Studies across ecological context variables. The brown points (and histograms) show data for studies, while blue points (and histograms) describe the range of all ecological contexts across the Arctic study region at 100 × 100 km resolution. Sample size refers to the number of studies with data (i.e., non NA-values). When sample size is given next to the figure subtitle it refers to both variables. When it is given along x and y axis titles, it refers to the specific variable. Note that in these cases the histograms are showing all available data for each of the variables, even though the points are not. For example, histogram for “change in temperature” includes all 662 data points even though only 455 can be plotted against change in NDVI, due to missing data for NDVI
