1. Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae)
Sand fly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon. Therefore, a fragment of the cytochrome c oxidase subunit I (COI) gene is used for taxon barcoding to resolve this kind of problem. This study incorpor

2. A organização de uma revisão de literatura por meio da Tree of Science (Árvore da Ciência): um exemplo sobre a avaliação da pós-graduação
O advento da busca por artigos por meio da Web tornou a pesquisa bibliográfica mais rápida e econômica. Difícil, no entanto, é organizar a enorme quantidade de papers que retornam da pesquisa. Embora haja na literatura inúmeros artigos sobre os métodos e técnicas de pesquisa, poucos são os trabalhos que abordam as técnicas de revisão de literatura

3. Genetic diversity of populations of the dioecious Myrsine coriacea (Primulaceae) in the Atlantic Forest
ABSTRACT Although a species’ sexual system may influence the genetic diversity of its populations in their natural environment, there have been few such studies involving indigenous species of the Atlantic Forest. Here we study Myrsine coriacea, a dioecious tree widely used in reforestation programs despite a lack of information about its natural interpopu

4. Complete sequence and comparative analysis of the chloroplast genome of Plinia trunciflora
Abstract Plinia trunciflora is a Brazilian native fruit tree from the Myrtaceae family, also known as jaboticaba. This species has great potential by its fruit production. Due to the high content of essential oils in their leaves and of anthocyanins in the fruits, there is also an increasing interest by the pharmaceutical industry. Nevertheless, there are fe

5. Phylogenetic study of Class Armophorea (Alveolata, Ciliophora) based on 18S-rDNA data
The 18S rDNA phylogeny of Class Armophorea, a group of anaerobic ciliates, is proposed based on an analysis of 44 sequences (out of 195) retrieved from the NCBI/GenBank database. Emphasis was placed on the use of two nucleotide alignment criteria that involved variation in the gap-opening and gap-extension parameters and the use of rRNA secondary structure t

6. Evaluation of techniques of forest restoration of area dominated for Leucaena leucocephala (Lam) of Wit., Ipatinga, MG / Avaliaçao de técnicas de restauração florestal de área dominada por Leucaena leucocephala (Lam) de Wit. em Ipatinga, MG
The objective this to characterize the soil seed bank an area of Ribeirão Ipanema, Ipatinga city, MG, domined for Leucaena leucocephala (PL); to compare the results gotten in the seed bank of Parque Estadual do Rio Doce’s (PERD) area delimited, same city; to analyze the sowing of one mix of seeds in modules and to evaluate the alternative of seedlings

7. A Segurança do conhecimento nas práticas da gestão da segurança da informação e da gestão do conhecimento
With the advent of an economic model called Knowledge Society, the knowledge has been identified and treated as a good, in other words, an organizational asset. It was verified the relevance of knowledge as an organizational asset, thus it evidenced the necessity to protect these assets. However, a gap to be searched was identified in the knowledge security

8. Molecular cloning and sequence analysis of growth hormone cDNA of Neotropical freshwater fish Pacu (Piaractus mesopotamicus)
RT-PCR was used for amplifying Piaractus mesopotamicus growth hormone (GH) cDNA obtained from mRNA extracted from pituitary cells. The amplified fragment was cloned and the complete cDNA sequence was determined. The cloned cDNA encompassed a sequence of 543 nucleotides that encoded a polypeptide of 178 amino acids corresponding to mature P. mesopotamicus GH.

9. Trees and treelets species in gaps and light micro-sites in 5,12ha of Restinga Forest in Ilha do Cardoso, Sao Paulo State / Espécies Arbustivo-arbóreas em clareiras e micro-sítios de luz em 5,12ha de Floresta de Restinga na Ilha do Cardoso, São Paulo
Tropical Forest dynamics studies elucidate the importance of knowledge about the relationship between light and distribuition of species to understanding the regeneration and diversity mainteinence of these communities. To contribute with this knowledge to Restinga Forest species this study described the distribuition of trees with dbh (diameter at breast hi

11. Regeneração natural de florestas secas : implicações para a restauração / Natural regeneration of tropical dry forests : restoration implications
A ecologia da restauração é prioridade de pesquisa para florestas secas, pois praticamente toda a sua cobertura foi convertida em áreas agrícolas. Porém, até este momento a literatura sobre a regeneração natural e restauração de florestas secas é escassa, comparada às florestas úmidas. A literatura existente mostra que os mecanismos de regenera

12. Contribuições ao Estudo Comparativo do Fibrinóide em Placentas Humanas, de Gestações Normais e com Pré-eclâmpsia
Human placenta is a temporary organ, but indispensable to the fetal and embryonic development of each individual; its main function consists in the fetal-maternal exchanges. Its principal components are the basal and chorionical plates, with the villous tree and the maternal-bood gap interposed between them. In the villous tree, we find the fibrin, acellular
