We evaluated photosynthetic performance, growth, and biomass partitioning in tree species Anadenanthera falcata and Stryphnodendron adstringens growing under full solar irradiance and in the shade equivalent to that found in understory of the Cerradão physiognomy. The study was conducted free of water stress by watering, in São Carlos, state of São Paulo, Brazil, until 1140 days after sowing (DAS). We obtained irradiance and leaf gas exchange data with a portable infrared gas analyzer. In the sunny area, both species presented higher respiration in the dark, light saturation point, regular and potential photosynthetic capacity and higher apparent carboxylation efficiency. Besides, under full solar irradiance, the total biomass, leaf area, height, stem diameter, and the total number of leaflets were significantly (p<0.05) higher at 240, 360, and 570 DAS. S. adstringens did not survive in the shade after 1140 DAS, while A. falcata showed a survival of 100% under both irradiance regimes. The irradiance attenuation in dense physiognomies of cerrado vegetation, as that found in Cerradão, affected several levels of plant organization since early growth. Our results highlighted how natural irradiance availability in Cerrado vegetation determined per se the carbon balance, the development and the survival of tree species. |

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
