When Water Isn't Wet: The Evolution Of Water Right Mitigation In Washington State, Rachael Osborn, Michael Mayer May 2020

When Water Isn't Wet: The Evolution Of Water Right Mitigation In Washington State, Rachael Osborn, Michael Mayer

Seattle Journal of Technology, Environmental & Innovation Law

What is water right mitigation?

The allocation of surface and ground water resources for out of stream uses via the western water rights doctrine of prior appropriation comes with serious environmental consequences – depletion of streamflow and aquifers. Over-appropriation by water rights has led to deleterious impacts on natural resources, including salmon survival, water quality, and public uses of state waterways.

Because of the over-appropriated condition of Washington’s rivers and aquifers, the issuance of new water rights has until recently required water-for-water or in-kind mitigation, with the goal to directly compensate for deleterious impacts. Historically, the Water Resources Program of ...


Alternative Polyadenylation Modulates Expression Of Pro-Fibrotic Proteins And Contributes To Lung Fibrosis, Junsuk Ko May 2020

Alternative Polyadenylation Modulates Expression Of Pro-Fibrotic Proteins And Contributes To Lung Fibrosis, Junsuk Ko

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease which affects about 5 to 8 million individuals in the world. Despite the high prevalence, there is currently no cure for IPF, and the cause of this disease is still unclear. Our laboratory and collaborators have shown that nudix hydrolase 21 (NUDT21, which is also known as cleavage factor 25, CFIm25) is a key regulator of alternative polyadenylation (APA). NUDT21 depletion causes 3’UTR shortening via APA leading to enhanced mRNA stability and protein translation. This NUDT21 reduction promotes tumor growth in glioblastoma by enhancing expression of oncogenes. Cancer and IPF ...

269— Age Of Colon Cancer Screening - A Retrospective Review, Christopher Cook Apr 2020

269— Age Of Colon Cancer Screening - A Retrospective Review, Christopher Cook

GREAT Day

Colon cancer is the third most common cause of cancer-related death in the U.S. In 2019, the American Cancer Society predicted that 101,420 people in the U.S. would receive a new diagnosis of colon cancer. Due to this high prevalence, there has been a recent debate about the appropriate age to start colon cancer screening. Currently, the American Society of Gastroenterology recommends that screening start for average risk individuals at the age of 50. Conversely, the American Cancer Society has recently recommended that colon cancer screening for average risk individuals begin at the age of 45. The ...


Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel Apr 2020

Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel

Masters Theses & Specialist Projects

Substrate-borne vibrations, or biotremors, are utilized by vertebrates found in unique environments because biotremors are an effective way to transmit signals through dense media. Previous studies have shown that veiled chameleons (Chamaeleo calyptratus) are able to produce biotremors via specialized neck muscles. I hypothesized that during courtship and/or breeding, the veiled chameleon, a tree-dwelling species, would communicate with biotremors through branches. Additionally, I hypothesized that female call characteristics would differ between reproductive condition (i.e., receptive and non-receptive), while male call characteristics would differ between behavioral contexts (i.e., territorial vs. courtship). Chameleons were paired (one male, one female ...


Individual Behavior Drives Ecosystem Function And The Impacts Of Harvest, Jacob E. Allgeier, Timothy J. Cline, Timothy E. Walsworth, Gus Wathen, Craig A. Layman, Daniel E. Schindler Feb 2020

Individual Behavior Drives Ecosystem Function And The Impacts Of Harvest, Jacob E. Allgeier, Timothy J. Cline, Timothy E. Walsworth, Gus Wathen, Craig A. Layman, Daniel E. Schindler

Watershed Sciences Faculty Publications

Current approaches for biodiversity conservation and management focus on sustaining high levels of diversity among species to maintain ecosystem function. We show that the diversity among individuals within a single population drives function at the ecosystem scale. Specifically, nutrient supply from individual fish differs from the population average >80% of the time, and accounting for this individual variation nearly doubles estimates of nutrients supplied to the ecosystem. We test how management (i.e., selective harvest regimes) can alter ecosystem function and find that strategies targeting more active individuals reduce nutrient supply to the ecosystem up to 69%, a greater effect ...


