摘　　要：Genetic diversity in natural populations has been explored through evolutionary analysis,and patterns of microscale biodiversity have been studied in populations at“Evolution Canyon”,Israel.A total of 2,000 eggs from each of iso-female Drosophila melanogaster line 2-1 from the north-facing slope(NFS)and line 6-1 from the south-facing slope(SFS)were placed in 20 vials and evaluated.Egg-to-adult viability was 0.89 and 0.75 in lines 2-1 and 6-1,respectively,and the difference was statistically significant by t-test.Genetic diversity was higher on the harsher SFS than on the milder NFS.Inter-slope genetic differences corroborated the effect of stochastic climate selection pressures to viability polygenes in populations at“Evolution Canyon”,Israel.
