If you’ve ever had a medical check-up, did you wonder why they put a cuff around your forearm, gave it a squeeze, and made you sit still and quiet? Or why they asked you to open your mouth so they could stick a thermometer under your tongue? Or put that cold stethoscope against your chest while you took deep breaths followed by sticking a clothespin thingamabob on your finger? What’s up with all the gizmos and gadgets and why all the bother?

What’s up is that all of these instruments measure the conditions of some of the most important, life-supporting functions, or vital signs, which keep your carcass from becoming, well, a carcass. The squeezy cuff is reading your blood pressure, which indicates how strongly your blood is pumping through your pipes. The thermometer measures your core body temperature, which affects many chemical reactions in your body that supply energy for your cells. With a stethoscope, the swooshing sound of air moving in and out of your lungs can be listened to. And the clothespin doohickey tracks the amount of oxygen being carried by your blood. Vital signs are critical indicators of your body’s overall health. By tracking them as you grow and mature, these measurements can be used as a guide or reference point for when your body isn’t feeling all that great.

Now what does your blood pressure have to do with US National Parks? While human vital signs are important in evaluating your body’s health, ecological vital signs are indicators for measuring ecosystem health. An ecosystem is a community of living organisms like frogs, trees, or bacteria, and nonliving materials such as water, dirt, and rocks that are located together and interact on some level. In a healthy ecosystem, all of the living and nonliving members exist in a state of natural balance in harmony with their environment. When something new enters the community, say a strange weed or insect, or something in the environment shifts, such as the air temperature becoming warmer, the health of the ecosystem can be threatened. Monitoring ecological vital signs gives scientists a reference point or baseline of the natural condition and alerts them when there is a change. While a healthy ecosystem can continue to support all its members and adapt to change, sometimes changes are too great and members of the ecosystem become stressed and have a hard time keeping up.

Although US National Parks are some of the most protected areas on the planet, the ecological health of many of these carefully safeguarded lands is increasingly uncertain due to our rapidly changing global environment. Here we present a collection of articles about how we study and understand the health of park ecosystems by measuring and tracking the condition of ecological vital signs. This scientific data helps park managers protect the valued resources of our parks and lessen harmful impacts when change is inevitable.

Download or read book Yellowstone s Wildlife in Transition written by P. J. White and published by Harvard University Press. This book was released on 2013-04-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's first national park, Yellowstone is a symbol of nature's enduring majesty and the paradigm of protected areas across the globe. But Yellowstone is constantly changing. How we understand and respond to events that are putting species under stress, say the authors of Yellowstone's Wildlife in Transition, will determine the future of ecosystems that were millions of years in the making. With a foreword by the renowned naturalist E. O. Wilson, this is the most comprehensive survey of research on North America's flagship national park available today. Marshaling the expertise of over thirty contributors, Yellowstone's Wildlife in Transition examines the diverse changes to the park's ecology in recent decades. Since its creation in the 1870s, the priorities governing Yellowstone have evolved, from intensive management designed to protect and propagate depleted large-bodied mammals to an approach focused on restoration and preservation of ecological processes. Recognizing the importance of natural occurrences such as fires and predation, this more ecologically informed oversight has achieved notable successes, including the recovery of threatened native species of wolves, bald eagles, and grizzly bears. Nevertheless, these experts detect worrying signs of a system under strain. They identify three overriding stressors: invasive species, private-sector development of unprotected lands, and a warming climate. Their concluding recommendations will shape the twenty-first-century discussion over how to confront these challenges, not only in American parks but for conservation areas worldwide. Highly readable and fully illustrated, Yellowstone's Wildlife in Transition will be welcomed by ecologists and nature enthusiasts alike.

Download or read book Yellowstone s Destabilized Ecosystem written by Frederic H. Wagner and published by Oxford University Press. This book was released on 2006-05-25 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wagner, one of our most distinguished wildlife biologists, is a strong critic of ecological practices in the national parks. This book provides an assessment of the ecological history of Yellowstone's northern range, since before the park existed, showing the impact of US Park Service policies on the health of the areas they oversee. He demonstrates that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area. This is a major contribution to reconstructing the ecology of this region over the course of the past 500 years. It is also a critique of US Park Service management policies and their stewardship of the nation's most cherished natural areas. Wagner's book will generate substantial attention and debate both in the scientific and policy/management communities.

