0501012BlakeThis dissertation enhancement proposal supports Dr. John G. Blake and Ms. Cintia Cornelius, University of Missouri-Saint Louis, to work with Dr. Pablo A. Marquet at the Universidad Catolica de Chile in Santiago, Chile on the genetic and demographic consequences of human-driven landscape changes on birds. The goal of their project is to evaluate the relative importance of habitat deterioration and habitat fragmentation in limiting forest bird populations in a fragmented landscape in southern South American temperate rainforests. The two bird species they will use as model systems, Aphrastura spinicauda (Furnariidae) and Scelorchilus rubecula (Rhinocryptidae) are prevalent in this location and differ in several life-history traits. This will provide two contrasting cases of several possible life-history strategies in this forest.This study will provide an important contribution to the theoretical framework of habitat fragmentation and will have a direct impact on management plans in the south-temperate rainforest region. Southern South American rainforests are highly threatened and internationally recognized to be of high priority for conservation due to their insular characteristic with high endemism and restricted geographical ranges of most plant and animal species.

本论文增强提案支持密苏里大学圣路易斯分校的John G.Blake博士和Cintia Cornelius女士与智利圣地亚哥Catolica de智利大学的Pablo A.Market博士合作，研究人类驱动的景观变化对鸟类的遗传和人口统计学影响。他们项目的目标是评估栖息地恶化和栖息地碎片化在限制南美南部温带雨林支离破碎景观中森林鸟类数量方面的相对重要性。他们将作为模式系统使用的两种鸟类--刺尾无翼鸟(Aphrastura SPINICODAA)和红腹长尾黄嘴鸟(ScelorChilus Rubecula)--在这个地区很普遍，而且在几个生活史特征上存在差异。这将为这片森林中几种可能的生活史策略提供两个截然不同的案例。本研究将为栖息地破碎化的理论框架提供重要贡献，并将对南温带雨林区的管理计划产生直接影响。南美洲南部热带雨林受到高度威胁，国际公认为高度优先保护，因为它们具有高度特有的岛国特点，大多数动植物物种的地理范围有限。
