In addition to PAR and UV point measurements, total light intensity was monitored under three UV-filtering and UV-transmitting window pairs every 30 minutes for four months from February 2019 until three days before sample collection in June 2019 with Onset HOBO Pendant Temperature/Light (relative light intensity from 0 – 320,000 lux) Logger (UA-002, Onset Computer Corporation, Bourne, MA, USA). Data were summarized to mean daily highs and lows per month for each treatment per microsite pair. Mean daily highs and lows per month were tested for treatment effects with a one-way repeated measures ANOVA for each pair.
