Energy-use Behavior Among College Students

O'Connell, Lillian 01 January 2010 (has links)
As the effects of global climate change become increasingly apparent, many concerned individuals are making efforts to reduce their greenhouse gas emissions. One simple and effective method of reducing one's personal carbon footprint is through energy conservation behavior. Studies have shown that occupant behavior can control as much as 50% of residential energy use and that energy use varies widely between residences with the same number of occupants depending on consumption behavior. In light of this, energy conservation behavior is a valuable method of reducing greenhouse gas emissions and curbing the effects of climate change. Motivating people to conserve energy could have profound positive effects on the environment. The following study applies Icek Ajzen's Theory of Planned Behavior (1991) to energy conservation behavior among college students in the state of Florida. This research tests the hypothesis that pro-environmental attitudes, influence of peers, and a high level of perceived control over behavior have a significant impact on energy conservation behavior.

Behavior and conservation: hellbender reproductive behavioral responses to poor water quality and the value of private lands research for conservation outreach

O'Brien, Rebecca Sarah 01 September 2023 (has links)
The behavior of humans and animals is an important component of conservation. The way people behave can cause environmental harm, but it also can be a solution to conservation challenges. Similarly, wildlife can respond to changing environments in ways that are detrimental to their survival, but they can also in some cases adapt or even thrive in human-impacted environments. In this dissertation, I discuss the ways in which human and hellbender behaviors relate to conservation. First, using survey and interview data, I explore the reasons why private landowners allow access to their property for research. I find that landowners are more likely to allow research on their property if they have previously allowed research, if they are interested in learning about the research taking place, if they have larger properties, and if they had positive attitudes towards conservation. Conversely, they are less likely to allow access to their property if they are concerned that doing so might restrict free use of their property. Other possible predictors that I investigate, such as landowner demographics, landowner trust in science, and landowner attitudes towards hellbenders are not significant predictors of allowing research. I next explore the effects of engaging landowners in research either via citizen science or "traditional" private lands research where scientists work on the landowner's property, but the landowner is not involved in data collection. I assess the effects of these types of engagement on landowner conservation knowledge, attitudes, awareness, and behavioral intentions and compare the effects across these two treatment groups and a control. I find similar changes in both the traditional and citizen science treatment groups, with involvement in the research leading to greater conservation knowledge, increased awareness of conservation concerns, more positive attitudes towards conservation, and/or more conservation behavioral intentions. However, I observe limited behavior change in any treatment group, and I identify a lack of efficacy and a hesitancy to accept responsibility for water quality degradation as possible barriers to behavior change. My investigations of animal behavior utilize custom-built underwater infrared camera technology to study hellbender reproductive behavior. I first add to current understanding of hellbender breeding behavior by describing the basic hellbender mating sequence, identifying the presence of potential alternative mating tactics, and describing two novel behaviors, including possible signal production via wave-based communication and a unique egg laying behavior by female hellbenders. I then measure the extent to which hellbender males (which provide the parental care) may help protect their offspring from low oxygen and high siltation, and I assess the possibility of trade-offs between parental care behaviors that benefit the eggs and self-maintenance behaviors that benefit the parent. I find that guarding male hellbenders increase both their parental care behaviors and their self-maintenance behaviors in response to low dissolved oxygen, but that they also show evidence of a trade-off between the two, with males ceasing parental care in favor of self-maintenance at sufficiently low levels of dissolved oxygen. Males show no parental response to high levels of silt. My findings add to our understanding of human and animal behavior and highlight the importance of behavioral flexibility to conservation. I find that hellbenders can to some extent modify their behaviors to compensate for the impacts of poor stream management on their own and their offspring's health, and I find that engaging landowners in research can encourage changes in awareness, attitudes, and behavioral intentions regarding conservation. / Doctor of Philosophy / The behavior of humans and animals is an important component of conservation.

I assess the effects of these types of engagement on landowner conservation knowledge, attitudes, awareness, and planned actions and compare the effects across these two treatment groups and a control. I find similar changes in both the traditional and citizen science treatment groups, with involvement in the research leading to greater conservation knowledge, increased awareness of conservation concerns, more positive attitudes towards conservation, and/or more conservation planned actions. However, I observe limited behavior change in any treatment group, and I identify a lack of perceived ability to make a difference among landowners and a hesitancy to accept responsibility for water quality decline as possible barriers to behavior change. My investigations of animal behavior use custom-built underwater night-vision cameras to study hellbender baby-making. I first add to current understanding of hellbender breeding behavior by describing basic hellbender mating activities, identifying the possibility that some males sneak into other male's nests to mate, and describing two new behaviors, including possible signal production via sound or vibration and a unique egg laying behavior by female hellbenders. I then measure how much hellbender males (which provide the parental care) may help protect their eggs from low oxygen and high dissolved dirt, and I assess the possibility of trade-offs between parental care behaviors that benefit the eggs and self-maintenance behaviors that benefit the parent. I find that guarding male hellbenders increase both their parental care behaviors and their self-maintenance behaviors in response to low dissolved oxygen, but that they also show evidence of a trade-off between the two, with males stopping parental care in favor of self-maintenance at low levels of dissolved oxygen. Males show no parental response to high levels of dissolved dirt. My findings add to our understanding of human and animal behavior and highlight the importance of behavioral flexibility to conservation. I find that hellbenders can to some extent change their behaviors to compensate for the impacts of poor stream management on their own and their children's health, and I find that engaging landowners in research can encourage changes in awareness, attitudes, and planned behaviors regarding conservation.

