Movement and Habitat Ecology of Protected Species in North Carolina MOVEMENT AND HABITAT ECOLOGY OF PROTECTED SPECIES IN NORTH CAROLINA A thesis presented to the faculty of the Graduate School of Western Carolina University in partial fulfillment of the requirements for the degree of Master of Science in Biology. By Samuel T.S. McCoy Director: Dr. Joseph H.K. Pechmann Associate Professor of Biology Biology Department Committee Members: Dr. Jeremy Hyman, Biology Lori Williams, North Carolina Wildlife Resources Commission October 2016 ACKNOWLEDGEMENTS This thesis is dedicated in memory of my father, William McCoy, who encouraged me to take my first field biology course as an undergraduate student, which made me fall in love with field ecology work. Likewise, I would like to thank Dr. Kristin Stanford, an early mentor who helped me discover my love of herps. Without their initial nudging and guidance, I would not have gone down this path, and this thesis would cease to exist. I would like to thank my advisor, Dr. Joe Pechmann, for the countless hours you spent discussing ideas with me, the many emails answered in the wee hours of the night, and for pushing me to attend meetings, present my research, and network. Thanks to your efforts I am confident I can succeed in this profession. I would like to thank my committee, including Dr. Jeremy Hyman and Lori Williams, for all of your guidance planning, conducting, and finishing this research. Thank you to Dr. Tom Martin for help with statistical analysis. Thank you to Dr. Beverly Collins for help with the plant aspects of my research. Thank you to Dr. J.P. Gannon and Dr. Dave Kinner for help with the soil aspects of my research. Thank you to Dr. Ron Davis and Dr. Bill Sutton for help with home range calculations. Thank you to Gabrielle Graeter with the North Carolina Wildlife Resources Commission for assisting with my bog turtle work. I would like to thank the North Carolina Wildlife Resources Commission, Highlands Biological Station, and the Western Carolina University Graduate School for providing me funding for equipment, gas, and my time. I would like to thank Robin Taylor with the USDA Forest Service Beech Creek Seed Orchard for allowing me to work on their land. ii Last but certainly not least, I need to thank all of the amazing people who helped me chase frogs and turtle for months, especially those who braved the bog. Not only did you help me accomplish my field work, but you helped me keep my sanity while doing so. Thank you to Courtney Anderson, Emily Ashe, Sean Binninger, Cameron Duke, Jessica Duke, Thom Green, Michael Frazier, Alyssa Fuller, Joey Kennedy, Ashley LaVere, Charles Lawson, Nicel Macias, Rob McKinnon, Collin McRae, Naaman McRae, Ashley Murray, Kendra Person, Kyle Pursel, Sarah Pursel, Eli White, and the WCU undergraduate and graduate Methods in Ecology classes. iii TABLE OF CONTENTS List

  • Baseline Population Inventory of Amphibians on the Mountain Longleaf National Wildlife Refuge and Screening for the Amphibian Disease Batrachochytrium Dendrobatidis
    Baseline Population Inventory of Amphibians on the Mountain Longleaf National Wildlife Refuge and Screening for the Amphibian Disease Batrachochytrium dendrobatidis This study was funded by the U.S. Fish & Wildlife Service Southeast Region Inventory and Monitoring Network FY 2012 September 2013 Gregory Scull1 Chester Figiel1 Mark Meade2 Richard Watkins2 1U.S. Fish and Wildlife Service 2Jacksonville State University, Jacksonville, Alabama The findings and conclusions in this article are those of the author(s) and do not necessarily represent the views of the U.S. Fish and Wildlife Service. Introduction: Amphibians are facing worldwide population declines, range contractions, and species extinction. Within the last 30 years, over 200 species have become extinct and close to one-third of the world’s amphibians are imperiled (IUCN, 2010). A recent trend analysis indicates that amphibian decline may be even more widespread and severe than previously realized and includes species for which there has been little conservation concern or assessment focus in the past (Adams et al. 2013). Factors such as invasive species, disease, changes in land use, climate change effects and the interactions of these factors all form current hypotheses that attempt to explain this dilemma (McCallum, 2007). This is alarming considering that the Southeast contains the highest level of amphibian diversity in the United States. It is imperative that we obtain and maintain current information on amphibian communities inhabiting our public lands so that we can adaptively manage resources for their long-term survival. Although a number of causes appear related to amphibian declines in recent years, one of the leading factors is the infectious disease known as chytridiomycosis.

