| This study was carried out with the aim of evaluating the spatial variation of the water quality in the Itajaí-Açú River estuary. Seven stations along the estuary were monitored on a weekly basis, from October 2003 to December 2004, plus two stations in tributaries (Itajaí-Mirim River, the main tributary, and one reference station). This monitoring included measurements of salinity, pH, dissolved oxygen, temperature, nutrients(NH+4,NO3-2,NO-3,PO3-4,H4SiO4) Biochemical Oxygen Demand (BOD), total phosphorous and dissolved organic phosphorus (TP and DOP), particulate organic carbon (POC), suspended particulate matter (SPM) and chlorophyll-a (Cla). Multivariate analyses demonstrated the compartmentalization of the system based on the deterioration in water... |

| A qualitative and quantitative analysis of the environmental damages occurrences was conducted through the lawful documents established for charging at the State Prosecution Service of São Carlos city, State of São Paulo, during 1991 - 2000, to understand the relationship between environmental problems and the current development actions. The environmental damage identified were grouped into nine classes, where deforestation was prevailing in each year along the period of study. Of the total number of deforestation occurrences, 180 was related to areas smaller than 5 ha. It corresponded to 110.35 ha of the total deforested area. The other 37 were associated with areas higher than 5 ha, equivalent to 1,013.27 ha. The registers of environmental damages in... |

| Environmental analysis and zoning were carried out for management purpose of the Longines Malinowski Municipal Park (LMMP). With an area of 24.85 ha, this urban park includes a patch of sub-tropical humid forest, completely surrounded by residential and commercial areas in the City of Erechim, Rio Grande do Sul State,Brazil. Landscape features derived from aerophotogrametric maps, based on the use of Geographical Information Systems (GIS-IDRISI), resulted in several thematic maps, through which a proposal of environmental zoning was perfomed, observing the definition of five zones of use. The environmental diagnosis identified several types of activities potentially harmful to the biodiversity of the LMMP and city's environmental quality. The... |

| Analysis of the distribution of biogenic gases in the floodplain of the Mogi-Guaçu River (São Paulo, Brazil) enabled the establishment of a "redox hierarchy", in which the main channel was the most oxidizing environment, followed by Diogo Lake, with Infernão Lake having the most reducing conditions of the subsystems evaluated. Diogo Lake exported about 853.4 g C.m-2.year-1, of which, 14.6% was generated from methanogenesis and 36.7% by aerobic respiration. For Infernão Lake, these values were 2016 g C.m-2.year-1, 1.8 % and 41.5 %, respectively. Carbon export by these systems was predominantly in the form of CO2, which was responsible for the release of 728.78 g C.m-2.year-1 at Diogo Lake and 1979.72 g C.m-2. year-1 at Infernão Lake. Such patterns may... |

| ABSTRACT An environmental zoning proposal due to the demand to develop strategies to ensure biodiversity scenarios for the remaining mixed ombrophilous forests was carried out for the Irati National Forest, a legally protected area for sustainable use located in southern Brazil. To identify land use and cover, Ikonos PSM images dated from December 2004, based on the interpretation of visual character and vectorization of orbital data were used. Qualitative and quantitative classifications identified six types of land and cover use: native forest, forestry, capoeira grass, wetland, araucaria plantation, and anthropic. The native forest relative to the mixed ombrophilous forest was the prevailing type of land cover. The environmental zoning proposal defined... |

| Neste trabalho foram empregadas 25 parcelas permanentes de 10 m × 25 m e amostrada a vegetação com DAS (Diâmetro à Altura do Solo) igual e superior a 1,0 cm. Em uma área de 0,625 ha foram amostrados 8.454 ind.ha-1, 121 espécies, 74 gêneros e 42 famílias. As espécies de maior IVI foram Ocotea corymbosa (Meissn.) Mez, Pterodon pubescens Benth. e Xylopia aromatica (Lam.) Mart. Os altos valores de PSoR e de IVIA mostraram que O. corymbosa e P. pubescens estão representadas nos três estratos da comunidade, embora essas espécies predominem no estrato superior. O índice de Shannon mostrou alta diversidade florística (H' = 3,47 nat.ind.-1) e o índice de eqüabilidade (J' = 0,40) indicou dominância de P. pubescens e O. corymbosa na área. As distribuições diamétrica... |
