How does foliar thermotolerance vary by:
-leaf age? -species? -within-species populations from contrasting climates? We ask these types of questions to understand how agricultural (Coffea arabica) and forest (Pinus ponderosa, Pseudotsuga menziesii, Pinus edulis, Juniperus monosperma, Pinus albicaulis) species will respond to warmer temperatures. We measure thermotolerance curves using 2 independent methods: chlorophyll fluorescence and electrolyte leakage. Marias et al. (2016) Trees Marias et al. (2016) Tree Physiology |
