Soil fauna refers to eukaryotic, heterotrophic organisms such as earthworms, collembolans, mites, nematodes, and protozoa that live in the soil, contributing to nutrient cycling and microbial interactions within the soil ecosystem.

- Soil Biota
Based on body size, habitat preference, and food consumed, soil fauna are generally assigned to one of three functional groups – microfauna, mesofauna or macrofauna (Table 1). In forests, approximately 90% of the soil faunal biomass is usually found in the top 10 cm of humus and soil.

We have all already turned over or seen soil turned over with a spade: we can easily distinguish the life that resides there, at least the visible part (the largest organisms), which is only a small part of the life that the soil harbors. Indeed, most of this diversity of organisms is invisible to our eyes because they are microscopic. The soil is ...
Soil micro-organisms are extremely abundant and of great taxonomic and functional diversity. They include bacteria, fungi, microalgae, archaea and protists . The biological functioning of soils is strongly linked to microbial activity, which gives these microorganisms a major role in many soil functions as discussed below.
If we take the image of observing the soil with a spade, we can easily distinguish animals of very different sizes: this is used to classify the soil fauna into four groups : microfauna, mesofauna, macrofauna and megafauna. The soil fauna is defined as all the animals that have at least part of their life cycle in the soil. This fauna represents ne...
Over the past few decades, many research programson soil biodiversity have sought to identify relevant indicators, to produce a comprehensive mapping and/or to identify soil uses influencing soil biodiversity. Among the methods of researching functional characteristics of organisms, the one called “ecological traits and preferences” is very relevan...
Oct 17, 2022 · Soil invertebrates (i.e., soil fauna) are important drivers of many key processes in soils including soil aggregate formation, water retention, and soil organic matter transformation. Many soil fauna groups directly or indirectly participate in litter consumption.

Jan 1, 2024 · The biodiversity of soil animals (fauna) is large, and fauna critically affect soil processes by feeding and fragmenting plant materials and organic substrates. Soil fauna exist in food webs, with a range of feeding modes (trophic levels).
Soil animals can be conventionally grouped by size classes: macrofauna (cm; enchytraeids, earthworms, macroarthropods), mesofauna (mm; microarthropods, mites and collembolan), and microfauna...
Apr 21, 2014 · Soils are multicomponent and multifunction systems which provide a series of “ecosystem goods” (biomass production) to humans, but also many “regulating services” (e.g., SOM decomposition, soil structure maintenance, nutrient cycling, etc.) which ensure ecosystem sustainability.
