Abstract This thesis is derived from the conservation biology field of study and seeks to chronicle and characterize the history of wolf conservation in the US, with a focus on post-ESA listing and present day events. The compelling question this thesis seeks to address is how to make long-term wolf conservation effective and feasible in the United States. An overview of wolf life history is provided, as well as a brief overview of early wolf-human interactions in Europe and the US, before reviewing the following regions in the US: Yellowstone, Idaho/Montana/Wyoming, Alaska, and Arizona. The trend identified in all regions is described as a hostile political atmosphere with particular resentment by some stakeholders towards the federal enforcement of wolf conservation via the ESA. A comparative section on Italy is provided in contrast to this US theme, as Italy tends to have a much more relaxed attitude towards wolf conservation. For success in the future of wolf conservation three suggestions are made. First, efforts to protect wolves through federal regulation are to be dismissed. Second, efforts should instead focus on education of key demographics regarding responsible environmental management and wolf management specifically. Thirdly, conservationists must actively strive to remarket the wolf as a symbol of the freedom of the west as opposed to the symbol of Washington's encroachment on state's rights.

Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in upholstery, plastics, clothing, and other products to reduce fire danger, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. By summarizing various metrics of sustainability and the mercury content in consumed species of fish and shellfish, researchers have found that high levels of chemical contamination was linked with lesser fishery sustainability. I conducted a literature review of flame retardant content in seafood to further compare contamination and sustainability in addition to the initial analysis with mercury. My review suggests that the widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are mutually disadvantageous for both human consumers and the environment. Future research should address the need for the collection of data that better represent actual global contaminant concentrations in seafood.

Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in textiles, upholstery, plastics, and other products to reduce risk of fire-related injury, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. The widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are also unhealthy and mutually disadvantageous for both human consumers and the environment. To thoroughly investigate the confounding factors and contradictory signals enmeshed in the relationship between ecologically sustainable fisheries and flame retardant contamination, I examined the biological characteristics of regional fish stocks which drive both contamination and perceived sustainability. I found that the biological and spatial aspects of commonly consumed aquatic and marine species best predict contamination when compared with various indices of sustainability. My results confirm that knowledge of flame retardant toxicity will become increasingly more important to consumers because a high percentage of global populations rely on coastal seafood for subsistence, and although dispersal of chemical contamination is still a poorly understood phenomenon, fish harvested closer to land are likely to contain higher concentrations of potentially harmful chemicals. Because some of the same biological traits which facilitate the uptake of chemicals also contribute to how a species responds to fishing pressures, concern for private health increases public consideration for the conservation of species at risk.

In the Alto Mayo Protection Forest (AMPF) of San Martín, Peru, unsustainable farming practices in coffee agroecosystems are the main drivers of deforestation and habitat loss. Previous studies indicate that across Latin American coffee farms, using shade-grown coffee result in higher biodiversity on the farms with a larger abundance of floral and faunal species. In AMPF, conservation agreements have been implemented between cultivators and Conservation International to ameliorate the environmental damages incurred by poor farming practices, as well as to increase cultivator livelihoods. To measure the effectiveness of these agreements, we compared camera trap data to drone-captured shade cover data to find the correlation between higher shade cover and biodiversity among subscriber plots. While our results showed no interrelationship between shade cover and species abundance or richness, this study was a small subset of the larger study, representing only 15% of the total subscriber plots and 24% of the overall sectors. Therefore, we predict that the results of the larger study will be more conclusive and will better indicate the predicted positive relationship between biodiversity and agroecology in AMPF.

The status of Earth’s diversity is deteriorating quickly which will continue to impact humans’ way of life, as well as every other living creature, in all regions of the world. However, there are organizations taking action to protect biodiversity on our planet. The Convention on Biological Diversity (CBD) is one of those organizations and includes 196 signatories from around the world who are committed to strategies to preserve their biodiversity (Secretariat). Indeed, 98% of the parties which have participated in the Convention on Biological Diversity (CBD) have created national biodiversity strategies (NBS) and action plans (NBSAPs) (Secretariat). Yet, there are still countries that have yet to partake in these efforts. America continues to hold out against ratifying the CBD and remains the only developed country without a National Biodiversity Strategy. As an NBS for the U.S. is under consideration, my goal is to understand what works from previous plans. In particular, I focus on stakeholder engagement in Conservation Biodiversity Action Plans. Stakeholder engagement is important because, without it, there may be insufficient levels of integration of the action plans, which can lead to the failure of the CBDs conservation efforts. To address this question, I analyze the 193 strategies created for countries across the globe. My review describes the ways that stakeholders are engaged in National Biodiversity Strategies for CBD member countries. All plans mention some form of engagement. The most common types mentioned are ‘Education’, ‘Communication’, and ‘Training’. Examining the plans further reveals that most forms of engagement often are just mentioned and not completed. Close to 58% of the engagement forms are only completed about 50% of the time. Exceptions are surveys, interviews, and workshops, which are each completed in over 70% of plans that mention them. I then use this information to provide practical recommendations for creating an effective NBSAP for the United States.
