This book was released on 2012-12-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exigencies of life in the desert environment have resulted in the se lection of a diversity of adaptations, both morphological and physiologi cal, in the flora and fauna. At the same time, many plants and most small animals are able not merely to exist but even to thrive under desert conditions - mainly by avoiding thermal extremes and by the refine ment of pre-existing abilities to economise in water. In the same way, the biotic interactions of the flora and fauna of the desert do not involve many new principles. Nevertheless, conditions in arid regions frequently do invoke refinements of the complex interrelations between predators and their prey, parasites and their hosts, as well as between herbivores and the plants upon which they feed. In this book, I shall discuss not only such interactions and their feedback effects, but also community processes and population dynamics in the desert. The physical conditions of the desert that principally affect predators and their prey are its openness and the paucity of cover. This is re stricted to scattered plants, occasional rocks, holes, and crevices in the ground. Furthermore, nightfall does not confer relative invisibility, as it does in many other ecobiomes, because of the clarity of the atmosphere. The bright starlight of the desert renders nearby objects visible even to the human eye, while an incandescent moon bathes the empty landscape with a flood of silver light. Consequently, adaptive coloration is func tional at all hours of the day and night.

Download or read book The Future of Arid Lands Revisited written by Charles F. Hutchinson and published by Springer Science & Business Media. This book was released on 2007-12-07 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Future of Arid Lands, edited by Gilbert White and published in 1956, comprised papers delivered at the "International Arid Lands Meetings" held in New Mexico in 1955. At these meetings, experts considered the major issues then confronting the world’s arid lands and developed a research agenda to address these issues. This book reexamines this earlier work and explores changes in the science and management of arid lands over the past 50 years within their historical contexts.

Download or read book Human Ecology as Human Behavior written by John W. Bennett and published by Routledge. This book was released on 2017-07-05 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human interaction with the natural environment has a dual character. By turning increasing quantities of natural substances into physical resources, human beings might be said to have freed themselves from the constraints of low-technology survival pressures. However, the process has generated a new dependence on nature in the form of complex "socionatural systems," as Bennett calls them, in which human society and behavior are so interlocked with the management of the environment that small changes in the systems can lead to disaster. Bennett's essays cover a wide range: from the philosophy of environmentalism to the ecology of economic development; from the human impact on semi-arid lands to the ecology of Japanese forest management. This expanded paperback edition includes a new chapter on the role of anthropology in economic development.Bennett's essays exhibit an underlying pessimism: if human behavior toward the physical environment is the distinctive cause of environmental abuse, then reform of current management practices offers only temporary relief; that is, conservationism, like democracy, must be continually reaffirmed. Clearly presented and free of jargon, Human Ecology as Human Behavior will be of interest to anthropologists, economists, and environmentalists.
