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

小行星9602917 该美洲方案奖将资助波特兰太平洋西北研究站的玛丽·威尔逊博士和智利大学的胡安·阿梅斯托博士之间的一个合作研究项目，以研究森林破碎化对智利森林中两种特有鸟类（chucao和huet-huet）的密度和繁殖成功率的影响。 这项研究的基本工作假设是，人口密度和/或繁殖成功的物种是较低的较小，更受干扰的森林片段。 在记录了这些模式与森林规模的关系之后，重点将放在破碎化影响鸟类繁殖的可能生态机制上。 智利南部和阿根廷远西部的南温带雨林正在以非常快的速度被砍伐，并迅速消失。 保护规划需要了解影响种群生存能力的生态机制，以确定最有效的措施，最大限度地减少区域灭绝的风险。 这项工作的长期目标包括开发一个农业景观生物多样性保护的生态系统级模型。 ***

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. ***
