-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...

Periodical cicada nymphs feed underground on root xylem fluids for precisely 13 or 17 years before emerging at any given locality synchronously and in tremendous numbers. Populations throughout the eastern United States are grouped into variously sized, geographically contiguous broods, which are reproductively isolated from each other. Six distinct species represent the 13and 17-year life cycl...

The formalization of time granularity, the study of computational methods to manipulate granularities and their applications have been the subject of much research in the recent years. This paper aims at filling the gap between symbolic representations defined thrugh calendar algebras and mathematical representations defined through periodical sets of instants. Considering a specific calendar a...
