Population Ecology

Pattern of spacing in a population.

• Spatial dispersion

• Population ranges

• Exponential Growth

• Logistical Growth

Factor that limits a population and is dependent on the number of organisms in the population.

• Density-dependent

• Density-independent

• Abiotic factors

• Biotic factors
