecosystems that are important as biocontrol agents, herbivores or food for predators (e.g. farmland birds). In a lysimeter facility (totally 18 3-m2-plots), we experimentally tested the effects of long-term past vs. prognosticated future rainfall variations (15%...
