Detecção de prováveis deformações neotectônicas no Vale do Rio do Peixe, Região Ocidental Paulista, mediante aplicaçao de Índices RDE (Relac̈ão Declividade-Extensão) em segmentos de drenagem

Running water is one of the most important of all the physical processes which fashion the landscape, allowing gravity to operate along the valley floors. Besides this, the streams show a fast adjustment to the crustal deformations, even to the most gentle ones. This geologic behavior turns them a potential tool for neotectonic studies, specially the analysis of morphotnetric parameters associated with hydraulic gradient and discharge, this second factor being directly proportional to the extension of the streams. Both elements, gradient and stream length, can be combined in the SL index. The purpose of this paper is to show the RDE index application in the neotectonics analysis of the Rio do Peixe hydrographic basin and to compare the obtained values with the geologic basement incised by the streams. This basement encompasses Cretaceous sedimentary rocks of post-Serra Oeral Formation magmatism (Caiuá and Bauru groups) and Quaternary deposits that include chiefly recent alluvial plains and some Pleistocene terrace deposits. In the final part of this paper, an attempt is made in order to correlate the RDE results and the neotectonic framework admitted to this portion of the São Paulo State territory, as well as with field geologic, seismologic and paleoseismologic known elements. The results indicate the presence of two groups of anomalies: The first set corresponds to the Marília-Exaporã Plateau border, and the second one, located in the central portion of the hydrographic basin, is correlated to the Presidente Prudente seimogenic zone.

Metodologia para quantificação de leucóciotos totais em peixe Oreochromis Niloticus

Haematological investigation is an important part of disease diagnosis. The techniques used for mammals are generally applicable for fishes with slight modification. The presence of nucleated erythrocytes and thrombocytes in fish may cause some confusion in the identification of blood cells, mainly in total leukocytes count. This work evaluated two different methods (direct and indirect) of leukocytes counting. Specimens of tilapia were divided randomly into four groups of 48 fish each. Each group was further randomized into three replicate experiments of 16 fish per replicate in 40 L aquarium and maintained for 10 days. Counting of leukocytes in peripheral blood was determined in six fishes per group at the times: 0, 3, 7 and 10 days. The direct method in Neubauer chamber showed a large dispersion of data in regard to the average, the opposite was observed in indirect method determined in blood smears that showed more homogeneity among groups. Due to this factor the indirect method can be considered more accurate than the direct method for counting leukocytes in fishes.

O uso da silagem de subprodutos da filetagem de peixe na alimentação de suínos em crescimento - parâmetros séricos

The study was carried out to evaluate the inclusion of increasing levels (0, 3,0 and 6.0%) of fish silage (SSFP), in the ration. The parameters studied were urea, uric acid, total protein, triglycerides, total cholesterol and lipoproteins (LDL, HDL and VLDL). Eighteen female piglets Moura weighting and crossbred Duroc x Moura, were used with 24,0± 3,0 kg in average weight and 90 days of age and eighteen male pigs Moura and crossbred Duroc x Moura, with 31,5±5,0 kg in average weight and 70 days of age in a randomized design with 3 treatments. The results showed no effect to the addition up to 6,0% of SSPF in the swine diet neither for in growth, nor to the serum parameters, even if had been found alteratum on the urea plasmatic concentrations experiments. All the parameters was closed to the normal value recommended in the literature.

One specimen of the lophiid white anglerfish, Lophiodes beroe was collected for the second time in Brazilian waters, which far extends the limit distribution of the species to southeastern region (25°00'08).

Efeito de hidrolisado de peixe sobre o crescimento micelial e controle de Cylindrocladium spathiphylli em espatifilo

Fish hydrolyzed (HP), poultry manure (CF), shrimp skin (CC), cattle manure (EB), sewage sludge (LE) and castorbean presscake (TM) were evaluated for their effect of aqueous extracts with and without autoclaving, on mycelial growth and conidial germination of Cylindrocladium spathiphylli. The effect of mixtures of residues with potting mixes and their volatile compounds were also evaluated on the mycelial growth of the pathogen. To evaluate the effect of HP in the suppressiveness to Cylindrocladium spathiphylli, HP was added in potting mix artificially infested, at concentrations of 0, 10, 20, 30, 40 and 50% of the volume of water required to reach the water retention capacity of the potting mix. The mixtures were incubated for 10 days and transferred to pots containing one plug of Spathiphyllum Opal per pot. In the experiments in vitro, aqueous extracts and mixtures containing HP showed the highest suppressiveness against the pathogen. In the Spathiphyllum growing, the suppressiveness occurred at concentrations higher than 20% of fish hidrolyzed.

Histologia e histoquímica do intestino anterior de tilápia do Nilo (Oreochromis niloticus) alimentadas com dietas contendo silagem de peixe

This work was carried out to evaluate the action of the fermented fish silage and fish meal in the histochemical of the middle intestine of O. niloticus. A great epithelium intestinal was present in fishes fed with fish silage, independent of the animal origin protein proportions in diets. It was observed that the variation of the goblet cells secretion glicoproteic intensity is linked directly to the diet supplied to animals. The middle intestine of Oreochromis niloticus showed differences in the neutral mucus glicoproteic, acid glicoproteic and glicoconjugated secretion pattern, depending on the protein origin and the percentage used in the diet, demonstrating that this species can adapt its secretion system for the protection of the digesting apparatus during the absorption of different protein sources.

Henneguya nagelii n. sp. (Myxozoa: Myxobolidae) in Cyphocharax nagelii (Steindachner, 1881) (Teleostei: Characiformes: Curimatidae) from the Peixe's River, São Paulo State, Brazil

A new species of Myxosporea, Henneguya nagelii n. sp., is described parasitizing the gills of Cyphocharax nagelii collected from Peixe's River, São Paulo State, Brazil. Among the fish examined, 16.7 % had gills parasitized by myxosporeans. The plasmodia were white, round, or oval and measured 150-250 μm. The mature spores were fusiform and had smooth wall. The spores measurements were the following: total length, 34.5 ± 4.2 (26.4-39.9) μm; body length, 12.0 ± 0.5 (11.2-11.9) μm; body width, 4.9 ± 0.3 (4.4-5.5) μm; and caudal process length, 22.4 ± 4.0 (14.7-27.3) μm. The polar capsules were elongated and of unequal size, with lengths of 4.9 ± 0.4 (4.0-5.9) μm and 5.2 ± 0.4 (4.6-6.0) μm for the longest and shortest axes, respectively. Capsule width was 1.8 ± 0.2 (1.5-2.2) μm. Each capsule contained a polar filament with six to eight turns. There was no mucous envelope or iodinophilous vacuole. Morphometric differences between this parasite and other species of the genus Henneguya indicated that the parasite observed in C. nagelii is a new species. This is the first species of Myxosporea described in Peixe's River. © 2013 Springer-Verlag Berlin Heidelberg.
