Download or read book The Saguaro Cactus written by David Yetman and published by University of Arizona Press. This book was released on 2020-02-25 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The saguaro, with its great size and characteristic shape—its arms stretching heavenward, its silhouette often resembling a human—has become the emblem of the Sonoran Desert of southwestern Arizona and northwestern Mexico. The largest and tallest cactus in the United States, it is both familiar and an object of fascination and curiosity. This book offers a complete natural history of this enduring and iconic desert plant. Gathering everything from the saguaro’s role in Sonoran Desert ecology to its adaptations to the desert climate and its sacred place in Indigenous culture, this book shares precolonial through current scientific findings. The saguaro is charismatic and readily accessible but also decidedly different from other desert flora. The essays in this book bear witness to our ongoing fascination with the great cactus and the plant’s unusual characteristics, covering the saguaro’s: history of discovery, place in the cactus family, ecology, anatomy and physiology, genetics, and ethnobotany. The Saguaro Cactus offers testimony to the cactus’s prominence as a symbol, the perceptions it inspires, its role in human society, and its importance in desert ecology.

Available in PDF, EPUB and Kindle. Book excerpt: North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.

Available in PDF, EPUB and Kindle. Book excerpt: Although cacti such as the saguaro and organ pipe have come to define the Sonoran Desert for many people, they represent some 170 species of columnar cacti found in many parts of the Americas. These giant plants are so dominant in some ecosystems that many species of animals rely on them for food and shelter. They are pollinated by bats in central Mexico and Venezuela, by birds and bees in northern Mexico and Peru. This book summarizes our knowledge about the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists to show that the very survival of these cacti depends on animals who pollinate them and disperse their seeds. Contributors from the United States, Mexico, Venezuela, and Colombia explore aspects of geology and evolution that have forged this relationship, review findings in anatomy and physiology, and discuss recent research in population and community ecology as well as conservation issues. Ranging from the Sonoran Desert to the northern Andes, these studies reflect progress in understanding how abiotic and biotic factors interact to influence the evolution, distribution, and abundance of cacti and mutualists alike. In addition, this book examines the ways in which humans, through the process of domestication, have modified these plants for economic benefit. The contributors also review phylogenetic relationships between cacti and nectar-feeding bats in an effort to understand how bat-plant interactions have influenced the evolution of diversity and ecological specialization of both. Because of the number of migratory pollinators feeding on columnar cacti, the authors make conservation recommendations aimed at preserving fully functional ecosystems in arid portions of the New World tropics and subtropics. Columnar Cacti and Their Mutualists provided a benchmark for both conservation efforts and future research.

Book excerpt: The Sonoran Desert is a distinctive biotic region that fascinates scientist, students, and nature lovers. This book offers an accessible introduction to Sonoran Desert ecology. Eight original essays by Sonoran Desert specialists provide an overview of the practice of ecology at landscape, community, and organismal scales. The essays explore the rich diversity of plant life in the Sonoran Desert and the ecological patterns and processes that underlie it. They also reveal the history and scientific legacy of the Desert Laboratory in Tucson, which has conducted research on the Sonoran Desert since 1903. Coverage includes diversity and affinities of the flora, physical environments and vegetation, landscape complexity and ecological diversity, population dynamics of annual plants, form and function of cacti, and the relationship between plants and the animals that use them as feeding and breeding resources. The text also examines the ecological consequences of modern agricultural development, as well as the impact on the modern biota of 40,000 years of change in climate, vegetation, megafauna, and ancient cultures. This comprehensive book covers a broad range of spatial and temporal scales to highlight the diversity of research being pursued in the Sonoran Desert.

Download or read book Practical Ecology for Geography and Biology written by M. Gilbertson and published by Springer. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our aim in writing this book is to provide students and teachers with a simple introductory text which deals with practical aspects of ecology, environmen tal biology and biogeography, emphasizing actual field and classroom investigations. Basic concepts and methods of survey, mapping and aerial photography, data collection and data analysis are described and discussed, in order to encourage students to identify and tackle worthwhile projects. The level at which this text is appropriate depends very much upon particular circumstances. The greater part lies within the scope of the sixth form and the first and second years of college, polytechnic and university courses in the British Isles and their equivalents overseas. All students inevitably meet difficulties in the identification of plant and animal species, particularly when they venture into unfamiliar habitats and regions. This is often the cause of unnecessary alarm. Many ecological principles or problems may be illustrated by reference to familiar species and habitats, such as are found in urban environments, as well as those areas of semi-natural vegetation favoured for field courses.
Download or read book Science and Ecosystem Management in the National Parks written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."
