Natural History and Distribution of the Upland Chorus Frog, Pseudacris feriarum Baird, in West Virginia Thesis submitted to the Graduate College Marshall University In partial fulfillment of the requirements for the degree of Master of Science in Biological Sciences by Jaime Sias Dr. Thomas K. Pauley, Committee Director Dr. Nicki LoCascio, Committee Member Dr. Jeffrey May, Committee Member May 2006 Keywords: Pseudacris feriarum, Natural History, Phenology, Amphibian Declines Copyright © 2006 i Abstract Natural History of the Upland Chorus Frog, Pseudacris feriarum Baird, in West Virginia by Jaime Sias Chapter 1 is a literature review of Pseudacris feriarum, largely based on published P. triseriata Complex species accounts. Chapter 2 presents the natural history of P. feriarum in West Virginia and compares some parameters with other Pseudacris species. Chapter 3 looks at the phenology of a wetland in eastern West Virginia. Chapter 4 examines the current range of P. feriarum and compares it with the historical range in the state. Finally, hypotheses are given as to why Upland Chorus Frogs have declined in West Virginia. All information obtained from this study should be used to create a management plan for the conservation of all present and future P. feriarum populations. ii Acknowledgments I first want to thank Dr. Pauley for taking me under his “wing.” When I joined his lab, the only herps I could identify were newts and box turtles. I quickly learned that he was always available and that I could go to him for anything. He always offered guidance, suggestions and opinions all the while with a smile on his face. Through all his teasing and support, I learned how graduate school could actually be fun. Secondly, I would like to recognize my parents. From an early age, I was told I could do and be anything. I learned one of the most important things in life is to do what you love and you will never have to work a day in your life. I want to express thanks to Ms. Iva Lou Dawson for allowing me unfettered use of her property. Without her assistance, my research would not have gone as smoothly. I also want to thank those who responded to my WVDNR article and the WVDNR who funded this project; without this financial assistance, my research would not have been as easy. Of course I am grateful for my lab mates who I learned from and had fun with while in the field and classroom. To Teresa, who I constantly harassed for computer help; to Zac, who I constantly harassed in general; to Deborah and Kelley who helped in the field; to Ashley who kept me entertained and finally to Geneleen for his superior GIS assistance! I appreciate all who proofread my “book” and offered helpful suggestions. Thanks to Dr. Evans for help in identifying vegetation found at my study site. And finally, thanks to my committee members (Drs. May and LoCascio) who agreed to be part of this experience. iii Table of Contents Abstract....... ........................................................................................................ ii Acknowledgments ............................................................................................. iii Table of Contents............................................................................................... iv List of Figures .................................................................................................... vi List of Tables..................................................................................................... vii Study Site Description......................................................................................viii Chapter 1: Literature Review............................................................................1 Pseudacris Phylogenetic Relationships.............................................................1 Pseudacris feriarum Distribution and Habitats ..................................................2 West Virginia Pseudacris species .....................................................................3 Pseudacris feriarum Phenotypic Characteristics ...............................................4 Pre-breeding (Hibernation)................................................................................5 Breeding............................................................................................................6 Amplexus and Egg Deposition ..........................................................................7 Tadpoles ...........................................................................................................8 Post-breeding (Adults).....................................................................................11 Chapter 2.

INTRODUCTION Rana clamitans , the green frog, is one of the most abundant and widespread ranids in North America. It occurs throughout eastern North America from central Florida to 50° N Latitude in Canada. The literature concerning the species, described in 1801, is vast. With the help of numerous persons, we have attempted to compile a complete bibliography, through 1981, of publications concerning the green frog. We have listed papers and notes containing substantive information about the species, including range records. Papers that only mentioned other references already included are omitted. Although all references have not been checked, we included them if the source were reliable.

ACKNOWLEDGMENT OF SUPPORT This research (contract number 1-5-90179) was funded by the Illinois Department of Transportation. ii EXECUTIVE SUMMARY A study of the biology of the Illinois chorus frog, Pseudacris streckeri illinoensis, is reported. Surveys of Madison County for choruses of the frogs located seven choruses. Choruses previously reported at Granite City and South Roxana were not relocated and are thought to be extirpated. We estimated population size to be 420 frogs in April 1994 with a juvenile survivorship of 4.5%. Mean distance for 20 recaptured frogs from point of initial capture was 0.52 km with a range of 0 to 0.9 km. Habitat preference for 48 frogs found on roads appeared to be for old field habitats in preference to areas of agriculture or lawns.

  • Mercury in Northern Green Frogs and Snapping Turtles from Onondaga Lake, New York
    MERCURY IN NORTHERN GREEN FROGS AND SNAPPING TURTLES FROM ONONDAGA LAKE, NEW YORK Prepared by the New York Field Office of the U. S. Fish and Wildlife Service December 2015 For the Onondaga Lake Natural Resource Damage Assessment and Restoration Trustee Council i ABSTRACT This study was conducted to develop an initial understanding of the exposure of amphibians and reptiles at Onondaga Lake to mercury (Hg). Mercury in Onondaga Lake northern green frogs is within the range of Hg concentrations shown to affect metamorphosis and survival of southern leopard frog tadpoles and metamorphs, but less than concentrations associated with effects in wood frogs and American toads. Mercury in the toenails and blood of snapping turtles from Onondaga Lake was significantly higher than Hg in the toenails and blood of Hamlin Wildlife Management Area (reference area) snapping turtles. Onondaga Lake snapping turtles have more Hg in their keratinous tissue (toenails) than other snapping turtles sampled across New York State, but less Hg than found in keratinous tissues of snapping turtles from a Hg-contaminated area in Virginia. Snapping turtles appear fairly resistant to Hg, but the Hg concentrations found in Onondaga Lake snapping turtles are within the range of concentrations associated with altered thyroid function and immune suppression in other turtle species. Although the diversity of amphibians and reptiles has increased at Onondaga Lake over the past two decades, the herpetofaunal diversity and population densities remain lower than in surrounding areas. This study shows that Hg may be a factor inhibiting the reproduction and health of some amphibians and reptiles at Onondaga Lake.
