- Population Ecology
- sampling techniques are used to estimate population size
- The exponantial growth pattern occurs in an ideal, unlimited environment
- J shaped curve
- the phases shown in the sigmoid curve can be explained by relative rates of natality, mortality, immigration and emigration
- s - shaped curve
- natality > mortality - exponential phase
- Natality rate approaches mortality rate - transitional phase
- carrying capacity - plateau phase
- population growth slows as a population reaches the carrying capacity of the environment
