?RMQS BioDiv? is a pilot program which values biological components of Armorican soils
(Brittany region, France). Several biological groups, such as all macro-invertebrates,
earthworms, acari, collembola, nematodes, microflora, and also some activity index are
studied. This program is linked to the national French Soil Quality Measurement Network
(classical RMQS) and both generate a large data set according to an important grid sampling
scheme (1 site each 16 km). In this context, a data analysis strategy must be developed in
order to highlight the indicative value of structural and functional soil biodiversity and its
relationship with environmental variables. To reach this aim, an analytical methodology for
data treatment was constructed following a hierarchical scheme composed of successive
steps. In a first step, the data set of each biological group was analysed independently by
the means of descriptive and exploratory statistics. In a second step, global analyses were
conducted on the whole soil biological dataset. These analyses included correlations between
taxa, descriptors of biological diversity, community pattern descriptions and multivariate
analyses. In a third step, environmental factors, which could influence soil biota variability
(distribution/heterogeneity), were integrated into the analysis. Potential explicative variables
within pedological characteristics, physical and chemical properties, land use and
management practices were assessed to explain the community structures. For that, landscape,
environmental and agronomical typologies of the sampled sites were first performed.
Then, the relationships between soil biological components and potential explicative variables
were investigated by using multivariate and multitable approaches. Furthermore, the spatial
variability analysis was ensured by the grid sampling scheme, thus informed whether soil
biodiversity displayed spatial patterns at the regional scale and how these patterns were
related to the site characteristics. Finally, the relevance of this analytical approach and the
results will be discussed with respect to ENVASSO recommendations (data analysis, results
representation ?). Menos?RMQS BioDiv? is a pilot program which values biological components of Armorican soils
