Abstract
The prediction of a niche-width variation hypothesis was tested on O. noemi (Coleopterea, Scarabeidae) from microclimatically contrasting slopes at a Mediterranean microsite, at Nahal Oren, Mount Carmel, Israel. A total of 88 individuals of O. noemi were examined, 51 individuals from the S-slope, 16 individuals from the N-slope, and 21 individuals from the bottom (B) of the canyon, each tested from 22 putative allozyme loci. Genetic diversity indices A, P, and He were higher on the S-slope as compared to the N-slope, as predicted, and H was the same on both slopes. It is believed that the results in O. noemi and in other invertebrates support the niche width genetic variation hypothesis, or more generally, the environmental theory of genetic diversity. -from Authors
