Study Notes
- Population ecology studies how and why the number of individuals in a population changes over time.
- Population density is the number of individuals in a population per unit of habitat area.
- Population size can change due to births, deaths, immigration, and emigration.
- Birth rate and death rate are measured per 1,000 individuals in a population in a given year.
- Immigration is the movement of individuals into a population, while emigration is the movement of individuals out of a population.
- Factors that influence population growth include migration, birth rate, and death rate.
- Environmental resistance limits the growth of a population.
- Carrying capacity is the number of individuals of a given species that can be sustained in a given area.
- Overpopulation occurs when the population grows beyond carrying capacity, leading to environmental unsustainability.
- Urbanization is the movement of people from rural areas into towns and cities, and it has both positive and negative effects on the environment.
