Fig. 3: Variation in phenological sensitivity.
From: Bird populations most exposed to climate change are less sensitive to climatic variation
Phenological sensitivity (days advanced/C) differed between habitat types: deciduous (orange), mixed (blue), or evergreen (green; n = 27, 13, and 7 biologically independent populations respectively). Phenological sensitivity is higher in deciduous habitats than either evergreen or mixed habitats. Shown are box and violin plots of phenological sensitivity of both great and blue tits in each habitat type. Boxplots shows median (centre line), 25th and 75th quantiles (lower and upper hinges), and 1.5× inter-quartile range (whiskers). Observations further than 1.5× inter-quartile range are shown as outlier points.
