11.1 Fungi as food
Fungus fruit bodies are used as food by many invertebrates and are large enough to be used by many mammals, including large mammals like deer and primates (Hanson et al., 2003). In most soils, though, there is such a large amount of fungal mycelium that hyphae make a major contribution to food webs by being eaten by invertebrates including insects, mites, nematodes and molluscs. Microarthropods are responsible for shredding organic matter in soil (and so prepare it for the final mineralisation processes carried out by microbes), but about 80% of the tens of thousands of microarthropod species in forest soils are fungivores (or mycophagous); meaning they depend on the fungal mycelium for food. We have introduced many of these small animals before (Chapter 1); check out the reminder in this Resources Box.
Life in the soil
Thomas E. Loynachan, Professor of Agronomy and Microbiology at Iowa State University, has created a set of 16 short digital videos showing the scope of life in the soil.

In this Chapter we will illustrate some of the most important features with a short foray into the outside world. Nothing too strenuous; join us on a short walk to the bottom of our suburban garden in Stockport, Cheshire (Fig. 1).

This biological survey was completed in my back garden and the aerial map image shows the site of the observations (arrow) and makes the point that biology and natural history extends to the urban environment.
