项目摘要

The central goal of community ecology is to explain the substantial degree to which natural communities vary in composition. Plant communities, for example, vary in the number of species they host, how community resources are divided among resident species, and in the morphology of constituent species. While considerable effort has gone into understanding the mechanisms that drive this variation, many questions are still unresolved, and many competing theories are still vigorously debated. For example, it is clear that competition plays an important role in plant communities; however, current models of competition suggest that competition will result in the exclusion of all but the most competitive species. Given that virtually all natural communities contain more than one species, it stands to reason that either the impact of competition is mitigated by other processes that promote diversity, such as dispersal, or that the competitive process is more complicated than we know, and tends not to result in the loss of all but the most competitive species. My students and I will examine these possibilities by developing more realistic models of multi-species competition, testing these models with manipulative field experiments, and by using null modeling techniques to identify and quantify the impacts of competition, dispersal, and herbivory in natural communities spanning important environmental gradients. This work will contribute to the growing body of literature concerning how these important mechanisms interact to shape natural communities. Additionally, understanding the relative impact of different mechanisms that may augment (e.g., dispersal), or reduce diversity (e.g., competition) will greatly inform conservation and restoration initiatives, and aid in the management of invasive species.
群落生态学的中心目标是解释自然群落在组成上的差异程度。 例如,植物群落在其宿主物种的数量、群落资源在常驻物种之间的分配方式以及组成物种的形态方面各不相同。 虽然已经付出了相当大的努力来理解驱动这种变化的机制,但许多问题仍然没有解决,许多相互竞争的理论仍然存在激烈的争论。 例如,很明显,竞争在植物群落中起着重要的作用;然而,目前的竞争模型表明,竞争将导致除最具竞争力的物种外的所有物种被排除在外。 考虑到几乎所有的自然群落都包含不止一个物种,因此,要么竞争的影响被其他促进多样性的过程(如扩散)所减轻,要么竞争过程比我们所知的要复杂得多,而且往往不会导致所有物种的丧失,但最具竞争力的物种除外。 我和我的学生将通过开发更现实的多物种竞争模型来研究这些可能性,用操纵性实地实验来测试这些模型,并通过使用零模型技术来识别和量化竞争,扩散和草食动物在跨越重要环境梯度的自然群落中的影响。 这项工作将有助于越来越多的文献,这些重要的机制如何相互作用,以塑造自然社区。 此外,了解可能增加的不同机制的相对影响(例如,分散),或减少多样性(例如,竞争)将极大地为保护和恢复举措提供信息,并有助于管理入侵物种。
