Temporal and microgeographic variation in allozyme frequencies in a natural population of Drosophila buzzatii.


Temporal variation in allozyme frequencies at six loci was studied by making monthly collections over 4 yr in one population of the cactophilic species Drosophila buzzatii. Ten sites were defined within the study locality, and for all temporal samples, separate collections were made at each of these sites. Population structure over microgeographic space and… (More)
