research certainly could not have been completed without the support and guidance of many individuals. In particular, I want to thank my advisor. Dr. Romuald Lipcius, whose suggestion it was that 1 attend the diamondback terrapin symposium in 2007 that led me to tackling this project. I am also grateful to Dr. Randy Chambers for answering my questions while I learned about all things terrapin. I want to acknowledge the depth and expertise of my remaining committee, Drs. Rochelle Seitz, Willem Roosenburg, Eric Hilton, and Drew LaMar for reminding me of the reality of competitive research, and encouraging me to keep moving forward. I would also express my deep appreciation to the entire faculty in the School of Marine Science for their dedication and willingness to impart their experiences and knowledge with all of us graduates students.

Diamondback terrapins are the only turtles that live in brackish (a mix of salt and fresh) water. Terrapin Fast Facts! • Females are usually bigger than males. Do you know why? •Females are larger because they are responsible for carrying the eggs. •They also have smaller tails that don’t get in the way when laying the eggs. • Females leave the water to nest above the high tide line. • They lay about 8-12 eggs. • Females will dig a nest with their back leg. • This plaster mold shows the size and shape of a nest. Egg chamber WHY IS THE FEMALE TERRAPIN MORE ENDANGERED? • Most turtles that cross the road are females. • Females enter the roadway because they are looking for suitable nesting sites. Because males do not have to do this, they are usually not the ones to get hit by cars.

  • Movement and Habitat Use of Two Aquatic Turtles (Graptemys Geographica and Trachemys Scripta) in an Urban Landscape
    Urban Ecosyst DOI 10.1007/s11252-008-0049-8 Movement and habitat use of two aquatic turtles (Graptemys geographica and Trachemys scripta) in an urban landscape Travis J. Ryan & Christopher A. Conner & Brooke A. Douthitt & Sean C. Sterrett & Carmen M. Salsbury # Springer Science + Business Media, LLC 2008 Abstract Our study focuses on the spatial ecology and seasonal habitat use of two aquatic turtles in order to understand the manner in which upland habitat use by humans shapes the aquatic activity, movement, and habitat selection of these species in an urban setting. We used radiotelemetry to follow 15 female Graptemys geographica (common map turtle) and each of ten male and female Trachemys scripta (red-eared slider) living in a man-made canal within a highly urbanized region of Indianapolis, IN, USA. During the active season (between May and September) of 2002, we located 33 of the 35 individuals a total of 934 times and determined the total range of activity, mean movement, and daily movement for each individuals. We also analyzed turtle locations relative to the upland habitat types (commercial, residential, river, road, woodlot, and open) surrounding the canal and determined that the turtles spent a disproportionate amount of time in woodland and commercial habitats and avoided the road-associated portions of the canal. We also located 21 of the turtles during hibernation (February 2003), and determined that an even greater proportion of individuals hibernated in woodland-bordered portions of the canal. Our results clearly indicate that turtle habitat selection is influenced by human activities; sound conservation and management of turtle populations in urban habitats will require the incorporation of spatial ecology and habitat use data.

  • Diamondback Terrapin Malaclemys Terrapin Contributors: Dubose Griffin, David Owens and J
    Diamondback Terrapin Malaclemys terrapin Contributors: DuBose Griffin, David Owens and J. Whitfield Gibbons DESCRIPTION Taxonomy and Basic Description The diamondback terrapin is a small, long-lived estuarine turtle endemic to coastal marshes, estuarine bays, lagoons and creeks ranging from Cape Cod, Massachusetts to the Gulf Coast of Texas. Currently, there are five (Hartsell 2001) or seven (Ernst et al. 1994) subspecies. More recently, Hart (2004) identified six management units. The subspecies found in South Carolina is Malaclemys terrapin centrata. Terrapins have varied coloration from black to spotted patterns on the soft tissue and dark or light-colored scutes with strong concentric layers on the carapace. The hind margin of the carapace curls up instead of flaring. Hind legs are large and toes have extensive webs. These turtles are strong, fast swimmers that feed on a variety of mollusks, crustaceans and other invertebrates. In South Carolina, salt marsh periwinkles (Littoraria irrorata) and blue crabs (Callinectes sapidus) are among the terrapin’s primary food sources (Tucker et al. 1995; Levesque 2000). Terrapins are sexually dimorphic. Females are much larger than males and reach 15 to 18 cm (6 to7 inches) in length; males reach 10 to 13 cm (4 to 5 inches) in length. Adult females also have enlarged heads. Terrapins hibernate in the mud during winter and mate in the spring. Eggs are laid May through early August and clutches have 5 to 12 eggs (Pritchard 1979). The number of clutches laid per female in South Carolina is undocumented; however two clutches may be common (David Owens, College of Charleston, pers.

  • Three New Subspecies of Trachemys Venusta (Testudines: Emydidae) from Honduras, Northern Yucatán (Mexico), and Pacific Coastal Panama
    Three New Subspecies of Trachemys venusta (Testudines: Emydidae) from Honduras, Northern Yucatán (Mexico), and Pacific Coastal Panama By William P. McCord1, Mehdi Joseph-Ouni2, Cris Hagen3, and Torsten Blanck4 1East Fishkill Animal Hospital, Hopewell Junction, NY, USA; 2EO Wildlife & Wilderness Conservation, Brooklyn NY, USA; 3Savannah River Ecology Laboratory, Aiken, SC, USA; 4Forstgartenstr 44, Deutschlandsberg, Austria Abstract. Upon examination of live and preserved specimens from across the species range, several unnamed distinct forms of Trachemys venusta (Gray, 1855) were recognized, leading to the description here of three biogeographically isolated, morphologically distinct subspecies: Trachemys venusta uhrigi ssp. nov., Trachemys venusta iversoni ssp. nov., and Trachemys venusta panamensis ssp. nov. Head and neck stripes, along with cara- pacial and plastral patterns are critical to identification in this group. Formal descriptions and diagnoses are given herein. Other Central American Trachemys are also discussed for comparison. Keywords: Turtle, emydid, Trachemys venusta uhrigi ssp. nov., Trachemys venusta iversoni ssp. nov., Trachemys venusta panamensis ssp. nov., Honduras, Mexico, Panama, Meso-America. Slider turtles of the genus Trachemys GRAY (1855) declared eight syntypes for his “Venus- Agassiz, 1857, range from north and east of like” Emys without designating a holotype. However, the Rio Grande in the United States, in 1873 he referred to only one syntype as “Emys through Mexico, Central America, the venusta”: stuffed specimen “e” (1845.8.5.26) in the West Indies, and South America as far as British Museum of Natural History, labeled “Charming northeastern Argentina. IVERSON (1985) resurrect- Emys” for its beautiful pattern — this reference led ed Trachemys from synonymy with Pseudemys (Gray, SMITH and SMITH (1979) to designate BMNH 1855).
