Research Interests and Activities:
Linda H. Pardo has worked at the Hubbard Brook Experimental Forest since 1989. Her research interests include nutrient cycling, especially nitrogen cycling, and biogeochemistry of light stable isotopes. Current projects include: (1) Relating soil physical properties including particle size distribution to soil functional characteristics (including soil moisture and N cycling) in the context of the hydropedology of W3, (2) Evaluating the factors that control tree species differences in tissue d 15N, (3) Incorporating interactions with climate change into empirical critical loads of N deposition
