“…In general, multitudinous kinds of plant litter can promote the diversity of soil mesofauna. In addition, some previous studies have demonstrated that mixed species can promote the rates of plant litter decomposition and nutrient release, which creates good soil conditions, and thus many more taxa of soil mesofauna are attracted there to colonize [23]. Therefore, the MU treatment exhibited the greatest richness and diversity of soil mesofauna in the alpine tundra of the Changbai Mountains.…”

Deyeuxia purpurea, a low-altitude species, has been expanding upwards into alpine tundra, and this upward expansion is causing serious ecological consequences. However, few studies have been performed regarding its effects on soil faunal communities. We examine how the upward expansion of D. purpurea affects the abundance, richness, and diversity of soil mesofauna, and evaluate how different taxa of soil mesofauna respond to the upward expansion of D. purpurea in the alpine tundra of Changbai Mountains, northeast China. A total of 128 soil mesofaunal samples were collected from four treatments, namely high upward expansion (HU), medium upward expansion (MU), low upward expansion (LU), and native plant habitats (NP). The results revealed that the abundance of soil mesofauna was increased with the rise of D. purpurea upward expansion, and the taxonomic composition varied with the different levels of D. purpurea upward expansion in the alpine tundra of the Changbai Mountains. No unique taxa were collected in the native plant habitats, and the upward expansion of D. purpurea promoted the colonization of predatory invertebrates. Isotomidae and Gamasida responded positively to the herbaceous plant upward expansion, and thus they were considered to be a positive indicator of upward expansion. Hypogastruridae and Enchytraeidae responded relatively negatively, while Oribatida, Actinedida, and Pseudachorutidae had ambivalent responses to the upward expansion. Overall, the abundance of soil mesofauna can indicate the levels of the upward expansion of D. purpurea. Soil mesofaunal guild characteristics were altered by the upward expansion. The different taxa of soil mesofauna responded to herbaceous plants’ upward expansion to various degrees. Therefore, this study provide evidence supporting the fact that the abundance of soil mesofauna can indicate the levels of upward expansion of D. purpurea, but the responses of soil mesofauna to the upward expansion of D. purpurea differ among their taxa.

“…The role of litter fauna on litter mass loss is dependent on litter composition (AUGUSTO et al, 2014). Low-quality litter can show significantly lower fauna effects in the decomposition process (LI et al, 2015a). Pine species including P. taeda are recognized as low quality showing slow decomposition rates, which depends on climatic conditions and its effects on microbial growth rate (OLSSON et al, 2019).…”

A produção de serapilheira e sua decomposição desempenham um papel importante no ciclo do carbono terrestre e na qualidade do solo, sendo um processo crucial envolvido na produtividade e funcionamento do ecossistema. Compreender esse processo em áreas comerciais de pinus ou invasões de pinus é crucial para projetar o manejo florestal ou a restauração de ecossistemas. Conduzimos um estudo em uma plantação comercial de pinus (Pinus taeda L.) no bioma da Mata Atlântica para investigar (1) a contribuição da fauna do solo para a perda de massa da serapilheira; (2) a atividade alimentar da fauna edáfica na serapilheira dentro das estações do ano. As bolsas de decomposição com acículas de pinus (5 g, peso seco) foram preparadas como tratamentos de exclusão para a fauna do solo de diferentes tamanhos, variando o tamanho da malha (2 mm e 0,06 mm). As bolsas de decomposição foram removidas após 60, 120, 180, 240, 300 e 365 dias para estimar as taxas de decomposição. Bait laminas foram expostos sazonalmente e horizontalmente na superfície do solo para determinar a atividade de alimentação da fauna na serapilheira. Encontramos: (1) nenhuma diferença na perda de massa da serapilheira e na taxa de decomposição quando a macrofauna do solo e a maior parte da mesofauna foram excluídas; (2) a atividade alimentar dos organismos da serapilheira foi maior no verão, provavelmente estimulada por uma combinação de alta temperatura e umidade. Em plantios comerciais de pinus, podemos concluir que a ciclagem de nutrientes é mais lenta do que em áreas naturais, o que está relacionado às características das acículas, descritas na literatura. Nossos resultados indicaram que a macro e a mesofauna do solo desempenham um papel menor na decomposição da serapilheira em plantios comerciais de pinus, indicando que o processo de decomposição em tais povoamentos está mais relacionada à atividade dos microrganismos.

“…Collectively, the soil fauna is a major consumer and decomposer and is therefore an essential component of the forest ecosystem [6,7]. As the "engineer of the soil ecosystem", soil fauna plays an important role in dissolving residues and altering biogeochemical cycles [8,9]. However, our understanding of the responses of soil fauna community to increased levels of N input is still limited.…”

Soil fauna is critical for maintaining ecosystem functioning, and its community could be significantly impacted by nitrogen (N) deposition. However, our knowledge of how soil-faunal community composition responds to N addition is still limited. In this study, we simulated N deposition (0, 50, 100, 150, and 300 kg N ha−1 year−1) to explore the effects of N addition on the total and the phytophagous soil fauna along the soil profile (0–10, 10–25, and 25–40 cm) in poplar plantations (Populus deltoids) on the east coast of China. Ammonium nitrate (NH4NO3) was dissolved in water and sprayed evenly under the canopy with a backpack sprayer to simulate N deposition. Our results showed that N addition either significantly increased or decreased the density (D) of both the total and the phytophagous soil fauna (Dtotal and Dp) at low or high N addition rates, respectively, indicating the existence of threshold effects over the range of N addition. However, N addition had no significant impacts on the number of groups (G) and diversity (H) of either the total or the phytophagous soil fauna (Gtotal, Gp and Htotal, Hp). With increasing soil depth, Dtotal, Dp, Gtotal, and Gp largely decreased, showing that the soil fauna have a propensity to aggregate at the soil surface. Htotal and Hp did not significantly vary along the soil profile. Importantly, the threshold effects of N addition on Dtotal and Dp increased from 50 and 100 to 150 kg N ha−1 year−1 along the soil profile. Fine root biomass was the dominant factor mediating variations in Dtotal and Dp. Our results suggested that N addition may drive changes in soil-faunal community composition by altering belowground food resources in poplar plantations.
