Soil ecologists often operate with functional groups to infer the effects of individual taxa on ecosystem functions and services. Simultaneous assessment of the functional roles of multiple taxa is possible using food‐web reconstructions, but our knowledge of the feeding habits of many taxa is insufficient and often based on limited evidence. Over the last two decades, molecular, biochemical and isotopic tools have improved our understanding of the feeding habits of various soil organisms, yet this knowledge is still to be synthesised into a common functional framework. Here, we provide a comprehensive review of the feeding habits of consumers in soil, including protists, micro‐, meso‐ and macrofauna (invertebrates), and soil‐associated vertebrates. We have integrated existing functional group classifications with findings gained with novel methods and compiled an overarching classification across taxa focusing on key universal traits such as food resource preferences, body masses, microhabitat specialisation, protection and hunting mechanisms. Our summary highlights various strands of evidence that many functional groups commonly used in soil ecology and food‐web models are feeding on multiple types of food resources. In many cases, omnivory is observed down to the species level of taxonomic resolution, challenging realism of traditional soil food‐web models based on distinct resource‐based energy channels. Novel methods, such as stable isotope, fatty acid and DNA gut content analyses, have revealed previously hidden facets of trophic relationships of soil consumers, such as food assimilation, multichannel feeding across trophic levels, hidden trophic niche differentiation and the importance of alternative food/prey, as well as energy transfers across ecosystem compartments. Wider adoption of such tools and the development of open interoperable platforms that assemble morphological, ecological and trophic data as traits of soil taxa will enable the refinement and expansion of the multifunctional classification of consumers in soil. The compiled multifunctional classification of soil‐associated consumers will serve as a reference for ecologists working with biodiversity changes and biodiversity–ecosystem functioning relationships, making soil food‐web research more accessible and reproducible."],["dc.description.sponsorship","Alexander von Humboldt‐Stiftung http://dx.doi.org/10.13039/100005156"],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659"],["dc.description.sponsorship","Czech Academy of Sciences ‐ Deutscher Akademischer Austauschdienst http://dx.doi.org/10.13039/501100001655"],["dc.identifier.doi","10.1111/brv.12832"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/98852"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-517"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B08: Struktur und Funktion des Zersetzersystems in Transformationssystemen von Tiefland-Regenwäldern"],["dc.relation.eissn","1469-185X"],["dc.relation.issn","1464-7931"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited."],["dc.subject.gro","sfb990_reviews"],["dc.title","Feeding habits and multifunctional classification of soil‐associated consumers from protists to vertebrates"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","overview_ja"],["dspace.entity.type","Publication"]]

Predators are often larger than their prey in food chains, but empirical evidence for positive body mass–trophic level scaling for entire food webs mostly comes from marine communities on the basis of unicellular producers. Using published data on stable isotope compositions of 1,093 consumer species, we explored how trophic level scales with body size, food web type (green vs. brown), and phylogenetic group across biomes. In contrast to widespread assumptions, the relationship between body size and trophic level of consumers—fromprotists to large vertebrates—was not significant per se but varied among ecosystemtypes and animal groups. The correlation between body size and trophic level was strong in marine consumers, weak in freshwater consumers, and absent in terrestrial consumers, which was also observed at the scale of local food webs. Vertebrates occupied higher trophic positions than invertebrates, and green trophic chains were longer than brown ones in aquatic (primarily marine) but not in terrestrial food webs.

