Research Interests: 

Professor Hart's research explores the controls of biogeochemical processes and productivity in managed and wildland terrestrial ecosystems using methods such as:

  • Ecological genetics to isotopic analyses
  • Computer simulation modeling
  • Elucidate the biotic and abiotic factors that regulate terrestrial ecosystem structure and function

His research group is currently investigating:

  • Biological and geochemical controls on ecosystem development along a three million year, semi-arid soil chronosequence
  • Influence of the genetics of dominant plants on ecosystem processes
  • Effects of forest restoration treatments (e.g., thinning with or without prescribed fire) and wildfire on ecosystem carbon and water balance, soil microbial communities, and belowground processes
  • Efficacy of insect communities as indicators of forest ecosystem health
  • Utility of the 15N natural abundance signature of soil microbes as an integrator of nitrogen cycling processes
  • Impact of climatic change on soil-plant-atmosphere interactions; and the effects of water diversion on riparian forest
