Download or read book The Changing Mile Revisited written by Raymond M. Turner and published by University of Arizona Press. This book was released on 2021-10-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Changing Mile, originally published in 1965, was a benchmark in ecological studies, demonstrating the prevalence of change in a seemingly changeless place. Photographs made throughout the Sonoran Desert region in the late 1800s and early 1900s were juxtaposed with photographs of the same locations taken many decades later. The nearly one hundred pairs of images revealed that climate has played a strong role in initiating many changes in the region. This new book updates the classic by adding recent photographs to the original pairs, providing another three decades of data and showing even more clearly the extent of change across the landscape. During these same three decades, abundant information about climatic variability, land use, and plant ecology has accumulated, making it possible to determine causes of change with more confidence. Using nearly two hundred additional triplicate sets of unpublished photographs, The Changing Mile Revisited utilizes repeat photographs selected from almost three hundred stations located in southern Arizona, in the Pinacate region of Mexico, and along the coast of the Gulf of California. Coarse photogrammetric analysis of this enlarged photographic set shows the varied response of the region's major plant species to the forces of change. The images show vegetation across the entire region at sites ranging in elevation from sea level to a mile above sea level. Some sites are truly arid, while others are located above the desert in grassland and woodland. Common names are used for most plants and animals (with Latin equivalents in endnotes) to make the book more accessible to non-technical readers. The original Changing Mile was based upon a unique set of data that allowed the authors to evaluate the extent and magnitude of vegetation change in a large geographic region. By extending the original landmark study, The Changing Mile Revisited will remain an indispensable reference for all concerned with the fragile desert environment.

This book was released on 2007-07-17 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thoroughly revised, entirely rewritten edition of what is the essential reference on California’s diverse and ever-changing vegetation now brings readers the most authoritative, state-of-the-art view of California’s plant ecosystems available. Integrating decades of research, leading community ecologists and field botanists describe and classify California’s vegetation types, identify environmental factors that determine the distribution of vegetation types, analyze the role of disturbance regimes in vegetation dynamics, chronicle change due to human activities, identify conservation issues, describe restoration strategies, and prioritize directions for new research. Several new chapters address statewide issues such as the historic appearance and impact of introduced and invasive plants, the soils of California, and more.
Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
Download or read book Vegetation Dynamics on the Mountains and Plateaus of the American Southwest written by John Vankat and published by Springer Science & Business Media. This book was released on 2013-05-27 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species
Download or read book White Tailed Deer Habitat written by Timothy Edward Fulbright and published by Texas A&M University Press. This book was released on 2013-05-08 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original, 2006 edition of Timothy Edward Fulbright and J. Alfonso Ortega-S.’s White-Tailed Deer Habitat: Ecology and Management on Rangelands was hailed as “a splendid reference for the classroom and those who make their living from wildlife and the land” and as “filling a niche that is not currently approached in the literature.” In this second, full-color edition, revised and expanded to include the entire western United States and northern Mexico, Fulbright and Ortega-S. provide a carefully reasoned synthesis of ecological and range management principles that incorporates rangeland vegetation management and the impact of crops, livestock, predation, and population density within the context of the arid and semiarid habitats of this broad region. As landowners look to hunting as a source of income and to the other benefits of managing for wildlife, the clear presentation of the up-to-date research gathered in this book will aid their efforts. Essential points covered in this new edition include: White-tailed deer habitat requirements Nutritional needs of White-tailed deer Carrying capacity Habitat management Hunting Focused across political borders and written with an understanding of environments where periodic drought punctuates long-term weather patterns, this revised and expanded edition of White-Tailed Deer Habitat: Ecology and Management on Rangelands will aid landowners, researchers, and naturalists in their efforts to integrate land management and use with sound ecological practices.
Download or read book When the Rains Come written by John Alcock and published by University of Arizona Press. This book was released on 2009-04-17 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life in the desert is a waiting game: waiting for rain. And in a year of drought, the stakes are especially high. John Alcock knows the Sonoran Desert better than just about anyone else, and in this book he tracks the changes he observes in plant and animal life over the course of a drought year. Combining scientific knowledge with years of exploring the desert, he describes the variety of ways in which the wait for rain takes placeÑand what happens when it finally comes. The desert is a land of five seasons, featuring two summersÑhot, dry months followed by monsoonÑand Alcock looks at the changes that take place in an entire desert community over the course of all five. He describes what he finds on hikes in the Usery Mountains near Phoenix, where he has studied desert life over three decades and where frequent visits have enabled him to notice effects of seasonal variation that might escape a casual glance. Blending a personal perspective with field observation, Alcock shows how desert ecology depends entirely on rainfall. He touches on a wide range of topics concerning the desertÕs natural history, noting the response of saguaro flowers to heat and the habits of predators, whether soaring red-tailed hawk or tiny horned lizard. He also describes unusual aspects of insects that few desert hikers will have noticed, such as the disruptive color pattern of certain grasshoppers that is more effective than most camouflage. When the Rains Come is brimming with new insights into the desert, from the mating behaviors of insects to urban sprawl, and features photographs that document changes in the landscape as drought years come and go. It brings us the desert in the harshest of timesÑand shows that it is still teeming with life.

