Fig. 2: Changes in trait assemblages.
From: Trait mediation explains decadal distributional shifts for a wide range of insect taxa
Predicted average habitat breadth (A), insect size (B) and voltinism (C) across the 1990–2020. Predictions are produced at random locations across the three latitudinal slices of Great Britain (i.e. red curves in Fig. 1B). Uncertainty (90% prediction intervals) arises for the bagged models (n = 20). Ordinate units are standardised (centred reduced) trait values. The dotted black lines are included to show the direction of the linear trend. The solid lines mark the significant (two-sided t test, p = 0.01, n = 620, adjusted for multiple comparisons testing with Bonferroni correction) linear trends with absolute effect size above 1% (or 2%) standard deviation (σ) of the trait value per decade. Source data are provided as a Source Data file.
