Designing A Green Graduation At Colby College, Alaina J. Clark
Designing A Green Graduation At Colby College, Alaina J. Clark
Honors Theses
Lately, there has been a growing trend of “green” events. The increase in understanding and discussions about the future climate has caused people throughout the world to become concerned about their contribution to climate change. This is true in the Northeast United States as well. Many New England colleges and universities, including Colby College in Waterville, Maine, are becoming leaders in climate change mitigation. As a teaching institution, Colby has recognized that public education is an important part of the solution to the climate crisis. Colby also understands that commencement weekend is an ideal opportunity for climate change education. As …
Hydrologic And Water Quality Assessment Of Miller Run: A Study Of Bucknell University’S Impact, Alison C. Schaffer
Hydrologic And Water Quality Assessment Of Miller Run: A Study Of Bucknell University’S Impact, Alison C. Schaffer
Honors Theses
Human development causes degradation of stream ecosystems due to impacts on channel morphology, hydrology, and water quality. Urbanization, the second leading cause of stream impairment, increases the amount of impervious surface cover, thus reducing infiltration and increasing surface runoff of precipitation, which ultimately affects stream hydrologic process and aquatic biodiversity. The main objective of this study was to assess the overall health of Miller Run, a small tributary of the Bull Run and Susquehanna River watersheds, through an integrative hydrologic and water quality approach in order to determine the degree of Bucknell University’s impact on the stream. Hydrologic conditions, including …
The Effect Of Orientation To Growing Season Sunlight On Stomatal Parameters Of Q. Rubra In The Belgrade Lakes Region, Central Maine, Rachel G. Daly
The Effect Of Orientation To Growing Season Sunlight On Stomatal Parameters Of Q. Rubra In The Belgrade Lakes Region, Central Maine, Rachel G. Daly
Honors Theses
Stomatal frequencies of fossil-plant species are used to estimate past pCO2 levels based on the physiological functions of living taxa. Numerous studies have shown that there is an inverse relationship between pCO2 and stomatal frequency parameters. As levels of pCO2 increase, the Stomatal Density (SD) and Stomatal Index (SI) decrease. However, pCO2 is not the only factor affecting SD and SI values, which are a product of leaf growth and expansion. Stomatal characteristics differ between genera, and studies also have shown that SD and light intensity have a positive correlation. The present study hypothesizes that SD and SI are not …
Separating People And Wildlife: Zoning As A Conservation Strategy For Large Carnivores, Courtney L. Larson
Separating People And Wildlife: Zoning As A Conservation Strategy For Large Carnivores, Courtney L. Larson
Honors Theses
Large carnivores are some of the world’s most difficult species to conserve because of their large spatial requirements, low population density, and high potential for conflict with humans. However, large carnivores are valuable for ecological, cultural, and ethical reasons. Carnivore management can take a wide variety of forms, including translocation, sterilization, livestock compensation programs, regulated hunting, improved livestock husbandry practices, and zoning, among others. The objective of this thesis was to conduct a comparative analysis of examples of zoning from around the world to examine whether it is an effective carnivore management strategy.
