Available in PDF, EPUB and Kindle. Book excerpt: Three research projects were conducted to further our understanding of the physiological adaptations that promote survival of terrestrially-hibernating hatchling turtles. Unit I, Cold Hardiness of Hatchlings of the Diamondback Terrapin examines the functional basis for cold hardiness in hatchlings of the diamondback terrapin, Malaclemys terrapin, a species that may hibernate terrestrially in the northern portion of its range. Hatchlings subjected to experimental freezing survived exposure to temperatures as low as -3.0°C, suggesting that freeze tolerance may account for the high winter survival observed in natural nests. Freeze tolerance in hatchling M. terrapin is promoted by high susceptibility to inoculation, which is known to promote slow freezing allowing cells time to adapt to the attendant physical and osmotic stresses. Unit II, Oxidative Stress and Antioxidant Capacity of a Terrestrially-hibernating Hatchling Turtle examines the role of endogenous antioxidants in preventing oxidative damage following periods of supercooling and freezing in hatchling Chrysemys picta. The results of this study suggest that hatchling C. picta have a well-developed antioxidant defense system that minimizes oxidative damage during hibernation. Unit III, Asynchrony in the Timing of Emergence from the Nest by Hatchlings of Freshwater Turtles describes the timing of emergence from the nest by hatchling turtles. Average date of fall emergence from the nest did not vary among species; however, a species-specific pattern of emergence in spring was observed. Chrysemys picta emerged in late March and early April and, on average, these hatchlings left their nests two weeks earlier than G. geographica and four weeks earlier than T. scripta. Hatchlings of C. picta overwintered in nests that were shallow relative to the other terrestrially-hibernating species, and minimum nest temperatures were significantly lower in winter. Although hatchlings of C. picta are smaller than those of G. geographica and T. scripta, they can gain a survival and/or growth advantage by emerging earlier. The fitness benefits of early emergence may lead to the improvement of cold-hardiness adaptations in northern populations of turtles.

Available in PDF, EPUB and Kindle. Book excerpt: Trundling along in essentially the same form for some 220 million years, turtles have seen dinosaurs come and go, mammals emerge, and humankind expand its dominion. Is it any wonder the persistent reptile bested the hare? In this engaging book physiologist Donald Jackson shares a lifetime of observation of this curious creature, allowing us a look under the shell of an animal at once so familiar and so strange. Here we discover how the turtle’s proverbial slowness helps it survive a long, cold winter under ice. How the shell not only serves as a protective home but also influences such essential functions as buoyancy control, breathing, and surviving remarkably long periods without oxygen, and how many other physiological features help define this unique animal. Jackson offers insight into what exactly it’s like to live inside a shell—to carry the heavy carapace on land and in water, to breathe without an expandable ribcage, to have sex with all that body armor intervening. Along the way we also learn something about the process of scientific discovery—how the answer to one question leads to new questions, how a chance observation can change the direction of study, and above all how new research always builds on the previous work of others. A clear and informative exposition of physiological concepts using the turtle as a model organism, the book is as interesting for what it tells us about scientific investigation as it is for its deep and detailed understanding of how the enduring turtle “works.”

Download or read book Queensland's Threatened Animals written by Lee K Curtis and published by CSIRO PUBLISHING. This book was released on 2012-02-01 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Queensland is home to 70% of Australia’s native mammals (226 species), over 70% of native birds (630 species), just over half of the nation’s native reptiles (485) and native frogs (127), and more than 11 000 native plant species. Hundreds of these have a threatened status in Queensland. In order for Queensland to maintain and recover a healthy biodiversity we must address the serious problems faced by our natural environment – habitat loss, inappropriate land management, change in fire regimes, pollution of natural resources, proliferation of invasive species and climate change. This book features up-to-date distribution data, photos and maps for most of Queensland’s threatened animals. It also includes a comprehensive list of resources, with key state, national and international organisations involved in the recovery and management of threatened species. Queensland's Threatened Animals will provide vital information to scientists, educators, business entities, government agencies, students, community groups, environmental NGOs, regional NRMs and potential volunteers.

Book excerpt: The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.

Book excerpt: This book is not a conventional review of diving physiology. The coverage of the literature has been selective rather than en compassing, the emphasis has been on field studies rather than laboratory investigations, and the dive responses described are often discussed from the perspective of some of the flaws or weaknesses in the conclusions. Some of these points are of more historical interest to note how our concepts have evolved as we learn more about behavior and responses to natural diving in contrast to forced submersions in the laboratory. As a result there is a degree of evaluation of some experiments on my part that may seem obvious or controversial to the specialist. I have followed this planat times in order to aid the reader, who I hope is often an untergraduate or graduate stu dent, the nonspecialist, and the layman, in appreciating to some degree the level of dissatisfaction or skepticism about certain areas of research in diving physiology. In view of historical boundaries in vertebrate biology, the subject is of broad enough importance to catch the interest of a wide audience of readers if I have done my job well. For ex ample, of the major epochal transitions or events there have been in vertebrate history, three come immediately to mind: (1) The transition from aquatic to aerial respiration which ultimately led to a broad occupation of terrestrial habitats. (2) The development of endothermy.
