Rodent eradications undertaken on tropical islands are more likely to fail than eradications undertaken at higher latitudes. We report on 12 independent rodent eradication projects undertaken on tropical islands that utilized the results of an in situ bait availability study prior to eradication to inform, a priori, the bait application rate selected for the eradication. These projects also monitored bait availability during the eradication. The results from our analysis verified the utility of bait availability studies to future rodent eradication campaigns and confirmed the influence of two environmental factors that can affect bait availability over time: precipitation prior to the …

The Pleistocene was characterized by worldwide shifts in community compositions. Some of these shifts were a result of changes in fire regimes, which influenced the distribution of species belonging to fire-dependent communities. We studied an endangered juniper–oak shrubland specialist, the black-capped vireo (Vireo atricapilla). This species was locally extirpated in parts of Texas and Oklahoma by the end of the 1980s as a result of habitat change and loss, predation, brood parasitism, and anthropogenic fire suppression. We sequenced multiple nuclear loci and used coalescence methods to obtain a deeper understanding of historical population trends than that typically available …
Resilience Thinking And Structured Decision Making In Social-Ecological Systems, Noelle M. Hart
Resilience Thinking And Structured Decision Making In Social-Ecological Systems, Noelle M. Hart
School of Natural Resources: Dissertations, Theses, and Student Research
Natural resource management may be improved by synthesizing approaches for framing and addressing complex social-ecological issues. This dissertation examines how structured decision making processes, including adaptive management, can incorporate resilience thinking. Structured decision making is a process for establishing a solid understanding of the problem, values, management options, and potential consequences. Adaptive management is a form of structured decision making in which uncertainty is reduced for iterative decisions through designed monitoring and review. Resilience thinking can help conceptualize complex social-ecological systems and draws attention to the risks of managing for narrowly-focused objectives.
This dissertation provides practical advice to managers and …

How Access To Plant & Animal Books Affects Participation In Conservation Activities, Dustin Ingram, Hassnaa Ingram
How Access To Plant & Animal Books Affects Participation In Conservation Activities, Dustin Ingram, Hassnaa Ingram
Library Philosophy and Practice (e-journal)
Abstract
Public libraries are an important resource for communities. Access to plant and animal books impacts a communities’ ability to learn about their environment. In this study, the number of plant and animal books available to people through local libraries in northern Kentucky, and neighboring counties in Ohio and Indiana were counted and a survey assessing one’s preferences and likeliness to participate in conservation activities was distributed to local residents. Based on the collected data, a statistically significant relationship (p < 0.05) was found between access to plant and animal books available at local libraries and the likelihood of people to participate in conservation activities. Further analysis was performed between the total number of shelved plant and animal books at local libraries, the total number of shelved juvenile plant and animal books and the shelved adult plant and animal books, and the total number of plant and animal books in libraries compared to the local household income and number of households near a library. This study found that people that read books about plants and animals were more likely to participate in conservation activities associated with their book preference. This study also found that people living in low-income communities with fewer households are less likely to participate in plant and animal conservation, as compared to higher-income communities with a higher number of households. Additionally, this study found that lower income areas have fewer plant and animal books on the library shelves than higher income areas. Consequently, study results suggest that if more plant and animal books were made available to low-income areas and areas of biological importance through libraries, people may be more likely to conserve the wildlife around them.
Land And Law In The Age Of Enterprise: A Legal History Of Railroad Land Grants In The Pacific Northwest, 1864-1916, Sean M. Kammer
Land And Law In The Age Of Enterprise: A Legal History Of Railroad Land Grants In The Pacific Northwest, 1864-1916, Sean M. Kammer
Department of History: Dissertations, Theses, and Student Research
Federal land subsidies to railroad corporations comprised an important part of the federal government’s policies towards its western land domain in the middle decades of the nineteenth century. In all, Congress granted over a hundred million acres to railroad corporations to subsidize construction of a transcontinental railway network. Long after the last such grant in 1871, these land grants continued to incite political contests in Congress and state legislatures and legal disputes in communities across the West. By the end of the century, railroad corporations had become manifestations not just of the threatening growth of corporate power in the United …

Diversion (i.e. extraction) of water from rivers and estuaries can potentially affect native wildlife populations if operation is not carefully managed. For example, open, unmodified water diversions can act as a source of injury or mortality to resident or migratory fishes from entrainment and impingement, and can cause habitat degradation and fragmentation. Fish-protection devices, such as exclusion screens, louvres or sensory deterrents, can physically or behaviourally deter fish from approaching or being entrained into water diversions. However, empirical assessment of their efficacy is often lacking or is investigated only for particular economically or culturally important fishes, such as salmonids. The …

Effective communication of science to the general public is important for numerous reasons, including support for policy, funding, informed public decision making, among others. Prior research has found that scientists participating in public policy and public communication must frame their communication efforts in order to connect with audiences. A frame is the mechanism that individuals use to understand and interpret the world around them. Framing can encourage specific interpretations and reference points for a particular issue or event; especially when meaning is negotiated between the media and public audiences. In this study, we looked at the effect of framing within …

Protected areas (PAs) remain central to the conservation of biodiversity. Classical PAs were conceived as areas that would be set aside to maintain a natural state with minimal human influence. However, global environmental change and growing cross-scale anthropogenic influences mean that PAs can no longer be thought of as ecological islands that function independently of the broader social-ecological system in which they are located. For PAs to be resilient (and to contribute to broader social-ecological resilience), they must be able to adapt to changing social and ecological conditions over time in a way that supports the long-term persistence of populations, …

Hybridization presents a unique challenge for conservation biologists and managers. While hybridization is an important evolutionary process, hybridization is also a threat formany native species. The endangered species recovery effort for the red wolf Canis rufus is a classic system for understanding and addressing the challenges of hybridization. From 1987‒1993, 63 red wolves were released from captivity in eastern North Carolina, USA, to establish a free-ranging, non-essential experimental population. By 1999, managers recognized hybridization with invasive coyotes Canis latrans was the single greatest threat to successful recovery, and an adaptive management plan was adopted with innovative approaches for managing the …
