U.S.-Chile: Genetic and Demographic Consequences of Human-driven Landscape Changes on Birds: A Case Study Using Aphrastura Spinicauda and Scelorchilus Rubecula

0501012布莱克这份论文增强提案支持密苏里大学圣路易斯分校的约翰·g·布莱克博士和辛蒂亚·科尼利厄斯女士与智利圣地亚哥智利天主教大学的巴勃罗·a·马奎特博士就人类驱动的景观变化对鸟类的遗传和人口影响进行合作。他们项目的目标是评估栖息地退化和栖息地破碎化在南美南部温带雨林破碎景观中限制森林鸟类种群的相对重要性。他们将使用的两种鸟类作为模型系统，即刺蚜鸟（Furnariidae）和rubeculus （Rhinocryptidae）在该地区普遍存在，并且在一些生活史特征上有所不同。这将为这片森林中几种可能的生活史策略提供两个对比的案例。本研究将为南温带雨林地区生境破碎化的理论框架提供重要贡献，并将对南温带雨林地区生境破碎化的管理计划产生直接影响。南美洲南部的热带雨林受到高度威胁，由于其特有的岛屿特征，大多数动植物物种的高度地方性和地理范围有限，因此在国际上被公认为高度优先的保护对象。

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.
