Ecophysiology and Adaptation in Desert Shrubs: Final Report

摘要

During the current funding period, we have focused on two main areas: (1) a consideration of the water sources used by plants, (2) a consideration of the role, extent and significance of twig photosynthesis in aridland species, and (3) studies of variation in carbon isotopic composition in plants as an indicator of water-use efficiency (ratio of photosynthesis to transpiration). Although not specifically a research project, a substantial amount of time was also spent organizing and editing ''Stable Isotopes in Ecological Research,'' which was the result of a very successful, DOE-OHER sponsored symposium bringing together terrestrial and marine ecologists to discuss this topic for the first time. 14 refs., 6 figs., 2 tabs.
