Managers are producing another new breeding colony of snuffles with the following age-specific survival rates (sx) and reproduction rates (mx). Calculate the population trajectory and the age distribution of this population for twelve years using the table below. Total population size (Nt) at t=12, equals a. N12=3224 b. N12 = 115 c. N12 = 2014 d. N12 = 100 e. N12 = 1012 Yearly growth rate (lambda) at t=11, equals a. l = 2.10 b. l = 1.65 c. l = 1.14 d. l = 0.98 e. l = 1.59 Age distribution at t=12 equals (p(x) = proportion of each age class) a. p(0) = .57, p(1-2) =.28 , p(5-6) =0.05 b. p(0) = .64, p(1-2) =0 , p(5-6) =0.11 c. p(0) = .57, p(1-2) =0.25 , p(5-6) =0.05 d. p(0) = .26, p(1-2) =0.25 , p(5-6) =0.05 e. p(0) = .64, p(1-2) =.23 , p(5-6) =0.11 This population a. Decreases with time b. Increases exponentially with time c. Increases and then stabilizes (logistic growth) d. Does not change in size with time What type of survivorship curve does it have: a.Type I (convex curve) b. Type II (straight line) c. Type III (concave curve) None of the above By t=12, the population has not yet approached stable age distribution. a.True b.False • Show less
