Nitrogen and phosphorus dynamics during decomposition of multiple litter types in temperate coniferous forests

Creator:

van Huysen, Tiffany L.

Abstract:

Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...

Non-linear nitrogen dynamics and calcium depletion along a temperate forest soil nitrogen gradient

Creator:

Sinkhorn, Emily R.

Abstract:

Understanding how N availability influences base cation stores is critical for long-term ecosystem sustainability. Indices of nitrogen (N) availability and the distribution of nutrients in plant biomass, soil, and soil water were examined across ten young, unpolluted Douglas-fir (Pseudotsuga menziesii) stands in the Oregon Coast Range spanning a three-fold soil...
