mesocosmos实验在气候变化研究中越来越受欢迎，因为它们弥补了小规模、不太现实的微观实验与大规模、更复杂的自然系统之间的差距。水生中游环境设计的特征（例如，中游环境体积、研究持续时间和重复性）差异很大，可能影响实验中测量的效应大小的大小和方向。在这篇全球系统综述中，我们旨在通过中生态实验确定气候变暖对水生物种、群落和生态系统的影响类型、方向和强度。此外，我们将研究观察到的影响对几个先验确定的影响调节因子（生态学和方法学）的上下文依赖性。我们的结论将为水生科学家设计中生态实验提供建议，并为科学家、决策者和公众解释实验结果提供指导。方法利用多个在线数据库进行系统检索，从科学文献中收集关于变暖对水生生态系统影响的证据。从相关研究中提取数据，并将其用于随机效应荟萃分析，以估计变暖实验对物种性能、生物多样性和生态系统功能的总体效应大小。实验特征（例如，中生态的大小和形状，复制水平，实验持续时间和设计，生物地理区域，群落类型，交叉操作）将使用亚群分析进一步分析。
BackgroundMesocosm experiments have become increasingly popular in climate change research as they bridge the gap between small-scale, less realistic, microcosm experiments, and large-scale, more complex, natural systems. Characteristics of aquatic mesocosm designs (e.g., mesocosm volume, study duration, and replication) vary widely, potentially affecting the magnitude and direction of effect sizes measured in experiments. In this global systematic review we aim to identify the type, direction and strength of climate warming effects on aquatic species, communities and ecosystems in mesocosm experiments. Furthermore, we will investigate the context-dependency of the observed effects on several a priori determined effect moderators (ecological and methodological). Our conclusions will provide recommendations for aquatic scientists designing mesocosm experiments, as well as guidelines for interpretation of experimental results by scientists, policy-makers and the general public.MethodsWe will conduct a systematic search using multiple online databases to gather evidence from the scientific literature on the effects of warming experimentally tested in aquatic mesocosms. Data from relevant studies will be extracted and used in a random effects meta-analysis to estimate the overall effect sizes of warming experiments on species performance, biodiversity and ecosystem functions. Experimental characteristics (e.g., mesocosm size and shape, replication-level, experimental duration and design, biogeographic region, community type, crossed manipulation) will be further analysed using subgroup analyses.
