Many of the traditional approaches in ecological theory are based on the paradigm that natural ecosystems return to stable states. Thus, traditional approaches to environmental problems draw on the large body of mathematical and statistical techniques for analyzing such systems. These approaches, however, have clear limitations. Just as ecologists emphasize that long-term experiments yield different results from short-term experiments, theory needs to take the role of time scales into account, and look beyond an emphasis on stability. In the context of this proposal, the PI's will develop the mathematical and statistical tools to understand the role of transient dynamics (as opposed to dynamics connected with stability) in ecological systems. This study will both aid our basic understanding of real ecological systems, and refine old and open up new approaches to environmental management. To cope with the often sudden and large impacts that humans can have on ecosystems, there is growing interest in management strategies that change as managers learn and as an ecosystem is beset by new shocks. Implementing adaptive management, however, requires a far more sophisticated understanding of how short-term, observed dynamics of a system generate long-term patterns that ultimately determine sustainability. Students will also receive important interdisciplinary training.

生态理论中的许多传统方法都是基于自然生态系统恢复到稳定状态的范式。因此，环境问题的传统方法借鉴了分析此类系统的大量数学和统计技术。但是，这些方法有明显的局限性。正如生态学家强调的是，长期实验从短期实验中产生不同的结果一样，理论需要考虑时间尺度的作用，并且超越了对稳定性的重视。在本提案的背景下，PI将开发数学和统计工具，以了解生态系统中短暂动力学的作用（与稳定性相关的动态）。 这项研究既将有助于我们对真实生态系统的基本理解，又可以完善旧的并开辟了新的环境管理方法。为了应对人类对生态系统产生的常常和大型影响，随着管理者的学习和生态系统的变化，人们对管理策略的兴趣越来越大，并被新的冲击所吸引。但是，实施自适应管理需要对系统的短期，观察到的系统产生最终决定可持续性的长期模式的动态更加复杂。学生还将接受重要的跨学科培训。
