Ecological significance, biogeography and physiology of the Roseobacter group in pelagic systems (A01)

该项目将涉及两个主题。i）根据2016年和2017年在太平洋的两次巡航以及以前在大西洋和南大洋的巡航收集的样本和数据，对远洋Roseberry集群的生物多样性和生物地理学进行全球评估。我们将建立一个详细的预测模型的全球功能神经网络的这一组。ii）roseobacters与硅藻Thalassiosira rotula的相互作用。我们将专注于两个合作伙伴和相关的生理和化学特征之间的直接物理相互作用，并从两个和三个合作伙伴的批量和连续培养中应用越来越多的复杂性。

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.
