Raias da espécie Narcine brasiliensis são frequentemente encontradas em regiões de substrato arenoso e lodoso localizadas entre o sudeste do Brasil e norte da Argentina, entretanto, há poucos estudos sobre seu ciclo de vida, assim como aspectos de sua distribuição e abundância. Verificar suas medidas corporais torna-se crucial para tais estudos, principalmente quando estes estão relacionados ao crescimento, maturação, comprimento máximo e estrutura populacional de elasmobrânquios. O presente estudo teve como objetivo analisar a ocorrência, a morfometria e o crescimento relativo da espécie no litoral do estado de São Paulo. Sendo assim, foram tomadas e avaliadas 46 medidas morfométricas corporais. Para verificar se havia diferenças significativas das proporções corpóreas entre machos e fêmeas, foi aplicado o teste “t de Student” e o teste de “Wilcoxon Rank”, conforme a distribuição da normalidade dos dados. Para avaliar a relação entre os caracteres morfométricos durante o crescimento dos indivíduos, foram ajustadas regressões lineares entre o logaritmo do comprimento total e o logaritmo de cada uma das variáveis, estimando-se o coeficiente alométrico (b); sendo b=1 (isometria), b>1 (alometria positiva) e b<1 (alometria negativa). Por último, foi verificado se havia diferença significativa do coeficiente alométrico (b) entre machos e fêmeas por meio de uma análise de covariância. A amostra analisada foi composta por 72 fêmeas de 237 a 470 mm e 33 machos de 236 a 380 mm. Os indivíduos foram capturados em substrato arenoso, sendo que não estiveram presentes indivíduos neonatos provavelmente pelo local de captura e seletividade da rede. Diferenças significativas foram encontradas na comparação das proporções corpóreas de machos e fêmeas, exceto para a região do espiráculo. As regressões lineares das variáveis logaritmizadas mostraram presença de isometria em 39,5%, alometria positiva em ...

Natural history studies aim to know where the organisms live, what they do, and their relationships within the environment, including the other organisms. The anurans, among other vertebrates, exhibits the greatest variety of reproductive modes as well as a high complexity of social organization, that may enable a lot of naturalist studies. Anurans modes of organization are direct related to parental care, vocalization of chorus organization, and with males territoriality. In general, the social organization is influenced by species reproductive pattern. This study aim to get information about the natural history of Hypsiboas albopunctatus (perereca-cabrinha) a species of the family Hylidae, on the region of Rio Claro Municipality, São Paulo State, Brazil. The major aspects discussed were: seasonality, spatial distribution, acoustic and visual communication, reproductive mode, reproductive site, abiotic factors influences, territoriality, courtship behaviour, satellite male behavior, embrace and defensive behavior. To obtain this data, nocturnal field excursions were realized monthly. Two sites of Rio Claro county where chosen as studies sites, the sítio Cantaclaro (22o19’36’’S; 47o42’57’’O), on the District of Itapé and Floresta Estadual Edmundo Navarro de Andrade (FEENA) (22o24’58’’S; 47o31’26’’O).

A produção de alimentos orgânicos no Brasil vem aumentando de maneira expressiva e tende a crescer ainda mais nos próximos anos, visto que a regulamentação da agricultura orgânica e seu marco legal são muito recentes. Considerando-se os problemas relacionados à agricultura convencional e o papel que a agricultura orgânica assume como alternativa ao sistema de produção vigente, o presente estudo tem como objetivo principal realizar uma revisão bibliográfica sobre a sustentabilidade do sistema orgânico de produção em seus aspectos técnicos, ecológicos, econômicos, socioculturais e políticos, comparativamente ao sistema de produção convencional. Além disso, buscou-se traçar um panorama atualizado sobre o mercado e a produção de alimentos orgânicos no Brasil e no Estado de São Paulo, de maneira a evidenciar os principais entraves à expansão da agricultura orgânica no país, enfocando especialmente os processos de certificação.

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.

Athletics in most of its history, turned to competition, giving it little pedagogical knowledge, prevailing knowledge grounded in records, indexes and competitions. Thus, although it is considered a classic content of Physical Education, this modality is still not widespread in schools. The present study aimed to investigate possible progress in the teaching and learning of athletics in the State Schools of Bauru from the implementation of the Curriculum of the State of São Paulo for Teaching Physical Education. We attempted to checking the perspective of teachers and students, the changes in teaching and learning as well as difficulties encountered from the deployment. To that end, we conducted survey of the theoretical and practical alternatives developed by Physical Education teachers, about athletics theme, since the implementation of the Curriculum of the State of São Paulo for the Teaching of Physical Education in 2008, in seven (7) state schools in Bauru-Sao Paulo, randomly chosen, prioritizing different regions of the county. There was the purpose of investigating, through questionnaires, interviews (applied to teachers and students), what progress has been achieved with regard to the approach of collegiate athletics in the teaching/learning process, if there are difficulties, what are these and how they could be addressed in order to improve teaching and learning in school athletics. The collected data were analyzed comparatively, before and after implementation of the Curriculum of the State of São Paulo for Physical Education, gathering and specifying negative and/or positive aspects raised by teachers and students. It was concluded that the students' knowledge of the sport has increased, but the practice of sport is still far from being normal to them, doing so is necessary to include content from the earliest school years. Teachers attribute the greatest difficulties to lack of infrastructure and materials suitable for this...

This article presents the historical trajectory of agricultural technical education in the State of São Paulo, 1882-2001, with emphasis on regulatory and policy aspects of transition management agencies and disruption in the construction and consolidation of a pedagogical and curricular design of this area of teaching technical and institutional policies of these technical schools. Thus focuses on the major changes in the political-normative and pedagogical and organizational character that shaped the construction of its especificidade.Isto because it is necessary to know the history of technical education 'agricultural' (agricultural area) in order to support the analysis of its configuration current and devise new prospects for your gestão.O Paulista agricultural education was subject to constant political uncertainties as to its principles and fins.As several transfers and reallocations it has undergone through different State Secretariats, reveal political barriers regarding its management and the difficulty of situating it in an appropriate and befitting their purposes locus.
