The objective of this study is to contribute to improve understanding of the ë Decoada í phenomenoní, the local term for the seasonal alteration of limnological parameters, including depletion of dissolved oxygen that can cause natural fish kills, in the Pantanal Wetlands (Mato Grosso do Sul State, Brazil). Two water bodies, adjacent to the Paraguay River (BaÌa Tuiui ̇ and Bracinho) were studied over a hydrological period (April 2008 to February 2009). The sampling plan was prepared using GIS tools. In each environment a grid of 2 per 12 square cells of 70 meters side was created. It was positioned in its center to guide the sampling during rising and flood phases as well as in the drainage and low-water phases. The bimonthly sampling included ten randomly selected sample points. The measured limnological variables were ordinate, using a PCA for each studiedsite. A strong influence of the flood pulse was observed on them, with particular changes occurring during the ëdecoadaí phenomenon. |

In the frame of the project ?Conservation and sustainable management of below ground
biodiversity (GEF/UNEP-CIAT/TSBF)? soil organisms inventories were done in the biosphere
reserve of Los Tuxtlas around Santa Martha volcano. 3 Sites (LM, SF and VC) and 4 land use
(forest (S), fallow (A), pasture (P) and maize (M) were sampled, in 89 points . The sampled
organisms were the biological nitrogen fixators, the mychorrizal fungi, the nematodes, the
macrofauna (earthworms, ants, termites, beetles, millipedes, centipedes?). In each point the
samples for the microorganisms and nematodes came from a composite soil sample made of
12 cores of 5 cm diameter and 20 cm height. The macrofauna was sampled with monoliths
(25x25x30cm), Winkler bags and Pitfall traps. Some chemical parameters (pH, Na, K, Mg. Ca
and P Bray), physical (% H,EC, clay, lime, sand, ad, rd, slope) and organic parameters ( C, N,
NH4, NO3, litter and deshydrogenase and B-glucosidase activity) were measured in each points
from the composed sample.
In order to synthesized the results and to evaluate which parameters of the soil determine the
diversity of organisms the general indicator of soil quality (GISQ) was build after 4 subindicators
that evaluates the physical, chemical, organic matter and the macrofauna data. The construction
of the GISQ was made with PCA of each of the 4 sets of variables and a cluster analysis. Also
identification of species indicators (Ind Val) and coinertia analysis was carried out.
The PCA of the 4 set of variables showed significant separation among sites and among land
uses. LM site had the best soil quality, followed by SF and VC. In the land use system S showed
the best soil quality and M the lowest, although in some group of variables P and A uses presented
a quality near to S.
The highest GISQ (1.00-0.85) were from LM but in different land uses (S, A and P); the lowest
(0.49-0.21) were in VC in maize and pasture and in SF in maize. The cluster analysis did
discriminate 8 groups of the sampling points having a similar GISQ.
The Ind Val analysis extracted some species indicators many from the ants and the nematodes
and few from the earthworms, termites and mycorrhizal fungi.
The co-inertia analysis between soil quality indicators and species richness displayed that
some diplopodes and coleoptera and native earthworms required a high soil quality soil. Other
coleoptera, ants and exotic earthworms required a less rich soil although with a high quality in
organic matter. Finally ,the microorganisms (Rhizobia and mycorrhizal fungi), Nematodes and
Chilopoda, were more represented in poor quality soils MenosIn the frame of the project ?Conservation and sustainable management of below ground
