Question
Veller et al. proposed that the long intervals between these plants’ flowerings evolved by repeated multiplications from a short initial life cycle, explaining the flowering periods’ having only small prime factors. For 10 points each:
[10h] Name these plants in which all members of a species around the world flower simultaneously at long intervals, with one species flowering every 120 years. Ensuing rodent booms often lead to famines and disease outbreaks.
ANSWER: bamboo [or Bambusoideae]
[10e] These North American insects are divided into “broods” in which all individuals in a given area simultaneously emerge from underground in huge numbers every 13 or 17 years.
ANSWER: periodic cicadas [or periodical cicadas; or Magicicada; reject “locusts”]
[10m] The periodic cicadas’ predator satiation relies on the values of this quantity for the cicadas and their predators being coprime so that predators can rarely take advantage of the cicadas’ emergences, as this value for the cicadas is a relatively large prime, 13 or 17.
ANSWER: generation time
