Population Ecology
biotic/abiotic ecosystems
pop size
pop density
pop distribution
-uniform, clumped, random
age structure diagrams
birth/death survivorship curves
One other curve: Deer (type IV)

logistic growth S curve
r type organisms: Nemo (manu offspring, short lifespans)
K type organisms: humans, elephants, whales (few offspring, long lifespans)
density dependent factor-rats, food
density independent: disasters
biotic potential-fertility, gestation time
