Daru and Rock¹ used species distribution modelling (SDM) to project widespread reductions in seagrass species’ range sizes and increased endemism under end-of-century climate change. These shifts in alpha diversity were found to be similar across four Representative Concentration Pathway (RCP) scenarios. Global beta-diversity patterns would become more heterogeneous. From their models, Daru and Rock conclude that the redistribution of seagrasses would cause present-day marine protected areas to be ineffective, calling for the prioritization of new conservation areas. However, conceptual and methodological shortfalls in their implementation of SDM undermine accurate estimates of seagrass community reorganization in a changing climate.

Daru 和 Rock ¹ 使用物种分布模型 (SDM) 来预测本世纪末气候变化下海草物种范围的广泛减少和地方性的增加。发现 α 多样性的这些变化在四种代表性浓度途径 (RCP) 情景中是相似的。全球贝塔多样性模式将变得更加异质。达鲁和洛克从他们的模型中得出结论，海草的重新分布将导致目前的海洋保护区失效，因此需要优先考虑新的保护区。然而，实施 SDM 时的概念和方法上的缺陷破坏了对气候变化下海草群落重组的准确估计。
