Patterns of microsatellite variation through a transition zone of a chromosomal cline in Drosophila americana
Article Abstract:
Twenty-seven 27 polymorphic microsatellites were used to re-evaluate patterns of genetic differentiation between six Drosophila americana populations sampled through a transition zone of both chromosomal forms in the central US. Results rejected a scenario of two differentiated species forming a hybrid zone in a region of parapatry and indicate that gene flow minimizes genome-wide differentiation associated with the two chromosomal arrangements.

Variable fitness effects of Wolbachia infection in Drosophila melanogaster
Article Abstract:
Wolbachia pipientis infects Drosophila melanogaster populations from all continents, but their persistence in this species occurs despite any strong parasitic effects. The symbiosis between Wolbachia and D. melanogaster is investigated which reveals that Wolbachia infection can have significant survival and fecundity effects.

Mitochondrial genome size variation in New World and Old World populations of Drosophilia melanogaster
Article Abstract:
Drosophila melanogaster originated in Africa, spread to Europe and Asia, and is believed to have colonized the New World in the past few hundred years. Levels of genetic variation are typically reduced in New World populations.
