Análise estrutural e aspectos do mosaico sucessional de uma floresta semidecídua em Botucatu, SP

The objective of the present paper was to study the structure of a semi-deciduous forest. The main purpose was to verify if the floristic composition and/or structure is influenced by the mosaic developmental phase. The study has been done in 200 plots, each one measuring 10 × 10 m, forming a grid of 200m × 100 m in the center of the forest fragment. In to separate the study area in units representing different phases of forest mosaic (gap, construction and mature), the plots were classified by cluster analysis based on structural traits. The species with the highest influence the community structure were Aspidosperma polyneuron, Trichilia claussenii and Trichilia catigua.Gap, construction and mature phases presented different patterns in spite of the three species influence.

Indicadores de floresta urbana a partir de imagens aéreas multiespectrais de alta resolução

The present work evaluated urban forest indicators, acquired through airborne high-resolution multiespectral images, on the quality of the urban design and its vegetative fraction, in special its trees, in nine neighborhoods of Piracicaba, SP. There were made supervised classifications for characterization of intra-urban elements and the proportions obtained, as exposed soil, tree cover, lawns, asphalt, concrete pavements and roofs. They were studied for the measurement of the urban forest in each place. These variables were related to each other, as well as with the independent variables: population density, people with more than fifteen years of study and family heads with income above twenty minimum wages, obtained through population census. Through the analysis of linear regression variables were identified for intra-urban areas evaluation. Correlations were made and linear regressions among the data obtained from the image and among the proposed indicators. Negative correlations were obtained among population density and arboreal covering and the evaluated indices, in accordance with the predicted in the literature. Composite indicators are proposed, as: the proportion between arboreous space on waterproof space (PAW) and the proportion between arboreous space on building space (PAB). It is concluded by the possibility of the use of those indicators for evaluation of the urban forest and definition of priorities in the execution of ordinances to the improvement of the urban forestry, being prioritized the application of resources in the most lacking neighborhoods.

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.

A frágil realidade de plástico: um estudo comparativo da imagem Casa de Bonecas em henrik ibsen e katherine mansfield

Considering the importance of significations in literary works, this paper proposes a comparative study of the image of the Doll's House in Henrik Ibsen's play ADoll's House (1879), and Katherine Mansfield's short story The Doll's House, published in the book The Dove's Nest (1923), based on the theories of Gaston Bachelard and Jean Baudrillard. In both cases, one notices that the presence of this image indicatesnot only the construction of these works' environment, but also a criticism of the bourgeois model of a perfect and flawless society, as the described image refers to. However, even though this image shares the same idea in both works, it will be explored differentlyin each case, whether through the search of Nora's character in escaping social conformity as in Ibsen, or through the subtle childlike game experienced by the Kelvey sisters, asin Mansfield.

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.

Correlação espacial do índice de vegetação (NDVI) de imagem Landsat/ETM+ com atributos do solo

The precision agriculture technologies such as the spatial variability of soil attributes have been widely studied mostly with sugarcane. Among these technologies have been recently highlighted the use of the vegetation index derived from remote sensing products, such as powerful tools indicating the development of vegetation. This study aimed to analyze the spatial variability of clay content, pH and phosphorus in an Oxisol in an area with sugarcane production, and correlate with the Normalized Difference Vegetation Index (NDVI). The georeferenced grid was created for the soil properties (clay, phosphorus and pH) and generated the maps of spatial variability. For these same sites were calculated the NDVI, in addition to mapping of this ratio, the evaluation of the spatial correlation between this and other studied properties. The clay and phosphorus content showed positive spatial correlation with the NDVI, while no spatial correlation was observed between NDVI and pH. The satellite images from the sensor ETM + Landsat were used to correlate to NDVI to observe the spatial variability of the studied attributes.

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.
