Ecohydrological mediation of water budget partitioning and time scales of subsurface flow in a seasonally semi-arid grassland

Creator:

Pangle, Luke A.

Abstract:

Understanding how the interactions and feedbacks between plant function, climate, and soils ultimately affects the terrestrial water balance and subsurface flow processes is major challenge in scientific hydrology. This dissertation summarizes the findings of a manipulative climate warming experiment, an observational field study that utilized stable-isotope tracers, and associated modeling...

The effects of water and shade treatments on photosynthesis and root-rhizosphere respiration in young ponderosa pine

Creator:

Johnson, Theresa J.

Abstract:

Water treatments were applied to young ponderosa pine trees in the Eastern Cascades, Oregon during the 2003 growing season, and shade treatments were applied during the 2003 and 2004 growing seasons to understand how photosynthesis and soil respiration, particularly the root/rhizosphere fraction (R[subscript rrh]), would respond to increased moisture availability...

Height-related trends in structure and function of Douglas-fir foliage

Creator:

Woodruff, David R.

Abstract:

This dissertation investigated the impacts of tree height upon a range of physiological and structural characteristics of Douglas-fir foliage; relationships between structural and functional trends with height; and compensatory mechanisms that mitigate height-related growth constraints. Height-related trends in foliar physiological and anatomical characteristics were examined both within trees as well...
