Most coastal ecosystems are faced with novel challenges associated with human activities and climate change such as ocean acidification, warming, eutrophication, and organic pollution. However, data on the independent or combined effects of ocean acidification and warming on coastal eutrophication and organic pollution at present are relatively limited. Here, we applied the generalized additive models (GAMs) to explore the dynamics of coastal eutrophication and organic pollution in response to future climate change in the Bohai Sea. The GAMs reflected the fact that acidification alone favors eutrophication and organic pollution, while warming alone inhibits these two variables. Differently, the interactions between acidification and warming in the future may further exacerbate the organic pollution but may mitigate the progress of eutrophication. These different responses of eutrophication and organic pollution to acidification and warming may be attributed to algae growth and microbial respiration, as well as some physical processes such as stratification.
大多数沿海生态系统面临着与人类活动和气候变化相关的新挑战,如海洋酸化、变暖、富营养化和有机污染。然而,目前关于海洋酸化和变暖对沿海富营养化和有机污染的独立或综合影响的数据相对有限。在此,我们应用广义相加模型(GAMs)来探究渤海未来气候变化下沿海富营养化和有机污染的动态变化。GAMs反映出仅酸化有利于富营养化和有机污染,而仅变暖则抑制这两个变量。不同的是,未来酸化和变暖之间的相互作用可能会进一步加剧有机污染,但可能会减缓富营养化进程。富营养化和有机污染对酸化和变暖的这些不同响应可能归因于藻类生长和微生物呼吸,以及一些物理过程,如分层。
