Download or read book Amphibian and Reptile Adaptations to the Environment written by Denis Vieira de Andrade and published by CRC Press. This book was released on 2017-12-19 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their diversity, amphibians and reptiles share many physiological traits, such as their dependence on external heat sources for body temperature regulation, that are of pivotal importance to their ability to cope with the environment. Considerable variation in physiological capabilities exists in these groups and often can be related to seasonal and geographic differences in environmental parameters. This book provides a comprehensive and integrative view of the interplay between physiology and behavior in amphibians and reptiles, leading to a better understanding of the subject. The book covers topics that have recently been in the spotlight for scientific research on the physiology, behavior, and conservation of amphibians and reptiles. It brings together recent information from a range of disciplines that address critical topics for understanding their biology. As these studies are scattered across articles in specialized journals, this book provides a single and expanded source summarizing such advancements. Amphibian and Reptile Adaptations to the Environment: Interplay Between Physiology and Behavior maintains a solid scientific basis for the biological topics covered. However, it presents the material in a clear and direct manner so that it is accessible even to non-biologists interested in the basic biology, behavior, and ecology of these animals as well as how these elements are connected to their conservation.

Download or read book The Ecology and Behavior of Amphibians written by Kentwood D. Wells and published by University of Chicago Press. This book was released on 2010-02-15 with total page 1162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

Download or read book Environmental Physiology of Animals written by Pat Willmer and published by Wiley-Blackwell. This book was released on 2000-02-28 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new text provides a fresh approach to the subject of animal physiology, truly integrating comparative and environmental aspects for the first time. The book is divided into three sections: the first covers the basic principles of adaptation and problems of size and scale; the second tackles the key mechanisms in comparative physiology; and the third considers in detail how organisms (both vertebrate and invertebrate) cope with particular environments. Throughout this final section, relevant comparative aspects are given prominence in boxes so that interesting topics can be explored in greater depth. Several textbooks deal with the physiological functioning and comparative adaptations of animals, but this one is different: Includes both comparative systems physiology (basic principles and mechanisms of excretion, thermal biology, respiration, etc) and environmental physiology (problems of life in different habitats), with easy cross-reference between the two. Analyses and integrates problems and adaptations for each kind of environment: marine, seashore and estuary, freshwater, terrestrial and parasitic. For example, it explains how seashore animals survive both tidal submersion in cold salt water and exposure to warm dry air, cope with wide variations in salinity and temperature and achieve both aerial and underwater breathing. Examines mechanisms and responses beyond physiology. It analyses the costs of different types of locomotion, together with the mechanical challenges and varying sensory needs imposed by different environments. Behavioural responses to environmental challenges are considered, including the evolution of mating systems and life-history strategies, as well as responses to stresses imposed by humans. The book therefore integrates the biochemical, physiological, behavioral and ecological adaptations that allow animals to survive in particular environments. Applies an evolutionary perspective to the analysis of environmental adaptation. It introduces modern, phylogeny-based comparative methods that have become standard techniques in the analysis of evolutionary patterns. Provides modern molecular biological insights into the mechanistic basis of adaptation, and takes the level of analysis beyond the cell to the membrane, enzyme and gene. Incorporates more varied material from a wide range of animal types, with less of a focus purely on terrestrial reptiles, birds and mammals and more on the spectacularly successful strategies of invertebrates. This is a core text for modern undergraduate courses in animal physiology, comparative physiology, environmental physiology and physiological ecology. It is also suitable for the physiological components of any animal biology course, and a key resource for degree courses in environmental biology.
Download or read book Ecological and Physiological Effects of Environmental Stressors Across Life stages in Amphibians written by Kacey Lynn Dananay and published by . This book was released on 2018 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the effects of environmental stressors includes identifying how stressors affect individual physiology and ecological communities. Considering carry-over effects, effects from one life-stage persisting into later life-stages, can further reduce the chances of under- or over-estimating the effects of environmental stressors. I investigated the effects of two environmental stressors on amphibian physiology across life-stages including direct and indirect effects. I first investigated road salt. Road salt, a de-icing agent used on highways, can spread up to 1km in wetlands during snowmelt. It may be particularly important for early breeding amphibians like wood frogs (Rana sylvatica). Road salt significantly increased larval frog growth and algal biomass which was likely due to an indirect effect of salt decreasing zooplankton abundance, an algal competitor of frogs. A second experiment found despite increased larval growth, exposure to road salt caused juvenile frogs to have higher mortality in low-density terrestrial environments. The second stressor I investigated was Artificial Light At Night (ALAN). ALAN reduced metamorphic duration of American toads (Anaxyrus americanus) and periphyton biomass but did not affect the colonization of toad predators. These results suggested the effects of ALAN are mediated through direct rather than indirect effects. Extending this experiment found juvenile growth was reduced by juvenile-stage exposure to ALAN. Increased juvenile activity, specifically the lack of suppressed nocturnal activity, likely reduced juvenile growth of individuals housed with ALAN. Furthermore, carry-over effects were also present; larval-stage ALAN marginally increased juvenile activity. In the final experiment, I added an additional stressor: predation. Predators reduced toad survival and mass, regardless of ALAN. This suggests ALAN did not increase predator consumption of toads. Neither predators nor ALAN affected corticosterone production in the tadpole or metamorph life-stages but larval-stage ALAN increased corticosterone production in juvenile toads. These experiments demonstrated environmental stressors can have direct and indirect effects. Furthermore, larval stage stressors can carry-over and affect later life-stages even if that stressor is no longer present. Future environmental stressor studies should investigate direct and indirect effects together and extend experiments beyond a single life-stage. As demonstrated here, failure to do so may under-estimated the effects of these environmental stressors.
Download or read book Physiology of the Amphibia written by Brian Lofts and published by Elsevier. This book was released on 2012-12-02 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physiology of the Amphibia, Volume III consists of 10 chapters beginning with a discussion on amphibian color changes and the various aspects of the molting cycle. Possessing a skin more suitable for life in the water, the amphibians need to prevent excessive water loss from their body to the environment; hence, an additional mechanism for reducing the hazards of desiccation in many anuran species is described. This book also tackles the physiology of amphibian cells in culture. Furthermore, the animals' nervous, visual, and auditory systems; their immunity; and metamorphosis are explained in this text. This reference will be useful to general biologists and to students with interests in animal physiology.

