Ratios of (a) maximum rate of carboxylation to respiration at 25 degrees C from Griffin et al. (2022) (Vcmax /R25 ) and (b) maximum electron transport rate to respiration at 25 degrees C from Griffin et al. (2022) (Jmax /R25 ) of white spruce from high and low canopy positions at the Forest Tundra Ecotone (FTE, blue), Alaska, and Black Rock Forest (BRF, green), New York. Boxplots show the median and first and third quartiles. Whiskers display the range of groups with individual points representing outliers falling outside 1.5 times the interquartile range. Different letters represent significant differences between locations and canopy positions.

 

Body
Measurements of gas exchange, leaf traits, leaf pigments, the photochemical reflectance index, and average photosynthetic photon flux density from hemispherical photographs.
