The Spread Of Exotic Plant Species At Mount St. Helens: The Roles Of A Road, Disturbance Type And Post-Disturbance Management, Lindsey Karr Jan 2014

The Spread Of Exotic Plant Species At Mount St. Helens: The Roles Of A Road, Disturbance Type And Post-Disturbance Management, Lindsey Karr

Environmental Science and Management Professional Master's Project Reports

The landscape of Mount St Helens was dramatically transformed when it erupted on May 18, 1980, creating an outstanding opportunity for ecologists to study succession following a large, intense, natural disturbance. Within the expansive (600 km2) blast area there is varied ownership and a mix of management objectives for the post-eruption landscape. On lands administered by the U.S. Forest Service, there are portions of the blast area that have been designated as a National Volcanic Monument, where the primary management objective is to allow for natural succession to proceed substantially unimpeded. In other areas outside the Monument, salvage …

Plant Response To 14 Engineered Log Jams On The North Fork Toutle River, Wa Sediment Plain, Todd Ashley Jan 2014

Plant Response To 14 Engineered Log Jams On The North Fork Toutle River, Wa Sediment Plain, Todd Ashley

Environmental Science and Management Professional Master's Project Reports

I sought to evaluate the vegetative response to the installation of the 14 engineered log jams (ELJs) on the North Fork Toutle River (NFTR) Sediment Plain. The NFTR sediment plain is constantly being reworked due to channel bank erosion caused by a combination of processes including flow erosion and gravitational mass failure. Vegetation has the ability to protect the bank from erosion as well as providing other stabilizing effects. The ELJ structures were designed in part to protect localized areas of the sediment plain and allow vegetated islands to develop. The purpose of these vegetated islands is to trap sand …

Environmental Science and Management Faculty Publications and Presentations

The effects of forest management on soil carbon (C) and nitrogen (N) dynamics vary by harvest type and species. We simulated long-term effects of bole-only harvesting of aspen (Populus tremuloides) on stand productivity and interaction of CN cycles with a multiple model approach. Five models, Biome-BGC, CENTURY, FORECAST, LANDIS-II with Century-based soil dynamics, and PnET-CN, were run for 350 years with seven harvesting events on nutrient-poor, sandy soils representing northwestern Wisconsin, USA. Twenty CN state and flux variables were summarized from the models' outputs, and statistically analyzed using ordination and variance analysis methods. The multiple models' averages suggest that bole-only …

Getting Plant Conservation Right (Or Not): The Case Of The United States, Kayri Havens, Andrea T. Kramer, Edward O. Guerrant Jr. Jan 2014

Getting Plant Conservation Right (Or Not): The Case Of The United States, Kayri Havens, Andrea T. Kramer, Edward O. Guerrant Jr.

Environmental Science and Management Faculty Publications and Presentations

Effective plant conservation includes addressing basic needs such as information about species distribution and rarity; research, management, education, and training capacity to mitigate threats facing threatened species; policy and funding to support continued capacity and conservation; and, ultimately, a public that understands and supports the importance of plants and the need for their conservation. Coordination of plant conservation efforts is also needed to ensure that resources and expertise are used in a strategic, efficient, and effective manner.We argue that no country is currently getting plant conservation right; plants are becoming increasingly rare around the world. Plants are often not fully …

Sampling For Effective Ex Situ Plant Conservation, Edward O. Guerrant Jr., Kayri Havens, Pati Vitt Jan 2014

Sampling For Effective Ex Situ Plant Conservation, Edward O. Guerrant Jr., Kayri Havens, Pati Vitt

Environmental Science and Management Faculty Publications and Presentations

Sampling a whole flora or any significant subset for ex situ conservation purposes is a complex, long-term proposition. Thus, it is important to consider what constitutes an adequate sample not only for all taxa as a whole but also for each taxon individually as well as how to strategically schedule collection over time. There are five basic sampling questions: from which species to collect, from how many and which populations, from how many and which individuals, how many and what kind of propagules to collect, and, finally, at what point is the desired sample size too great for a population …

Impacts Of Fire And Climate Change On Long-Term Nitrogen Availability And Forest Productivity In The New Jersey Pine Barrens, Melissa S. Lucash, Robert M. Scheller, Alec M. Kretchun, Kenneth L. Clark, John Hom Jan 2014

Impacts Of Fire And Climate Change On Long-Term Nitrogen Availability And Forest Productivity In The New Jersey Pine Barrens, Melissa S. Lucash, Robert M. Scheller, Alec M. Kretchun, Kenneth L. Clark, John Hom

Environmental Science and Management Faculty Publications and Presentations

Increased wildfires and temperatures due to climate change are expected to have profound effects on forest productivity and nitrogen (N) cycling. Forecasts about how wildfire and climate change will affect forests seldom consider N availability, which may limit forest response to climate change, particularly in fire-prone landscapes. The overall objective of this study was to examine how wildfire and climate change affect long-term mineral N availability in a fire-prone landscape. We employed a commonly used landscape simulation model (LANDIS-II) in the New Jersey Pine Barrens, a landscape characterized by frequent small fires and fire-resilient vegetation. We found that fire had …

