Figure 2: Histograms plot 3341 observation periods for Shannon entropy change including A) selection, B) immigration, C) rarity shifts and D) total diversity change across all plots and from the 15 studies. Each histogram represents the number of observations where a given partition was of a particular magnitude. To improve readability, we set the x-axis from -1 to 1, excluding a small number (3.7%) of values (see supporting information for further details). Boxplots show median values, interquartile range and values exceeding 1.5 times past the interquartile range.
