The Brazilian campos rupestres (high-altitude grasslands) are very important on the world conservation scenario because of high species richness and endemism. These grasslands are regarded as threatened ecosystems due to intense, on-going disruption by man's activities. The aim of this study was to describe the reproductive and vegetative phenological patterns of six shrub species endemic to these grasslands in the Espinhaço Range, sympatric in Serra do Cipó, MG. We tested the relationship between species phenophases and local climate seasonality. We expect that the species phenophases are strongly correlated with variations of the dry and wet seasons. Observations were conducted monthly on reproductive (flowering, fruit production and dispersal) and vegetative (leaf fall and budding) phenophases. Given the combination of reproductive phenology, vegetative phenology, and seasonality, we observed four phenological strategies for the six species. Therefore this study revealed great diversity in phenological patterns, even when considering the small number of species sampled. Moreover, all species showed a significant seasonal pattern for the reproductive phenophases, with high concentrations of species reproducing during a given season, suggesting a key role of climate in defining phenological patterns in the campo rupestre grasslands.

A pesquisa resgata o trecho paulista do “Caminho Novo”, antiga estrada geral de São Paulo, ligação terrestre com o Rio de Janeiro, a partir do século XVIII. No chamado Vale Histórico da Serra da Bocaina, cujo relevo se apresenta muito movimentado, a cultura do café penetrou em território paulista. Esta sub-região do Vale do Paraíba tornou-se uma das mais prósperas do país. A fase posterior, de queda na produção cafeeira, transformou-a numa região “deprimida” e estagnada. Atualmente, existem esforços para, através dos diversos ramos do turismo, reativar e dinamizar esta região vale-paraibana paulista, de modo a reintegrá-la ao pujante sistema econômico de São Paulo.

O objetivo deste trabalho foi apresentar os aspectos reprodutivos de Harttia carvalhoi, Miranda Ribeiro, 1939, um pequeno loricariídeo cuja distribuição é restrita a área de drenagem do rio Paraíba do Sul. Um total de 110 exemplares de H. carvalhoi foi obtido. O período reprodutivo acontece desde setembro até fevereiro. O tipo de desova foi identificado como total e a taxa de fecundidade variou de 16 a 106 ovócitos. Este tipo de estudo é importante, visto que fecundidade é uma característica específica e é uma adaptação às condições do ciclo de vida, variando com o crescimento, densidade populacional, alimentos disponíveis e taxa de mortalidade. Também foi enfatizada a importância deste estudo, pois não há estudos prévios sobre a reprodução desta espécie

The main purpose of this work is to evaluate the chemical composition of the groundwaters from Guarani Aquifer System and Serra Geral Aquifer System in the Rio Pardo basin, located at the southwestern of São Paulo state. To the hydrochemical characterization, physicalchemical analyses from 32 sampled wells were used. These results were plotted in Piper diagrams allowing the classification of groundwater as calcium or calcium-magnesium bicarbonate type and sodium bicarbonate type for both aquifer systems. Distribution of hydrochemical facies over the study area was obtained using Stiff diagrams. The groundwater can be classified, representing in this sequence its hydrochemical evolution. The recognized mechanisms responsible for groundwater evolution are dissolution of minerals magnesium, such as olivine, present in the basalt, dissolution of feldspars and removal of the carbonate cement of the sandstones mineral framework. Ionic exchange may represent an important processes in the groundwater evolution, responsible for the increase in the sodium concentration and decrease of calcium

Seeking the integrated management of water resources and financial compensation especially as a management tool, according to the Law No. 9433 of 1997 and No. 9985 of 2000. This research's main objective is measuring the flow contribution of Núcleo Santa Virginia, the State Park of Serra do Mar, starting from the hydrological regionalization method, developed by the Department of Water and Power. According to the Law 9985 of 2000 Conservation Units have the right to receive in the form of an investment a portion of the amount paid by Power Plants, being passed directly to the Conservation Units, differently from the 9433 Act. By dividing the area of Núcleo Santa Virgínia, in Sub-basins, it was possible to find the minimum flow during seven consecutive days, with a return period of ten years, Q7,10, and steady water flow in 95% of the time, Q95 for the Center and from these data to calculate the monetary value of law under Articles 47 and 48 from Law 9985 of 2000
