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
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
The Committee on Rare and Endangered Wildlife Species (CREWS) of the U.S. Fish and Wildlife Service (FWS) made important and lasting contributions to one of the most significant pieces of environmental legislation in U.S. history: the Endangered Species Act of 1973 (ESA). CREWS was a prominent science-advisory body within the U.S. Department of the Interior (DOI) in the 1960s and 1970s, responsible for advising on the development of federal endangered-wildlife policy. The Committee took full advantage of its scientific and political authority by identifying a particular object of conservation--used in the development of the first U.S. list of endangered species--and establishing captive breeding as a primary conservation practice, both of which were written into the ESA and are employed in endangered-species listing and recovery to this day. Despite these important contributions to federal endangered-species practice and policy, CREWS has received little attention from historians of science or policy scholars. This dissertation is an empirical history of CREWS that draws on primary sources from the Smithsonian Institution (SI) Archives and a detailed analysis of the U.S. congressional record. The SI sources (including the records of the Bird and Mammal Laboratory, an FWS staffed research group stationed at the Smithsonian Institution) reveal the technical and political details of CREWS's advisory work. The congressional record provides evidence showing significant contributions of CREWS and its advisors and supervisors to the legislative process that resulted in the inclusion of key CREWS-inspired concepts and practices in the ESA. The foundational concepts and practices of the CREWS's research program drew from a number of areas currently of interest to several sub-disciplines that investigate the complex relationship between science and society. Among them are migratory bird conservation, systematics inspired by the Evolutionary Synthesis, species-focused ecology, captive breeding, reintroduction, and species transplantation. The following pages describe the role played by CREWS in drawing these various threads together and codifying them as endangered-species policy in the ESA.
