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

预计21世纪北美东北部的气候变化可能会改变候鸟栖息地的数量和质量，从而影响候鸟的分布和数量。对黑喉蓝莺(Dendroica Caerulescens)的长期研究表明，气候对该物种的栖息地质量有很大影响。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)，是否在第二年返回一个地区(地点保真度)，以及如何将有限的资源分配用于交配和父母照料(繁殖努力)。拟议的长期研究补充了哈伯德·布鲁克生态系统研究中的其他多项研究，这些研究侧重于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，史密森候鸟中心的美洲桥梁计划)和基于网络的信息，为普通公众提供大量的本科生培训和教育机会。由于这些结果与生物多样性、公共土地的健康以及公众对鸟类，特别是候鸟的更广泛的兴趣有着多重联系，因此，政策制定者和决策者将非常感兴趣。

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.
