Figure. 3 in Niche separation between the cosmopolitan species Drosophila melanogaster and the tropical Asian species Drosophila ananassae based on larval host-plant species
Figure. 3. Statistical interaction between Drosophila species and larval host plant in determining the number of male flies eclosing in the present experiment. Blue circles represent replicates for Drosophila ananassae and Drosophila melanogaster when raised on cucumberfruit (Averrhoa bilimbi). Red circles indicate replicates where D. ananassae or D. melanogaster were raised on banana (Musa sp.). The number of male flies eclosing from each replicate are presented as squareroot transformed data (variable: TFlies), since the transformed data were used in the ANOVA to determine the statistical significance of this statistical interaction. Da. = Drosophila ananassae, Dm.= Drosophila melanogaster.
