“…Thelephorales, belonging to Basidiomycota, constitutes one of the groups of ectomycorrhizal fungi (ECM) that plays a critical role in a number of key ecosystem functions, such as nutrient mobilization from soil organic matter, carbon cycling, and linkages between trees and soil through common mycorrhizal networks [54][55][56]. Similar results were found in a laboratory Petri plate study, wherein naphthalene reduced radial growth in eight out of nine Basidiomycete fungi [57], while another study concerning a secondary fir forest on the eastern Tibetan Plateau, China, showed different results, wherein naphthalene stimulated basidiomycete mycelia; this disparity might have been provoked by the vast environmental differences of the study sites [58]. The translocation of nutrients via mycelial connections at the soil-litter interface is a vital mechanism that controls the decomposition of plant residues [59,60].…”

The soil food web is essential for the functioning of terrestrial ecosystems. The application of naphthalene is a commonly employed experimental treatment for expelling soil fauna to examine faunal effects on litter decomposition processes, for which is it assumed that naphthalene has negligible effects on soil microbial communities. An experiment was conducted to examine the potential soil-fauna-repellent effect of naphthalene application (100 g/m2/month, TR) on a soil fungal community during litter decomposition. The results showed that TR greatly suppressed the abundance and taxonomic richness of soil fauna by 83.7 ± 14.2% and 48.1 ± 17.2%, respectively, and reduced the rates of poplar leaf litter decomposition compared to the control (CK, without naphthalene treatment). Among the fungal communities, the abundance of Thelephorales in the TR soil was suppressed, while the abundance of Capnodiales was stimulated, although TR did not significantly alter the carbon and nitrogen content in the soil microbial biomass nor the diversity of soil fungal communities and the most abundant fungal phylum. Thus, both the suppressed soil arthropod abundance and altered soil fungal community might contribute to the observed slowdown in litter decomposition. These results suggest that naphthalene, as a soil fauna repellent, can alter the abundance of specific taxa in a soil fungal community, thereby impeding the effort to elucidate the contribution of soil fauna to ecosystem functioning (e.g., with respect to litter decomposition).

“…We did not find a significant difference in effects on invertebrate effect sizes between physical and chemical protocols. The potential non‐target effects of chemicals such as naphthalene on soil organisms and environments (Lan et al., 2020), however, leads us to advocate the use of physical exclusion methods (Lan et al., 2019), particularly in highly stochastic tropical rainforests and in regions with high precipitation.…”

Forest litter decomposition is an essential component of global carbon and nutrient turnover. Invertebrates play important roles in litter decomposition, but the regional pattern of their effects is poorly understood. We examined 476 case studies across 93 sites and performed a meta‐analysis to estimate regional effects of invertebrates on forest litter decomposition. We then assessed how invertebrate diversity, climate and soil pH drive regional variations in invertebrate‐mediated decomposition. We found that (1) invertebrate contributions to litter decomposition are 1.4 times higher in tropical and subtropical forests than in forests elsewhere, with an overall contribution of 31% to global forest litter decomposition; and (2) termite diversity, together with warm, humid and acidic environments in the tropics and subtropics are positively associated with forest litter decomposition by invertebrates. Our results demonstrate the significant difference in invertebrate effects on mediating forest litter decomposition among regions. We demonstrate, also, the significance of termites in driving litter mass loss in the tropics and subtropics. These results are particularly pertinent in the tropics and subtropics where climate change and human disturbance threaten invertebrate biodiversity and the ecosystem services it provides.

Our results demonstrate the significant difference in invertebrate effects on mediating forest litter decomposition between the tropics and elsewhere. We demonstrate, also, the significance of termites in driving litter mass loss in the tropics.
