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.

P-elements strengthen reproductive isolation within the Drosophila simulans species complex
Determining mechanisms that underlie reproductive isolation is key to understanding how species boundaries are maintained in nature. Transposable elements (TEs) are ubiquitous across eukaryotic genomes. However, the role of TEs in modulating the strength of reproductive isolation between species is poorly understood. Several species of Drosophila have been found to harbor P-elements (PEs), yet only D. simulans is known to be currently polymorphic for their presence in wild populations. PEs can cause reproductive isolation between PE-containing (P) and PE-lacking (M) lineages of the same species. Here, we use the simulans species complex to assess whether differences in PE status between D. simulans and its sister species, which do not harbor PEs, contribute to multiple barriers to gene flow between species. We show that crosses involving a P-D. simulans father and an M-mother from a sister species exhibit lower F1 female fecundity than crosses involving an M-D. simulans father and an M-sister-species mother. We also find that another TE, I-element, might play a minor role on determining the frequency of dysgenesis between species. Our results suggest that the presence of PEs in a species can strengthen isolation from its sister species, providing evidence that TEs can play a role in isolation. --
