SEARCY, Department of Biology, University of Miami, 1301 Memorial Drive, Coral Gables, FL 33146, USA ABSTRACT The long‐term viability of gopher tortoise (Gopherus polyphemus) populations is jeopardized by increased urbanization and habitat degradation owing to fire suppression. Because the species’ remaining natural habitats in the southeastern United States exist within a mosaic of anthropogenic land uses, it is important to understand demographic responses to contrasting land uses and habitat management regimes. We examined differences in demographic parameters among fire‐suppressed sandhill, restored sandhill, and former sandhill (i.e., ruderal) land use‐land cover (LULC) types at Archbold Biological Station in south‐ central Florida, USA. Using Program MARK, we estimated population size, and sex‐specific and LULC‐specific survivorship based on 6 years of mark‐recapture data. We also analyzed individual growth trajectories and clutch sizes to determine whether growth rates or reproductive output differed among LULC types. Tortoises in an open, ruderal field occurred at a higher density (7.79/ha) than in adjacent restored (1.43/ha) or fire‐suppressed (0.40/ha) sandhill. Despite this higher density, both adult survivorship and body size were significantly higher in the ruderal field. -

Classification Order: Testudines Family: Chelydridae Genus: Chelydra Species: serpentina (Linnaeus, 1758) Previous research on Chelydra serpentina (Phillips et al., 1996) acknowledged four subspecies, C. s. serpentina (Northern U.S. and Figure 2. Side profile of Chelydra serpentina. Note Canada), C. s. osceola (Southeastern U.S.), C. s. the serrated posterior end of the carapace and the rossignonii (Central America), and C. s. tail’s raised central ridge. Photo from http://pelotes.jea.com/AnimalFact/Reptile/snapturt.ht acutirostris (South America). Recent IUCN m. reclassification of chelonians based on genetic analyses (Rhodin et al., 2010) elevated C. s. rossignonii and C. s. acutirostris to species level and established C. s. osceola as a synonym for C. s. serpentina, thus eliminating subspecies within C. serpentina. Antiquated distinctions between the two formerly recognized North American subspecies were based on negligible morphometric variations between the two populations. Interbreeding in the overlapping range of the two populations was well documented, further discrediting the validity of the subspecies distinction (Feuer, 1971; Aresco and Gunzburger, 2007). Therefore, any emphasis of subspecies differentiation in the ensuing literature should be disregarded. Figure 3.

MICHENER, University Libraries, 1312 Basehart SE, Albuquerque, NM 87106, USA CRAIG GUYER, Department of Biological Sciences, Auburn University, Auburn, AL 36849, USA ABSTRACT Recovery or sustainable management of wildlife populations often entails management of habitat on which they depend. In this regard, turtles pose unique conservation challenges because of their life histories. The combination of late maturity, low survival when young, and dependence on high adult survival suggests they may be slow to respond demographically to conventional habitat management. Thus, long- term studies are necessary to understand population dynamics and recovery potential in these species. -
Turtles of the Upper Mississippi River System
TURTLES OF THE UPPER MISSISSIPPI RIVER SYSTEM Tom R. Johnson and Jeffrey T. Briggler Herpetologists Missouri Department of Conservation Jefferson City, MO March 27, 2012 Background: A total of 13 species and subspecies of turtles are known to live in the Upper Mississippi River, its backwaters and tributaries. There are a few species that could be found occasionally, but would likely account for less than 5% of the species composition of any area. These species are predominantly marsh animals and are discussed in a separate section of this paper. For additional information on turtle identification and natural history see Briggler and Johnson (2006), Christiansen and Bailey (1988), Conant and Collins (1998), Ernst and Lovich (2009), Johnson (2000), and Vogt (1981). This information is provided to the fisheries field staff of the LTRM project so they will be able to identify the turtles captured during fish monitoring. The most current taxonomic information of turtles was used to compile this material. The taxonomy followed in this publication is the Scientific and Standard English Names of Amphibians and Reptiles of North America North of Mexico, with comments regarding confidence in our understanding (6th edition) by Crothers (2008). Species Identification, Natural History and Distribution: What follows is a synopsis of the 13 turtle species and subspecies which are known to occur in the Upper Mississippi River environs. Species composition changes between the upper and lower reaches of the LTRM study area (Wisconsin/Minnesota state line and southeastern Missouri) due to changes in aquatic habitats. For example, the Northern Map Turtle (Graptemys geographica) is abundant in the northern portion of the river with clearer water and abundant snail prey. -

North Louisiana Refuges Complex: Freshwater Turtle Inventory
NORTH LOUISIANA REFUGES COMPLEX: FRESHWATER TURTLE INVENTORY USFWS Award No: F17PX01556 John L. Carr, Aaron C. Johnson & J. Benjamin Grizzle November 2020 ACKNOWLEDGMENTS We thank the U.S. Fish and Wildlife Service Region 4 Inventory and Monitoring Branch for USFWS Award No. F17PX01556, “Freshwater Turtle Inventory of the North Louisiana Refuges Complex”. In addition, this report incorporates data from other, complementary projects that were funded by a variety of sources. This has been done in order to provide a more fulsome picture of knowledge on the turtle fauna of the refuges within the Complex. These other projects were funded in part by the Louisiana Department of Wildlife and Fisheries and the U.S. Fish and Wildlife Service, Division of Federal Aid, through the State Wildlife Grants Program (series of projects targeting the Alligator Snapping Turtle and map turtles). Other sources include data collected for grant activities funded by USGS-BRD (Cooperative Agreement No. 99CRAG0017), funding from the Louisiana Wildlife and Fisheries Foundation beginning in 1998, funding directly from LDWF (2000-2002), The Nature Conservancy (contract #LAFO_022309), Friends of Black Bayou, the Turtle Research Fund of the University of Louisiana at Monroe Foundation, and the Kitty DeGree Professorship in Biology (2011-2017). U.S. Fish and Wildlife personnel helped facilitate our work by granting access to all parts of the refuges at various times, and providing a series of Special Use Permits over 20+ years. We acknowledge Lee Fulton, Joe McGowan, Brett Hortman, Kelby Ouchley, and George Chandler for facilitating our work on refuges over the years; in particular, we thank Gypsy Hanks for long-sustained support and cooperation, especially during the course of the current project. -
