WebbINTRODUCTION. A life table is a record of survival and reproductive rates in a population, broken out by age, size, or developmental stage (e.g., egg, hatchling, juvenile, adult). Ecologists and demographers (scientists who study human population dynamics) have found life tables useful in understanding patterns and causes of mortality ... WebbWe use different equations to calculate continuous growth). To calculate lambda, we use the equation λ = N1/ N0. Here, N stands for the population size. N0 is the population size initially (at time "zero"), while N1 is the population size at a later time (time "1"). λ = N1/ N0. λ = 225/ 150. λ = 1.5.
