Population
A group of individuals of the same species occupying a given area
Can be described by demographics (size, density, etc)
Demography
Populations can be described by them (size, density, distribution, and age structure)
Exonential Growth
Population expands by ever increasing increments during successive intervals
Equation= G=rN
Logistic Growth
Growth that occurs where there are limited environmental resources

Equation = G=rN (K-N/K)
Carrying Capacity
The maximum # of individuals that a habitat can sustain (no degradation of the habitat)
Symbol= K
Not constant, it will change over time and space
Limiting Factor
Any essential resource that is in short supply
All limiting factors acting on a population dictate sustainable population size
Density Dependent
Causes changes in birth and death rates as population increases

Resource limitation in populations can: reduce reproduction, increase competition
Density Independent
Don't get smaller in density as population increases