Analysis of twelve case studies showed that …
Carbon Neutrality At Colby College, Jamie K. O’Connell
Carbon Neutrality At Colby College, Jamie K. O’Connell
Honors Theses
Carbon neutral is a term used to describe any organization, entity, or process that has a net greenhouse gas (GHG) emissions level of zero (Dautremont-Smith et al. 2007a). Since carbon neutrality only requires a net greenhouse gas emissions level of zero, organizations do not need to eliminate all carbon pollution to become carbon neutral. Net emissions differ from gross emissions in that gross emissions are the sum of all emissions released by the individual or entity, whereas net emissions are equivalent to the gross emissions minus any carbon offsets. A carbon offset is any activity that reduces carbon emissions so …
Effect Of Observed Biological And Non-Biological Movement On Human Action And Coordination, Walter L. Campbell
Effect Of Observed Biological And Non-Biological Movement On Human Action And Coordination, Walter L. Campbell
Honors Theses
Recently, it has been demonstrated that an individual’s rhythmic limb movements exhibit greater variability when viewing spatially incongruent biological limb movements, but not when viewing spatially incongruent non-biological movements. Some researchers have concluded that a ‘mirror-neuron system’ might mediate the intrinsic bidirectional link between perception and action underlying interpersonal, but not environmental, coordination (e.g., Kilner et al., 2003; Tognoli et al., 2007). The current study aimed to: 1) contest this recent finding; and 2) demonstrate that the self-organized entrainment processes of coupled oscillators can explain the differing influences of biological and non-biological movements. In the first experiment, participants intentionally coordinated …
Phosphorus Primer For Maine’S Lakes, Lindsay B. Philips
Phosphorus Primer For Maine’S Lakes, Lindsay B. Philips
Honors Theses
Phosphorus plays a major role in aquatic systems and the life that they support. It is a macronutrient that constitutes 0.5lf microorganisms and zooplankton by mass. Phosphorus is of great importance in terrestrial, agricultural, and plant systems as a macronutrient, and when it comes to aquatic systems, we tend to look at phosphorus in terms of its influence on lake primary productivity. Lakes are often phosphorus sinks because they are maintained by hydrological sources that are capable of causing nutrient influx. To understand phosphorus cycling in lake systems, it is important to consider the many sources and forms of phosphorus …
Developing A Tool To Assess Human Health Impacts Of Purchasing, Kaitlin C. Himmelmann
Developing A Tool To Assess Human Health Impacts Of Purchasing, Kaitlin C. Himmelmann
Honors Theses
Chemical production impacts the environment and human health. Many common products contain chemicals that can be detrimental to human health and more specifically harmful to the endocrine system. Many individuals and institutions unknowingly buy products containing chemicals that can harm the endocrine system. I developed a score that examines the level of harm that these chemicals pose to the endocrine health of the general population. The implications of Colby’s purchasing practices are discussed.
Patterns Of Dorm Energy Use And Potential Opportunities For Dorm Energy Conservation At Colby College, Sarah Kelly
Patterns Of Dorm Energy Use And Potential Opportunities For Dorm Energy Conservation At Colby College, Sarah Kelly
Honors Theses
This thesis research began in the fall; around the same time President Adams predicted that the school would pay one million dollars more than budgeted this academic year on energy due to the rising energy prices (Adams, pers. comm.). Students, their families, and the college would bear this monetary burden. Solutions that lower energy costs would benefit many different parties. Dorms use a large amount of energy. Unlike many energy demands on campus that are relatively constant, dorm rooms are flexible in their energy use because students can change their energy use patterns. Many areas of energy waste characterize dorm …

Macrofungi Of The Tennessee River Gorge, William D. Starrett
Macrofungi Of The Tennessee River Gorge, William D. Starrett
Honors Theses
Representative macro fungi of the Tennessee River Gorge were collected on the Tennessee River Gorge Trust (TRGT) property during 18 forays I conducted fom May to November 2004. This dramatically added to the baseline data on the macrofungi of the TRGT by adding 15 orders, 34 families, and 138 species to the existing list. These data were recorded in the herbarium of the University of Tennessee at Chattanooga database. I converted the University's File Maker Pro fungi database into Microsoft Excel and Access, which allows it to be processed for introduction into the National Biological Information Infrastructure and onto the …
Role Of Private Owners In The Conservation Of Exotic Species, Jessica L. Beetz
Role Of Private Owners In The Conservation Of Exotic Species, Jessica L. Beetz
Honors Theses
This study examines the private ownership of exotic species, a topic very relevant to conservation that has long been ignored in the public sphere of policy and discussion. The private ownership of exotic species is a multifaceted issue that affects not only conservation, but also the domestic industry, world trade and education. The volume of trade in live animals is remarkably high and growing, making studies that investigate the implications of this trade on the endangered and threatened species even more pressing. This thesis investigates whether or not animal species held in captivity by private owners benefit conservation of their …

Honors Theses
The Forest Service manages land for a diverse array of purposes under the Multiple Use Doctrine. Many of these uses are incompatible and lead to conflict The goal of my research is to explain what guides the Forest Service's management decisions, since this is critical to understanding how conflicts are resolved, .and uncover alternative approaches that better protect the environment.
