海洋保护区是海洋保护的基石。在全球范围内，海洋保护区的数量和覆盖面正在增加，但在许多人类占主导地位的地区，海洋保护区的实施滞后。在空间和资源竞争激烈的地区，对海洋保护区影响的评估对决策至关重要。在人类占主导地位的地中海，完全保护区只占其表面的0.04%。我们评估了完全保护和部分保护对24个地中海海洋保护区鱼类种群、一些具有重要商业价值的鱼类和海胆的生物量和密度的影响。我们探讨了保护水平与MPA大小、年龄和执行情况之间的关系。结果表明，保护对渔业目标物种有显著的积极影响，而对海胆则有负面影响，因为它们的捕食者从保护中受益。完全保护比部分保护提供更强的效果。完全保护鱼类生物量的好处只与执行MPA的水平有关；在较老、执行得更好以及--有趣的是--较小的MPA中，鱼的密度更高。我们的发现是，即使是小的、执行良好的、完全保护的区域也可以产生显著的生态影响，这对“拥挤的”海洋环境来说是令人鼓舞的。然而，需要更多的数据来评估足够的MPA大小来保护不同迁移率水平的物种种群。
Marine protected areas (MPAs) are a cornerstone of marine conservation. Globally, the number and coverage of MPAs are increasing, but MPA implementation lags in many human-dominated regions. In areas with intense competition for space and resources, evaluation of the effects of MPAs is crucial to inform decisions. In the human-dominated Mediterranean Sea, fully protected areas occupy only 0.04% of its surface. We evaluated the impacts of full and partial protection on biomass and density of fish assemblages, some commercially important fishes, and sea urchins in 24 Mediterranean MPAs. We explored the relationships between the level of protection and MPA size, age, and enforcement. Results revealed significant positive effects of protection for fisheries target species and negative effects for urchins as their predators benefited from protection. Full protection provided stronger effects than partial protection. Benefits of full protection for fish biomass were only correlated with the level of MPA enforcement; fish density was higher in older, better enforced, and —interestingly— smaller MPAs. Our finding that even small, well-enforced, fully protected areas can have significant ecological effects is encouraging for “crowded” marine environments. However, more data are needed to evaluate sufficient MPA sizes for protecting populations of species with varying mobility levels.
