Abstract
Global elevated atmospheric CO2 concentration-induced acidification poses a great threat to aquatic organisms worldwide. However, a comprehensive understanding of the response variability to acidification is still lacking, especially in the context of concurrent global warming. Addressing the response patterns of aquatic biota to acidification in the context of warming can facilitate the identification and prediction of probable consequences of global climate change. Acidification had a significant positive effect on primary producers and decomposers, yet a significant negative effect on consumers. We found that invertebrates were the most negatively affected of all organisms, and the marine ecosystems are suffering more severity of acidification than freshwater ecosystems. We further found that the response magnitude showed a significant dose effect, indicating that reducing greenhouse gas emissions would minimize the impact of acidification. In addition, we found that higher temperatures enhanced the sensitivity of primary producers to acidification, suggesting that global climate warming may interact with acidification in a synergistic way.

Files and variables
All variables and units are included in the file named "Readme.csv".
The missing values in the CSV file are due to the fact that the original source did not provide the relevant information, and thus, the data could not be collected.
File: Meta_Biota_Acidification_dryad_data.csv
The dataset comprises a total of 3,669 data entries derived from 221 pieces of literature collected. It primarily encompasses primary producers, consumers, and decomposers of aquatic ecosystems, and includes a total of seven aquatic taxa: phytoplankton, macrophytes, periphytic algae, zooplankton, invertebrates, fish, and bacteria.
File: Map_Sample.csv
The dataset encompasses the latitudes and longitudes of experimental sites, along with the aquatic biota measured at each site, sourced from 221 collected literatures. It includes seven aquatic biota groups: phytoplankton, macrophytes, periphytic algae, zooplankton, invertebrates, fish, and bacteria. In the dataset, a value of 1 indicates that the experimental subject at the site is the corresponding biota group, while a value of 0 indicates that the experimental subject at the site is not the corresponding biota group.
File: Acidification_Code.R
According to the instructions set forth in the provided code, the article’s outcomes can be replicated using the indicated version of the R software and the requisite package.
Code/software
R software (version 4.4.3) and the ‘metafor’ support package were used for statistical analysis of the data.
Version changes
21-May-2025: A 'Year' column, indicating article publication years, was added to the "Meta_Biota_Acidification_dryad_data.csv" file to facilitate subsequent publication bias analysis in R. The ”Map_Sample.csv“ file, containing the geographical coordinates of all experimental sites and their corresponding biota, was added. In the ”Acidification_Code.R“ file, annotations were added, including the installation paths for the orchaRd and metagear R packages.
We performed a meta-analysis by synthesizing 221 studies containing 3669 observations to summarize the effects of CO2 on multiple aquatic biota, including primary producers, consumers, and decomposers. And we further examined the effects of different ecosystems, experimental venue, CO2 concentration, and ambient experimental temperature on the response magnitude.
There were 2818 responses for primary producers (2696 for phytoplankton, 117 for macrophytes, and 5 for periphytic algae), 616 responses for consumers (357 for zooplankton, 137 for invertebrates, and 122 for fish), and 235 responses for decomposers (bacteria).
