Basics of Ecology: Populations: Biotic Potential, Environmental Resistance DVD

Item # 491216 Online Only

DVD looks at how population growth rates are calculated and introduces biotic potential, exponential growth, and environmental resistance before looking at boom-and-bust cycles and carrying capacity of ecosystems. Density-independent limits to population growth, such as changes in the weather, as well as density-dependent limits, such as predation, parasitism, and competition, are then examined. Discussion of distribution of populations over space and time concludes the program.
