  1. Pivotal time intervals x are related to the average time of egg deposition. Population sizes were n = 69 (N2) and n = 72 (MY6) until x = 137.5 h and n = 36 (MY6 and N2) thereafter.
  2. x= pivotal age in hours; D= length of age class in hours; l x = age-specific survival probability; m x = age-specific fecundity. ∑m x = total fertility rate (TFR); ∑l x * m x = net reproductive rate (R0).
