anthoDiv - Linking organismal and genetic diversity of floral microbiomes to ecosystem properties and functional plant traits

与植物地上部分相关的细菌群落对植物健康至关重要。这些物质的组成被认为是由其原始来源如土壤决定的，但也由植物性状如碳和氮的可用性或次级代谢物的组成决定。虽然花与植物的健康和繁殖直接相关，但花圈的细菌定殖者的特征不太清楚，与叶片相关的细菌相比，它们的生态作用也不太清楚。此外，其多样性的决定因素以及对环境梯度的反应，如土地利用强度的变化是未知的。通过使用生物多样性探索站的层次组织，我们计划调查植物微生物的有机体和遗传α-，β-和γ-多样性作为土地利用，植物多样性和功能性花卉性状，如花香和碳和氮的可用性的函数，以了解这些不同层次的生物多样性之间的联系。这些数据将使我们能够衡量环境和植物因素的相对重要性。因此，我们的研究结果将提供一个新的视角，细菌和花卉之间的关联，并有助于了解人为改变的环境对生物和遗传多样性的影响。

Bacterial communities associated to above-ground plant parts are crucial for plant health. The composition of these is considered to be determined by their original sources such as soil but also by plant traits as the availability of carbon and nitrogen or the composition of secondary metabolites. Although flowers are directly linked to plant fitness and reproduction, bacterial colonizers of the anthosphere are less well characterized and their ecological roles are less well understood compared to bacteria associated with leaves. Additionally, the determinants of their diversity as well as their responses to environmental gradients such as variation in land-use intensity are unknown. By using the hierarchical organization of the biodiversity exploratories, we are planning to investigate the organismal and genetic alpha-, beta- and gamma- diversity of floral microbiomes as a function of land-use, plant diversity, and functional flower traits such as floral scents and the availability of carbon and nitrogen in order to understand links between these different levels of biodiversity. These data will allow us to gauge the relative importance of environmental and plant-based factors. Thus, our results will provide a novel perspective on associations between bacteria and flowers and help to understand effects of anthropogenic alterations of the environment on organismal and genetic diversity.
