Meta‐analysis of multiple driver effects on marine phytoplankton highlights modulating role ofp CO 2
Abstract Responses of marine primary production to a changing climate are determined by a concert of multiple environmental changes, for example in temperature, light, p CO 2 , nutrients, and grazing. To make robust projections of future global marine primary production, it is crucial to understand...

Abstract Responses of marine primary production to a changing climate are determined by a concert of multiple environmental changes, for example in temperature, light, p CO 2 , nutrients, and grazing.

This meta‐analysis quantifies individual and interactive effects of dual driver combinations on marine phytoplankton growth rates. Almost 50% of the single‐species laboratory studies were excluded because central data and metadata (growth rates, carbonate system, experimental treatments) were insufficiently reported.
