Abstract | Population energy budgets of Burmoniscus ocellatus, Burmoniscus sp. (Philosciidae), Formosillo raffaelei and Orodillo maculatus (Armadillidae), were calculated. Mean population standing stock of the four species ranged from 1.25-13.61 kJ m -2. Mean total isopod biomass at the two sites was 0.85 and 1.85 g m -2. Annual production of the four species varied from 4.24-30.43 kJ m -2 with 5.2-26.4% (energy content) allocated to reproduction. Annual production of the four species combined at the two sites was 23.22 and 50.15 kJ m -2. P/<> -\B ratios varied from 2.24-4.27. Annual population consumption on mixed litter by the four isopod species ranged from 28.4-183.0 kJ m -2. Total annual consumption by all species at the two sites was 233.7 and 360.2 kJ m -2 (1.96 and 2.53% of annual litter fall). Isopod respiratory rates were proportional to body weight, with an exponent ranging from 0.68-0.78 at 23°C. The annual population metabolism of the four species varied from 14.62-86.11 kJ m -2. Total annual isopod metabolism at the two sites was 116.33 and 185.95 kJ m -2. -from Authors |
