Populations in Ecosystems: Conservation

• Organisms can modify their abiotic environment, resulting in a less hostile environment and altered biodiversity. • Conservation often involves managing succession in habitats. • Students need to understand the conflict between human needs and conservation for preserving natural resources. • They should evaluate evidence regarding conservation of species and habitats, and deal with conflicting evidence. • Students should be able to use given data to estimate population size using the mark-release-recapture method. • Specific examples of local, national, and global conservation programs should be known. • Mind maps are recommended for revising and remembering these concepts.
