Soil biota play essential roles in delivering key ecosystem goods and services, and are both
directly and indirectly responsible for acting in many important functions (nutrient release, soil
structure maintain, contribution to water storage). It is thus essential to characterize both the
species diversity and the biological functions.
In order to monitor soil biodiversity (species and function) in relation to land use (mainly agricultural
practices) and pedoclimatic parameters, a French program « RMQS-biodiv » was developed
at a wide regional scale (Brittany). An important national research collaboration (12 research
teams) supported the program, that undertook the study of several biological parameters such
as macrofauna diversity (earthworms, total macro-invertebrates), mesofauna diversity (acarina
and collembola), microorganisms (nematodes diversity, microbial biomass, bacterial and fungal
diversity), as well as functional biological parameters (soil respiration, humus index, macrofauna
and mesofauna activity: biogenic structure, feeding activity).
This program was connected to a larger soil monitoring network developed at national scale
(Soil Quality Measurement Network- RMQS) which monitored soil parameters (chemistry, physic)
and agricultural management using a regular grid (16 X 16 km) covering the whole national
territory. The link between these two programs allowed the study of biological parameters in the
light of soil and agricultural characteristics, and thus the definition of biological indicators.
The results obtained from the analysis of 115 sites sampled in 2006 and 2007, will be discussed
in terms of relevance of these biological criteria as indicators, and in fine of their transfer to field
actors (technicians) who are in charge of new tool implementation on agronomical management
assistance.
Furthermore, the results will also be discussed with respect to propositions and
recommendations made by the ENVASSO project (Environmental Assessment of Soil for
Monitoring), especially the biological criteria proposed by the European project and the hierarchy
of these criteria. MenosSoil biota play essential roles in delivering key ecosystem goods and services, and are both

The efficient use of fodder and grassland as the basis of animal feed represents a way of raising productivity and reducing production costs. In this scenario, elephant-grass stands out among the most used forages in the intensive animal production systems in the world mainly due to its high productive potential, support capacity and nutritional quality. The purpose of this work was to estimate genetic parameters for the selection of elephant-grass (Pennisetum purpureum Schumach.) clones for forage production in two seasons, a period of water restriction and the total period of study. We evaluated 80 accessions of elephant-grass by means of the mixed-models methodology (REML/BLUP). The evaluation of DM yield (DMY) of the different genotypes were executed in edaphoclimatic conditions in Campos dos Goytacazes, Rio de Janeiro, Brazil. The Selegen-REML/BLUP software accomplished the statistical and genetic analyses. It was seen that the DMY trait was with a low estimate of coefficient of genotypic variation (3.08%), which demonstrates possible difficulties with the selection for this trait. Heritability-coefficient estimate was 0.3606 for the dry season and 0.4193 for the total period. Those results were the variation in that trait due to genetic causes. Although those values may not be considered of high magnitude, they are of great interest for the breeding mainly because it is a polygenic trait. In both periods, genotypes 7, 25, 41, 43, 57, 58, 62, 64, 68, and 77 stood out among the others, since it presented the highest genetic gains for DMY, which will enhance progress in the evaluated trait.
