Competition studies inDrosophila: Relative fitness and adaptedness of six closely related species

  • Published:
Proceedings: Animal Sciences

Abstract

Inter and intra specific competition experiments involving 6 taxonomically closely related forms ofDrosophila have been made. Relative fitness and adaptedness of these forms have shown different levels indicating a lack of correlation between taxonomic proximity and ecological phenotype.
