Written by specialists in the field, the papers in this volume explore evolution of animals and plants on the deserts of North America, South America, and Australia. Together, the articles constitute a complete survey of the geological history of the deserts of three continents, the evolution of the animals and plants of those deserts, and their adaptations to the environments in which they live. The first paper, by Otto T. Solbrig, discusses the flora of the South American temperate and semidesert regions, citing numerous genera and reasons that they are found in the different areas. John S. Beard uses the same approach in his discussion of the evolution of Australian desert plants and focuses on western Australian areas. Guillermo Sarmiento appraises the evolution of arid vegetation in tropical America, including the Lesser Antilles and the Coast Range of Venezuela and Colombia. A. R. Main surveys the adaptation of Australian vertebrates to desert conditions and gives examples of how various species of birds, reptiles, and amphibians adapt to their environment in order for the greatest number to survive. James A. MacMahon designates specific communities in the Mojave, Sonoran, and Chihuahuan deserts and discusses the similarity of species of the North American desert mammal faunas found there, while Bobbi S. Low focuses on the evolution of amphibian life histories in the desert and compiles a lengthy table of amphibia comparing egg size, habitat, number of eggs per clutch, and so forth. Finally, W. Frank Blair treats adaptation of anurans to equivalent desert scrub of North and South America and cites various species of frogs and toads that are found in similar areas. The volume also includes an introduction by the editor and an index. Evolution of Desert Biota is the result of a symposium held during the First International Congress of Systematic and Evolutionary Biology in Boulder, Colorado; in August 1973.

"The village of Mark on the Somerset Levels is a watery wonderland, rich in wildlife: rooks and roe deer; sparrows and snowdrops; the iconic brown hare and the spectacular hummingbird hawk-moth. As the year unfolds, Stephen Moss witnesses the landscape as it passes from deep snow to spring blosson, through the heat haze of summer to the chill winds of autumn, from the first hazel catkins to the swallows returning from Africa. [This] is both the story of a small corner of the West Country and a celebration of the natural world."--Back cover.

Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. Highlights the complexity of global desert systems in a clear, concise way Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems

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 organism levels. 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.

This highly readable, spectacularly illustrated compendium is an ecological journey into a wondrous land of extremes. The California Deserts explores the remarkable diversity of life in this harsh yet fragile quarter of the Golden State. In a rich narrative, it illuminates how that diversity, created by drought and heat, has evolved with climate change since the Ice Ages. Along the way, we find there is much to learn from each desert species-- whether it is a cactus, pupfish, tortoise, or bighorn sheep--about adaptation to a warming, arid world. The book tells of human adaptation as well, and is underscored by a deep appreciation for the intimate knowledge acquired by native people during their 12,000-year desert experience. In this sense, the book is a journey of rediscovery, as it reflects on the ways that knowledge has been reclaimed and amplified by new discoveries. The book also takes the measure of the ecological condition of these deserts today, presenting issues of conservation, management, and restoration. With its many sidebars, photographs, and featured topics, The California Deserts provides a unique introduction to places of remarkable and often unexpected beauty.

Environmental and specific diversity in the Chihuahuan desert in general, and in the Cuatro Ciénegas Basin in particular, has long been recognized as outstanding. This book provides a global ecological overview, together with in-depth studies of specific processes. The Chihuahuan desert is the warmest in North America, and has a complex geologic, climatic and biogeographical history, which affects today’s distribution of vegetation and plants and generates complex phylogeographic patterns. The high number of endemic species reflects this complex set of traits. The modern distribution of environments, including aquatic and subaquatic systems, riparian environments, gypsum dunes and gypsum-rich soils, low levels of phosphorous and organic matter, and high salinity combined with an extreme climate call for a range of adaptations. Plants are distributed in a patchy pattern based on punctual variations, and many of them respond to different resources and conditions with considerable morphological plasticity. In terms of physiological, morphological and ecological variability, cacti were identified as the most important group in specific environments like bajadas, characterized by high diversity values, while gypsophytes and gypsovagues of different phylogenies, including species with restricted distribution and endemics.
