The Cerrado (Brazil) plant cytogenetics database
Cerrado is a biodiversity hotspot that has lost ca. 50% of its original vegetation cover and hosts ca. 11,000 species belonging to 1,423 genera of phanerogams. For a fraction of those species some cytogenetic characteristics like chromosome numbers and C-value were available in databases, while other valuable information such as karyotype formula and banding patterns are missing. In order to in...
متن کاملPedology and plant physiognomies in the Cerrado, Brazil.
This study was carried out in Paraopeba National Reserve. It aims to classify and evaluate the soil of the studied area and to verify the influence of soil attributes on vegetation by testing the following hypotheses: 1) under woodland physiognomies (Cerradão) the soil fertility is higher and the Al content lower; 2) open savanna occurs only in areas with high Al contents. For this purpose, rep...
متن کاملTwenty years of post-fire plant succession in a "cerrado", São Carlos, SP, Brazil.
Secondary succession in degraded areas is little studied, especially where long-term observation of evolutionary processes is concerned. The aim of this work was to follow the qualitative and quantitative changes in vegetation throughout the regeneration process after fire in a cerrado with forest physionomy. The area under study is a reserve on CPPSE-EMBRAPA's farm, São Carlos region of São Pa...
متن کاملDistribution of periphytic algae in wetlands (Palm swamps, Cerrado), Brazil.
The distribution of periphytic algae communities depends on various factors such as type of substrate, level of disturbance, nutrient availability and light. According to the prediction that impacts of anthropogenic activity provide changes in environmental characteristics, making impacted Palm swamps related to environmental changes such as deforestation and higher loads of nutrients via alloc...
متن کاملBird communities in two fragments of Cerrado in Itirapina, Brazil.
The Cerrado domain is a mosaic of vegetation types at the local scale, and this environmental heterogeneity leads to high regional bird diversity. Therefore, we aimed to survey quantitative and qualitatively the bird fauna of two fragments of Cerrado and to compare them with an adjacent protected area (Estação Ecológica de Itirapina), in order to assess the heterogeneity of bird diversity in th...
