Fall directions and breakage of riparian trees along streams in the Pacific Northwest

Creator:

Sobota, Daniel J.

Abstract:

In the Pacific Northwest, regulatory agencies have recently implemented management strategies for restoration and maintenance of wood recruitment to streams over time. This allochthonous organic material is a critical component in the geomorphic and biological structure of forested streams. Mathematical models are commonly used to evaluate long-term wood dynamics in...

Linkages among land use, riparian zones, and uptake and transformation of nitrate in stream ecosystems

Creator:

Sobota, Daniel J.

Abstract:

Land use alters the physical and biological structure of stream ecosystems and potentially alters their capacity to process nitrogen (N), an essential nutrient that has nearly doubled in abundance on the biosphere during the past century from human activities. In this dissertation, I quantified uptake and transformation of nitrate (NO₃⁻)...