Engaging Faculty In Preparing Students For Non-Academic Environmental Careers, Carmen R. Cid, Mark W. Brunson Feb 2020

Engaging Faculty In Preparing Students For Non-Academic Environmental Careers, Carmen R. Cid, Mark W. Brunson

Environment and Society Faculty Publications

As a biology major at New York University, I was introduced to ecology in a course that bused the class out of New York University's Greenwich Village campus every weekend, to investigate biodiversity patterns in nearby forests and wetlands. After a day crossing bogs and walking through forests, I would take the subway home, hip boots in hand, reflecting on how the day's activities connected to my routine city life. Engaging others in understanding the city connections to adjacent habitats became my life's work. As Dean of Arts and Sciences at a public liberal arts university, I ...


Application Of Optical Trapping To Obtain Single-Source Str Profiles From Forensically Relevant Body Fluid Mixtures With Modified Dna Analysis Workflow, Benjamin J. O'Brien Jan 2020

Application Of Optical Trapping To Obtain Single-Source Str Profiles From Forensically Relevant Body Fluid Mixtures With Modified Dna Analysis Workflow, Benjamin J. O'Brien

Theses and Dissertations

Current methods of mixture separation in forensic DNA laboratories typically deconvolute the mixture after analysis using statistical analysis or probabilistic genotyping. To save time and effort of labs already backlogged, a method to separate mixtures on a cellular level before analysis needs to be developed. Optical trapping is a method that uses a focused 1064 nm laser to manipulate cells. Previous research has shown that approximately 50 spermatozoa or 15 leukocytes from a liquid sample are required to produce a full STR DNA profile. It was found that the number of spermatozoa required remains constant when the method of sample ...


Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck Dec 2019

Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck

Wildland Resources Faculty Publications

Medium and large carnivores coexist with people in urban areas globally, occasionally resulting in negative interactions that prompt questions about how to reduce human-wildlife conflict. Hazing, i.e., scaring wildlife, is frequently promoted as an important non-lethal means for urbanites to reduce conflict but there is limited scientific evidence for its efficacy. We used a population of captive coyotes (Canis latrans) to simulate urban human-coyote interactions and subsequent effects of hazing on coyote behavior. Past experiences with humans significantly affected the number of times a coyote approached a human to necessitate hazing. Coyotes that had been hand fed by adults ...


Potential Distribution Of Six North American Higher-Attine Fungus-Farming Ant (Hymenoptera: Formicidae) Species, Sarah F. Senula, Joseph T. Scavetta, Joshua A. Banta, Ulrich G. Mueller, Jon N. Seal, Katrin Kellner Dec 2019

Potential Distribution Of Six North American Higher-Attine Fungus-Farming Ant (Hymenoptera: Formicidae) Species, Sarah F. Senula, Joseph T. Scavetta, Joshua A. Banta, Ulrich G. Mueller, Jon N. Seal, Katrin Kellner

Biology Faculty Publications and Presentations

Ants are among the most successful insects in Earth’s evolutionary history. However, there is a lack of knowledge regarding range-limiting factors that may influence their distribution. The goal of this study was to describe the environmental factors (climate and soil types) that likely impact the ranges of five out of the eight most abundant Trachymyrmex species and the most abundant Mycetomoellerius species in the United States. Important environmental factors may allow us to better understand each species’ evolutionary history. We generated habitat suitability maps using MaxEnt for each species and identified associated most important environmental variables. We quantified niche ...


Sage‐Grouse Breeding And Late Brood‐Rearing Habitat Guidelines In Utah, David K. Dahlgren, Terry Messmer, Benjamin A. Crabb, Michel Kohl, Shandra Nicole Frey, Eric T. Thacker, Randy T. Larsen, Rick J. Baxter Dec 2019

Sage‐Grouse Breeding And Late Brood‐Rearing Habitat Guidelines In Utah, David K. Dahlgren, Terry Messmer, Benjamin A. Crabb, Michel Kohl, Shandra Nicole Frey, Eric T. Thacker, Randy T. Larsen, Rick J. Baxter

Wildland Resources Faculty Publications

Delineation, protection, and restoration of habitats provide the basis for endangered and threatened species recovery plans. Species recovery plans typically contain guidelines that provide managers with a scientific basis to designate and manage critical habitats. As such, habitat guidelines are best developed using data that capture the full diversity of ecological and environmental conditions that provide habitat across the species’ range. However, when baseline information, which fails to capture habitat diversity, is used to develop guidelines, inconsistencies and problems arise when applying those guidelines to habitats within an ecologically diverse landscape. Greater sage‐grouse (Centrocercus urophasianus; sage‐ grouse) populations in ...


