Quantifying The Ecological Effects Of Salix Fragilis On Riparian Habitat In Kittitas County, Washington, 2024 Central Washington University
Quantifying The Ecological Effects Of Salix Fragilis On Riparian Habitat In Kittitas County, Washington, Landon Shaffer
All Master's Theses
Invasive species threaten plant community structure and function globally. Riparian areas, the zone near streams where water influences vegetation, are especially sensitive to invasive species colonization, suffering large-scale shifts in community composition. Salix fragilis (crack willow) is a nonnative riparian species abundant in the lower elevation tributaries of central Washington. Some speculate whether this willow should be listed as invasive in Washington, despite a lack of regional supporting evidence. I studied riparian communities dominated by either S. fragilis or native species in the Kittitas Valley and measured biodiversity, quantified differences in solar attenuation, and compared leaf decomposition rates to learn …
Predicting Leucotaraxis Spp. Adult Emergence In The Pacific Northwest With Implications For Biological Control Of Hemlock Woolly Adelgid In The Eastern United States, 2024 University of Vermont
Predicting Leucotaraxis Spp. Adult Emergence In The Pacific Northwest With Implications For Biological Control Of Hemlock Woolly Adelgid In The Eastern United States, Liam Farley
Graduate College Dissertations and Theses
Hemlock woolly adelgid (Adelges tsugae) is a non-native, invasive pest of eastern hemlock (Tsugae canadensis) and Carolina hemlock (Tsugae caroliniana), both of which are considered important foundation species in forest ecosystems. Adelges tsugae has caused widespread decline and mortality of hemlock trees in eastern North America. Native hemlocks are particularly vulnerable because of the absence of co-evolved plant defenses and lack of natural enemies of A. tsugae. Managing A. tsugae through development of a biological control program has great potential at the regional level. Two species of silver fly from the Pacific northwest (PNW) Leucotaraxis argenticollis and Leucotaraxis piniperda are …

Permafrost degradation in peatlands is altering vegetation and soil properties and impacting net carbon storage. We studied four adjacent sites in Alaska with varied permafrost regimes, including a black spruce forest on a peat plateau with permafrost, two collapse scar bogs of different ages formed following thermokarst, and a rich fen without permafrost. Measurements included year-round eddy covariance estimates of net carbon dioxide (CO2), mid-April to October methane (CH4) emissions, and environmental variables. From 2011 to 2022, annual rainfall was above the historical average, snow water equivalent increased, and snow-season duration shortened due to later snow return. Seasonally thawed active …

Regis University Student Publications (comprehensive collection)
Human wildlife interactions (HWI) pose a complex challenge for wildlife managers. Human encroachment into wildlife habitat and the growing number of outdoor recreationists are increasing the frequency of contact and conflict, especially in regions such as the Front Range of Colorado. Geographic information systems (GIS), which use a combination of remote sensing and environmental survey data, allow for predictive spatial analyses of where human wildlife interactions are likely to occur. I used publicly reported observations of moose to create spatial predictive maps in a species distribution model framework. Slope and elevation were shown to be the strongest predictors of HWI, …

Sustainable and effective remediation technologies for the treatment of soil contaminated with per- and polyfluoroalkyl substances (PFAS) are greatly needed. This study investigated the effects of waste-based biochars on the leaching of PFAS from a sandy soil with a low total organic carbon content (TOC) of 0.57 ± 0.04% impacted by PFAS from aqueous film forming foam (AFFF) dispersed at a former fire-fighting facility. Six different biochars (pyrolyzed at 700–900°C) were tested, made from clean wood chips (CWC), waste timber (WT), activated waste timber (aWT), two digested sewage sludges (DSS-1 and DSS-2) and de-watered raw sewage sludge (DWSS). Up-flow column …
Assessing Changing Carbon Pool Dynamics And Species Composition In A Pennsylvania Broadleaf Forest Fragment, 2024 West Chester University of Pennsylvania
Assessing Changing Carbon Pool Dynamics And Species Composition In A Pennsylvania Broadleaf Forest Fragment, Kyleigh Levinsky, Jessica L. Schedlbauer
Sustainability Research & Creative Activities Grants Reports
Temperate broadleaf forests are pivotal to the global carbon cycle, Representing 37% of the global forest carbon pool (Pan et al 2011). • Maintaining compositional diversity in temperate broadleaf forests, such as the Gordon Natural Area (GNA) is critical to maintaining ecosystem services, such as carbon sequestration. • Pressures from native and non-native herbivores threaten the biodiversity of temperate broadleaf forests in the United States (Ghandi et al. 2010). The introduction of non-native insects such as the emerald ash borer (Argrilus planipennis), as well as the overpopulation of white-tailed deer (Odocoileus virginianus) has led to declines in some tree species. …

