Hurricanes affect coastal landscapes in the context of ongoing sea-level rise. This project will test the hypothesis that disassembly of ecosystems from winds and high water interacts with increased salinity from storm-surges and sea-level rise to influence regeneration by plants and associated mycorrhizal fungi, causing landward shifts in species distributions and reassembly of ecosystems. The study site, Weeks Bay National Estuarine Research Reserve (WBNERR), Alabama, is experiencing chronic sea-level rise. Hurricane Ivan (2004) caused wind damage and a moderate-salinity storm-surge. Hurricane Katrina (2005) caused an extended high-salinity storm-surge and extensive redistribution of sediments. Pre/post-Ivan vegetation surveys and post-Ivan/pre-Katrina sediment cores provide baseline data. Sediments at different elevations will be re-cored to assess biophysical changes. Changes in vegetation will be measured in permanent plots along transects from estuarine marshes to terrestrial forests and in local areas of intense wind/water damage. By combining global climate change science with coastal disturbance ecology, this research will facilitate practical restoration and management in coastal areas experiencing hurricanes and sea level rise. In collaboration with WBNERR, results will be disseminated to professional audiences and will expose ~5,000 visitors annually to interactive effects of hurricanes and global climate change on coastal habitats along the Gulf of Mexico.

在持续的海平面上升的背景下，飓风会影响沿海景观。该项目将检验以下假设：生态系统与风和高水的拆卸与暴风雨和海平面的盐度相互作用，以及海平面的升高，从而影响植物的再生以及相关的菌根真菌的再生，从而导致物种分布中的陆地变化和生态系统的重新组合。阿拉巴马州周年湾国家河口研究保护区（WBNERR）研究地点正在经历慢性海平面上升。伊万（Ivan）飓风（2004）造成了风损和中等层次的暴风雨。卡特里娜飓风（2005）造成了延长的高含量暴风雨和广泛的沉积物重新分布。前/ivan后植被调查以及ivan/katrina前沉积物核心核心提供基线数据。不同海拔的沉积物将被重新估算以评估生物物理变化。植被的变化将在从河口沼泽到陆地森林和巨大风/水损坏的地方的横断面中的永久地块中测量。通过将全球气候变化科学与沿海干扰生态学相结合，这项研究将促进经历飓风和海平面上升的沿海地区的实践恢复和管理。与WBNERR合作，结果将传播到专业的受众群体中，并将​​暴露约5,000名游客对飓风和全球气候变化对墨西哥湾沿海栖息地的互动影响。
