"If it were necessary, for some curious legal reason, to draw a clear line between human and nonhuman--for example, if a group of australopithecines were to appear and one had to decide if they were to be protected by Fair Employment Laws or by the ASPCA--I would welcome them as humans if I knew that they were seriously concerned about how to bury their dead." In this witty and wise way, Lawrence Slobodkin takes us on a spirited quest for the multiple meanings of simplicity in all facets of life. Slobodkin begins at the beginning, with a consideration of how simplicity came into play in the development of religious doctrines. He nimbly moves on to the arts--where he ranges freely from dining...
The earth is continuously changing and evolving yet it is unclear how environmental changes will affect us in years to come. What changes are inevitable? What changes, if any, are beneficial? And what can we do as citizens of this planet to protect it and our future generations? Larry Slobodkin, one of the leading pioneers of modern ecology, offers compelling answers to these questions in A Citizen's Guide to Ecology. He provides many insights into ecology and the processes that keep the world functioning. This important guide introduces observations that underlie arguments about all aspects of the natural environment--including both global and local issues. To clarify difficult concepts, Sl...
"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

Nine months after the explosion, a French expedition searching for signs of life discovered a single spider that had crossed to the island on a balloon of silk. Life had returned to Krakatau. Scientists have been studying the island ever since.
For all persons seriously concerned about the destruction of natural environments in the contemporary world, this book presents a comprehensive rationale for preserving wild species and ecosystems. Bryan G. Norton appeals most centrally to "transformative value," the power of human contacts with wild species to transform and uplift the human spirit. Until now species preservationists have found a theoretical basis for their policies in the "demand" value of wild species for fulfilling certain narrowly defined human needs or in controversial and badly understood proposals about the "intrinsic" values of species. This work examines such rationales and diverges from them by pointing to new sour...
Assembled here for the first time in one volume are forty classic papers that have laid the foundations of modern ecology. Whether by posing new problems, demonstrating important effects, or stimulating new research, these papers have made substantial contributions to an understanding of ecological processes, and they continue to influence the field today. The papers span nearly nine decades of ecological research, from 1887 on, and are organized in six sections: foundational papers, theoretical advances, synthetic statements, methodological developments, field studies, and ecological experiments. Selections range from Connell's elegant account of experiments with barnacles to Watt's encyclo...
Ecosystems are incredibly complex, non-linear structures and self-organized entities; they cannot be described by simple models or by statistical approaches. Within each ecosystem are scores of individuals interacting continuously with others and with their biotic and abiotic surroundings, over vast geographic spaces, and over varying time scales as well. To approach the enormity of this complexity, ecologists have developed tools to simplify and aggregate information, and among them is Hierarchy Theory. Instead of analyzing the whole structure to understand the functions of the system, Hierarchy Theory analyzes hierarchical levels only and the interactions between them. It draws upon two di...
Biotic Crises in Ecological and Evolutionary Time emerged from the third Field Museum Spring Systematic Symposium held in May 1980. The symposium attempted to explore the nature and effects of crisis over as wide a range of temporal and spatial scales as possible. To this end, contributions were included from such diverse fields as astronomy, paleobiology, ecology, and anthropology. The kinds of crises considered ranged from events in the cosmological history of the universe all the way to the effects of a single introduced species on a present-day living community. The book begins by providing a definition of ""crisis"" and a general discussion of methods and approaches to the study of crises. The subsequent chapters present studies on topics such as the physical mechanisms underlying the cosmological framework in which life evolved; physical disturbance in the life of plants; the impact of species introductions; and evolutionary aspects of pre- and post-interchange fossil land mammal faunas in South America.
