Elements of ecology

Meer over het boek

Increased public awareness and concern for the environment make the third edition of Elements of Ecology one of the most timely texts available today. Specifically designed for nonmajors, the text offers close examination and in-depth discussions of natural selection and speciation, the dynamic nature of the ecosystems and the effects of over-exploitation of species, the impact humans have on the population dynamics of wild species, and habitat fragmentation and the fate of small populations. To ensure student awareness of today's environmental problems, the third edition provides up-to-date coverage of oil pollution of our marine environment, nuclear radiation and power plants, acid rain, the Yellowstone National Park fires, groundwater drawdown and pollution, and the consequences of wetland drainage. Elements of Ecology, Third Edition, focuses on ecology as a science, yet provides students with the basic background information they need to appreciate how economic and social issues impact on environmental problems.
