Population Ecology
Factors that effect growth or decline
Food
Water
Shelter
Predation
Density
Sufficient Amounts of these factors lead to growth in a population
Insufficient amounts of these factors can lead to a decline in a population
Population Growth
Fertility Rates
Amount of individuals being birthed
Fatality Rates
Amount of individuals dying
Immigration and Emigration
Dispersal
Balance between Biotic Potential and Environmental Resistance
Biotic Potential: the maximum, inherent rate of reproduction
(considered fixed only under a given set of conditions).
Environmental Resistance: the totality of factors tending to limit the actual growth of populations
Population Growth Rate
r = (birth rate + immigration rate) - (death rate + emigration rate)
