...Maria E. Giannakou; Julian A. T. Dow SUMMARY The NHE family of Na + /H + exchangers is believed to play an essential role in animals, but may play an additional, specialised epithelial role in insects. The pharmacological sensitivity of the Drosophila melanogaster Malpighian tubule to a range...

... of Drosophila melanogaster that have been selected to survive and develop in food containing 300mmoll −1 urea. Previous research has demonstrated that the urea-selected larvae have lower levels of urea in their body than control larvae reared under the same conditions. The current series of experiments focuses...

... to the protection afforded by rapid cold-hardening. During the cooling phase of a single ecologically based thermoperiod, the tolerance of Drosophila melanogaster to 1 h at −7 °C increased from 5±5 % survival to 62.5±7.3 % (means ± S.E.M., N =40–60), while their critical thermal minima ( CT min ) decreased by 1.9...

...Michael H. Dickinson; Karl G. Götz ABSTRACT We have used flow visualizations and instantaneous force measurements of tethered fruit flies ( Drosophila melanogaster ) to study the dynamics of force generation during flight. During each complete stroke cycle, the flies generate one single vortex loop...

...Michael J. O’Donnell; Simon H. P. Maddrell ABSTRACT The properties of the Malpighian tubules of Drosophila melanogaster change along their length. The upstream main segments secrete K + -rich fluid at a high rate. From this, the lower tubules reabsorb significant amounts of water and K + . Under...
