Population Growth
Exponential GrowthdN/dt = rmaxN
• dN = change in number
• dt = change in time
• rmax = intrinsic growth rate
• N = number of ind.
Population Growth
Logistic GrowthdN/dt = rmaxN (K-N)
K• dN = change in number
• dt = change in time
• rmax = intrinsic growth rate
• N = number of ind.
• K = Carrying Capacity
Life Histories
r selectedLarge number of offspring
No parental care
Small in size
Short lifespan
K selectedSmall number of offspring
Large amounts of parental care
Large in size
Longer lifespan
