Its presentation is laconic--but all the more clear for that unadorned style. Effective, too, is Slobodkin's precept that popular misunderstanding of what ecology involves enables "experts" on ecological problems to gain support for policies that may not be scientifically justified. To aid understanding, he minutely describes how in one ecosystem, a lake, patterns of species interactions and nutrient flows alter during a year, and then extends basic principles thus elucidated to ocean and land. Slobodkin then proceeds to explain the mathematical dynamics of population growth and decline, the concept of ecological niches, and definitions of biodiversity. As these elements come together as influences on global warming and species extinction--the prime worries about ecology as expressed by the public--Slobodkin's sober examination of those two topics offers the empowerment that arises from genuine knowledge about problems. Highly recommended. Ключевые теги: экология
