What is Energy budgets for populations of long-lived arthropod predators (Chilopoda: Lithobiidae) in an old beech forest about?

Energy budgets are derived for two chilopod populations-Lithobius mutabilis L. Koch and L. curtipes C.L. Koch (Chilopoda, Lithobiidae)-in a 125-year-old beech stand in the Solling, Northern West Germany. Lithobiids were sampled from February 1972 to July 1975 by monthly quadrat samples (12 samples of 625 cm each) which were extracted in an apparatus slightly modified after Kempson (Kempson et al. 1963; Weidemann 1971). Regression equations are set up relating fresh weight to width of the cephalic shield and dry weight to fresh weight. The calorific content is estimated by use of literature data. Oxygen consumption is estimated from laboratory measurements in a Warburg apparatus. The values have been corrected for temperature fluctuations in the field and should be increased by a factor of about 1.75 to account for the higher activity of lithobiids in the field. Energy balances for average individuals of L. mutabilis and L. curtipes are presented. An average individual of L. mutabilis produces in the course of its life about 0.42 kJ, respires 0.92 kJ (laboratory value) or 1.6 kJ when increased activity in the field (f.a.) is taken into account. An average individual of L. curtipes p
