项目摘要
The previous phase of the Jena Experiment provided novel empirical evidence that ecological and evolutionary processes are intertwined in determining biodiversity-ecosystem functioning (BEF) relationships, and long-term experiments are key not only to gain a basic understanding of the relative importance as well as interactions of these processes but also to apply these concepts to better provisioning of ecosystem functions and stability. However, this prior research predominantly focused on the magnitude of various ecosystem functions, rather than on their stability, and mechanistic insights into biodiversity-stability relationships are especially lacking. It is thus key to continue developing a whole-ecosystem perspective in BEF research. In this interdisciplinary project, we propose to focus on the biodiversity drivers of ecosystem stability in the second phase of the Research Unit, including temporal stability using unique time series and stability in response to extreme climate events, such as drought, flooding, hot spells, and exceptional frost periods. The main hypothesis is that (multifunctional) stability is highest in high-diversity plots and biodiversity-stability relationships increase over time, due to a variety of forms of ecological complementarity. We propose to utilize a combination of approaches, with experiments in the field, iDiv Ecotron, and microcosms, based on biodiversity-stability theory. In the Main Experiment, we have ~two decades of high-resolution, field-level (air temperature, air moisture, radiation), and plot-specific data (soil temperature and moisture) that will allow us to identify extreme climate events. Synthesizing data from the subplots of the ΔBEF Experiment allow us to study the role of soil history in long-term plant diversity effects on ecosystem functioning and stability. The unique database from multiple long-term experiments, combined with repeated measurements of a multitude of different ecosystem functions, allows us to study how biodiversity can buffer ecosystems as affected by climate extremes. We can also use these long-term plots and their assembled communities and excavate soil to expose them to certain environmental conditions like climate extremes in a controlled way in the iDiv Ecotron. Moreover, we can use soil (respectively selected microbial inocula which are used to form a synthetic microbial community) taken from the long-term Main Experiment to perform small-scale microcosm experiments, to test additional stressors or mechanisms under controlled laboratory or greenhouse conditions. All subprojects will closely collaborate in the field (Main Experiment) as well as in the iDiv Ecotron Experiment (ResCUE Experiment) or central microcosm experiment (DrY Experiment), while smaller teams of subprojects will work together in Complementary Microcosm Experiments (CoMic Experiments). Extensive synthesis work will integrate data and information across subprojects and research platforms.
耶拿实验的前一阶段提供了新的经验证据表明,生态和进化过程交织在一起,在确定生物多样性生态系统功能(BEF)的关系,长期的实验是关键,不仅要获得一个基本的了解的相对重要性,以及这些过程的相互作用,但也适用于这些概念,以更好地提供生态系统功能和稳定性。然而,这种先前的研究主要集中在各种生态系统功能的大小,而不是对它们的稳定性,和生物多样性的稳定性关系的机制的见解是特别缺乏。因此,在BEF研究中继续发展整个生态系统的观点是关键。在这个跨学科的项目中,我们建议在研究单元的第二阶段集中研究生态系统稳定性的生物多样性驱动因素,包括使用独特时间序列的时间稳定性和应对极端气候事件的稳定性,如干旱,洪水,炎热和异常霜冻期。主要的假设是,(多功能)的稳定性是最高的高多样性地块和生物多样性稳定性的关系随着时间的推移,由于各种形式的生态互补性增加。我们建议利用相结合的方法,在现场的实验,iDiv Ecotron,和微观世界,生物多样性稳定性理论的基础上。在主实验中,我们有大约20年的高分辨率,现场水平(气温,空气湿度,辐射)和特定地块的数据(土壤温度和湿度),这将使我们能够识别极端气候事件。综合从ΔBEF实验的子样地的数据,使我们能够研究土壤历史的作用,在长期的植物多样性对生态系统功能和稳定性的影响。来自多个长期实验的独特数据库,结合对多种不同生态系统功能的重复测量,使我们能够研究生物多样性如何缓冲受极端气候影响的生态系统。我们还可以使用这些长期的地块和它们的集合社区,并挖掘土壤,使它们暴露在某些环境条件下,例如在iDiv Ecotron中以受控的方式暴露在极端气候中。此外,我们可以使用从长期主要实验中采集的土壤(分别选择用于形成合成微生物群落的微生物接种物)进行小规模的微观实验,以在受控实验室或温室条件下测试额外的压力源或机制。所有子项目将在现场(主实验)以及iDiv Ecotron实验(ResCUE实验)或中央微观世界实验(DrY实验)中密切合作,而较小的子项目团队将在互补微观世界实验中合作(CoMic实验)。广泛的综合工作将整合各分项目和研究平台的数据和信息。
