Organisation of the benthic macroinvertebrate assemblage in tropical streams of different orders in North-Eastern Brazil
Provedor de dados: 67
Autores: Gomes Pio,Jéssica F; da Silva Pereira,Tiago; Calor,Adolfo R; Copatti,Carlos E.
We selected streams located in north-eastern Brazil with the objective of assessing the effect of streams of different orders (1st, 2nd, 3rd) on the distribution and composition of benthic macroinvertebrates in the rainy and dry seasons. A total of 12822 individuals and 62 taxa of benthic macroinvertebrates were obtained, of which Chironomidae was the taxon with the most individuals (60.08% of the total). The benthic macroinvertebrate assemblage ordination demonstrated that streams of the 3rd order had a different assemblage structure compared to streams of the 1st and 2nd order. This distinction may be the result of taxa substitution. The benthic macroinvertebrate assemblage structure was correlated with environmental variables. In conclusion, the...

Evaluation of an ant sampling protocol (Hymenoptera: Formicidae) in three modified environments located inside an austral Atlantic Forest area of Brazil
Provedor de dados: 67
Autores: Lutinski,Junir Antonio; Lutinski,Cladis Juliana; Iop,Samanta; Mello Garcia,Flávio Roberto.
This study evaluated the efficiency as a tool for ant survey of a sampling protocol composed of six methods, and examined the role of environmental features on the efficiency of methods complementarity . We applied them in three environments (pine, eucalyptus and native forest) in the National Forest of Chapecó and the effect of the characteristics of these environments on methods complementarity. The sampling methods were pitfall traps, two types of bait (sardines and glucose), sweep net, entomological umbrella and Malaise trap. The protocol efficiency of the protocol in the ant inventory was evaluated based on rarefaction curves, richness estimators and records of occurrence of ants. The protocol captured the greatest richness on native forest...

Incorporation of dietary fatty acid in European sea bass (Dicentrarchus labrax) -  A methodological approach evidencing losses of highly unsaturated fatty acids
Provedor de dados: 5
Autores: Robin, Jean; Skalli, A.
A quantitative approach is presented to evaluate fatty acid incorporation in fish. Fatty acid composition of European sea bass juvenile was studied during an experiment using 6 isoproteic (54%) and isolipidic (18%) diets containing 0.23, 0.56, 0.72, 0.86, 1.01 and 1.86% DM n-3 highly unsaturated fatty acids (n-3 HUFA). Whole body fatty acid compositions were studied at the beginning and after 52 and 81 days feeding, fatty acid profiles evolved during time under dietary influences. Incorporations of individual fatty acids into total lipids were calculated as increases in individual fatty acids as percentages of the increase in total fatty acids during growth, on a per animal basis. Relative incorporations (RI) so defined generated similar profiles for the...

L'huître creuse Crassostrea gigas en Bretagne. Etude pilote en 1989 pour l'élaboration d'un réseau de données en biochimie, croissance, mortalité et pathologie de l'huître creuse sur huit sites conchylicoles bretons
Provedor de dados: 5
Autores: Le Bec, Claude.
Depuis son introduction en Bretagne, au début des années 70, peu d'études ont été consacrées à l'huître creuse Crassostrea gigas sur cette région, sauf lors de pollutions (Amoco Cadis) ou d'anomalies de croissance de la coquille. En l'absence de données récentes, des stations expérimentales "d'élevage" ont été mises en place sur 8 sites conchylicoles bretons. Un lot d'huîtres de "18 mois" est réparti en début d'année dans 96 poches, à raison de 6 poches par station et 2 stations par site. Des mesures de biométrie, de composition de la chair, d'lindex de qualité, de taux de survie, et de parasitisme sont réalisées après 7 mois d'élevage. Après étude des résultats variable par variable, une analyse descriptive par A.C.P. montre 6 groupes de sites ou stations...

