Document Summary
Model of population growth with overlapping generations: parents and offspring alive at the same time, most plant and animal species have overlapping generations. Tophat qestion: the per-capita population growth rate, dn/ndt, is the rate at which additional individuals are being added to the population given the number of individuals already in the population. Tophat question: we are studying a population of a threatened weasel species. No weasels survive to reach 4 years of age. Newborn weasels have only a 5% chance of surviving to their first birthday. One-year-old weasels have a 60% chance of surviving to two years of age, and two-year-old weasels have a 90% chance of surviving to three years of age. Female two-year-old weasels each produce 3 female offspring, and female three-year-old weasels each produce 6 female offspring. Tophat question: the population growth rate, dn/dt, is the rate at which additional individuals are being added to the population.
