On top of this map is a hillshade file that accentuates the perception of height in the mountains. On top of these layers are vector files showing the location of each cell phone tower in Maine, along with the corresponding service area. I found this map to be particularly interesting because it is able to show population density in an indirect way. Additionally, it highlights how …

Susceptibility Of United States Ski Resorts To The Effects Of Climate Change, Greyson M. Butler

Atlas of Maine

Across large regions of North America, warming global temperatures are expected to detrimentally reduce mountain snowpack accumulation and duration during the winter months. Mountain resorts are reliant on snowpack to generate a significant portion of their income through the ski industry. By 2100, experts have predicted that many alpine ski resorts could lose up to 70% of natural snow cover, leaving many resorts needing to turn to expensive, artificial snowmaking to supplement natural snowfall.

This study attempts to model the potential impact climate change will have on US ski resorts’ abilities to generate snowpack during the winter months in 2070 …

In this study we ask what parts of Maine have the highest number of different native tree species. Additionally, we investigate whether development is increasing in the areas with highest species richness. Shifts in population location can lead to more development, patch creation, and put strain on an ecosystem.

Forecasting Lava Flow: Analysis Of Potential Lava Flow Paths From Mauna Loa Volcano, Hi, Caroline Winslow, Julia Saul

Atlas of Maine

The island of Hawaii, located in the Hawaiian Island chain (Figure 2), is home to an active volcano, Mauna Loa, which has the potential of putting local populations at risk in the case of an eruption (Hawaii Center for Volcanology, 2015). In the last 150 years, Mauna Loa has erupted 33 times and twice, the lava flows have covered land that is now a part of Hilo, the most populated census-designated place (USGS). In areas with high population densities, lava flows are dangerous and destructive. This project aims to forecast potential lava flows in the most populated census blocks so …

Spread Of The Invasive Hemlock Woolly Adelgid, Zoe C. Dickerson, Joanna L. Keel

We created three maps using Arc GIS and projected them using the USA Contiguous Albers Equal Area Conic projected coordinate system. The first depicts the spread of the hemlock woolly adelgid since its introduction to the United States. The second shows areas that are most at risk to future spread according to a model we created. The final map serves to test our model for predicting future spread.

Distribution And Accessibility Of Public Green Space In Waterville, Me, Yue Yu, Ruofei Jia

Atlas of Maine

This project shows the distribution and accessibility of public green space in the city of Waterville, ME. Green space is important in urban areas because it encourages interaction between residents and nature, builds social ties, enhances spatial network, provides public spaces for recreation, and benefits physical and mental health. The city of Waterville does not have accurate GIS data that shows a complete network of green spaces in the city. A 2004 National Land Cover Database classifies areas with vegetation. Waterville city zoning data classifies the land into functional zones. However, previous to our project, the land cover and zoning …

The Farm In The City In The Recent Past: Thoughts On A More Inclusive Urban Historiography, Ruth Glasser

Urban and Community Studies Faculty Writing

The scholarly and journalistic literature usually treats urban agriculture as a new phenomenon, but it is a neglected dimension of urban history. Some U.S. cities, at least in the Northeast, had food-raising and processing practices not just in colonial times but right up until the relatively recent past. Three areas of history are explored that have mostly omitted discussion of city food production but nonetheless provide important frameworks to explore such production: urban development, agricultural, and immigrant history. Woven throughout this piece is evidence from a study of Waterbury, Connecticut. Local food production did not die when the Industrial Revolution …

Coral Bleaching And The Effect Of Disturbances On The Damselfish Community On Lizard Island, Australia, Alejandra Munoz

Independent Study Project (ISP) Collection

Coral reefs are characterized by their dynamic ecological processes that supports a high diversity through the recruitment of marine species and temporal disturbances that can have positive effects on the system. In the face of global climate change however, coral reefs face intense coral bleaching and increased degradation as they may begin to have less time to recover between bleaching events in the near future. Little is known on the long term effects of coral bleaching and habitat degradation on reef fish communities and much less is known about the mechanisms that bring about changes to reef fish assemblages.

Reframing Communication About Zika And Mosquitoes To Increase Disease Prevention Behavior, Amanda E. Sorensen, Rebecca C. Jordan, Shannon Ladeau

School of Natural Resources: Faculty Publications

Emergence of invasive vector species and the diseases they carry present a clear danger to the public as well as a challenge for scientists and experts to control effectively. Given the urgent need to address this phenomenon, we suggest that desired public action toward these invasive vectors can be motivated through intentional framing in science communication. In this paper, we sought to evaluate the effect of framing about ZIKV (Zika virus) on reported willingness to comply with mosquito prevention action. Post framing intervention, we found a significant increase (N = 26, p < 0.001) in individuals willing to take preventative action against mosquitoes. By methodically investigating best communication practices, this study and others can help practitioners mobilize communities to address large-scale ecological problems. Additionally, the principles outlined here may be transferrable to other communication efforts about ecological issues outside of ZIKV and mosquitoes.

Exploring Alternative Funding Methods For The Lead Remediation Program In Scott County, Iowa, Brittany A. Poynor, Layne Porembski, Arielle Bloemer, Brandon Schattner, Sarah Hanson

2016-2017: Scott County, Iowa and the Scott County Health Department

For this project, five students worked to put together five alternative funding solutions for the Scott County Health Department's lead remediation program. With limited government grants available, the health department is now considering local funding in order to address the issue of lead poisoning in Davenport, Iowa. These reports, along with other SWLI research, provide valuable information and are the foundation of the up-and-coming remediation program for the county.

