Microplastic effects on zooplankton: meta-analysis dataset and code (48 studies; 1,468 effect sizes)
AI summary Read the abstract
This meta-analysis dataset accompanies research pooling data from 48 studies to examine how microplastics affect zooplankton across different environmental conditions. The analysis covers nearly 1,500 effect measurements and found that microplastics pose elevated risks to these tiny aquatic organisms, particularly under warming conditions. This is concerning because zooplankton form the foundation of aquatic food webs that ultimately supply seafood to human diets.
This dataset provides the extracted data used in our systematic review and meta-analysis on the effects of microplastics on zooplankton. It accompanies the manuscript “Meta-analysis Reveals Microplastics Pose High Risks to Zooplankton in a Warming World” (submitted to the Journal of Hazardous Materials). The dataset is organized as three Excel files: 1) EffectSize_Dataset.xlsx Extracted observation-/effect-size–level dataset used for all meta-analyses (n = 1,468 observations from 48 studies). It contains study metadata and experimental descriptors (e.g., year, location, taxon/species, polymer, particle shape/size/color, exposure duration, temperature, feeding, etc.), concentration information (original and standardized units where applicable), endpoint category (growth/survival/reproduction/physiology), and effect-size statistics (effect size and corresponding variance/SE as used in the meta-analysis models). 2) Included_Studies.xlsx Full list of studies included after screening, with bibliographic information (author, year, title, etc.) and identifiers used to link to EffectSize_Dataset.xlsx. 3) Endpoint_Dictionary.xlsx A dictionary mapping the detailed response indicators reported in primary studies to the four endpoint categories used in the meta-analysis (growth, survival, reproduction, physiology). Notes: Missing values are coded as blank/NA. Variable names and endpoint definitions follow the manuscript and supplementary tables/figures. When citing this dataset, please use the DOI assigned upon publication: DOI: [to be added].

Microplastic effects on zooplankton: meta-analysis dataset and code (48 studies; 1,468 effect sizes)
AI summary Read the abstract
This meta-analysis pools data from 48 studies covering nearly 1,500 measurements to assess how microplastics affect zooplankton, the tiny animals at the base of aquatic food chains. The research found that microplastics pose significant risks to zooplankton, especially as water temperatures rise with climate change. Since zooplankton are a critical food source for fish, harm to these organisms can ripple up the food chain to affect the seafood people eat.
An enigma: A meta-analysis reveals the effect of ubiquitous microplastics on different taxa in aquatic systems
AI summary Read the abstract
This meta-analysis pooled data from multiple studies to assess how microplastics affect aquatic organisms including fish, invertebrates, and zooplankton. Results showed that microplastic exposure can reduce feeding, growth, and reproduction across different species, raising concerns about broader impacts on aquatic food webs.
Data for a global meta-analysis of microplastic effects on fauna, plants, and soils
AI summary Read the abstract
Scientists compiled a massive dataset from existing studies to see how microplastics affect animals, plants, and soil around the world, looking at things like growth, reproduction, and behavior. This isn't a new experiment but rather an organized collection of research findings, designed so other scientists can double-check the results and build on them. While the dataset itself doesn't focus directly on human health, understanding how microplastics disrupt plants, animals, and soil matters because these are the foundations of our food supply and ecosystems we depend on.
Functional Trait-Based Evidence of Microplastic Effects on Aquatic Species
AI summary Read the abstract
Researchers merged data from two global meta-analyses on microplastic effects on benthic invertebrates and fish to compare impacts across functional traits, finding that microplastics impair feeding, reproduction, and growth across both vertebrate and invertebrate aquatic species.
Zooplankton exposure to microplastics at the global scale: Influence of vertical distribution and seasonality
AI summary Read the abstract
Researchers compiled a global dataset of variables used to model zooplankton exposure to microplastics, incorporating vertical distribution and seasonality factors to better characterize how different zooplankton depth preferences and seasonal migration patterns influence the degree of microplastic contact across ocean regions.
