Available in PDF, EPUB and Kindle. Book excerpt: Populations of brook trout in streams of Shenandoah National Park were reduced drastically early in the past decade by a succession of unusually severe droughts and floods. The drying of stream beds, predation, and scouring were principal factors in the loss of fish. The park was closed to fishing in 1954 and 1955 to protect survivors. The small numbers of survivors quickly repopulated the streams after drought conditions abated. The stocking of hatchery-reared fingerling trout in selected waters failed to augment the recovery of populations. Survival and growth of young, wild trout were especially good. Their redistribution through miles of previously dry streams was rapid. The park was opened again to fishing in 1956 under regulations which restrict the take but afford an increase in sporting opportunity. Two streams were placed under fishing-for-fun-only regulations in 1961. The welfare of the trout populations is dependent mostly on the weather cycle. Fish may be abundant in wet years but very scarce in dry ones. Thus, the stream must be managed as marginal for trout.

Download or read book Landscape Ecology in Theory and Practice written by Monica G. Turner and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

Download or read book Exploring Earth Science written by Julia Johnson and published by McGraw-Hill Education. This book was released on 2015-02-06 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring Earth Science by Reynolds/Johnson is an innovative textbook intended for an introductory college geology course, such as Earth Science. This ground-breaking, visually spectacular book was designed from cognitive and educational research on how students think, learn, and study. Nearly all information in the book is built around 2,600 photographs and stunning illustrations, rather than being in long blocks of text that are not articulated with figures. These annotated illustrations help students visualize geologic processes and concepts, and are suited to the way most instructors already teach. To alleviate cognitive load and help students focus on one important geologic process or concept at a time, the book consists entirely of two-page spreads organized into 20 chapters. Each two-page spread is a self-contained block of information about a specific topic, emphasizing geologic concepts, processes, features, and approaches. These spreads help students learn and organize geologic knowledge in a new and exciting way. Inquiry is embedded throughout the book, modeling how scientists investigate problems. The title of each two-page spread and topic heading is a question intended to get readers to think about the topic and become interested and motivated to explore the two-page spread for answers. Each chapter is a learning cycle, which begins with a visually engaging two-page spread about a compelling geologic issue. Each chapter ends with an Investigation that challenges students with a problem associated with a virtual place. The world-class media, spectacular presentations, and assessments are all tightly articulated with the textbook. This book is designed to encourage students to observe, interpret, think critically, and engage in authentic inquiry, and is highly acclaimed by reviewers, instructors, and students.
Download or read book Occoneechee The Maid of the Mystic Lake written by Robert Frank Jarrett and published by Library of Alexandria. This book was released on 2020-09-28 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This history has been gleaned from the works of Ethnology by James Mooney and from word of mouth, as related to the author during the past thirty years. In the beginning of historical events, we hear of man in his paradisaical home, located somewhere within the boundaries known as ancient Egypt or Chaldea. His home was far away and his former history shrouded in the darkness of countless centuries of the past, and when we contemplate the remoteness of his ancestry, we become lost in the midst of our own research. When historical light began to flash from the Orient, we find man emerging with some degree of civilization from a barbaric state into the advanced degrees of civilized and enlightened tribes. When the maritime navigator, full of visions and dreams, dared to sail for those hitherto undiscovered shores, now known as America, there lived within the realm a wandering, happy, yet untutored, race of men whom we afterwards called Indians, who dwelt in great numbers along the whole distance from Penobscot Bay south to the everglades of Florida.
Download or read book Hurricanes written by Roger A. Pielke, Sr. and published by . This book was released on 1997 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Losses to hurricanes in the 1990s total more than those incurred in the 1970s and 1980s combined, even after adjusting for inflation. This has led many to mistakenly conclude that severe hurricanes are becoming more frequent. In fact, according to recent research, the past few decades have seen a decrease in the frequency of severe storms and 1991 to 1994 was the quietest in at least 50 years. It does mean, however, that the world today is more vulnerable to hurricane impacts than it has ever been, which represents a serious policy problem. This book defines and assesses the hurricane problem, focusing primarily on the United States, in order to lay a foundation for action. The concept of vulnerability is used to integrate the societal and physical aspects of hurricane impacts. The book is unique in that it seeks to address both the scientific and societal aspects of hurricanes. While it focuses on the United States, it is intended to illustrate weather related impacts assessment that could be applied in other areas, and for phenomena other than hurricanes. More broadly, this book seeks to illustrate the beneficial uses (as well as limitations) of hurricane science to society. Explicit consideration of the relationship between science and society is much needed in an era when scientific research is under public and political pressure to demonstrate a better connection with societal needs.
