U.S.-Chile Cooperative Research: Reproductive Success of Endemic Birds in South-Temperate Fragmented Forests

9602917威尔森美洲计划奖将资助波特兰太平洋西北研究站的玛丽·威尔森博士和智利大学胡安·阿梅斯托博士之间的一个合作研究项目，以研究森林碎片化对智利森林中两种特有鸟类Chucao和Huet-Huet的密度和繁殖成功的影响。这项研究的基本工作假设是，在较小、更受干扰的森林片断中，物种的种群密度和/或繁殖成功率较低。在记录了与森林大小相关的这些模式之后，重点将放在碎片化影响鸟类繁殖的可能的生态机制上。智利南部和阿根廷最西部的南温带雨林正在以非常快的速度被砍伐，并正在迅速消失。保护规划需要了解影响种群生存能力的生态机制，以便确定最有效的措施，将区域灭绝的风险降至最低。这项工作的长期目标包括为农业景观中的生物多样性保护开发一个景观级模式。***

9602917 Willson This Americas Program award will fund a collaborative research project between Dr. Mary Willson, Pacific Northwest Research Station, Portland and Dr. Juan Armesto, Universidad de Chile , to examine the effects of forest fragmentation on density and reproductive success of two endemic bird species in the Chilean forest, the chucao and the huet-huet. The fundamental working hypothesis of this study is that population densities and/or reproductive success of the species are lower in smaller, more disturbed forest fragments. After documenting these patterns in relation to forest size, the focus will be on the possible ecological mechanisms by which fragmentation affects the breeding of the birds. The south-temperate rainforests of southern Chile and far- western Argentina are being cut at a very rapid rate and are rapidly disappearing. Conservation planning requires an understanding of the ecological mechanisms that influence population viability in order to determine the most effective measure for minimizing the risks of regional extinction. The long-term goal of this work includes the development of a landscape-level model for biodiversity conservation in an agricultural landscape. ***
