Abstract00-83545CarpenterBiocomplexity: Divergent dynamics: Complex interactions of riparian land, people and lakesSurprises -large, unexpected changes from apparently small causes -are common in systems of people and nature. Are these surprises a consequence of the complexity or nonlinearity of natural-social systems? Or can they be explained by simpler processes? This research project addresses this question for systems composed of lakes, their riparian vegetation and land use, and social and economic organizations of lake users. The investigators will study the self-organization of lake users and associated characteristics of shoreline and lake ecosystems. The project will determine whether thresholds in riparian organization set the stage for an important class of surprises: collapses of economically important game fish stocks. The researchers will also test the possibility that nonlinear dynamics can be used to design manipulations that remove invading crayfish from a lake. If successful, this experiment will catalyze a self-sustaining removal of an invasive species - a path-breaking ecological restoration.

生物复杂性：发散动力学：河岸土地、人和湖泊的复杂相互作用惊奇--由表面上很小的原因引起的巨大的、意想不到的变化--在人与自然的系统中很常见。 这些意外是自然社会系统的复杂性或非线性的结果吗？ 或者可以用更简单的过程来解释？ 本研究项目针对由湖泊、其河岸植被和土地利用以及湖泊使用者的社会和经济组织组成的系统解决这一问题。 调查人员将研究湖泊使用者的自我组织以及海岸线和湖泊生态系统的相关特征。 该项目将确定河岸组织的阈值是否为一类重要的意外事件奠定了基础：经济上重要的游戏鱼类种群的崩溃。 研究人员还将测试非线性动力学可用于设计将入侵的小龙虾从湖中清除的操作的可能性。 如果成功的话，这个实验将催化一个自我维持的入侵物种的清除-一个开创性的生态恢复。
