“…Early microcosm studies suggested that naphthalene might directly affect microbial populations and activity and alter nitrogen dynamics 6 . By contrast, a recent study showed that naphthalene addition is a feasible method to reduce soil micro-arthropods in the field, with negligible direct effects on soil nematodes, microbial abundance and carbon dynamics 1 . Moreover, the restriction efficiency of naphthalene on soil fauna and its non-target effects vary substantially in the field with variations in climatic conditions and soil types 1,9,12 .…”

“…Soil fauna is recognized as an indispensable component of soil biogeochemical cycling 1 . Numerous studies have demonstrated that soil fauna, such as earthworms, millipedes, springtails and mites, play an important role in accelerating the decomposition of organic matter, transforming nutrients and regulating microbial activities in various ecosystems 2–4 .…”

“…It is challenging to research the effects of soil fauna on soil biogeochemical cycling in situ without affecting non-target species or changing the soil microclimate 1 . In general, physical barrier and chemical inhibition are traditional methods to assess how soil fauna can influence the litter decomposition process.…”

“…The role of soil fauna in soil biogeochemical cycling has also been measured by suppressing certain groups of soil fauna communities through the application of biocides such as nematicides, insecticides and fungicides. Naphthalene, a polycyclic aromatic hydrocarbon (C 10 H 8 ), is often used as a biocide to reduce soil and litter arthropod populations and to determine the role of soil fauna in litter decomposition processes in field experiments 1,6 . This approach showed that soil fauna can significantly improve decomposition rates.…”

Naphthalene has been widely used to study the role of soil fauna, but its potential non-target effects on soil enzyme activity remain unknown in subalpine forests. We added naphthalene for two years and determined the effect of such additions on the abundance of soil fauna and soil enzyme activities (β-glucosidase, cellobiohydrolase, invertase, peroxidase, polyphenol oxidase, N-acetyl-β-D-glucosaminidase, leucine arylamidase, urease, nitrate reductase and nitrite reductase) in a subalpine forest. Naphthalene could efficiently suppress the individual density and population of soil fauna in situ . The individual density and number of groups were decreased by 72.6–84.8% and 15.0–28.0%, respectively. Naphthalene significantly affected the activities of β-glucosidase, cellobiohydrolase, polyphenol oxidase, N-acetyl-β-D-glucosaminidase, leucine arylamidase and nitrite reductase and the activity increased in the first litter peak of naphthalene addition, and decreased at the later. The activities of β-glucosidase, cellobiohydrolase, polyphenol oxidase, peroxidase, N-acetyl-β-D-glucosaminidase, leucine arylamidase and nitrite reductase showed a negative correlation with the soil microbial PLFAs. Conversely, the activities of invertase, urease and nitrate reductase were positively correlated with the soil microbial PLFAs. Our results suggest that naphthalene is an effective method to reduce soil fauna in subalpine forest. The enzyme activity was influenced by soil fauna and microbial PLFAs.

Earthworms modulate carbon and nitrogen cycling in terrestrial ecosystems, but their effect may be compromised by the deposition of pollutants from industrial emissions. However, studies investigating how deposited compounds affect the role of earthworms in carbon cycling such as litter decomposition are lacking, although the interactions of earthworms and deposited compounds are important for understanding the impact of pollutants on ecosystems and the potential of earthworms in bioremediation. We performed a 365‐day in situ litterbag decomposition experiment in a deciduous ( Quercus variabilis ) and coniferous ( Pinus massoniana ) forest in southeast China. We manipulated nitrogen (N), sodium (Na), and polycyclic aromatic hydrocarbons (PAHs) as model compounds during litter decomposition with and without earthworms ( Eisenia fetida ). After one year, N, Na, and PAH all slowed down litter mass loss, with the effects of Na being the strongest. By contrast, E. fetida generally increased litter mass loss, and the positive effects were uniformly maintained irrespective of the type of compounds added. However, the pathways to how earthworms increased litter mass loss varied among the compounds added and the two forests studied. As indicated by structural equation modeling, earthworms mitigated the negative effects of deposited compounds by directly increasing litter mass loss and indirectly increasing soil pH and microbial biomass. Overall, the results indicate that the acceleration of litter mass loss by earthworms is little affected by deposited compounds, and that earthworms have the potential to mitigate negative impacts of pollutants on litter decomposition and ecosystem processes.
