My Published Research

You may deem this as research vetted by the peer-review process, for what value that adds.

My research has had good exposure, being published in 23 different international journals, book chapters, and a monograph, in chemistry, physics, plant physiology, ecology, global change, agronomy, remote sensing, and other fields (evidence of a poor attention span for a given discipline?).  Still, there are findings that I wish to have more utility in research and in applications.  One example with practical and policy implications is my the  formulation that my wife, Dr. Lou Ellen Kay, and I developed of functional balance in plants’ nutrient acquisition and nutrient use (for photosynthesis), particularly as it offers a physiological framework for understanding the drop in tissue N content at elevated CO2.  The common explanation for the drop is dilution by high carbohydate accumulation, which is not so useful.  I’ve elaborated more on high-CO2 effects, projecting diversity in plant responses in tissue N content, N-use efficiency, water-use efficiency, and growth rate.  In climate-change research, many models of diverse (or, alternatively, in-common) responses of plants focus on temperature and precipitation changes, omitting the direct physiological responses to CO2.  Another example is my finding, on the modeling side of a modeling-experiment study, that pecan trees apparently lack a water-sparing response to low relative humidity.  This has implications for irrigation water use, orchard siting, and other policies.

These under-utilized ideas will be populated on this page.  In this effort, especially, I will welcome comments and collaborations.  I am still setting up the structure of comment handling at this time.
