Reproductive Success Of A Neotropical Migratory Songbird In Response To A Changing Climate, Ashley Grupenhoff, Lesley Bulluck Jan 2016

Reproductive Success Of A Neotropical Migratory Songbird In Response To A Changing Climate, Ashley Grupenhoff, Lesley Bulluck

Undergraduate Research Posters

Climate change is of rising concern especially due to how and if this changing climate affects individual species and their fitness. Migratory species, especially long-distance migrants, are ideal models for exploring the relationship between warming temperatures on temperate breeding grounds and decreased precipitation on tropical wintering areas. Few studies have long term data sets to observe species-specific assessments of fitness in relation to changing precipitation and temperature patterns, and those that have assessed these relationships show inconsistent results. We analyzed long-term data of a neo-tropical migratory songbird (Protonotaria citrea) to assess the potential relationships between indices of reproductive …

3d Tool Evaluation And Workflow For An Ecological Approach To Visualizing Ancient Socio-Environmental Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto, Shona Sanford-Long, Jack Kerby-Miller Jan 2016

3d Tool Evaluation And Workflow For An Ecological Approach To Visualizing Ancient Socio-Environmental Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto, Shona Sanford-Long, Jack Kerby-Miller

Department of Anthropology: Faculty Publications

Architectural reconstructions are the centerpieces of ancient landscape visualization. When present, vegetation is relegated to the background, resulting in underutilized plant data—an integral data source for archaeological interpretation—thus limiting the capacity to take advantage of 3D visualization for studying ancient socio-environmental dynamics. Our long-term objective is to develop methods of 3D landscape visualization that have value for examining changes in land use and settlement patterns. To begin to work toward this objective, we have (1) identified 3D tools and techniques for vegetation modeling and landscape visualization, (2) evaluated the pros and cons of these tools, (3) investigated biological and ecological …

Affective Responses In The Purchase Of Consumer Eco Products, Alma Maria Jennifer A. Gutierrez, Rosemary R. Seva Jan 2016

Affective Responses In The Purchase Of Consumer Eco Products, Alma Maria Jennifer A. Gutierrez, Rosemary R. Seva

DLSU Business & Economics Review

This study aims to investigate the affective attachment of consumers to ecological products. It also aims to determine the type of emotions elicited by these kinds of consumer products. It was hypothesized that buying eco products can elicit different kinds of emotions in consumers. These emotions are usually positive that cause attraction to consumers and eventually the actual purchase of the product. An exploratory pre-purchase affect survey was conducted through field and online survey to determine what shoppers feel while looking for eco products to buy. Results revealed that participants significantly experience more positive feelings/emotions than negative feelings/ emotions when …

Socioeconomic And Environmental Assessment Of Woody Biofuels In Southern United States, Bernabas T. Wolde Jan 2016

Socioeconomic And Environmental Assessment Of Woody Biofuels In Southern United States, Bernabas T. Wolde

Theses, Dissertations and Culminating Projects

Although the emergence of woody bioenergy offers several energy, economic, social, and environmental benefits, forestland owners’ willingness to participate in a biomass supply market, how it affects land use choices, and forestland owners’ sustainability concerns are not well understood. In addition to these gaps, how much residual biomass forestland owners are willing to retain on site for soil fertility and other environmental benefit purposes and forestland owners’ tendency to enroll in public incentive programs are not fully documented. Because private forestland owners manage two thirds of the 214 million acres of forest cover in the southern United States, understanding their …

Green Remediation Of Acid Mine Drainage (Amd)-Impacted Soil And Water, Abhishek Roychowdhury Jan 2016

Green Remediation Of Acid Mine Drainage (Amd)-Impacted Soil And Water, Abhishek Roychowdhury

Theses, Dissertations and Culminating Projects

Although mining industries such as coal and minerals generate revenue, they are responsible for a number of negative environmental consequences, and the production of acid mine drainage (AMD) and acid sulfate soil are the most concerning among them. Current AMD management practices are expensive, ineffective, or unsustainable. This study evaluated the potential of a cost-effective and environment-friendly “green” technology in treating AMD-impacted water and soil that utilizes the metal-binding and acid-neutralizing capacity of an industrial by-product, namely drinking-water treatment residuals (WTRs) and the extensive root system of a metal hyper-accumulating, fastgrowing, non-invasive, high biomass perennial grass, vetiver (Chrysopopgon zizanioides …
