  • Seed & Fruit Ecology II

    • Seed Dispersal• Seed Pool• Consequences of seed pool

  • Seed Dispersal

    • Leptokurtic curve with low mean and long tail

    • dense stand • edge of forest • wind factors • Seasonal release of seeds

  • Dispersal Curves

  • Dispersal

    edge of forest

  • Dense Stands

  • Seasonal release of seeds

  • Dispersal of Fruit: Experimental

  • Seed Pool• Buffering populations

    from environmental variation

    • Seed dormancy would be opposed if there was no environmental variation

    • Selection for immediate germination

  • Seed pools

    •Effect of community composition

  • Characteristics of seed pool

    • Seed germination • Seed dormancy types • born dormant • enforced by

    season/switched on • breaking dormancy • Seed longevity in pool • Seed senescence in

    pool

  • Seed germination

  • Seed germination

    • requirements • dessication• cold • scarification of seed

    coat • light

  • Consequences of seed pool

    • fate of seeds • delay germination • genetic input of good

    years versus bad years
