Global warming amplifies nitrogen over phosphorus limitation in aquatic ecosystems: A multi-trophic meta-analysis

Nitrogen (N) and phosphorus (P) availability fundamentally regulate the structure and function of aquatic ecosystems. While global-scale patterns of relative nutrient limitation have been increasingly documented, their responses to climate warming remain poorly quantified. To address this, we integrated a global meta-analysis of nutrient enrichment experiments (spanning 510 sites and multiple trophic levels) with large-scale datasets of water chemistry from 3,403 lakes and 13,032 marine sites. Meta-analysis showed that primary producers have the strongest responses to nutrient enrichment, especially NP co-addition, with effects attenuating at higher trophic levels. Increasing temperature amplifies the response of primary producers to nutrient enrichment, but not for consumers, indicating that warming disrupts energy flow to higher trophic levels. Furthermore, relative N limitation of primary producers intensifies with increasing temperature and decreasing latitude in both freshwater and..., , # Global warming amplifies nitrogen over phosphorus limitation in aquatic ecosystems: A multi-trophic meta-analysis

### **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: data1.csv**

The dataset comprises a total of 4,345 data entries derived from 329 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, and bacteria. All variables and units are included in the file named \"README_data1.csv\".
