“…Distinct trophic niches of co-occurring Chilopoda species were confirmed by molecular gut content analyses, for example in Geophilomorpha and Lithobiidae (Bortolin, Fusco & Bonato, 2018). Presumably, predator-prey body size ratios in combination with habitat structure play an important role in trophic niche partitioning in Chilopoda (Schneider, dilution effects, the smaller species Lithobius crassipes benefited from higher amounts of leaf litter, presumably due to competitive release from larger predators and adaptations to hunt in smaller crevices (Günther et al, 2014).…”

“…springtails and mites), considerable progress has been achieved, with new and refined trophic classifications suggested (Maraun et al ., 2011; Potapov et al ., 2016b), the importance of alternative food resources (nematodes, bacteria, algae) emphasised (Heidemann et al ., 2014a; Ferlian et al ., 2015; Potapov et al ., 2018, 2021a) and processes of trophic niche differentiation and shifts quantified (Schneider et al ., 2004; Chahartaghi et al ., 2005; Klarner et al ., 2013; Birkhofer et al ., 2016b; Maraun et al ., 2020; Krause et al ., 2021). Finally, while the trophic classifications of macrofauna have remained largely the same, modern tools have allowed distinguishing assimilated from ingested components (Larsen et al ., 2016b) and have identified gradual niche differentiation among sympatric and morphologically similar species (Melody & Schmidt, 2012; Bortolin et al ., 2018). Modern tools also have been invaluable for the quantification of energy channelling from different resources by large‐sized generalist feeders (Larsen et al ., 2016b; Mader et al ., 2018).…”

Feeding habits and multifunctional classification of soil‐associated consumers from protists to vertebrates

Soil organisms drive major ecosystem functions by mineralising carbon and releasing nutrients during decomposition processes, which supports plant growth, aboveground biodiversity and, ultimately, human nutrition. 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.

“…Approximately 3300 centipede species have been described (Chipman et al 2014) and the majority of these taxa are distributed in tropical and subtropical regions. Six orders of centipedes are currently recognized, namely, Scolopendromorpha, Geophilomorpha, Lithobiomorpha, Scutigeromorpha, Craterostigmomorpha, and Devonobiomorpha (Bortolin et al 2018). Devonobiomorpha is an extinct order represented by a single species (Shear and Bonamo 1988) and the Craterostigmomorpha only occur in Tasmania and New Zealand (Undheim et al 2016).…”

Scolopendra mutilans L. Koch, 1878 is an important Chinese animal with thousands of years of medicinal history. However, the genomic information of this species is limited, which hinders its further application. Here, the complete mitochondrial genome (mitogenome) of S. mutilans was sequenced and assembled by next-generation sequencing. The genome is 15,011 bp in length, consisting of 13 protein-coding genes (PCGs), 14 tRNA genes, and two rRNA genes. Most PCGs start with the ATN initiation codon, and all PCGs have the conventional stop codons TAA and TAG. The S. mutilans mitogenome revealed nine simple sequence repeats (SSRs), and an obviously lower GC content compared with other seven centipede mitogenomes previously sequenced. After analysis of homologous regions between the eight centipede mitogenomes, the S. mutilans mitogenome further showed clear genomic rearrangements. The phylogenetic analysis of eight centipedes using 13 conserved PCG genes was finally performed. The phylogenetic reconstructions showed Scutigeromorpha as a separate group, and Scolopendromorpha in a sister-group relationship with Lithobiomorpha and Geophilomorpha. Collectively, the S. mutilans mitogenome provided new genomic resources, which will improve its medicinal research and applications in the future.

“…The class Chilopoda (Latreille, 1817) is one of the four major lineages of myriapods [ 1 ]. Six orders of centipedes are currently recognized, including five extant orders of Craterostigmomorpha (Pocock, 1902), Geophilomorpha (Pocock, 1895), Lithobiomorpha (Pocock, 1895), Scolopendromorpha (Pocock, 1895), and Scutigeromorpha (Pocock, 1895), and an extinct order of Devonobiomorpha [ 2 , 3 ]. The debate about the phylogeny of Chilopoda has been a heated discussion in recent years.…”

Based on morphological characteristics to make species identification, the cryptic species of the Scutigeromorpha can be greatly underestimated. The mitochondrial genome provides a desirable tool for the biological identifications and the discovery of the cryptic species. The capacity to acquire mitochondrial genome sequences has substantially improved in recent years using next-generation sequencing (NGS) technology. On the basis of the next-generation sequencing, we obtained four complete mitochondrial genomes of Thereuonema tuberculata (Wood, 1862) from Nanyang, Henan Province (NY), Nanchang, Jiangxi Province (NC), Jinan, Shandong Province (JN), and Dali, Yunnan Province (DL) in China with GenBank numbers OK513221, OL449685, ON058988 and ON058989, respectively. The lengths of the four mitochondrial genomes ranged from 14,903 to 14,909 bp. The composition and order of genes of the four mitochondrial genomes were identical to the published mitochondrial genome of Scutigera coleoptrata (Linnaeus, 1758) (Scutigeromorpha: Scutigerdae). It was the first time that the tandem repeats in the control region were detected in Scutigeromorpha. We also calculated the corrected pairwise genetic distance of four complete mitochondrial genomes of T. tuberculata, ranging from 7.7 to 15.2%. The results showed that the T.tuberculata NC belonged to the typical sample of T. tuberculata, and T. tuberculata DL was hypothesized as a cryptic species of T. tuberculata. Meanwhile, T. tuberculata NY and T. tuberculata JN were hypothesized as potential cryptic species of T. tuberculata in this study. In both BI and ML trees, the monophyly of Scutigeromorpha, Scolopendromorpha, Geophilomorpha, and Lithobiomorpha was forcefully advocated. Moreover, Scutigeromorpha was recovered as the sister clade of (Scolopendromorpha + (Lithobiomorpha + Geophilomorpha)). Four specimens of T. tuberculata were clustered into one clade, which was the sister to the clade of S. coleoptrata.
