Research Interests
Dr. Link's research interests lie in the general area of ecophysiology for both higher and lower plants. Research on lichens has included photosynthetic measurements and modeling of gas exchange for the prediction of carbon gain by lichens in the field. Research with vascular plants has included measurement and modeling of whole-plant photosynthetic and transpiration for rangeland shrubs and grasses. Current projects include research on stem strain gauges to monitor the effect of stress on plant function, the effect of nitrogen and water on carbon, water, and nitrogen cycling in arid ecosystems, water relations of arid land plants, the role of plants on landfill cover caps, remote sensing of arid environments, measurement of biogenic gases, and the ecophysiology of desert cryptogamic crusts.
