An investigation of the phenomenon of "passive learning," or how people may acquire information from the mass media despite lacking the "saturation effect" that generally makes the study of this phenomenon difficult. Saturation conditions commonly occur because exposure to political programming is virtually universal. With interest controlled, 2 groups (N = 1,000 interview Rs) receiving different media messages are compared over 2 elections, 1977 & 1981 in NJ. Those with no interest in an election, but who lived in a media-rich environment were 40% more likely to have acquired information than their uninterested cohorts living in a media-poor environment. 4 Tables, 1 Appendix, 8 References.

This major reference is an overview of the current state of theoretical ecology through a series of topical entries centered on both ecological and statistical themes. Coverage ranges across scales—from the physiological, to populations, landscapes, and ecosystems. Entries provide an introduction to broad fields such as Applied Ecology, Behavioral Ecology, Computational Ecology, Ecosystem Ecology, Epidemiology and Epidemic Modeling, Population Ecology, Spatial Ecology and Statistics in Ecology. Others provide greater specificity and depth, including discussions on the Allee effect, ordinary differential equations, and ecosystem services. Descriptions of modern statistical and modeling approaches and how they contributed to advances in theoretical ecology are also included. Succinct, uncompromising, and authoritative—a "must have" for those interested in the use of theory in the ecological sciences
