Temperature 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 monthly mean daily highs and lows for each treatment and site and to pooled means across all sites. Mean daily highs and lows for each treatment per site per month were tested for significance of treatment effect with a one-way repeated measures ANOVA.
