ABSTRACT OPP-9214970 SEDINGER This project seeks to develop a dynamic model to describe the potential impact of climate variation on the tropic structure of a coastal Alaskan ecosystem by assessing the degree to which climate change influences habitat structure and availability with the population dynamics of a colonially nesting bird, the Pacific brant. The area of study, the Yukon-Kuskokwim Delta, has been traditionally exploited by Yup'ik people and geese are a seasonally important resource. A parallel study of native oral history will be conducted in order to access traditional knowledge of the ecology of this region.

本项目旨在建立一个动态模型，通过评估气候变化对栖息地结构和可用性的影响程度，通过种群动态来描述气候变化对阿拉斯加沿海生态系统热带结构的潜在影响。研究的区域是育空-库斯库温三角洲，传统上是雅卜克人开发的，鹅是一种重要的季节性资源。为了获取该地区生态的传统知识，将对当地口述历史进行平行研究。
