- Medicine, Geography
- American journal of human genetics
- 1 April 1999
To assess the extent to which the Nile River Valley has been a corridor for human migrations between Egypt and sub-Saharan Africa, we analyzed mtDNA variation in 224 individuals from various… Expand

- C. Simon
- Biology
- 1983
Although members of the Homopteran family Cicadidae are world wide in distribution, only the North American genus Magicicada exhibits a perfectly synchronized life cycle 13 or 17 years long. All but… Expand
A SIMPLE MENDELIAN MODEL FOR 13‐ AND 17‐ YEAR LIFE CYCLES OF PERIODICAL CICADAS, WITH HISTORICAL EVIDENCE OF HYBRIDIZATION BETWEEN THEM

- 1 November 1983
Periodical cicadas (Homoptera: Cicadidae: Magicicada spp.) are found only in the eastern deciduous forest region of the United States and have life cycles of either 13 years (Mississippi Valley and… Expand
Patchiness, Density, and Aggregative Behavior in Sympatric Allochronic Populations of 17‐Year Cicadas
Densities of two allochronic, geographically overlapping populations of periodical cicadas were censused in the eggnest stage in order to test the hypothesis that larger populations can be supported… Expand
MORPHOLOGICAL DIFFERENTIATION IN WING VENATION AMONG BROODS OF 13‐ AND 17‐YEAR PERIODICAL CICADAS
- C. Simon
- Biology, Medicine
- Evolution; international journal of organic…
- 1 January 1983
It has traditionally been assumed that no morphological differences exist between the 13and 17-year life cycle forms of the periodical cicadas. Thus, differences among year-classes (broods) within a… Expand
