Download or read book Homeostasis in Desert Reptiles written by Sidney Donald Bradshaw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deserts, whether hot or cold, are considered to be one of the most difficult environments for living systems, lacking the essential free water which ac counts for approximately 60-70% of their body mass and more than 98% of their constituent atoms {Macfarlane 1978}. Amongst vertebrates, reptiles are usually thought of as the animals most adapted or suited to such environments because of their diurnal habit, based on a need for external heat, and their ability to survive far from obvious sources of water. This impression is rein forced when one examines the composition of vertebrate faunae characteristic of deserts and arid zones: reptiles predominate and they are often the only vertebrates to be found in hyper-arid areas, such as some parts of the Sahara {Monod 1973}. I recently had occasion to examine this assumption carefully, however, and was led inexorably to the conclusion that reptiles represent a particularly successful desert group, not because of their evolution of superior adaptations, but because of their possession of a basic suite of behavioural and physiologi cal characteristics that suit them uniquely to this very resource-limited environment {Bradshaw 1986a}. These fundamental reptilian characteristics are: 1. their low rates of metabolism, compared with birds and mammals, which result in extremely low rates of resource utilisation and lead to considerable economy in the handling of water 2.
Download or read book Ecophysiology of Desert Arthropods and Reptiles written by John L. Cloudsley-Thompson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecophysiology of Desert Arthropods and Reptiles starts with a new classification of the world's deserts, based upon the type of precipitation and the effect on their faunas of arthropods and reptiles. This is followed by an account of microclimates and the avoidance of environmental extremes. Whereas thermoregulation is primarily behavioural, responses to water shortage are largely physiological. Seasonal activity and phenology are described, adaptations for burrowing, the avoidance of enemies, and defence, are also outlined. A comparative account of interspecific relationships, feeding specializations, and species diversity in the two taxa is described. The purpose of the book is to provide a new and up-to-date analysis that will stimulate further research along these lines.

Download or read book Nomadic Desert Birds written by W. Richard J. Dean and published by Springer Science & Business Media. This book was released on 2004 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two basic strategies for coping with life in the desert. The first involves withstanding the extreme conditions using behavioural or physiological tactics. The second strategy is to be a migrant and to opportunistically or seasonally move to where the necessary resources are. Nomadism, i.e. the opportunistic and irregular movements from resource-poor to resource-rich patches, is a tactic that birds, with their mobility, can use, and it is explored by W.R.J. Dean in this volume. For many bird species, such movements between habitats or across landscapes to find patches of resources are essential for their continued existence. The relationship between climate, habitat and movements in the avifauna of arid and semi-arid regions and the advantages and disadvantages of a seasonally migratory or opportunistically nomadic lifestyle are elucidated.
Download or read book Avian Desert Predators written by William E. Cook and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike mammals, birds are not particularly well suited to desert life. Among the few types of birds that have successfully adapted to the desert ecosystem are the predators. With individual chapters devoted to each of the different species, the book explores those attributes which make this group suited to desert life, and how they have developed their abilities to cope with the prevailing harsh conditions. This readily accessible volume collates a substantial amount of the latest research on this fascinating subject.
Download or read book On the Ecology of Australia s Arid Zone written by Hans Lambers and published by Springer. This book was released on 2018-08-21 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will appeal to an international audience as well as be irresistible to local readers. Anyone working or with an interest in Australia’s arid zone should need ready access to this book. There is no equivalent publication out there at the moment, and this book has many authoritative chapters, richly illustrated with colourful material. The challenge of this book was to assemble current knowledge on particular topics and concepts, and principles relating to them. It is also forward-looking by identifying where there are gaps or inadequacies in knowledge, and where future research needs to be directed. Lead authors were encouraged to take such an approach; they had the opportunity to involve any author they considered appropriate. The final product shouldbe a fabulous resource, also for university courses, especially at MSc level.
Download or read book Survival Strategies of Annual Desert Plants written by Yitzchak Gutterman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.
Download or read book Desert Arthropods Life History Variations written by Fred Punzo and published by Springer Science & Business Media. This book was released on 1999-12-14 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Spatial Ecology of Desert Rodent Communities written by Georgy I. Shenbrot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rodents are conspicuous and important components of the desert biome. Many general concepts in modern community and behavioral ecology use them as a main model. This volume compiles and generalizes data on the spatial structure of desert rodent communities, taking into account both global (biogeographic) and local (ecological) patterns. It is based on studies of rodents in different deserts of the Northern Hemisphere (Karakum, Kyzylkum, Bet-Pak-Dala, Gobi, Thar, Chihuahua, Negev, and North Caspian deserts) as well as on a thorough analysis of the literature.
Download or read book Dispersal Biology of Desert Plants written by Karen van Rheede van Oudtshoorn and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dispersal processes have important effects on plant distribution and abundance. Although adaptations to long range dispersal (telechory) are by no means rare in desert plants, many desert plant species do not possess any features to promote dispersal (atelechory), while others have structures that hamper dispersal (antitelechory). The high frequency with which atelechorous and antitelechorous mechanisms are present in plants inhabiting arid areas indicates the importance of these adaptations. Among the benefits derived from these adaptations are the spreading of germination over time, the provision of suitable conditions for germination and subsequent seedling establishment, and the maintenance of a reservoir of available seeds (seed bank). This book describes the ways and means - anatomical, morphological and ecological - by which dispersal in desert plants has evolved to ensure the survival of these species in their harsh and unpredictable environment.
Download or read book Ecophysiology of Small Desert Mammals written by Allan A. Degen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since small mammals have a large surface to mass ratio, one would expect them to quickly dehydrate and perish at high environmental temperatures. Nonetheless, a large number of small mammal species inhabit deserts. This fascinating phenomenon is investigated by Prof. A. Allan Degen in his book. The majority of small desert mammals are rodents, but shrews of several grams and small foxes of 1 kg are also present. Their survival is due mainly to behavioural adaptations and habitat selection, however, physiological adaptations also contribute to the success. Interestingly, many small mammals that live in different deserts of the world show similarities in their adaptive traits although they have different taxonomic affinities.
