Lead impact on nutrition, energy reserves, respiration and stress protein (hsp 70) level in Porcellio scaber (Isopoda) populations differently preconditioned in their habitats

摘要: The impact of lead on food consumption, energy metabolism and the stress protein (hsp 70) level was investigated in woodlouse Porcellio scaber (Isopoda), a common representative saprophagous soil macrofauna. To examine possible acclimation or tolerance to woodlice from contaminated habitat, animals two populations, one deriving lead-contaminated artillery range an uncontaminated control stand, were exposed series concentrations under otherwise constant laboratory conditions for maximum 80 days. applied (at 7945 mg/kg dry wt) did not have any significant quantitative effect consumption isopods, although population pre-exposed showed tendency toward higher uptake than population. After days exposure, both populations equal trend increasing their respiration as concentrations, that they had been fed on, increased. Accordingly, glycogen content body, elevated with food. This more pronounced isopod stand. non-pre-exposed isopods general lower bodies ones, no this parameter could be statistically proven. ability artillary synthesise proteins response contamination decreased at much population, even though seemed equally slightly better equipped storage products.
