Available in PDF, EPUB and Kindle. Book excerpt: Most arches built today contain a single building block at the top that is the most important piece. This special piece can be found in the arches of soaring cathedrals, doorways in temples, and even simple buildings made out of wooden blocks. It is called a keystone, and it holds everything else together. Remove the keystone and the building or doorway is likely to collapse.The same thing is true in nature. Certain species of animals and plants are so important to their ecosystems, that if they disappear, the whole system may collapse. They are called keystone species.Some keystone species are large, like white rhinos, while others are quite small, like honey bees. But size doesn't matter in an ecosystem. All living things rely on other species to survive. A keystone species plays an especially large role that affects many different species in an ecosystem. Some keystone species are at the top of a huge ecosystem like the Greater Yellowstone Ecosystem, while others may affect a tiny ecosystem in a river or forest. Whether the ecosystem is big or small, the result of a keystone species disappearing or being greatly reduced is the same. Just like one falling domino can cause many others to fall, the loss of a keystone species can lead to the extinction of many other species.Today scientists are focusing more attention on preserving the natural balance in ecosystems. Identifying and protecting keystone species is an important part of their work.

Download or read book The Desert written by Michael Welland and published by Reaktion Books. This book was released on 2014-09-15 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: From endless sand dunes and prickly cacti to shimmering mirages and green oases, deserts evoke contradictory images in us. They are lands of desolation, but also of romance, of blistering Mojave heat and biting Gobi cold. Covering a quarter of the earth’s land mass and providing a home to half a billion people, they are both a physical reality and landscapes of the mind. The idea of the desert has long captured Western imagination, put on display in films and literature, but these portrayals often fail to capture the true scope and diversity of the people living there. Bridging the scientific and cultural gaps between perception and reality, The Desert celebrates our fascination with these arid lands and their inhabitants, as well as their importance both throughout history and in the world today. Covering an immense geographical range, Michael Welland wanders from the Sahara to the Atacama, depicting the often bizarre adaptations of plants and animals to these hostile environments. He also looks at these seemingly infertile landscapes in the context of their place in history—as the birthplaces not only of critical evolutionary adaptations, civilizations, and social progress, but also of ideologies. Telling the stories of the diverse peoples who call the desert home, he describes how people have survived there, their contributions to agricultural development, and their emphasis on water and its scarcity. He also delves into the allure of deserts and how they have been used in literature and film and their influence on fashion, art, and architecture. As Welland reveals, deserts may be difficult to define, but they play an active role in the evolution of our global climate and society at large, and their future is of the utmost importance. Entertaining, informative, and surprising, The Desert is an intriguing new look at these seemingly harsh and inhospitable landscapes.
Download or read book The Astonishing Astounding Amazing Sonoran Desert written by Andrew T Smith and published by . This book was released on 2019-07-12 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "The Astonishing, Astounding, Amazing Sonoran Desert" presents an entertaining introduction to the Sonoran Desert ecosystem, designed for visitors who want a quick read about the Sonoran Desert and its wildlife. Vibrant full-page color illustrations capture the colors of the desert and behavior of its wildlife. The Sonoran Desert differs from other deserts. Readers learn how having two rainy seasons and more rainfall on average than other deserts have produced a landscape far richer in plant and animal life than is typically found in other deserts. Accounts of 20 species that live in or migrate to the Sonoran Desert are featured with fascinating natural histories that readers might not have heard of before._Learn about the grasshopper mouse, which is carnivorous and howls at the night sky; the white-winged dove, which migrates to the Sonoran Desert during the hottest time of year to feast on the flowers and fruit of saguaro cacti; and desert termites, without which the Sonoran Desert would be knee-deep in cow dung. These accounts and others show how native plants and animals have adapted to the high temperatures and scarcity of water characteristics of the Sonoran Desert._The book concludes with a description of the threats to the Sonoran Desert and what citizens can do about them. Learn about the negative impact of invasive species including sunfish and buffelgrass on native species. Open-pit mines and border barriers are some examples of human disturbance that adversely affect plants, animals, and fragile desert soils. Finally, read how climate change, if not addressed, could eventually convert the desert into a wasteland. Acknowledging climate change and actively conserving the desert now is our best hope for protecting this astonishing, astounding, and amazing ecosystem for the future.