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.

Available in PDF, EPUB and Kindle. Book excerpt: “A huge, beautiful compendium of 600 frogs from around the world, from the famed poison-arrow variety on up to the intriguingly named plaintive rain frog.” —Wired With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world. “If you are a serious (and I mean serious) fan of the frog, you are in for a real treat.” —Boing Boing

Download or read book Landscape scale Conservation Planning written by Stephen C. Trombulak and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hugh P. Possingham Landscape-scale conservation planning is coming of age. In the last couple of decades, conservation practitioners, working at all levels of governance and all spatial scales, have embraced the CARE principles of conservation planning – Comprehensiveness, Adequacy, Representativeness, and Efficiency. Hundreds of papers have been written on this theme, and several different kinds of software program have been developed and used around the world, making conservation planning based on these principles global in its reach and influence. Does this mean that all the science of conservation planning is over – that the discovery phase has been replaced by an engineering phase as we move from defining the rules to implementing them in the landscape? This book and the continuing growth in the literature suggest that the answer to this question is most definitely ‘no. ’ All of applied conservation can be wrapped up into a single sentence: what should be done (the action), in what place, at what time, using what mechanism, and for what outcome (the objective). It all seems pretty simple – what, where, when, how and why. However stating a problem does not mean it is easy to solve.

Download or read book Wildlife Management and Landscapes written by William F. Porter and published by JHU Press. This book was released on 2021-05-11 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife management specialists and landscape ecologists offer a new perspective on the important intersection of these fields in the twenty-first century. It's been clear for decades that landscape-level patterns and processes, along with the tenets and tools of landscape ecology, are vitally important in understanding wildlife-habitat relationships and sustaining wildlife populations. Today, significant shifts in the spatial scale of extractive, agricultural, ranching, and urban land uses are upon us, making it more important than ever before to connect wildlife management and landscape ecology. Landscape ecologists must understand the constraints that wildlife managers face and be able to use that knowledge to translate their work into more practical applications. Wildlife managers, for their part, can benefit greatly from becoming comfortable with the vocabulary, conceptual processes, and perspectives of landscape ecologists. In Wildlife Management and Landscapes, the foremost landscape ecology experts and wildlife management specialists come together to discuss the emerging role of landscape concepts in habitat management. Their contributions • make the case that a landscape perspective is necessary to address management questions • translate concepts in landscape ecology to wildlife management • explain why studying some important habitat-wildlife relationships is still inherently difficult • explore the dynamic and heterogeneous structure of natural systems • reveal why factors such as soil, hydrology, fire, grazing, and timber harvest lead to uncertainty in management decisions • explain matching scale between population processes and management • discuss limitations to management across jurisdictional boundaries and balancing objectives of private landowners and management agencies • offer practical ideas for improving communication between professionals • outline the impediments that limit a full union of landscape ecology and wildlife management Using concrete examples of modern conservation challenges that range from oil and gas development to agriculture and urbanization, the volume posits that shifts in conservation funding from a hunter constituent base to other sources will bring a dramatic change in the way we manage wildlife. Explicating the foundational similarity of wildlife management and landscape ecology, Wildlife and Landscapes builds crucial bridges between theoretical and practical applications.

Download or read book Status of Conservation and Decline of Amphibians written by Harold Heatwole and published by CSIRO PUBLISHING. This book was released on 2018-06-01 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibians are among the most threatened groups of animals on earth. In part due to their highly permeable skin, amphibians are highly sensitive to environmental changes and pollution and provide an early-warning system of deteriorating environmental conditions. The more we learn about the impact of environmental changes on amphibians, the better we as humans will be able to arrest their demise, and our own. Status of Conservation and Decline of Amphibians brings together the current knowledge on the status of the unique frogs of Australia, New Zealand, and the Pacific. Although geographically proximate, each region presents unique challenges and opportunities in amphibian research and conservation. This book contributes to an understanding of the current conservation status of the amphibians of each region, aims to stimulate research into halting amphibian declines, and provides a better foundation for making conservation decisions. It is an invaluable reference for environmental and governmental agencies, researchers, policy-makers involved with biodiversity conservation, and the interested public.
