Table 4. Mixed effect models conducted on theg1 estimates. Square root transformation was
applied to meet ANOVA assumptions. Campaign representing day of
measurement was used as random variable. Experimental factors are
represented as follow: sites (Cloquet Forestry Center – in Cloquet, MN
and Hubachek Wilderness Research Center – Ely, MN), warming (ambient T
and +3.3°C), reduced rainfall (ambient and ~40% of
summer rainfall removed), species (see Table 3). The environmental
treatment (i.e., open and closed canopy) are analyzed separately.
