Download or read book Predicting Breeding Habitat for Amphibians: a Spatiotemporal Analysis Across Yellowstone National Park written by Paul E. Bartelt and published by . This book was released on 2011 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to predict amphibian breeding across landscapes is important for informing land management decisions and helping biologists better understand and remediate factors contributing to declines in amphibian populations. We built geospatial models of likely breeding habitats for each of four amphibian species that breed in Yellowstone National Park (YNP). We used field data collected in 2000?2002 from 497 sites among 16 basins and predictor variables from geospatial models produced from remotely sensed data (e.g., digital elevation model, complex topographic index, landform data, wetland probability, and vegetative cover). Except for 31 sites in one basin that were surveyed in both 2000 and 2002, all sites were surveyed once. We used polytomous regression to build statistical models for each species of amphibian from (1) field survey site data only, (2) field data combined with data from geospatial models, and (3) data from geospatial models only. Based on measures of receiver operating characteristic (ROC) scores, models of the second type best explained likely breeding habitat because they contained the most information (ROC values ranged from 0.70 to 0.88). However, models of the third type could be applied to the entire YNP landscape and produced maps that could be verified with reserve field data. Accuracy rates for models built for single years were highly variable, ranging from 0.30 to 0.78. Accuracy rates for models built with data combined from multiple years were higher and less variable, ranging from 0.60 to 0.80. Combining results from the geospatial multiyear models yielded maps of ?core? breeding areas (areas with high probability values for all three years) surrounded by areas that scored high for only one or two years, providing an estimate of variability among years. Such information can highlight landscape options for amphibian conservation. For example, our models identify alternative areas that could be protected for each species, including 6828?10 764 ha for tiger salamanders, 971?3017 ha for western toads, 4732?16 696 ha for boreal chorus frogs, and 4940?19 690 ha for Columbia spotted frogs.

Available in PDF, EPUB and Kindle. Book excerpt: Monitoring of natural resources is crucial to ecosystem conservation, and yet it can pose many challenges. Annual surveys for amphibian breeding occupancy were conducted in Yellowstone and Grand Teton National Parks over a 4-year period (2006?2009) at two scales: catchments (portions of watersheds) and individual wetland sites. Catchments were selected in a stratified random sample with habitat quality and ease of access serving as strata. All known wetland sites with suitable habitat were surveyed within selected catchments. Changes in breeding occurrence of tiger salamanders, boreal chorus frogs, and Columbia-spotted frogs were assessed using multi-season occupancy estimation. Numerous a priori models were considered within an information theoretic framework including those with catchment and site-level covariates. Habitat quality was the most important predictor of occupancy. Boreal chorus frogs demonstrated the greatest increase in breeding occupancy at the catchment level. Larger changes for all 3 species were detected at the finer site-level scale. Connectivity of sites explained occupancy rates more than other covariates, and may improve understanding of the dynamic processes occurring among wetlands within this ecosystem. Our results suggest monitoring occupancy at two spatial scales within large study areas is feasible and informative.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an authoritative work on the ecology of some of America’s most iconic large mammals in a natural environment - and of the interplay between climate, landscape, and animals in the interior of the world’s first and most famous national park.Central Yellowstone includes the range of one of the largest migratory populations of bison in North America as well as a unique elk herd that remains in the park year round. These populations live in a varied landscape with seasonal and often extreme patterns of climate and food abundance. The reintroduction of wolves into the park a decade ago resulted in scientific and public controversy about the effect of large predators on their prey, a debate closely examined in the book. Introductory chapters describe the geography, geology and vegetation of the ecosystem. The elk and bison are then introduced and their population ecology described both pre- and post– wolf introduction, enabling valuable insights into the demographic and behavioral consequences for their ungulate prey. Subsequent chapters describe the wildlife-human interactions and show how scientific research can inform the debate and policy issues surrounding winter recreation in Yellowstone. The book closes with a discussion of how this ecological knowledge can be used to educate the public, both about Yellowstone itself and about science, ecology and the environment in general. Yellowstone National Park exemplifies some of the currently most hotly debated and high-profile ecological, wildlife management, and environmental policy issues and this book will have broad appeal not only to academic ecologists, but also to natural resource students, managers, biologists, policy makers, administrators and the general public. Unrivalled descriptions of ecological processes in a world famous ecosystem, based on information from 16 years of painstaking field work and collaborations among 66 scientists and technical experts and 15 graduate studies Detailed studies of two charismatic North American herbivore species – elk and bison Description of the restoration of wolves into central Yellowstone and their ecological interactions with their elk and bison prey Illustrated with numerous evocative colour photographs and stunning maps

