Document Summary

In multiple choice format, identify the definitions to the following terms: Blow-down zone: trees remain standing but are killed. Primary succession: colonization of habitats devoid life (volcanic rock: facilitation by dwarf lupines on the pumice plain. Agents of change: act on communities across all temporal and spatial scales: affected by frequency and intensity (if it was high freq and high intensity the environment too severe) Succession: directional change in species that occurs over time as a result of abiotic and biotic agents of change. Secondary succession: involves reestablishment of a community in which some, but not all, organisms have been destroyed. occurs after fires, storms, logging, etc. The legacy of the preexisting species and their interactions with colonizing species play larger roles than in primary succession. Pioneer/early successional species: (pioneer or early successional species) tend to be stress-tolerant, and transform the habitat in ways that benefit their growth and that of other species.
