D. buzzatii is a cactophilic species associated with several cactaceae in Argentina. This particular ecological niche implies that this species is faced with a non-uniform environment constituted by discrete and ephemeral breeding sites, which are colonized by a finite number of inseminated females.

โฆ Synopsis
The patterns of genetic polymorphism for soluble enzymes are similar in Colorado populations of Drosophilapseudoobscura at 1 800 and 3 500 m above sea level although their chromosomal polymorphisms are very different. Whatever forces of natural selection might affect enzyme variation cannot easily be related to the ecological parameters which change with altitude.
