Description
Professional environmental scientists are increasingly under pressure to inform and even shape policy. Scientists engage policy effectively when they act within the bounds of objectivity, credibility, and authority, yet significant portions of the scientific community condemn such acts as advocacy. They argue that it is nonobjective, that it risks damaging the credibility of science, and that it is an abuse of authority. This means objectivity, credibility, and authority deserve direct attention before the policy advocacy quagmire can be reasonably understood. I investigate the meaning of objectivity in science and that necessarily brings the roles of values in science into question. This thesis is a sociological study of the roles environmental values play in the decisions of environmental scientists working in the institution of academia. I argue that the gridlocked nature of the environmental policy advocacy debates can be traced to what seems to be a deep tension and perhaps confusion among these scientists. I provide empirical evidence of this tension and confusion through the use of in depth semi-structured interviews among a sampling of academic environmental scientists (AES). I show that there is a struggle for these AES to reconcile their support for environmentalist values and goals with their commitment to scientific objectivity and their concerns about being credible scientists in the academy. Additionally, I supplemented my data collection with environmental sociology and history, plus philosophy and sociology of science literatures. With this, I developed a system for understanding values in science (of which environmental values are a subset) with respect to the limits of my sample and study. This examination of respondent behavior provides support that it is possible for AES to act on their environmental values without compromising their objectivity, credibility, and authority. These scientists were not likely to practice this in conversations with colleagues and policy-makers, but were likely to behave this way with students. The legitimate extension of this behavior is a viable route for continuing to integrate the human and social dimensions of environmental science into its practice, its training, and its relationship with policy.

Description
This thesis aims to address the ethics of keeping the big cats, such as lions, tigers, and leopards, in zoos. It is a practice that has generated some controversy in light of scientific studies reporting stress among wide-ranging animals in captive enclosures, as well as in the context of wider discussions in animal welfare and conservation ethics in zoos. A driving question for this project, therefore, was "What are the arguments for and against keeping large felids in zoos/captivity?" This thesis examines the historical and current ethical approaches to evaluating the ethics of maintaining big cats in zoos. Due to many of the big cat species listed as endangered species on the IUCN redlist, the species-centered approach to zoo ethics is becoming the common viewpoint, and, as a result, zoos are deemed ethical because of their contribution to ex situ conservation practices. Further, the ethical arguments against zoos are minimized when the zoos provide suitable and appropriate enclosures for their large felids. Of course, not all zoos are created equal; the ethics of zoos need to be evaluated on a case-by-case basis, but in general, it is ethical to maintain big cats in zoos.

In 2007, the Center for Biological Diversity (CBD) petitioned the United States Fish and Wildlife Service (USFWS) and the California Department of Fish and Wildlife (CDFW) to list the American pika (Ochotona princeps) as an endangered species. After several petition denials, the petition was evaluated during both 90-day, and 12-month reviews. Ultimately, both petitions were denied and the pika was not given protection under the Endangered Species Act (ESA). During the petitioning years, 2007 through 2013, there were many newspaper publications, press releases, and blog entries supporting the listing of the pika. Information published by these media ranged from misleading, to scientifically inaccurate. The public was swayed by these publications, and showed their support for listing the pika during the public comment period throughout the 12-month status review in California. While the majority of the public comments were in favor of listing the pika, there were a few letters that criticized the CBD for making a poster child out of a "cute" species. During the 12-month status review, the CDFW contacted pika experts and evaluated scientific literature to gain an understanding of the American pika's status. Seven years after the original petition, the CDFW denied listing the pika on the grounds that the species is not expected to become extinct in the next few decades. This case serves as an example where a prominent organization, the CBD, petitions to list a species that does not warrant protection. Their goal of making the pika the face of climate change failed when species was examined.

