海洋保护区（MPAs）是防止世界海洋生物多样性丧失的重要防御措施，但要实现近期保护效益，必须在生物多样性面临重大威胁的地方建立保护区，并可以减轻这些威胁。我们量化了MPA机构针对威胁的程度（即，通过将2008年和2013年海洋生物多样性受到的空间上明确的威胁数据与关于海洋保护区的位置和制止威胁的潜力的信息相结合，对海洋生物多样性受到的威胁进行了评估。我们计算了一个影响指标，以确定国家是否按比例保护更多的高或低威胁生态区，并将观察值与随机保护区分配进行比较。我们发现保护措施包括
Marine protected areas (MPAs) are a critical defense against biodiversity loss in the world's oceans, but to realize near-term conservation benefits, they must be established where major threats to biodiversity occur and can be mitigated. We quantified the degree to which MPA establishment has targeted stoppable threats (i.e., threats that can be abated through effectively managed MPAs alone) by combining spatially explicit marine biodiversity threat data in 2008 and 2013 and information on the location and potential of MPAs to halt threats. We calculated an impact metric to determine whether countries are protecting proportionally more high- or low-threat ecoregions and compared observed values with random protected-area allocation. We found that protection covered
