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.

This new series for the very young highlights the defining characteristics of habitats, including the plant and animal life, using examples from around the world.Award-winning author Cathryn Sill and her husband, noted wildlife illustrator John Sill, offer young readers a first glimpse into desert habitats.In simple, easy-to-understand language, this guide teaches children what deserts are, what kinds of animals and plants live there, and how certain species have adapted to the unique challenges of surviving in this harsh environment.John Sill's beautifully detailed, full-color illustrations reflect the diversity of desert topography-- from the vast dunes of the Arabian Desert to the rocky Chihuahuan Desert in the southwestern U.S.-and the astonishing varieties of desert wildlife. A glossary and afterword provide young readers with further fascinating details on the desert, its creatures, and its conditions.

BIOLOGY IS THE STUDY OF LIFE Life is everywhere, thriving in the city and in the country, teeming in ecosystems around the planet—in deserts, oceans, and even the Arctic. And life is right outside your door! Backyard Biology invites children ages 9 and up to investigate living things—especially in yards, parks, nature areas, and playgrounds. Trivia and fun facts bring animals, plants, and microorganisms to life, in all their wonder. Readers become Nature Detectives with activities and projects that encourage children to make discoveries. Children will construct a plankton net to collect pond samples, and they’ll grow microorganisms in a Winogradsky Column. They’ll discover what mystery plants sprout from collected soil samples and build a rolypoly habitat. When children experiment with phototropism and geotropism, they'll discover the ways plants move. In Backyard Biology, children will scout out different habitats to observe and investigate—and do their part to protect them.

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

An easy-to-read, beautifully illustrated undergraduate-level introduction to fresh- and running-water biology. Each chapter includes practical information on simple studies and experiments for students to try. The text begins with the physical features that define running water (lotic) habitats then continues with organisms that inhabit these habitats, and concludes with a discussion of applied issues surrounding water use, including pollution, species diversity, and conservation. The authors outline the range of living organisms in lotic habitats, and the environmental adaptations they exhibit. They discuss population, community, and ecosystem patterns and processes, such as energy flow, nutrient cycling, migration, food webs, and community structure. Particular consideration is given to links between stream and river channels and their surrounding landscapes, to short-term and seasonal changes, and to historical and biogeographical factors. The text concludes with a section of additional practical field work activities and a list for further reading.

Desert Biology: Special Topics on the Physical and Biological Aspects on Arid Regions, Volume I covers the biology, geophysical characteristics, and ways of life in arid regions. This book is composed of 11 chapters, and begins with a brief description of a desert community, the Merkhiyat Jebels, with its diverse fauna and flora. The subsequent chapters look into the climate, geographical distribution, geologic and geomorphic aspects, and the evolution of desert community. These topics are followed by intensive discussions on desert plants, animals, and limnology. The last chapter describes the adaptive processes and human adaptation capacity to arid environments. This book will prove useful to upper division and graduate students in desert biology.
