Climate Change, Snow Mold And The Bromus Tectorum Invasion: Mixed Evidence For Release From Cold Weather Pathogens, Danielle M. Smull, Nicole Pendleton, Andrew R. Kleinhesselink, Peter B. Adler
Ecology Center Publications
Climate change is reducing the depth and duration of winter snowpack, leading to dramatic changes in the soil environment with potentially important ecological consequences. Previous experiments in the Intermountain West of North America indicated that loss of snowpack increases survival and population growth rates of the invasive annual grass Bromus tectorum; however, the underlying mechanism is unknown. We hypothesized that reduced snowpack might promote B. tectorum population growth by decreasing damage from snow molds, a group of subnivean fungal pathogens. To test this hypothesis, we conducted greenhouse and field experiments to investigate the interaction between early snowmelt and either fungicide ...

Ruminant livestock-production systems are between a rock and a hard place; they are experiencing increasing societal pressure to reduce environmental impacts in a world that demands increased food supply. Recent improvements in the understanding of the nutritional ecology of livestock by scientists may help livestock producers respond to these seemingly contradictory demands. Forages are nutrition and pharmacy centers with primary (nutrients) and plant secondary compounds (PSC; pharmaceuticals, nutraceuticals), which can provide multiple services for the proper functioning of agroecosystems. Legumes with lower contents of fiber and higher contents of nonstructural carbohydrates, coupled with different types and concentrations of PSC (e ...
Carbonate Chemistry Characterization In A Low-Inflow Estuary With Recent Seagrass Loss, 2019 California Polytechnic State University, San Luis Obispo
Carbonate Chemistry Characterization In A Low-Inflow Estuary With Recent Seagrass Loss, Jolie Higgins
Estuaries are dynamic environments that are strongly affected by natural variability, as well as direct and indirect anthropogenic impacts. A better understanding of the drivers of carbon fluxes and biogeochemical variability in estuarine systems is needed, particularly with the increasing threat of ocean acidification. Morro Bay in Central California is a small nationally protected estuary, with seasonally low freshwater inputs. Since 2007, the bay has experienced a significant loss of native seagrass, Zostera marina, which is an important component of the marine ecosystem. Because seagrass photosynthesis decreases carbon dioxide and increases oxygen in the water column, the loss of seagrass ...
Fuel Dynamics After Reintroduced Fire In An Old-Growth Sierra Nevada Mixed-Conifer Forest, 2019 Rocky Mountain Research Station
Fuel Dynamics After Reintroduced Fire In An Old-Growth Sierra Nevada Mixed-Conifer Forest, C. Alina Cansler, Mark E. Swanson, Tucker J. Furniss, Andrew J. Larson, James A. Lutz
Wildland Resources Faculty Publications
Background: Surface fuel loadings are some of the most important factors contributing to fire intensity and fire spread. In old-growth forests where fire has been long excluded, surface fuel loadings can be high and can include woody debris ≥100 cm in diameter. We assessed surface fuel loadings in a long-unburned old-growth mixed-conifer forest in Yosemite National Park, California, USA, and assessed fuel consumption from a management-ignited fire set to control the progression of the 2013 Rim Fire. Specifically, we characterized the distribution and heterogeneity of pre-fire fuel loadings, both along transects and contained in duff mounds around large trees. We ...

Uncharted Territory: Uvm Extension Data Visualization Needs Assessment, 2019 University of Vermont
Uncharted Territory: Uvm Extension Data Visualization Needs Assessment, Sarah E. Lyman
Food Systems Master's Project Reports
Graphical displays are more effective than textual information at summarizing large volumes of data, improving retention of information, and in persuading behavior change. UVM Extension uses data visualizations every day in its mission to transform academic research into practical recommendations for Vermonters, in topics ranging from nutrition to agriculture. But how are these graphics generated across an organization with more than 100 employees? How can data visualization help advance goals which range from analyzing research to demonstrating community impact? This paper presents the results of a Master’s project study into what tools and skills are already being used at ...

