Collaborative Research: RUI: LTREB: Behavioral and demographic responses of migratory birds to climate change

预计北美东北部在21世纪世纪的气候变化可能会影响迁徙鸣禽的分布和丰富的数量和质量的栖息地改变他们。对黑喉蓝莺（Dendroica caerulescens）的长期研究表明，气候强烈影响该物种的栖息地质量。本提案的重点是气候变化将如何影响鸟类做出的关键选择：在哪里繁殖（地区选择），是否在随后的一年返回一个地区（现场保真度），以及如何将有限的资源分配到交配和育儿上（生殖努力）。长期-提出的长期研究补充了哈伯德布鲁克生态系统研究中的多项其他研究，重点是生态系统对环境变化的反应。这项研究将通过讲座、教育材料、国际伙伴关系（例如，史密森尼候鸟中心的桥接美洲计划）和基于网络的信息。研究结果对决策者和决策者至关重要，因为它们与生物多样性、公共土地的健康以及公众对鸟类特别是候鸟的更广泛兴趣有着多重联系。

Climate change projected for northeastern North America in the 21st century is likely to influence the distribution and abundance of migratory songbirds by altering the amount and quality of habitat available to them. Long-term studies of Black-throated Blue Warblers (Dendroica caerulescens) have revealed that climate strongly influences habitat quality in this species. The focus of the present proposal is on how a changing climate will affect the key choices that birds make: where to breed (territory selection), whether to return to a territory in a subsequent year (site fidelity), and how to allocate limited resources into mating and parental care (reproductive effort).The long-term research proposed complements multiple other studies within the Hubbard Brook Ecosystem Study that focus on ecosystem responses to environmental change. This research will provide numerous opportunities for undergraduate training and education of the general public through lectures, educational materials, international partnerships (e.g., the Smithsonian Migratory Bird Center's Bridging the Americas program) and web-based information. Results will be of critical interest to policy makers and decision makers because of their multiple connections to biodiversity, the health of public lands and the broader interest of the public in birds, especially migratory songbirds.
