This book was released on 2019 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predatory fish introduction can cause cascading changes within recipient freshwater ecosystems. Linkages to avian and terrestrial food webs may occur, but effects are thought to attenuate across ecosystem boundaries. Using data spanning more than four decades (1972?2017), we demonstrate that lake trout invasion of Yellowstone Lake added a novel, piscivorous trophic level resulting in a precipitous decline of prey fish, including Yellowstone cutthroat trout. Plankton assemblages within the lake were altered, and nutrient transport to tributary streams was reduced. Effects across the aquatic-terrestrial ecosystem boundary remained strong (log response ratio ? 1.07) as grizzly bears and black bears necessarily sought alternative foods. Nest density and success of ospreys greatly declined. Bald eagles shifted their diet to compensate for the cutthroat trout loss. These interactions across multiple trophic levels both within and outside of the invaded lake highlight the potential substantial influence of an introduced predatory fish on otherwise pristine ecosystems.

Book Synopsis Catching Yellowstone's Wild Trout by : Chris Hunt
Download or read book Catching Yellowstone's Wild Trout written by Chris Hunt and published by Arcadia Publishing. This book was released on 2019-06-17 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This history and guide to the fly-fishing waters of Yellowstone National Park is a loving homage to the region’s iconic wild trout. Yellowstone National Park is home to some of the most storied destinations in the history of fly fishing. Casting in the Firehole River is like going back in time to when bison roamed nearly every meadow in the West. Restored to their natal streams after near extinction, native Arctic grayling can once again be plucked from icy water at the foot of breathtaking waterfalls. Meanwhile, a daylong hike into true wild country rewards an angler with a chance to catch trophy native cutthroat trout on a lonely mountain lake. In Catching Yellowstone’s Wild Trout, local journalist and experienced angler Chris Hunt explores the rich history of these beloved and bountiful waters.
Book Synopsis Preserving Yellowstone's Natural Conditions by : James A. Pritchard
Download or read book Preserving Yellowstone's Natural Conditions written by James A. Pritchard and published by U of Nebraska Press. This book was released on 2022-10-05 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preserving Yellowstone's Natural Conditions describes in fascinating detail the historical origins and development of wildlife management in Yellowstone National Park, alongside shifting understandings of nature in science and culture. James A. Pritchard traces the idea of "natural conditions" through time, from the introduction of this concept by early ecologists in the 1930s. He tells several overlooked stories of Yellowstone wildlife, including a sensational scientific hunt for bears with bow and arrow, and the episode of the predator pelicans, which facilitated a fundamental shift toward protection of all wildlife in Yellowstone, and for the National Park Service as a whole. A prolonged debate regarding the elk herd on Yellowstone's northern range is addressed, along with the origins of the notion of natural regulation, and the reasons for ending direct reductions of elk. This story emphasizes how ecological science came to Yellowstone and to the National Park Service, subsequently developing over a period of decades. In the new afterword to this book Pritchard summarizes recent developments in wildlife science and management--such as the "ecology of fear" and trophic cascades--and discusses historical continuities in the role of the park as a wildlife refuge and the inestimable values of the park for wildlife conservation.
Download or read book The Wolf written by Ian Convery and published by Boydell & Brewer. This book was released on 2023-07-18 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: New insights into the changing human attitudes towards wild nature through the depiction of wolves in human culture and heritage. Few animals arouse such strong opinion as the wolf. It occupies a contested, ambiguous, yet central role in human culture and heritage. It appears as both an inspirational emblem of the wild and an embodiment of evil. Offering a mirror to different human attitudes, beliefs, and values, the wolf is, arguably, the species that plays the greatest role in shaping our views on what nature is or should be. North America and, more recently, Europe have witnessed a remarkable return of the grey wolf (Canis lupus, and its close relative the Eurasian wolf, Canis lupus lupus) to eco-systems. The essays collected here explore aspects of this recovery, and consider the history, literature and myth surrounding this iconic species. There are chapters on wolf taxonomy, including the coywolf, the red wolf, and the many faces of the dingo. We also meet the Tasmanian wolf and encounter Nazi Werewolves from Outer Space. The book explores the challenges of separating fact from fiction and superstition, and our willingness to co-exist with large carnivores in the twenty-first century. Biologists, historians, anthropologists, cultural theorists, conservationists and museologists will all find riches in the detail presented in this wolf collection.

Book Synopsis An Ape Ethic and the Question of Personhood by : Gregory F. Tague
Download or read book An Ape Ethic and the Question of Personhood written by Gregory F. Tague and published by Rowman & Littlefield. This book was released on 2020-03-05 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gregory F. Tague’s An Ape Ethic and the Question of Personhood argues that great apes are moral individuals because they engage in a land ethic as ecosystem engineers to generate ecologically sustainable biomes for themselves and other species. Tague shows that we need to recognize apes as eco-engineers in order to save them and their habitats, and that in so doing, we will ultimately save earth’s biosphere. The book draws on extensive empirical research from the ecology and behavior of great apes and synthesizes past and current understanding of the similarities in cognition, social behavior, and culture found in apes. Importantly, this book proposes that differences between humans and apes provide the foundation for the call to recognize forest personhood in the great apes. While all ape species are alike in terms of cognition, intelligence, and behaviors, there is a vital contrast: unlike humans, great apes are efficient ecological engineers. Therefore, simian forest sovereignty is critical to conservation efforts in controlling global warming, and apes should be granted dominion over their tropical forests. Weaving together philosophy, biology, socioecology, and elements from eco-psychology, this book provides a glimmer of hope for future acknowledgment of the inherent ethic that ape species embody in their eco-centered existence on this planet.

