Combined Effects of Intensive Forest Management and Microclimate on Reproduction in a Cavity-Nesting Songbird

Creator:: Jones, Kristin N.
Abstract:: Future scenarios of global climate change rely on large-scale climate envelope models that do not account for local climatic conditions to which organisms most closely respond. Shifts in species distributions and phenology driven by climate change are well-documented, yet we lack a strong understanding of how climate change will influence...

Biodiversity Responses in Early Seral Forests of the Klamath-Siskiyou: Comparisons with Birds, Bees, and Ground Beetles among Post-fire, Salvage Logging, and Intensive Forest Management Environments

Creator:: Frank, Graham S.
Abstract:: Early seral forests regenerating from stand-replacing disturbances provide unique habitat for many species in productive, temperate forest landscapes and contribute to supporting biodiversity. Population declines in some species associated with early seral forests have prompted concerns about the conservation of these habitats, particularly the characteristic structural and compositional complexity associated...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

Contrasting Hydraulic Strategies in Two Tropical Lianas and Their Host Trees

Creator:: Johnson, Daniel M., Domec, Jean-Christophe, Woodruff, David R., McCulloh, Katherine A., and Meinzer, Frederick C.
Abstract:: • Premise of the Study: Tropical liana abundance has been increasing over the past 40 yr, which has been associated with reduced rainfall. The proposed mechanism allowing lianas to thrive in dry conditions is deeper root systems than co-occurring trees, although we know very little about the fundamental hydraulic physiology...

Making Sense of the Wilderness Experience in the United States: A Multidisciplinary Approach

Creator:: Engebretson, Jesse M.
Abstract:: Federally designated wilderness areas in the United States are uniquely required to provide opportunities for particular types of recreational experiences. According to the Wilderness Act of 1964, the law that governs the management of designated wilderness in the U.S., wilderness areas are to provide “outstanding opportunities for solitude or a...

Above- and belowground controls on water use by trees of different wood types in an eastern US deciduous forest

Creator:: Meinzer, Frederick C., Woodruff, David R., Eissenstat, David M., Lin, Henry S., Adams, Thomas S., and McCulloh, Katherine A.
Abstract:: Stomata control tree transpiration by sensing and integrating environmental signals originating in the atmosphere and soil, and co-occurring species may differ in inherent stomatal sensitivity to these above- and belowground signals and in the types of signals to which they respond. Stomatal responsiveness to environmental signals is likely to differ...

The Role of Facilitation for Maintaining Key Processes of Sagebrush-steppe Plant Populations in a Changing Climate

Creator:: Weisgerber, Elizabeth K.
Abstract:: Drought events have been shown to impact species distributions and are predicted to increase in frequency as the climate changes. As this occurs, ecologists predict species distributions will shift dependent upon species ability to track climate. These shifts in species distribution are expected to be particularly acute in arid and...

Impacts of dwarf mistletoe on the physiology of host Tsuga heterophylla trees as recorded in tree ring C and O stable isotopes

Creator:: Marias, Danielle E.
Abstract:: Dwarf mistletoes, obligate, parasitic plants with diminutive aerial shoots, have long-term effects on host tree water relations, hydraulic architecture, and photosynthetic gas exchange and can eventually lead to tree death. To investigate the long-term impacts of dwarf mistletoe on gas exchange of host western hemlock trees, I compared growth, gas...

Plants and their Environment: Assessing Canopy Microclimate and the Response of Trees to Environmental Stress in a Diversity of Forest Types

Creator:: Sibley, Adam M.
Abstract:: The topics in this dissertation are centered around the way that trees respond to environmental stress in the climates where they occur. Though forests across the planet are expected to experience change in local climate due to historic and ongoing anthropogenic greenhouse gas emissions, the effects of climate change will...

Do Ray Cells Provide a Pathway for Radial Water Movement in the Stems of Conifer Trees?

Creator:: Barnard, David M., Lachenbruch, Barbara, McCulloh, Katherine A., Kitin, Peter, and Meinzer, Frederick C.
Abstract:: • Premise of the study: The pathway of radial water movement in tree stems presents an unknown with respect to whole-tree hydraulics. Radial profi les have shown substantial axial sap fl ow in deeper layers of sapwood (that may lack direct connection to transpiring leaves), which suggests the existence of...