How Do Communities Proactively Address Lead Remediation? Community Case Studies From Iowa, Emma Nordmeyer

2016-2017: Scott County, Iowa and the Scott County Health Department

Scott County Health Department officials reached out to the Sustainable Working Landscapes Initiative (SWLI) program at Augustana College to start a partnership to address environmental issues related to lead hazards in Scott County homes. Students in Fall 2016 Contemporary Social Issues class worked in teams to perform case studies on communities in Iowa that address lead remediation proactively. Teams of students studied Dubuque, Linn, Polk, Marshall, and Black Hawk counties in Iowa. The students worked to identify obstacles, successes, key questions, and recommendations for future directions in lead remediation from these communities. This report is a summary of those findings.

A Multicriteria Decision Analysis For Identifying Priority Conservation Areas For Grassland Birds, Flavio Sutti, Allan Strong, Noah G. Perlut

Environmental Studies Faculty Publications

Biodiversity conservation frequently competes with the needs of society for agricultural production and development. However, properly designed and efficiently implemented conservation programs can be used to integrate wildlife and human needs. We tested the efficacy of multicriteria decision analysis as a tool to select priority areas for conservation in human-dominated landscapes using grassland birds in the northeastern US as a test case. We created detailed GIS layers including landscape- (forest, grassland, development, and roads within a 3000-m buffer around each grassland patch) and patch-level (size, management, and conservation status) criteria important in grassland bird habitat selection and conservation. We developed …

Characterization Of Legacy Sediment Variations In Accretion And Carbon Dynamics Following Dam Removal In A Recently Restored Tidal Freshwater Wetland, Melissa J. Davis, Christopher D. Gatens, Edward R. Crawford, Arif Sikder

Rice Rivers Center Research Symposium

Damming disrupts the natural flow of sediment to adjoining water bodies resulting in the accumulation of Legacy Sediments (LS). While the impact of LS inputs has been well investigated in lotic Mid-Atlantic piedmont stream restorations, (i.e. milldam removal 1,2,3,4,5,), there have been few studies investigating LS following dam removal in low-gradient coastal plain streams. The objectives of this study were to quantify spatial and temporal variations of LS characteristics in a low-gradient tidal stream restoration within the lower James River watershed. Secondary objectives were to assess the current temporal and spatial variability in sediment deposition within the recently restored Kimages …

Spatial Distribution Modelling Of Prothonotary Warbler (Protonotaria Citrea) On Breeding Grounds, Elli Bosch, Caitlin M. Vigneau, Rolang Piocuda, Catherine Viverette, Jessica Reese

Rice Rivers Center Research Symposium

Ecological niche modeling is used to predict a species’ distribution in a geographic area based on abiotic and biotic variables. Understanding a species’ range is important for conservation and restoration efforts. As anthropogenic forces may alter or deplete habitat, it is important to know the ecological requirements of a species to understand how and what habitat to protect. With the increasing threat of climate change and rising temperature and precipitation, the suitable habitat and the distribution for many species is expected to shift. Migratory species are particularly at risk of these changes as they require suitable habitat not only on …

Offspring Sex Ratio In Double Brooding Prothonotary Warblers, Radleigh Herschel, Anthony G. Kouri, Rebecca Vareed, Stephanie Warshawsky, Matthew Desaix

Rice Rivers Center Research Symposium

Prothonotary warblers are bright, golden birds who, with their loud calls, make themselves known in wetland habitats in the spring after returning from their winter homes in the Neotropics to breed. This migratory species is important to study because of their need for these habitats and are declining in population due to the degradation of wetland environments across the western hemisphere.

VCU started a project in 1987 to study prothonotary warblers including population genetics, breeding biology, and migration ecology. Since then, with the help of Richmond Audubon Society, the project has erected over 600 nesting boxes along the James River …

Projecting Habitat Of The Nonbreeding Prothonotary Warbler (Protonotaria Citrea) Under Various Climate Scenarios, Hannah Byrne, Lindsey Flanary, Ernesto Gagarin, Jessica A. Reese, Catherine B. Viverette

Rice Rivers Center Research Symposium

Understanding a species’ range, and how it may change over time, allows researchers to develop more robust species management plans and to identify vital habitat for conservation planning. For migratory bird species, different habitats are utilized during different times of year. While a neotropical migratory species’ breeding grounds may be adequate, its wintering ground or various stopover areas may be under threat. In what is known as a carry over effect, the degradation of wintering grounds can lead to poor quality individuals in the breeding range (Rockwell et al., 2012), thus reduced fitness.

The tropics are predicted to experience changes …

The Effects Of Inorganic Nitrogen And Phosphorus Enrichment On Herbaceous Species Growth Of The Kimages Creek Wetland (Va), Kristen Burton, Scott C. Neubauer

Rice Rivers Center Research Symposium

Dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) infiltrate waterways through fertilizer application, urban stormwater runoff, and sewer infrastructure leaks. As surrounding waterbodies experience increased DIN and DIP inputs, wetlands can experience corresponding nutrient enrichment. Vegetation uses DIN and DIP for structural growth, color, and seed production. Changes in DIN and DIP availability can influence species distribution due to differences in photosynthetic rates, root morphology and structure, and tissue type.

DIP and DIN inputs are projected to increase 15-30% and 30-60% in the next fifty years¹. It is of interest to examine plant growth characteristics within this nutrient enrichment …
