Alcock john (737 risultati)

Hardback. Condizione: Fair. What could seem less inviting than summer in the desert? For most people, this prospect conjures up the image of relentless heat and parched earth; for biologist John Alcock, summer in Arizona's Sonoran Desert represents an opportunity to investigate the wide variety of life that flourishes in one of the most extreme environments in North America. Only very special plants and animals can survive and reproduce in a place that may receive as little as six inches of rain in a year, observes Alcock, a place where the temperature may rise above one hundred degrees each day for months on end. Yet he and other biologists have discovered here startling signs of life hidden in plain view under the summer sun: - male digger bees compete to reach virgins underground during the early summer mating season; - the round-tailed ground squirrel goes about its business, sounding alarm calls when danger threatens its kin; - the big-jawed beetles Dendrobias mandibularis emerge in time to feast on saguaro fruits and to use their mandibles on rival males as well; - Harris's hawks congregate in groups, showing their affinity for polyandry and communal hunting; - robberflies mimic the appearance of the bees and wasps on which they prey; - and peccaries reveal the adaptation of their reproductive cycle to the desert's seasonal rains. The book's 38 chapters introduce readers to these and other desert animals and plants, tracing the course of the season through activities as vibrant as mating rituals and as subtle as the gradual deterioration of a fallen saguaro cactus. Enhanced by the line drawings of Marilyn Hoff Stewart, Sonoran Desert Summer is both an account of how modernbiology operates and a celebration of the beauty and diversity that can be found in even the most unpromising places.…

Paperback. Condizione: Very Good. Looks at how sociobiologists study behavior in all species. This work provides an analysis of case histories that involve such topics as sexual jealousy, beauty, gender difference, parent-offspring relations, and rape. It shows that sociobiology provides satisfactory evolutionary analysis of social behavior.…

Paperback. Condizione: Good. This anthology contains 34 articles published since 1977 in American Scientist, the journal of the scientific society Sigma Xi. Articles illustrate how behaviourists think about and conduct their research, and provide greater insight into the behaviour of selected vertebrate and invertebrate species than most textbook accounts. While sequenced particularly to complement John Alcock's Animal Behavior: An Evolutionary Approach, this readily comprehensible and richly illustrated reader will enhance courses based on other textbooks as well. Indeed, the book can stand alone as a sampler of the excitement and diversity of research approaches and organisms that constitute the modern study of animal behaviour.…

Hardback. Condizione: Very Good. It is distinguished by its balanced treatment of both the underlying mechanisms and evolutionary causes of behaviour, and stresses the utility of evolutionary theory in unifying the different behavioural disciplines. Important concepts are explained by reference to key illustrative studies, which are described in sufficient detail to help students appreciate the role of the scientific process in producing research discoveries. Examples are drawn evenly from studies of invertebrates and vertebrates, and are supported by nearly 1300 reference citations. The writing style is clear: beginning students should have no difficulty following the material, despite the strong conceptual orientation of the text.…
