The international symposium on alternative stable states will take place at Kyoto University Seminar House in Kyoto, 28th July 2016.
The aim of the symposium is to review the recent advances in research areas of alternative stable states, catastrophic regime shift and historical contingency in community assembly, with particular emphasis on exploring the interface between community ecology, ecosystem ecology and evolution. While the conference is mainly aimed at theoretical biologists, there will be a strong experimental component, with discussion of new results and future experiments.
The format of this symposium follows a keynote review and several oral presentations. The topics that will be covered include: bifurcation theory, critical slowing down, early warning signal, eco-evolutionary feedbacks, ecosystem management, environmental DNA (metagenomics), experimental evolution, nonlinear dynamics forecasting (CCM), invasion ecology, food web dynamics, material cycling, predictive ecology, resilience and restoration.
28th July 2016 (Thursday) 9:30am- (registration opens at 9am)
Seminar House (Graduate School of Science), Kyoto University (Link to the KU campus map (find here Bldg No.10 [A10]))
Keynote Lecture Abstract: Some ecological communities can be found in different states under the same environmental conditions. Whether such community is in either of these possible alternative states at a given location and time depends on the history of the system. The existence of alternative stable states has important consequences for ecosystem management, conservation and restoration. In particular, such community can abruptly shift from one stable state to another following a perturbation, what has been referred to as catastrophic shifts, sometimes with important ecological and economic consequences. This leads to a broad range of research aiming at identifying the conditions that favor the emergence of alternative stable states in ecological communities, and at devising indicators of upcoming catastrophic shifts. In this presentation, I will give a brief overview of the history of the concept of alternative stable states through ecological theory, I will highlight the gaps between theory and empirical studies and present some future research prospects
