“…In contrast to other heavy metal contaminants, we did not observe clear patterns indicating a higher toxicity of CuO-NPs on DEA in soils with a coarse texture (high sand content) and low OM content as usually reported (Giller et al, 1998; Kuan et al, 2006; Zhang et al, 2016). Several studies report that NP toxicity varies strongly depending on the types of soils tested but the observed patterns associated with soil texture, pH, and OM content differ both in function of the NP tested and between studies (McKee and Filser, 2016).…”

Metal-oxide nanoparticles (NPs) such as copper oxide (CuO) NPs offer promising perspectives for the development of novel agro-chemical formulations of pesticides and fertilizers. However, their potential impact on agro-ecosystem functioning still remains to be investigated. Here, we assessed the impact of CuO-NPs (0.1, 1, and 100 mg/kg dry soil) on soil microbial activities involved in the carbon and nitrogen cycles in five contrasting agricultural soils in a microcosm experiment over 90 days. Additionally, in a pot experiment, we evaluated the influence of plant presence on the toxicity of CuO-NPs on soil microbial activities. CuO-NPs caused significant reductions of the three microbial activities measured (denitrification, nitrification, and soil respiration) at 100 mg/kg dry soil, but the low concentrations (0.1 and 1 mg/kg) had limited effects. We observed that denitrification was the most sensitive microbial activity to CuO-NPs in most soil types, while soil respiration and nitrification were mainly impacted in coarse soils with low organic matter content. Additionally, large decreases in heterotrophic microbial activities were observed in soils planted with wheat, even at 1 mg/kg for soil substrate-induced respiration, indicating that plant presence did not mitigate or compensate CuO-NP toxicity for microorganisms. These two experiments show that CuO-NPs can have detrimental effects on microbial activities in soils with contrasting physicochemical properties and previously exposed to various agricultural practices. Moreover, we observed that the negative effects of CuO-NPs increased over time, indicating that short-term studies (hours, days) may underestimate the risks posed by these contaminants in soils.

“…The microbial biomass, respiration and microbial N and C were only measure at a single time point in the experiment and thus were not used in any further diversity–stability analyses. For practical reasons, we used the qPCR abundance measures as a surrogate for general microbial abundance and functioning as it has been considered to be an indicator of soil microbial biomass and activity (Anderson, ; Tellenbach, Grünig, & Sieber, ; Zhang et al., ).…”

“…Previously it has been shown that the temporal changes in soil microbial community composition are influenced by land management practices (Lauber et al, 2013), and several past studies have assessed the resistance and resilience of microbial communities to soil perturbation (Griffiths & Philippot, 2013;Griffiths et al, 2000;Girvan, Campbell, Killham, Prosser, & Glover, 2005;Wertz et al, 2007;Zhang et al, 2016) . However, the application of diversity-stability analyses, paralleling those developed in long-term plant diversity studies, that links the stability in the net community functioning to the temporal dynamics within the population has never been considered previously in natural soil microbial communities.…”

Linking diversity, synchrony and stability in soil microbial communities

It is becoming well‐established that plant diversity is instrumental in stabilizing the temporal functioning of ecosystems through population dynamics and the so‐called insurance or portfolio effect. However, it remains unclear whether diversity–stability relationships and the role of population dynamics in soil microbial communities parallel those in plant communities. Our study took place in a long‐term land management experiment with and without perturbation to the soil ecosystem by tilling. We assessed the impacts of the soil perturbation on the diversity, synchrony and stability relationships in soil fungal and bacterial communities. We found that the perturbation to the soil ecosystem not only reduced the abundance and richness of the fungal community, but it also reduced the temporal stability in both bacterial and fungal abundance. The fungal community abundance was destabilized by soil tilling due to reduced richness and increased temporal variation in individual taxa. In contrast, soil tilling destabilized the bacterial community abundance by reducing the temporal variation in individual taxa. Both bacterial and fungal community abundances were more temporally variable when taxa fluctuated more synchronously through time. Our results show that land management practices, such as tilling, can destabilize soil microbial abundance by reducing the richness and disrupting the temporal dynamics below‐ground. However, the differences in the mechanisms that underlie the temporal variations in fungal and bacterial net abundances suggest that the mechanisms that drive the stability can differ among guilds of organisms within the same system. The different temporal responses between the fungal and bacterial communities are likely linked to changes in edaphic properties resulting from the physical alteration of the soil structure.

“…The growth of bacteria and fungi (e.g., the ratio of fungi to bacteria) could also be shaped by soil pH, resulting in a shift in C use efficiency and C mineralization (Rousk et al, 2009). For instance, Zhang et al (2016) investigated 24 soil samples in a transect from north to south China and found a positive correlation between the resistance of C mineralization to Cu (100 mg Cu soil kg -1 ) and soil pH (pH ranged from 4.5 to 8.5). Another study also suggested that the effects of particular microbial taxa on multifunctionality resistance could be controlled by altering soil pH (Delgado-Baquerizo et al, 2017).…”
