最近，人们对生境破碎化在推动生物多样性丧失方面的重要性进行了辩论。虽然栖息地丧失的负面影响是有据可查的，但栖息地破碎化的影响与栖息地丧失无关（例如，栖息地配置）更加模棱两可。在过去的审查中，海洋生态系统的代表性不足，但由于能量/物质流动的性质、大多数海洋物种的开放式种群结构和狭窄的生境范围，海洋生态系统对生境破碎化的反应可能与陆地系统有根本的不同。我们进行了系统的文献综述和荟萃分析的影响栖息地破碎化在海洋ecosystem.Recent FindingsIn我们的审查180研究从28篇文章，我们发现，栖息地破碎化的影响往往是负面的，而不是正面的，虽然整体的平均效果没有从零不同。有趣的是，当响应是丰度、生物多样性或种群/生态系统稳定性的量度时，平均效应是正的。生境破碎化有压倒性的负面影响，当它涉及水文破碎化。我们发现一些支持破碎化阈值假说，通过一个弱的负相关关系栖息地覆盖率在景观和栖息地破碎化effect. SummaryResultsofthis审查对海洋生态系统中的栖息地破碎化的影响是在很大程度上与另一个最近的审查发现，栖息地破碎（与生境丧失无关）对生物多样性没有持续的负面影响，在许多情况下可能增加生物多样性。未来的工作应该集中在驱动这种变异性的因素，并采用多尺度框架来测试补丁和补丁规模的研究之间的一致性。
Purpose of the ReviewThe importance of habitat fragmentation in driving biodiversity loss has been recently debated. While the negative effects of habitat loss are well-documented, the effects of habitat fragmentation independent of habitat loss (e.g., habitat configuration) are more equivocal. Marine ecosystems have been underrepresented in past reviews, yet may differ fundamentally from terrestrial systems in their responses to habitat fragmentation because of the nature of energy/material flow, open population structure of most marine species, and narrow habitat extents. We conducted a systematic literature review and meta-analysis on the effects of habitat fragmentation in marine ecosystems.Recent FindingsIn our review of 180 studies from 28 articles, we found that habitat fragmentation effects were more often negative than positive, although the overall mean effect did not differ from zero. Interestingly, the mean effect was positive when the response was a measure of abundance, biodiversity, or population/ecosystem stability. Habitat fragmentation had overwhelmingly negative effects when it involved hydrological fragmentation. We found some support for the fragmentation threshold hypothesis via a weak negative relationship between habitat percent cover in the landscape and the habitat fragmentation effect.SummaryResults of this review on the effects of habitat fragmentation in marine ecosystems are largely consistent with another recent review finding that habitat fragmentation (independent of habitat loss) does not have consistent, negative impacts on biodiversity, and in many cases may increase biodiversity. Future work should focus on factors driving this variability and employ multi-scale frameworks to test for congruence between patch- and landscape-scale studies.
