Download or read book Aquatic Dicotyledons of North America written by Donald H. Les and published by CRC Press. This book was released on 2017-09-01 with total page 3174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic Dicotyledons of North America: Ecology, Life History, and Systematics brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic plants. Most books on aquatic plants have a taxonomic focus and are intended primarily for identification. Instead, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference materials. Included dicotyledon species are those having an obligate (OBL) wetland status, a designation used in the USACE National Wetland Plant List. Recent phylogenetic analyses are incorporated and rationale is provided for interpreting this information with respect to species relationships. This diverse assemblage of information will be useful to a wide range of interests including academic researchers, wildlife managers, students, and virtually anyone interested in the natural history of aquatic and wetland plants. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. This book is an essential resource for assisting with wetland delineation.
Download or read book Wildlife Ecology and Management in Mexico written by Raul Valdez and published by Texas A&M University Press. This book was released on 2019-01-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico’s wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico’s wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.

Download or read book Prairie Ghost written by Richard E McCabe and published by University Press of Colorado. This book was released on 2011-05-18 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this lavishly illustrated volume, Richard E. McCabe, Bart W. O'Gara and Henry M. Reeves explore the fascinating relationship of pronghorn with people in early America, from prehistoric evidence through the Battle of Little Bighorn in 1876. The only one of fourteen pronghorn-like genera to survive the great extinction brought on by human migration into North America, the pronghorn has a long and unique history of interaction with humans on the continent, a history that until now has largely remained unwritten. With nearly 150 black-and-white photographs, 16 pages of color illustrations, plus original artwork by Daniel P. Metz, Prairie Ghost: Pronghorn and Human Interaction in Early America tells the intriguing story of humans and these elusive big game mammals in an informative and entertaining fashion that will appeal to historians, biologists, sportsmen and the general reader alike.
Download or read book Preserving the Desert written by Lary M. Dilsaver and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: National parks are different from other federal lands in the United States. Beginning in 1872 with the establishment of Yellowstone, they were largely set aside to preserve for future generations the most spectacular and inspirational features of the country, seeking the best representative examples of major ecosystems such as Yosemite, geologic forms such as the Grand Canyon, archaeological sites such as Mesa Verde, and scenes of human events such as Gettysburg. But one type of habitat--the desert--fell short of that goal in American eyes until travel writers and the Automobile Age began to change that perception. As the Park Service began to explore the better-known Mojave and Colorado deserts of southern California during the 1920s for a possible desert park, many agency leaders still carried the same negative image of arid lands shared by many Americans--that they are hostile and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, with the area later expanded in 1994 when it became Joshua Tree National Park. Since 1936, the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that any desert is suitable for anything other than their consumptive activities. To their dismay, Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
Download or read book Papillomaviruses and Human Disease written by Kari J. Syrjänen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, papillomaviruses in general and human papillo maviruses in particular have been recognized as possible agents of important diseases, including some forms of human cancer. The purpose of this book is to present a concise panorama of the pre sent status of knowledge of this topic. This knowledge is as impor tant to molecular biologists and virologists as it is to clinicians and pathologists. To bridge the gap among these diverse groups of investigators, we conceived of a book covering a broad spectrum of the basic scientific, clinical, and pathological aspects of diseases associated with papillomaviruses. Although the principal thrust of this book is directed at human papillomaviruses, fundamental knowledge of animal viruses is essential to the current understand ing of the molecular mechanisms of cell transformation. For this reason, a chapter on animal viruses has also been included. Some of the experimental work having to do with the elucidation of transformation and other aspects of interaction between the virus and the cell cannot be based on human papillomaviruses because of a lack of suitable experimental models. Hence, some of the chapters dealing with fundamental aspects of viral molecular biol ogy are based on animal models. We were very fortunate in having persuaded a number of distin guished colleagues to contribute to this work.

Download or read book History Of Utah s American Indians written by Forrest Cuch and published by Utah State Division of Indian Affairs. This book was released on 2003-10-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a joint project of the Utah Division of Indian Affairs and the Utah State Historical Society. It is distributed to the book trade by Utah State University Press. The valleys, mountains, and deserts of Utah have been home to native peoples for thousands of years. Like peoples around the word, Utah's native inhabitants organized themselves in family units, groups, bands, clans, and tribes. Today, six Indian tribes in Utah are recognized as official entities. They include the Northwestern Shoshone, the Goshutes, the Paiutes, the Utes, the White Mesa or Southern Utes, and the Navajos (Dineh). Each tribe has its own government. Tribe members are citizens of Utah and the United States; however, lines of distinction both within the tribes and with the greater society at large have not always been clear. Migration, interaction, war, trade, intermarriage, common threats, and challenges have made relationships and affiliations more fluid than might be expected. In this volume, the editor and authors endeavor to write the history of Utah's first residents from an Indian perspective. An introductory chapter provides an overview of Utah's American Indians and a concluding chapter summarizes the issues and concerns of contemporary Indians and their leaders. Chapters on each of the six tribes look at origin stories, religion, politics, education, folkways, family life, social activities, economic issues, and important events. They provide an introduction to the rich heritage of Utah's native peoples. This book includes chapters by David Begay, Dennis Defa, Clifford Duncan, Ronald Holt, Nancy Maryboy, Robert McPherson, Mae Parry, Gary Tom, and Mary Jane Yazzie. Forrest Cuch was born and raised on the Uintah and Ouray Ute Indian Reservation in northeastern Utah. He graduated from Westminster College in 1973 with a bachelor of arts degree in behavioral sciences. He served as education director for the Ute Indian Tribe from 1973 to 1988. From 1988 to 1994 he was employed by the Wampanoag Tribe in Gay Head, Massachusetts, first as a planner and then as tribal administrator. Since October 1997 he has been director of the Utah Division of Indian Affairs.
