Regularities 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 کاملAnalysing Syntactic Regularities and Irregularities in SNOMED-CT
MOTIVATION In this paper we demonstrate the usage of RIO; a framework for detecting syntactic regularities using cluster analysis of the entities in the signature of an ontology. Quality assurance in ontologies is vital for their use in real applications, as well as a complex and difficult task. It is also important to have such methods and tools when the ontology lacks documentation and the us...
متن کاملPermanence 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 کاملEvolution of periodicity in periodical cicadas
Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average tempera...
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...
