Linkages between mangrove forests and coral reefs : quantifying disturbance effects and energy flow between systems

Creator:: Granek, Elise F.
Abstract:: Interface habitats are considered valuable natural systems, tightly linked to adjacent habitats through the flow of matter and energy. However, there is limited research on mechanisms of connectivity such as movement of organisms and particulate matter and ways in which anthropogenic disturbance to interface habitats may affect immediate and adjacent...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

A summative evaluation of a dolphin assisted therapy program for children with special needs

Creator:: Dilts, Rachel M.
Abstract:: This dissertation reviews the literature on the specialty area of dolphin assisted therapy (DAT), a subfield of animal assisted therapy (AAT). To date the literature on the effectiveness of DAT has been mixed although a majority of it is positive. The study was conducted with 40 parents whose children were...

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 ecology of wild turkey (Meleagris gallopavo) foraging in Pacific Northwest ecosystems

Creator:: Evans-Peters, Sara Tondee
Abstract:: Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...

Physical Modeling of the Feedbacks Between a Reed Canarygrass (Phalaris arundinacea) Patch, Hydraulics, and Bedform Evolution

Creator:: Elliott, Susan H.
Abstract:: Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...

New insights into the biology of theropod dinosaurs

Creator:: Quick, Devon E.
Abstract:: There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and...

Relations between Physical Fitness and School-Day Physical Activity Behavior in Children with Autism Spectrum Disorder

Creator:: Tyler, Kiley J.
Abstract:: Background. Autism spectrum disorder (ASD) is characterized by impairments in social-communicative deficits and restricted and repetitive behaviors, interests, or activities (APA, 2013). While current estimates suggest 1 in 68 children are diagnosed with ASD, more alarming statistics indicate 1 in 50 school-aged children live with the disorder (Blumberg, Bramlett, Kogan,...

Functional Diversity : A Tool to Track Spatiotemporal Changes in the Trophic Organization of Reef Fish Assemblages

Creator:: Rincón Diaz, Martha P.
Abstract:: Biodiversity loss in highly diverse systems such as coral reefs has been linked to significant declines in the ecosystem functions and services provided by marine species. Ecological functioning of coral reefs and the resistance of coral reef fish communities to disturbance depend on the functional traits of species that promotes...

Using Recession Analysis to Characterize Watershed Responses to Drought

Creator:: Jachens, Elizabeth R.
Abstract:: In the face of climate change droughts are predicted to become more persistent, further intensifying the need for accurately predicting the timing and magnitude of summer streamflow in rivers. In order to determine the sensitivity of a watershed to drought, there is a need to describe what these drought conditions...
