1. POPULATION
Is a group of individuals of the same species that interact with each other in the same place at the same time.
2. DEMOGRAPHY: The study of vital statistics of a population, including birth and death rates, age of first breeding, and fecundity.
3. BIRTH RATE: The average number of births per individual per unit of time.
4. DEATH RATE: The average number of deaths per individual per unit of time.
5. CARRYING CAPACITY (K): is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. The point where the realized growth of a population equals zero due to density-dependent factors that affect birth and death rates.
6. DENSITY : The number of individuals per area within the range of a species.
7. DENSITY- DEPENDENT FACTORS: Factors (e.g., disease, starvation, lack of nesting space) that cause declines in birth rates or increases in death rates due to intraspecific competition with increasing population density.
8. DENSITY-INDEPENDENT FACTORS: Factors (e.g., fires, floods) that cause declines in birth rates or increases in death rates from events unrelated to population density.
9. DISTRIBUTION: Total geographic range of all populations of a species, including gaps between populations.
10. EXPONENTIAL GROWTH: A population growth model where the rate of increase or decrease of a population is unaffected by intra and interspecific competition or other factors affecting growth.
11. GROWTH RATE (r): The mean rate of growth of a population at any given time calculated by birth minus death rates.
12. IMMIGRATION: The movement of new individuals into a population from a different area.
13. INTRINSIC GROWTH RATE: The mean rate of growth of a population calculated by birth minus death rates when the population is free of competition with other species and from other factors that affect growth.
14. LOGISTIC GROWTH: A population growth model where the intrinsic rate of increase of a population slows or decreases to its realized growth rate when it is affected by intraspecific competition and density-dependent factors.
15. META POPULATION: A population of populations, interconnected by immigration, emigration, and gene flow.
16. ALLEE EFFECT: The effect where populations at high or low densities begin to decline from negative growth rates.
17. CLUMPED DISPERSION: Refers to clumps of individuals of the same species scattered throughout the range of that species.
18. RANDOM DISPERSION: Random spacing of individuals of the same species within an area.
19. UNIFORM DISPERSION: Even spacing of individuals of the same species within an area.
20. REALIZED GROWTH RATE: The mean rate of growth of a population at any given time calculated by birth minus death rates when the population is affected by inter and/or intraspecific competition and other factors that affect growth.
21. SINK AREA: A region where a population is in continuous decline and must be supplemented through immigration to sustain itself.
22. SOURCE AREA: A region where a population is in continuous increase and individuals emigrate to new areas.
3. BIRTH RATE: The average number of births per individual per unit of time.
4. DEATH RATE: The average number of deaths per individual per unit of time.
