The rates at which journal articles in ecology and evolutionary biology make data and code available have been studied previously. This study examines how often this data and code, when available, can be used to computationally reproduce results published in articles. This study surveys the data and code sharing practices of 177 meta-analyses published in ecology and evolutionary biology journals published over 2015-17. 26 articles (15%) were found to have obtainable data and code files. Results from these articles were targeted for computational reproduction using the data and code files obtained. Overall, from the sample of 177 articles, 4-13% of articles could be successfully reproduced, depending on the stringency of the criteria applied for a successful reproduction. The low overall success rate was primarily driven by the low rate of code sharing.
