This project studied the effects of wetland restoration on amphibian populations. These wetlands were Carolina bays located on the Savannah River Site, located near Aiken, S.C. The Savannah River Site is a National Environmental Research Park owned and operated by the U.S. Department of Energy. The study sites included three reference bays (functionally intact), three control bays (with active drainage ditches), six treatment bays (restored during 2001), and four bays near two of the treatment bays (in effect creating two metapopulations).

520 $a This project studied the effects of wetland restoration on amphibian populations. These wetlands were Carolina bays located on the Savannah River Site, located near Aiken, S.C. The Savannah River Site is a National Environmental Research Park owned and operated by the U.S. Department of Energy. The study sites included three reference bays (functionally intact), three control bays (with active drainage ditches), six treatment bays (restored during 2001), and four bays near two of the treatment bays (in effect creating two metapopulations).
520 $a Amphibians at each bay were captured, marked, and released between January and July, 2000--2003. 2000 was a pre-restoration year, the bays were restored prior to the trapping season in 2001, and 2002 and 2003 being post-restoration years. Each bay was partially encircled with drift fences and pitfall traps. Amphibians were given batch marks that designated the year and bay of capture.
520 $a A total of 43,432 amphibians of 24 species were captured during the study. While I documented a decrease in salamander populations during this study, the restoration appears to have provided additional breeding habitat for several anuran species.
520 $a In addition, I present survival estimates for 2 salamander species, Amhystoma maculatum, and A. talpoideum. These estimates were lower than previously reported for these species, however two years of this study were conducted during drought conditions which may have impacted these results.
520 $a In addition, we present information on environmental variables and responses of A. opacum, and A. talpoideum, as well as 2 species of anurans, Bufo terrestris, and Scaphiopus holbrooki.
520 $a Ambystoma species are believed to be highly philopatric, returning to the natal pond to breed. I examined the genetic structure of two species, A. talpoideum (mole salamanders) and A. opacum (marbled salamanders) in 16 Carolina bays. Amplified fragment length polymorphisms (AFLP) were used to determine genetic variation within and among populations of salamanders separated by distances of 150 m to 25 km. Although this technique was capable of verifying variation between the species, we were unable to document genetic structure at the population level for either of these species.