In this paper, I present a brief history of the Forest Service's management over the past century. Particular attention is given to explaining trends in timber and recreation management. Following the historical presentation, I attempt to identify a set of …
Estimating The Impact Of State Policy Incentives On Wind Power Development, Kellie K. Phelan
Estimating The Impact Of State Policy Incentives On Wind Power Development, Kellie K. Phelan
Honors Theses
Wind power has recently become a viable alternative to conventional fossil fuels for electricity generation because of decreasing costs and the presence of various supportive policy incentives. Pressing environmental issues and concerns about energy security have also prompted interest in wind power as an alternative fuel source. Though less than one percent of the United States electricity supply currently comes from wind power, state policy incentives have the potential to promote the development of the significant wind resources found throughout the United States (American Wind Energy Association 2003). Using a large data set that combines information on installed wind capacity …
Improving The Campus Sustainability Assessment Process, Andrew Nixon
Improving The Campus Sustainability Assessment Process, Andrew Nixon
Honors Theses
The human enterprise is rapidly overwhelming the Earth’s ecological systems and draining its natural resources. According to Vitousek et al., as much as one-half of the planet’s land surface has been transformed by human activity; more than half of the world’s available fresh water is used by humans; and a quarter of the planet’s bird species have been driven to extinction by human activity (Vitousek et al, 1997). These and many other negative trends pose catastrophic implications for the future of our species and for the planet’s other inhabitants.
Local Participation As A Determinant Of Success In World Bank Environmental Projects: What Is The Evidence?, Catherine Benson
Local Participation As A Determinant Of Success In World Bank Environmental Projects: What Is The Evidence?, Catherine Benson
Honors Theses
The current impoverished, environmentally degraded state of Africa suggests that international aid projects have proven largely unsuccessful in tackling the enormous development and environment challenges faced by Africa. Africa has historically been inundated with groups trying to implement change in the form of political, economic, and environmental agendas, beginning in the colonial period and continuing today. The abundance of advice and financial assistance poured into this region have resulted in a continent lagging behind other developing regions to an even worse extent than prior to aid projects. The environment of development in Africa is complex; nowhere else in the world …

"Leadership And Peace And Conflict Studies" : The Mutual Benefits Of Linking Multidisciplinary Fields Of Study, Douglas M. Schaefer
Honors Theses
The purpose of this project is to take two fields of study, Leadership Studies and Peace and Conflict Studies (a.k.a. Peace Studies), and critically analyze how both can mutually benefit each other. For this purpose, a proposed model of an academic course combining the two fields of study in the form of a conceptual syllabus will be included in the appendix. However, before such a course is taught, the connections between two previously unconnected fields must be made. This paper will show how both fields of study mutually benefit each other and combine to form a course designed specifically for …

Public Policy Issues, Aaron J. Heffron
Public Policy Issues, Aaron J. Heffron
Honors Theses
The following pages are a collection of three case studies assembled with the intent to facilitate discussion about key leadership issues related to the public policy realm. Critics of leadership studies have often posted to the theoretical nature o the discipline to criticize the worth. One method to teach leadership is the utilization of case studies, or "real world" examples. If your position is that leadership can only be taught through practical experience, these case studies should present an interesting exercise. They seek to inculcate the idealistic world of theoretical studies with doses of realistic situations.
For these case studies …
Use Of Economic Instruments In Biodiversity Conservation Projects: The Sustainability Of Projects In The Ecuadorian Amazon, Amy Lyons
Honors Theses
Under what conditions do biodiversity conservation projects that use economic incentives promote the most significant and sustainable biodiversity protection? The study of how nations can best invest their resources to promote conservation while simultaneously encouraging a sustainable form of economic development has recently become a major focus for ecologically rich, less-developed countries. There have been many innovative and successful attempts at combining biodiversity protection with economic development, and others that have done more harm than good. Since there is no guaranteed recipe for a successful project, it is crucial to examine projects in detail to discern which type of project …
