Question

The eigenvector of a Leslie matrix is the stable distribution for this discrete variable (0[1])in a population. Structured population models are classified either by stage or by this variable, which is required to specify a vital birth or death rate. Fisheries measure oto·liths to determine a population’s distribution of this (20[1])variable. (20[1])Mortality rate increases (20[1])with this quantity (20[3]0[1])on a type I (20[2])(“one”) survivorship (0[1])curve (20[2]0[2])and decreases with it (20[1]0[1])on (20[1])a type (20[1])III (20[1]0[1])(“three”) curve. Two (*) vertically (10[1]0[2])stacked histograms—one (0[1])each for males and females—are (0[2])plotted base-to-base to show the distribution (0[1])of this (0[1])quantity on a demographic (10[1]0[1])pyramid. (0[2])Fecundity decreases as this quantity goes up due to senescence. (10[1])For 10 points, what property (0[1])of an organism is inferred by (10[1])measuring the length of telomeres (10[1]0[1])or (10[1])the number (10[1])of tree rings? (10[4])■END■ (10[9])
