This project will address two topics. i) A global assessment of the biodiversity and biogeography of the pelagic Roseobacter clusters based on samples and data collected during two cruises in the Pacific in 2016 and 2017 and previous cruises in the Atlantic and Southern Oceans. We will establish a detailed predictive model of the global functional biogeography of this group. ii) Interactions of roseobacters with the diatom Thalassiosira rotula. We will focus on direct physical interactions between both partners and associated physiological and chemical features and apply increasing levels of complexity from batch and continuous cultures with two and three partners to mesocosm and field studies.

该项目将讨论两个主题。 i) 根据 2016 年和 2017 年太平洋两次航行以及之前大西洋和南大洋航行期间收集的样本和数据，对中上层玫瑰杆菌群的生物多样性和生物地理学进行全球评估。我们将建立该类群全球功能生物地理学的详细预测模型。 ii) Roseobacters 与硅藻 Thalassiosira rotula 的相互作用。我们将重点关注合作伙伴之间的直接物理相互作用以及相关的生理和化学特征，并将从具有两个和三个合作伙伴的批量和连续培养中不断增加的复杂性应用于介观和现场研究。