Improving Lake Mixing Process Simulations In The Community Land Model By Using K Profile Parameterization, Qunhui Zhang, Jiming Jin, Xiaochun Wang, Phaedra Budy, Nick Barrett, Sarah E. Null Dec 2019

Improving Lake Mixing Process Simulations In The Community Land Model By Using K Profile Parameterization, Qunhui Zhang, Jiming Jin, Xiaochun Wang, Phaedra Budy, Nick Barrett, Sarah E. Null

Watershed Sciences Faculty Publications

We improved lake mixing process simulations by applying a vertical mixing scheme, K profile parameterization (KPP), in the Community Land Model (CLM) version 4.5, developed by the National Center for Atmospheric Research. Vertical mixing of the lake water column can significantly affect heat transfer and vertical temperature profiles. However, the current vertical mixing scheme in CLM requires an arbitrarily enlarged eddy diffusivity to enhance water mixing. The coupled CLM-KPP considers a boundary layer for eddy development, and in the lake interior water mixing is associated with internal wave activity and shear instability. We chose a lake in Arctic Alaska ...


The Next Frontier: Making Research More Reproducible, David E. Rosenberg, Yves Fillion, Rebecca L. Teasley, Samuel Sandoval-Solis, Jory S. Hecht, Jakobus E. Van Zyl, George F. Mcmahon, Jeffery S. Horsburgh, Joseph R. Kasprzyk, David G. Tarboton Nov 2019

Publications

Science and engineering rest on the concept of reproducibility. An important question for any study is: are the results reproducible? Can the results be recreated independently by other researchers or professionals? Research results need to be independently reproduced and validated before they are accepted as fact or theory. Across numerous fields like psychology, computer systems, and water resources there are problems to reproduce research results (Aarts et al. 2015; Collberg et al. 2014; Hutton et al. 2016; Stagge et al. 2019; Stodden et al. 2018). This editorial examines the challenges to reproduce research results and suggests community practices to overcome ...

Soil nitrogen mineralisation (Nmin), the conversion of organic into inorganic N, is important for productivity and nutrient cycling. The balance between mineralisation and immobilisation (net Nmin) varies with soil properties and climate. However, because most global-scale assessments of net Nmin are laboratory-based, its regulation under field-conditions and implications for real-world soil functioning remain uncertain. Here, we explore the drivers of realised (field) and potential (laboratory) soil net Nmin across 30 grasslands worldwide. We find that realised Nmin is largely explained by temperature of the wettest quarter, microbial biomass, clay content and bulk density. Potential N ...


Climate Change Accelerates Recovery Of The Tatra Mountain Lakes From Acidification And Increases Their Nutrient And Chlorophyll A Concentrations, Jiří Kopáček, Jiří Kaňa, Svetlana Bičárová, Janice Brahney, Tomáš Navrátil, Stephen A. Norton, Petr Porcal, Evžen Stuchlik Oct 2019

Climate Change Accelerates Recovery Of The Tatra Mountain Lakes From Acidification And Increases Their Nutrient And Chlorophyll A Concentrations, Jiří Kopáček, Jiří Kaňa, Svetlana Bičárová, Janice Brahney, Tomáš Navrátil, Stephen A. Norton, Petr Porcal, Evžen Stuchlik

Janice Brahney

We evaluated changes in the concentration of cations, anions, nutrients (dissolved organic carbon, DOC; phosphorus, P; and nitrogen forms including nitrate, NO3 and total organic nitrogen, TON), and chlorophyll a (Chl-a) in 31 Tatra Mountain lakes in Slovakia and Poland during their recovery from acidic deposition (1992–2018). Typical effects of decreasing acidic deposition on the lakes’ water composition, such as decreasing base cation concentrations, were confounded by climate change and catchment characteristics, including areal proportions of well-developed soils and scree. A climate-related increase in physical erosion provided freshly exposed unweathered granodiorite (the dominant bedrock) to chemical weathering ...


