This book was released on 2021 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenically-induced salinization of freshwater systems due to the application of road de-icing salts and hydrocarbon mining has been identified as a significant environmental stressor for amphibians across the United States. While the effects of salinity during amphibian embryonic and larval stages are fairly well-understood, less is known on whether these effects can carry over to affect post-metamorphic traits. Moreover, it remains unclear if salinity-induced carry-over effects are adaptive or maladaptive for amphibian survival, or if salinity can interact with other environmental conditions, like temperature, to influence amphibian development. To fill in these gaps, we tested the hypothesis that if wood frogs that develop in saline ponds exhibit adaptive plasticity in their osmoregulatory abilities, then individuals raised in elevated salinity environments as larvae would feature greater tolerance to similarly saline post-metamorphic environments (i.e., the match hypothesis). In addition, we also hypothesized that exposure to elevated salinity and temperature during larval development would have measurable impacts on juvenile behaviors. Our results provided no evidence for the match hypothesis, as juveniles reared in high salinities did not survive or grow better in high-salinity soils compared with those in low-salinity soils. However, we do show that juveniles that experienced elevated salinity as larvae tended to increase weight (but not SVL) regardless of post-metamorphic environment, suggesting that there may be differences in food intake or osmoregulation in these animals. We also showed that the interaction between salinity and temperature experienced during the larval stage affects wood frog explorative capacity without necessarily impacting exploitative behavior, providing evidence for behavioral carry-over effects. Taken together, these findings contribute to a growing body of work to show that the larval environment can affect the expression of physiological and behavioral traits after metamorphosis, but how these traits relate to population recruitment still needs to be investigated. Findings from this study also suggests that salinization of both freshwater and woodland soils adjacent to roads has adverse effects on wood frogs in both the aquatic and terrestrial parts of their life cycle.
Download or read book Conservation Physiology written by Christine L. Madliger and published by Oxford University Press. This book was released on 2020-11-30 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation physiology is a rapidly expanding, multidisciplinary field that utilizes physiological knowledge and tools to understand and solve conservation challenges. This novel text provides the first consolidated overview of its scope, purpose, and applications, with a focus on wildlife. It outlines the major avenues and advances by which conservation physiology is contributing to the monitoring, management, and restoration of wild animal populations. This book also defines opportunities for further growth in the field and identifies critical areas for future investigation. By using a series of global case studies, contributors illustrate how approaches from the conservation physiology toolbox can tackle a diverse range of conservation issues including the monitoring of environmental stress, predicting the impact of climate change, understanding disease dynamics, improving captive breeding, and reducing human-wildlife conflict. Moreover, by acting as practical road maps across a diversity of sub-disciplines, these case studies serve to increase the accessibility of this discipline to new researchers. The diversity of taxa, biological scales, and ecosystems highlighted illustrate the far-reaching nature of the discipline and allow readers to gain an appreciation for the purpose, value, applicability, and status of the field of conservation physiology. Conservation Physiology is an accessible supplementary textbook suitable for graduate students, researchers, and practitioners in the fields of conservation science, eco-physiology, evolutionary and comparative physiology, natural resources management, ecosystem health, veterinary medicine, animal physiology, and ecology.

Download or read book Applications of Conservation Physiology to Wildlife Fitness and Population Health written by Terri J. Maness and published by Frontiers Media SA. This book was released on with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the great challenges in ecophysiology is linking physiological measures in wild animal populations with changes in individual fitness. Physiological variables that indicate nutritional state, stress, disease, or injury are used extensively in veterinary practice and captive settings to assess the health and likelihood of reproductive success of many animals. The development and refinement of sampling methods that limit disturbance of animals, coupled with advancements in analytical methods have allowed researchers to begin to examine the relevance of these physiological parameters in wild animals for predicting population trends and response to environmental perturbations. However, despite extensive research in this field, consistent correlations between fitness and/or population health and physiological measures remain rare.
