Extended Data Fig. 2: Mean effect size of warming on GHG emissions at sites of different wetland type.
From: Weakening greenhouse gas sink of pristine wetlands under warming

Wetland warming experiments were mainly conducted in three wetland types, that is, fen, bog and wet tundra. The values next to the bars in parentheses are the corresponding effect size (left) and the number of sites (right) in each group. p value is shown if effect size of a group is significant (p < 0.05). p values are derived from the meta-analysis by using the inverse-variance method under a random-effects model. Error bars indicate 95% CIs.
