Book excerpt: ABSTRACT Spiny softshell turtles (Apalone spinifera) occur at the northwest limit of their range in Lake Champlain. This species, although widespread across North America, is listed as threatened in Vermont due to habitat destruction and disturbances of anthropogenic origin. The population of spiny softshell turtles in Lake Champlain is isolated from other North American populations and is considered as an independent management unit. Efforts to obtain information on the biology of spiny softshell turtles in Lake Champlain precede 1936 with conservation measures being initiated in 1987. Methods of studying spiny softshell turtles in Lake Champlain have included direct observation, mark-recapture, nest beach monitoring, winter diving, and radio telemetry. Each of these approaches has provided some information to the sum of what is known about A. spinifera in Lake Champlain. For example major nesting beaches, hibernacula, and home range size have been determined. Currently spiny softshell turtles primarily inhabit two areas within Lake Champlain, Missisquoi Bay and the mouth of the Lamoille River. However, the population structure and gene flow between spiny softshell turtles inhabiting the Lamoille and Missisquoi regions remained unknown. A GIS model was created and tested in order to identify additional nesting beaches used by spiny softshell turtles along the Vermont shores of Lake Champlain. Although some additional small potential nesting beaches were found, no additional major nesting sites were found. The GIS model identified the mouth of the Winooski River (the site of a historical population) as potentially suitable nesting habitat; however, no evidence of spiny softshell turtle nesting was found at this site. A series of methods developed for collecting molecular and population genetic data about spiny softshell turtles in Lake Champlain are described, including techniques for DNA extraction of various tissue types and the design of new primers for PCR amplification and sequencing of the mitochondrial control region (mtD-loop). Techniques for circumventing problems associated with DNA sequence alignment in regions of a variable numbers of tandem repeats (VNTRs) and the presence of heteroplasmy within some individuals are also described. The mtD-loop was found to be a suitable marker to assess the genetic structure of the Lake Champlain population of spiny softshell turtles. No significant genetic sub-structuring was found (FST=0.082, p=0.223) and an indirect estimate of the migration rate between Lamoille and Missisquoi regions of Lake Champlain was high (Nm>5.576). In addition to consideration of A. spinifera in Lake Champlain, the mtD-loop was modeled across 46 species in 14 families of extant turtles. The primary structure was obtained from DNA sequences accessed from GenBank and secondary structures of the mtD-loop were inferred, (from thermal stabilities) using the program Mfold, for each superfamiliy of turtles. Both primary and secondary structures were found to be highly variable across the order of turtles; however, the inclusion of an AT-rich fold (secondary structure) near the 3' terminus of the mtD-loop was common across all turtle families considered. The Cryptodira showed conservation in the primary structure at regular conserved sequence blocks (CSBs), but the Pluerodira displayed little conservation in the primary structure of the mtD-loop. Overall, greater conservation in secondary structure than primary structure was observed in turtle mtD-loop. The AT-rich secondary structural element near the 3' terminus of the mtD-loop may be conserved across turtles due to it serving a functional role during mtDNA transcription.

Available in PDF, EPUB and Kindle. Book excerpt: Winner, 2011 Book Award, The Wildlife Society2009 Outstanding Academic Title, Choice Ernst and Lovich’s thoroughly revised edition of this classic reference provides the most updated information ever assembled on the natural histories of North American turtles. From diminutive mud turtles to giant alligator snappers, two of North America’s most prominent experts describe the turtles that live in the fresh, brackish, and marine waters north of Mexico. Incorporating the explosion of new scientific information published on turtles over the past fifteen years—including the identification of four new species—Ernst and Lovich supply comprehensive coverage of all fifty-eight species, with discussions of conservation status and recovery efforts. Each species account contains information on identification, genetics, fossil record, distribution, geographic variation, habitat, behavior, reproduction, biology, growth and longevity, food habits, populations, predators, and conservation status. The book includes range maps for freshwater and terrestrial species, a glossary of scientific names, an extensive bibliography for further research, and an index to scientific and common names. Logically organized and richly illustrated—with more than two hundred color photographs and fifty-two maps—Turtles of the United States and Canada remains the standard for libraries, museums, nature centers, field biologists, and professional and amateur herpetologists alike.

This book was released on 2017-03-07 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Softshell turtles are among the most unique chelonians in the world. They're myriad physical and behavioral adaptations provide a nice contrast with those of most commonly kept turtle species, and yet, relatively few keepers work with these amazing animals. While softshell turtles are not ideal for all keepers, they do adapt well to captivity when provided with suitable accommodations, proper temperatures and clean water. They reach impressive sizes and have defensive demeanors, so they are not appropriate for beginners or those unable to provide them with enough space. However, for those who can provide these requirements, and have the necessary skill, dedication and resources, softshell turtles are very intriguing pets. As when caring for any animal as a pet, keepers must learn as much as possible about the biology, behavior and ecology of softshell turtles, in order to provide them the highest quality of life possible. Begin that journey inside, by learning about these interesting turtles, their place in the world and how to provide them with an artificial habitat that meets their needs. The author, Ben Team, is an environmental educator and author with over 16 years of professional reptile-keeping experience. Ben currently maintains www.FootstepsInTheForest.com, where he shares information, narration and observations of the natural world. When not writing about plants, animals and habitats, Ben enjoys spending time with his beautiful wife. Covered in this book: - Acquiring - Anatomy - Behavior - Biology - Breeding - Captive considerations - Daily care - Description - Diet - Ecology - Enclosure - Health - Husbandry - Interacting - Lighting - Maintenance - Monitoring - Myths and Misunderstandings - Taxonomy - The ideal environment .... and much more

This book was released on 2016 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The continuing decline of this species in Ontario and Québec is attributed to very low recruitment that has resulted from loss of nesting habitat. Suitable nesting and basking sites have been lost and/or degraded by development, altered water regimes (e.g., dams, floods, erosion of river banks), invasive plants, recreational use, and illegal harvest of individuals. Without nest protection, few eggs survive predation by an increased abundance of mammals. Designated Threatened in April 1991. Status re-examined and confirmed in May 2002. Status re-examined and designated Endangered in April 2016"--Assessment summary, p. iii.
