White Spruce Photosynthetic and Leaf Traits, Alaska & New York, 2017
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.
