title: [Final thermal preference in parthenogenetic females of Daphnia magna Straus (Crustacea: Cladocera) acclimated to various temperatures].
abstract: The final thermal preference (FTP) range in parthenogenetic females of cladoceran Daphnia magna was assessed by "acute" and "chronic" methods. The first method included 4-month acclimation to different temperatures in the range of 14.2 +/- 0.7 to 27.1 +/- 0.3 degrees C; the "chronic" method was characterized by long-term acclimation to +20 degrees C. Two ranges of FTP were found for D. magna, 13.3-15.4 degrees C and 20.2-26.2 degrees C. The thermal preference ofdaphnids and the temperature of acclimation were correspondingly linearly. The range of FTP was independent of the season. The food-searching activity of D. magna rose in April, when the FTP range increased, and the FTP was less pronounced.
