dc.abstract.en The prime objective of the study was to find out whether contamination of food with metals affects body size, energetic reserves and developmental instability in ground beetles (Poecilus cupreus L.: Carabidae). The transfer of Cadmium (Cd) and Zinc (Zn) from medium (nominal concentrations in the medium: 0, 40, 160, 640 or 800 mg kg(-1) for Cd and 0, 400, 1600 or 6400 mg kg(-1) for Zn) to housefly larvae to beetles was also studied. Feeding the beetles throughout their entire lifetime with Cd-contaminated housefly pupae resulted in a significant decrease in body caloric value and the size of the elytrae, tibiae and rear femora. Although body mass also decreased with increasing Cd concentration, this effect was non-significant due to large variance in all treatments. Similar trends were also found in beetles fed pupae contaminated with Zn, but the effect on body mass and caloric value was non-significant. Zn exerted significant effects only on the size of the elytrae, middle and rear tibiae, and front and rear femora. No effect on fluctuating asymmetry (FA) was found in Cd- or Zn-treated beetles. The results indicate that ground beetles exposed to metal-contaminated food have lower amounts of energy available, which may be reflected in lower energetic reserves and changed body growth. However, the metals do not cause developmental instability in the carabids studied, at least not in the first generation. The concentrations of Zn were efficiently regulated in carabids, resulting in only minor differences between the beetles exposed to different Zn treatments. In contrast, Cd accumulated both in the housefly and the beetles, and the concentrations increased significantly with increasing medium contamination level. pl
