“…Despite for manganese, the activity of the CarE and GST was negatively correlated with metal content in workers ( Table 2). Metals can inhibit the GST non-competitively, but may be activated by organic compounds, thus explaining higher activity in ants from more polluted sites as it was also depicted for spiders collected from Upper Silesia [38]. A tendency to the increase of CarE with the intensity of stressing factors (metals) in the food was confirmed for the Finnish ants, both in pupae and workers [20].…”

“…A tendency to the increase of CarE with the intensity of stressing factors (metals) in the food was confirmed for the Finnish ants, both in pupae and workers [20]. Such compensatory mechanisms were not stated in other species of insects recently studied [3] but was also shown in web spinning spiders [38]. Increased level of herbivorous prey containing phenol compounds may also induce the activity of CarE both in spiders and in ants.…”

Relations between metal contaminations in social groups of ants from colonies of Formica polyctena, from 5 localities variously contaminated by industrial pollution, and their metabolic and detoxifying strategies have been investigated. Cd, Pb, Zn, Mn, Cu levels have been measured in social groups of workers and pupae throughout the season. Patterns of metabolic, transport and detoxifying enzymes have been assayed and phosphoadenine nucleotides and the energy charge (AEC) have been determined. The metal content is a measure of the level of contamination and has been the highest in foragers returning to the nest. Body burdens of Cd, Pb and Zn diminished progressively from the surface workers to those from the inner part of the hill. The concentration of total adenylates was slightly lower than stated in Finnish ants poisoned with Cd, but the AEC index was always above 0.8, with high variations between the social groups. Carboxylesterases showed a positive correlation of activity pattern with the metal load in foraging workers, with the highest value for cadmium load in ants from a locality in the middle of a pollution gradient. The pattern of superoxide dismutase activity has been site-dependent, but it did not correlate well with the metal load in workers.

“…Wolf spiders accumulate more heavy metals in their systems than do other ground-dwelling spider species because of their frequent hunting activities (Marczyk et al 1993;Rabitsch 1995;Wilczek and Migula 1996;Wilczek and Babczynska 2000). Previous laboratory (Jung et al 2005) and field (Jung et al 2007(Jung et al , 2008 experiments have suggested that the wolf spider, Pardosa astrigera L. Koch, is a potential bioaccumulator of heavy metals.…”

Previous studies have proposed that Pardosa astrigera L. Koch (Lycosidae) can be used as a biological indicator of heavy metal contamination in soil. In this study, we estimated the bioaccumulation levels and the bioconcentration factors (BCF) of four heavy metals (Cd, Cu, Pb, and Zn) in adult female P. astrigera collected from various field sites according to heavy metal content gradient and broods. The relationship between heavy metal content in the soil and that in spiders was different depending on the heavy metals and the broods. However, heavy metal content in P. astrigera increased with increasing heavy metal content in the soil. While the heavy metal content in the soil was in the order of Zn > Pb > Cu > Cd, its content in P. astrigera was in the order Zn > Cu > Cd > Pb. The BCF for Cd in both of the broods was distinctly higher than those of the other heavy metals evaluated. These results indicate that P. astrigera may be useful as a biological indicator of Cd soil contamination.

Effects and consequences of stress exposure on life history strategies and quantitative genetic variation in wild populations remain poorly understood. We here study whether long‐term exposure to heavy metal pollution may result in alternative life history strategies and alter quantitative genetic properties in natural populations of the wolf spider Pirata piraticus. Offspring originating from a reference and a metal contaminated population and their reciprocal hybrid cross were bred in a half‐sib mating scheme and subsequently reared in cadmium contaminated vs. clean environment. Results from this experiment provided evidence for a genetically based reduced growth rate and increased egg size in the contaminated population. Growth rate reduction in response to cadmium contamination was only observed for the reference population. Animal model analysis revealed that heritability for growth rate was large for the reference population under reference conditions, but much lower under metal stressed conditions, caused by a strong decrease in additive genetic variance. Heritability for growth of the metal contaminated population was very low, even under reference conditions. Initial size of the offspring was primarily determined by maternal effects, whereas egg size produced by the offspring was determined by both sire and dam effects, indicating that egg size determination is under control of the female genotype. In conclusion, these results show that metal stress can not only affect life history variation in natural populations, but also decreases the expression as well as the of the amount of genetic variation for particular life history traits.
