The Discourse of Demographic Diversity in U.S. Natural Resources Scholarly Literature: A Multi-Methods Qualitative Study

Creator:: Brown, Jasmine K.
Abstract:: Racial, ethnic and gender diversity have been long term topics of discussion in natural resources. Yet to date, there has not been a comprehensive review of the existing literature within the discourse of demographic diversity. Therefore, I conducted a systematic review of demographic diversity in the disciplines of forestry, fisheries,...

An individual-based process model to simulate landscape-scale forest ecosystem dynamics

Creator:: Seidl, Rupert, Rammer, Werner, Scheller, Robert M., and Spies, Thomas A.
Abstract:: Forest ecosystem dynamics emerges from nonlinear interactions between adaptive biotic agents (i.e., individual trees) and their relationship with a spatially and temporally heterogeneous abiotic environment. Understanding and predicting the dynamics resulting from these complex interactions is crucial for the sustainable stewardship of ecosystems, particularly in the context of rapidly changing...

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...

Estimating heterotrophic respiration at large scales: challenges, approaches, and next steps

Creator:: Bond-Lamberty, Ben, Epron, Daniel, Harden, Jennifer, Harmon, Mark E., Hoffman, Forrest, Kumar, Jitendra, David McGuire, Anthony, and Vargas, Rodrigo
Abstract:: Heterotrophic respiration (HR), the aerobic and anaerobic processes mineralizing organic matter, is a key carbon flux but one impossible to measure at scales significantly larger than small experimental plots. This impedes our ability to understand carbon and nutrient cycles, benchmark models, or reliably upscale point measurements. Given that a new...

Differences in Evolutionary History and Ploidy Type Shape the Interactions of Populus tremuloides Michx. with Climate

Creator:: Greer, Burke Thomas
Abstract:: Quaking aspen (Populus tremuloides Michx) is a species with high phenotypic plasticity and a broad distribution that, in the last decade, has experienced climate stress-induced mortality called Sudden Aspen Decline (SAD). In order to help mitigate the effects of SAD in the future, we need a better understanding of aspen’s...

The effects of mechanical damage on residual coastal Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) following commercial thinning

Creator:: Kiser, James D.
Abstract:: Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...

Analysis of the regional carbon balance of Pacific Northwest forests under changing climate, disturbance, and management for bioenergy

Creator:: Hudiburg, Tara W.
Abstract:: Atmospheric carbon dioxide levels have been steadily increasing from anthropogenic energy production, development and use. Carbon cycling in the terrestrial biosphere, particularly forest ecosystems, has an important role in regulating atmospheric concentrations of carbon dioxide. US West coast forest management policies are being developed to implement forest bioenergy production while...

Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

Creator:: Gonçalves, Fabio Guimarães
Abstract:: Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Mixed-conifer forests of central Oregon : structure, composition, history of establishment, and growth

Creator:: Merschel, Andrew G.
Abstract:: The structure and composition of mixed-conifer forest (MCF) in central Oregon has been altered by fire exclusion and logging. The resulting increased density, spatial contagion, and loss of fire resistant trees decrease the resiliency of this ecosystem to fire, drought, and insects. The historical and current composition and structure of...
