“…2d). Edge in the landscape could effectively increase the migration of species into or out of a habitat and could be used as a simple corridor for several species of insects (Jauker, Diekötter, Schwarzbach, & Wolters, 2009). This is similar to the research result by Holzschuh, Steffan-Dewenter, & Tscharntke (2010) that showed bees were enhanced by high edge density of noncrop habitat.…”

“…For example, hoverflies are likely to be still present in real landscapes after declines in bee diversity (Jauker et al 2009) and might buffer pollination. In our experiment, hoverflies contributed only little to pollination, despite similar number of flower visits and higher number of individuals compared to bees.…”

Abstract. Biodiversity is important for many ecosystem processes. Global declines in pollinator diversity and abundance have been recognized, raising concerns about a pollination crisis of crops and wild plants. However, experimental evidence for effects of pollinator species diversity on plant reproduction is extremely scarce. We established communities with 1-5 bee species to test how seed production of a plant community is determined by bee diversity. Higher bee diversity resulted in higher seed production, but the strongest difference was observed for one compared to more than one bee species. Functional complementarity among bee species had a far higher explanatory power than bee diversity, suggesting that additional bee species only benefit pollination when they increase coverage of functional niches. In our experiment, complementarity was driven by differences in flower and temperature preferences. Interspecific interactions among bee species contributed to realized functional complementarity, as bees reduced interspecific overlap by shifting to alternative flowers in the presence of other species. This increased the number of plant species visited by a bee community and demonstrates a new mechanism for a biodiversity-function relationship (''interactive complementarity''). In conclusion, our results highlight both the importance of bee functional diversity for the reproduction of plant communities and the need to identify complementarity traits for accurately predicting pollination services by different bee communities.

“…Such context dependency has also been shown for biological control, which is predicted to be higher in more complex landscapes (Bianchi et al, 2006). Hence, to account for complex interactions with complementary habitat types or non-linear relationships to habitat area (Jauker et al, 2009, see also Hauck et al, 2013), a simple mapping from the extent of different habitat types may not suffice, but instead a spatially explicit landscape perspective on ecosystem services is needed.…”

† These authors have contributed equally to this work.The concept of ecosystem services was originally developed to illustrate the benefits that natural ecosystems generate for society and to raise awareness for biodiversity and ecosystem conservation. In this article we identify major challenges and opportunities for ecologists involved in empirical or modeling ecosystem service research. The first challenge arises from the fact that the ecosystem service concept has not been generated in the context of managed systems. Ecologists need to identify the effect of anthropogenic interventions in order to propose practices to benefit service-providing organisms and associated services. The second challenge arises from the need to evaluate relationships between indicators of ecosystem services that are collected in ecological studies while accounting for uncertainties of ecological processes that underlie these services. We suggest basing the assessment of ecosystem services on the utilization of sets of indicators that cover aspects of service-providing units, ecosystem management and landscape modification. The third challenge arises from the limited understanding of the nature of relationships between services and a lack of a general statistical framework to address these links. To manage ecosystem service provisioning, ecologists need to establish whether services respond to a shared driver or if services are directly linked to each other. Finally, studies relating biodiversity to ecosystem services often focus on services at small spatial or short temporal scales, but research on the protection of services is often directed toward services providing benefits at large spatial scales. Ecological research needs to address a range of spatial and temporal scales to provide a multifaceted understanding of how nature promotes human well-being. Addressing these challenges in the future offers a unique opportunity for ecologists to act as promoters for the understanding about how to conserve benefits gained from nature.