Book Synopsis Yellowstone National Park Fishing Regulations (Fish Stories) by : National Park Service
Download or read book Yellowstone National Park Fishing Regulations (Fish Stories) written by National Park Service and published by Createspace Independent Publishing Platform. This book was released on 2016-01-21 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angling for native fish is an important part of the park's cultural history. Fishing regulations in Yellowstone National Park are structured to strongly support native fish conservation goals. Cutthroat trout are the sole, native trout of the park and were the dominant fish species here prior to Euroamerican settlement. Cutthroat trout, Arctic grayling, mountain whitefish, and other native fishes are important to the ecology of Yellowstone. Introduced nonnative fish cause loss of native fish The number of waters where native fish are found and the abundance of native fish have been substantially reduced, mostly because of impacts by introduced nonnative fish, including brook, brown, lake, and rainbow trout. These nonnative species continue to contribute to the decline in the park's native fish population by competing for food and habitat, preying on native fish, and degrading the genetic integrity of native fish by mating with them and creating hybrids. Loss of native fish impacts park ecosystems Because cutthroat trout and Arctic grayling inhabit relatively shallow waters, many animals depend on them as a food source, especially during spring when the fish spawn in small lake inlets and tributary streams. In many cases, nonnative trout cannot serve as a substitute for cutthroat trout or Arctic grayling because they occupy different habitats. For example, nonnative lake trout live deep in Yellowstone Lake, do not spawn in streams, and are generally inaccessible to many of the park's native fish-eating animals such as bears, otters, and ospreys. A plan to preserve and restore native fish Yellowstone is making a substantial, on-the-ground effort to conserve native fish in several areas. These actions, which are currently focused in the Lamar and Grayling Creek drainages and Yellowstone Lake, are described in the park's native fish conservation plan. Goals of the plan are to reduce the risk of extinction, restore and maintain the ecological role, and create sustainable angling and viewing opportunities for native fish. Anglers assist with native species conservation The Native Trout Conservation Area (see pages 3 and 4) is a large region within the park where native cutthroat trout are actively being harmed by introduced nonnative fish. Angling is one way that the nonnative fish can be selectively removed from an area without damaging the native fishery. Within this area, anglers are strongly encouraged, and in some cases required, to harvest nonnative fish. Along with actions being taken by federal and state biologists and their partners, this harvest will help to save the native fish and the natural ecosystems they support.
Book Synopsis Freshwater Biodiversity by : David Dudgeon
Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Synopsis Climate Change in Wildlands by : Andrew J Hansen
Download or read book Climate Change in Wildlands written by Andrew J Hansen and published by Island Press. This book was released on 2016-06-07 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists have been warning for years that human activity is heating up the planet and climate change is under way. We are only just beginning to acknowledge the serious effects this will have on all life on Earth. The federal government is crafting broad-scale strategies to protect wildland ecosystems from the worst effects of climate change. One of the greatest challenges is to get the latest science into the hands of resource managers entrusted with vulnerable wildland ecosystems. This book examines climate and land-use changes in montane environments, assesses the vulnerability of species and ecosystems to these changes, and provides resource managers with collaborative management approaches to mitigate expected impacts. Climate Change in Wildlands proposes a new kind of collaboration between scientists and managers--a science-derived framework and common-sense approaches for keeping parks and protected areas healthy on a rapidly changing planet.

Book Synopsis Life-history Trait Shifts in Daphnia Pulicaria in Yellowstone Lake Following the Introduction of Lake Trout by : Tonya E. Anderson
Download or read book Life-history Trait Shifts in Daphnia Pulicaria in Yellowstone Lake Following the Introduction of Lake Trout written by Tonya E. Anderson and published by . This book was released on 2013 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent invasion (late 1980s) of piscivorous lake trout into Yellowstone Lake, WY, caused large changes in the aquatic community. For example, lake trout added a fourth trophic level to the food web thereby causing large declines in the population size of Yellowstone cutthroat trout, the primary food source of adult lake trout. Daphnia pulicaria is the second most abundant species of zooplankton in the lake, and the main prey item for native Yellowstone cutthroat trout. I compared D. pulicaria body size, clutch size, egg size, and probability of reproducing from archived Yellowstone National Park samples collected prior to lake trout invasion (1977-1981) to zooplankton samples collected post-invasion (2004 and 2008). Before lake trout were introduced, D. pulicaria matured at a smaller body size and carried larger clutches of smaller eggs. With these data, I cannot distinguish among several possible mechanisms for changes in life history traits, including rapid evolution due to reduced size-selective predation by cutthroat trout and adaptive or non-adaptive phenotypic plasticity. However, our results suggest that the introduction of lake trout and the subsequent changes that they caused in Yellowstone Lake have altered the life-history traits of D. pulicaria. While direct effects of invasions are often studied, indirect effects on lower trophic levels may have significant consequences for community composition and ecosystem function, but are rarely studied.
