Spatial and temporal effects of atmospheric deposition, climate, and land management on forest nutrient cycling and biodiversity

Creator:

McDonnell, Todd C.

Abstract:

Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...

Diversity and abundance of birds across a hardwood gradient in early seral Douglas-fir plantations

Creator:

Ellis, Tana M.

Abstract:

Recent evidence suggests that population declines of some avian species may be driven primarily by reduced quantity and diversity of early-successional habitat on the breeding grounds. Increasing intensity of forest management on private lands and decreased harvest rates on federal lands has resulted in a loss of the diverse early-successional...

Past climate variability in southwestern Oregon and relationships with regional and hemispheric climate

Creator:

Ersek, Vasile

Abstract:

This dissertation presents the results of three studies that assessed climate variability on short and long timescales in western United States. The growth of carbonate formations in caves (speleothems) is used to infer the timing and amplitude of past climate variability. We first assess the controls on speleothem growth for...
