Callinectes ornatus tem sua distribuição geográfica no Atlântico ocidental: da Carolina do Norte até a Florida, golfo do México, Antilhas, Colômbia, Venezuela, Guiana e Brasil (Amapá ao Rio Grande ao Sul), ocorrendo em fundos de areia, lama e águas menos salinas podendo alcançar 75 metros de profundidade (Melo, 1996). Essa espécie tem um papel importante na teia trófica marinha, pois possui o habito carnívoro oportunista alimentando se também de detritos, assim controlando a estrutura de várias comunidades bentônicas (Haefner, 1990; Mantelatto & Christofoletti, 2001; Mantelatto et al., 2002). O presente estudo aborda as populações de C. ornatus que vivem no infralitoral não-consolidado das regiões das Ilhas do Mar Virado e das Couves, localizadas no litoral norte do Estado de São Paulo, e teve por objetivo a caracterização dos períodos de recrutamento e reprodutivos da espécie baseado na presença de jovens/adultos e fêmeas ovígeras respectivamente. Os dados utilizados nesse estudo foram coletados do Verão de 1998 á Primavera de 1999 no infralitoral não consolidado das Ilhas do Mar Virado e das Couves totalizando dois anos. As amostragens foram realizadas mensalmente, com auxilio de um barco de pesca equipado com duas redes do tipo “double-rig”. O total coletado durante os dois anos foi de 1164 animais. Os menores indivíduos machos e fêmeas encontrados na Ilha do Mar Virado apresentam os seguintes tamanhos respectivamente 22,2 mm e 17,7 mm, já na Ilha das Couves foram de 20,2 mm e de 32,3 mm. Foi obtido um total de 12 classes de tamanho, com 5,0 mm de amplitude. As duas primeiras classes foram ocupadas apenas por indivíduos jovens já as cinco ultimas principalmente por indivíduos adultos e fêmeas ovígeras. Para os indivíduos machos adultos foi possível observar o deslocamento de modas da Primavera de 1998 à Primavera de 1999... (Resumo completo, clicar acesso eletrônico abaixo)

Faced with the global discussion about the development of new alternative energy sources, this work tries to contribute to the understanding of the introduction of biodiesel in the energy market, identifying the barriers in the social logic, economic and productive in different spaces, rural and urban. Based on the guidelines of the National Biodiesel Production and Use Program (PNPB), it intended to accompany the implementation of public policies in relation to family farmers settled in the Pontal, located in the western region of São Paulo. In parallel, we will analyze the organizational structure and logistics of the production of biodiesel in the city, although it does not dependent on agricultural production and it is not a target of public policies, it takes advantage of the demand created by PNPB when it comes to increasing the amount of biodiesel blended with mineral origin diesel. The activity examined in the urban space is the collection of used frying oil held by Ecosanta Biofuels, a company located in the town of Maua, São Paulo metropolitan region. The monograph aims to broaden our understanding despite the urban-rural issue regarding the obstacles and opportunities in expanding renewable energy

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.

(Ant diversity (Hymenoptera) in a fragment of Semidecidual Seasonal Forest in Northwest of São Paulo State, Brazil). Due to scarce knowledge about ant fauna from Northwestern São Paulo State, the present study aimed to know the taxonomic diversity of Formicidae, relating the results to climatic variation along of one year. The samples were gotten monthly, using pitfall traps. It was sampled 25 species of 15 genera and seven subfamilies. Myrmicinae was the sampled richest subfamily, follows by Formicinae and Ponerinae. According Wilcoxon test, the species richness, equability and diversity estimated by Simpson index were significantly higher in the rain season. The obtained results suggest that the abundance of ants is significantly related to the temperature variation, while the ant assemblage structure is related to thermal and pluviometric variations.
