项目摘要

Because of the slow pace of terrestrial ecosystem processes, including the slow generation time, growth rate, and decomposition rate of trees, the impact of changing climate and disturbance on forests plays out over hundreds of years. For this reason, centennial scale projections of terrestrial ecosystem models are used to anticipate the trajectory of forest response to environmental change. Modelers would like to have data on how forests have changed at regional scales and over hundreds of years to help assess such projections. A rich assemblage of relevant paleoecological data has been collected, but they have not been synthesized into a form that can be incorporated into broad-scale modeling efforts. Funding provided will support the establishment of a paleoecological observatory network (PALEON) to address this challenge. PALEON is an interdisciplinary team of paleoecologists, environmental statisticians, and ecosystem modelers with the goals of producing rigorous and robust reconstructions of forest change from the Atlantic to the Great Plains over the past 2,000 years, and then using these reconstructions to validate and improve the predictions of terrestrial ecosystem models. PALEON has identified the integrated analysis of paleoecological data with statistical and mechanistic modeling as a key challenge for improving research capacity for anticipating the future of environmental change. For this reason, PALEON incorporates interdisciplinary training and community building into all aspects of the PALEON mission. In addition to focused working groups, PALEON works with relevant disciplinary communities to develop common approaches to data collection, analysis, and experimental protocols to ensure that long-term data can be seamlessly integrated into macroscale ecosystem analyses. Interdisciplinary training of post-doctoral fellows and graduate students, including a summer short course, will ensure that the next generation of researchers thinks naturally at the spatial and temporal scales relevant to understanding the broad scale impact of changing climate and land-use disturbance.

由于陆地生态系统进程的缓慢，包括树木的生成时间、生长速度和分解速度缓慢，气候变化和干扰对森林的影响要持续数百年。因此，利用陆地生态系统模型的百年尺度预测来预测森林对环境变化的反应轨迹。建模者希望获得关于森林在区域范围内和数百年来如何变化的数据，以帮助评估这种预测。已经收集了丰富的相关古生态数据，但它们还没有被合成为一种可以纳入大规模建模工作的形式。所提供的资金将用于支持建立一个古生态观测站网络，以应对这一挑战。PALEON是一个由古生态学家、环境统计学家和生态系统建模师组成的跨学科团队，其目标是对过去2,000年来从大西洋到大平原的森林变化进行严格而稳健的重建，然后利用这些重建来验证和改进陆地生态系统模型的预测。PALEON已经确定了将古生态数据与统计和机械建模相结合的综合分析作为提高预测未来环境变化研究能力的关键挑战。因此，PALEON将跨学科培训和社区建设纳入PALEON使命的各个方面。除了重点工作组，PALEON还与相关学科社区合作，制定数据收集，分析和实验协议的通用方法，以确保长期数据可以无缝集成到宏观生态系统分析中。博士后研究员和研究生的跨学科培训，包括夏季短期课程，将确保下一代研究人员在与了解气候变化和土地使用扰动的广泛影响有关的空间和时间尺度上自然地思考。
