What Components Influence Hypothetical Willingness To Pay For The Environmental Benefits Of Shade-Grown Coffee?, Ellen V. Webb
DePaul Discoveries
Coffee is one example of a good whose consumption can lead to environmental degradation that the consumer is unaware of. During the 19th century, new high-yield varieties of coffee were developed that could be grown under the direct sunlight of recently deforested areas. An ecologically friendly alternative to mass-produced sun-grown systems is shade-grown coffee. This coffee is grown under traditional forest cover, providing ecological benefits such as species habitat, but at lower yields. In the global market, a price premium is the practice of placing a higher price than the market price on a specific good. If consumers value …
How Do Management Treatments Affect Invasive Cattail (Typha X Glauca) And Pore Water Nutrient Concentrations?, Yarency Rodriguez
How Do Management Treatments Affect Invasive Cattail (Typha X Glauca) And Pore Water Nutrient Concentrations?, Yarency Rodriguez

Invasive species are problematic for wetland managers, but little is known about how common management treatments influence nutrient cycling or plant responses. This study tested three experimental treatments (mowing, herbiciding, and harvesting (i.e., removal of aboveground biomass)) on several response variables: wetland soil porewater nutrient content (NO3-, NH4+, PO4-), native plant and invasive-Typha density, and light attenuation through the plant canopy. Seventeen days post-treatment, herbiciding resulted in higher porewater phosphate concentrations (55.63 µg-P/L) than harvesting (8.95 µg-P/L). After 24 days, herbicide had higher porewater phosphate concentration (72.03 µg-P/L) than all …

Over the past few decades environmental awareness and education have increased without a corresponding increase in pro-environmental behavior. Recent research on public service announcements and social marketing theory indicate that positive injunctive with positive descriptive norms are most effective in increasing proenvironmental behavior. The current study focused on the impact of different types of environmental messages on promoting recycling behavior in college students. Over 250 recycling actions were measured in the experiment. It was hypothesized that the positive injunctive with positive descriptive statement would be most effective in causing more university students to recycle. The findings, although not statistically significant, …
