Permanence induced by life-cycle resonances: the periodical cicada problem.
Periodical cicadas are known for their unusually long life cycle for insects and their prime periodicity of either 13 or 17 years. One of the explanations for the prime periodicity is that the prime periods are selected to prevent cicadas from resonating with predators with submultiple periods. This paper considers this hypothesis by investigating a population model for periodical predator and ...
متن کاملLife Cycle in Periodical Cicadas
-Several lines of evidence suggest that the 13-year life cycle is genetically dominant over the 17-year life cycle in periodical cicadas. They are: (1) 13-year dominance best predicts the decline of 17 -year Brood X, and concomitant increase in Brood XIX in the midwest, following a hypothesized 1868 hybridization with 13-year Brood XIX through assimilation of heterozygotes into Brood XIX; (2) t...
متن کاملRegularities and irregularities in periodical cicada evolution.
Periodical cicadas are one of those creatures that everyone in eastern North America knows, if only periodically. The seemingly magical invasion every 17 or 13 y of millions upon millions of black, red-eyed, vaguely demonic-looking insects that fill the air with their incessant droning is, indeed, not something that one can easily ignore. These insects even inspired Bob Dylan, in his song “Day ...
متن کاملAvian predation pressure as a potential driver of periodical cicada cycle length.
The extraordinarily long life cycles, synchronous emergences at 13- or 17-year intervals, and complex geographic distribution of periodical cicadas (Magicicada spp.) in eastern North America are a long-standing evolutionary enigma. Although a variety of factors, including satiation of aboveground predators and avoidance of interbrood hybridization, have been hypothesized to shape the evolution ...
متن کاملIndependent divergence of 13- and 17-y life cycles among three periodical cicada lineages.
The evolution of 13- and 17-y periodical cicadas (Magicicada) is enigmatic because at any given location, up to three distinct species groups (Decim, Cassini, Decula) with synchronized life cycles are involved. Each species group is divided into one 13- and one 17-y species with the exception of the Decim group, which contains two 13-y species-13-y species are Magicicada tredecim, Magicicada ne...
