Temperature preference of Drosophila immigrans and D. virilis: intra- and inter-population genetic variation.

Abstract excerpt

Large amounts of genetic variation for preferred temperature was uncovered in natural populations of Drosophila immigrans and D. virilis. On average, the former preferred 17.8 degrees C and the latter did 21.0 degrees C. Most variation in D. immigrans was found among isofemale lines within geographic populations, with no significant difference among geographic populations. Both intra- and inter-populational...