Download or read book Flora of the Gran Desierto and R o Colorado Delta written by Richard Stephen Felger and published by University of Arizona Press. This book was released on 2023-02-07 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Pinacate lava fields and expansive dunes to the shores of the Gulf of California, the Gran Desierto is one of the hottest and driest places in the Western Hemisphere. Yet this region in the state of Sonora in northwestern Mexico embraces a remarkable number of habitats with a fascinating and surprisingly rich flora. This is the heart of the Sonoran Desert, still in a largely primordial state, in juxtaposition with the ravished wetlands of the once great Río Colorado. Flora of the Gran Desierto is the culmination of more than twenty-five years of research in this magnificent desert and delta by botanist Richard Felger. This comprehensive floristic study of more than 565 species of vascular plants features original diagnostic descriptions and innovative identification keys to the families, genera, and species. Particular attention has been devoted to taxa that are poorly known. Even weeds and their histories are treated in detail. Hundreds of illustrations by such eminent botanical artists as Lucretia Brezeale Hamilton, Matt Johnson, and Bobbi Angell will aid in the identification of plants. Common names of plants are given in English, Spanish, and O'odham. While emphasizing scientific accuracy, the book is written in an accessible style. Felger's observations and knowledge of plant ecology, geographic distribution, evolution, ethnobotany, plant variation and special adaptations, and the history of the region provides botanists, naturalists, ecologists, conservationists, and anyone else celebrating the desert with readable, interesting, and important information. With two of Mexico's newest biosphere reserves—the Pinacate and the Upper Gulf of California—this region is a keystone for desert conservation efforts. Its location linking vast preserves to the north makes this book especially useful for anyone interested in borderland studies and the Sonoran Desert. Flora of the Gran Desierto represents a most creative, definitive, and enthusiastic treatment of Sonoran Desert plant life and is highly relevant to ecological restoration in deserts and wetlands in arid places worldwide.

Download or read book Biodiversity and Ecosystem Function written by Ernst-Detlef Schulze 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: The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.
Download or read book The Vegetation of Egypt written by M.A. Zahran and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The first treatise on the flora of Egypt, by Petrus Forsskäl, was published in 1775. Records of the Egyptian flora made during the Napoleonic expedition to Egypt (1778-1801) were provided by AR. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be re cognized. The first was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836-1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xerophytism. These two traditions were maintained and expanded in further phases of ecological development associated with the es tablishment of the Egyptian University in 1925 (now the University the Swedish Gunnar of Cairo). The first professor of botany was Täckholm (1925-1929). He died young, and his wife Vivi Täckholm devoted her life to studying the flora of Egypt and gave leadership and inspiration to plant taxonomists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W. Oliver (1929- 1932) followed by the British ecologist F. J. Lewis (1935-1947).
Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

Download or read book Rewilding the World written by Caroline Fraser and published by Metropolitan Books. This book was released on 2014-04-29 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gripping account of the environmental crusade to save the world's most endangered species and landscapes—the last best hope for preserving our natural home Scientists worldwide are warning of the looming extinction of thousands of species, from tigers and polar bears to rare flowers, birds, and insects. If the destruction continues, a third of all plants and animals could disappear by 2050—and with them earth's life-support ecosystems that provide our food, water, medicine, and natural defenses against climate change. Now Caroline Fraser offers the first definitive account of a visionary campaign to confront this crisis: rewilding. Breathtaking in scope and ambition, rewilding aims to save species by restoring habitats, reviving migration corridors, and brokering peace between people and predators. Traveling with wildlife biologists and conservationists, Fraser reports on the vast projects that are turning Europe's former Iron Curtain into a greenbelt, creating trans-frontier Peace Parks to renew elephant routes throughout Africa, and linking protected areas from the Yukon to Mexico and beyond. An inspiring story of scientific discovery and grassroots action, Rewilding the World offers hope for a richer, wilder future.
Download or read book The Biology of Deserts written by David Ward and published by Oxford University Press. This book was released on 2016-06-16 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.
Download or read book Desert Puma written by Kenneth A. Logan and published by Island Press. This book was released on 2001-08-01 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists and conservationists are beginning to understand the importance of top carnivores to the health and integrity of fully functioning ecosystems. As burgeoning human populations continue to impinge on natural landscapes, the need for understanding carnivore populations and how we affect them is becoming increasingly acute.Desert Puma represents one of the most detailed assessments ever produced of the biology and ecology of a top carnivore. The husband-and-wife team of Kenneth Logan and Linda Sweanor set forth extensive data gathered from their ten-year field study of pumas in the Chihuahua Desert of New Mexico, also drawing on other reliable scientific data gathered throughout the puma's geographic range. Chapters examine: the evolutionary and modern history of pumas, their taxonomy, and physical description a detailed description and history of the study area in the Chihuahua Desert field techniques that were used in the research puma population dynamics and life history strategies the implications of puma behavior and social organization the relationships of pumas and their preyThe authors provide important new information about both the biology of pumas and their evolutionary ecology -- not only what pumas do, but why they do it. Logan and Sweanor explain how an understanding of puma evolutionary ecology can, and must, inform long-term conservation strategies. They end the book with their ideas regarding strategies for puma management and conservation, along with a consideration of the future of pumas and humans. Desert Puma makes a significant and original contribution to the science not only of pumas in desert ecosystems but of the role of top predators in all environments. It is an essential contribution to the bookshelf of any wildlife biologist or conservationist involved in large-scale land management or wildlife management.
