A crucial question in ecology is the ?characteristic? scale or scales at which a system should be observed to most clearly observe its deterministic dynamics. We propose to modify methods recently developed for model ecosystems so they may be applied to real ecosystems, assess the performance of these measures in identifying unambiguous length scales, and ascertain what these scales reveal about the underlying ecology. The work will provide significant advances to important applied scaling questions such as the optimal size of reserves and ecosystem management ?units?, and the appropriate scale of observation to detect deterministic trends in ecosystem dynamics.

生态学中的一个关键问题是？特征？一个或多个观察系统以最清楚地观察其确定性动态的尺度。我们建议修改最近为模型生态系统开发的方法，以便它们可以应用于真实生态系统，评估这些措施在确定明确的长度尺度方面的表现，并确定这些尺度揭示了潜在的生态。这项工作将在重要的应用尺度问题上取得重大进展，如保护区和生态系统管理单位的最佳规模，以及检测生态系统动态确定性趋势的适当观测规模。
