摘要

本文总结了通过基因组方法获得的浮游生物生物地理学知识的最新进展以及全球变暖对其的影响。对不同浮游生物大小组分样本的基因组含量进行大规模比较,揭示了海洋被划分为基因组省以及主要洋流对其的影响。通过定义生态位,这些省份被外推到除北冰洋以外的所有海洋。到21世纪末,预计将对这些省份进行重大重组,以应对所研究海洋表面50%以上的高排放温室气体情景。这样的重组可能导致出口产量下降4%。最后,获得定义这一生物地理学的大量浮游生物基因组的组装序列,可以更好地表征各省的基因组含量,并确定构成这些基因组的物种。这些基因组同样能够更好地描述气候变化下浮游生物群落未来的潜在变化。

Plankton biogeography in the 21st century and impacts of climate change: advances through genomics.

This article summarizes recent advances in our knowledge of plankton biogeography obtained by genomic approaches and the impacts of global warming on it. Large-scale comparison of the genomic content of samples of different plankton size fractions revealed a partitioning of the oceans into genomic provinces and the impact of major oceanic currents on them. By defining ecological niches, these provinces are extrapolated to all oceans, with the exception of the Arctic Ocean. By the end of the 21st century, a major restructuring of these provinces is projected in response to a high emission greenhouse gas scenario over 50% of the surface of the studied oceans. Such a restructuring could lead to a decrease in export production by 4%. Finally, obtaining assembled sequences of a large number of plankton genomes defining this biogeography has allowed to better characterize the genomic content of the provinces and to identify the species structuring them. These genomes similarly enabled a better description of potential future changes of plankton communities under climate change.
