An analysis of 199 journals in ecology and evolution finds no link between policies mandating data sharing and the rate of article retraction or correction. The authors position this finding in a broader discussion of open data and code.
The authors use a theoretical model along with competition experiments between two aquatic plant species to show that phenotypic plasticity affects the outcome of competition.
In a meta-analysis comparing experimental versus observational studies of aboveground biomass responses to drought in grasslands, the authors show that effect sizes in experiments are 53% weaker than in observational studies, suggesting that experiments are underestimating drought responses.