Composition and microstructure of magma bodies from effective medium theory
Provedor de dados: 5
Autores: Taylor, Maj; Singh, Sc.
The extent and seismic properties of magma bodies beneath the subsurface are normally ascertained via seismic methods. The seismic properties of such bodies depend on the composition and microstructure of both melt and crystals. Using effective medium theory, we assess the effect of microstructure, geometry and orientation of melt and crystals on the seismic properties, namely P- and S-wave velocities and anisotropy. We find that S-wave velocity and anisotropy are key observables in determining the composition and microstructure of magma bodies.

What shapes amino acid and sugar composition in Mediterranean floral nectars?
Provedor de dados: 16
Autores: Petanidou, T.; Van Laere, A.; Ellis, W.; Smets, E.
We studied the amino acid (AA) composition of the floral nectars of 73 plant species occurring in a phryganic (East Mediterranean garrigue) community and investigated whether AA and sugar composition is shaped by evolutionary (plant phylogeny), ecological (flowering time as a direct effect of summer drought) and coevolutionary (pollinator partnership) constraints. Our study utilised an extensive plantpollinator matrix compiled in the same area where the plants had been sampled.  Using HPLC we detected 22 AA compounds/groups of compounds, out of which 15 were commonly present in almost all nectars. Among all AAs, phenylalanine was the most abundant, especially in keystone (â€˜â€˜cornucopianâ€™â€™) plant species visited by many insect species, such as the...

Provedor de dados: 94
Autores: MIELE,ALBERTO; RIZZON,LUIZ ANTENOR.
ABSTRACT  The interaction between rootstock, scion and the environment may induce different responses to the grapevine physiology and, consequently, to the grape composition. The vineyards of Serra Gaúcha, Brazil, are established in different soil types, each with different morphological and physicochemical attributes. Moreover, the grapevines are grafted onto a diversity of rootstocks. Therefore, this study aimed to determine the effect of 15 rootstocks in the composition of the Cabernet Sauvignon (CS) grape must. The following rootstocks were used: Rupestris du Lot, 101-14 Mgt., 3309 C, 420A Mgt., 5BB K, 161-49 C, SO4, Solferino, 1103 P, 99 R, 110 R, Gravesac, Fercal, Dogridge and Isabel, featuring some genetic diversity altogether.

ABSTRACT: Double pruning extended the harvest season of wine grape (Vitis vinifera L.) to dry winter, enabling production of high quality wines in the southeastern Brazil. Winter harvest allows grapes to fulfill not only technological maturation, but also phenolic ripeness. Winter wines from Syrah grapes harvested from eight vineyards in southeastern Brazil during three harvests were analyzed for their chemical and aromatic composition after bottling and after ageing for 20, 30, and 42 months in bottle. Winter wines have high content of total phenolic compounds, which remained almost constant through ageing, as well as color intensity. Malvidin 3-O-glucoside stood out among anthocyanins, remaining 5-10 % after 39 months of ageing. Moreover, malvidin...

The construction of reservoirs imposes substantial impact on freshwater ecosystems and changes the ecological aspects of the lotic system downstream of dams. We hypothesized an increasing dissimilarity between communities in the sampling sites according to increasing distance from the Porto Primavera Dam. In addition, we expect that the rotifer community in the last sampling site will be influenced more by environmental variables related to trophic status. Samplings were conducted under the water surface of ten sites on the Paraná River in August 2013. Environmental variables were also determined. The highest number of taxa belonged to families Brachionidae, Lecanidae and Trichocercidae. The most abundant species was observed to Synchaeta oblonga,...

A well-standardized sampling procedure applied on four collecting trips to the same sites on four areas resulted on 944 samples. All males collected were identified by analyses of the genitalia, this being the only data set used. One hundred and twenty five species were detected amongst the 29,289 males analyzed. From them 57,6% could be identified as described species. Thirteen of the species found were absent from the previous species list for the state of São Paulo State, thus represent an increase of 13% on the number known. We argue that the majority of the 53 unidentified species are in fact undescribed. The sites studied...

