Diversity and functional structure of soil animal communities suggest soil animal food webs to be buffered against changes in forest land use

Melanie M. Pollierer et al.

Summary: A diverse community of animals inhabits forest soil and litter, relying on dead organic matter as habitat and food resource. Despite significant effects of forest management on resource abundance and quality, soil animal diversity and functional community composition show resilience against disturbance and forest land use. The biomass of most soil fauna functional groups is not directly affected by forest management or resource abundance/quality, but instead, detritivore biomass is heavily influenced by soil pH.

Stable isotopes of amino acids indicate that soil decomposer microarthropods predominantly feed on saprotrophic fungi

Melanie M. Pollierer et al.

Summary: Soil microarthropods mainly rely on saprotrophic fungi rather than ectomycorrhizal fungi for nutrition, with plant detritus serving as a significant basal resource. The study provides insight into the food web structure of soil microarthropods and the relative importance of mycorrhizal and saprotrophic fungi for soil food web nutrition, addressing a long-standing mystery in soil food web ecology.

The flux of root-derived carbon via fungi and bacteria into soil microarthropods (Collembola) differs markedly between cropping systems

Zhipeng Li et al.

Summary: The study found that variations in microbial community structure between different cropping systems can affect the incorporation of root-derived carbon into soil microbivores. Changes in the flux of root carbon into bacterial and fungal resources among cropping systems result in differential utilization of these resources by soil microbivores.

The Impact of Root-Derived Resources on Forest Soil Invertebrates Depends on Body Size and Trophic Position

Sarah L. Bluhm et al.

Summary: Forest soil food webs are assumed to be primarily sustained by root-derived resources, but disrupting this flux into soil animals has varying effects based on body size, with smaller mesofauna being more sensitive than micro- and macrofauna. Soil animal communities show resilience to deprivation of root-derived resources, with mesofauna playing a key role in energy flow in temperate forests.
