整个地球仪的社区越来越多地被赋予资源管理的责任，这使得有必要了解导致成功的基于社区的管理（CBM）的因素。在这里，我们评估了制度设计原则是否以及如何影响Arapaimasp.煤层气计划的生态结果，是亚马逊河流域重要的共有渔业资源。我们量化了奥斯特罗姆（科学325：419-422，1990年）的制度设计原则，在83个社区使用系统的调查，并定量连接的设计原则，以衡量生态结果（arapaima密度）在一个子集的39个社区，以评估其影响。为了了解建立信任措施机构能力的区域模式，我们评估了所有83个社区中每项原则的存在程度。在39个煤层气方案中，主要分数与arapaima密度呈正相关，解释了约一半的变化。与界定边界和分级制裁有关的设计原则对建立信任措施增加arapaima密度的能力产生了最大的影响。然而，大多数原则在所有83个社区中的存在程度普遍较低，其中两项最有影响力的原则（界定边界和分级制裁）的存在程度最低。虽然其他原则（管理规则，解决冲突，集体行动和监测系统）的作用可能是重要的，我们的研究结果表明，旨在加强存在的明确的边界和分级的制裁在社区举行的承诺，以提高arapaima区域建立信任措施的有效性的努力。
Communities throughout the globe are increasingly being given the responsibility of resource management, making it necessary to understand the factors that lead to success in community-based management (CBM). Here, we assessed whether and how institutional design principles affect the ecological outcomes of CBM schemes forArapaimasp., an important common-pool fishery resource of the Amazon Basin. We quantified the degree of presence of Ostrom’s (Science 325:419–422, 1990) institutional design principles in 83 communities using a systematic survey, and quantitatively linked the design principles to a measure of ecological outcome (arapaima density) in a subset of 39 communities to assess their influence. To understand regional patterns of institutional capacity for CBM, we evaluated the degree of presence of each principle in all 83 communities. The principle scores were positively related to arapaima density in the 39 CBM schemes, explaining about half of the variation. Design principles related to defined boundaries and graduated sanctions exerted the strongest influence on the capacity of CBM to increase arapaima density. The degree to which most principles were present in all 83 communities was generally low, however, with the two most influential principles (defined boundaries and graduated sanctions) being the least present of all. Although the roles of the other principles (management rules, conflict resolution, collective action, and monitoring systems) are probably important, our results indicate that efforts aimed at strengthening the presence of defined boundaries and graduated sanctions in communities hold promise to improve the effectiveness of arapaima CBM regionally.