Provedor de dados: 57
Autores: ZALOCAR DE DOMITROVIC,YOLANDA; ASSELBORN,VIVIANA M.; CASCO,SYLVINA L.
Species composition, biomass and diversity of the phytoplankton in a subtropical lake (27°29'S; 58°45'W) were studied from February 1995 to March 1996. One or two samples were taken monthly in the limnetic and the littoral area. Cell counts were done by the Utermöhl method (1958). Phytoplankton biomass varied among 2.38 and 45.59 mm³.m-2 with a mean value of 12.11 (±10.52) mm³.m-2. The population density oscillated among 0.3x10(6) and 4.7x10(6) ind.cm-2. Cyanophyta was the dominant group all the year contributing among 25% and 83% of the total biomass. Cylindrospermopsis raciborskii, Aphanizomenon sp. and Microcystis aeruginosa were the dominant species. The Chlorophyta, second group in importance, contributed among 8% and 50% being Botryococcus braunii...

Variation of density, species composition and dominance of Rotifers at a shallow tropical reservoir (Broa reservoir, SP, Brazil) in a short scale time
Provedor de dados: 57
Autores: RODRÍGUEZ,M. P.; MATSUMURA-TUNDISI,T.
Rotifers are the predominant group of zooplankton found in the majority of reservoirs, constituting more than 60% of the total zooplankton present. Being opportunistic organisms, they easily adapt to changes in environmental conditions, and it is therefore difficult to establish a constant level of composition and occurrence of a species in specific areas at specific times. In order to establish how changes in composition and predominance of a species occurs within a dynamic system, the daily variation in the total density of rotifers and that of the dominant species were studied at short intervals during a period of 20 days at Lobo (Broa) reservoir. Filinia pejleri and Keratella americana were the predominant species, making up 64.3% of the total...

Autores: Gewehr,Márcia Flach; Pagno,Carlos Henrique; Danelli,Daiane; Melo,Lívia Marchi de; Flôres,Simone Hickmann; Jong,Erna Vogt de.
ABSTRACT The aim of this study was to evaluate quinoa flakes and bread prepared with the pseudocereal with regard to nutritional aspects by determining chemical composition, content of tocopherols and fatty acid composition as well as to possible beneficial effects in Wistar rats given commercial feed supplemented or not with quinoa flakes and cholesterol. The following parameters were determined: weight gain, food intake, liver weight, fat in liver and lipid profile in blood and liver. The results showed that processing affected the nutritional characteristics of bread because there was a significant increase in dietary fiber content but reduction in soluble fiber. Increased fiber did not influence food intake or weight gain. Regarding fat in liver of...

Cooking ways on composition of intramuscular phospholipid fatty acids of inra rabbit
Provedor de dados: 65
Autores: Shan,Xue.
ABSTRACT:  The effect of boiling, microwaving and aluminium (Al) foil-baking on composition of intramuscular phospholipid fatty acids of Inra rabbit was evaluated. Results showed that, the proportion of polyunsaturated fatty acids (PUFA)(e.g. C18:2n-6, C20:4n-6, C20:5n-3, C22:5n-3 and C22:6n-3) and monounsaturated fatty acids (MUFA)(e.g. C18:1n-7 and C18:1n-9) of treated longissimus dorsi muscle (LD) decreased, whilst the proportion of saturated (SFA)(e.g. C16:0 and C18:0) and n-6/n-3 value increased during cooking. Among the three treatments, microwaving can do better to stop the unsaturated fatty acids (UFA) being destroyed than boiling and Al foil-baking. However, boiling treatment did more serious damage to PUFA portion. Even so, the n-6/n-3 values of...

Autores: Souza,Hugo Antonio Lima de; Bentes,Ádria de Sousa; Ladeira,Taiana Marina Souza; Lopes,Alessandra Santos; Pena,Rosinelson da Silva.
This study evaluates the physical and physicochemical properties of three sugary cassava (Manihot esculenta Crantz) landraces: São Francisco Bag 3, Manicueira 62, and Castanhal Iracema. These three landraces showed high estimated productivity (≥3.93kg plant-1) and had a high sugar content (≥3.92g 100g-1 of root), making them viable for use in syrup production, especially the São Francisco Bag 3 landrace (4.76g 100g-1). The Manicueira 62 landrace had the highest starch content (4.40g 100g-1). The three sugary cassava landraces exhibited high levels of cyanide (&gt;195mg kg-1), indicating the need for processing prior to consumption.
