Genetically idiosyncratic responses of Drosophila melanogaster populations to selection for improved learning ability

Kawecki, Tadeusz J. ; Mery, Frederic

In: Journal of Evolutionary Biology, 2006, vol. 19, no. 4, p. 1265-1274

To what extent is adaptive evolution over short timescales repeatable? To address this question, we studied the performance of crosses between replicate Drosophila melanogaster lines previously subject to selection for improved learning response in the context of oviposition substrate choice. Of the 10 pairwise F1 crosses among the five selection lines, four performed in the original learning...

Reduced learning ability as a consequence of evolutionary adaptation to nutritional stress in Drosophila melanogaster

Abstract. 1. Dietary conditions affect cognitive abilities of many species, but it is unclear to what extent this physiological effect translates into an evolutionary relationship.2. A reduction of competitive ability under nutritional stress has been reported as a correlated response to selection for learning ability in Drosophila melanogaster. Here we test whether the reverse holds as well,...
