“…After mixing, the soil was kept in closed plastic containers at 203C. At the start of exposure, any evaporated water was replaced, and the moist soil was placed in &&microcosms,'' as described by Hamers and Krogh (1997).…”

“…This may be the main explanation for the increase in N in H. aculeifer tissues at 100 mg Cd kg À1 . Several comparable studies also show that a high concentration of the insecticide dimethoate dramatically increased the rate of capture of F. candida by H. aculeifer, likely by suppressing the evasive behavior of F. candida (Hamers and Krogh, 1997;Baatrup et al, 2005). Moreover, though the highest atom% (3.35 ± 0.13) of F. candida tissues was lower than that (5.5) of its food wheat, the atom% value in F. candida clearly showed that N of wheat has been largely absorbed by collembolans and could satisfy our need to reflect N transfer in the model food chain from wheat.…”

“…Clearly, with increasing soil Cd concentration the mass mortality of the prey collembolan would indirectly bring about the death of the predator mite. A study of two-species toxicity test systems also suggests that a decrease in the availability of prey can make an important contribution to the decline in H. aculeifer reproduction under exposure to high concentrations of the insecticide dimethoate (Hamers and Krogh, 1997). Cadmium would exert more toxicity to higher trophic levels through predator-prey interactions (Fig.…”

“…However, only a few studies have been reported in which pollutants influenced population variation (e.g. reproduction and survival) in the collembolan-predatory mite food chain (Hamers and Krogh, 1997;Schnug et al, 2014) in stark contrast to the large number of snail food chain studies (Scheifler et al, 2002;Gimbert et al, 2008;Li et al, 2015). So far, no experiment has quantitatively investigated Cd transfer and its effects on the collembolan-predatory mite food chain, especially effects on high trophic level predatory mites.…”

a b s t r a c tEffects of cadmium (Cd) on collembolans and predatory mites have been well studied but Cd accumulation and biological transfer and the relationship between Cd trophic transfer and nitrogen (N) isotope fractionation and transfer in soil micro-arthropod food chains remain poorly understood. Here, we investigated the biological transfer and trophic toxicity of Cd and the effects of dietary Cd exposure on 15 N fractionation in animal tissues and N transfer from food in a soil collembolan (Folsomia candida)-predatory mite (Hypoaspis aculeifer) food chain using experiments conducted in plate and soil systems. Synchronized F. candida were fed yeast or wheat spiked with 0 (Control), 50 (Cd50), 100 (Cd100) or 200 (Cd200) mg Cd g À1 food for two weeks and were then offered to synchronized H. aculeifer as prey for two weeks. Cadmium concentrations in tissues of both the collembolan and its predator increased as the Cd concentrations in the food yeast or wheat increased in both the plate and soil systems, and the Cd concentrations in the food and the animals were all significantly and positively correlated. Except for the controls, the Cd bioaccumulation factor (BAF) between adults of predatory mites and consumer collembolans (0.20e1.13) was 2.5e14 times higher than that from food yeast/wheat to consumer collembolans (0.02e0.08). Cadmium transfer has not altered the reproduction of the filial generation collembolans but the reproduction of the predatory mite declined by 34.3% with the Cd concentration in its juveniles reaching 5.94 mg g N isotope application may be limited in Cd polluted soil ecosystems, and the N transfer function of soil food webs may be more vulnerable in polluted ecosystems.