This book was released on 2016-08-15 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Conservation in the Anthropocene provides thought-provoking insight into the ongoing environmental crises that climate change is generating and raises critical questions about how public and private land managers in North America will adapt to the climatological disruptions that are already transforming the ecological structures of these forests. In this pathbreaking anthology, a team of leading environmental researchers probes the central dilemmas that ecologists, forest land managers, state and federal agencies, and grassroots organizations are confronting—and will continue to confront—in the coming century. Each chapter examines strategies that are currently being tested across the country as scientists, citizen-scientists, policy makers, academics, and activists work to grasp their options and opportunities for a future that will be shaped by ongoing environmental upheaval. Successful adaptation to the challenges of climate change requires a transdisciplinary perspective. Forest Conservation in the Anthropocene provides a compelling set of arguments and case studies that underscores the need for innovative policies and energetic actions. Contributors: Craig D.

Download or read book White tailed Deer Habitat written by Timothy E. Fulbright and published by Texas A&M University Press. This book was released on 2005 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most of the last century, range management meant managing land for livestock. How well a landowner grew the grass that cattle ate was the best measure of success. In this century, landowners look to hunting and wildlife viewing for income; rangeland is now also wildlife habitat, and they are managing their land not just for cattle but also for wildlife, most notably deer and quail. Unlike other books on white-tailed deer in places where rainfall is relatively high and the environment stable, this book takes an ecological approach to deer management in the semiarid lands of Oklahoma, Texas, and northern Mexico. These are the least productive of white-tail habitats, where periodic drought punctuates long-term weather patterns. The book's focus on this landscape across political borders is one of its original and lasting contributions. Another is its contention that good management is based on ecological principles that guide the manager's thinking about: Habitat Requirements of White-Tailed Deer White-Tailed Deer Nutrition Carrying Capacity Habitat Manipulation Predators Hunting Timothy Edward Fulbright is a Regents Professor and the Meadows Professor in Semiarid Land Ecology at the Caesar Kleberg Wildlife Research Institute, Texas A&M University-Kingsville.

Download or read book Nesting Birds of a Tropical Frontier written by Timothy Brush and published by Texas A&M University Press. This book was released on 2005 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Halfway between Dallas and Mexico City, along the last few hundred miles of the Rio Grande, lies a subtropical outpost where people from all over the world come to see birds. Located between the temperate north and the tropic south, with desert to the west and ocean to the east, the Lower Rio Grande Valley of Texas provides habitat for a variety of birds seen nowhere else in the United States. If you want to see a Hooked-billed Kite, Muscovy Duck, or Altamira Oriole, this is the place." "Drawing on years of personal observation and study, Timothy Brush has written a classic work of natural history about the little-known breeding bird communities of the Valley and the diversity of nesting strategies and behaviors that can be seen. Brush estimates that there are more than 150 current breeding species in the Lower Rio Grande Valley. In Nesting Birds of a Tropical Frontier, he describes the habits, distribution, changes in occurrence, and general outlook of these as well as former breeders, concentrating on Valley specialties and other birds of particular interest in the Valley." "Art by Gerald Sneed and color photographs by several of Texas' top nature photographers show off some of the Valley's famous birds. Historical maps of vegetation and geology help us gain a better perspective on the changes that have taken place along the Rio Grande and on the breeding bird communities of the U.S.-Mexico frontier."--Jacket

Download or read book The Trees of Sonora Mexico written by Tucson Richard Stephen Felger Executive Director Drylands Institute, AZ and published by Oxford University Press, USA. This book was released on 2001-03-31 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive treatment of the trees and tree-like plants of Sonora, a remarkably diverse and biologically important region, ranging from some of the driest and hottest areas in North America to cool, temperate woodlands and the northernmost tropical regions in the New World. The majority of the trees in this semi-arid region are at their northern limits in the Americas in this state and many range to South America. Thus, this book will be important to biologists in regions well outside of the area covered. Felger is the recognized expert in the area, and the book contains an enormous body of information nowhere else obtainable. The introductory chapter contains biotic and climatic information and an analysis of the geographical distributions of the trees of a state that is poorly known biologically. Two hundred eighty-five species of native and naturalized trees are covered, featuring extensive identification keys and illustrations, most of them newly produced for this book. The descriptive species accounts include common names, indigenous names, and synonyms, detailed botanical descriptions, ecological and geographic data, geographic ranges, natural history, economic uses, and, in many cases, other information such as horticultural uses and conservation status.
Download or read book Postcards from the Baja California Border written by Daniel D. Arreola and published by University of Arizona Press. This book was released on 2021-10-05 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Postcards have a magical pull. They allow us to see the past through charming relics that allow us to travel back in time. Daniel D. Arreola’s Postcards from the Baja California Border offers a window into the historical and geographical past of storied Mexican border communities. Once-popular tourist destinations from the 1900s through the 1950s, the border communities explored in Postcards from the Baja California Border used to be filled with revelers, cabarets, curio shops, and more. The postcards in this book show the bright and dynamic past of California’s borderlands while diving deep into the historic and geographic significance of the imagery found on the postcards. This form of place study calls attention to how we can see a past through a serial view of places, by the nature of repetition, and the photographing of the same place over and over again. Arreola draws our focus to townscapes, or built landscapes, of four border towns—Tijuana, Mexicali, Tecate, and Algodones—during the first half of the twentieth century. With an emphasis on the tourist’s view of these places, this book creates a vivid picture of what life was like for tourists and residents of these towns in the early and mid-twentieth century. Postcards from the Baja California Border is a rich and fascinating experience, one that takes you on a time-travel journey through border town histories and geographies while celebrating the visual intrigue of postcards.