Download or read book Ranaviruses written by Matthew J. Gray and published by Springer. This book was released on 2015-05-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on ranaviruses. Ranaviruses are double-stranded DNA viruses that cause hemorrhagic disease in amphibians, reptiles, and fish. They have caused mass die-offs of ectothermic vertebrates in wild and captive populations around the globe. There is evidence that this pathogen is emerging and responsible for population declines in certain locations. Considering that amphibians and freshwater turtles are suitable hosts and the most imperiled vertebrate taxa in the world, ranaviruses can have significant impacts on biodiversity and ecosystem function. Additionally, many fish that are raised in aquaculture facilities and traded internationally are suitable hosts; thus, the potential economic impact of ranaviruses is significant. Ranaviruses also serve as a model for replication and gene function of large double-stranded DNA viruses. There is an urgent need to assemble the contemporary information on ranaviruses and provide guidance on how to assess their threats in populations. Through the Global Ranavirus Consortium, 24 experts from six countries were organize to write this volume, the first book on ranaviruses. The book begins with a discussion on the global extent of ranaviruses, case histories of infection and disease in ectothermic vertebrates, and current phylogeny. Basic principles of ranavirus ecology and evolution are covered next, with a focus on host-pathogen interactions and how the virus emerges in its environment. There are two chapters that will discuss the molecular biology of ranaviruses, host response to infection, and the genes responsible for immune system evasion. One chapter establishes standards for testing for infection and diagnosing ranaviral disease. The book ends by providing guidance on how to design ranavirus surveillance studies and analyze data to determine risk, and discussing the role of the Global Ranavirus Consortium in organizing research and outreach activities.

Download or read book Advances in Comparative Immunology written by Edwin L. Cooper and published by Springer. This book was released on 2018-08-07 with total page 1063 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunologists, perhaps understandably, most often concentrate on the human immune system, an anthropocentric focus that has resulted in a dearth of information about the immune function of all other species within the animal kingdom. However, knowledge of animal immune function could help not only to better understand human immunology, but perhaps more importantly, it could help to treat and avoid the blights that affect animals, which consequently affect humans. Take for example the mass death of honeybees in recent years – their demise, resulting in much less pollination, poses a serious threat to numerous crops, and thus the food supply. There is a similar disappearance of frogs internationally, signaling ecological problems, among them fungal infections. This book aims to fill this void by describing and discussing what is known about non-human immunology. It covers various major animal phyla, its chapters organized in a progression from the simplest unicellular organisms to the most complex vertebrates, mammals. Chapters are written by experts, covering the latest findings and new research being conducted about each phylum. Edwin L. Cooper is a Distinguished Professor in the Laboratory of Comparative Immunology, Department of Neurobiology at UCLA’s David Geffen School of Medicine.
Download or read book The Longleaf Pine Ecosystem written by Shibu Jose and published by Springer Science & Business Media. This book was released on 2006-05-18 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The longleaf pine ecosystem, once one of the most extensive ecosystems in North America, is now among the most threatened. Over the past few centuries, land clearing, logging, fire suppression, and the encroachment of more aggressive plants have led to an overwhelming decrease in the ecosystem’s size, to approximately 2.2% of its original coverage. Despite this devastation, the range of the longleaf still extends from Virginia to Texas. Through the combined efforts of organizations such as the USDA Forest Service, the Longleaf Alliance, and the Nature Conservancy, extensive programs to conserve, restore, and manage the ecosystem are currently underway. The longleaf pine ecosystem is valued not only for its aesthetic appeal, but also for its outstanding biodiversity, habitat value, and for the quality of the longleaf pine lumber. It has a natural resistance to fire and insects, and supports more than thirty threatened or endangered plant and animal species, including the red-cockaded woodpecker and the gopher tortoise. The Longleaf Pine Ecosystem unites a wealth of current information on the ecology, silviculture, and restoration of this ecosystem. The book also includes a discussion of the significant historical, social, and political aspects of ecosystem management, making it a valuable resource for students, land managers, ecologists, private landowners, government agencies, consultants, and the forest products industry. About the Editors: Dr. Shibu Jose is Associate Professor of Forest Ecology and Dr. Eric J. Jokela is Professor of Silviculture at the School of Forest Resources and Conservation at the University of Florida in Gainesville. Dr. Deborah L. Miller is Associate Professor of Wildlife Ecology in the Department of Wildlife Ecology and Conservation at the University of Florida in Milton.
