Haddadus binotatus é uma espécie endêmica de Mata Atlântica e ocorre desde o sul de Pernambuco até o Rio Grande do Sul. Apesar da sua ampla distribuição pouco se conhece da história natural dessa espécie. Haddadus binotatus apresenta desenvolvimento direto e ovos são depositados sob a serapilheira ou sob troncos caídos. Há dimorfismo sexual, sendo as fêmeas maiores do que os machos. O objetivo desse estudo é conhecer os padrões reprodutivos de populações de H. binotatus no continente e em ilhas do litoral do estado de São Paulo. Os objetivos específicos são: 1) avaliar as diferenças morfológicas entre populações de H. binotatus entre ilhas e entre ilhas-continente, 2) avaliar se há dimorfismo sexual em cada população, e 3) comparar os padrões reprodutivos entre populações insulares e continentais. Neste estudo, foram utilizados exemplares de H. binotatus, depositados na coleção de Anfíbios (CFBH), do departamento de Zoologia, Instituto de Biociências, UNESP, Campus de Rio Claro. Os exemplares são provenientes de uma localidade no continente (São Sebastião) e três ilhas (Couves, Queimada Grande e Ilhabela). Os exemplares provenientes das ilhas, com exceção daqueles da Ilha das Couves, foram maiores do que os da Juréia. Houve dimorfismo sexual em todas as populações, sendo as fêmeas maiores. As populações insulares apresentam número de ovócitos menor do que a população do continente (Juréia). O número de ovócitos semelhante aos da população da Juréia foi registrado para uma população em Minas Gerais, reforçando o padrão de que populações insulares têm desovas menores. No entanto, não houve diferença no tamanho dos ovos. As diferenças encontradas para as populações insulares podem ser resultado de recursos mais limitados como espaço e alimento, pelo tamanho das presas e/ou ausência de predadores. Este estudo preliminar representa... (Resumo completo, clicar acesso eletrônico abaixo)

In recent years the development based on a pattern of production and consumption in large-scale, established relations with degrading the environment, jeopardizing the availability of natural resources. From then on, it became necessary to integrate the environmental dimension to the other planning issues, appearing then the Environmental Planning. The objective of the Environmental Planning generally defined by society, aims help in making decisions; subsidized by a diagnosis at the same time identify and define objectives more environmentally suitable to assist in developing public policy. Thus, the development of prospective scenarios together by experts and stakeholders assists in public policy development and decision-making. In 2007, seeking to structure environmental management in the State, the Department of the Environment of São Paulo has created 21 Strategic Environmental Projects, including the project Cenários Ambientais 2020 with the goal of developing public policy proposals for medium and long term from prospective environmental scenarios. This paper reviews the methodologies used in constructing the scenarios in this project; sought to evaluate the construction process according to what is proposed by Alcamo and Henrichs (2008); and investigated the context that encouraged the development of the project

This study aims to examine rural development in the State of São Paulo, comparing the administrative regions of Campinas, Registro, and São Jose dos Campos. In addition, it will be studied new concepts and new actors in rural Brazil together with actions and changes in the European Union regarding the rural development, as well as structural and social changes of the old dichotomy CITY COUNTRYSIDE

To verify the levels of concentration of some heavy metals in fishes from Sorocaba river (São Paulo, Brazil) and evaluate if this contamination offers health risks to the fishermen, 63 samples of fishes collected from four points along the river were studied for cadmium, lead, chromium, nickel and mercury, with emphasis in this last, since it is the most toxic and most probable as a fish contaminant. Analyzing muscle samples by cold vapor atomic absorption spectrometry it was shown that the fishes are not contaminated. None of the five metals studied were present in prohibitive level and the fishes could be judged secure for human consume. It was also analyzed data from four years of cadmium, lead, chromium, nickel and mercury monitoring made by CETESB, from 1997 to 2000, in water from the main rivers of the State of São Paulo. The study pointed out that the majority of the monitored rivers still present contamination by those metals in a level that requires an improvement of the pollution control actions.

"This paper aims to examine three regional development plans proposed for the region of the valleys of rivers Tietê and Paraná: Rail Project (ISCO, 1994), the Development Plan (CESP, 1996) and Máster Plan (ADTP, 1996). The interest in conducting the study relies on the possibility that it may contribute to the debate on the reshaping of public policy and style necessary to establish a new pattern of regional development in the country"

This study evaluated environmental impacts at Meio Creek watershed, Leme, Sao Paulo, Brazil. A simplified environmental analysis index was applied correlating land use and occupation (vegetation elimination or modification, wildlife, color, smell, grease, oils, foams, larvae and red worms) with water quality parameters (conductivity, dissolved oxygen, pH and temperature). The simplified environmental analysis index showed that 27.8% visited places had a high or worrying environmental impact and 5.6% had a really high impact. As to the results of physical and chemical parameters, pH and conductivity values showed the conditions and standards that water Class 2 and 3 should have. These parameters were not the same for dissolved oxygen levels at most of the analyzed points. Despite the current environmental legislation at federal, state and municipal levels, Leme city does not have an effective environmental plan to control and protect springs and Meio Creek watershed and its tributaries.

The objective of this study was to evaluate environmental impacts on the Ribeirão Preto basin in order to define the most degraded areas and their causes and to propose solutions and management strategies for them. An impacts indicator questionnaire was designed, that allowed us to establish a direct relationship between reactions achieved and environmental factors by attributing value to some impacting parameters obtained by simple visualization in the field. The questionnaire was applied at 22 points, based on the influence area of the sub-basin and variability in land use. It was determined that the main environmental impacts that affect the basin are in nature effluent wastewater released into water bodies, the disposal of waste and deforestation. These factors were mainly noticed near to Ribeirão Preto city (State of São Paulo), the most populated region. Such information provides subsidies necessary to environmental management in this basin to decreasing environmental degradation. Among the management strategies suggested, it is possible to highlight that related to the accomplishment of environmental legislation, recuperation of degraded areas and adequate treatment and disposal of effluents.
