demography
study of population processes, recognizes individuals
population dynamics

age structure
distribution of individuals across age
dispersion

type 1
high survivor through adulthood
type 2
constant risk of immortality
type 3
low juvenile survivorship
biotic potential
all populations have the potential for explosive growth
population density dependent factors
competition, predation, parasites
population independent factors
wildfires, freezes, drought
fecundity
unpredictable habitats are associated with high fecundity, as organisms make the most of rare opportunities to reproduce, predictable habitats have low fecundity and low r
r-strategists
life history that allow for high intrinsic rates of increase, type 3
k-strategists
allow them to persists at or near k, type 1 and 2
