Endangered species

The Gull-billed Tern is a globally distributed species. Distribution in the United States is limited, however, with the majority of breeding birds being found in Texas. The remainder can be found scattered throughout the southeastern states. Florida has a mere 1.6% of the breeding birds in the U.S. This study has accumulated all breeding records of the Gull-billed Tern in Florida since 1973, and distribution trends were analyzed. Since 1973 the population of these birds has fluctuated widely and experienced an alarming decline of about "95% between 1975 and 1999" (Smith, in press.). I determined that the current status of this bird in Florida mandates that further conservation efforts occur rapidly in order to protect its diminishing population. This study examines those conservation measures already in place, and those pending, such as my petition to list this species as "threatened" under the endangered species provisions of the Florida Wildlife Code (Chap. 39 F.A.C.).

Throughout the course of North American history, wolves have been persecuted with a vengeance. Negative wolf perceptions have in the past created and continue to create controversial policies and views towards wolves. While most of these attitudes are geared towards gray wolves, as gray wolves are the most common and prominent, unfavorable perceptions have also extended to the less well-known red wolf. This study compares two red wolf reintroduction programs, one in the Tennessee-Kentucky area and the other in North Carolina, as well as the Yellowstone Gray Wolf Reintroduction program. After analyzing these three programs, it can be concluded that the perceptions towards wolves regardless of the type of wolf or location remain largely negative and that wolves continue to face persecution.

This study assesses the philosophical underpinnings of endangered species protections focused on gopher tortoises in Florida. From 1993-2007, gopher tortoises (Gopherus polyphemus) were listed in Florida as a species of special concern. Land developers wanting to build on their habitats could apply for an incidental take permit, paying a fee that allowed tortoises to be 'entombed' in their burrows to die a slow death. In 2007, when gopher tortoise status was up-losted to 'threatened', a new policy ended the incidental take permit program. This study compares policy guidelines of the 1991 and 2007 gopher tortoise management plans and explores cases that deal with incidental take controversies. I will apply perspectives from environmental philosophy to my analysis to understand how policies attempt to balance economic goals with a mandate to protect species in peril.

The cheetah (Acinonyx jubatus) continues to be an object of intensive study with respect to its genetic heterozygosity and its drastic decline in the wild. Fluctuating asymmetry (FA) has been used to evaluate the levels of inbreeding and monomorphism in the cheetah. A measurement of craniodental FA was undertaken to compare the southern African cheetah (Acinonyx jubatus jubatus) with previously collected craniodental FA measurements from the East African cheetah (Acinonyx jubatus raineyi). Unlike their counterparts, the southern African cheetah did not show significant asymmetry. These findings suggest that fluctuating asymmetry cannot be used as a determination of genetic depletion in cheetahs.