This book was released on 2013-08-28 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about amphibians have escalated since population declines became apparent in diverse areas around the world in the 1980s (Collins and Storfer 2003). Systematic examinations have revealed that in some regions, including North America, rapid declines probably began around the middle of the 20th century, with the rate of decline increasing in the 1990s (Houlahan et al. 2000; Alford et al. 2001). Worldwide, 32% of amphibian species are now threatened with extinction, while 43% exhibit some form of population decrease (Stuart et al. 2004). Amidst the rapid and general decline in global biodiversity, amphibian population extinctions and declines are particularly alarming because they are occurring not only where habitat has been lost, but also in natural, protected areas.

Download or read book Remote Sensing of Wetlands in Yellowstone National Park written by Christopher Kevin Wright and published by . This book was released on 2004 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the Amphibian Research and Monitoring Initiative, satellite remote sensing was used to identify potential wetland amphibian habitat in Yellowstone National Park. Landsat Thematic Mapper imagery was combined with ancillary predictors of wetland occurrence including habitat type, cover type, landform type, bedrock geology, soil attributes, terrain measures, and climate data. Classification trees were used to predict the likelihood of palustrine wetland occurrence across the Yellowstone landscape. Wetland maps generated by this study are intended to address shortcomings of the National Wetland Inventory in Yellowstone; namely, errors-of-omission and the temporally invariant nature of the inventory. Relative importance of Thematic Mapper imagery, image texture information, terrain measures, and thematic spatial data were assessed by comparing the accuracy of classification trees trained with different subsets of predictors. In general, classification trees using all available predictors exhibited the greatest accuracy. Classification tree structure was similar in models generated with satellite imagery from different years. Also, similar accuracy rates were found across years. The results indicate that the method could be applied to annual wetland monitoring. Average producer's accuracy for the palustrine wetland class was approximately 0.92. Five palustrine wetland classes were discriminated with an average overall accuracy of approximately 0.83. A wetland map derived from a 1 August, 2003 Thematic Mapper image was field-verified in late-summer and early-autumn of 2003. The classification tree methodology appears to be sensitive to within-season wetland condition and yearly wetland variability. Satellite remote sensing located wetlands not mapped by the National Wetland Inventory and also identified upland sites erroneously classified as wetland. Methods developed by this study are general enough to be applied in other physiographic settings and should prove to be useful to amphibian conservation efforts over large geographic extents.

This book was released on 2002-02-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.

Book excerpt: It is widely assumed that Yellowstone National Park is a year-round sanctuary for wildlife'a landscape that protects animals within park boundaries from human impacts. But the Park alone can neither contain nor sustain many of the wide-ranging species that people generally associate with it. Populations of large mammals, raptors, waterfowl, and many other species require space far beyond park boundaries during at least part of each year, to secure the resources necessary to survive and reproduce. To these creatures, the boundaries of our parks, forests, and ranches are invisible.In this publication and the museum exhibition it accompanies, noted authorities in several fields explore the invisible boundaries of the Greater Yellowstone Ecosystem from diverse perspectives. Eminent conservation biologist Thomas Lovejoy places Greater Yellowstone in a global context, identifying the implications of animal movements for ecosystem conservation in our fragmented world. Ecologist and wildlife biologist Charles Preston reviews the genesis of the Greater Yellowstone Ecosystem concept and how it holds up to our current knowledge of wildlife movements and changing environments inside and outside Yellowstone National Park. Ecologist Arthur Middleton explains why elk and their spectacular annual migrations through the rugged country in and around Yellowstone are ideal vehicles to help us understand the challenges of cross-boundary movements. Wildlife photojournalist Joe Riis takes us along on the journeys of elk and other wildlife through Greater Yellowstone's magnificent backcountry, sharing his ground-breaking photography along with insights from nearly a decade of field work documenting these monumental journeys. Further extending the dialogue, artist James Prosek explores elk and other animal migrations through original artwork, freeing us from scientific and documentary boundaries to consider Yellowstone, conservation, and nature's fluidity from a different plane of human experience. Art historian Karen McWhorter ties everything together with observations and historical perspectives on collaborations among scientists, artists, and photographers toward increasing appreciation and understanding of the complex natural phenomenon of Yellowstone's great animal migrations.

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.
