Abstract:
... Effects 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 exposur ...

Abstract:
... Effects of cadmium (Cd) on predator-prey relationships and soil ecological function are poorly understood and there are few methods available to measure soil functional change. Thus, we structured a soil-dwelling food chain containing the predatory mite Hypoaspis aculeifer and its collembolan prey Folsomia candida to study the effects of Cd exposure for eight weeks in a spiked soil aged for five y ...

Abstract:
... Highly precise and reliable determination of heavy metals in soil micro-arthropod tissues remains a challenge because of the small size of the animals and their typical low abundance in metal-contaminated agricultural soils. The present study sought to develop a method for cadmium (Cd) determination in soil micro-arthropods by optimizing the sample digestion procedure, reducing sample weight, modi ...

Abstract:
... Effects of microplastics on aquatic organisms have been widely studied in recent years but effects on soil biota, and especially on the gut microbiota of soil animals, remain poorly understood. An experiment was therefore conducted using the common soil collembolan Folsomia candida exposed to microplastics for 56 days to investigate the effects of plastics on gut microbiota, growth, reproduction a ...

Abstract:
... Gut microbiota make an important contribution to host health but the effects of environmental pressures on the gut microbiota of soil fauna are largely uncharacterized. Here, we examine the effects of norfloxacin and oxytetracycline on the gut microbiome of the common soil collembolan Folsomia candida and concomitant changes in the incidence of antibiotic resistance genes (ARGs) in the gut and in ...

Abstract:
... Although the roles of earthworms and soil collembolans in the transport of microplastics have been studied previously, the effects of the soil biota at different trophic levels and interspecific relationships remain poorly understood. Here, we examine three soil microarthropod species to explore their effects on the transport of microplastics. The selected Folsomia candida and Hypoaspis aculeifer ...

Abstract:
... Gut microbiota contribute to host health. Numerous recent studies have focused on the survival and reproduction of nontarget soil animals exposed to the toxicity of silver nanoparticles (AgNPs) but changes in the gut microbiota due to nanoparticle toxicity are largely unknown. Here, we examine some effects of AgNPs and silver nitrate (ionic Ag) on the gut microbiota of the common soil collembolan ...

Abstract:
... Most ectotherms follow the temperature‐size rule (TSR): in cold environments individuals grow slowly but reach a large asymptotic length. Intraspecific competition can induce plastic changes of growth rate and asymptotic length and competition may itself be modulated by temperature. Our aim was to disentangle the joint effects of temperature and intraspecific competition on growth rate and asympto ...