The Role Of Gene Expression Noise In Mammalian Cell Survival, 2019 The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences
The Role Of Gene Expression Noise In Mammalian Cell Survival, Kevin Farquhar
The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)
Drug resistance and metastasis remain obstacles to effective cancer treatment. A major challenge contributing to this problem is cellular heterogeneity. Even in the same environment, cells with identical genomes can display cell-to-cell differences in gene expression, also known as gene expression noise. Gene expression noise can vary in magnitude in a population or in fluctuation time scales, which is influenced by gene regulatory networks.
Currently, it is unclear how gene expression noise from gene regulatory networks contributes to drug survival outcomes in mammalian cells. An isogenic cell line with a noise-modulating genetic system tuned to the same mean is required ...
Cultural Competence: Issues And Benefits In Healthcare Delivery, 2019 CUNY New York City College of Technology
Cultural Competence: Issues And Benefits In Healthcare Delivery, Tetiana Soloviova, Amina Shahbaz, Fahaneda Hassan, Zoya Vinokur
Publications and Research
The extreme growth of New York State population causes to bring more challenges and opportunities for healthcare organization to provide culturally competent service to meet the need of diverse population. According to data from the US Census Bureau, minority groups are projected to make up nearly 50% of the population by the year 2050 compared with 30% in 2000. Outside of ethnicity, there are also many cultural and social groups with which people identify that may affect how they view or receive healthcare. It is very difficult to provide quality service for a diverse population due to language barriers, health ...
Latino Stepcouples’ Experiences Two Years After Stepfamily Education And A Narrative Study Regarding Changes In A Latino Stepfamily Two Years After Stepfamily Education, Sheryl Ann Goodey
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 ...
Behavioral Responses To Ancestral Predators In Vervet Monkeys (Chlorocebus Pygerythrus) On Misali Island, Tanzania, Isabelle Hanna
Independent Study Project (ISP) Collection
The success of a species depends largely on their ability to recognize and respond to predatory cues. These responses can be controlled through genetic or social factors. This study aimed to assess the ability of vervet monkeys (Chlorocebus pygerythrus) to identify and respond to ancestral predatory cues following long-term isolation on Misali Island, Zanzibar, Tanzania in order to determine if anti-predator behaviors are innate or learned. This was accomplished through exposure of troops to auditory predator cues and the documentation of their behavioral responses. The results of these trials suggest that predator recognition is an innate behavior in C. pygerythrus ...
Establishment Of Fuel Breaks To Protect Sage-Grouse Habitat In Northwest Utah, 2019 Utah State University
Establishment Of Fuel Breaks To Protect Sage-Grouse Habitat In Northwest Utah, William Price
Research on Capitol Hill
One of the largest threats to greater sage-grouse (Centrocercus ursophasianus) is habitat loss due to wildfire. Cheatgrass is an invasive annual grass that increases the frequency and severity of wildfire, creating an even larger threat to sage-grouse.
One approach to protect sage-grouse habitat is to implement fuel breaks of perennial grasses to slow the spread of wildfire. Perennial grasses are used in these fuel breaks because they stay green longer into the summer and are more resistant to the spread of fire.
The fuel breaks were implemented in Dry Basin in 2016 and Badger Flat in 2011 by removing the ...
Comparison Of Periglacial Block Fields And Talus Slopes In South-Central Pennsylvania And Northern Maryland, Ilana B. Sobel, Abigail F. Rec, Sarah M. Principato
Environmental Studies Faculty Publications
Relict periglacial boulder fields, or block fields, are scattered across south-central Pennsylvania and northern Maryland (e.g. Potter and Moss, 1968; Denn et al 2018). This pilot study uses a combination of digital analyses using Google Earth Pro and fieldwork to investigate block fields at different scales. Fieldwork focused on two block fields, which were compared with fieldwork conducted on two talus slopes. The block fields studied were Raven Rock Hollow in Maryland and River of Rocks at Hawk Mountain in Pennsylvania, and the talus slopes were located at Catoctin Mountain, Maryland and Waggoner’s Gap, Pennsylvania. The importance of ...
How To Combat Post-Natural Disaster Related Environmental Gentrification And Environmental Inequality Accelerated By Climate Change, 2019 Union College - Schenectady, NY
How To Combat Post-Natural Disaster Related Environmental Gentrification And Environmental Inequality Accelerated By Climate Change, Marielle Christie
This thesis aims to illustrate the concept of natural disaster-induced environmental gentrification. There is a heightened vulnerability to unmitigated forced displacement by socioeconomically disadvantaged residents following a natural disaster. Environmental gentrification is a variant of green gentrification. Green gentrification occurs when providing green amenities to a city increases local property values and attracts wealthier residents to a previously polluted or disenfranchised neighborhood, which displaces the low-income residents. Similarly, environmental gentrification is a process that occurs after a natural disaster and rapidly accelerates the process of traditional urban gentrification or green gentrification. As a result, environmental gentrification magnifies and facilitates further ...
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 Dupey, 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 ...
Seasonal Origins Of Soil Water Used By Trees, 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 ...
Phylogenetic And Biogeographic Controls Of Plant Nighttime Stomatal Conductance, 2019 University of Utah
Phylogenetic And Biogeographic Controls Of Plant Nighttime Stomatal Conductance, Kailiang Yu, Gregory R. Goldsmith, Yujie Wang, William R. L. Anderegg
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The widely documented phenomenon of nighttime stomatal conductance (gsn) could lead to substantial water loss with no carbon gain, and thus it remains unclear whether nighttime stomatal conductance confers a functional advantage. Given that studies of gsn have focused on controlled environments or small numbers of species in natural environments, a broad phylogenetic and biogeographic context could provide insights into potential adaptive benefits of gsn.
We measured gsn on a diverse suite of species (n = 73) across various functional groups and climates‐of‐origin in a common garden to study the phylogenetic and biogeographic/climatic controls ...
The Intrepid Urban Coyote: A Comparison Of Bold And Exploratory Behavior In Coyotes From Urban And Rural Environments, 2019 USDA/APHIS/WS National Wildlife Research Center
The Intrepid Urban Coyote: A Comparison Of Bold And Exploratory Behavior In Coyotes From Urban And Rural Environments, Stewart W. Breck, Sharon A. Poessel, Peter Mahoney, Julie Young
Wildland Resources Faculty Publications
Coyotes (Canis latrans) are highly adaptable, medium-sized carnivores that now inhabit nearly every large city in the United States and Canada. To help understand how coyotes have adapted to living in urban environments, we compared two ecologically and evolutionarily important behavioral traits (i.e., bold-shy and exploration-avoidance behavior) in two contrasting environments (i.e., rural and urban). Boldness is an individual’s reaction to a risky situation and exploration is an individual’s willingness to explore novel situations. Our results from both tests indicate that urban coyotes are bolder and more exploratory than rural coyotes and that within both populations ...
