Patterns of Dispersion Jordan, Tim and Tom
Three types of Dispersion • Clumped • Uniform • Random Provide insight into social interactions in populations and environmental characteristics at a local level.
Clumped • A clumped dispersion describes a group of like organisms clustered around certain thing(s), such as food and water.
WHY?- Clumped • May be associated with mating behavior • Increase effectiveness of predators (pack animals • Safety in numbers • Aptitude of environment (soil quality)
Uniform • An even dispersion of organisms due to environmental factors.
Why?- Uniform • Antagonistic social interactions: territoriality • Competition for resources • Some plants secrete chemicals that inhibit the germination of nearby plants.
Random • The random dispersion of organisms that it independent of other individual organisms of the same species
Why?-Random • Completely unpredictable dispersion of organisms • Due to absence of strong attractions or repulsions among individuals • i.e. Seeds blown in the wind (Dandelions/Maples)
