ARTHROPODS PROVIDE ESSENTIAL ECOSYSTEM SERVICES SUCH AS POLLINATION AND BIOLOGICAL CONTROL THAT ARE CRUCIAL TO MAINTAIN PRODUCTIVITY WORLDWIDE. AGRICULTURAL INTENSIFICATION, WHICH HAS CAUSED HABITAT AND SPECIES LOSS AT LARGE SCALES, HAS BEEN IDENTIFIED AS ONE DRIVER LEADING TO THE LOSS OF ECOSYSTEM SERVICES. NOT JUST SPECIES COMPOSITION, BUT MORE IMPORTANTLY, FUNCTIONAL TRAITS SUCH AS BODY SIZE AND HOST PREFERENCE HAVE BEEN SHOWN TO DETERMINE THE SERVICES PROVIDED BY ARTHROPOD COMMUNITIES TO AGRO-ECOSYSTEMS. CURRENT EVIDENCE SUGGESTS THAT LANDSCAPE SIMPLIFICATION CAN FILTER AND HOMOGENIZE COMMUNITY FUNCTIONAL TRAITS. UNTIL NOW RESEARCH HAS FOCUSED ON UNDERSTANDING FUNCTIONAL TRAIT VARIATION CAUSED BY SPECIES TURNOVER COMPLETELY NEGLECTING INTRASPECIFIC VARIATION. ALSO UNKNOWN REMAINS IF THE MEASURED CHANGES IN FUNCTIONAL TRAITS ACTUALLY AFFECT ECOSYSTEM SERVICES. HERE WE WANT TO DISENTANGLE THE EFFECT OF SPECIES TURNOVER AND INTRASPECIFIC VARIATION ON FUNCTIONAL TRAITS IN POLLINATOR,HERBIVORE AND NATURAL ENEMY COMMUNITIES. WE ALSO WANT TO TEST IN THE FIELD AND EXPERIMENTALLY WHAT THE CONSEQUENCES OF LANDSCAPE-MEDIATED CHANGES IN FUNCTIONAL TRAITS ARE ON ECOSYSTEM SERVICES SUCH AS CROP PRODUCTIVITY. OUR GOALS DIRECTLY ADDRESS THE PROGRAM AREA PRIORITY, INTERACTIONS OF PESTS AND BENEFICIAL SPECIES WITH ENVIRONMENTAL STRESSORS. BY STUDYING THE EFFECTS OF LANDSCAPE SIMPLIFICATION ON HERBIVORE, POLLINATOR AND NATURAL ENEMIES FUNCTIONAL TRAITS WE WILL BE ABLE TO DISENTANGLE THE EFFECTS OF INTRASPECIFIC AND INTERSPECIFIC VARIATION OF FUNCTIONAL TRAITS ON ECOSYSTEM SERVICES. OUR RESULTS WILL ALLOW US TO RECOMMEND TARGETED MANAGEMENT PRACTICES AIMED AT PRESERVING NOT ONLY SPECIES, BUT FUNCTIONAL TRAITS THAT MIGHT BE MORE IMPORTANT FOR THE SUSTAINABLE LONG-TERM MAINTENANCE OF ECOSYSTEM SERVICES.
