Deforestation of coastal watersheds is occurring throughout the tropics, altering transport of water, nutrients and sediments to mangrove estuaries and coastal oceans. This occurs because of powerful couplings linking land use changes on upland watersheds to receiving aquatic ecosystems down the topographical gradient. This research uses innovative multidisciplinary ecological, hydrological and biogeochemical approaches along six transects in Panama from watersheds subject to different degrees of deforestation to coastal mangroves. This layout will enable testing of hypotheses relating deforestation to functioning of mangrove ecosystems. Results will provide a fresh view of how coastal zones are organized and how human activities reshuffle natural couplings. The work will be based in the Liquid Jungle Laboratory, a research station that permits doing modern research in a remote setting.Broader impacts of the work include definition of the connections between land use practices and conditions in adjoining mangroves in tropical coastal areas. Results will furnish information needed for assessing impacts of deforestation on coastal mangrove ecosystems that provide a series of economically valuable ecological services, such as fish and shellfish nurseries, interception of land derived nutrients, export of energy rich materials, stabilization of shorelines, maintenance of biodiversity, and various harvestable yields. An education and outreach program will focus on training U.S. and Latin American postdoctoral, graduate and undergraduate students. Strong collaborations with Panamanian and Argentine colleagues will enable bilingual websites, presentations and new programs to help transfer results to local people, managers, decision-makers, and scientific colleagues by digital, printed and oral means.

沿海流域的森林砍伐在整个热带地区都发生，改变了水，养分和沉积物向红树林和沿海海洋的运输。之所以发生这种情况，是因为强大的耦合将高地流域上的土地使用变化与接收地形梯度下的水生生态系统联系起来。这项研究使用了创新的多学科生态，水文和生物地球化学方法，沿着巴拿马的六个横断面，从分水岭受到不同程度的森林砍伐到沿海红树林的影响。这种布局将实现与红树林生态系统功能有关的假设的测试。结果将为沿海地区的组织方式以及人类活动如何改组自然耦合提供新的视野。这项工作将基于液体丛林实验室，该研究站允许在远程环境中进行现代研究。该作品的影响包括对热带沿海地区的毗邻红树林之间的土地使用实践与条件之间的联系的定义。结果将提供评估森林砍伐对沿海红树林生态系统的影响所需的信息，这些信息提供一系列经济有价值的生态服务，例如鱼类和贝类托儿所，土地衍生的养分的拦截，富含能源的富含能源富含能源的材料，稳定海岸线的稳定性，维持生物多样性的维持以及各种收获的产量。一项教育和外展计划将专注于培训美国和拉丁美洲博士后，研究生和本科生。与巴拿马和阿根廷同事的强大合作将使双语网站，演示和新计划有助于通过数字，印刷和口头方式将结果转移给当地人，经理，决策者和科学同事。
