Review the Following:
2.4 : Biomes, Zonation and Succession
2.4 : Biomes, Zonation and Succession
- Biomes (5 major classes)
- aquatic, forest, grassland, desert, tundra
- know limiting factors, relative productivity and biodiversity
- What three factors govern the distribution of biomes?
- Distinguish zonation from succession
- What factors result in zonation along a gradient?
- Describe pioneer, intermediate and climax communities
- Describe what happens during succession to:
- energy flow
- gross and net productivity
- diversity
- mineral cycling
- Give examples of human activities that can divert the progression of succession (can lead to alternative stable states)
- Describe r- and K-strategist species
- What are their reproductive strategies?
- Which stage of succession are they better adapted?
- Describe and explain the survivorship curves for r- and K-strategists (see p. 164)
