  1. Patterns of Dispersion Katy, Makenzie, Amy

  2. Clumped • The most common pattern of dispersion • Individuals are arranged in patches • Reasons: • Abundance of food • Environmental factors that favor growth • Benefits: • Higher number of available mates • More protection from predators • Increased effectiveness for predators that hunt

  3. Uniform • Evenly spaced dispersion of organisms • Not very common in nature • Reasons: • Competition for resources • Social Interaction: territoriality- defense of a bounded physical space against encroachment by other individuals • Examples: • Some plants secret chemicals that inhibit germination of nearby individuals that could compete for resources • Uniform spacing is maintained by aggressive interactions between King Penguins.

  4. Random • Each organism is independent of other organisms • Random patterns not as common as clumped dispersion • Reasons: • Absence of strong attractions or repulsions within a population • Physical or chemical factors of other organisms do not affect the dispersion pattern • Examples: • Plants growing from windblown seeds
