Population Growth Students will be able to: Define emigration and immigration. Differentiate exponential growth from logistic growth. Differentiate density dependent limiting factors from density independent.

Important Characteristics of a Population Geographic distribution Area inhabited by a population Density Growth Rate

Factors that Affect Population Size # of births # of deaths # individuals entering or leaving

Population Density # of individuals per unit area

Movement of Individuals Immigration Movement of individuals into an area Emigration Movement of individuals out of an area

Exponential Growth Occurs when a population has: - Abundant space and food - Protection from predators and disease

Logistic Growth As resources become less available -> growth of a population slows or stops How? Birthrate decreases Death rate increases

Carrying Capacity Largest # of individuals that environment can support

Limiting Factor Factor that causes population growth to decrease

Drought & Other Climate Extremes Density – Independent Density – Dependent Human Disturbances Competition Depend on population size Strong when population is large & dense Affect all populations Regardless of size Population Size Predation Drought & Other Climate Extremes Parasitism & Disease

Clear Cutting Forests Density Independent

Parasitism Density Dependent

Need for Light Density Dependent
