Download or read book Saguaro National Monument Arizona written by Napier Shelton and published by anboco. This book was released on 2016-09-28 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a simple account of the natural history of Saguaro National Monument. It is intended to help you understand the relationships between land, climate, plants, wild animals, and man in the environment of a hot desert. While it includes brief profiles of many representative species, it is not intended to serve as a guide to the monument. It does indicate where the several distinctive natural communities exist, and when and where to look for certain plants and animals. For identification purposes, you will need field guides. The present edition is my revision of the 1957 book by Natt Dodge, then naturalist for the Southwest Region of the National Park Service. The first five and the last two chapters are essentially new; the central chapters on plants and animals remain largely as written in the first edition. The authors wish to thank former and present members of the monument staff for their help and companionship, in both field and office. We are particularly grateful to Chief Naturalist Harold T. Coss, Jr., who devoted much time and effort to obtaining many of the photographs and, with Park Biologist Warren F. Steenbergh, gave the manuscript a thorough scrutiny. The cooperation and hospitality of Superintendent Harold R. Jones have created the best possible climate for work on the revised edition. National Park Service geologist Robert H. Rose contributed in very great measure to the geological content. Finally, our thanks go to the many students of desert life on whose knowledge this book has been built, and to monument visitors who ask questions—for their concern gives hope for better relations between man and nature. —N.S.

Download or read book Physiological Ecology of North American Plant Communities written by Brain F. Chabot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

Download or read book Estimating Numbers of Terrestrial Birds written by C. John Ralph and published by . This book was released on 2003-06 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published in 1981 as a publication of the Cooper Ornithological Society and was based on the proceedings of a meeting of biologists and statisticians in Asilomar who gathered to examine the methods and assumptions used in estimating bird numbers. Counting birds has a long tradition. It is the currency of many ornithological studies. Bird counts have been seminal in our knowledge of bird migration, competition, ecology, population dynamics, environmental adaptation, impact of human alterations and island biogeography. Interest in estimating bird numbers remains high today but is often plagued by unasked or unanswered questions regarding sampling methods and treatment of the results. This book recorded the outcome of a meeting held to address these and other questions. It led to better understanding of what can and cannot be done with datasets. This volume remains a primary source of information on censusing of birds and other animals, and is frequently quoted in the primary literature of today. Since this volume went out of print some six years ago, demand has markedly increased for copies which are essentially unavailable, attesting to its currency today. C. John Ralph, received his Bachelors from the University of California, Berkeley and his doctorate from The Johns Hopkins University. Most of his early research was on bird migration and orientation. After a stint teaching at Dickinson College in Pennsylvania, he moved to Hawaii in 1976 where he began work on endangered forest birds for the Forest Service as a Research Ecologist. In 1981 he and his family moved to Arcata to join the Forest Service's Redwood Sciences Laboratory. One of his principal research topics there has been on an old-growth dependent bird, the Marbled Murrelet, involving extensive research from Alaska to California. His other principal work is on landbird monitoring, especially involving census and constant effort mist netting. Since 1994 he has directed research at a bird monitoring station in Costa Rica, now one of the longest running stations in Latin America. Beginning in 1980 he conducted research on an island off New Zealand involving monitoring and reintroduction of native birds. He has published more than 150 scientific articles and edited several books on bird monitoring and the Marbled Murrelet.

