“…This is in line with early findings which illustrated that total phenols and condensed tannins can degrade rapidly during litter decomposition [48,49]. This phenomenon might occur because decomposition took place in the rainy area of Western China, and the experimental period was characterized by rain and heat synchrony, creating conditions that were conducive to litter decomposition [50,51]. Specifically, in the rainy area of Western China, abundant rainfall provides better soil moisture conditions for a longer period [52,53] and increases the leaching of total phenols and condensed tannins from fresh litter to soil [54].…”

“…Additionally, as the temperature increases (from May to July), the environmental conditions may become more suitable for the soil fauna, which may cause an increase in the relative importance of the soil fauna [46,80]. This also indicated that specialization dynamics are correlated with environmental context [47,50].…”

Soil fauna play a vital role in contributing to the home-field advantage (HFA: litter decomposes faster in its natural habitat than elsewhere) during litter decomposition. Whether the presence of soil fauna affects the HFA of the decomposition of total phenols and condensed tannins, which are important components of litter, has rarely been investigated. In this study, litterbags with different mesh sizes were transplanted reciprocally, 0.04 mm (basically excluding soil fauna) and 3 mm (basically allowing all soil fauna to enter), in Lindera megaphylla and Cryptomeria fortunei forests. The results illustrated that the loss rates of total phenols and condensed tannins reached 64.07% to 84.49% and 69.67% to 88.37%, respectively, after 2 months of decomposition. Moreover, soil fauna positively contributed to the decomposition of condensed tannins in high-quality litter. After 2 months of decomposition, a significantly positive HFA (HFA index: 10.32) was found for total phenol decomposition in the coarse mesh, while a significantly negative HFA (HFA index: −1.81) was observed for condensed tannin decomposition in the fine mesh after 10 months of decomposition. Polyphenol oxidase (PPO) and peroxidase (POD) activities were significantly influenced by litter types. The loss rates of total phenols and condensed tannins were significantly negatively correlated with the initial N content, P content, N/P ratio, and POD activity and were positively related to the initial C content, total phenol content, condensed tannin content, C/P ratio, and C/N ratio. Only the loss of condensed tannins was negatively correlated with PPO activity (after 2 months’ decomposition). However, none of these correlations were observed after 10 months of decomposition. Our study illustrated that (1) soil fauna contributed to the decomposition of total phenols and condensed tannins but were influenced by litter type for condensed tannins. (2) The soil fauna had inconsistent effects on the HFA of total phenols and condensed tannins, possibly due to the combined regulatory effects of environmental context, litter quality, and rapid decomposition rates. In sum, the results indicated that soil fauna played an important role in the decomposition of condensed tannins and total phenols in litter, and additional studies on the effects of soil faunal abundance and class on HFA of condensed tannins and total phenols are needed.

“…Subsequently, the relative abundance of the core microbial community (4) increases, affecting litter decomposition rates and resulting in the HFA. However, it is difficult for microorganisms in P and H pools to spread to unfamiliar environments because of changes in environmental conditions, and even if they do (3,5), they tend to survive for only a short period. Regardless of the location, microorganisms naturally multiply and die (drift).…”

“…Litter is a general term for leaves, twigs, bark, roots, fruits, flowers, seeds, and other materials scattered in soil or rivers through plant growth and metabolism [1]. Litter decomposition plays an important role in maintaining the nutrient cycle of the ecosystem and the dynamic balance of ecosystem functions [2,3]. Large amounts of carbon (C) are stored in litter [4,5].…”

Litter decomposition is a key component of biogeochemical recycling. It is highly sensitive to changes in microbial community assembly. An interesting phenomenon in litter decomposition is the home-field advantage (HFA), where litter decomposes faster in native locations than in foreign sites. However, the role of the HFA in litter decomposition remains controversial. This review examines current evidence relating to the HFA using the leaf economics spectrum theory and the Lotka-Volterra niche competition model and explains its influence on the microbial assembly process. Here, it is proposed that the microbial community assembly could help to explain the HFA at spatiotemporal scales. This review improves understanding of the role of the succession of microbial communities in HFA litter decomposition and in the elemental cycle of forest systems.

“…This adaptation might alter physiological activities, shifts in community composition, evolution, or a combination of these processes (Milcu and Manning, 2011). Evidence showed that all size classes of soil fauna might contribute to difference in mass loss (Li X et al, 2021), and large dissimilarities in soil microbial communities between different habitat conditions might result in stronger difference. However, for certain plant species at a large spatial scale, whether different groups of soil fauna or microbes, as well as other environmental factors, might affect the difference in mass loss in decomposition has remained unknown.…”
