  • Prey Records for the Eastern Indigo Snake {Drymarchon Couperi)
    2010 SOUTHEASTERN NATURALIST 9(1):1-18 Prey Records for the Eastern Indigo Snake {Drymarchon couperi) Dirk J. Stevenson'*, M. Rebecca Bolt^ Daniel J. Smith', Kevin M. Enge^ Natalie L. Hyslop'^ Terry M. Norton'•^ and Karen J. Abstract - Prey items for the federally protected Easteni Indigo Snake (Drymarchort couperi) were compiled from published and gray literature, field observations, necrop- sies, dissection of museum specimens, and personal communications from reliable sources. One hundred and eighty-six records were obtained for 48 different prey spe- cies. Anurans, Gopher Tortoises, snakes, and rodents comprised ca. 85% of the prey items. Most records (n = 143) that mentioned size were from adult indigos; 17 were from juveniles. Prey records were collected from 1940-2008 and were available for all months of the year. These data confirm that Eastern Indigo Snakes eat a wide assortment of prey of varying sizes. This strategy allows D. couperi to potentially forage success- fully in many different types of habitats and under fluctuating environmental conditions, a valuable trait for a lop-level predator that requires a large home range. IatroducHon Drymarchon couperi Holbrook (Eastern Indigo Snake), with a maximum recorded total length of 2629 mm, is one of the largest snakes in North America (Conant and Collins 1991). It has been federally listed as Threat- ened since 1978 under the Endangered Species Act (US Fish and Wildlife Service 1978). Drymarchon couperi is diurnal and mostly terrestrial (Layne and Steiner 1996, US Fish and Wildlife Service 2008). Of the two main hunt- ing strategies employed by snakes (ambush predator vs. active forager; see Mushinsky 1987), D.

  • Contributions of Intensively Managed Forests to the Sustainability of Wildlife Communities in the South
    CONTRIBUTIONS OF INTENSIVELY MANAGED FORESTS TO THE SUSTAINABILITY OF WILDLIFE COMMUNITIES IN THE SOUTH T. Bently Wigley1, William M. Baughman, Michael E. Dorcas, John A. Gerwin, J. Whitfield Gibbons, David C. Guynn, Jr., Richard A. Lancia, Yale A. Leiden, Michael S. Mitchell, Kevin R. Russell ABSTRACT Wildlife communities in the South are increasingly influenced by land use changes associated with human population growth and changes in forest management strategies on both public and private lands. Management of industry-owned landscapes typically results in a diverse mixture of habitat types and spatial arrangements that simultaneously offers opportunities to maintain forest cover, address concerns about fragmentation, and provide habitats for a variety of wildlife species. We report here on several recent studies of breeding bird and herpetofaunal communities in industry-managed landscapes in South Carolina. Study landscapes included the 8,100-ha GilesBay/Woodbury Tract, owned and managed by International Paper Company, and 62,363-ha of the Ashley and Edisto Districts, owned and managed by Westvaco Corporation. Breeding birds were sampled in both landscapes from 1995-1999 using point counts, mist netting, nest searching, and territory mapping. A broad survey of herpetofauna was conducted during 1996-1998 across the Giles Bay/Woodbury Tract using a variety of methods, including: searches of natural cover objects, time-constrained searches, drift fences with pitfall traps, coverboards, automated recording systems, minnow traps, and turtle traps. Herpetofaunal communities were sampled more intensively in both landscapes during 1997-1999 in isolated wetland and selected structural classes. The study landscapes supported approximately 70 bird and 72 herpetofaunal species, some of which are of conservation concern.

  • Tail Bifurcation in Plestiodon Skiltonianus
    Herpetology Notes, volume 13: 343-345 (2020) (published online on 23 April 2020) Tail bifurcation in Plestiodon skiltonianus Danielle C. Miles1,*, Chasey L. Danser1, and Kevin T. Shoemaker1 Plestiodon skiltonianus (Smith, 2005), commonly The majority of tail bifurcations in other lizard species known as the Western Skink, is a smooth-scaled species are likely the result of abnormal tail regeneration after with a range from southern Idaho to northern Arizona in a lizard sheds its tail in response to a threat and are the Western United States (Tanner, 1957). The Western common across several lizard families (Clause et al. Skink is a part of the evolutionarily related skiltonianus 2006; Conzendey et al. 2013; Dudek & Ekner-Grzyb, group of lizards, of which none have previous records of 2014; Pelegrin & Leão, 2016; Tamar et al. 2013). Caudal tail bifurcation that we could find (Richmond & Reeder, 2002). Tail bifurcation is found in all of the major lizard groups and the most closely related species with this recorded observation is Plestiodon inexpectatus (Brandley et al, 2012; Koleska et al, 2017; Mitchell et al, 2012). On July 13 2019, one P. skiltonianus with a bifurcated tail was captured in a medium Sherman aluminium box trap designed for the live capture of small mammals that had been baited with bird seed and filled with biodegradable batting. As the traps were being collected at 17:00 PST, the malformed individual was found in the back of a trap, though the trap had not been triggered by its weight. The field site is at 39.4993°N, -117.0053°E on United States Forest Service land in Lander County northeast of Austin, Nevada, USA at an elevation of 1920 meters.