Estimating Total And Bioavailable Nutrient Loading To Utah Lake From The Atmosphere, Janice Brahney Oct 2019

Estimating Total And Bioavailable Nutrient Loading To Utah Lake From The Atmosphere, Janice Brahney

Janice Brahney

Anthropogenic activities have led to increases in the emission, atmospheric transport, and deposition of key nutrients. In addition, climate change along with anthropogenic soil disturbance has led to recent increases in the mobilization and transport of soils and other particles through the atmosphere, collectively described here as dust. These increased emissions have led to growing interest and concern over the composition of atmospheric deposition and total loading of nutrients to aquatic systems. In the last several decades, much effort has been directed towards the measurement and modeling of nitrogen deposition through wet and aerosol deposition. Less is known about the ...

Timing Of Invasion By Africanized Bees Coincides With Local Extinction Of A Specialized Pollinator Of A Rare Poppy In Utah, Usa, Amber D. Tripodi, Vincent J. Tepedino, Zachary M. Portman Sep 2019

Timing Of Invasion By Africanized Bees Coincides With Local Extinction Of A Specialized Pollinator Of A Rare Poppy In Utah, Usa, Amber D. Tripodi, Vincent J. Tepedino, Zachary M. Portman

All PIRU Publications

The introduction of exotic species can have profound impacts on mutualisms between native species in invaded areas. However, determining whether a new invader has impacted native species depends on accurately reconstructing the invasion timing. The arrival of Africanized honey bees (AHB) in southern Utah at some point between 1994 and 2011 has recently been implicated in the local extinction of Perdita meconis, a native specialist pollinator of an endangered poppy, Arctomecon humilis. Although AHBs were purportedly first detected in southern Utah in 2008, their presence in nearby Nevada, Arizona, and New Mexico by 1998–2001 suggests that they may have ...

Background
The aim is to identify any gaps in the knowledge of folate and folic acid in vegetarians, which is of interest given the increasing adoption of vegetarian type diets.

Methods
In this convenience sample, 106 people answered an online questionnaire regarding folate intake and awareness among vegetarians. This was created using Google Forms and was shared via Facebook, including on various national and college vegetarian group pages. There were 44 questions. Twenty-four participants were excluded, because they reported eating fish, chicken or other meat. Final data analysis included 82 subjects. The majority of these vegetarians were females over the ...


Effects Of Severe Water Stress On Maize Growth Processes In The Field, Libing Song, Jiming Jin, Jianqiang He Sep 2019

Effects Of Severe Water Stress On Maize Growth Processes In The Field, Libing Song, Jiming Jin, Jianqiang He

Watershed Sciences Faculty Publications

In this study, we investigated the effects of water stress on the growth and yield of summer maize (Zea mays L.) over four phenological stages: Seedling, jointing, heading, and grain-filling. Water stress treatments were applied during each of these four stages in a water-controlled field in the Guanzhong Plain, China between 2013 and 2016. We found that severe water stress during the seedling stage had a greater effect on the growth and development of maize than stress applied during the other three stages. Water stress led to lower leaf area index (LAI) and biomass owing to reduced intercepted photosynthetically active ...


A Case For Eustress In Grazing Animals, Juan J. Villalba, Xavier Manteca Sep 2019

A Case For Eustress In Grazing Animals, Juan J. Villalba, Xavier Manteca

Wildland Resources Faculty Publications

Herbivores grazing in extensive systems are exposed to a series of challenges, rooted in the inherent spatial and temporal variability of their environment that potentially constrain their health, nutrition, and welfare. Nevertheless, in this review, we argue that challenges induced by some biotic (e.g., vegetation) and abiotic (e.g., terrain) factors may also be viewed as “positive” sources of stress or eustress, since they present complex problems, that when solved successfully elicit a greater degree of behavioral plasticity and adaptability in grazing animals. Chemically and structurally diverse landscapes require animals to display complex behaviors and exhibit adaptive capabilities, like ...


