Herpetological Review
Herpetological Review FARANCIA ERYTROGRAMMA (Rainbow Snake). HABITAT. Submitted by STAN J. HUTCHENS (e-mail: [email protected]) and CHRISTOPHER S. DEPERNO, (e-mail: [email protected]), Fisheries and Wildlife Pro- gram, North Carolina State University, 110 Brooks Ave., Raleigh, North Carolina 27607, USA. canadensis) dams reduced what little fl ow existed in some canals to standing quagmires more representative of the habitat selected by Eastern Mudsnakes (Farancia abacura; Neill 1964, op. cit.). Interestingly, one A. rostrata was observed near BNS, but none was captured within the swamp. It is possible that Rainbow Snakes leave bordering fl uvial habitats in pursuit of young eels that wan- dered into canals and swamp habitats. Capturing such a secretive and uncommon species as F. ery- trogramma in unexpected habitat encourages consideration of their delicate ecological niche. Declining population indices for American Eels along the eastern United States are attributed to overfi shing, parasitism, habitat loss, pollution, and changes in major currents related to climate change (Hightower and Nesnow 2006. Southeast. Nat. 5:693–710). Eel declines could negatively impact population sizes and distributions of Rainbow Snakes, especially in inland areas. We believe future studies based on con- fi rmed Rainbow Snake occurrences from museum records or North Carolina GAP data could better delineate the range within North Carolina. Additionally, sampling for American Eels to determine their population status and distribution in North Carolina could augment population and distribution data for Rainbow Snakes. We thank A. Braswell, J. Jensen, and P. Moler for comments on earlier drafts of this manuscript. Submitted by STAN J. HUTCHENS (e-mail: [email protected]) and CHRISTOPHER S. -
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. -
COTTONMOUTH Agkistrodon Piscivorus
COTTONMOUTH Agkistrodon piscivorus Agkistrodon is derived from ankistron and odon which in Greek mean “fishhook” and “tooth or teeth;” referring to the curved fangs of this species. Piscivorus is derived from piscis and voro which in Latin mean “fish” and “to eat”. Another common name for cottonmouth is water moccasin. The Cottonmouth is venomous. While its bite is rarely fatal, tissue damage is likely to occur and can be severe if not treated promptly. IDENTIFICATION Appearance: The cottonmouth is a stout- bodied venomous snake that reaches lengths of 30 to 42 inches as adults. Most adults are uniformly dark brown, olive, or black, tending to lose the cross banded patterning with age. Some individuals may have a dark cheek stripe (upper right image). The cottonmouth has the diagnostic features of the pit-viper family such as a wedge-shaped head, sensory pits between the eyes and nostrils, and vertical “cat-like” pupils. Juveniles are lighter and more boldly patterned with a yellow coloration toward the tip of the tail (lower right image). Dorsal scales are weakly keeled, and the subcaudal scales form only one row. Cottonmouths also have a single anal Mike Redmer plate. Subspecies: There are three subspecies of the cottonmouth. The Western Cottonmouth (A. p. leucostoma) is the only subspecies found in the Midwest. The term leucostoma refers to the white interior of mouth. Confusing Species: The non-venomous watersnakes (Nerodia) are commonly confused with Cottonmouths across their range, simply because they are snakes in water. Thus it is important to note that Cottonmouths are only found in southernmost Midwest. -
Northern Watersnake Selection of Fish Prey in Western Kentucky
Northern Watersnake Diet . Perkins and Eason Northern Watersnake Selection of Fish Prey in Western Kentucky Micah W. Perkins 1, Department of Biology, University of Louisville, 139 Life Sciences Building, Louisville, KY 40292 Perri K. Eason, Department of Biology, University of Louisville, 139 Life Sciences Building, Louisville, KY 40292 Abstract: Watersnakes serve a variety of important roles in aquatic ecosystems with many species being of conservation interest. The northern water- snake (Nerodia sipedon) has some populations of concern, but is found in a wide variety of aquatic habitats throughout North America. Although pre- vious studies have examined the diet of this typically piscivorous species, research has not addressed whether the northern watersnake is preferentially selecting particular fish as prey. In this study, we sampled snake stomach contents and used Chesson’s alpha selection index α( i) to investigate whether northern watersnakes are eating fish families in proportion to their availability or are preferentially selecting or avoiding specific fish families. At the Sloughs Wildlife Management Area in western Kentucky, the northern watersnake fed on fish from six families in 2013 (n = 15) and 2014 (n = 36). Five of those fish families were eaten in proportion to their availability but avoided pirate perch (Aphredoderus sayanus), the lone member of the family Aphredoderidae. This is the first study testing prey preferences in the northern watersnake. Key words: northern watersnake, Nerodia sipedon, diet selection, fish family, pirate perch Journal of the Southeastern Association of Fish and Wildlife Agencies 5:144–149 Many watersnakes are of conservation concern and can poten- igan shifted from a heavily amphibian-based diet to feeding only on tially be used as indicators to understand harmful human impacts fishes (Meyer 1992, Carbone 1993). -
Hybridization Between Multiple Fence Lizard Lineages in an Ecotone
Molecular Ecology (2007) 16, 1035–1054 doi: 10.1111/j.1365-294X.2006.03194.x HybridizationBlackwell Publishing Ltd between multiple fence lizard lineages in an ecotone: locally discordant variation in mitochondrial DNA, chromosomes, and morphology ADAM D. LEACHÉ* and CHARLES J. COLE†‡ *Museum of Vertebrate Zoology and Department of Integrative Biology, 3101 Valley Life Sciences Building, University of California, Berkeley, CA 94720-3160, USA, †Department of Herpetology, American Museum of Natural History, New York, NY 10024-5192, USA Abstract We investigated a hybrid zone between two major lineages of fence lizards (Sceloporus cowlesi and Sceloporus tristichus) in the Sceloporus undulatus species complex in eastern Arizona. This zone occurs in an ecotone between Great Basin Grassland and Conifer Wood- land habitats. We analysed spatial variation in mtDNA (N = 401; 969 bp), chromosomes (N = 217), and morphology (N = 312; 11 characters) to characterize the hybrid zone and assess species limits. A fine-scale population level phylogenetic analysis refined the boundaries between these species and indicated that four nonsister mtDNA clades (three belonging to S. tristichus and one to S. cowlesi) are sympatric at the centre of the zone. Esti- mates of cytonuclear disequilibria in the population closest to the centre of the hybrid zone suggest that the S. tristichus clades are randomly mating, but that the S. cowlesi haplotype has a significant nonrandom association with nuclear alleles. Maximum-likelihood cline- fitting analyses suggest that the karyotype, morphology, and dorsal colour pattern clines are all coincident, but the mtDNA cline is skewed significantly to the south. A temporal comparison of cline centres utilizing karyotype data collected in the early 1970s and in 2002 suggests that the cline may have shifted by approximately 1.5 km to the north over a 30-year period. -
