Peach (Prunus persica L.) rootstock cultivars are typically selected for scion compatibility, ease of propagation, vigor, development, flowering season, yield, low need for cold temperatures, resistance to diseases, effects on the physical-chemical characteristics of the fruit, plant longevity and adaptation to adverse edaphoclimatic conditions. However, kinetic parameters related to nutrient uptake efficiency are usually not considered, such as those of nitrate (NO3 −) and ammonium (NH4 +). N is the nutrient that most impacts growth and yield. The objective of this study was to show the importance of the kinetic parameters of NO3 − and NH4 + uptake as additional criteria for selecting peach rootstocks. The experiment was conducted in a greenhouse. Three rootstock (?Aldrighi?, ?Tsukuba1? and ?Clone 15′) were grown for 30 days in a pot containing 0.1 mol L-1 CaSO4 solution to reduce internal reserves of N. Afterwards, the plants were placed in Hoagland nutrient solution, where periodic collections of the nutrient solution were carried out for three days and the concentrations of NO3 − and NH4 + were determined. After the third day of collecting the solution, the plants were collected and then separated into leaves, roots and stems. Dry matter and total N content were assessed. The kinetic parameters related to NO3 − and NH4 + uptake (maximum uptake rate - Vmax, affinity constant - Km, Minimum concentration - Cmin, Influx - I) were calculated using Cinética software. The most efficient rootstock for NO3 − and NH4 + uptake was ?Tsukuba1?, as it showed the lowest values of Cmin and Km and the highest values of Vmax and Imax for NO3 − and NH4 +. NO3 − uptake in ?Tsukuba1? and ?Aldrighi? showed a two-phase uptake pattern, suggesting the presence of low and high affinity transport systems. On the other hand, NH4 + uptake in the three cultivars apparently followed a one-phase uptake pattern, suggesting the presence of a high affinity transport system. The kinetic parameters of NO3 − and NH4 + uptake are additional criteria that can be used in selecting peach rootstocks, as they directly influence shoot and root dry matter production and N accumulation in leaves.

The Pantanal is the second largest biome flooded the planet earth, covering an area of 140,000
km2. The low slope of this vast basin of the Paraguay river hampers the flow of water and in
combination as the half-relief, leads to the emergence of environments characteristic associated
with the vegetation in mosaic with the old alluvial dikes, causing thus flooded environments,
semi - flooded and dried (Pasture and Paratudal), occurring in this way edaphic fauna adapted
to these conditions. The soil and litter this biome has a diverse fauna of mites, springtail, insects,
crustaceans and miriapods. Despite this wealth of organisms and edaphic semi-edaphics, little
is known yet on bioecology and its classification. Aiming edaphic know the wildlife of this region,
proposes to raise the analysis faunistic, diversity and abundance of these bodies, the four types
of environments. The survey was conducted in Step of Otter, city of Corumbá-MS. The soil of the
region is hydromorphic soil. The areas that remain flooded almost the entire year; soil halfflooded
(remains flooded during the flood of the river Miranda); dry soil (Grassland and Paratudal)
of pasture land consists of native grasses, Paratudal, coverage of grass native to mixed ipê
trees of yellow (Tabebuia sp). The collections were made in eight transects (of the four areas), in
each transect were collected four samples of soil, removed 10 meters between each point of
collection, totaling 32 points for sampling. The soil was collected with the help of the funnel
Berlese (modified) to eight centimeters in diameter, by five centimeters deep. Then the material
was placed in exhibitor table, equipped with five lamps of 25W, and remained in this table for
three days. Below each funnel was placed a plastic bottle of 10x5 cm, containing a portion of
liquid preservative to collect the bodies. The sorting and identification of bodies were made
with a stereomicroscope mark Carl Zeiss. The largest number and bodies were found in the
environment semi-flooded (216), with 118 mites, 80 springtail, 23 insects and crustaceans 3. In
the environment flooded were found (207), 66 mites, 80 springtail, 58 insects and 3 crustaceans.
In Pasture (79), 47 mites, 20 springtail, 12 insects. In Paratudal (136), 92 mites, 24 springtail
