Rhodoliths are benthic calcium carbonate nodules accreted by crustose coralline red algae which recently have been identified as useful indicators of biomineral changes resulting from global climate change and ocean acidification. This study highlights the discovery that the interior of rhodoliths are marine biodiversity hotspots that function as seedbanks and temporary reservoirs of previously unknown stages in the life history of ecologically important dinoflagellate and haptophyte microalgae. Whereas the studied rhodoliths originated from offshore deep bank pinnacles in the northwestern Gulf of Mexico, the present study opens the door to assess the universality of endolithic stages among bloom-forming microalgae spanning different phyla, some of public health concerns (Prorocentrum) in marine ecosystems worldwide.
柳珊瑚是由皮壳状珊瑚藻附着碳酸钙形成的底栖碳酸钙结瘤,最近被鉴定为有用的指标,可以反映全球气候变化和海洋酸化导致的生物矿化变化。本研究强调了一个发现,即柳珊瑚内部是海洋生物多样性热点区域,充当着种子库和暂时的储库,其中包含以前未知的生态重要甲藻和甲藻微藻生活史阶段。研究中的柳珊瑚源自墨西哥湾西北部近海深滩尖峰上,本研究为评估在全球海洋生态系统中形成水华的微藻不同门类中内共生阶段的普遍性打开了大门,其中一些与公共卫生有关(拟菱形藻)。
