项目摘要

9400073 Wiens This award supports Professors John Wiens and Beatrice Van Horne, together with postdoctoral associate Thomas Crist, all of Colorado State University, to collaborate in ecological research with Nils Stenseth and his group in the Department of Biology of the University of Oslo, Norway. They are attempting to understand the relationship of the mosaic structure of landscapes to the ecology of individuals, and to translate these effects to the population and community levels. The Colorado State group has strengths in simulation modeling while the Oslo group emphasizes analytical, mathematical models. They will integrate these approaches to address common questions about how environmental heterogeneity affects ecological systems and about how these effects vary with spatial scale. Questions about the effects of scale and of explicit spatial heterogeneity on ecological systems have become a centerpiece of contemporary ecology. This collaboration will evaluate two methodological approaches to these questions by applying them jointly to independently gathered empirical data from the different systems being studied by the two groups. The result should be a contribution to predictive theory that will have significant applications in preserving biodiversity and threatened ecosystems. ***

9400073 Wiens这个奖项支持教授约翰·维恩斯（John Wiens）和比阿特丽斯·范·霍恩（Beatrice van Horne），以及科罗拉多州立大学全体科罗拉多州立大学的博士后助理托马斯·克里斯特（Thomas Crist），与NILS Stenseth及其小组合作，在挪威奥斯陆奥斯陆生物学系。他们试图了解景观的镶嵌结构与个人生态的关系，并将这些影响转化为人口和社区层面。科罗拉多州群体在模拟建模方面具有优势，而奥斯陆组则强调分析性的数学模型。他们将整合这些方法，以解决有关环境异质性如何影响生态系统以及这些影响如何随空间量表变化的常见问题。关于规模和显式空间异质性对生态系统的影响的问题已成为当代生态学的核心。该协作将通过将它们共同应用于两组研究的不同系统中独立收集经验数据来评估这些问题的两种方法学方法。结果应该是对预测理论的贡献，该理论将在保护生物多样性和威胁生态系统方面具有重要的应用。 ***
