Research Interests:
Mineral nutrition and cold tolerance of tree seedlings.

My research interests are in the field of tree seedling physiology. I am particularly interested in how temperate and boreal trees adapt and acclimate to the stresses of low temperature and low levels of available nitrogen. To distinguish between adaptation and acclimation, I explore the interaction of genetic and environmental components of seedling response to nutrient stress and cold stress.
Recent projects in my lab include:

  • Studies of net fluxes of ammonium, nitrate and protons along the length of conifer seedling roots; and how these fluxes are affected by species, genotype, nutrient status of the plant, and pH and nutrient concentration of the root medium.
  • Measurement of net fluxes of ammonium, nitrate and protons in the pitchers of several species of pitcher plants
  • Measurements of available ammonium, nitrate and amino acids in forest soils and uptake of these inorganic and organic forms of nitrogen by forest trees and shrubs
  • Assessment of the phenology and cold hardiness of full-sib families from the coastal Douglas-fir tree improvement program.
