海洋扩散和连通性已被确定为构建海洋种群和设计海洋保护区的关键因素。专注于幼虫的洋流扩散，我们提出了一种方法耦合拉格朗日运输和网络理论的新工具来表征地中海盆地的海洋连通性。不同的远洋持续时间和季节的larcadium模拟为被动示踪剂平流在模拟海洋表面流，从网络的连接区域的构建。从这个网络中提取的水动力省划定的边界相匹配的多尺度海洋学特征。通过研究这种边界的重复出现，我们确定了控制整个海景的幼虫扩散的空间尺度和地理结构。基于这些流体动力学单元，我们研究了新的连通性度量现有的储备。我们的研究结果进行了讨论的海洋地理和海洋保护区设计的背景下，具有生态和管理的影响。
Oceanic dispersal and connectivity have been identified as crucial factors for structuring marine populations and designing marine protected areas (MPAs). Focusing on larval dispersal by ocean currents, we propose an approach coupling Lagrangian transport and new tools from Network Theory to characterize marine connectivity in the Mediterranean basin. Larvae of different pelagic durations and seasons are modeled as passive tracers advected in a simulated oceanic surface flow from which a network of connected areas is constructed. Hydrodynamical provinces extracted from this network are delimited by frontiers which match multiscale oceanographic features. By examining the repeated occurrence of such boundaries, we identify the spatial scales and geographic structures that would control larval dispersal across the entire seascape. Based on these hydrodynamical units, we study novel connectivity metrics for existing reserves. Our results are discussed in the context of ocean biogeography and MPAs design, having ecological and managerial implications.
