标题： Coupling the socio-economic and ecological dynamics of cyanobacteria: single lake and network dynamics

摘要： 在近几十年中，淡水湖泊中人类活动有所增加。 这种人类活动的常见副产品是富营养化，这很容易导致有害的蓝藻水华。 在这项工作中，我们提出了一种模型，该模型耦合了与蓝藻系统相关的社会经济和生态动态。 社会经济动态考虑了人类群体关于是否减少污染水平的选择。 这些选择基于各种与社会排斥、社会规范、环境关注和经济负担有关的成本。 耦合模型表现出双稳态动力学，其中一个稳定状态对应于高强度缓解措施和低蓝藻含量，另一个对应于低强度缓解措施和高蓝藻含量。 此外，我们考虑湖泊网络中的社会互动，并提出了与各种相关成本和社会情况有关的动态结果。 在每种情况下，我们都展示了合作程度和蓝藻含量之间潜在的制度转变。 社会排斥和压力被证明是导致此类制度转变的驱动因素。 显示英文摘要

摘要： In recent decades freshwater lakes have seen an increase in human presence. A common byproduct of this human presence is eutrophication, which readily results in harmful cyanobacteria blooms. In this work we propose a model that couples the socio-economic and ecological dynamics related to cyanobacteria systems. The socio-economic dynamics considers the choices a human population makes regarding whether or not to mitigate their pollution levels. These choices are based on various costs related to social ostracism, social norms, environmental concern and financial burden. The coupled model exhibits bistable dynamics, with one stable state corresponding to high mitigation efforts and low CB abundance, and the other to low mitigation efforts and high CB abundance. Furthermore, we consider social interactions among a network of lakes and present dynamic outcomes pertaining to various associated costs and social situations. In each case we show the potential for regime shifts between levels of cooperation and CB abundance. Social ostracism and pressure are shown to be driving factors in causing such regime shifts.
