In the last phase of the Biodiversity Exploratories, both the large-scale field experiments and the common garden EXClAvE have been established to quantify the relative effects of individual components of land use (mowing and fertilizer additions) and their combinations on the diversity and functionality of ecosystems. To track morphological and physiological responses of communities, we established digital whole-community phenotyping using a plant scanner (PlantEye F500, Phenospex, Heerlen, The Netherlands) that captures plant communities in 3D and adds multispectral information to the 3D information. We found that plant communities show short-term responses in morphological and physiological properties to land use treatments, but not in species composition. In the proposed project, I will a) track the temporal trajectory of community responses to experimental land-use treatments; b) compare morphological and physiological responses of plant communities in the common garden and in the REX / LUX experiments to generate general rules of community responses to land use changes; and c) to perform a greenhouse experiment to track responses in plant morphology, physiology, and microbiome to experimental land use treatments in four selected species to estimate how interspecific variation in responses contributes to community-wide effects. Therefore, the proposed project builds upon data of the Biodiversity Exploratories and EXClAvE, provides new data to the Biodiversity Exploratories, stands alone as a novel contribution to the question on how land use affects ecosystems, and will contribute to a mechanistic understanding of community responses to land use components.

在生物多样性探索站的最后阶段，建立了大规模实地实验和共同花园EXClAvE，以量化土地利用的各个组成部分（割草和施肥）及其组合对生态系统多样性和功能的相对影响。为了跟踪群落的形态和生理反应，我们使用植物扫描仪（PlantEye F500，Phenospex，海尔伦，荷兰）建立了数字全群落表型，该扫描仪以3D方式捕获植物群落并将多光谱信息添加到3D信息中。我们发现，植物群落的形态和生理特性表现出短期的响应，土地利用处理，但不是在物种组成。在本研究中，我将a）追踪群落对实验性土地利用处理的响应的时间轨迹; B）比较普通花园和雷克斯/ LUX实验中植物群落的形态和生理响应，以得出群落对土地利用变化响应的一般规律;和c）进行温室实验以跟踪植物形态学，生理学，和微生物组，在四个选定的物种中进行实验性土地利用处理，以估计种间反应的变化如何对全社区的影响做出贡献。因此，拟议的项目建立在生物多样性勘探站和EXClAvE的数据，提供新的数据的生物多样性勘探站，独立作为一个新的贡献的问题，土地利用如何影响生态系统，并将有助于机械地了解社区的反应，土地利用的组成部分。
