Desert Biology: Special Topics on the Physical and Biological Aspects of Arid Regions, Volume II records the conditions and life in the arid regions of the world. This book discusses the hydrogeology of arid regions, desert soil surfaces and classes, and physical and vegetational aspects of the Sahara Desert. The Piman Indians of the Sonoran Desert, approach to the water relations of desert plants, desert arthropods, and aquatic environments of deserts are also considered. Other topics include the artificial changes in the hydrogeology of deserts, soils of individual world deserts, rainfall and water supply of desert plants, and ecological plant types in arid regions. The hydrature in true xerophytes, chloride accumulation in halophytes, and biological response to desert water conditions are likewise covered in this publication. This volume is recommended for researchers and specialists interested in the hot, dry regions of the planet.

Deserts appear very fascinating during our short visits. However, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. The editor of this book was born and brought up in the Great Indian Desert, and has spent much of his life studying the growth and metabolism of desert plants. It is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. It has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. In this book, I have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. The scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. Therefore, there are chapters devoted to medicinal plants (Chap. 1), halophytes (Chaps. 13, 14), and fruit plants (Chaps. 17, 20). Desert plants have a unique reproductive biology (Chaps. 9–11), well-adapted eco-physiological and anatomical charact- istics (Chap. 7), and specialised metabolism and survival abilities. These plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (Chaps. 18–20).

This volume summarizes our current understanding of biological soil crusts (biocrusts), which are omnipresent in dryland regions. Since they cover the soil surface, they influence, or even control, all surface exchange processes. Being one of the oldest terrestrial communities, biocrusts comprise a high diversity of cyanobacteria, algae, lichens and bryophytes together with uncounted bacteria, and fungi. The authors show that biocrusts are an integral part of dryland ecosystems, stabilizing soils, influencing plant germination and growth, and playing a key role in carbon, nitrogen and water cycling. Initial attempts have been made to use biocrusts as models in ecological theory. On the other hand, biocrusts are endangered by local disruptions and global change, highlighting the need for enhanced recovery methods. This book offers a comprehensive overview of the fascinating field of biocrust research, making it indispensable not only for scientists in this area, but also for land managers, policy makers, and anyone interested in the environment.

"This title presents new research on the Mojave Desert and the contributors discuss the desert from several perspectives including regional threats such as expanding human populations, climate change, atmospheric nitrogen deposition and invasive plants, the impact of roads in a desert ecosystem, soils and plant communities, shrinking aquifers and the monitoring and sustainability of this fragile ecosystem."--NHBS Environment Bookstore.

It is difficult for me to recollect a time when I was not fascinated with the very notion of a desert. Walt Disney's film, The Living Desert, which I initially saw when I was 8 years of age, provided me with my first glimpse of this wondrous yet seemingly ho stile environment. The images were hypnotic and captivating. I looked on in amazement at the promenade Cl deux of the male and female scorpions during courtship. Their rhythmic and coordinated movements as they grasped one another made them appear to glide in unis on over the surface of the sand, each individual totally absorbed with its partner. In the next minute the fern ale had suddenly and utterly transformed herself like some Jekyll and Hyde act, into an aggressive predator whose prior gregarious embrace was now a hold of death for the male. The indomitable desert grasshopper mouse, the ever sentient kit fox, the graceful shovel-nosed snake swimming in an endless sea of sand.

The book aims to provide an unifying view of a variety (a 'zoo') of mathematical models with some kind of singular nonlinearity, in the sense that it becomes infinite when the state variable approaches a certain point. Up to 11 different concrete models are analyzed in separate chapters. Each chapter starts with a discussion of the basic model and its physical significance. Then the main results and typical proofs are outlined, followed by open problems. Each chapter is closed by a suitable list of references. The book may serve as a guide for researchers interested in the modelling of real world processes.