A Conservation Model: Costa Rican Conservation Strategies Effectively Preserve Their Threatened Primates, Ryan Belmont
Regis University Student Publications (comprehensive collection)
The wildlife of Costa Rica has experienced various anthropogenic threats over the last century including climate change and agricultural expansion. The mantled howler monkey (Alloutta palliata), Central American spider monkey (Ateles geoffroyi), white-faced capuchin (Cebus imitator), and the Central American squirrel monkey (Saimiri oerstedii) are Costa Rica’s native primates that face several anthropogenic threats such as deforestation for agriculture and climate change. In response to increased threats to its four native species of non-human primates, Costa Rica has implemented effective governmental conservation tactics such as the Payments for Environmental Services program, ecotourism …
Movement Behavior And Metapopulation Connectivity Of Stream Salamanders In Response To Disturbance Events, 2024 University of Kentucky
Movement Behavior And Metapopulation Connectivity Of Stream Salamanders In Response To Disturbance Events, Kathryn M. Greene
Theses and Dissertations--Biology
Metapopulations are shaped by the dispersal between populations in a landscape. Disturbance events can disrupt this connectivity resulting in local population extinction. For my dissertation, I used a combination of empirical and theoretical techniques to examine dispersal in response to disturbance and assessed it’s population-level consequences. My research used capture-mark-recapture sampling techniques to evaluate stream salamander movement in response to (1) a supraseasonal drought and (2) mountaintop-removal-mining (MTR) and valley-filling (VF) and (3) agent-based simulation modeling to evaluate population extinction risk in response to varying dispersal and mortality rates.
First, I evaluated the effects of a supraseasonal drought, a severe …

Long Oligodeoxynucleotides: Chemical Synthesis, Isolation Via Catching-By-Polymerization, Verification Via Sequencing, And Gene Expression Demonstration, Yipeng Yin, Reed Arneson, Alexander Apostle, Adikari M.D.N. Eriyagama, Komal Chillar, Emily Burke, Martina Jahfetson, Yinan Yuan, Shiyue Fang
Michigan Tech Publications, Part 2
Long oligodeoxynucleotides (ODNs) are segments of DNAs having over one hundred nucleotides (nt). They are typically assembled using enzymatic methods such as PCR and ligation from shorter 20 to 60 nt ODNs produced by automated de novo chemical synthesis. While these methods have made many projects in areas such as synthetic biology and protein engineering possible, they have various drawbacks. For example, they cannot produce genes and genomes with long repeats and have difficulty to produce sequences containing stable secondary structures. Here, we report a direct de novo chemical synthesis of 400 nt ODNs, and their isolation from the complex …

In recent times, plastic has become a highly favored choice for packaging due to its exceptional microbial, damage, and water-resistant properties. However, the alarming rise in plastic usage has led to adverse environmental pollution. This study aims to develop innovative food packaging solutions using renewable and compostable cellulose nanofibrils (CNFs). This thesis comprises two related studies on the barrier performance of novel food packaging materials, including oxygen barrier and oil/grease barrier properties. The goal of the first study was to enhance the mechanical and barrier properties of the cellulose nanofibril (CNF) films by inducing fibrils orientation for food packaging applications. …
Regeneration Response To Salvage Logging Following Tornado Disturbance, 2023 University of Maine
Regeneration Response To Salvage Logging Following Tornado Disturbance, Colby K. Bosley-Smith
Electronic Theses and Dissertations
In an era of increasing natural disturbances, successful tree regeneration has grown more difficult to achieve. Salvage logging, a common management response to disturbance, may further impede regeneration success, although published literature currently remains inconclusive. In 2013, a rare tornado in northcentral Maine, USA, and subsequent salvage operation created three clear ‘treatments’ for evaluation of post-disturbance regeneration: blowdown, blowdown followed by salvage logging and an undisturbed control. In the summers of 2022 and 2023, (nine and ten) years post-tornado, we revisited this site to examine regeneration outcomes.
During the summer of 2022, we evaluated stand structure and regeneration success of …
