All Graduate Theses and Dissertations

There are two studies in this dissertation. Both are about couples in a stepfamily who attended stepfamily education called, Smart Steps: Embrace the Journey. The first study explored how 13 Latino stepcouples felt the concepts they learned in stepfamily education influenced their couple relationship, parenting, and their family. Participants ranged in age from 25 to 43. They were interviewed two years after participating in the course. They talked about positive changes that happened in their couple relationship, parenting relationship, and their family as a result of participating in stepfamily education. It was also found that the course helped them to ...


Seasonal Origins Of Soil Water Used By Trees, Scott T. Allen, James W. Kirchner, Sabine Braun, Rolf T. W. Siegwolf, Gregory R. Goldsmith 2019 ETH Zurich

Seasonal Origins Of Soil Water Used By Trees, Scott T. Allen, James W. Kirchner, Sabine Braun, Rolf T. W. Siegwolf, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Rain recharges soil water storages and either percolates downward into aquifers and streams or is returned to the atmosphere through evapotranspiration. Although it is commonly assumed that summer rainfall recharges plant-available water during the growing season, the seasonal origins of water used by plants have not been systematically explored. We characterize the seasonal origins of waters in soils and trees by comparing their midsummer isotopic signatures (δ2H) to seasonal isotopic cycles in precipitation, using a new seasonal origin index. Across 182 Swiss forest sites, xylem water isotopic signatures show that summer rain was not the predominant water source for ...


Close But No Cigar: How A Near-Miss Wildfire Event Influences The Risk Perceptions And Mitigation Behaviors Of Residents Who Experienced A Recent, Nearby Wildfire, Lauren Nicole Dudley, Jordan W. Smith 2019 Utah State University

Close But No Cigar: How A Near-Miss Wildfire Event Influences The Risk Perceptions And Mitigation Behaviors Of Residents Who Experienced A Recent, Nearby Wildfire, Lauren Nicole Dudley, Jordan W. Smith

All Current Publications

This research used Protection Motivation Theory to examine if and how individuals who experience a near-miss wildfire event (i.e., a recent, proximal wildfire that did not harm these individuals or their properties) intend to protect themselves against future risks. We administered a drop-off pick-up survey to residents living in Durango, Colorado, a community heavily impacted by the 416 fire in the spring and summer of 2018. The survey, completed by 195 residents, solicited information about wildfire mitigation behaviors taken before and after the 416 fire. Data were also collected on four of the dimensions of Protection Motivation Theory which ...

Oil spills in oceans have substantial influence on marine ecosystems. This study investigates 21 oil spills in the world. Analyzing Chlorophyll-a (Chl-a) from Moderate Resolution Imaging Spectroradiomerer (MODIS) data after Penglai oil spills on 4 June 2011, found a bloom with peak value of Chl-a (13.66 mg m−3) spread over an area of 800 km2 during 18–25 June 2011, and a pronounced increase in the monthly Chl-a concentration (6.40 mg m−3) on June 2012 in the Bohai Sea. Out of the 21 oil spills, 14 blooms were observed, while 11 ...


Geospatial Modeling Of Land Cover Change In The Chocó-Darien Global Ecoregion Of South America; One Of Most Biodiverse And Rainy Areas In The World, José Camilo Fagua, R. Douglas Ramsey 2019 Utah State University

Geospatial Modeling Of Land Cover Change In The Chocó-Darien Global Ecoregion Of South America; One Of Most Biodiverse And Rainy Areas In The World, José Camilo Fagua, R. Douglas Ramsey

Ecology Center Publications

The tropical rain forests of northwest South America fall within the Chocó-Darien Global Ecoregion (CGE). The CGE is one of 25 global biodiversity hotspots prioritized for conservation due to its high biodiversity and endemism as well as threats due to deforestation. The analysis of land-use and land-cover (LULC) change within the CGE using remotely sensed imagery is challenging because this area is considered to be one of the rainiest places on the planet (hence high frequency of cloud cover). Furthermore, the availability of high-resolution remotely sensed data is low for developing countries before 2015. Using the Random Forest ensemble learning ...

Anthropogenic infrastructure can negatively affect wildlife through direct mortality and/or displacement behaviors. Some tetranoids (grouse spp.) species are particularly vulnerable to tall anthropogenic structures because they evolved in ecosystems void of vertical structures. In western North America, electric power transmission and distribution lines (power lines) occur in sagebrush (Artemisia spp.) landscapes within the range of the greater sage-grouse (Centrocercus urophasianus; sage-grouse). The U.S. Fish and Wildlife Service recommended using buffer zones near leks to mitigate the potential impacts of power lines on sage-grouse. However, recommended buffer distances are inconsistent across state and federal agencies because data are lacking ...


