First meeting: 07.-11.11.2016
Ecology has a tradition of using predictions to test hypotheses and theories, however, anticipating how global environmental change will affect natural ecosystems requires a new set of tools and thinking to help safeguard biodiversity for future generations. Currently, quantitative statements of how well community ecology does in prediction are hampered by a lack of quantitative data. However, even with the few syntheses that are available, it is hard to judge whether predictive skill (i.e. realized predictability) in ecology is good or bad, because we do not know how much predictive structure (i.e. intrinsic predictability) ecological data contains and hence how difficult it is to make ecological predictions. We aim to develop a theory of intrinsic predictability and thus provide ecologists with a tool to address when and why their forecasting strategies succeed or fail. We will synthesize methods developed in fields such as computer science and complex systems to infer intrinsic predictability on simulated ecological datasets and then apply these metrics to empirical datasets from Lake Constance and experimental mesocosms. By issuing a data request to practitioners, we will collect datasets with existing realized predictions, with which we can apply the metrics of intrinsic predictability broadly across ecosystem types. With this analysis, we aim to establish the baseline of intrinsic and realized predictability in community ecology, and start a dialogue about the data needed for improving predictive models. Our workshop is timely, because we not only critically need to quantify, but anticipate the effects of global change on global biodiversity to implement successful conservation and management.
