Özet

Fruit flies (Drosophila metanogaster) were exposed to low temperature (4 degrees C, 3d), after controlled acclimation (15 degrees C, 1d) and passed to artificial hibernation. The concentrations of elements in almost 1000 mature flies were measured by Wavelength-Dispersive X-ray Fluorescence (WDXRF) spectrometry. Concentration changes of Zn, K, S, Ca (33.5%, 11.2%, 10.3% and 7.5%, respectively) and especially Cr and Mn (99.90 and 99.60) were observed. Concentrations of Cr, Zn, S and Ca increased significantly, but concentrations of Mn and K decreased in with comparison to the control group. (c) 2006 Elsevier Ltd. All rights reserved.
