PAR and UV-A/B radiation (250 – 400 nm) were measured under windows and at nearby unmanipulated site reference mosses in April 2019 using LightScout UV and Quantum Sensors and the LightScout Sensor Reader (Spectrum Technologies, Aurora, IL, USA). Light under each pair of windows were measured at the same time, though measurements of all pairs were completed over the course of two hours. Data were first tested for normality with the Shapiro-Wilk test (Shapiro and Wilk, 1965). Differences in PAR between field treatments were tested for with two-tailed paired Student’s T-tests and differences in UV were tested for with Wilcoxon signed-rank tests (Wilcoxon, 1945). Significance was adjusted with the Benjamini and Hochberg (BH) correction (Benjamini and Hochberg, 1995) to account for the false discovery rate of multiple tests (Jafari and Ansari-Pour, 2019).
