Although coral reefs support the largest concentrations of marine biodiversity worldwide, the extent to which the global system of marine-protected areas (MPAs) represents individual species and the breadth of evolutionary history across the Tree of Life has never been quantified. Here we show that only 5.7% of scleractinian coral species and 21.7% of labrid fish species reach the minimum prote...

Systems of marine spatial planning (MSP) are now being introduced in many countries, with the intention more rational arrangement maritime uses and interests. It would be expected that conservation, especially designation protected areas (MPAs), incorporated into MSP. In practice, however, MSP MPA often taking place parallel to each other, relatively little integration between them, partly beca...

The integration of ecological and evolutionary data is highly valuable for conservation planning. However, it has been rarely used in the marine realm, where the adequate design of marine protected areas (MPAs) is urgently needed. Here, we examined the interacting processes underlying the patterns of genetic structure and demographic strucuture of a highly vulnerable Mediterranean habitat-formi...

Areas beyond national jurisdiction (ABNJ) lie outside the 200 nautical mile limits of national sovereignty and cover 58% of the ocean surface. Global conservation agreements recognize biodiversity loss in ABNJ and aim to protect ≥10% of oceans in marine protected areas (MPAs) by 2020. However, limited mechanisms to create MPAs in ABNJ currently exist, and existing management is widely regarded ...

Idealized normal-mode baroclinic wave simulations are conducted to examine the impact of continuousmesh refinement compared with stepwise changes in resolution using nested grids. The nested-grid results are produced using theAdvancedResearchWeatherResearch andForecasting (WRF-ARW)Model, hereafterARW, and the continuous refinement results are produced using the atmospheric component of the Mode...

The rapid increase in the science and implementation of marine protected areas (MPAs) around the world in the past 15 years is now being followed by similar increases in the science and application of marine ecosystem-based management (EBM). Despite important overlaps and some common goals, these two approaches have remained either separated in the literature and in conservation and management ...

Marine protected areas (MPAs) can facilitate recovery of diminished stocks by protecting reproductive adults. To effectively augment fisheries, however, reproductive output must increase within the bounds of MPAs so that larvae can be exported to surrounding areas and seed the region. In response to dramatic declines of rockfishes (Sebastes spp.) in southern California by the late 1990s two lar...

MPAs(Massively Parallel Architectures) should address two fundamental issues for scalability: synchronization and communication latency. Dataaow ar-chitectures cause problems of excessive synchronization costs and ineecient execution of sequential programs while they ooer the ability to exploit massive parallelism inherent in programs. In contrast, MPAs based on von Neumann computational model ...