Description
Attitudes toward animal welfare have been evolving in our society as we have developed from early agricultural roots to an increasingly urban and technologically advanced community. However, despite the growing societal appreciation and care for animals in our homes and backyards, veterinarians are still faced with cases of abuse and neglect. Although it may seem obvious for veterinarians, as animal welfare advocates, to confront this dilemma each time they are faced with it, that is not always the case. In order to assess the responsibilities of veterinarians in regard to neglect and abuse, an extensive literature review and analysis was performed and practicing veterinarians were interviewed to determine their attitudes regarding the responsibility to report suspected cases of animal neglect and abuse. Specifically, these interviews focused on such topics as the educational background of the practitioners, how empathy impacts their perception of animal welfare, their relationship with law enforcement agencies, and related questions. The study demonstrated that the most prominent factor in a veterinarian's understanding of violations of animal welfare stems from their educational background. Therefore, it is recommended that veterinary medicine programs alter their curricula to emphasize animal welfare training and the obligation of veterinarians to report suspected cases of neglect and abuse.

Description
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.

Description
Amphibians have been experiencing a worldwide decline that is in part caused by an infectious disease, chytridiomycosis, specific to frogs and salamanders. Globally many species have declined or gone extinct because of the pathogenic fungus Batrachochytrium dendrobatidis, also known as the amphibian chytrid or Bd. By the time Bd was discovered it was too late to stop the spread and it has now been found on almost every continent. The trade of captive amphibians, used as pets, bait, and educational animals provides an opportunity to spread Bd. Because some amphibians can carry Bd without experiencing symptoms, it is possible for even healthy looking amphibians to spread the amphibian chytrid if they are moved from one location to another. Recently, a new species Batrachochytrium salamandrivorans (Bsal) was found on salamanders. Bsal was identified before it reached the United States, prompting concern regarding its spread and a call for regulation regarding the trade of captive amphibians. There are some regulations in place controlling the trade of amphibians, but they are insufficient to stop the spread of amphibian chytrid in captive populations. A 2016 law prohibits the importation of 201 salamander species. However, there is no central organization to sample or certify if amphibians are free from Bd or Bsal. Although some stores say they test for these pathogens the tests are unregulated and not reported to any central body. If the captive amphibian trade is to go disease free, there would need to be a significant push to coordinate testing efforts. To estimate Bd's prevalence in Arizona captive amphibian populations, I contacted pet stores, bait stores, and sanctuary or educational organizations to ask if I could sample their amphibian collections. My research built on the 2008 work of Angela Picco, who sampled for the amphibian chytrid in Arizona bait shops. I found that amphibian owners were often hesitant and unwilling to participate in this research opportunity. There are multiple reasons for this hesitancy including a fear of increased regulation, the potential for reporting to a government agency (USDA), or the eventual cessation of amphibian trade. The lack of willing participants suggests there may be difficulties in coordinating future sampling efforts for Bd and Bsal.

Description
Bottlenose dolphins, or Tursiops truncates, have captured the attention of humans for centuries leading people to keep them in captivity. However, people's love and an increase in knowledge for these creatures have sparked many ethical debates on whether dolphins should be kept in captivity. In this paper, I discuss the different dimensions of bottlenose dolphin captivity focusing on the physiological, psychological, ecological and ethical concerns raised when comparing captive to wild bottlenose dolphins. In an analysis of the scientific literature, I found that captive bottlenose dolphins experience negative physical and psychological effects, including a shorter life span and a decrease in brain size. They also engage in more risky and harmful behaviors. Preexisting brain structures in bottlenose dolphins indicate enhanced emotional processing possibly leading to a more difficult life in captivity. Furthermore, modeling of bottlenose dolphin social networks have found that removal of dolphins from existing populations have negative repercussions for ecological communities, particularly effecting present and future pods due to their complex social systems called fission fusion societies. Furthermore, removal can have a deleterious effect on the environment due to their role as top predators. Available data suggest that bottlenose dolphins should be classified as non-human persons due to their cognitive abilities such as self-awareness, intentionality, creativity, and symbolic communication. This moral classification demands significant human duties and responsibilities to protect these cetaceans. Due to their similarities to humans, these results suggest that keeping bottlenose dolphins in captivity is ethically questionable and perhaps unjustifiable as captivity violates their basic rights.

