- Meaning of Population Studies
- Factors Affecting Population Growth
- Problems Associated with Human Overpopulation
Population studies encompass the study of population dynamics, how and why population changes over time as well as their interaction with the environment. Parameters of a population include dominance, size, distribution, densityDensity is the measurement of how tightly a material is packed together i.e. how closely the particles are packed in the material. The tighter the material is packed the more its... More, frequency and percentage cover.
- Size: Population size gives an indication of how the population of an organism is surviving in a habitat.
- Dominance: This refers to the population with the largest size in a community.
- Distribution: This refers to the pattern in which the population of organisms are dispersed in a habitat.
- Frequency: Population frequency is defined as the number of times an organism occurs within a given area in its habitat.
- Percentage Cover: This is the area of ground covered or occupied by a given species in its habitat.
- Density: Population density is the average number of individuals of a given species per unit area of the habitat, it can be used to determine the population of an organism.
Density × Area of Habitat = Population Size
