Relative importance (vertical) and standardized effect size (±95% confidence intervals) (horizontal) of 5-year journal impact factor, Twitter reach, number of tweets, and time since publication in generalized linear mixed models predicting the number of Web of Science citations of 1,599 primary ecological research articles published in 20 journals between 2012 and 2014.

<p>Note that relative importance of number of tweets is also 1.0, but is offset to display confidence intervals.</p
