Governança ambiental e unidades de conservação do meio ambiente: uma abordagem institucionalista

Os esforços de conservação ambiental têm enfrentado muitos desafios, dentre os quais a dificuldade para implementar áreas protegidas. As evidências sugerem que a criação legal de uma área protegida não é condição suficiente para sua efetiva implementação. O presente trabalho adota uma abordagem institucionalista para entender as condições que poderiam levar ao sucesso ou ao fracasso de tais áreas. O arcabouço teórico é composto por trabalhos de Direito Ambiental, Biologia da Conservação e, principalmente, da Nova Economia Institucional. Inicialmente, busca-se reunir estes diversos campos do conhecimento sob um mesmo corpo de conhecimento, a Governança ambiental. Em seguida, formula-se uma hipótese de complementaridade institucional, i.e., a possibilidade de que exista sinergia na interação entre determinadas instituições. Esta discussão é utilizada para analisar a legislação brasileira referente às Unidades de Conservação. E, por fim, as hipóteses teóricas são examinadas em um estudo de caso da região de Mata Atlântica no Vale do Ribeira, São Paulo.

Uso do bivalve límnico Anodontites tenebricosus (LEA, 1834) no biomonitoramento de metais do Rio Ribeira de Iguape

This study investigated the contamination of the Ribeira de Iguape River - RIR by Cd, Zn, Cr and Pb, using the bivalve Anodontites tenebricosus as a biomonitor. Metal concentrations in tissue samples were measured by HR-ICPMS. Bivalve tissues exhibited mean levels of 1.00 µg/g Cd; 152.89 µg/g Zn; 14.79 µg/g Cr and 4.40 µg/g Pb. Lead concentrations were comparable to those reported for moderately contaminated sites. The results showed that Pb is bioavailable to the bivalves, exhibiting high concentrations and exceeding both natural and reference values for human consumption. The freshwater bivalve Anodontites tenebricosus is a suitable biomonitor of contamination by metals.

Space-temporal dynamics of limnological variables in a floodplain wetland located at Ribeira do Iguape Valley (São Paulo, Brazil) at different hydrological periods

AIM: The main goal of this research was to investigate the influence of the hydrological pulses on the space-temporal dynamics of physical and chemical variables in a wetland adjacent to Jacupiranguinha River (São Paulo, Brazil); METHODS: Eleven sampling points were distributed among the wetland, a tributary by its left side and the adjacent river. Four samplings were carried out, covering the rainy and the dry periods. Measures of pH, dissolved oxygen, electrical conductivity and redox potential were taken in regular intervals of the water column using a multiparametric probe. Water samples were collected for the nitrogen and total phosphorus analysis, as well as their dissolved fractions (dissolved inorganic phosphorus, total dissolved phosphorus, ammoniacal nitrogen and nitrate). Total alkalinity and suspended solids were also quantified; RESULTS: The Multivariate Analysis of Variance showed the influence of the seasonality on the variability of the investigated variables, while the Principal Component Analysis gave rise in two statistical significant axes, which delimited two groups representative of the rainy and dry periods. Hydrological pulses from Jacupiranguinha River, besides contributing to the inputs of nutrients and sediments during the period of connectivity, accounted for the decrease in spatial gradients in the wetland. This "homogenization effect" was evidenced by the Cluster Analysis. The research also showed an industrial raw effluent as the main point source of phosphorus to the Jacupiranguinha River and, indirectly, to the wetland; CONCLUSIONS: Therefore, considering the scarcity of information about the wetlands in the study area, this research, besides contributing to the understanding of the influence of hydrological pulses on the investigated environmental variables, showed the need for adoption of conservation policies of these ecosystems face the increase anthropic pressures that they have been submitted, which may result in lack of their ecological, social and economic functions.

Caracterização estrutural de substâncias húmicas aquáticas extraídas dos rios Itapanhaú e Ribeira de Iguape

The knowledge of the structure characteristic of the Organic Matter is important for the understanding of the natural process. In this context aquatic humic substances (principal fraction) were isolated from water sample collected from the two distinct rivers, using procedure recommended for International Humic Substances Society and characterized by elemental analysis, electron paramagnetic resonance and nuclear magnetic resonance (13C NMR). The results were interpreted using principal component analysis (PCA) and the statistical analyses showed different in the structural characteristics of the aquatic humic substances studied.

USING THE FRESHWATER BIVALVE Anodontites tenebricosus (LEA, 1834) AS A BIOMONITOR OF METALS IN THE RIBEIRA DE IGUAPE RIVER

USING THE FRESHWATER BIVALVE Anodontites tenebricosus (LEA, 1834) AS A BIOMONITOR OF METALS IN THE RIBEIRA DE IGUAPE RIVER. This study investigated the contamination of the Ribeira de Iguape River - RIR by Cd, Zn, Cr and Pb, using the bivalve Anodontites tenebrieosus as a biomonitor. Metal concentrations in tissue samples were measured by HR-ICPMS. Bivalve tissues exhibited mean levels of 1.00 mu g/g Cd: 152.89 mu g/g Zn; 14.79 mu g/g Cr and 4.40 mu g/g Pb. Lead concentrations were comparable to those reported for moderately contaminated sites. The results showed that Pb is bioavailable to the bivalves, exhibiting high concentrations and exceeding both natural and reference values for human consumption. The freshwater bivalve Anodontites tenebricosus is a suitable biomonitor of contamination by metals.
