Study Notes
Population Concepts
- Population: A group of organisms of the same species in a specific area.
- Population Size: The total number of individuals within a population.
- Population Density: The concentration of individuals in a population per unit area or volume.
- Population Distribution: The spatial arrangement of individuals within their habitat.
Population Dynamics
- Survivorship Curve: A graph illustrating the number of individuals alive at each age, providing insight into mortality rates at different life stages.
- Immigration: The process where individuals from one population join another population in a different location.
- Emigration: The departure of individuals from a population to reside elsewhere.
- Dispersal: The movement of offspring away from their parents to establish new territories.
- Migration: Seasonal, regular movement of populations or individuals that occurs annually.
Growth Patterns
- Exponential Growth: A growth pattern where the population increases slowly initially, then accelerates as the size expands.
- Logistic Growth: A growth pattern that plateaus as the population approaches its carrying capacity, with growth slowing down significantly.
Carrying Capacity
- Carrying Capacity (K): Denotes the maximum sustainable population size that an ecosystem can support without leading to degradation.
- K-Selected Species: Species that thrive in stable environments, exhibiting population control through density-dependent factors.
- r-Selected Species: Species adapted to unstable environments, characterized by rapid population growth and uncontrolled reproduction.
