Mesozooplankton community models selection.

Generalized Additive Mixed Models (GAMMs) for the mesozooplankton community: a) α + f, no difference between treatments (Model Trtmt_indep), b) α + fT, pCO2 treatment effect on temporal trends but not in abundance (Model Trtmt_trend), c) αT + f, pCO2 treatment effect on absolute abundance but not on temporal trends (Model Trtmt_absAb) and d) αT + fT, treatment causes differences both in absolute abundance and seasonal trends (Model Trtmt_absAb_trend). Only those species that were present in at least one of the mesocosms more than 9 days (2/3 of the number of days sampled) and only convergent models were used for this analyses. The smoother of all selected models had a p-value

面向中型浮游动物群落的广义加性混合模型（Generalized Additive Mixed Models, GAMMs）：a) α + f模型，各组处理间无差异（模型Trtmt_indep）；b) α + fT模型，pCO₂处理对时间趋势存在影响，但对丰度无作用（模型Trtmt_trend）；c) αT + f模型，pCO₂处理对绝对丰度存在影响，但对时间趋势无作用（模型Trtmt_absAb）；d) αT + fT模型，处理组在绝对丰度与季节趋势两方面均存在差异（模型Trtmt_absAb_trend）。本分析仅纳入在至少一个中型生态箱中出现时长超过9天（占总采样天数的2/3）的物种，且仅使用收敛模型开展本次分析。所有入选模型的平滑项p值