  • Summer Movements of the Common Five-Lined Skink (Plestiodon Fasciatus) in the Northern Portion of Its Range
    Herpetological Conservation and Biology 13(3):743–752. Submitted: 3 July 2018; Accepted: 25 November 2018; Published: 16 December 2018. SUMMER MOVEMENTS OF THE COMMON FIVE-LINED SKINK (PLESTIODON FASCIATUS) IN THE NORTHERN PORTION OF ITS RANGE DANIEL J. BRAZEAU1 AND STEPHEN J. HECNAR1,2 1Department of Biology, Lakehead University, 955 Oliver Road, Thunder Bay, Ontario, P7B 5E1, Canada 2Corresponding author, e-mail: [email protected] Abstract.—Common Five-lined Skinks (Plestiodon [formerly Eumeces] fasciatus) are difficult to study due to their small size, secretive habits, and semi-fossorial natural history. Habitat selection and dispersal have been studied at several locations across the range of the species, but few details of movements are known. Our objectives were to use radio-telemetry to gain more insight into skink movements and to test the efficacy of small, lightweight transmitters that we externally attached. We fitted 31 skinks with transmitters that provided up to 16 consecutive days of dispersal information. Movements varied greatly among individuals with some staying close to initial capture sites while most moved tens to hundreds of meters over a short period of observation. We located most of the tracked individuals under cover of woody debris but found they were much more mobile than previous mark- recapture studies suggested. Our tracking supported the idea that traditional home ranges were not occupied, but instead most individuals made regular linear movements while returning to the same locations occasionally. Individuals spent on average just over 30% of their time underground, in grass tussocks, and inside standing trees near the end of the active season.

JAKE S. MORRISSEY1, BRANDON BARR1, ANDREW E. AUSTIN1, LAUREN R. BABCOCK1, AND ROBERT POWELL1,2 1Department of Biology, Avila University, Kansas City, Missouri 64145, USA 2Corresponding author. E-mail: [email protected] ABSTRACT: Common Five-lined Skinks (Plestiodon fasciatus) have an extensive distribution that in- cludes much of eastern North America. We examined 490 female specimens (274 with putative clutch sizes) from throughout the range to see if latitude, elevation, mean annual temperature, and/or mean annual precipitation affected body or clutch sizes. We predicted that larger females would produce larger clutches, latitude and elevation would negatively affect both body and clutch sizes, and that temperature and precipitation would exert a positive effect. Our results did not consistently support those predictions. Body size was positively associated with latitude, negatively associated with tem- perature, and not associated with elevation or precipitation. Clutch size was not related to female body size, but in most instances was positively associated with temperature and precipitation but negatively associated with elevation and latitude. EffectivelyK -selected in the North and r-selected in the South, body and clutch sizes in this species appear to be responding to different selective pressures. We eval- uated probable causes for the opposite trends in these two life-history traits. Key Words: Bergmann’s rule; r- and K-selection; Resource rule; Temperature-size rule.

Turner ii ABSTRACT A major obstacle to the preservation of animal populations is habitat fragmentation. Fragmentation often results in the isolation and subsequent loss of subpopulations. Gene flow determines the extent to which populations remain separated as independent evolutionary units, and thus affects the evolution of a species. Gene flow between small fragmented subpopulations can often have great effects on the species stability. If small populations are lost and there is no migration between subpopulations, recolonization of suitable habitat does not occur and the overall population declines. The loss of naturally occurring populations reduces gene flow, which may lead to genetic differentiation. This study investigated the population structure of the five-lined skink, Eumeces fasciatus, occupying what appear to be isolated sites in the fragmented landscape of Northeast Ohio. Populations in Akron were of particular interest because they exist in highly urbanized locales, and these lizards have rarely been recorded in Summit County. Additionally, there is a large gap in distribution record of the species statewide.

  • Status and Conservation of the Reptiles and Amphibians of the Bermuda Islands
    Status and conservation of the reptiles and amphibians of the Bermuda islands Jamie P. Bacon1,2, Jennifer A. Gray3, Lisa Kitson1 1 Bermuda Zoological Society, Flatts FL 04, Bermuda 2 Corresponding author; email: [email protected] 3 Bermuda Government Department of Conservation Services, Flatts FL 04, Bermuda Abstract. Bermuda’s herpetofauna includes three species of amphibians, one fossil tortoise, two species of freshwater turtles, five species of marine turtles, and four species of lizards. The amphibians Eleutherodactylus johnstonei, E. gossei and Bufo marinus were all introduced in the late 1880s. Amphibian population declines, including the possible extirpation of E. gossei, prompted the initiation in 1995 of an on-going investigation. Research into the high deformity rates in B. marinus has indicated that survival and development of larvae are affected by contaminants in a number of ponds and by the transgenerational transfer of accumulated contaminants. Of the two emydid turtles in Bermuda, Malaclemys terrapin may be native and its population characteristics are being studied; Trachemys scripta elegans is considered invasive and efforts are underway to remove its populations from the wild. The sizeable resident Chelonia mydas population has been the focus of a mark- recapture study since 1968. Results indicate that Bermuda is currently an important developmental habitat for green turtles originating from at least four different nesting beaches in the Caribbean. Immature Eretmochelys imbricata also reside on the Bermuda Platform and genetics studies suggest that multiple Caribbean genotypes are represented in Bermuda’s hawksbill population. Caretta caretta do not appear to be regular inhabitants, but two known loggerhead nesting events have recently occurred (in 1990 and 2005) and post-hatchling loggerheads regularly strand after winter storms.
