Levantamento florístico em remanescente de floresta ripária no alto rio Paraná: Mata do Araldo, Porto Rico, Paraná, Brasil

The purpose of this study was to realize a floristic survey in riparian forest remains of the Upper Paraná River, under domain of the submontane seasonal semideciduous forest, located in Porto Rico, Paraná, Brazil (53°19'3 W e 22°47'37 S). Within and in the neighborhood of 10.000 m2 area (100 m × 100 m), 165 species were surveyed, in 124 genera and 60 families, distributed in arboreous, shrubs, herbs, climbers and hemiparasites. Leguminosae, Myrtaceae, Poaceae, Rubiaceae, and Bignoniaceae were the families with the highest species' richness, showing together 33.33%, and the genera more representative were Eugenia, Casearia, Guarea, Inga, Panicum, and Solanum, with 12.73% of the species. Though the perturbations verified in the forest remains, eight species were rare for this type of vegetation and 12 were listed as fishes natural food.

Diagnóstico de uma área compactada por atividade minerária, na floresta amazônica, empregando métodos geoestatísticos à variável resistência mecânica à penetração do solo

A quite common problem in the recovery of degraded areas in the mineral exploration understands the compaction of the soil due to the intense traffic of machines and earth movement. The most common problem of the compaction of a degraded surface is: increase of the mechanical resistance to the penetration of the rooats, reduction of the aeration, alteration of the water flow and heat. Thus the present work had the basic objective of diagnosing the compaction of a degraded area by mining in a space way, through the mechanical resistance the way penetration to guide a future subsoiling in the place seeking recovery. Through the studies it was concluded that the kriging method in agreement with the space variation allows the division of the area studies in sub areas facilitating a future work to reduce cost and unnecessary interference to the atmosphere. The method was shown quite appropriate and it can be used in diagnosis of the compaction in a degraded area by mining, foreseeing subsoiling need.

Estimativa Da Água No Solo Em Floresta de Eucalyptus Grandis

The study aimed to assess the moisture and density of the soil, the amount of water stored in the profile, and the average soil's porosity with Eucalyptus grandis reforestation, compared to bare soil. The study areas are located in the Paulista region, in São Paulo, Brazil. The samples were collected in layers of 0, 20, 40, 60, 100 and 300 cm, in the months of April, June, August and October 2008. The results show that the density is lower and the porosity is higher in Eucalyptus forest soil compared to bare soil, due to the higher content of organic matter in forest leaf litter. Furthermore, the forest soil has a lower amount of water stored in profile than the bare soil without vegetation.

Variabilidade espacial dos atributos físicos em um Argissolo Vermelho sob floresta

This study aim to evaluate the spatial variability of soil physical attributes in of Alfissol forest in Manicoré region, AM. The mapping of an agroforestry growing area of 70×70m was made using a regular grid sampling of 10 × 10m. In each grid, soil samples were collected at 0.0-0.2 and 0,40-0,60 m depth, with a total of 128 sample points. Physical analyses were made (texture, soil bulk and particles density, macro and microporosity, total porosity and aggregates stability in water). With the exception of DMG, DMP and class aggregates <1.00 mm had all the physical attributes spatial dependence structure ranging from moderate to weak. Values were above the range established in the mesh (12.00 to 45.56 m), enabling to make a basis for future studies in forest area. The physical attributes presented in kriging maps different spatial behavior, however there are relationships between these attributes shown by geostatistics proving that this is effective tool for studies in forest area.
