Introduction to LHE
Triangle of survival, rep. and growth/maintenance
Maximize fitness
Intrinsic factors: birth/death/growth/maturation
Extrinsic factors: food (external) & birth/death/growth/maturation
Intrinsic constraints: how often you can reproduce/how fast after giving birth are you fertile
Extrinsic constraints: ecological constraints (temperature), predation, food availability
Smaller body size = higher fertility rate (off per year)
Bigger body = less babies
Trade off: grow yourself/have offspring
