• Great paper on models• But they totally ignored
the fauna!

Soil fauna totally ignored!
ESSEM COST Action ES1406
Let us reconcile…
• In the end of the article, the authors state:
Join forces and connect research communities „(…) There are those studying litter decomposition, with a focus on the biotic breakdown of plant inputs (…)“
So, what can WE do about it?
Interestingly, none of the 46 papers citing this article (by August 8, 2012) focused on soil fauna!

We challenged them!
Soil fauna: key to soil organic matter dynamics and modelling (KEYSOM)“We argue that explicit consideration of soil animals is essential to make realistic modelling predictions and detect expected non‐linear responses to Global Change.”

State‐of‐the‐art Key points Reasons for the ActionUnderstanding and modelling SOM is essential for managingsoil fertility, agricultural productivity and soil ecosystemservices like nutrient cycling and carbon sequestration.
Soil animals are crucial but not sufficiently acknowledged inSOMmodelling.
• Limited communication (linkages) between biogeochemistry,microbiology and soil ecology
• Lack of [awareness of] data on soil animals (both field andlab experiments)
• Soil ecologists: two rather different ways to explainprocesses: “food‐web” vs. “ecosystem egineering”

incomplete!• Which parameters should be
considered?
