Soil texture spatial variability of different parent material in pereira barreto, São Paulo state

The variation of soil textural characteristics is a function of the relief and parent materials. The objective of this work was to study soil texture spatial variability from different parent material in Pereira Barreto, SP. An area of 530.67 hectares was mapped through the use of Global Positioning System receivers and obtaining of Digital Elevation Models. A set of 201 soil samples was collected from every seven hectares, at three depths: 0 - 0.25 m; 0.25 - 0.50 m; and 0.80 - 1.00 m. The amounts of sand, silt and clay were obtained by the pipette method and analyzed by both descriptive statistics and geostatistics. Soil textures varied as a function of parent materials and topography.

Folha de São Paulo: o diário oficial do grande irmão

This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position´s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de São Paulo-Metrô (line yellow 4). And the flying disaster involving the airbus of Transportes Aéreos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the São Paulo´s government, in the person of the politician actor José Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis Inácio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy

Flutuação populacional e análise faunística de Carabidae e Staphylinidae (Coleoptera) em Jaboticabal, São Paulo

In this study a population survey of Carabidae and Staphylinidae (Coleoptera) adults was carried out with the aim to analyze their populations through faunistic indexes and to determine the influence of temperature, relative humidity and rainfall. The study was conducted in two areas cultivated with soybean/corn under no-tillage and conventional tillage systems and adjacent to a forest fragment and a Pinus stand, respectively. Beetles were sampled by pitfall traps distributed in two 100-m transects. The fauna was characterized by diversity (H), evenness (J), abundance, dominance, frequency and constancy indexes. The influence of air temperature, relative humidity and rainfall was verified using stepwise regression. The carabids Abaris basistriatus Chaudoir, Odontochila nodicornis (Dejean) and Scarites sp. were classified as predominant species in both areas, while Selenophorus alternans Dejean only classified as predominant in the area under conventional tillage system, likewise for Megacephala sp. and Selenophorus seriatoporus Putz. in the no-tillage area. The predominant species showed just one population peak each year, usually observed from December to January. The pluvial precipitation influenced the occurrence of the carabids positively and significantly, with O. nodicornis and Megacephala sp. being the most demanding species in relation to the effect of humidity on their dispersal.

Fauna parasitária de peixes oriundos de pesque-pague do município de Franca, São Paulo, Brasil. I. Protozoários

The present work studied protozoan parasites of cultivated fishes (N = 433) from two feefishing farm situated in Franca, São Paulo, Brazil, during a period of April 1997 through March 1999. Specimens of piauçú Leporinus macrocephalus Garavello & Britski, 1988 (Anostomidae), pacu Piaractus mesopotamicus Holmberg, 1887 (Characidae) carp Cyprinus carpio Linnaeus, 1758 (Cyprinidae), Tillapia rendalli Boulenger, 1896 (Cichlidae), nile-tilapia Oreochromis niloticus Linnaeus, 1758 (Cichlidae), matrinxã Brycon cephalus Günther, 1869 (Characidae) and tambacu hybrid (male of P. mesopotamicus x female of Colossoma macropomum Cuvier, 1818) were collected. The fishes were parasitized with protozoans Ichthyophthirius multifiliis Fouquet, 1876 (Protozoa), Trichodina sp. and Piscinoodinium pillulare (Schaperclaus, 1954), Lom, 1981 (Protozoa). In the cold season (autumn and/or winter) all species of fish were infected with I. multifiliis. Higher susceptibility to Trichodina sp. was observed in L. macrocephalus, C. carpio and P. mesopotamicus compared to tambacu, B. cephalus, T. rendalli and 0. niloticus. It was not observed significant difference (P > 0.05) in the seasonal variation of Trichodina sp. and P. pillulare infection of all species. A great number of P. pillulare without significant difference (P > 0.05) was reported to L. macrocephalus, P. mesopotamicus and tambacu.

Piscinoodinium pillulare (Schäperclaus, 1954) Lom, 1981 (Dinoflagellida) infection in cultivated freshwater fish from the Northeast region of São Paulo State, Brazil: parasitological and pathological aspects

O Centro de Aqüicultura, Unesp, Jaboticabal, SP, Brasil, recebeu peixes para diagnose, os quais apresentavam aglomeração nas bordas dos viveiros e na entrada da água. Dos 194 casos diagnosticados, 53 apresentavam estruturas brancas circulares ou ovais, imóveis, medindo 162 mm de diâmetro, identificadas como o dinoflagelado Piscinoodinium pillulare. em 34 casos, os parasitos estavam presentes nas brânquias, em 2 casos, no corpo e em 9 casos, em ambos. Dos 53 casos observados, 31 eram o híbrido tambacu; 7, o Piaractus mesopotamicus; 6, o Colossoma macropomum; 5, o Leporinus macrocephalus; 3, o Oreochromis niloticus; e 1, o Prochilodus lineatus. Os peixes apresentaram aumento da produção de muco no corpo e nas brânquias e equimoses no pedúnculo caudal e nos opérculos. As brânquias também apresentaram palidez, congestão e petéquias. A histopatologia revelou a presença de grande número de trofontes situados entre as lamelas secundárias, fixados ou não ao epitélio. As lamelas primárias mostraram hemorragias intersticiais, severa hiperplasia do epitélio e das células caliciformes e infiltrado inflamatório. O presente trabalho é o primeiro relato de P. pillulare no Brasil e enfatiza a importância dos dinoflagelados, que causaram significativas perdas econômicas entre 1995 e 1997.

