Foraging Niche Separation of Adélie (Pygoscelis adeliae) and Gentoo (P. papua) Penguins During the Breeding Season at Palmer Station, Antarctica

Creator:: Pickett, Erin
Abstract:: Climate-induced range overlap can result in novel interactions between similar species and potentially lead to competitive exclusion. The Western Antarctic Peninsula is one of the most rapidly warming regions on Earth and is experiencing a poleward climate migration. This transition from a polar to sub-polar environment has resulted in a...

Designing Dielectric Materials through Complex Metal Oxides

Creator:: Nikkel, Jason W.
Abstract:: This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...

Recovery of High-graded Nothofagus Forests: Building Resilience Through Theory and Practice

Creator:: Soto, Daniel P.
Abstract:: The increasing human demands on natural resources, in combination with uncertainties about ecosystem dynamics due to global change, has led the scientific community to conclude that new approaches in understanding of ecological systems are needed to tackle environmental issues in an efficient manner. One development that has received more attention...

Generalized linear mixed models with censored covariates

Creator:: Giovanini, John
Abstract:: This dissertation is about statistical methods for data analysis using generalized linear mixed models (GLMMs) with censored covariates. Special attention in given to the particular problem of inference about age-specific reproductive success in wild animal populations using some animals with known ages and some animals with ages only known to...

Seismotectonics of the Himalayas and the Tibetan Plateau : moment tensoranalysis of regional seismograms

Creator:: Baur, Jan R.
Abstract:: This thesis presents a detailed seismotectonic investigation of the Himalayan region and the Tibetan plateau as part of project HiCLIMB to explore the state of stress and the kinematics of the world’s largest continental collision zone. Using full regional waveforms for moment tensor inversion, source parameters for 107 earthquakes were...

Age-specific and lifetime reproductive success of known age Northern Spotted Owls on four study areas in Oregon and Washington

Creator:: Loschl, Peter J.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) are a long-lived forest owl and range-wide declines in their numbers have resulted in the species being listed as threatened under the endangered species act. While many studies have been focused on population trends and reproductive performance of Spotted Owls from different age-classes, none...

Spectral Analysis of Upper Ocean Surface Wave Structure using χSOLO Floats in the Bay of Bengal

Creator:: Ball, Matthew S.
Abstract:: Surface waves play a vital role in air-sea interactions, and being able to easily measure them in-situ validates and improves predictive models. Here, we diagnose surface wave properties in the Bay of Bengal using modified vertical SOLO II profiling floats, which are regularly used as part of the Argo ocean...

Normal acceleration characteristics of the leading vehicle in a queue at signalized intersections on arterial streets

Creator:: Zhu, Hong
Abstract:: Normal acceleration characteristics of passenger cars provide valuable information for various aspects of transportation engineering, including use in the geometric designs of intersections, freeway ramps, passing lanes, acceleration lanes, turning bays, or in the development of traffic simulation or fuel consumption models. However, the data used in previous studies are...

Functional groups, traits, and the performance of species in restoration

Creator:: Roberts, Rachael E. (Rachael Elaine)
Abstract:: In ecological restoration, species that are sown to increase the native plant diversity range in establishment ability. Some species readily establish, while others rarely do. This study set out to investigate some of the potential processes influencing species establishment, as well as the traits that are associated with the success...

Southern Ocean Science and Society: Case Studies at the Nexus of Research, Education, and Policy

Creator:: Hann, Ashley M.
Abstract:: Even in remote environments, human and natural systems are connected. Pressing environmental and social changes warrant the field of science to not only continue to enhance understanding of the natural world, but also consider the socio-ecological implications of research in the coupled human-natural system. Additionally, a need exists for communication...
