不同尺度的生物成因、季节和随机波动是沿海海洋生境的特征，并调节环境压力。过去大多数关于气候变化影响的研究的相关性被通常故意从实验设计中排除波动而削弱。我们描述了一种用于底栖生物研究的新型室外生态系统（“底栖生物”），该系统允许控制和操纵几个环境变量，同时允许所有自然的原位波动。这是通过连续测量相关变量（例如，温度，pH值，O2, CO2），在控制软件中将这些实时定义为参考值，并通过delta处理模拟目标气候来实现的。后者是在参考值上人为地增加预定义的变化（例如，“变暖”、“酸化”）。我们通过展示四个季节实验的环境数据来说明系统的性能，这些数据加在一起代表了一整年。“基尔户外底栖生物”允许在控制情景下对复杂的底栖生物群落进行接近自然的气候变化实验。
Biogenic, seasonal, and stochastic fluctuations at various scales characterize coastal marine habitats and modulate environmental stress. The relevance of most past studies into climate change impacts is weakened by the usually intentional exclusion of fluctuations from the experimental design. We describe a new outdoor mesocosm system for benthic research (“benthocosms”) which permit the control and manipulation of several environmental variables while admitting all natural in situ fluctuations. This is achieved by continuously measuring the relevant variables (e.g., temperature, pH, O2, CO2) in situ, defining these in real time as reference values in the control software and simulating target climates by delta treatments. The latter constitute the manipulative addition of predefined changes (e.g., “warming”, “acidification”) to the reference values. We illustrate the performance of the system by presenting the environmental data of four seasonal experiments which together represent an entire year. The “Kiel Outdoor Benthocosms” allow realizing near‐natural climate change experiments on complex benthic communities under controlled scenarios.
