Science
Population dynamics.
Definition
Population dynamics is the study of how and why populations change in size and structure over time. It examines factors like birth rates, death rates, immigration, and emigration that cause populations to grow, shrink, or stabilize.
Examples
Real-world.
- 1 Deer populations rising when wolves are removed from an area
- 2 Algal blooms occurring when nutrient runoff increases reproduction rates
- 3 Seasonal fluctuations in mosquito populations based on temperature and rainfall
Key Fact
Population change = (births + immigration) − (deaths + emigration)
