“…Similarly, Zidar et al (2019) reported that Porcellio scaber was able to detect and avoid soils spiked with AgNPs (20.4 nm) in all the selected concentrations (100, 500, 1000 and 2000 mg/kg). However, when exposed to CeO 2 NPs (<25 nm), an avoidance response of the isopods was detected for the concentration 1000 mg/kg [27]. As expected, the available results show that the effects of nanomaterials on the avoidance behavior of soil organisms depend on the type of material tested.…”

“…Concerning the application of avoidance assays to assess the effects of other nanomaterials, some results are already published [6,26,27]. Bouguerra et al (2016) observed that E. andrei significantly avoided the soils spiked with 1000 mg/kg TiSiO 4 NPs (<50 nm).…”

“…As expected, the available results show that the effects of nanomaterials on the avoidance behavior of soil organisms depend on the type of material tested. For example, in terms of the chemical identity of different nanomaterials, the published literature shows that AgNPs induce more effects on the behavior of the terrestrial organisms than TiSiO 4 NPs and CeO 2 NPs [6,26,27].…”

“…Avoidance assays provide a rapid and valuable ecotoxicological information about contaminated soils [16,17]. Using these tests, the behavioral effects of nanoparticles such as titanium silicon oxide (TiSiO 4 ), cerium dioxide (CeO 2 ) and silver (Ag) have been demonstrated [6,26,27]. The assays rely on the organisms' ability to actively avoid the contaminated soil by detecting a chemical, using chemoreceptor organs and altering their behavior [20,21].…”

“…The assays rely on the organisms' ability to actively avoid the contaminated soil by detecting a chemical, using chemoreceptor organs and altering their behavior [20,21]. Such a response is considered a highly relevant ecological endpoint, because if the organisms avoid a contaminated soil, the services that they provide will be compromised and the habitat function decreases, negatively impacting on the soil ecosystem and animal communities [6,22,27]. On the other hand, the escape of the organisms to "non-contaminated" soils may allow their survival, continuing their ecological performance.…”

Effects of Amorphous Silica Nanopowders on the Avoidance Behavior of Five Soil Species—A Screening Study

Silica nanoparticles (SiO2NPs) are one of the most used in commercial products and biomedical tools, however, their environmental effects have not been fully described. Although negative effects of SiO2NPs on the behavior of freshwater invertebrates have been reported, the knowledge is limited, especially the effect of nanopowders in terrestrial organisms. Accordingly, the aim of the present study is to understand the effects of SiO2NPs on the avoidance behavior of five soil species, whose niche may differ thus contributing to differential harmful SiO2NPs effects. Hence, avoidance assays testing SiO2NPs concentrations of 0, 10, 100, 250, 500 and 1000 mg/kg were performed with Enchytraeus crypticus, Folsomia candida, Tenebrio molitor, Porcellionides pruinosus and Eisenia fetida. SiO2NPs induced different behavioral effects, depending on the invertebrate ecology/habitat, exposure route and physiology. T. molitor, P. pruinosus and F. candida did not avoid contaminated soil; however, E. crypticus and E. fetida significantly avoided SiO2NPs spiked soil. Since these terrestrial worms (oligochaetes) live mostly burrowed in the soil, this can provide greater opportunity for SiO2NPs’ uptake. On the other hand, the other tested organisms mainly living on the upper part of the soil did not avoid the SiO2NPs spiked soil. The avoidance data obtained here also highlight the need for further studies to understand whether (or not) the detected behavioral responses are linked to either neurotransmission processes or sensorial aspects of the biological models.

Bioaccumulation tests with invertebrates have recently been discussed as a suitable alternative to bioaccumulation tests with metal‐ or metal oxide‐based nanoparticles in fish for regulatory assessment. In the present study, as a first step, we investigated the suitability of three invertebrate species for bioaccumulation tests with nano‐ and microplastics. In a laboratory approach the freshwater bivalve Corbicula fluminea, the freshwater amphipod Hyalella azteca, and the terrestrial isopod Porcellio scaber were exposed to fluorescently labeled nano‐ and microplastics to evaluate their suitability to estimate the bioavailability and bioaccumulation of these test items. No bioaccumulation was observed in H. azteca or P. scaber. In contrast, the measurement of the relative fluorescence of the test items in the soft tissue and the feces of the filter‐feeding bivalve allowed us to derive data that may be useful for the regulatory bioaccumulation assessment of manufactured nano‐ and microplastics. The developed measurement method using fluorescence represents a time‐efficient and cost‐effective analytical method for manufactured nano‐ and microplastics in laboratory studies for regulatory assessment.

Dissecting the costs of a facultative symbiosis in an isopod living with ants

et al. 2022

The balance of costs and benefits is expected to drive facultative associations. Here, we assessed the costs of living in a facultative association, by studying the effect of red wood ants on different fitness correlates of the facultatively associated isopod Porcellio scaber.We demonstrated that P. scaber frequently occurs in and near hostile red wood ant nests and may even outnumber obligate nest associates. However, the facultative association involved different costs for the isopod. We found that the density of the isopod decreases near the nest with higher ant traffic. Individuals in and near the nest were smaller than individuals further away from the nest. Smaller individuals were also found at sites with higher ant traffic. In addition, a higher proportion of wounded individuals was found closer to the nest and with higher ant traffic. We recorded pregnant females and juveniles in the nest suggesting that the life cycle can be completed inside the nests. Lab experiments showed that females died sooner and invested less in reproduction in presence of red wood ants. Although P. scaber rarely provoked a strong aggression response, large numbers of the isopod were carried by the ants as prey to the nest. These preyed isopods were mainly dried out corpses.Our results showed that the ant association involves several costs for a facultative associate.Consequently, red wood ant nests and their surrounding territory may act as an alternative habitat where demographic costs are balanced with stable resource provisioning and protection against enemies.
