Zustand: Very Good. xvi, 515, 1 col plates, b/w photos, text figs. . HB. Vg in d/w (short score mark to rear panel). 1st edition. This volume brings together more than a decade of information collected in the field and lab on the naked mole-rat (Heterocephalus glaber), a northeast African mammal unique for its physical characteristics and eusociality. Nearly blind and virtually hairless, naked mole-rats inhabit large subterranean colonies in which only one female and her one to three mates conceive offspring, while the young from previous litters maintain and defend the group as do workers in colonies of the social insects. In this first major treatise on naked mole-rats an international group of researchers covers such topics as the evolution of eusociality, phylogeny and systematics of the rodent family Bathyergidae, population and behavioral ecology and genetics of naked mole-rats in the field, vocal and nonvocal behaviors, social organization and divisions of labor within colonies, and climatic, social, and physiological factors affecting growth, reproduction, and reproductive suppression. In addition to the editors, the contributors are D. H. Abbott, M. W. Allard, N. C. Bennett, R. A. Brett, S. H. Braude, B. Crespi, S. V. Edwards, C. G. Faulkes, L. M. George, R. L. Honeycutt, E. A. Lacey, C. E. Liddell, E. McDaid, K. Nelson, K. M. Noonan, J. O'Riain, J. W. Pepper, H. K. Reeve, and D. A. Schlitter. [9780691085852].

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The theory of ecological convergence underlies the biogeographers' maps of world biome-types. It also determines the degree to which ecological principles, derived from research on particular populations, communities or ecosystems, are generally valid, and hence also to what extent resource management principles are general. To quote Di Castri and Mooney (1973): 'In effect, in order to assess the transfer of technology, it is essential to know to what extent information acquired from studying one particular ecosystem is applicable to another ecosystem of the same type but situated in a different location. ' The five relatively small, isolated, mediterranean-climate zones of the earth, each with its distinct fauna and flora, have provided the ideal testing grounds for this theory. A heritage of precisely focused ecosystems research has resulted, beginning with the international comparative analyses conducted by Specht (l969a, b) but with antecedents in earlier studies in South Australia (Specht and Rayson 1957, Specht 1973). Cody and Mooney (1978) reviewed the information available at the time for the four zones excepting Australia and concluded that the arrays of strategy-types to be found among the different biotas were so similar that they could be explained only in terms of the convergence hypothesis; nevertheless, evident differences in community organization and dynamics, especially phenol ogy, required closer study of resource availability and resource-use patterns to better explain relations between form and function overall, and to assess the degree of convergence at higher levels of organization than the population.
