项目摘要

PROJECT ASTRACTThis project seeks to discover the general rules that govern how natural ecological communities are put together. Discovery of these rules will have immense practical value in predicting the causes and consequences of biological invasions, evaluating the influence of biodiversity in ecosystem functions, directing the restoration of degraded ecosystems, and guiding the development of public environmental policy. We have selected ant communities for study because they have long served as a model system for studying ecological processes that control patterns of species richness, species composition and relative abundance of species. The primary goal of this project is to develop and test an integrative, mechanistic theory of species interactions in local ant communities. This theory focuses on a set of interspecific trade-offs as a general mechanism that controls species richness, composition and abundance in ant communities. The project will be the first attempt to develop a comprehensive theory of species interactions in ant communities that integrates the effects of both competition for shared resources and attack by natural enemies. The approach of identifying generalized trade-offs associated with competitive ability and defense against natural enemies should have broad applicability and lead to efficient and rapid progress toward a general understanding of ecological communities. In addition to the proposed research, the major educational goal of this project is to begin training a new generation of community ecologists who are equally adept at theoretical modeling and empirical analysis.
项目摘要该项目旨在发现管理自然生态群落如何组合在一起的一般规则。这些规律的发现对于预测生物入侵的原因和后果、评估生物多样性对生态系统功能的影响、指导退化生态系统的恢复、指导公共环境政策的制定都具有巨大的实用价值。我们选择蚂蚁群落进行研究,因为它们长期以来一直作为研究控制物种丰富度、物种组成和物种相对丰度模式的生态过程的模型系统。该项目的主要目标是开发和测试当地蚂蚁群落物种相互作用的综合机械理论。该理论重点关注一组种间权衡,作为控制蚂蚁群落物种丰富度、组成和丰度的一般机制。该项目将是开发蚂蚁群落物种相互作用综合理论的首次尝试,该理论综合了共享资源竞争和天敌攻击的影响。确定与竞争能力和防御天敌相关的广义权衡的方法应该具有广泛的适用性,并有助于有效和快速地取得对生态群落的普遍理解。除了拟议的研究之外,该项目的主要教育目标是开始培训同样擅长理论建模和实证分析的新一代社区生态学家。
