影响阳光照射海域真核浮游生物生物地理学的整体因素，这一成果由法国巴黎高等师范学院生物学研究所(IBENS)Hélène Morlon和Guilhem Sommeria-Klein课题组经过不懈努力而取得。该研究于2021年10月29日发表于国际学术期刊《科学》杂志。

在本研究中，研究人员使用覆盖所有主要海洋盆地的Tara Oceans元条形码数据，结合分类群共有的概率模型比较了70种主要真核浮游生物群的生物地理学。研究人员发现了生物地理变异的两个主轴。首先，具有更加多样化的群体显示出更清晰的生物地理模式。其次，大型消费者依赖于海洋盆地，主要取决于水流系统，而小型光养生物则由纬度决定并遵循当地的环境条件。该研究突出了浮游生物群落生物地理学的显著差异，并探究了影响其全球分布的决定因素。 

据了解，真核浮游生物是海洋生态系统的核心组成部分，具有特殊的分类和生态多样性，但对于它们的生态多样性如何与环境相互作用以影响其全球分布却知之甚少。

Abstract: Eukaryotic plankton are a core component of marine ecosystems with exceptional taxonomic and ecological diversity, yet how their ecology interacts with the environment to drive global distribution patterns is poorly understood. In this work, we use Tara Oceans metabarcoding data, which cover all major ocean basins, combined with a probabilistic model of taxon co-occurrence to compare the biogeography of 70 major groups of eukaryotic plankton. We uncover two main axes of biogeographic variation. First, more-diverse groups display clearer biogeographic patterns. Second, large-bodied consumers are structured by oceanic basins, mostly through the main current systems, whereas small-bodied phototrophs are structured by latitude and follow local environmental conditions. Our study highlights notable differences in biogeographies across plankton groups and investigates their determinants at the global scale.
