项目摘要

Coastal wetlands provide important ecosystem services, such as flood protection, habitat for wildlife, and water quality improvement. Despite the recognition of their valuable services, local land use and global climate change are driving the loss of coastal wetlands. This project will advance our understanding of coastal wetland structure and function, while answering questions relevant to management that can help prevent wetland loss. This project will determine the capacity of North Carolina coastal wetlands to continue to provide ecosystem services under a changing climate. The project will engage middle school teachers, undergraduate and graduate students, and citizen scientists in long-term ecological research by creating new curricula, field based exercises, a graduate course, and a citizen science mobile device application. The project will support three graduate students, five undergraduate students, and four middle school teachers over five years. The project will also advance the career of a young investigator that is a member of an underrepresented group. This research will adapt recently developed methods to identify 'early warning signals' that will indicate the resilience of forested wetlands and marshes to drought, storms, and increased salinity and help forecast the loss of coastal wetlands. The project will use remote sensing, tree ring analyses, field surveys and experiments, and new statistical methods to examine the effects of droughts, storms, and increasing salinity on forested wetlands and marshes. The proposed research will: (1) Determine the spatial extent, time frame, and biogeochemical consequences of forested wetland retreat using a combination of remote sensing and tree ring and sediment cores. (2) Measure the recovery trajectory of ecosystem processes to disturbances in coastal wetlands in different ecosystem states and with varying degrees of management. (3) Test the resilience of ecosystem processes to disturbance in coastal wetlands by conducting a 5-year field experiment.

沿海湿地提供重要的生态系统服务，例如防洪，野生动植物的栖息地和水质改善。尽管认识到其宝贵的服务，但当地的土地使用和全球气候变化仍在推动沿海湿地的丧失。该项目将促进我们对沿海湿地结构和功能的理解，同时回答与管理有关的问题，以帮助防止湿地损失。该项目将确定北卡罗来纳州沿海湿地的能力继续在气候变化下提供生态系统服务。该项目将通过创建新的课程，基于现场的练习，研究生课程以及公民科学移动设备应用程序，使中学教师，本科和研究生以及公民科学家参与长期生态研究。该项目将在五年内为三名研究生，五名本科生和四名中学老师提供支持。该项目还将推进一个年轻的调查员的职业，该调查员是一个人数不足的团体成员。这项研究将适应最近开发的方法来识别“预警信号”，以表明森林湿地和沼泽对干旱，风暴和增加盐分的弹性，并有助于预测沿海湿地的丧失。该项目将使用遥感，树环分析，现场调查和实验以及新的统计方法来检查干旱，风暴和增加盐度对森林湿地和沼泽的影响。拟议的研究将：（1）确定森林湿地静修所带来的空间范围，时间框架和生物地球化学后果，结合了遥感，树环和沉积物核心。（2）测量生态系统过程的恢复轨迹，以不同生态系统状态的沿海湿地的干扰以及不同程度的管理。（3）测试生态系统过程的弹性，通过进行5年的现场实验，以对沿海湿地的干扰。
