Evolution of prolonged development: a life table analysis for periodical cicadas
Georgians can find the answer over the next few weeks by traveling north into the states mountains to witness the emergence of the latest brood of 17-year periodical cicadas
In 2011, periodical cicada
emergences were reported in 19 South Carolina counties.
In the Koenig and Liebhold study trees were not selected because of known cicada outbreaks on their sites but rather because the trees grew within the range of particular periodical cicada
broods, potentially underestimating the effects of cicadas on oak growth.
Considering that oviposition site choice seems suboptimal in these examples, in which there is no offspring dispersal, our results with periodical cicadas
, in which nymphs do appear to disperse, seem even more plausible.
When periodical cicadas
emerge, they do so in enormous numbers--up to 1,500,000 individual insects per acre, weighing over one ton cumulatively.
Brood XIX, a 13-year brood of periodical cicadas
, has the largest distribution of the periodical cicada
broods, being reported from Maryland south to Georgia, westward through Arkansas and easternmost Oklahoma, and north into southern Iowa.
Population responses of Peromyscus leucopus and Blarina brevicauda to emergence of periodical cicada
These periodical cicadas
live in eastern and central North America, where biologists and spring-wedding planners alike keep tabs on the 15 different cohorts, or broods.
All three periodical cicada
species, Magicicada septendecim, M.
emergences were monitored with surveys of locations where the cicadas had been observed in 1987, 1991, 2001, and 2004.
into the edges of deciduous forest fragments is likely a general phenomenon pertaining to most periodical cicada
broods and to most locations.
