COLLABORATIVE RESEARCH RUI INFLUENCE MANGROVE

项目摘要

The marshes and mangroves that line our coasts protect human populations from large storms and provide recreational activities for millions of people. The very existence of these coastal ecosystems depends on their ability to gain soil to keep pace with rising seas. Wetland plant root growth pushes the soil surface upward relative to the ocean, but not all plants do this in the same way. Large areas of southeastern US coastal wetlands have converted from grassy marshes to woody mangrove forests as temperatures have increased over the past decades, possibly enhancing the capacity of these ecosystems to resist storms and build soil. Using experiments that simulate future ecosystems, the team of scientists will investigate how Florida wetlands, both marshes and mangroves, will continue to protect people as both temperatures and seas continue to rise. They will use their results to perform an economic assessment of these changing coastal ecosystems at three Florida reserves used heavily by the public. In addition to advancing understanding of coastal ecosystem responses to varying climate, results from their assessment will be used to 1) inform federal, state and local land managers about the changing coastal protection value of their lands and 2) educate visitors about these special coastal landscapes.Mangrove invasion could change the nature of root inputs and potentially alter soil elevation. Warming could also accelerate microbial decomposition of organic matter and thus decrease or reverse soil accumulation, which could put wetlands at risk in the face of rising seas. The research team will address the question: How do warming and mangrove invasion into salt marshes alter root productivity and organic matter decomposition, mechanisms that control coastal wetland viability? Using six existing research sites along the East Coast of FL, passive warming chambers and mesocosm experiments, the investigators propose to examine the countervailing influences of rising temperatures and plant invasion on soil elevation gain. The team will conduct warming experiments at each of three FL coastal wetland sites, which will be some of the first warming experiments in tropical and subtropical climates, thus filling a major gap in scientific knowledge. In order to assess how a variable climate and mangrove invasion will alter the coastal protection capacity of FL wetland ecosystems, the investigators will perform a natural capital assessment at these sites using the InVEST software developed by the Natural Capital Project. They will use this ecosystem service assessment to develop a 3D video informing visitors to these reserves of how their public lands are changing.

我们海岸的沼泽和红树林保护人口免受大风暴的影响，并为数百万人提供娱乐活动。这些沿海生态系统的存在取决于它们获得土壤以保持海洋越来越高的能力。湿地植物的根生长会将土壤表面向上推向海洋，但并非所有植物都以相同的方式这样做。在过去的几十年中，随着温度的升高，美国东南部沿海湿地的大片地区已从草沼泽转变为伍迪红树林，可能会增强这些生态系统抵抗暴风雨和建造土壤的能力。利用模拟未来生态系统的实验，科学家团队将调查佛罗里达湿地（沼泽和红树林）如何继续保护人们，因为温度和海洋都会继续升高。他们将利用他们的结果对公众大量使用的三个佛罗里达储备中这些不断变化的沿海生态系统进行经济评估。除了促进对沿海生态系统对各种气候的反应的了解外，其评估结果还将用于1）向联邦，州和地方土地经理提供有关其土地不断变化的沿海保护价值的信息，以及2）对这些特殊的沿海景观进行教育.Mangrove入侵可以改变根输入的性质，并可能改变土壤升高。变暖还可以加速有机物的微生物分解，从而减少或反向土壤积累，这可能会使湿地面对海洋的危险。研究小组将解决以下问题：变暖和红树林入侵盐沼泽如何改变根源生产力和有机物的分解，控制沿海湿地可行性的机制？研究人员建议使用佛罗里达州东海岸的六个现有研究地点，被动的变暖室和中库实验，提议研究温度上升和植物入侵对土壤升高增益的反击影响。该团队将在三个佛罗里达州沿海湿地站点中的每个地点进行变暖实验，这将是热带和亚热带气候中的一些最早的变暖实验，从而填补了科学知识的主要空白。为了评估可变气候和红树林的入侵将如何改变FL湿地生态系统的沿海保护能力，研究人员将使用自然资本项目开发的投资软件在这些站点进行自然资本评估。他们将使用此生态系统服务评估来开发一个3D视频，告知访客以了解其公共土地的变化。
