Results from nutrient analyses and physiological responses of the different components of the model communities.

Measurements made at start (start), after five weeks (4.5w and 5w), and/or after six weeks (6w) exposure to propranolol in 0 (Control); 100 μg l−1 (P100) and 1000 μg l−1 (P1000), mean ± se. dw = dry weight, ww = wet weight, C = carbon. *Denotes significant differences from the respective control treatments (*p本数据集记录了不同处理组暴露于普萘洛尔（propranolol）后的相关测量结果，测量时点涵盖初始时刻（start）、暴露5周后（4.5w与5w）以及/或暴露6周后（6w）。实验设置了0浓度对照组（Control）、100微克每升（100 μg·L⁻¹，记为P100）与1000微克每升（1000 μg·L⁻¹，记为P1000）三个实验组，所有数据以平均值±标准误（standard error，缩写SE）表示。其中dw代表干重（dry weight），ww代表鲜重（wet weight），C代表碳含量。*表示与对应对照组存在显著差异（*p
