Question
The eigenvector of a Leslie matrix is the stable distribution for this discrete variable 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 variable. Mortality rate increases with this quantity on a type I (“one”) survivorship curve and decreases with it on a type III (“three”) curve. Two (*) vertically stacked histograms—one each for males and females—are plotted base-to-base to show the distribution of this quantity on a demographic pyramid. Fecundity decreases as this quantity goes up due to senescence. For 10 points, what property of an organism is inferred by measuring the length of telomeres or the number of tree rings? ■END■
