Linking marine communities and ecosystems : invertebrates mediate nutrient availability in intertidal communities

Creator:: Bracken, Matthew E.
Abstract:: While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

Tradeoffs and Synergies among Wild Ungulates, Early Successional Plant Communities and Management Intensification in Forest Plantations of the Oregon Coast Range

Creator:: Stokely, Thomas D.
Abstract:: As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...

Individual Host to Population Scale Dynamics of Parasite Assemblages in African Buffalo of Kruger National Park, South Africa

Creator:: Glidden, Caroline K.
Abstract:: The last century has experienced a marked increase in emerging infectious disease (EID, hereafter) – jeopardizing human, domestic animal, and wildlife health. EIDs are commonly associated with spillover from one host species into a novel host species, with many destructive diseases, for both livestock and wildlife, emerging at the wildlife-livestock...

Algal community structure and organization in high intertidal rockpools

Creator:: van Tamelen, Peter G.
Abstract:: Gradients of physical disturbance are central to theories of community organization yet rarely are studies performed in which physical factors are experimentally manipulated. Pothole tidepool algal communities exhibit distinct zonation patterns from top to bottom that result from scouring by rocks and other debris in the pools. Scouring is easily...

Effects of environmental stress on intertidal mussel reproduction

Creator:: Petes, Laura E.
Abstract:: Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

Strategies to Improve Density and Moisture Resistance of Asphalt Mixtures in Oregon

Creator:: Kumar, Vikas
Abstract:: Asphalt pavements constitute more than ninety percent of the nation’s roadway network. Besides serving the key role of providing a smooth and durable all-weather surface that benefits a range of users, they are also the lifelines of the nation and the world and contribute tremendously towards economic and social development....

Three-dimensional motion of the center of mass and energetic cost across a variety of walking speeds : a comparison between adults with and without Down syndrome

Creator:: Agiovlasitis, Stamatis
Abstract:: It has been previously suggested that the walking pattern of individuals with Down syndrome is inefficient. This is thought to result from increased instability, particularly in the medio-lateral direction, due to the characteristic joint laxity and muscle hypotonia of individuals with DS. Therefore, this work was an attempt to gain...

Indirect effects of fishing on predators and their prey

Creator:: Stallings, Christopher Derek
Abstract:: Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...
