Oviposition preferences for ethanol depend on spatial arrangement and differ dramatically among closely related Drosophila species
Recent work on the model fly Drosophila melanogaster has reported inconsistencies in their preference for laying eggs on intermediate concentrations of ethanol. In this study, we resolve this discrepancy by showing that this species strongly prefers ovipositing on ethanol when it is close to a non-ethanol substrate, but strongly avoids ethanol when options are farther apart. We also show fluidi...
متن کاملGenetic basis of hybrid male sterility among three closely related species of Drosophila.
The genetic basis of hybrid male sterility among three closely related species, Drosophila bipectinata, D. parabipectinata and D. malerkotliana has been investigated by using backcross analysis methods. The role of Y chromosome, major hybrid sterility (MHS) genes (genetic factors) and cytoplasm (non-genetic factor) have been studied in the hybrids of these three species. In the species pair, bi...
متن کاملDNA sequence comparison among closely related Drosophila species in the mulleri complex.
DNA hybridization was used to establish DNA sequence relationships among seven Drosophila species. Single-copy DNA was isolated from four species within the Drosophila mulleri complex, D. mojavensis, D. arizonensis, D. ritae and D. starmeri. These single-copy DNAs were used as tracers to be hybridized with each other and one additional member of the mulleri complex, D. aldrichi, a member of a c...
متن کاملClimate-induced range overlap among closely related species
Contemporary climate change is causing large shifts in biotic distributions1, which has the potential to bring previously isolated, closely related species into contact2. This has led to concern that hybridization and competition could threaten species persistence3. Here, we use bioclimatic models to show that future range overlap by the end of the century is predicted for only 6.4% of isolated...
متن کاملIntracellular targeting of telomeric retrotransposon Gag proteins of distantly related Drosophila species.
The retrotransposons that maintain telomeres in Drosophila melanogaster have unique features that are shared across all Drosophila species but are not found in other retrotransposons. Comparative analysis of these features provides insight into their importance for telomere maintenance in Drosophila. Gag proteins encoded by HeT-A(mel) and TART(mel) are efficiently and cooperatively targeted to ...