  • Identifying Priority Ecoregions for Amphibian Conservation in the U.S. and Canada
    Acknowledgements This assessment was conducted as part of a priority setting effort for Operation Frog Pond, a project of Tree Walkers International. Operation Frog Pond is designed to encourage private individuals and community groups to become involved in amphibian conservation around their homes and communities. Funding for this assessment was provided by The Lawrence Foundation, Northwest Frog Fest, and members of Tree Walkers International. This assessment would not be possible without data provided by The Global Amphibian Assessment, NatureServe, and the International Conservation Union. We are indebted to their foresight in compiling basic scientific information about species’ distributions, ecology, and conservation status; and making these data available to the public, so that we can provide informed stewardship for our natural resources. I would also like to extend a special thank you to Aaron Bloch for compiling conservation status data for amphibians in the United States and to Joe Milmoe and the U.S. Fish and Wildlife Service, Partners for Fish and Wildlife Program for supporting Operation Frog Pond.

  • Frogs of Anderson County, TN When It Comes to Loveable Animals, Frogs Receive High Marks from Kids and Adults Alike
    Frogs of Anderson County, TN When it comes to loveable animals, frogs receive high marks from kids and adults alike . There are 14 different kinds of frogs in our area, with some species being much more common than others. A few species are rarely found in Anderson County while others - like the Spring Peeper below - can be heard calling throughout the county. We have not heard one species - the Northern Cricket Frog - in Anderson County since the early 1980s. Learning frog calls is an excellent way to improve your listening skills and is important for helping conserve our local frog populations and other biodiversity. Be sure to check out the Resources Page on the back which lists websites that showcase the calls of Tennessee frogs. Spring Peeper Habitat availability and condition are the two most important factors for determining where frog populations are found — froggy cannot go a-courtin’ without the proper environment! This guide will help you identify our local species and also provide resources for improving or creating good frog habitat. Frogs in our area are classified into one of five families based on their characteristics. For example, 5 of our 14 species belong to the treefrog family which is typically characterized by expanded toe tips for climbing and the ability to vary their coloration. The frogs in this guide are organized by family, but keep in mind that frogs are wonderfully diverse and some species may or may not have physical traits or behaviors which precisely conform to their family characteristics. This schoolyard wetland in Norris, TN is a great habitat for both frogs and kids.

  • The Role of Forest Composition on Pool-Breeding Amphibians: Colonization, Larval Communities, and Connectivity
    The Role of Forest Composition on Pool-breeding Amphibians: Colonization, Larval Communities, and Connectivity Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Michael Paul Graziano, M.S. Graduate Program in Environment and Natural Resources The Ohio State University 2017 Dissertation Committee: Stephen N. Matthews, Advisor H. Lisle Gibbs Patrick Charles Goebel Roger A. Williams Copyright by Michael Paul Graziano 2017 ! Abstract Few studies investigate the intricate effects that the plant community has on amphibian populations. Plants shape ecosystems, affecting both physical and chemical attributes of the landscape. Conspicuous artifacts of the plant community include canopy cover, physical structure, and modified temperature and moisture profiles. However, less conspicuous artifacts of the tree community, namely the physiochemical characteristics of their resulting leaf litter, have the ability to shape their ecosystem just as greatly as their more conspicuous traits. Leaf litter represents the primary energy source in vernal pools and other aquatic systems that are critical amphibian breeding habitat. As plant communities shift across the landscape due to ecosystem degradation, invasion by nonnative species, climate change, and shifting disturbance regimes, there is a critical need to investigate how these potential changes can influence the amphibian community and the mechanisms by which they occur. My research investigates
