Contains coverage of abiotic factors& — including air, insolation, precipitation, soils, nutrients, ionizing radiation, and fire; energy flow (with increased emphasis on decomposition); nutrient cycling; population ecology; and community ecology. Updates material on applied ecology/human ecology and ecological ethics. |
