Bauru: terra de cerrado ou floresta?

Bauru: region of cerrado ou forest? The city of Bauru is located in São Paulo State, where the maps showing native vegetation distribution does not clearly defi ne its nature. In order to clarify which types of native vegetation was found in this region, a bibliographic survey was performed, ranging from ancient documents prepared by naturalists describing this region and recent research results of floristic and phytosociological character. It is concluded that in Bauru, semideciduous seasonal forests overlays the northwestern and that cerrado comes over the southeast region. In riparian areas where the cerrado prevailed, there are still traces of swamp forests and swamp grasslands. In the border areas between forests and cerrado, the occurrence of vegetation transition is common, with two distinct types of it and other typical of these ecotone zones.

Balanço de energia de fluxo de CO2: cerrado da floresta estadual de Assis

Based on climatological data and energy flow, this paper analyzes the behavior observed in microclimatic an important remnant of cerrado in the São Paulo State. The seasonal climate is well marked, in the study area, with two climatic periods (one dry and one wet). The vegetation presents physiology as a function of water availability and the local thermal conditions and can be seen marked changes in the landscape due to the more or less presence of solar radiation. It’s important to understand the ecosystems behave in the context of global change. It has gained the attention of many researchers in the world.

Estado nutricional de mudas de baru (Dipteryx alata) em área de recuperação e remanescentes de cerrado

The Dipteryx alata is a tree specie with possibility of use in human and animal nutrition, and in the pharmaceutical industry. For reclamation of degraded areas, the revegetation has been an alternative, however, requires fertilizer addition. The objectives of this study were to evaluate the nutritional status and growth of Dipteryx alata seedlings, introduced in degraded soil under recovery process, with residues (organic and agroindustrial), compared to collected seedlings in preserved Cerrado, and evaluate the residues impact on soil chemical properties. In this work the degraded soil received the incorporation of residues, organic - RO (macrophytes) and agroindustrial - RA (ash derived from burning bagasse from sugarcane), with the following doses: 0, 16 and 32 t ha- 1 and 0, 15, 30 and 45 t ha-1 respectively. Within three months of incorporation of residues into the degraded soil, the D. alata seedlings were introduced in the experimental area, and 12 months later were evaluated for height, stem diameter, chlorophyll content and leaf contents of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn. For purposes of comparison, the foliar concentration of those elements was determined in Dipteryx alata seedlings collected in preserved Cerrado area. Concomitant with the collect of leaves, at Cerrado and experimental area, soil was collected (0.0 - 0.20m deep) for evaluation of chemical parameters (P, OM, pH, K, Ca, Mg, H + Al, Al, Cu, Fe, Mn and Zn). Comparing the seedlings collected in the Cerrado with the seedlings from experimental area it is observed that the leaf concentration of N, P, K and Mg was higher in seedlings from preserved Cerrado in relation to those introduced in the experimental area. Fe, Mn and Zn, have lower foliar concentration in plants collected in the Cerrado, in the case of Mn the worst results occur in the absence of macrophytes indicating the importance of organic residue. The foliar concentration of Ca, S and Cu was similar in...

Assessing the dynamic of structural changes in Cerrado vegetation of protected and non-protected areas using NDVI

The structure of Brazilian savannah, named locally as “cerrado”, tends to change if the human pressures, such as pasture and intensive fire, are suppressed showing a densification of the physiognomies throughout the time. Vegetation Index acquired from remotely sensed data has been a proper way to study and monitoring large areas, and the Normalized Difference Vegetation Index (NDVI) is one of the most used for this purpose. The aim of this study was to assess the dynamic of structural changes in protected and non-protected areas of cerrado vegetation using NDVI. For this purpose, three cerrado fragments in the state of São Paulo, Brazil, were evaluated for a 26 year time span from 1985 and 2011, being two of them protected against anthropogenic interference. Landsat 5 –Thematic Mapper images were used and processed in ArcGIS. In the protected areas NDVI indicated that the vegetation followed the expected trend of changes for cerrado, with more open physiognomies tending to be denser throughout this period of 26 years, whereas in the non-protected fragment the NDVI evidences human pressure, showing lower phytomass in 2011. NDVI showed to be efficient in detecting and monitoring changes in cerrado vegetation structure, and can be useful to study both, the natural dynamics of cerrado vegetation and the anthropogenic interference in protected areas.

Avaliação in vitro da eficácia de extratos de plantas medicinais do Cerrado frente Staphylococcus aureos isolado de difetentes fontes de propriedades leiteiras

The objective of this study is to evaluate the potencial microbial activity in-vitro from the extract of some endemic plants from Cerrado such as Baccharis dracunculifolia, Cochlospermum regium, Croton antisyphiliticus, Eugenia dysenterica and Lippia sidoides, against the agent Staphylococcus aureus isolated from bovine mastitic milk, osteo from cow’s teat, milker equipament, nasal cavitites and milker’s gullet. The extracts were prepared from aerial parts as well as the reticular systems of plants using the solvents methanol, hexane and chloroform at a concentration of 10%. To evaluate the antimicrobial activity, the technique of microdilution in broth was used for determining the Minimal Inibitory Concentration (MIC) followed by the determination of Minimal Bactericidal Concentration (MBC). The extracts from Baccharis dracunculifolia and Croton antisyphiliticus, followed by extracts from Lippia sidoides, reported respectively, presented better inhibitory activity against the multiplication of the bacteria Staphylococcus aureus. Furthermore, the results demonstrate that the isolated strains from the milk and nasal cavities of the milker showed strong resistance against gentamicin, active agent commonly applied to combat mastitis bovine. However, there was sensitivity against extracts from the reported plants, reinforcing the importance of the medicinal plants as a therapeutic resource and its aplicability.
