| abstract in English: | The aim of our study was to find the effects of prolonged metal contamination on energy expenditure in the forest-living ground beetle Pterostichus oblongopunctatus F. from five sites with different levels of metal pollution. To determine if expected differences in metabolic parameters are genetically based we used laboratory reared F(1) generation. We measured the CO(2) production with the Micro-Oxymax respirometer every 4 hours during 3 days. For statistical analysis we based on the median, maximum, minimum, upper quartile and lower quartile respiration rates. These statistics we treated as indices of the average daily metabolic rate, maximal and basal metabolic rates, activity metabolic rate and standard metabolic rate (SMR), respectively. Male beetles whose parents originated from contaminated sites had higher basal (p = 0.0598), average (p = 0.1031) and standard (p = 0.1555) metabolic rates. No such effects we observed in females' respiration rate. At the same time, in both sexes we found a positive correlation between CO(2) production rate and body mass, and date of imago emergence. Negative correlation we noticed between respiration rate and number of days of acclimation to higher temperature (20 degreesC) after overwintering in 7 degreesC. |