Belowground consumers create complex food webs that regulate functioning, ensure stability and support biodiversity both below and above ground. However, existing soil food-web reconstructions do not match recently accumulated empirical evidence and there is no comprehensive reproducible approach that accounts for the complex resource, size and spatial structure of food webs in soil. Here I build on generic food-web organisation principles and use multifunctional classification of soil protists, invertebrates and vertebrates, to reconstruct a ‘multichannel’ food web across size classes of soil-associated consumers. I infer weighted trophic interactions among trophic guilds using feeding preferences and prey protection traits (evolutionarily inherited traits), size and spatial distributions (niche overlaps), and biomass-dependent feeding. I then use food-web reconstruction, together with assimilation efficiencies, to calculate energy fluxes assuming a steady-state energetic system. Based on energy fluxes, I propose a number of indicators, related to stability, biodiversity and multiple ecosystem-level functions such as herbivory, top-down control, translocation and transformation of organic matter. I illustrate this approach with an empirical example, comparing it with traditional resource-focused soil food-web reconstruction. The multichannel reconstruction can be used to assess ‘trophic multifunctionality’ (analogous to ecosystem multifunctionality), i.e. simultaneous support of multiple trophic functions by the food web, and compare it across communities and ecosystems spanning beyond the soil. With further empirical validation of the proposed functional indicators, this multichannel reconstruction approach could provide an effective tool for understanding animal diversity–ecosystem functioning relationships in soil. This tool hopefully will inspire more researchers to describe soil communities and belowground–aboveground interactions comprehensively. Such studies will provide informative indicators for including consumers as active agents in biogeochemical models, not only locally but also on regional and global scales."],["dc.description.sponsorship","Alexander von Humboldt‐Stiftung http://dx.doi.org/10.13039/100005156"],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659"],["dc.description.sponsorship","Czech Academy of Sciences (CAS) and Deutscher Akademischer Austauschdienst"],["dc.description.sponsorship","GEORG‐AUGUST‐UNIVERSITAET GOTTINGEN"],["dc.identifier.doi","10.1111/brv.12857"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/107310"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-561"],["dc.publisher","Blackwell Publishing Ltd"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B08: Struktur und Funktion des Zersetzersystems in Transformationssystemen von Tiefland-Regenwäldern"],["dc.relation.eissn","1469-185X"],["dc.relation.issn","1464-7931"],["dc.rights","CC BY 4.0"],["dc.subject.gro","sfb990_reviews"],["dc.title","Multifunctionality of belowground food webs: resource, size and spatial energy channels"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","overview_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Here we provide an overview of recent advances in uncovering the trophic structure of soil food webs using natural variations in stable isotope ratios. We discuss approaches of application, normalization and interpretation of stable isotope ratios along with methodological pitfalls. Analysis of published data from temperate forest ecosystems is used to outline emerging concepts and perspectives in soil food web research. In contrast to aboveground and aquatic food webs, trophic fractionation at the basal level of detrital food webs is large for carbon and small for nitrogen stable isotopes. Virtually all soil animals are enriched in 13 C as compared to plant litter. This 'detrital shift' likely reflects preferential uptake of 13 C-enriched microbial biomass and underlines the importance of microorganisms, in contrast to dead plant material, as a major food resource for the soil animal community. Soil organic matter is enriched in 15 N and 13 C relative to leaf litter. Decomposers inhabiting mineral soil layers therefore might be enriched in 15 N resulting in overlap in isotope ratios between soil-dwelling detritivores and litter-dwelling predators. By contrast, 13 C content varies little between detritivores in upper litter and in mineral soil, suggesting that they rely on similar basal resources, i.e. little decomposed organic matter. Comparing vertical isotope gradients in animals and in basal resources can be a valuable tool to assess trophic interactions and dynamics of organic matter in soil. As indicated by stable isotope composition, direct feeding on living plant material as well as on mycorrhizal fungi is likely rare among soil invertebrates. Plant carbon is taken up predominantly by saprotrophic microorganisms and channelled to higher trophic levels of the soil food web. However, feeding on photoautotrophic microorganisms and non-vascular plants may play an important role in fuelling soil food webs. The trophic niche of most high-rank animal taxa spans at least two trophic levels, implying the use of a wide range of resources. Therefore, to identify trophic species and links in food webs, low-rank taxonomic identification is required. Despite overlap in feeding strategies, stable isotope composition of the high-rank taxonomic groups reflects differences in trophic level and in the use of basal resources. Different taxonomic groups of predators and decomposers are likely linked to different pools of organic matter in soil, suggesting different functional roles and indicating that trophic niches in soil animal communities are phylogenetically structured. During last two decades studies using stable isotope analysis have elucidated the trophic structure of soil communities, clarified basal food resources of the soil food web and revealed links between above- and belowground ecosystem compartments. Extending the use of stable isotope analysis to a wider range of soil-dwelling organisms, including microfauna, and a larger array of ecosystems provides the perspective of a comprehensive understanding of the structure and functioning of soil food webs."],["dc.identifier.doi","10.1111/brv.12434"],["dc.identifier.pmid","29920907"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62319"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B08: Struktur und Funktion des Zersetzersystems in Transformationssystemen von Tiefland-Regenwäldern"],["dc.relation.eissn","1469-185X"],["dc.relation.issn","1464-7931"],["dc.subject.gro","sfb990_reviews"],["dc.title","Uncovering trophic positions and food resources of soil animals using bulk natural stable isotope composition"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","overview_ja"],["dspace.entity.type","Publication"]]

This statement applies to individual animals within a species and thus species often serve as the functional units in ecological studies. Species are further grouped into higher‐ranked taxonomic units based on their morphological similarity and thus are also expected to be ecologically similar. On the other hand, theory predicts that strong competition between closely related species may result in differentiation of ecological niches. Due to high diversity and limited taxonomic expertise, soil food webs are often resolved using supraspecific taxa such as families, orders or even classes as functional units. Here, we tested the trophic differentiation and consistency of supraspecific taxa across major lineages of temperate forest soil invertebrates: Annelida, Chelicerata, Myriapoda, Crustacea and Hexapoda. Published data on stable isotope compositions of carbon and nitrogen were used to infer basal resources and trophic level, and explore the relationship between taxonomic and trophic dissimilarity of local populations. Genera and families had normal and unimodal distributions of isotopic niches, suggesting that supraspecific taxa are trophically consistent. The isotopic niche of local populations varied considerably resulting in large overlap of niches among species. Within the same genus, the effect of species identity on stable isotope composition of populations was not significant in 92% of cases. More than 50% of the variability in Δ15N values (trophic level) across lineages was explained by classes and orders, while the variability in Δ13C values (basal resources) was explained mostly by families and genera. The variability in stable isotope composition in Chelicerata and Hexapoda was explained by lower taxonomic ranks than in Myriapoda. We compiled a comprehensive list of mean Δ13C and Δ15N values of invertebrate taxa from temperate forest soils allowing to refine soil food web models when measurements of trophic niches of local populations are not feasible. Supraspecific taxa are meaningful as trophic nodes in food web studies, but the consistency varies among taxa and the choice of taxonomic resolution depends on the research question; generally, identification of taxa should be more detailed in more diverse taxonomic groups."],["dc.identifier.doi","10.1111/1365-2435.13309"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62884"],["dc.language.iso","en"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | B | B08: Struktur und Funktion des Zersetzersystems in Transformationssystemen von Tiefland-Regenwäldern"],["dc.relation.issn","0269-8463"],["dc.relation.orgunit","Zentrum für Biodiversität und Nachhaltige Landnutzung"],["dc.subject.gro","sfb990_reviews"],["dc.title","Trophic consistency of supraspecific taxa in below-ground invertebrate communities: Comparison across lineages and taxonomic ranks"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","overview_ja"],["dspace.entity.type","Publication"]]
