Dead wood dynamics and relationships to biophysical factors, forest history, ownership, and management practices in the Coastal Province of Oregon, USA

Creator:: Kennedy, Rebecca S.H.
Abstract:: Dead wood patterns and dynamics vary with biophysical factors, disturbance history, ownership, and management practices. Through field and modeling studies, I examined the current and potential future amounts of dead wood in two landscapes and region-wide in the Coastal Province of Oregon. The objectives of the first study were to...

Community gradients of Arctic macrolichens in relation to succession, grazing and the environment

Creator:: Holt, Emily A.
Abstract:: The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

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...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Sensitivity of Forest Structure Estimation to UAS-Based Data Processing Algorithms

Creator:: Maturbongs, Bonifasius Y. L
Abstract:: Forests should be monitored and measured frequently to ensure its sustainability and continuity of carbon sequestration. However, conventional monitoring methods are costly and labor intensive. New technologies, such as unmanned aircraft systems (UAS) can be used as an alternative method to monitor and measure forests. The objective of this study...

Landsat-based monitoring of annual wetland change in the main-stem Willamette River floodplain of Oregon, USA from 1972 to 2012

Creator:: Fickas, Kate C.
Abstract:: Despite holding substantial ecological value, wetlands in the United States have experienced a significant decline in both area and function over the past century with the majority of freshwater wetland loss attributed to agricultural conversion. Agriculture is the second largest industry in the State of Oregon and the State places...

Grazer-resource Behavior, Interactions, and Feedbacks Control Kelp-forest Dynamics and Stability

Creator:: Randell, Zachary H.
Abstract:: How the direct and indirect effects of species interactions cascade to affect community structure, functioning, and stability is a fundamental question in ecology. In temperate kelp forests, species interactions, in conjunction with environmental processes, produce rich spatiotemporal dynamics. Arguably the most dramatic of these are abrupt shifts in community state,...

Forest Succession and Climate Change Effects on Long-Term Runoff Coefficients at Varying Timescales

Creator:: Crampe, Emily A.
Abstract:: Forest harvesting and climate change induced shifts in precipitation characteristics (i.e., intensity, type) may affect how water is partitioned on the landscape, with more water potentially being lost to evaporation or groundwater, and less water being partitioned into the stream. Long-term, paired watershed data allows us to assess these possible...

Assessment of the Vegetation Changes using High-Resolution 4-Band Imagery

Creator:: Galapita Pallayapelage, Sudeera Wickramarathna
Abstract:: Natural resources are essential to humanity. With the increase in global development in recent decades, people must monitor the state of the environment, whose disturbance has a more significant impact on society than before. However, conventional environmental monitoring is challenged in highly dynamic ecosystems and large areas. As a solution,...