Small Tidal Channels Improve Foraging Opportunities For Calidris Shorebirds, Aileen K. Miller, Catherine E. De Rivera Jan 2014

Small Tidal Channels Improve Foraging Opportunities For Calidris Shorebirds, Aileen K. Miller, Catherine E. De Rivera

Environmental Science and Management Faculty Publications and Presentations

Estuarine intertidal habitats are heterogeneous, therefore migratory shorebirds are expected to forage in microhabitats where they can maximize their energy intake. Identifying proximate factors that migratory shorebirds use to accept or reject a particular habitat patch will help land managers make conservation and restoration decisions that provide the greatest benefits to shorebird populations during migration, a period of intense energy usage. We examined whether small semipermanent tidal channels were preferentially used by foraging Western Sandpipers (Calidris mauri) and Dunlins (C. alpina) during a spring migratory stopover in Bandon Marsh, an Oregon, USA, estuary. Further, we tested …

Winter Climate Change Affects Growing-Season Soil Microbial Biomass And Activity In Northern Hardwood Forests, Jorge Durán, Jennifer L. Morse, Peter M. Groffman, John L. Campbell, Lynn M. Christenson, Charles T. Driscoll, Timothy J. Fahey, Melany C. Fisk, Mryon J. Mitchell, Pamela H. Templer

Environmental Science and Management Faculty Publications and Presentations

Understanding the responses of terrestrial ecosystems to global change remains a major challenge of ecological research. We exploited a natural elevation gradient in a northern hardwood forest to determine how reductions in snow accumulation, expected with climate change, directly affect dynamics of soil winter frost, and indirectly soil microbial biomass and activity during the growing season. Soils from lower elevation plots, which accumulated less snow and experienced more soil temperature variability during the winter (and likely more freeze/thaw events), had less extractable inorganic nitrogen (N), lower rates of microbial N production via potential net N mineralization and nitrification, and higher …

Improving The Representation Of Roots In Terrestrial Models, Erica A.H. Smithwick, Melissa S. Lucash, M. Luke Mccormack, Gajan Sivandran

Environmental Science and Management Faculty Publications and Presentations

Root biomass, root production and lifespan, and root-mycorrhizal interactions govern soil carbon fluxes and resource uptake and are critical components of terrestrial models. However, limitations in data and confusions over terminology, together with a strong dependence on a small set of conceptual frameworks, have limited the exploration of root function in terrestrial models. We review the key root processes of interest to both field ecologists and modelers including root classification, production, turnover, biomass, resource uptake, and depth distribution to ask (1) what are contemporary approaches for modeling roots in terrestrial models? and (2) can these approaches be improved via recent …

Center for Lakes and Reservoirs Publications and Presentations

In recent years, public awareness of aquatic invasive species (AIS) has increased considerably in Oregon and elsewhere in the western U.S.. News articles, boat inspection stations and AIS permit programs have drawn attention to the threat of aquatic invasive species, especially animals like zebra mussels (Dreissena polymorpha), quagga mussels (Dreissena bugensis), and New Zealand mudsnails (Potamopyrgus antipodarum). However, invasive aquatic plants are also capable of causing severe impacts and may similarly be transferred between waterbodies on boats, trailers or other equipment. Heavy infestations can hinder recreational use by motorized and non-motorized boats, snag fishing lines, threaten the safety of swimmers …

Occurrence Of Synthetic Amino-Polycarboxylate Chelating Compounds In Oregon Surface Waters, Nathan A. Hersey Jan 2014

Occurrence Of Synthetic Amino-Polycarboxylate Chelating Compounds In Oregon Surface Waters, Nathan A. Hersey

Civil and Environmental Engineering Master's Project Reports

Cation sequestering compounds are contained in many industrial, commercial and personal care products. The most widely used chelating agents, EDTA and DTPA, are commonly found in natural and industrial settings. When chelating compounds are present, the activity and transport of metal cations in the environment and the uptake of metals in natural systems can be affected. Surface water samples from across the United States were analyzed, as well as local collection and analysis of surface waters and wastewater treatment plant effluent from around Northwest Oregon. Results indicate presence of synthetic chelating compounds in areas with human activity, and absence in …

Geology Faculty Publications and Presentations

The 2014 National Seismic Hazard Maps for the conterminous United States incorporate additional uncertainty in fault slip-rate parameter that controls the earthquake-activity rates than was applied in previous versions of the hazard maps. This additional uncertainty is accounted for by new geodesy- and geology-based slip-rate models for the Western United States. Models that were considered include an updated geologic model based on expert opinion and four combined inversion models informed by both geologic and geodetic input. The two block models considered indicate significantly higher slip rates than the expert opinion and the two fault-based combined inversion models. For the hazard …

