Fig. 2: Predictors of thermophilisation rates across realms and taxonomic groups.
From: Warming underpins community turnover in temperate freshwater and terrestrial communities
The points show mean effect sizes of temperature change, average community body size, mean thermal niche breadth, baseline mean annual temperature, time-series length and species richness on the rates of thermophilisation. a, e are for all the taxonomic groups for the terrestrial and the freshwater realms, respectively; (b−d) and (f−h) are each taxonomic group: plants, terrestrial insects, and birds (b−d), and zooplankton, aquatic insects, and fish (f−h). We also estimated the interaction effects of body size, thermal niche breadth, baseline temperature and temperature change. Effect sizes with gray circles are not significantly different from zero based upon error bars represent 95% confidence intervals are overlapping zero. Please note that the x-axis range differs among the panels. We applied mixed-effects modelling approach (two-sided). For each realm, effect sizes were calculated after removing outliers that lie beyond two standard deviations from the mean, and after accounting for the effects of taxonomic group (random factor), study ID (random factor) and spatial autocorrelation. Sample size information is given in Supplementary Tables S1−S3. Silhouettes were created with BioRender.com.
