    Description: Recent events and trends in international relations are making it necessary for scientists to design their projects in ways that can integrate disciplinary perspectives and learn how to communicate their results in governance processes. Some examples of settings in which such skills would be needed are the debates about the political and legal relevance of the “Anthropocene” as a concept, the establishment and implementation of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the recent International Court of Justice’s decision on what constitutes “scientific purpose” under the Whaling Convention, and the ongoing international efforts to regulate deep seabed mining activities. These events reveal an acceleration of growing environmental, distributional, and geostrategic conflicts over ocean resources which are changing the character of marine research. For some time now marine sciences have recognized the interdependence of social and ecological systems and the cumulative effects of multiple environmental pressures. In addition, we observe that the relationship between science and policymaking is rapidly changing in a process which we refer to here as the internationalization of knowledge, and that scientific research activities and results are progressively being internationally contested. Altogether these developments constitute extrinsic constraints that render transcending disciplinary boundaries a conditio sine qua non for future marine research. Better comprehension of these trends and their implications may help us to understand marine science’s functioning in the near future, particularly the relationship between disciplines involved.

    Description: There is still considerable debate about which mechanisms drive the relationship between biodiversity and ecosystem function (BEF). Although most scientists agree on the existence of two underlying mechanisms, complementarity and selection, experimental studies keep producing contrasting results on the relative contributions of the two effects. We present a spatially explicit resource competition model and investigate how the strength of these effects is influenced by trait and environmental variability, resource distribution, and species pool size. Our results demonstrate that the increase of biomass production with increasing species numbers depends on the concurrence of environmental and trait variability: BEF relationships are stronger if functionally different species coexist in a landscape with heterogeneous resource supply. These large biodiversity effects arise from complementarity effects, whereas selection effects are maximized when broad trait ranges coincide with narrow ranges of resource supply ratios. Our results will therefore help to resolve the debate on complementarity and selection mechanisms.
