Light Measurements
PAR and UV-A/B radiation (250 – 400 nm) were measured under windows and at nearby un-manipulated site reference mosses in April 2019 using LightScout UV and Quantum Sensors and the LightScout Sensor Reader (Spectrum Technologies, Aurora, IL, USA). Data were first tested for normality with the Shapiro-Wilk test (Shapiro & 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 correction (Benjamini & Hochberg 1995) to account for the false discovery rate of multiple tests (Jafari & Ansari-Pour 2019).
