Table 1. 1975 cohort of the cactus finch (Geospiza scandens). Age Class (x) Number Alive (Nx ) lx dx qx 0 82 1.00 1 42 2 25 3 17 X X 1. Fill in the table above by calculating the following life table values: a. Calculate lx , the proportion of individuals surviving to each age class with respect to the initial number of individuals. [2 points] lx = Nx / N0 (where N0 is the number alive in age class b. Calculate dx , the proportion of individuals dying between age classes x and x + 1. [2 points] dx = lx l x+1 c. Calculate the mortality rate, qx , or the proportion dying as compared to the proportion surviving. [2 points] qx = dx / lx d. What information would you need to fill in the shaded boxes with X s in them? [2 points]
