Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman Dec 2017

Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman

The Kennesaw Journal of Undergraduate Research

The Chattahoochee Nature Center (CNC) is one of the leading educational centers in Georgia about the ecology of the Chattahoochee River. Due to lack of man power, keeping down the weeds in the CNC plant nursery is one of those tasks that often gets left undone. The nursery becomes overgrown with invasive weed species. Understandably, they must sometimes resort to the use of herbicides, such as Roundup®, to keep the hundreds of native and endangered species of plants housed at CNC from being choked out by invasive weeds. This study tests the ability to suppress weed growth by use of …


Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook Sep 2017

Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook

Georgia Journal of Science

Coastal grasslands are globally threatened by development and natural succession. In the southeastern United States, these increasingly rare ecosystems are being managed using prescribed fire, but ecological responses to fire management are largely unknown, particularly among nontargeted species. We tested for short-term effects of controlled burning on the abundance and species richness of adult butterflies, which utilize coastal grasslands for nectaring resources and as migratory stopover sites. In February 2015, four plots of coastal grassland on Little St. Simons Island, GA were burned and paired with unburned (control) plots of equal size. Throughout the following summer-fall flight season, we conducted …


The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez Jul 2017

The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez

Journal of Environmental and Resource Economics at Colby

This paper seeks to figure out the effect weather has on individuals’ behavior. A more focused approach to determining this effect is seeing how different weather conditions ranging from the temperature, the precipitation, the amount of inches of snowfall and the wind speed effect the ridership of Citi Bikes throughout all four seasons. The approach of this research paper is using data from the National Climatic Data Center that focuses in on the weather found in Manhattan, New York and correlates each of the weather conditions to the total number of trips per day that is provided by the Citi …


Electricity Demand Due To Policy Change In The U.K., Kevin W. Doherty Jul 2017

Electricity Demand Due To Policy Change In The U.K., Kevin W. Doherty

Journal of Environmental and Resource Economics at Colby

This paper examines United Kingdom Electricity Demand with regards to the Climate Change Act, which was enacted in November of 2008. Through actual demand data obtained from Nationalgrid, a U.K. based gas and electric utility company, this paper seeks to find out if the Climate Change Act has started to achieve its goal of reducing carbon emissions by looking at trends of electricity demand. Burning fossil fuels to produce electricity is a major contributor to global warming in the U.K. and policies enacted do not always live up to their ultimate goals. This paper tests how on track the Climate …


The Demographic Drivers Of California’S Environmental Voting, Lukas Yasuda Jul 2017

The Demographic Drivers Of California’S Environmental Voting, Lukas Yasuda

Journal of Environmental and Resource Economics at Colby

This study examines the demographics of California’s 53 congressional districts and the relationship with the voting patterns on three environmentally focused propositions in the 2008 and 2010 elections. Previous literature on the topic is mixed as some studies suggest that select attributes are found among environmental voting centers, yet other research describes the relationship as more complex than simple characteristics. Previous literature on the topic is mixed, with some studies suggesting that select attributes are found among environmental vote support hubs, whereas alternative research suggests the problem is more complex than simple characteristics. I collected data on income, education, age, …


The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney Jul 2017

The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney

Journal of Environmental and Resource Economics at Colby

Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the …

Nitrogen Sustainability: Impediments To Action And Communication, Eric E. Jorgensen Jan 2017

Nitrogen Sustainability: Impediments To Action And Communication, Eric E. Jorgensen

Journal of Environmental Sustainability

“Sustainability” is widely used to imply the presence of explicit consideration of environmentally friendly needs and that high societal-value is placed on those needs. However, it is abundantly clear after 30 years that talking about sustainability and achieving it are two entirely different things. The core concept underlying sustainability is that current human practices and activities be conducted so as to not degrade prospects for future generations. With nitrogen, conflicts about sustainability in-theory and sustainability in-practice are close to the surface because of nitrogen’s central role in food production and economic activity. Measures of nitrogen inputs commonly range as high …
