项目摘要
While nature often changes slowly, sometimes large changes occur fast. Fisheries collapse, rangelands decline, and invasive species expand rapidly often with high costs to human society. Big changes in ecological systems are difficult to forecast, but recent theoretical studies and experiments indicate that they are preceded by early warnings. These early warnings are like economic indicators and can be detected in environmental variables that can be measured frequently. In principle when early warning indicators are detected, actions can either avert unwanted changes, like responding to a check engine light in a car, or help minimize risk, like responding to a tornado siren. This project will test the potential to avoid unwanted changes in lakes by detecting early warning signals. Several lakes will be experimentally fertilized with nutrients to create the potential for massive growths of algae. Early warning signals will be detected by continuously monitoring the lakes with modern electronic sensors. In a further experiment, the researchers will respond to signals that indicate impending changes and stop the nutrient additions to one lake in an attempt to avoid algae proliferating to nuisance levels. Treatments to the other lakes will continue so that all possible responses are included.This project will determine if methods for detecting early warnings signals can be developed. The findings from this study will be extended to a network of researchers who have established continuous measurement systems on lakes throughout the world. If successful, the results should be widely applicable for the management of a range of natural systems, not only lakes. The project will train graduate and undergraduate students and contribute to teaching materials for courses at universities in Virginia and Wisconsin, as well as advanced special topics courses at the Cary Institute of Ecosystem Studies in New York.
虽然自然界的变化往往是缓慢的,但有时大的变化发生得很快。 渔业崩溃,牧场减少,入侵物种迅速扩张,往往给人类社会带来高昂的代价。 生态系统的重大变化很难预测,但最近的理论研究和实验表明,这些变化之前有预警。 这些早期预警就像经济指标,可以在可以经常测量的环境变量中检测到。 原则上,当检测到早期预警指标时,行动可以避免不必要的变化,例如对汽车中的检查引擎灯做出反应,或者帮助降低风险,例如对龙卷风警报器做出反应。 该项目将测试通过检测早期预警信号来避免湖泊发生不必要变化的潜力。 几个湖泊将实验性地用营养物施肥,以创造藻类大量生长的潜力。 预警信号将通过现代电子传感器持续监测湖泊来检测。 在进一步的实验中,研究人员将对指示即将发生的变化的信号做出反应,并停止向一个湖泊添加营养物质,以避免藻类增殖到令人讨厌的水平。对其他湖泊的处理将继续进行,以便包括所有可能的反应。该项目将确定是否可以开发检测早期预警信号的方法。这项研究的结果将扩展到一个研究人员网络,这些研究人员在世界各地的湖泊上建立了连续测量系统。如果成功的话,其结果将广泛适用于一系列自然系统的管理,而不仅仅是湖泊。 该项目将培训研究生和本科生,并为弗吉尼亚州和威斯康星州的大学课程以及纽约的卡里生态系统研究所的高级专题课程提供教材。
