Download or read book Behavioural Adaptations of Desert Animals written by Giovanni Costa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: After a brief survey of biotopic and vegetational features and an account of the main groups of desert animals, the most unusual patterns of the behaviour of the xerophilous fauna are examined. The importance of the thermohygric regulation and self-protective and locomotor mechanisms to the survival of arid-adapted animals is emphasized and various adaptations in the alimentary, reproductive and social spheres are analyzed. The clear and fluent treatment will awaken the interest of the reading public, from the amateur naturalists to research scientists.

Download or read book Environmental Physiology of Animals written by Pat Willmer and published by Wiley-Blackwell. This book was released on 2000-02-28 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new text provides a fresh approach to the subject of animal physiology, truly integrating comparative and environmental aspects for the first time. The book is divided into three sections: the first covers the basic principles of adaptation and problems of size and scale; the second tackles the key mechanisms in comparative physiology; and the third considers in detail how organisms (both vertebrate and invertebrate) cope with particular environments. Throughout this final section, relevant comparative aspects are given prominence in boxes so that interesting topics can be explored in greater depth. Several textbooks deal with the physiological functioning and comparative adaptations of animals, but this one is different: Includes both comparative systems physiology (basic principles and mechanisms of excretion, thermal biology, respiration, etc) and environmental physiology (problems of life in different habitats), with easy cross-reference between the two. Analyses and integrates problems and adaptations for each kind of environment: marine, seashore and estuary, freshwater, terrestrial and parasitic. For example, it explains how seashore animals survive both tidal submersion in cold salt water and exposure to warm dry air, cope with wide variations in salinity and temperature and achieve both aerial and underwater breathing. Examines mechanisms and responses beyond physiology. It analyses the costs of different types of locomotion, together with the mechanical challenges and varying sensory needs imposed by different environments. Behavioural responses to environmental challenges are considered, including the evolution of mating systems and life-history strategies, as well as responses to stresses imposed by humans. The book therefore integrates the biochemical, physiological, behavioral and ecological adaptations that allow animals to survive in particular environments. Applies an evolutionary perspective to the analysis of environmental adaptation. It introduces modern, phylogeny-based comparative methods that have become standard techniques in the analysis of evolutionary patterns. Provides modern molecular biological insights into the mechanistic basis of adaptation, and takes the level of analysis beyond the cell to the membrane, enzyme and gene. Incorporates more varied material from a wide range of animal types, with less of a focus purely on terrestrial reptiles, birds and mammals and more on the spectacularly successful strategies of invertebrates. This is a core text for modern undergraduate courses in animal physiology, comparative physiology, environmental physiology and physiological ecology. It is also suitable for the physiological components of any animal biology course, and a key resource for degree courses in environmental biology.

Download or read book Ecology of Desert Systems written by Walter G. Whitford and published by Elsevier. This book was released on 2002-03-25 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional wisdom considers deserts stark, harsh regions that support few living things. Most people also believe that water alone makes the desert bloom. Ecology of Desert Systems challenges these conventional views. This volume explores a broad range of topics of interest to ecosystem, population, community, and physiological ecologists. Climate, weather patterns, geomorphology, and wind and water processes are examined as variables that affect the distribution of biota through fundamental ecosystem processes. Descriptions of morphological, behavioral, and physiological adaptations of desert biota illuminate, through the lens of patch dynamics, principles for understanding observed patterns of primary production, nutrient cycling, and the effects of consumers. Desertification, and the techniques for monitoring and quantifying it, is examined within the framework of desert ecosystem patterns and processes. * Focuses on the interactions of climate, soil, and biota along a spectrum of spatial and temporal scales * Details the role of animals in desert ecosystems and landscape processes * Examines watershed scale processes, the ecology of ephemeral lakes, and the ecological changes identified with desertification * Outlines the fundamental concepts relevant to sustainable development of arid lands

Download or read book Ecology of Desert Organisms written by Gideon Louw and published by Longman Publishing Group. This book was released on 1982 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this book the authors consider the ecology of desert organisms. They have illustrated the principles involved with a selection of interesting examples from a wide body of research and from their own experience. In their study they have given equal emphasis to physiological ecology and population ecology. They have looked both at the way organisms avoid the extremes of the desert environment and at adaptations in their morphology, physiology and behaviour which make them better able to tolerate the unfavourable conditions. Reproduction and the dynamics, structure and evolution of desert communities are also discussed in detail, and in the concluding chapter the authors consider the increasingly important role of man in shaping the desert environment. The book provides a broad synthesis of the major principles of ecology, and with its balance between the botanical and zoological aspects of the subject, it will be of value to life scientists in general. Students wishing to broaden their knowledge of ecology as well as the reader interested in desert biology will find here a wealth of fascinating material in a clear and concise form" -- Back cover

Download or read book Tropical Biology and Conservation Management Volume IX written by Kleber Del Claro and published by EOLSS Publications. This book was released on 2009-05-11 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

This book was released on 2012-12-06 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: I have spent less time in the arid zone in the last few years than I did during the 1960's, 1970's and early 1980's. This results from a progression through age and a career structure which gradually shifted the emphasis of my work from being essentially field-oriented to essentially office-hound. When, therefore, I was asked by John Cloudsley-Thompson to undertake the writing of this hook I hesitated for two reasons. One reason was that, although I now had access to good library facilities and kept up with the literature on the arid zones and their fauna, I was not sure that a sedentary and pleasant life in a temperate highland island in tropieal Africa would provide a mental attitude suitable to writing a hook which related to areas where life is usually nomadie and often extremely disagreeable. The other reason was that I was uncertain whether I could devote the time necessary to researehing and writing the hook on top of my professional (which now specifical ly excluded research in the arid zones and on camels) and social (new-found and time-consuming) commitments. In the event I accepted and the fates were kind to me. By some peculiar combination of circumstances I was given the opportunity to spend a considerable part of the first half of 1988 in some of the driest areas of the globe. I had already visited all of the locations used for the construction of Fig. 2.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract Biological vision is a rather fascinating domain of research. Scientists of various origins like biology, medicine, neurophysiology, engineering, math ematics, etc. aim to understand the processes leading to visual perception process and at reproducing such systems. Understanding the environment is most of the time done through visual perception which appears to be one of the most fundamental sensory abilities in humans and therefore a significant amount of research effort has been dedicated towards modelling and repro ducing human visual abilities. Mathematical methods play a central role in this endeavour. Introduction David Marr's theory v^as a pioneering step tov^ards understanding visual percep tion. In his view human vision was based on a complete surface reconstruction of the environment that was then used to address visual subtasks. This approach was proven to be insufficient by neuro-biologists and complementary ideas from statistical pattern recognition and artificial intelligence were introduced to bet ter address the visual perception problem. In this framework visual perception is represented by a set of actions and rules connecting these actions. The emerg ing concept of active vision consists of a selective visual perception paradigm that is basically equivalent to recovering from the environment the minimal piece information required to address a particular task of interest.