Download or read book Metropolitan Denver written by Andrew R. Goetz and published by University of Pennsylvania Press. This book was released on 2018-09-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nestled between the Rocky Mountains to the west and the High Plains to the east, Denver, Colorado, is nicknamed the Mile High City because its official elevation is exactly one mile above sea level. Over the past ten years, it has also been one of the country's fastest-growing metropolitan areas. In Denver's early days, its geographic proximity to the mineral-rich mountains attracted miners, and gold and silver booms and busts played a large role in its economic success. Today, its central location—between the west and east coasts and between major cities of the Midwest—makes it a key node for the distribution of goods and services as well as an optimal site for federal agencies and telecommunications companies. In Metropolitan Denver, Andrew R. Goetz and E. Eric Boschmann show how the city evolved from its origins as a mining town into a cosmopolitan metropolis. They chart the foundations of Denver's recent economic development—from mining and agriculture to energy, defense, and technology—and examine the challenges engendered by a postwar population explosion that led to increasing income inequality and rapid growth in the number of Latino residents. Highlighting the risks and rewards of regional collaboration in municipal governance, Goetz and Boschmann recount public works projects such as the construction of the Denver International Airport and explore the smart growth movement that shifted development from postwar low-density, automobile-based, suburban and exurban sprawl to higher-density, mixed use, transit-oriented urban centers. Because of its proximity to the mountains and generally sunny weather, Denver has a reputation as a very active, outdoor-oriented city and a desirable place to live and work. Metropolitan Denver reveals the purposeful civic decisions made regarding tourism, downtown urban revitalization, and cultural-led economic development that make the city a destination.
Download or read book The Lessening Stream written by Michael F. Logan and published by University of Arizona Press. This book was released on 2006-09-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newcomers to Tucson know the Santa Cruz River as a dry bed that can become a rampaging flood after heavy rains. Yet until the late nineteenth century, the Santa Cruz was an active watercourse that served the region’s agricultural needs—until a burgeoning industrial society began to tap the river’s underground flow. The Lessening Stream reviews the changing human use of the Santa Cruz River and its aquifer from the earliest human presence in the valley to today. Michael Logan examines the social, cultural, and political history of the Santa Cruz Valley while interpreting the implications of various cultures' impacts on the river and speculating about the future of water in the region. Logan traces river history through three eras—archaic, modern, and postmodern—to capture the human history of the river from early Native American farmers through Spanish missionaries to Anglo settlers. He shows how humans first diverted its surface flow, then learned to pump its aquifer, and today fail to fully understand the river's place in the urban environment. By telling the story of the meandering river—from its origin in southern Arizona through Mexico and the Tucson Basin to its terminus in farmland near Phoenix—Logan links developments throughout the river valley so that a more complete picture of the river's history emerges. He also contemplates the future of the Santa Cruz by confronting the serious problems posed by groundwater pumping in Tucson and addressing the effects of the Central Arizona Project on the river valley. Skillfully interweaving history with hydrology, geology, archaeology, and anthropology, The Lessening Stream makes an important contribution to the environmental history of southern Arizona. It reminds us that, because water will always be the focus for human activity in the desert, we desperately need a more complete understanding of its place in our lives.
Download or read book Caryophyllales written by H.D. Behnke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Caryophyllales are one of the few higher taxa of the flowering plants ofwhich the size and delimitation against other taxa is undisputed. However, their derivation from other taxa and the evolution of families within this order in unsettled. "Systematics and Evolution of the Caryophyllales" reviews the important characters of this taxon emphasizing their contribution and influence towards a new proposal for both the putative origin of the order and the classification of its families. New results in molecular genetics, phytochemistry, ultrastructure, and morphology are provided and discussed in relation to both the classical and molecular systematics of the order. In addition, characters like betalains and sieve-element plastids, which have played a major role in shaping the size of the order, and others like DNA-data or flower morphologythat can be useful to discuss the position of the Caryophyllales within higher plants are critically evaluated.
Download or read book Ecoregions written by Robert G. Bailey and published by Springer Science & Business Media. This book was released on 2014-04-03 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming and human-driven impacts are changing the World’s ecological zones. This book applies the principles described in Bailey’s Ecosystem Geography: From Ecoregions to Sites, 2nd ed. (Springer 2009, 1st ed. 1996) to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Bailey’s system for classifying these zones has been adopted by major organizations such as the U.S. Forest Service and The Nature Conservancy and this book is a significant contribution to a long tradition of classifying and studying the world’s ecological regions or ecoregions. It includes two color maps that show the major ecoregions of the continents and oceans. Also included are: - 106 illustrations with 55 in full color - A new chapter on mountains is included. - There are new sections that address concerns about how eco regions are changing under the relentless influence of humans and climate change - Another new feature is the discussion of using eco regional patterns to transfer research results and select sites for detecting climate change effects on ecosystem distribution - Use of ecoregional patterns to design monitoring networks and sustainable landscapes - Fire regimes in different regional ecosystems and their management implications.
