瓜纳-托洛马托-马坦萨斯（GTM）系统是美国佛罗里达州东北部一个水质良好的河口，其特点是牡蛎的丰度非常高，与欧美定居者所描述的种群相似。从历史上看，密集的牡蛎种群，如在GTM中发现的牡蛎，被认为在水过滤中起着重要作用；然而，大多数试图模拟这一角色的研究团队并没有获得如此强大的种群来参数化他们的模型。为了量化GTM中东部牡蛎（Crassostrea virginica）在多个空间尺度（即珊瑚礁、流域、河口）上的过滤服务（FS），我们实施了一个模型，该模型解决了通过模型牡蛎种群的流体动力学和颗粒物消耗问题，后者来自详细的海湾范围调查。模型结果表明，生长在GTM的牡蛎礁在其停留时间内过滤了河口约60%的体积，对水质起着重要的作用。我们的方法梳理了珊瑚礁大小、停留时间、颗粒浓度和其他物理因素在不同空间尺度上产生offs的作用。发现下游效应对河口fs非常重要，这取决于GTM中珊瑚礁的空间分布以及局地和河口尺度的水动力。因此，当考虑到复杂的水动力和种群之间在几个尺度上的连通性时，给定珊瑚礁的“已实现”fso和“潜在”fso之间的差异可能是巨大的。我们的模型结果为这些牡蛎种群的管理和生态系统服务的保护提供了明确和可操作的信息。
The Guana-Tolomato-Matanzas (GTM) system is a well-flushed estuary in Northeastern Florida, USA, and characterized as having an extraordinarily high abundance of oysters that resembles the populations described by Euro-American settlers. Historically, dense populations of oysters, such as those found in GTM, are believed to play an important role in water filtration; however, most research teams seeking to simulate this role have not had access to such robust populations to parametrize their models. To quantify the filtration service (FS) of Eastern oysters (Crassostrea virginica) in GTM at several spatial scales (i.e., reef, watershed, estuary), we implemented a model that solves for the hydrodynamics and depletion of particulate matter passing over model oyster populations, the latter of which were derived from detailed bay-wide surveys. The model results suggested that oyster reefs populating the GTM play an important role in water quality by filtering ~60% of the estuary’s volume within its residence time. Our approach teases apart the role of reef size, residence time, particle concentration, and other physical factors on the generation ofFSat different spatial scales. Downstream effects were found to be very important for estuaryFS, which depend on the spatial distribution of the reefs in the GTM and local and estuarine-scale hydrodynamics. Therefore, the difference between “realized”FSand the “potential”FSof a given reef may be substantial when considering the complex hydrodynamic and connectivity among populations at several scales. Our model results provide clear and actionable information for management of these oyster populations and conservation of their ecosystem services.
