Data and code for: Combined effects of warming and hypoxia on aquatic ectotherms: A multilevel meta-analysis of physiological and fitness responses

Key Points

This research aims to analyze how warming and hypoxia affect the physiology and fitness of aquatic ectotherms through a comprehensive meta-analysis.
Analysis of 40 independent studies focusing on aquatic ectotherms
Effect-size calculations and multilevel random-effects modelling
Phylogenetic sensitivity analyses using rotl and ape packages
Moderator analyses and publication bias diagnostics
Warming and hypoxia significantly impact physiological and fitness responses
Combined effects of these stressors lead to varied responses in ectotherms
Statistical analyses reveal strong influences on the overall fitness of aquatic ectotherms

Abstract

This repository contains the raw data spreadsheet and R analysis code supporting the meta-analysis published in Comparative Biochemistry and Physiology Part A. The dataset includes effect sizes extracted from 40 independent empirical studies on aquatic ectotherms exposed to warming, hypoxia, and their combination. The R code covers all stages of the analysis pipeline: effect-size calculation, multilevel random-effects modelling (metafor), phylogenetic sensitivity analyses (rotl, ape), moderator analyses, publication bias diagnostics, and figure generation.
