Box turtle (Terrapene carolina) populations have been declining over the last several decades, and one major cause is increasing urbanization. As a result of habitat fragmentation, wildlife managers are frequently turning to new and alternative management strategies. Traditional box turtle management has included relocation, which has been met with limited success. This study aims to combine these strategies with another less-studied one: forcing turtles to overwinter on site by penning them in an outdoor enclosure. Two sets of juvenile box turtles were released at the Virginia Commonwealth University Rice Center: one penned on site in a pen for one year, the other allowed to move freely. Our objective was to compare a variety of factors between these two groups to see if penning was as effective as traditional approaches. Movement and location patterns were tracked using radio transmitters for two years and analyzed using GPS technology. Body condition and health status of all turtles were measured and compared over time as well. Finally, a life history model was developed to determine the effectiveness of management programs. While the penning treatment significantly reduced activity areas, it appears that all juvenile turtles had high site fidelity (87.5%) regardless of treatment. The eastern box turtle seems to be a prime candidate for penning used in conjunction with other management options.

Invasive species are one of the major threats to biodiversity and understanding the effects any one invasive species has on members of its new ecosystem can help land managers decide how to best use their limited resources. This study attempted to show the effect Cuban Treefrogs (Osteopilus Septentrionalis) were having on native Florida hylids. For a year, Cuban Treefrogs were removed from three cypress domes and monitored in three other cypress domes, a change in the native population in the experimental domes was the eventual desired effect. Due to weather issues and low native hylid numbers no effect was shown, however due to environmental constraints an effect could not be ruled out either. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2015. / FAU Electronic Theses and Dissertations Collection

Commercial longline fishing results in large amounts of incidental bycatch of elasmobranch fishes (sharks, skates, and rays). Teleost species lack electrosensory systems and development of technologies which target the ampullary organs of sharks provides an avenue to selectively deter elasmobranchs without affecting the catch rate of target teleosts. Electric field measurements and a controlled scientific longline study were conducted testing whether the lanthanide metal neodymium or zinc/graphite might reduce elasmobranch catch per unit effort (CPUE). Baited longline hooks were treated with neodymium and zinc/graphite and catch rates were compared to that of controls. Shark CPUE decreased by 60% on neodymium treated hooks and 80% on zinc/graphite treated hooks. The effectiveness of both treatments varied among species with significant reductions shown for Atlantic sharpnose sharks (Rhizoprionodon terranovae) but less dramatic differences for others. Zinc/graphite is potentially a viable tool for reduction of shark bycatch in a commercial longline fishery. / by Kieran Thomas Smith. / Thesis (M.S.)--Florida Atlantic University, 2013. / Includes bibliography. / Mode of access: World Wide Web. / System requirements: Adobe Reader.

<p>Tanzania has exceptional wildlife, environment and natural resources. The traditional way of conserving nature and wildlife has been through parks and reserves. In the 1980’s community based conservation emerged as a resource management paradigm. Its premise was that giving local people a stake in wildlife would increase their incentive to conserve it. This would make wildlife an important engine of local economic development. The core elements in community based conservation projects concern development, conservation and sustainable land use. Its ambition both to improve conditions for the local communities and conserve wildlife seems like a win-win situation, but has this really been working that well when applied in the field? This study aims to review the Community Based Wildlife Management in Tanzania, exemplified by a case study in the Wildlife Management Area in Burunge, located in a migration corridor between two national parks. There has been much controversy surrounding community-based management projects. While gains for the local communities have not always been clear, gains for wildlife seem more evident. Both species numbers and individuals have increased, but at the same time there has also been increasing conflicts between locals and wildlife. This is a sign that the WMAs are only halfway to towards reaching their goal of improving conditions for both communities and wildlife. CBC stills seems like the way forwards, maybe in a modified form which allows more government control, but where local people’s rights are still respected.</p>

American elk, by virtue of their distribution, were the most cosmopolitan members of the cervid family at the time of white settlement of North America. At this early date elk were present in every major region of what is now continental United States, as well as in northern Mexico. They likewise were abundant in upper and lower Canada, though records do not corroborate their presence too far north on the Atlantic coast. Although generally existent throughout the western states, elk were sparsely distributed in Nevada, southern Utah, and most of Arizona and New Mexico. Paucity of elk was also noted in eastern portions of Washington and Oregon.