Expanding Audience Engagement with State Wildlife Agencies: Strategies for Supporting Diverse Participation

Jennings, Kelsey Kathleen 03 May 2024 (has links)
State fish and wildlife agencies are increasingly expected to meet accelerating wildlife conservation needs while addressing systemic problems that limit who has historically been able to access wildlife and conservation. To effectively address both of these needs, agencies need to better understand their constituencies, including both long-standing supporters and those who have been historically excluded. This thesis set out to achieve this through three chapters. (i) Using a nationwide panel survey, we sought to understand how patterns of wildlife viewing differ between Black, Indigenous, and people of color (BIPOC) and White viewers, as well as what most strongly supports this participation. We found that participation rates differ across ethnoracial groups, with most BIPOC viewers participating less than White viewers, especially around their homes. Additionally, BIPOC viewers indicated that social support was a key factor in encouraging participation. Finally, despite wildlife viewing being of similar or greater importance to BIPOC participants, they generally self-identified less as viewers, suggesting historic exclusion from wildlife viewing locales may impact contemporary participation. (ii) Through a questionnaire of Minnesotans engaged with the MN Department of Natural Resources and their Nongame Wildlife Program, we examined what most encourages donations and volunteer participation. The findings of this chapter suggest that donors had specific motivations, namely supporting biodiversity and conservation, whereas volunteer motivations were more varied, such as place-based preferences and access to conservation professionals. (iii) Using a series of focus groups with outdoor recreation and community science practitioners and participants, we aimed to understand what encouraged BIPOC Minnesotans to participate in nature-based community science programs. We found that participants rely on numerous forms of cultural capital to persist in community science, especially in inhospitable environments. Often, this included utilizing social relationships and continuing to participate despite negative interactions. Overall, this research contributes to a growing body of literature aiming to understand diverse engagement in wildlife viewing and nature-based community science, as well as general engagement with state agencies. By laying a foundation for sustainable engagement and support of diverse communities, particularly BIPOC groups, this thesis provides insights and recommendations for fostering equitable conservation practices in an era of environmental change and social evolution. / Master of Science / North America and the world are witnessing unprecedented environmental changes, including biodiversity loss, climate change, and urbanization, impacting both human and wildlife communities. Concurrently, shifts in public engagement with state wildlife agencies and outdoor recreation are evident, with historic constituencies of hunters and anglers declining, posing challenges to conservation efforts. To address these challenges, state agencies strive to understand and diversify their supporters. Against this backdrop, this thesis investigates wildlife viewing patterns among ethnoracial groups, constituent engagement with state wildlife agencies, and factors motivating participation in community science initiatives among Black, Indigenous, and people of color (BIPOC) communities. Using a nationwide survey of wildlife viewers, we found significant differences in participation, both around and away from home. We also found that social support from friends, family, mentors, and peers was associated with increased participation. Additionally, despite wildlife viewing being of similar or greater importance to BIPOC participants, they generally self-identified less as viewers, suggesting historic exclusion from wildlife viewing locales may impact contemporary participation. Through a questionnaire of Minnesotans engaged with the MN Department of Natural Resources and their Nongame Wildlife Program, we examined what most encourages donations and volunteer participation. The findings of this chapter suggested that donors had specific motivations, namely supporting biodiversity and conservation, whereas volunteer motivations were more varied, such as place-based preferences and access to conservation professionals. Finally, using a series of focus groups with outdoor recreation and community science practitioners and participants, we aimed to understand what encouraged BIPOC Minnesotans to participate in nature-based community science programs. Our results suggested that social support, community-specific and community-led programs, and programs co-produced with community groups may facilitate participation in community science. Overall, this thesis provides vital recommendations for state agencies aiming to increase BIPOC participation in programs and better engage their constituencies. Through guidance on developing sustainable engagement strategies and how to best support diverse communities, particularly BIPOC groups, this thesis provides insights and recommendations for fostering equitable conservation in an era of environmental change and social evolution.

