A systematic review evaluates how artificial lighting affects lizard behavior and physiology, indicating significant impacts on ecosystems.
Artificial Light at Night (ALAN) is an increasingly pervasive environmental pollutant that disrupts natural photoperiods and alters biological rhythms. While its effects have been widely studied across taxa, a quantitative synthesis focused on lizards remains lacking. This study addresses this gap through a systematic review and meta-analysis evaluating the impact of ALAN on lizard behavior and physiology. Using PRISMA 2020 guidelines, we compiled data from 20 empirical studies and conducted a random-effects meta-analysis using Hedges’ g. The overall analysis revealed a significant positive effect of ALAN on lizard activity and physiological responses (g = 0.6787, 95% CI [0.4400, 0.9174], p < 0.0001). Invasion status emerged as a significant moderator, with invasive species showing approximately 2.2× stronger responses than native species. These findings suggest that artificial lighting creates a "night-light niche" that disproportionately benefits invasive species and reshapes urban ecological dynamics.