Asymmetry Of Matter/Antimatter And Possibility Of Cpt Violations, Kai Pak Jan 2014

Asymmetry Of Matter/Antimatter And Possibility Of Cpt Violations, Kai Pak

University Honors Theses

Symmetries are an important area of study in physics, fundamental to the understanding of all aspects of Nature including the beginning and formation of the Universe, and how it appears to us today. While current quantum theories and experiments observe that CPT (Charge Conjugation, Parity, and Time Reversal) symmetry is conserved, there are speculations that this may not be the case with matter and antimatter and could provide answers as to why such a large asymmetry (also known as baryogenesis) exists between the two with normal matter completely dominating the observable Universe. Key to studying antimatter is the ability to …

Selected Critiques Of The Philosophical Underpinnings Of The Neoclassical School, Thomas Howell Jan 2014

Selected Critiques Of The Philosophical Underpinnings Of The Neoclassical School, Thomas Howell

University Honors Theses

This inquiry seeks to establish the importance of the critiques levied by Thorstein Veblen and Tony Lawson against the orthodox economics of a century ago and today. This paper puts forward the notion that Neoclassical school and its sub set known as marginal utility theory are constructed upon shaky philosophical and methodological foundations that include the hedonistic conception of man, Benthamite Utilitarianism, static equilibria, and the use of the mathematical deductivist method far beyond its scope of effectiveness. Writing in two different time periods, Veblen and Lawson comment upon the same essential methodological maladies and put forward alternative methodologies and …

Forms And Functions : Life-Anatomy Or Physiology?, Theresa Payne Jan 2014

Forms And Functions : Life-Anatomy Or Physiology?, Theresa Payne

University Honors Theses

Humans use metaphors to communicate internal concepts and connections of experience, and attempt to systematize metaphors used for a more coherent world view. The most structured system of metaphor is science. Theories are not actual representations of the phenomena present to experience, their purpose is to communicate abstracted experience and expected regularity. A science in desperate need of a conceptual, thus metaphoric, realignment is biology. The metaphors used to describe organisms have gone through varying incarnations focusing on either the vitalistic or mechanistic aspects of their appearance; function versus form, physiology or anatomy. The use of culturally relevant terminology can …

Using Acl2 To Verify Loop Pipelining In Behavioral Synthesis, Disha Puri, Sandip Ray, Kecheng Hao, Fei Xie Jan 2014

Using Acl2 To Verify Loop Pipelining In Behavioral Synthesis, Disha Puri, Sandip Ray, Kecheng Hao, Fei Xie

Civil and Environmental Engineering Faculty Publications and Presentations

Behavioral synthesis involves compiling an Electronic System-Level (ESL) design into its RegisterTransfer Level (RTL) implementation. Loop pipelining is one of the most critical and complex transformations employed in behavioral synthesis. Certifying the loop pipelining algorithm is challenging because there is a huge semantic gap between the input sequential design and the output pipelined implementation making it infeasible to verify their equivalence with automated sequential equivalence checking techniques. We discuss our ongoing effort using ACL2 to certify loop pipelining transformation. The completion of the proof is work in progress. However, some of the insights developed so far may already be of …

Values Mapping With Latino Forest Users: Contributing To The Dialogue On Multiple Land Use Conflict Management, Kelly Biedenweg, Lee Cerveny, Rebecca J. Mclain Jan 2014

Values Mapping With Latino Forest Users: Contributing To The Dialogue On Multiple Land Use Conflict Management, Kelly Biedenweg, Lee Cerveny, Rebecca J. Mclain

Institute for Sustainable Solutions Publications and Presentations

Values mapping that represents how humans associate with natural environments is useful for several purposes, including recognizing and addressing different perceptions of natural resource ownership and management priorities, documenting traditional ecological knowledge, and spatially identifying the public's perception of economic and non-economic services provided by natural resources (McLain et al. 2013). The majority of this work has been conducted in developing countries and with disenfranchised communities, where participatory mapping associated with natural resource management is more widely practiced. As access to GIS technology has expanded, however, several projects have tested the benefits of values mapping for natural resource management decisions …

Partitioning The Fitness Components Of Rna Populations Evolving In Vitro, Carolina Diaz Arenas, Niles Lehman Dec 2013

Partitioning The Fitness Components Of Rna Populations Evolving In Vitro, Carolina Diaz Arenas, Niles Lehman

Chemistry Faculty Publications and Presentations

All individuals in an evolving population compete for resources, and their performance is measured by a fitness metric. The performance of the individuals is relative to their abilities and to the biotic surroundings – the conditions under which they are competing – and involves many components. Molecules evolving in a test tube can also face complex environments and dynamics, and their fitnessmeasurements should reflect the complexity of various contributing factors as well. Here, the fitnesses of a set of ligase ribozymes evolved by the continuous in vitroevolution system were measured. During these evolution cycles there are three different catalytic …