Use Of Low-Cost Ambient Particulate Sensors In Nablus, Palestine With Application To The Assessment Of Regional Dust Storms, Abdelhaleem Khader, Randal S. Martin Sep 2019

Use Of Low-Cost Ambient Particulate Sensors In Nablus, Palestine With Application To The Assessment Of Regional Dust Storms, Abdelhaleem Khader, Randal S. Martin

Publications

Few air pollutant studies within the Palestinian territories have been reported in the literature. In March–April and May–June of 2018, three low-cost, locally calibrated particulate monitors (AirU’s) were deployed at different elevations and source areas throughout the city of Nablus in Northern West Bank, Palestine. During each of the three-week periods, high but site-to-site similar particulate matter less than 2.5 µm in aerodynamic diameter (PM2.5) and less than 10 µm (PM10) concentrations were observed. The PM2.5 concentrations at the three sampling locations and during both sampling periods averaged 38.2 ± 3 ...

The term Blue Carbon (BC) was first coined a decade ago to describe the disproportionately large contribution of coastal vegetated ecosystems to global carbon sequestration. The role of BC in climate change mitigation and adaptation has now reached international prominence. To help prioritise future research, we assembled leading experts in the field to agree upon the top-ten pending questions in BC science. Understanding how climate change affects carbon accumulation in mature BC ecosystems and during their restoration was a high priority. Controversial questions included the role of carbonate and macroalgae in BC cycling, and the degree to which greenhouse gases ...


A Review And Updated Classification Of Pollen Gathering Behavior In Bees (Hymenoptera, Apoidea), Zachary M. Portman, Michael C. Orr, Terry Griswold Aug 2019

A Review And Updated Classification Of Pollen Gathering Behavior In Bees (Hymenoptera, Apoidea), Zachary M. Portman, Michael C. Orr, Terry Griswold

All PIRU Publications

Pollen is the primary protein and nutrient source for bees and they employ many different behaviors to gather it. Numerous terms have been coined to describe pollen gathering behaviors, creating confusion as many are not clearly-defined or overlap with existing terms. There is a need for a clear yet flexible classification that enables accurate, succinct descriptions of pollen gathering behaviors to enable meaningful discussion and comparison. Here, we classify the different pollen gathering behaviors into two main classes: active and incidental pollen collection. Active pollen collection is subdivided into six behaviors: scraping with the extremities, buzzing, rubbing with the body ...


Controls And Adaptive Management Of Nitrification In Agricultural Soils, Jeanette M. Norton, Yang Ouyang Aug 2019

Controls And Adaptive Management Of Nitrification In Agricultural Soils, Jeanette M. Norton, Yang Ouyang

Plants, Soils, and Climate Faculty Publications

Agriculture is responsible for over half of the input of reactive nitrogen (N) to terrestrial systems; however improving N availability remains the primary management technique to increase crop yields in most regions. In the majority of agricultural soils, ammonium is rapidly converted to nitrate by nitrification, which increases the mobility of N through the soil matrix, strongly influencing N retention in the system. Decreasing nitrification through management is desirable to decrease N losses and increase N fertilizer use efficiency. We review the controlling factors on the rate and extent of nitrification in agricultural soils from temperate regions including substrate supply ...


Environmental Differences Between Migratory And Resident Ungulates—Predicting Movement Strategies In Rocky Mountain Mule Deer (Odocoileus Hemionus) With Remotely Sensed Plant Phenology, Snow, And Land Cover, Benjamin Robb, Qiongyu Huang, Joseph O. Sexton, David C. Stoner, Peter Leimgruber Aug 2019

Environmental Differences Between Migratory And Resident Ungulates—Predicting Movement Strategies In Rocky Mountain Mule Deer (Odocoileus Hemionus) With Remotely Sensed Plant Phenology, Snow, And Land Cover, Benjamin Robb, Qiongyu Huang, Joseph O. Sexton, David C. Stoner, Peter Leimgruber

Wildland Resources Faculty Publications

Migration is a valuable life history strategy for many species because it enables individuals to exploit spatially and temporally variable resources. Globally, the prevalence of species’ migratory behavior is decreasing as individuals forgo migration to remain resident year-round, an effect hypothesized to result from anthropogenic changes to landscape dynamics. Efforts to conserve and restore migrations require an understanding of the ecological characteristics driving the behavioral tradeoff between migration and residence. We identified migratory and resident behaviors of 42 mule deer (Odocoileus hemionus) based on GPS locations and correlated their locations to remotely sensed indicators of forage quality, land cover, snow ...