Concept Inventories As A Resource For Teaching Evolution, Robert E. Furrow, Jeremy L. Hsu 2019 University of California, Davis

Concept Inventories As A Resource For Teaching Evolution, Robert E. Furrow, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Understanding evolution is critical to learning biology, but few college instructors take advantage of the body of peer-reviewed literature that can inform evolution teaching and assessment. Here we summarize the peer-reviewed papers on tools to assess student learning of evolutionary concepts. These published concept inventories provide a resource for instructors to design courses, gauge student preparation, identify key misconceptions in their student population, and measure the impact of a lesson, course, or broader curriculum on student learning. Because these inventories vary in their format, target audience, and degree of validation, we outline and explain these features. In addition to summarizing ...


Assessment Of The Effects Of Climate Change On Evapotranspiration With An Improved Elasticity Method In A Nonhumid Area, Lei Tian, Jiming Jin, Pute Wu, Guo-yue Niu 2018 Utah State University

Assessment Of The Effects Of Climate Change On Evapotranspiration With An Improved Elasticity Method In A Nonhumid Area, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu

Watershed Sciences Faculty Publications

Climatic elasticity is a crucial metric to assess the hydrological influence of climate change. Based on the Budyko equation, this study performed an analytical derivation of the climatic elasticity of evapotranspiration (ET). With this derived elasticity, it is possible to quantitatively separate the impacts of precipitation, air temperature, net radiation, relative humidity, and wind speed on ET in a watershed. This method was applied in the Wuding River Watershed (WRW), located in the center of the Yellow River Watershed of China. The estimated rate of change in ET caused by climatic variables is −10.69 mm/decade, which is close ...

Watershed Sciences Faculty Publications

Understanding hydrological responses to climate change and land use and land cover change (LULCC) is important for water resource planning and management, especially for water-limited areas. The annual streamflow of the Wuding River Watershed (WRW), the largest sediment source of the Yellow River in China, has decreased significantly over the past 50 years at a rate of 5.2 mm/decade. Using the Budyko equation, this study investigated this decrease with the contributions from climate change and LULCC caused by human activities, which have intensified since 1999 due to China’s Grain for Green Project (GFGP). The Budyko parameter that ...

When Strange Bedfellows Go All In: A Template For Implementing Non-Lethal Strategies Aimed At Reducing Carnivore Predation Of Livestock, Julie K. Young, John Steuber, Alexandra Few, Adam Baca, Zack Strong 2018 Utah State University

When Strange Bedfellows Go All In: A Template For Implementing Non-Lethal Strategies Aimed At Reducing Carnivore Predation Of Livestock, Julie K. Young, John Steuber, Alexandra Few, Adam Baca, Zack Strong

Wildland Resources Faculty Publications

In the Rocky Mountains of the USA, abundances and distributions of grizzly bear Ursus arctos and gray wolf Canis lupus have increased (Bangs et al., 2001; Nicholson & Hendricks, 2018). This has led to increased predation of livestock in areas where livestock producers have not needed to implement conflict prevention methods in recent history. Lethal removal of carnivores that kill livestock remains a common source of carnivore mortalities (Woodroffe, 2001; Broekhuis, Cushman & Elliot, 2017). In the USA, the U.S. Department of Agriculture’s Wildlife Services (USDA-WS) is often asked by the U.S. Fish and Wildlife Service or a State’s wildlife management agency to lethally remove large carnivores that depredate livestock. Where possible, conservation practitioners favor increased use of non-lethal tools to replace lethal methods aimed at preventing depredation of livestock. Conservation groups often dispute management actions for large carnivores, sometimes ...

Landscape Heterogeneity Strengthens The Relationship Between Β-Diversity And Ecosystem Function, Edd Hammill, Charles P. Hawkins, Hamish S. Greig, Pavel Kratina, Johathan B. Shurin, Trisha B. Atwood

Watershed Sciences Faculty Publications

Consensus has emerged in the literature that increased biodiversity enhances the capacity of ecosystems to perform multiple functions. However, most biodiversity/ecosystem function studies focus on a single ecosystem, or on landscapes of homogenous ecosystems. Here, we investigate how increased landscape‐level environmental dissimilarity may affect the relationship between different metrics of diversity (α, β, or γ) and ecosystem function. We produced a suite of simulated landscapes, each of which contained four experimental outdoor aquatic mesocosms. Differences in temperature and nutrient conditions of the mesocosms allowed us to simulate landscapes containing a range of within‐landscape environmental heterogeneities. We found ...


