Diversity And Habitat Use Of Bats In Modified Suburban Landscapes, Brittany Morgera
Diversity And Habitat Use Of Bats In Modified Suburban Landscapes, Brittany Morgera
Biology Presentations
Bats occupy critical ecological niches and perform important ecosystem services like controlling insect populations. However, humans have altered bat habitat substantially, resulting in the reduction of bat populations. The goals of this research are to assess bat diversity and habitat use across different levels of suburban habitat modification. To accomplish this, we deployed passive acoustic recorders at twelve locations with varying human impact in Montgomery County, Pennsylvania. In accordance with The North American Bat Monitoring Program’s standards, acoustic analysis software was used to identify bat species. Manual identification methods from The Canadian Wildlife Health Cooperative were used to verify these …
Depth Patterns Of Redear Sunfish Lepomis Microlophus In Kentucky Lake, Justin Graben
Depth Patterns Of Redear Sunfish Lepomis Microlophus In Kentucky Lake, Justin Graben
Scholars Week
Redear Sunfish Lepomis microlophus are a highly sought sportfish known for their size potential, but their ecological behavior in large reservoirs remain poorly understood. In this study, we looked at how Redear Sunfish Lepomis microlophus move vertically in Kentucky Lake. We used acoustic tags with depth sensors to measure the movement of Redear Sunfish both diurnally and seasonally within Kentucky Lake.
During the day, Redear Sunfish occupied significantly deeper waters compared to dawn, dusk, and night (p < 0.0001.). Many fish, including the species in the Lepomis genus, may have a preference for specific light levels for optimal foraging and predation avoidance, even if predation is not the primary concern at larger sizes. This daily pattern was consistent through most seasons, except on average the fish were deeper during the winter season (p < 0.0001).
Understanding the movement patterns of Redear Sunfish is essential for effective species management, especially as their popularity grows and they potentially compete with …
International Energy Geopolitics, Bert Chapman
International Energy Geopolitics, Bert Chapman
Libraries Faculty and Staff Presentations
Overview of international energy geopolitical trends. Emphasizes the importance of the Persian Gulf, South China Sea, East China Sea, Russia, and the Arctic to U.S. and international economic and strategic developments. Stresses the continuing importance of fossil fuels in domestic and international energy consumption, the variety of energy sources being used by various global regions, the potential for military conflict over access to natural resources, and how emerging energy leaders will determine global energy, environmental, and international security developments.
A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer
A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer
Student Scholar Showcase
The current dilemma of College Lake offers a unique case study for how urban ecosystems can not only subsist within cities but provide pivotal functions for them as well. With the potential for a dam-breaching storm event increasing in possibility with each passing year, concerns regarding the structural integrity of the College Lake dam in Lynchburg, VA have arisen. Such concerns have led the City of Lynchburg to consider reinforcement or removal of the dam in order to mitigate flood risks along the Blackwater Creek floodplain. Since its formation following the installation of the Depression-era dam, however, College Lake has …

Fostering Multicultural Competence and Global Justice: an SIT Symposium
In addition to my work coordinating the SIT study abroad program Amazon Resource Management and Human Ecology since 1998, I pursue personal interests in the relation of modern development projects and the social environmental conditions faced by local populations of the region. In 2005, I evaluated the environmental licensing and implementation of Alcoa´s (Aluminum Company of America) mine operation in Juruti, western Pará State, which started operation in 2009. I was invited by the communities impacted and the different actors involved to participate in the team in charge of developing methodologies to valuate the social-environmental externalities faced by the communities, …
