Download or read book Chemical Signals in Vertebrate Predator prey Systems Involving Common Musk Turtles Sternotherus Odoratus Cottonmouths Agkistrodon Piscivorus and Common Snapping Turtles Chelydra Serpentina written by Neil Dazet and published by . This book was released on 2010 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical secretions from the Rathke's glands of common musk turtles have a variety of proposed functions including predator deterrence and attraction, but experimental studies testing these hypotheses are lacking. This study used laboratory and field experiments to test whether musk secretions had attraction or repellent effects on two natural predators, the cottonmouth (Agkistrodon piscivorus), and the common snapping turtle (Chelydra serpentina). In a laboratory experiment, I examined latency to feed and consumption times for cottonmouths offered musk-treated minnows and control minnows. In a field study, I investigated the ratio of snapping turtles appearing in traps with and without musk-treated bait. The latency to feed times for cottonmouths offered musk-treated minnows were not significantly different from those offered control minnows. However, prey consumption times for cottonmouths feeding on musk-treated minnows were significantly greater than those feeding on control minnows. These results suggest that the musk secretions may lengthen the time of a predation sequence, possibly allowing the turtle more time to escape from the predator. The number of snapping turtles appearing in traps with musk-treated bait was significantly greater than the number of snapping turtles in traps without musk-treated bait. These results support the predator attraction hypothesis, where the signal may attract additional predators that interfere with a predation event, providing an opportunity for the prey to escape.

This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that the recent progress in molecular and cellular biology would not have been possible without an understanding of the mechanisms and signaling pathways of communication inside the cell and between various cells of the animal organism. In fact a similar progress occurred in the field of chemical communication between individual organisms of vertebrate species, and this volume is aimed at presenting the current state of the art on this subject. The reader can find here both original results obtained in the laboratory or field studies and comprehensive reviews summarizing many years of research. The presentations of over 60 scientists have been grouped according to their approach into nine parts covering such fields as ecological and evolutionary aspects of chemical communication, structure and neuronal mechanisms of chemosensory systems, chemical structure of pheromones and binding proteins, kin, individual and sexual recognition, predator-prey relationships, purpose and consequences of marking behavior, scent signals and reproductive processes. Expanding on former volumes of this series, entirely new chapters have been added on prenatal chemical communication describing specific effects of the intrauterine environment. In many cases a truly multidisciplinary approach was required, such as with the population analysis of polymorphic variants of the mouse's major urinary proteins that function in carrying pheromones.

Download or read book Feeding in Vertebrates written by Vincent Bels and published by Springer. This book was released on 2019-04-23 with total page 865 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides students and researchers with reviews of biological questions related to the evolution of feeding by vertebrates in aquatic and terrestrial environments. Based on recent technical developments and novel conceptual approaches, the book covers functional questions on trophic behavior in nearly all vertebrate groups including jawless fishes. The book describes mechanisms and theories for understanding the relationships between feeding structure and feeding behavior. Finally, the book demonstrates the importance of adopting an integrative approach to the trophic system in order to understand evolutionary mechanisms across the biodiversity of vertebrates.
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.
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.

Download or read book Malformed Frogs written by Michael Lannoo and published by Univ of California Press. This book was released on 2008-08-04 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread appearance of frogs with deformed bodies has generated much press coverage over the past decade. Frogs with extra limbs or digits, missing limbs or digits, or misaligned appendages raise an alarming question: "Are deformed humans next?" Taking a fresh look at this disturbing environmental problem, this reference provides a balanced overview of the science behind the malformed frog phenomenon. Bringing together data from ecology, parasitology, and other disciplines, Michael Lannoo considers the possible causes of these deformities, tells which frogs have been affected, and addresses questions about what these malformations might mean to human populations. Featuring high-quality radiographic images, Malformed Frogs suggests that our focus should be on finding practical solutions, a key component of which will be controlling chemical, nutrient, and pesticide runoff into wetlands.
Download or read book Migration written by Hugh Dingle and published by Oxford University Press. This book was released on 2014 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Migration, broadly defined as directional movement to take advantage of spatially distributed resources, is a dramatic behaviour and an important component of many life histories that can contribute to the fundamental structuring of ecosystems. In recent years, our understanding of migration has advanced radically with respect to both new data and conceptual understanding. It is now almost twenty years since publication of the first edition, and an authoritative and up-to-date sequel that provides a taxonomically comprehensive overview of the latest research is therefore timely. The emphasis throughout this advanced textbook is on the definition and description of migratory behaviour, its ecological outcomes for individuals, populations, and communities, and how these outcomes lead to natural selection acting on the behaviour to cause its evolution. It takes a truly integrative approach, showing how comparisons across a diversity of organisms and biological disciplines can illuminate migratory life cycles, their evolution, and the relation of migration to other movements. Migration: The Biology of Life on the Move focuses on migration as a behavioural phenomenon with important ecological consequences for organisms as diverse as aphids, butterflies, birds and whales. It is suitable for senior undergraduate and graduate level students taking courses in behaviour, spatial ecology, 'movement ecology', and conservation. It will also be of interest and use to a broader audience of professional ecologists and behaviourists seeking an authoritative overview of this rapidly expanding field.

Download or read book Intersexuality in the Animal Kingdom written by R. Reinboth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Richard Goldschmidt' coined the term "intersexuality" in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters. However, as knowledge of the bewildering variability present in the sexual orga nization of members of the animal kingdom has increased, the original meaning of the word has changed. Today many authors define inter sexuality as "the presence of both male and female characteristics, or of intermediate sexual characteristics, in a single individual".2 This more extensive and widely accepted concept justifies the title of our book •. Among all the anatomical and physiological features of living organisms the reproductive system has a unique importance for the perpetuation of the species. Conversely, reproductive processes are of little or no account for the viability of the individual. Therefore, within the framework of general biology reproduction has all too often been looked at solely from the point of view of genetics. Lively discussions about genotypic versus phenotypic sex determination long dominated the sci entific literature on sexuality in animals; this one-sided emphasis has tended to obscure many important facets of an organism's ability to reproduce. Recent developments in current biological research have brought the classic problem of sex differentiation into focus again, and the rapid progress being made in comparative endocrinology has added a new di mension to the study of reproductive biology.
