    • Seed Dispersal Wilkes Community College - BioNetwork
    • Methods of Seed Dispersal
      • Wind
      • Water
      • Animal
      • Self-Dispersal
    • Wind Dispersal
      • Anemochory
      • Wind is the most
      • effective of the dispersal types. When deforestation occurs the plant material that uses this type of dispersal is usually seen first.
    • Water Dispersal
      • Hydrochory
      • The seed in this type of dispersal contains tissue for the seed to be buoyant. Sometimes the seed itself will not float, but the fruit that the seed is enclosed in will.
    • Animal Dispersal
      • Zoochory
      • Divided into three groups:
      • Endozoochory – seeds are eaten and pass through the digestive tract
      • Epizoochory – seeds become attached to animal and become detached later
      • Synzoochory – seeds are collected by animal to be eaten later
    • Self-Dispersal
      • Autochory
      • In this type of dispersal the fruit may explodes releasing the seeds or may contain a trip mechanism that when stimulated release the seeds.
