Document Summary
Exponential growth rate for population under ideal conditions. What happens if resources unlimited, no predators. Cohort: group of individuals that are all born at about the same time - tracked from birth. Survivorship curve: plots how many members of cohort remain alive over time, providing until death, mortality studied info on age specific death rates. Type 1 curve: convex -survivorship high until late life. Type 2 - death rates do not vary much with age. Type 3 - concave indicating death rate for a population is a highest early in life. Opportunistic life history: individuals produce as many offspring as possible as quickly as possible. Short generation time and small body size. Equilibrium life theory: parents produce few high quality offspring.
