项目摘要

The need for long-term research on forest ecosystems has accelerated markedly in recent years. Traditional interests in provision of wood products and clean water have expanded to include climate mitigation, biodiversity conservation, and ecological and social resilience. Forests are complex ecosystems, dominated by long-lived organisms, and are highly connected to adjacent ecosystems at many scales. Long-term research at the Hubbard Brook Experimental Forest has focused on the ecology and management of hardwood forests, with a focus on understanding the role of disturbance in how forest ecosystems work. The research has continually evolved as unexpected observations emerge from long-term studies, raising questions that can only be addressed with continued long-term research. Recent surprises that will be explored in this latest phase of research are: 1) unexpected changes in the elevational distribution of some tree species that have surprisingly migrated downward instead of up-slope as would be expected in response to warming temperatures; (2) abrupt increases in water use by plants over the past 10 years, and (3) significant declines since the 1970s in some species of birds, salamanders, caterpillars, and beetles. The long-term nature of studies at Hubbard Brook has allowed researchers to build deep relationships with stakeholders. These relationships are also evolving, and researchers will diversify them to increase participation of underrepresented groups. Specifically, they will make the lens of research more inclusive and more holistic and will recruit new participants to make the site and community more diverse. The overarching research theme of this project is the long-term response of ecosystem structure, composition, and function to disturbance. The conceptual model underpinning the project envisions three principal types of disturbance acting as drivers of change in the ecosystem: changing atmospheric chemistry, changing climate, and changing biota. The effects of these drivers play out on a biogeophysical template that includes variation across the landscape in topography, geology, soils, vegetation, and history of past disturbance. Within the ecosystem, the disturbances affect the interacting processes of hydrology, biogeochemistry, vegetation, and food web dynamics. The conceptual model is evolving to focus on “control points of change” in the landscape - specific places and times where significant changes will begin or accelerate. The research is integrated with broader impacts activities driven by four goals: (1) establish long-term, trusting relationships with diverse community members and environmental decision-makers across the northern forest ecoregion; (2) recruit and train the next generation of ecosystem scientists and environmental leaders; (3) support diversity, equity, inclusion, and anti-racism (DEI&A) within the site and broader scientific communities; and (4) drive innovations in research, education, and outreach. To achieve these goals, five approaches are planned: public and policy engagement programs, science education and training programs, an art-science program, development and maintenance of infrastructure for DEI&A, and use of a Critical Ecology approach to make the lens of the site’s research more inclusive and holistic.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

近年来，对森林生态系统的长期研究的需求显着加速。提供木材产品和清洁水的传统利益已经扩展到包括气候缓解，生物多样性保护以及生态和社会弹性。森林是复杂的生态系统，以长寿生物为主，并且在许多尺度上都高度连接到相邻的生态系统。哈伯德布鲁克实验森林的长期研究集中在硬木森林的生态和管理上，重点是了解灾难在森林生态系统工作方式中的作用。这项研究不断发展，因为长期研究的意外观察结果出现，这引发了只能通过持续的长期研究来解决的问题。在最新的研究阶段将探索的最新惊喜是：1）某些树种高度分布的意外变化，而某些树种出人意料地向下迁移而不是向上斜坡，这是响应温暖的温度而预期的；（2）在过去的10年中，植物的用水量突然增加，以及（3）自1970年代以来，某些鸟类，sal，毛毛虫和甲虫的大幅下降。哈伯德·布鲁克（Hubbard Brook）研究的长期性质使研究人员能够与利益相关者建立深厚的关系。这些关系也在不断发展，研究人员将使他们多样化以增加。代表性不足的群体的参与。具体来说，它们将使研究镜头更具包容性，更全面，并将招募新的参与者，以使网站和社区更加多样化。该项目的总体研究主题是生态系统结构，组成和功能对灾难的长期响应。该项目支撑的概念模型设想了三种主要类型的灾难类型，充当了生态系统变化的驱动因素：不断变化的大气化学，气候和变化的生物群。这些驱动因素的影响在生物地球物理模板上发挥作用，其中包括在地形，地质，土壤，植被和过去灾难的历史中跨景观的变化。在生态系统中，灾难会影响水文学，生物地球化学，植被和食物网络动态的相互作用过程。概念模型正在演变为专注于景观中的“控制点” - 特定地点和时间，重大变化将开始或加速。这项研究与四个目标驱动的更广泛的影响活动相结合：（1）与北森林生态区的潜水员社区成员和环境决策者建立长期的信任关系；（2）招募和培训下一代生态系统科学家和环境领导者；（3）支持遗址和更广泛的科学社区内的多样性，公平，包容和反种族主义（DEI＆A）；（4）推动研究，教育和外展方面的创新。为了实现这些目标，计划了五种方法：公共和政策参与计划，科学教育和培训计划，ART科学计划，开发和维护DEI＆A的基础架构，以及使用批判性生态学方法来使NSF的法定任务和审查的范围弥补，这表明了该网站研究的范围更具包容性和整体性。
