Extended Data Fig. 6: Balanced dataset GAMM predictions of half-hourly and daily carbon flux responses to ALAN and night duration.
From: Widespread influence of artificial light at night on ecosystem metabolism
Variance-weighted GAMMs were fitted to the balanced ALAN intensity dataset, comprising an equal number of sites (n = 4 each in low, medium, and high ALAN intensity categories per continent). Panels (a–c) show predicted relative changes in half-hourly (a-c) and mean daily (d-f) carbon fluxes for NEE (a, d), GPP (b, e), Re (c, f) as a function of ALAN (DN) intensity. Coloured lines represent night duration (ND) categories of 9, 12, and 15 h, with shaded ribbons representing mean predictions ±95% confidence intervals. The horizontal dashed line denotes zero relative change.