The Effects Of Seawater Temperature On Photosynthesis In Crustose Coralline Algae, Alexander Carlson 2018 SIT Study Abroad

The Effects Of Seawater Temperature On Photosynthesis In Crustose Coralline Algae, Alexander Carlson

Independent Study Project (ISP) Collection

Crustose Coralline Algae (CCA) are prolific reef builders and primary producers that play a key role in maintaining the structural integrity of coral reef systems (Littler and Littler, 2013). They are also highly important in increasing reef resilience by serving as a substrate for the recruitment and metamorphosis of coral larvae (Chisholm, 2000). Little is known about the way in which increasing seawater temperatures due to climate change might affect metabolic rates like photosynthesis in CCA. Therefore, a study was carried out in November, 2018, in the lab at Lizard Island Research Station to explore the photosynthetic performance of a ...

In the United States, the Clean Water Act (CWA) establishes water quality standards important for maintaining healthy freshwater ecosystems. Within the CWA framework, states define their own water quality criteria, leading to a potential fragmentation of standards between states. This fragmentation can influence the management of shared water resources and produce spillover effects of pollutants crossing state lines and other political boundaries. We used numerical simulations to test the null prediction of no difference in impairment between watersheds that cross political boundaries (i.e. state lines, national or coastal borders, hereafter termed “transboundary”) and watersheds that cross no boundaries (hereafter ...


Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy 2018 The University of Southern Mississippi

Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy

Master's Theses

There is currently a lack of modeling framework to predict how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological regimes. These interactions have not been comprehensively investigated before. I further modified this model to assess the efficacy of restoration projects from ...


Effects Of Eutrophication On Birds In Three Bays Of Great Salt Lake: A Comparative Analysis With Utah Dwr Waterbird Survey Data, Wayne A. Wurtsbaugh 2018 Utah State University

Effects Of Eutrophication On Birds In Three Bays Of Great Salt Lake: A Comparative Analysis With Utah Dwr Waterbird Survey Data, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Farmington Bay and Bear River support massive numbers of migratory birds. Because of Farmington Bay’s high nutrient loading and hypereutrophic condition, the Utah DWQ has proposed to list it as impaired under EPA’s and Utah’s 303d criteria. There is concern, however, that changing nutrient loading might influence invertebrate prey of birds, but it is not known if this would be a positive or negative effect. Bear River Bay is far less eutrophic, but has a similar shallow morphometry, and thus presents an ideal comparative opportunity to assess the influence of eutrophication on birds.

From 2007‐2011 the ...

Cross-fostering offspring with nonbiological parents could prove useful to augment populations of endangered carnivores. We used cross-fostering to augment captive-born and wild-born litters for the endangered red wolf (Canis rufus). Between 1987 and 2016, 23 cross-fostering events occurred involving captive-born pups fostered into captive litters (n = 8 events) and captive-born pups fostered into wild recipient litters (n = 15 events). Percentage of pups surviving 3 and 12 months was 91.7% for captive-born pups fostered into captive recipient litters. For pups fostered into wild litters, percentage of pups surviving 5 months was > 94% among fostered pups (pups fostered into a wild ...


Complexities And Challenges Of Nonduality, Elizabeth Stephens 2018 California Institute of Integral Studies

Complexities And Challenges Of Nonduality, Elizabeth Stephens

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

States of consciousness referred to as nonduality, awakening, enlightenment, moksha, peak experience, unitive states, or void states, among other terms, have garnered increasing secular attention and have become a topic of psychological and neuroscientific research. A review of the literature revealed many challenges to studying this set of states, such as inconsistent conceptualizations, a variety of models and theories, and conflicting descriptions indicating that the actual experience may not live up to the superlative descriptions found in historical texts or the expectations put forth by nondual teachers. A great deal more empirical research on this topic is needed, and researchers ...


Role Of Indochina Peninsula Topography In Precipitation Seasonality Over East Asia, Chi-Hua Wu, Wan-Ru Huang, S.-Y. (Simon) Wang 2018 Academia Sinica

Role Of Indochina Peninsula Topography In Precipitation Seasonality Over East Asia, Chi-Hua Wu, Wan-Ru Huang, S.-Y. (Simon) Wang

Plants, Soils, and Climate Faculty Publications

Stage-wise precipitation evolution over East Asia, primarily from spring to summer, is influenced by nearby monsoons and can be topographically driven. Corresponding to the onset of the Asian summer monsoon circulation, the Meiyu-Baiu occurs rapidly in May, replacing the East Asian spring rains. The Meiyu-Baiu rapidly terminates in late July due to the synchronous development of the subtropical monsoons extending from Africa to the East Asia–Western North Pacific (WNP). In late summer–autumn, the monsoonal circulation gradually retreats, in contrast to the rapid and stepwise transitions of the monsoon. This study reviews the role of the Indochina Peninsula in ...