Download or read book The Role of Conservation Physiology and Environmental Change in Amphibian Declines written by Cory Benjamin Goff and published by . This book was released on 2019 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental change associated with anthropogenic alterations to habitat and the synergistic effects with climate change and disease can render habitats unsuitable and affect the physiological health of species. This can ultimately affect survival and fitness. Amphibians are one group of vertebrates especially vulnerable to changes in environmental quality. Using multiple measures of physiological health can aid in identifying populations at increased risk of declines. This dissertation focuses on research that examines the effects of environmental variables on the health of larval amphibians through field sampling, laboratory experiments, and outdoor mesocosms. The first chapter is an introduction to the main topics addressed in my research. The second chapter includes the results of field sampling to measure environmental variables at multiple spatial scales and their effects on three physiological health metrics of ornate chorus frog (Pseudacris ornata) tadpoles to identify potential correlates of population declines. The third chapter examines the effects of increased water temperatures on multiple physiological health metrics in a larval anuran, the Rio Grande leopard frog (Rana berlandieri) by manipulating water temperatures via tank heaters in the lab and from a lack of shade cover in outdoor mesocosms. Together, my research shows that lower environmental quality, such as increased water temperatures from climate change or habitat alteration, may result in chronic stress in larval amphibians, reducing physiological health and leading to declines. However, depending on the species and aquatic environment, some individuals may benefit from warmer water temperatures. My research suggests multiple health metrics are needed to understand the complex effects of environmental change on larval amphibian health and provides suggestions for the management of these species.

Available in PDF, EPUB and Kindle. Book excerpt: In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.
