Ecophysiology and Adaptation in Desert Shrubs

摘要

The carbon isotope ratios of nineteen warm desert shrub species were sampled monthly. Precise estimates of the water-use efficiency patterns of the species change through time were made. How carbon isotope ratios (measures of integrated water-use efficiency) change with respect to microhabitat (wash, slope and transition zone) were measured with respect to the relative distributions of species along this cline.
