Population
- A population is a group of individuals from one species living in a given area.
- Mortality is the number of deaths per a given population or standardized population size. A survivorship curve represents how the mortality of the species varies with age.
- Biotic potential is the maximum rate at which a given population could grow under ideal conditions. Exponential growth is the type of growth a population experiences under ideal conditions.
- Carrying
Capacity (K) is the maximum number of individuals that can occupy an
area under given conditions. The logistic model shows growth rate
from the time a population is introduced to an area to the time it
reaches its carrying capacity.
Growth Rate = r N (1 N / K)
- r- selected species have rapid population growth when obstacles are limited. They quickly reach carrying capacity. K-selected species tend to dominate in stable, established environments.
