Avaliação de aspectos hematológicos, bioquímicos e de hemoparasitas em população de Didelphis aurita Wied-Neuwied, 1826 (Didelphimorphia: Didelphidae) da Serra dos Órgãos, RJ

A Floresta Tropical Atlântica apresenta uma enorme biodiversidade, e está atualmente sujeita a inúmeras pressões como a perda de área pela intensa ocupação humana, agricultura, pecuária, urbanização e industrialização. Esses impactos têm provocado desmatamento e fragmentação florestal, processos que interferem na manutenção das populações animais, inclusive afetando os ciclos silvestres de parasitas e microorganismos. Didelphis aurita é um marsupial da Mata Atlântica com alta capacidade adaptativa a ambientes perturbados. Esta espécie onívora é tolerante à fragmentação florestal, podendo sobreviver em ambientes silvestres, rurais, suburbanos e urbanos, tendo importância na conexão dos ciclos silvestres e urbanos de diversos agentes. Este trabalho teve por objetivo descrever aspectos hematológicos, bioquímicos e de hemoparasitas em Didelphis aurita de duas áreas da Serra dos Órgãos/ RJ, uma área fragmentada e outra de mata contínua. Entre julho de 2011 e fevereiro de 2012 foram capturados 61 animais que tiveram amostras de sangue avaliadas. Os resultados expressos como média desvio padrão foram: Volume Globular 38,66 % ( 4,97); Hemácias 5,40 ( 0,75) x106/mm3; Hemoglobina 12,78 ( 1,68) g/dL; VGM 71,69 ( 3,56) fl; CHGM 33,01 ( 0,63) %; Plaquetas 514,70 ( 323,10) x 103/mm3; Leucócitos 19.678,52 ( 10.152,26)/mm3; Basófilos 0,59 ( 0,72) %; Eosinófilos 13,79 ( 6,94)%; Bastonetes 0,77 ( 2,04) %; Segmentados 41,12 ( 13,95) %; Linfócitos 41,97 ( 12,97) %; Monócitos 1,75 ( 1,51)%. Para parâmetros bioquímicos encontramos os seguintes resultados: Proteínas totais 8,50 ( 1,68); albumina 3,03 ( 0,69); globulina 5,44 ( 1,66); uréia 83,57 ( 20,11); creatinina 0,44 ( 0,13); ALT 85,01 ( 65,65); AST 314,55 ( 130,58); FA 420,38 ( 371,89); GGT 19,40 ( 8,51). Os parâmetros hematócrito, hemoglobina, hematimetria, ALT, AST e FA foram maiores nos machos do que nas fêmeas. Adultos apresentaram valores de proteína plasmática total, leucócitos, hematócrito, hemoglobina, hematimetria, albumina, proteínas totais, creatinina e GGT maiores do que jovens, e o inverso ocorreu para plaquetas, globulina e FA. Animais do Fragmento apresentaram valores de massa corporal e albumina menores do que os do Garrafão, e o inverso ocorreu para GGT e globulina. Babesiasp. ocorreu em 26,6% da população, sendo mais freqüente em adultos. Estes resultados são os primeiros parâmetros de referência para Didelphis aurita na Serra dos Órgãos, contribuindo para o estudo desta espécie.

Creating a modern database from archive material - The Norman Holme archive: Interpretation of marine field research notebooks in the historical context of the MBA, 1958-83

This document provides details of the transfer of the Norman Holme archive data held in the National Marine Biological Library onto a modern database, specifically Marine Recorder. A key part in the creation of the database was the retrieval of a large amount of information recorded in field notebooks and on loosely-bound sheets of paper. As this work involved amending, interpreting and updating the available information, it was felt that an accurate record of this process should exist to allow scientists of the future to be able to clearly link the modern database to the archive material. This document also provides details of external information sources that were used to enhance and qualify the historical interpretation, such as estimating volumes and species abundances.

Pl2 resistance gene differentiates the pathogenicity in four "Plasmopara halstedii" (sunflower downy mildew) races 304, 704, 314 and 714

In order to clarify the role of Pl2 resistance gene in differentiation the pathogenicity in Plasmopara halstedii (sunflower downy mildew), analyses were carried out in four pathotypes: isolates of races 304 and 314 that do not overcome Pl2 gene, and isolates of races 704 and 714 that can overcome Pl2 gene. Based on the reaction for the P. halstedii isolates to sunflower hybrids varying only in Pl resistance genes, isolates of races 704 and 714 were more virulent than isolates of races 304 and 314. Index of aggressiveness was calculated for pathogen isolates and revealed the presence of significant differences between isolates of races 304 and 314 (more aggressive) and isolates of races 704 and 714 (less aggressive). There were morphological and genetic variations for the four P. halstedii isolates without a correlation with pathogenic diversity. The importance of the Pl2 resistance gene to differentiate the pathogenicity in sunflower downy mildew was discussed.

Determining factors of the innovative behavior of cooperatives: an analysis of the case of Castilla y León

Cooperatives have a long historical experience in the Spanish economy and have demonstrated their ability to compete against traditional firms in the market. To maintain this capability, while taking advantage of the competitive advantages associated with their idiosyncrasies as social economy enterprises, they should take into consideration that the economy is increasingly globalized and increasingly knowledge-based, especially with regards to technological content. As a consequence, the innovative capacity appears to be a key aspect in order to be able to challenge competitors. This article characterizes the innovative behavior of cooperatives in the region of Castile and Leon and analyses the internal and external factors affecting their innovative performance, based on data from a survey of 581 cooperatives. The results of the empirical analysis, which is performed by multivariate binary logistic regression on various types of innovation, lead us to identify the size of the organizations, the existence of planning, the R & D activities and the human capital as the main determining factors.

Analysis of the reading and comprehension control in scientific texts in high school students

Students' learning process can be negatively affected when their reading and comprehension control is not appropriated. This research focuses on the analysis of how a group of students from high school evaluate their reading comprehension in manipulated scientific texts. An analysis tool was designed to determine the students' degree of comprehension control when reading a scientific short text with an added contradiction. The results have revealed that the students from 1st and 3rd ESO do not properly self-evaluated their reading comprehension. A different behavior has been observed in 1st Bachillerato, where appropriate evaluation and regulation seem to be more frequent. Moreover, no significant differences have been found regarding the type of text, year or gender. Finally, as identified by previous research, the correlations between the students' comprehension control and their school marks have shown to have a weak relationship and inversely proportional to the students' age.