Building a Comprehensive Understanding of Disturbance Mitigation in Migrating Shorebirds

Mengak, Lara Frances 17 January 2019 (has links)
Human disturbance is a serious threat facing shorebirds, and reducing disturbance presents a significant conservation challenge. It requires an understanding of the complex factors that influence both shorebird biology and human behavior related to shorebirds and coastal environments. This thesis used information from ecological and social science fields, along with the applied knowledge of conservation practitioners to build a more holistic understanding of human-shorebird interactions, specifically related to human disturbance of migrating shorebirds. Further, this research provides practical solutions for better managing these interactions. To accomplish this, we used the Delphi technique, an iterative group communication process, to bring scientists and managers together to develop a shared definition of "human disturbance to shorebirds" and a list of priority disturbance categories that affect migratory shorebirds. Next, we collated and synthesized literature on human disturbance during migration and drivers of human behavior related to disturbance or potential management actions. Then, through manager interviews, we examined how shorebird management decisions are made during migration and explored how managers balance the needs of shorebirds and public use of their sites. The disturbance definition and priority disturbance categories, literature synthesis, and manager interviews were used to create a best practices guidance document for reducing human disturbance to migratory shorebirds in the Northeastern U.S. Finally, we conducted a survey of beachgoers to evaluate a shorebird conservation outreach campaign and examined the factors that influence pro-shorebird behavior change. This research demonstrates how integrating social and ecological information and expert opinion can inform conservation and management. / M. S. / Recreational use of beaches and other coastal environments may negatively impact beach wildlife, such as shorebirds. Reducing the impacts of these potential human disturbances presents a significant challenge to shorebird conservation. This thesis used information from ecological and social science fields, along with the applied knowledge of conservation practitioners to build a more complete understanding of human-shorebird interactions, specifically related to migrating shorebirds. Further, this research provides practical solutions for better managing these interactions. To accomplish this, we used the Delphi technique, an iterative social science method, to bring scientists and managers together to develop a shared definition of “human disturbance to shorebirds” and a list of significant human activities that may negatively affect migrating shorebirds. Next, we collected and synthesized information on human disturbance during migration and aspects of human behavior related to disturbance or potential management actions. Then, through interviews with land managers, we examined how shorebird management decisions are made during migration and explored how managers balance the needs of shorebirds and public use of their sites. The disturbance definition, literature synthesis, and manager interviews were then used to create a management guidance document for reducing human disturbance to migrating shorebirds in the Northeastern U.S. Finally, we conducted a survey with beachgoers to evaluate a shorebird outreach campaign and examined the factors that influence people to adopt more pro-shorebird behaviors. This research demonstrates how integrating social and ecological information and guidance from experts can contribute to shorebird conservation.

Developing Behavioral Indices of Population Viability: A Case Study of California Sea Lions in the Gulf of California, Mexico

January 2012 (has links)
abstract: Despite years of effort, the field of conservation biology still struggles to incorporate theories of animal behavior. I introduce in Chapter I the issues surrounding the disconnect between behavioral ecology and conservation biology, and propose the use of behavioral knowledge in population viability analysis. In Chapter II, I develop a framework that uses three strategies for incorporating behavior into demographic models, outline the costs of each strategy through decision analysis, and build on previous work in behavioral ecology and demography. First, relevant behavioral mechanisms should be included in demographic models used for conservation decision-making. Second, I propose rapid behavioral assessment as a useful tool to approximate demographic rates through regression of demographic phenomena on observations of related behaviors. This technique provides behaviorally estimated parameters that may be applied to population viability analysis for use in management. Finally, behavioral indices can be used as warning signs of population decline. The proposed framework combines each strategy through decision analysis to provide quantitative rules that determine when incorporating aspects of conservation behavior may be beneficial to management. Chapter III applies this technique to estimate birthrate in a colony of California sea lions in the Gulf of California, Mexico. This study includes a cost analysis of the behavioral and traditional parameter estimation techniques. I then provide in Chapter IV practical recommendations for applying this framework to management programs along with general guidelines for the development of rapid behavioral assessment. / Dissertation/Thesis / M.S.

Exploring the “Where” and the “Why” of Conservation Easements: The Role of Community-level Factors in the Likelihood of Adoption

Hemby, Tyler Lee 09 December 2016 (has links)
Over the past several decades conservation easements have seen immense growth in their popularity. There are now over 40 million acres of easement land in the United States, up from only 1.4 million in 1998. A significant body of research exists on easements, factors that lead to their adoption, their consequences and effectiveness, and problems that arise from their use, among other topics. Our study contributes to this literature by exploring community and system-level effects on easement adoption, using Virginia as a case study, and applying a novel approach that incorporates spatial analysis and the insights of conservation professionals. The purpose of our research was to explore whether community-level factors affect easement adoption decisions, and what those factors are. Previously established variables were investigated to gauge their relationship to easement occurrence when scaled up to the community level, as well as to test our ability to make predictions about where easements should be most likely to occur. Spatial market segmentation data was also incorporated into this analysis to determine whether it could augment our understanding of community-level factors and predictive ability. Statistical models produced were reasonably predictive. However, we suspect that this was the case for different reasons at our community scale of analysis than at the individual landowner level examined in previous research. We used surveys and interviews with easement professionals to further explore additional variables that might explain adoption patterns. Results indicate the importance of system-level factors including change agents, opinion leaders, and local government and land-use planning. / Master of Science
