  • Tree species-soils relationships in old-growth forests of the Oregon Coast Range

    Creator:
    Cross, Alison
    Abstract:
    Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and bigleaf maple) in mixed-species old-growth forests of the Oregon Coast Range and to determine whether and how soils differ among the...

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

    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...
