Effects of a minimum residence time or b invasion status on the competitive effect (slope of species-specific regressions). In a size of circles shows the square root of the inverse of the standard error of the slope to illustrate weights of data points. The grey dashed line shows the regression line without weighting for comparison. In b the asterisks show the mean competitive effect per invasion status group (in black, in grey for the model without weighting).
