The Pantanal is an ecosystem with 250 thousand km2 in length located in northwestern Mato
Grosso and Mato Grosso do Sul, encompassing the northern Paraguay and eastern Bolivia, is
considered by UNESCO World Natural Patrimony and Biosphere Reserve. The soils in general
have to be quite intemperized and leachate, low natural fertility. The organic matter is the largest
source of nutrients for growth and maintenance of a lush vegetation and rich in aquatic species,
soil soaked, semi-flooded and dry. The rates of decomposition of organic matter and release of
nutrients are of vital importance for crop production and consequently maintain the micro, meso
and macrofauna soil and also higher than the animals that live in this ecosystem. The organisms
are responsible for soil degradation and decomposition of organic matter and cycling of nutrients.
The survey was conducted over a period of end of drought, October 2002. He was given 50
points inside the gallery forest, of which 15 points were hit, and these were removed 2 samples
of litter in the depths of 1 to 10 cm (using for this ruler of 300 mm) through the use of funnels of
Berlese (modified ) Filling the funnel with leaves. The funnels have a cylindrical top of 8x5 cm
(total 244.44 cm3 capacity) separated by a screen of wire mesh of 2 cm, and funneled a part of
20 cm in length, with a perforation of 2 cm from the base. After collecting the funnels were placed
on a table exhibiting lamps containing five of 25 W, forcing the organisms to flee the light and
heat, they fall in flasks of 5x3 cm, which contained liquid preservative, to sustain them. The
material was exposed for three days and after were sorted, counted and identified. The largest
number of Acari occurred in the depth of 4, 6, 7, 10 cm, while the lowest in depth of 2 and 3 cm.
The Collembola occurred in greater numbers to 3 and 4 cm in depth and the lowest number 5
and 6 cm. As for Insecta the highest incidence was in the depths of 6, 7 and 10 cm and the
lowest in 2, 3, 4 and 5 cm. Protura, Diplura, Arachnida, were more frequent in the 5, 6 and 10
cm, and the fewest in 2, 3 and 4. The number of organisms per square metre was: Acari 16,780,
13,255 Collembola, Insecta and 1,113 other 393. MenosThe Pantanal is an ecosystem with 250 thousand km2 in length located in northwestern Mato