Fauna parasitária de peixes oriundos de pesque-pagues do município de Franca, São Paulo, Brasil. II. Metazoários

Metazoan fauna from cultivated fishes (N = 433) in two feefishing farm of Franca, State of São Paulo, Brazil, was studied during a period of April 1997 through March 1999. Specimens of piauçú Leporinus macrocephalus Garavello & Britski, 1988 (Anostomidae), pacu Piaractus mesopotamicus Holmberg, 1887 (Characidae), carp Cyprinus carpio Linnaeus, 1758 (Cyprinidae), Tillapia rendalli Boulenger, 1896 (Cichlidae), nile-tilapia Oreochromis niloticus Linnaeus, 1758 (Cichlidae), matrinxã Brycon cephalus Günther, 1869 (Characidae) and tambacu hybrid (male of P. mesopotamicus x female of Colossoma macropomum Cuvier, 1818) were collected. A total of 29.3% was parasitized by monogenean, 9.7% with crustacean (copepodits and adults of Lernaea cyprinacea Linnaeus, 1758 and Argulus sp.) and 1.6% with myxosporean (Henneguya piaractus Martins & Souza, 1997 and Myxobolus colossomatis Moinar & Békési, 1993).The most susceptible species to myxosporean infestation was P. mesopotamicus. L. macrocephalus and P. mesopotamicus that showed a higher susceptibility to Argulus sp infestation. It was not observed significant difference (P > 0.05) in the seasonal variation of L. cyprinacea infection of all species. L. macrocephalus, P. mesopotamicus and tambacu showed a great number of P. pillulare with no significant difference (P > 0.05) between them. Monogenean infections were observed in all examined species, without significant difference (P > 0.05) in the seasonal variation. Nevertheless, occurrence of monogenean was higher in P. mesopotamicus and lower in Nile-tilapia. By the other hand, parasites number collected from P. mesopotamicus was lower in the winter. Copepodits of L. cyprinacea were found in the gills of P. mesopotamicus, tambacu and L. macrocephalus. However, adults of L. cyprinacea were observed only in the P. mesopotamicus and tambacu.

Qualidade da água de nascentes com diferentes usos do solo na bacia hidrográfica do córrego rico, São Paulo, Brasil

Com o objetivo de verificar a influência de remanescentes de vegetação ciliar e da ação antrópica na qualidade da água, estudaram-se quatro nascentes, sendo duas com a presença de vegetação natural remanescente e duas com predominância de atividades agrícolas. Essas nascentes fazem parte da bacia hidrográfica do Córrego Rico, estando localizadas nos municípios de Taquaritinga e de Guariba - SP, em duas classes de solo: Argissolo e Latossolo, respectivamente. Definiram-se pontos de coleta da água nas nascentes e ao longo dos cursos d'água (entre 0 a 50 m da nascente), em dois períodos (chuvoso e seco). Foram analisadas as seguintes variáveis: cor, pH, temperatura, turbidez, alcalinidade, dureza total, dureza em magnésio, dureza em cálcio, fósforo, nitrogênio e demanda bioquímica de oxigênio. de maneira geral, ocorreu agrupamento por nascentes e também por períodos, confirmando que os períodos de amostragem, assim como as características e diferentes usos do solo influenciam na qualidade da água das microbacias. As variáveis cor, turbidez, alcalinidade e nitrogênio total foram as que apresentaram maior importância relativa nas variáveis canônicas.

Qualidade e maturação de tangerinas e seus híbridos em São Paulo

A ampliação da oferta de tangerinas tanto no mercado interno como no externo é limitada pela grande quantidade de sementes nos frutos das principais cultivares, danos na casca resultante de doenças e pela pequena produção nas épocas mais quentes do ano. O presente trabalho teve como objetivo caracterizar a qualidade dos frutos e a época de maturação de 46 tangerinas e híbridos em condições de campo na Estação Experimental de Citricultura de Bebedouro (EECB), Bebedouro-SP. As variedades de tangerinas e híbridos (tangores e tangelos) foram introduzidas de bancos de germoplasma da Itália, Portugal, Espanha e França, e a pesquisa desenvolveu-se durante os anos agrícolas de 2001/2002 e 2002/2003. Foram avaliadas características externas de qualidade, como altura e diâmetro dos frutos, massa dos frutos, facilidade em descascar com a mão e características internas como: número de sementes, teor de sólidos solúveis totais, acidez total titulável, rendimento em suco, ratio e rendimento em polpa. Duas cultivares apresentaram frutos de boa qualidade e época de maturação precoce, podendo ser disponibilizadas no mercado, num período de escassez deste tipo de citros, e serem alternativas à tangerina-'Cravo'. Quatro cultivares que apresentaram boa qualidade e maturação mediana poderão ser alternativas à 'Poncã'.
