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.
