Microclimate
In order to understand the effects of the window treatments on the microclimate, data loggers were deployed under three pairs of windows and at nearby soil-surface mosses. These windows were installed specifically for this purpose and moss samples were not collected from them. To log temperature and relative humidity (RH) every five minutes, iButton hygrochrons (Maxim Integrated, San Jose, CA, USA) were deployed in winter (February) and summer (September) 2019 for a period of four and two days, respectively. In addition to the three pairs, in September iButton hygrochrons were used to measure temperature and RH of a nearby (within 1 m of windows) un-manipulated site reference moss cushion.
Temperature and RH data were summarized to mean daily high and low per site per treatment (UV-filtered, UV-transmitted, plus site reference for September), tested for normality with the Shapiro-Wilk test (Shapiro & Wilk 1965), and subsequently tested for significance of treatment effect with one ANOVA for each data set (summer and winter). Significance was adjusted with the Benjamini and Hochberg method (Benjamini & Hochberg 1995).
