Book Synopsis Effects of Hydric Conditions Experienced by Incubating Red-eared Slider Turtle Eggs, Trachemys Scripta Elegans, on Overwintering Hatchlings and Their Survivorship Upon Emerging from the Nest by : Nirvana Iolani Filoramo
Download or read book Effects of Hydric Conditions Experienced by Incubating Red-eared Slider Turtle Eggs, Trachemys Scripta Elegans, on Overwintering Hatchlings and Their Survivorship Upon Emerging from the Nest written by Nirvana Iolani Filoramo and published by . This book was released on 1997 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This behavior appears to lessen the impact of predation by birds. Predation has been indicated as a mechanism for driving the selection for larger body size. Therefore, reduction in mortality due to avian predators may have been the cause for not finding any effect of body size on survivorship, as had been found in past studies.
Book Synopsis Effects of the Developmental Environment on Oxidative Damage and Antioxidants in Red-eared Slider Turtle (Trachemys Scripta Elegans) Hatchlings by : Lisa A. Treidel
Download or read book Effects of the Developmental Environment on Oxidative Damage and Antioxidants in Red-eared Slider Turtle (Trachemys Scripta Elegans) Hatchlings written by Lisa A. Treidel and published by . This book was released on 2015 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developmental environments influence many individual phenotypes. However, currently we have a limited understanding of how the developmental environment influences oxidative stress resistance phenotypes. Oxidative stress is defined as a physiological state during which the production of harmful free radicals exceeds the protective capabilities of antioxidants. Variations among adults in susceptibility to oxidative stress can have important consequences for life history strategies and fitness related traits. Our work was aimed at providing insight in to the role that the developmental environment plays on oxidative stress phenotypes in the model oviparous reptile the red-eared slider turtle (Trachemys scripta elegans). Here, we conducted three independent experiments to determine if hatchling levels of oxidative damage and antioxidant activities vary following manipulations of the incubation thermal environment. First, to investigate if temperature fluctuations elicit oxidative stress during incubation, eggs from clutches were randomly assigned to a constant temperature (29.5℗ʻC) or daily sinusoidal fluctuating temperature incubation (28.7+3℗ʻC) treatment. Second, to assess the effect of temperature fluctuation frequency on oxidative stress, eggs were incubated in one of three fluctuating incubation regimes; 28.7+3℗ʻC sinusoidal fluctuations every 12 (Hyper), 24 (Normal), or 48 hours (Hypo). Third, we tested the influence of average incubation temperature on hatchling oxidative damage and total antioxidant capacity (TAC). To test this, eggs were incubated in daily sinusoidally fluctuating incubation temperature regime with a mean temperature of 26.5 ℗ʻ C (Low), 27.1 ℗ʻC (Medium), or 27.7 ℗ʻC (High). We report that regardless of any thermal manipulation, no treatment effects on hatchling accumulation of oxidative damage were observed. This finding suggests that T. scripta hatchlings have sufficient antioxidant defenses that effectively protect individuals from temperature induced oxidative stress during incubation. However, hatchling TAC was influenced by both temperature fluctuation frequency and average incubation temperature. Following incubation with a low frequency of temperature fluctuations individuals had a reduced TAC, while incubation at a lower average temperature was associated with enhanced TAC. These results indicate that hatchling TAC is likely sensitive to the developmental thermal environment and may have important future consequences for hatchling fitness. In addition to temperature, we also saw that both oxidative damage and TAC were significantly related to clutch identity suggesting that there are either strong maternal or genetic factors influencing early life oxidative status of T. scripta.
Book Synopsis Herpetological Osteopathology by : Bruce M. Rothschild
Download or read book Herpetological Osteopathology written by Bruce M. Rothschild and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.
Book Synopsis Biological Invasions and Its Management in China by : Fanghao Wan
Download or read book Biological Invasions and Its Management in China written by Fanghao Wan and published by Springer. This book was released on 2017-04-25 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses invasive-species problems in agriculture, forests and aquatic ecosystems, highlighting the invasive mechanisms and management of the selected invasive species. Biological invasion has become a serious global ecological and economic problem that deserves particular attention from both government officials and scientists. This volume focuses on three key scientific areas: 1) population establishment and spreading mechanisms of the selected invasive species; 2) ecology adaptation, population growth, expansion and evolution of invasive species; and 3) impact of bio-invasion on the ecosystem structure and function at community and ecosystem levels. The presented research will result in techniques for better management of invasive species.

Book Synopsis Health and Welfare of Captive Reptiles by : Clifford Warwick
Download or read book Health and Welfare of Captive Reptiles written by Clifford Warwick and published by Springer Nature. This book was released on 2023-01-24 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively revised and expanded new edition offers concepts, principles and applied information that relates to the wellbeing of reptiles. As a manual on health and welfare in a similar vein to volumes addressing the sciences of anatomy, behaviour or psychology, this book thoroughly examines the biology of reptile welfare and is about meeting biological needs. The editors, acknowledged experts in their own right, have once again drawn together an extremely impressive international group of contributors. Positive and negative implications of general husbandry and research programs are discussed. In addition to greatly revised original content are nine new chapters offering readers novel insight into: • sensory systems • social behaviour • brain and cognition • controlled deprivation and enrichment • effects of captivity-imposed noise and light disturbance on welfare • spatial and thermal factors• evidential thresholds for species suitability in captivity • record keeping as an aid to captive care • arbitrary husbandry practices and misconceptions The authors have adopted a user-friendly writing style to accommodate a broad readership. Although primarily aimed at academic professionals, this comprehensive volume is fundamentally a biology book that will also inform all involved in captive reptile husbandry. Among others, zoo personnel, herpetologists, veterinarians, lab animal scientists, and expert readers in animal welfare and behavioural studies will benefit from this updated work.