Description
The mainstream American environmental movement has a reputation for being ethnically homogenous (i.e., white), especially within the field of conservation. Low minority involvement has been noted and discussed in the conservation literature and within environmental organizations, but these discussions aren't always informed by the explicit social justice concerns critical to understanding the complex intersection of environmental and social issues. Communities of color have expressed concern for environmental and conservation issues, but often frame those issues in a different way than is common in mainstream conservation science, a framing that we can appreciate through a deeper analysis of the values and goals of the environmental justice (EJ) movement. A more thorough inclusion of EJ principles could be an effective method to increase ethnic diversity in the field of conservation, particularly within higher education conservation programs like the Conservation Biology and Ecology (CBE) concentration at Arizona State University. This thesis frames the broader challenge of diversity in conservation, the history and current state of the conservation movement, and the history of the environmental justice movement via a literature review. I then evaluate the university's CBE program on the basis of its diversity through an analysis of demographic data on undergraduate ethnicity from the School of Life Sciences. I conclude with a series of recommendations for enhancing the diversity of ASU's CBE program moving forward.

Description
Understanding the dynamic interactions between humans and wildlife is essential to establishing sustainable wildlife-based ecotourism (WBE). Animal behavior exists within a complex feedback loop that affects overall ecosystem function, tourist satisfaction, and socioeconomics of local communities. However, the specific value that animal behavior plays in provisioning ecosystem services has not been thoroughly evaluated. People enjoy activities that facilitate intimate contact with animals, and there are many perceived benefits associated with these experiences, such as encouraging pro-environmental attitudes that can lead to greater motivation for conservation. There is extensive research on the effects that unregulated tourism activity can have on wildlife behavior, which include implications for population health and survival. Prior to COVID-19, WBE was developing rapidly on a global scale, and the pause in activity caused by the pandemic gave natural systems the chance to recover from environmental damage from over-tourism and provided insights into how tourism could be less impactful in the future. Until now it has been undetermined how changes in animal behavior can alter the relationships and socioeconomics of this multidimensional system. This dissertation provides a thorough exploration of the behavioral, ecological, and economic parameters required to model biosocial interactions and feedbacks within the whale watching system in Las Perlas Archipelago, Panama. Through observational data collected in the field, this project assessed how unmanaged whale watching activity is affecting the behavior of Humpback whales in the area as well as the socioeconomic and conservation contributions of the industry. Additionally, it is necessary to consider what a sustainable form of wildlife tourism might be, and whether the incorporation of technology will help enhance visitor experience while reducing negative impacts on wildlife. To better ascertain whether this concept of this integration would be favorably viewed, a sample of individuals was surveyed about their experiences about using technology to enhance their interactions with nature. This research highlights the need for more deliberate identification and incorporation of the perceptions of all stakeholders (wildlife included) to develop a less-impactful WBE industry that provides people with opportunities to establish meaningful relationships with nature that motivate them to help meet the conservation challenges of today.

Description
Plastic pollution poses a threat to the health and well-being of marine mammals across the globe. This paper takes a previously developed trait-based risk assessment framework and applies it to all 118 species of marine mammals worldwide, to help create a relative ranking of vulnerability of species to plastic ingestion and entanglement. After extensive data collection on 13 traits related to each species’ relative likelihood of exposure to plastics, species sensitivity to plastic ingestion and entanglement, and overall population resiliency, the initial trait framework was adapted and scored to calculate the relative vulnerability of marine mammals to marine microplastic pollution. Results indicate that the Hawaiian Monk Seal has one of the highest relative vulnerabilities to macroplastic pollution among all marine mammals. Furthermore, this exercise highlighted several areas where future research is needed, including expanding the framework to microplastics, applying the framework to coastal human populations, and further investigation of unknown life history traits of various marine mammals.
