Determine how carbon relations (photosynthesis, respiration) and underlying processes such as stomatal limitations and water relations differ among subspecies and provenances of big sagebrush. These will be evaluated in response to temporal variation in temperature and water availability and in reponse to geographic variation for common gardens established in climatically differing areas. A secondary objective is to relate these ecophysiological insights to USFS measurements of whole-plant growth and molecular genotyping and transcriptome information.
