Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The hand commonly is considered to have exerted great influence on the evolution of typically human characteristics, like upright posture, stereoscopic vision, 'manipulative' handling of parts of the environment. The German term 'Begreifen', which is commonly used for the understanding of complex relationships in a generalised, abstract sense, always implies the original meaning of seizing objects with the aid of the hands. The hands are also of greatest importance for the survival of the other, non-human primates. Hands are absolutely essential for locomotion in an arboreal habitat, and the intake of food is dependant on the use of the hands as well: primates very rarely take in food directly with their mouths, in the wast majority of cases they seize food items with their hands. Even drinking is often performed by dipping the hand into the water and licking the drops from hand and forearm. An organ of such importance will very probably be 'adapted' to its 'function'. This statement is made so often, that any further considerations seem superfluous. Nobody doubts, that the hands of primates are highly adaptive organs, the general form and internal structure of which are closely related to the necessities of life. However, if one tries to go beyond this general statement, he finds himself confront ed with several problems: First of all, a point which W. GUTMANN has emphasized repeatedly: according to the results obtained by genetics, the first thing to appear is the mutated character.…

Zustand: Sehr gut. Zustand: Sehr gut | Seiten: 392 | Sprache: Englisch | Produktart: Bücher | The prirnates that provide the central theme of these studies by David Chivers and his colleagues are the dominant large herbi­ vores of the tropical evergreen rain forest. Tothis extent, they are the ecological counterparts of the great herds of ungulates in­ habiting the savannahs of tropical Africa (and the monsoonal plains of Asia in their pristine state). Both groups comprise the chief primary consumers of living vegetable tissue in their respective environments. Members of each show appropriate anatomical adapt­ ations for such a diet. As efficient exploiters of a dispersed but generally abundant food source, each group collectively forms the main vertebrate component of animal biernass in the environment. Yet, despite superficial convergence, there are important differences in the biology and behaviour of members of these two groups of herbivores. Of greatest practical moment to the enquiring biologist are the ready visibility of most plains-dwelling ungulates, the ease with which the researcher can travel over (or above) their habitat by motor transport (or light aircraft) and the facility for near approach without causing disturbance that a closed vehicle has proved to offer. Given the additional attractions of wide, open views and stupendaus scenery, generally invigorating climate and easy life-style, it is perhaps not surprising that in past decades much research effort has focussed on the larger herbivorous mammals of the tropical savannahs.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book results from a two-day symposium and three-day workshop held in Cambridge between March 22nd and March 26th 1982 and sponsored by the Primate Society of Great Britain and the Anatomical Society of Great Britain and Ireland. More than 100 primatologists attended the symposium and some 35 were invited to participate in the workshop. Speakers from Prance, Germany, the Netherlands, South Africa and the U. S. A. , as weIl as the U. K. , were invited to contribute. In recent years feeling had strengthened that primatologists in Europe did not gather together sufficiently often. Distinctive tradit ions in primatology have developed in Germany, France, the Netherlands, Italy and the U. K. in particular, and it was feIt that attempts to blend them could only benefit primatology. Furthermore, studies of primate ecology, behaviour, anatomy, physiology and evolution have reached the points where further advances depend on inter-disciplinary collaboration. It was resolved to arrange a regular series of round table discussions on primate biology in Europe at the biennial meeting of the German Society for Anthropology and Human Genetics in Heidel berg in September 1979, where Holger Preuschoft organised sessions on primate ecology and anatomy. In June 1980 Michel Sakka convened a most effective working group in Paris to discuss cranial morphology and evolution. In 1982 it was the turn of the U. K.…

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - However well the anatomy of the gastrointestinal tracts of a wide range of mammals are described and quantified, there can be no real explanation of observed patterns without consideration of the mechanical and chemical properties of the food consumed, and digestive stages involved in its processing. This book aims to integrate findings from the many different types of investigations of mammalian digestive systems into a coherent whole. Using the themes of food, form and function, researchers discuss models of digestive processes, linking this with evolutionary aspects of food utilization. Macroscopic and ultrastructural studies of the gastrointestinal tract are also presented, as are physiological, ecological and biochemical aspects of the digestion of different food types. The book ends with an integrative chapter, bringing together the themes running through the earlier sections.…
