TLDR
Stable isotope ratio analysis of light elements offers a powerful research tool to reveal and quantify trophic relationships of earthworms in soil food webs, while molecular techniques can further enhance understanding of the interactions between earthworms and microorganisms and their functional significance.About:

Influence of Diet On the Distribtion of Nitrogen Isotopes in Animals
Michael J. DeNiro,Samuel Epstein +1 more
TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ^(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.

Microplastics in the Terrestrial Ecosystem: Implications for Lumbricus terrestris (Oligochaeta, Lumbricidae)
Esperanza Huerta Lwanga,Hennie Gertsen,Harm P.A. Gooren,Piet Peters,Tamás Salánki,Martine van der Ploeg,Ellen Besseling,Albert A. Koelmans,Violette Geissen +8 more
TL;DR: This study studied the survival and fitness of the earthworm Lumbricus terrestris exposed to microplastics in litter at concentrations of 7, 28, 45, and 60% dry weight, percentages that, after bioturbation, translate to 0.2 to 1.2% in bulk soil.

Effects of Microplastics in Soil Ecosystems: Above and Below Ground.
TL;DR: Evidence is provided that microplastics manufactured of HDPE and PLA, and synthetic fibers can affect the development of L. perenne, health of A. rosea and basic, but crucial soil properties, with potential further impacts on soil ecosystem functioning.

The Ecology of Soil Carbon: Pools, Vulnerabilities, and Biotic and Abiotic Controls
TL;DR: This analysis suggests root inputs are approximately five times more likely than an equivalent mass of aboveground litter to be stabilized as SOM, and that fungi and bacteria, and soil faunal food webs, and mineral associations drive stabilization at depths greater than ∼30 cm.

Plastic bag derived-microplastics as a vector for metal exposure in terrestrial invertebrates
Mark E. Hodson,Calum A. Duffus-Hodson,Andy Clark,Miranda T. Prendergast-Miller,Karen L. Thorpe +4 more
TL;DR: It is indicated that microplastics could act as vectors to increase metal exposure in earthworms, but that the associated risk is unlikely to be significant for essential metals such as Zn that are well regulated by metabolic processes.

Diversity of the human intestinal microbial flora.
Paul B. Eckburg,Elisabeth M. Bik,Charles N. Bernstein,Elizabeth Purdom,Les Dethlefsen,Michael Sargent,Steven R. Gill,Karen E. Nelson,David A. Relman,David A. Relman,David A. Relman +10 more
TL;DR: A majority of the bacterial sequences corresponded to uncultivated species and novel microorganisms, and significant intersubject variability and differences between stool and mucosa community composition were discovered.

Michael J. DeNiro,Samuel Epstein +1 more
TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.

Recruitment of entomopathogenic nematodes by insect-damaged maize roots
Sergio Rasmann,Tobias G. Köllner,Jörg Degenhardt,Ivan Hiltpold,Stefan Toepfer,Ulrich Kuhlmann,Jonathan Gershenzon,Ted C. J. Turlings +7 more
TL;DR: The first identification of an insect-induced belowground plant signal, (E)-β-caryophyllene, which strongly attracts an entomopathogenic nematode, is reported, which should help enhance the efficacy of nematodes as biological control agents against root pests like D. virgifera.
