Biocomplexity: Divergent Dynamics: Complex Interactions of Riparian Land, People and Lakes

[摘要]生物复杂性：分歧动力学：河岸土地、人与湖泊的复杂相互作用“意外”——由看似微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？或者它们可以用更简单的过程来解释？本研究项目为由湖泊、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了这个问题。调查人员将研究湖泊使用者的自组织以及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：经济上重要的狩猎鱼类种群的崩溃。研究人员还将测试非线性动力学可以用于设计从湖中移除入侵小龙虾的操作的可能性。如果成功，这个实验将催化入侵物种自我维持的移除——一个开创性的生态恢复。

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.
