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).
