The Economy of Nature 6th Edition by Robert E. Ricklefs offers vivid examples fromnatural history, comprehensive coverage of evolution, and quantitative approach. The Sixth Edition builds on the book’s hallmark features: its strong evolutionary focus, its breadth and diverse set of examples, its extensive coverage of behavioral ecology, and a thorough presentation of population ecology.
Author describes the ways in which organisms adapt to their surroundings. Twenty-six chapters discuss such topics as biological communities, nutrient regeneration in terrestrial and aquatic ecosystems, sex and evolution, population growth and regulation, competition, predation, biodiversity, global ecology and economics, extinction, and conservation.
More than 30 case studies found throughout the text describe classic and current field and laboratory research. The text is accompanied by numerous color photographs and illustrations. presents Darwinian evolutionary principles including natural selection, adaptation, and relevant concepts from population genetics. The chapter provides a more focused discussion of evolution by bringing together concepts previously covered separately across several chapters.
Six two-page spreads explore 'global change' resulting from human impact on ecosystems helping students gain an understanding of the relationship between humans and their environment. The new edition includes a number of modern developments in ecology, both technical and conceptual, including applications of stable isotopes and phylogenetics, recent developments in macroecology, neutral theory, metabolic theory, invasion biology, and global processes connected with human activities.
To address an increasing interest in landscape ecology, a new chapter presents key large-scale ecology topics specifically requested by instructors. To help students make a more meaningful connection between adaptations and the physical environment, chapters 2 and 3 have been reconceived as a chapter on adaptations related to water and a chapter on adaptations related to energy and temperature. Ecosystems ecology now follows community ecology, which brings the Table of Contents into closer alignment with the order in which ecology is taught in most courses.
