The JSPS Kakenhi Grant-in-aid for Research Start-up award has allowed me to begin research on my topic of response diversity. I have thus far bought many of the necessary equipment for my upcoming experiment (commencing June 2023) and have hired a research assistant to help with the experiment. Specifically, I have purchased 75 large plastic buckets, which will act as "mesocosms" for floating plant communities, as well as the necessary chemicals to keep the plants alive and to add Nitrogen stress. I will soon purchase a camera lens to keep daily photographs to measure plant growth, and will collect the plants locally to begin the experiment next month. My goal is to experimentally manipulate the number of plant species in each mesocosm and the amount of nitrogen plants are exposed to. Together, this will allow me to test whether the range of growth rates among species (that is, the response diversity of those plants to Nitrogen) affects their temporal variability (stability), which is a vital parameter for ensuring consistent ecosystem functioning.

JSPS Kakenhi Grant-in-Aid for Research Startup award让我开始对我的反应多样性主题的研究。到目前为止，我已经为即将到来的实验（从2023年6月开始）购买了许多必要的设备，并聘请了一名研究助理来帮助实验。具体来说，我已经购买了75个大塑料桶，它们将作为漂浮植物群落的“中型生态系统”，以及保持植物存活和增加氮压力所需的化学物质。我将很快购买一个相机透镜，以保持每天的照片，以衡量植物的生长，并将收集当地的植物开始下个月的实验。我的目标是通过实验来控制每个围隔生态系统中植物物种的数量和植物暴露在氮中的数量。总之，这将使我能够测试物种之间的生长速率范围（即这些植物对氮的反应多样性）是否会影响它们的时间变异性（稳定性），这是确保生态系统功能一致的重要参数。
