13. Genetic and morphological characterisation of a new species of the genus Hysterothylacium (Nematoda) from Paralichthys isosceles Jordan, 1890 (Pisces: Teleostei) of the Neotropical Region, state of Rio de Janeiro, Brazil
Taking into account the difficulties of taxonomic identification of larval anisakid nematodes based on morphological characters, genetic analyses were performed, together with those usually applied, in order to identify anisakid larvae found in the flounder Paralichthys isosceles from the littoral of the state of Rio de Janeiro, Brazil. The analysis of 1,820

14. Variação geográfica de Hylaeamys yunganus (Thomas, 1902) na América do Sul (Rodentia: Sigmodontinae) / Geographic variation and phylogeography of Hylaeamys yunganus (Thomas, 1902) (Rodentia: Sigmodontinae)
Hylaeamys yunganus is a rodent of the Oryzomyini tribe presenting samples distributed through the Amazon rainforests and occupies a wide altitudinal gradient, which extends from sea level up to ca. 2,000m. Information available in the literature suggests that populations of H. yunganus from Venezuela, Colombia, Ecuador, Peru and western Brazil have large bod

15. Intragenomic variation in the second internal transcribed spacer of the ribosomal DNA of species of the genera Culex and Lutzia (Diptera: Culicidae)
Culex is the largest genus of Culicini and includes vectors of several arboviruses and filarial worms. Many species of Culex are morphologically similar, which makes their identification difficult, particularly when using female specimens. To aid evolutionary studies and species distinction, molecular techniques are often used. Sequences of the second intern

16. Marcadores fAFLP na caracterização de três genótipos de umezeiro selecionados como porta-enxertos para pessegueiro
O objetivo deste trabalho foi caracterizar a diversidade genética existente em três genótipos de umezeiro (Clone 05, cv. Rigitano e Clone 15) e identificar marcadores moleculares fAFLP (fluorescent Amplified Fragment Lenght Polymorphism) passíveis de serem utilizados na discriminação dos três genótipos de umezeiro selecionados como porta-enxertos par

18. Agricultura familiar e ruralidade em Ouro Fino-MG / Family farming and rurality in Ouro Fino-MG
The debate about "new" ruralities calls attention to the other functions, meanings and destinations of rural spaces now seen not only as the place for agricultural production, but carrying traditions and a natural richness that must be preserved. In that sense family farming is evoked as potentially more diversified, less dangerous to the natural balance and

19. Variations in the gonostyle of Nyssomyia intermedia (Lutz & Neiva) (Diptera: Psychodidae)
This paper describes sand flies similar to Nyssomyia intermedia (Lutz & Neiva) with variations in the number of spines at the gonostyle and tests the hypothesis whether these specimens belong or not to N. intermedia species. Using Principal Component Analysis and Neighbour Joining, the measurements of 15 structures of the phlebotomine with variations in numb

20. Phylogenetic analysis of Biomphalaria tenagophila (Orbigny, 1835) (Mollusca: Gastropoda)
Mitochondrial DNA of Biomphalaria tenagophila, a mollusc intermediate host of Schistosoma mansoni in Brazil, was sequenced and characterised. The genome size found for B. tenagophila was 13,722 bp and contained 13 messenger RNAs, 22 transfer RNAs (tRNA) and two ribosomal RNAs (rRNA). In addition to sequencing, the mitochondrial DNA (mtDNA) genome organizatio

21. Variación florística de especies arbóreas a escala local en un bosque de tierra firme en la Amazonia colombiana
This study was carried out in a 5-ha permanent plot established in the Amacayacu National Park, Colombian Amazonia. We assessed the extent at which floristic patterns of tree species were determined by either the environmental variation or the spatial configuration in tierra firme forests. Floristic and environmental variation was assessed on quadrants of 20

22. Educação cristã na igreja em células: análise crítica da concepção de ensino no modelo de treinamento do Ministério Igreja em células no Brasil
O presente trabalho tem como objetivo a análise da concepção de ensino da Igreja em Células, à luz do modelo de Ralph W. Neighbour Jr., adotado pelo Ministério de Igrejas em Células no Brasil, sob a perspectiva da formação cristã continuada na fé da Igreja Reformada. A visão da Igreja em Células é de que a estrutura e os valores da igreja tradi

23. Phylogenetic relationships and the evolution of mimicry in the Chauliognathus yellow-black species complex (Coleoptera : Cantharidae) inferred from mitochondrial COI sequences
The phylogenetic relationships of twelve species of Chauliognathus were investigated by studying the mitochondrial cytochrome oxidase I gene. A 678 bp fragment of the COI gene was sequenced to test the hypothesis that the Müllerian mimicry species of the “yellow-black” complex make up a monophyletic clade, separated from species with other colour patter

24. Análise das relações entre espécies do grupo Quadrifidum, subgênero Simulium (Psaroniocompsa) (Diptera, Simuliidae) utilizando o gene Citocromo Oxidase I
Taxonomic knowledge of Simuliidae (Diptera) in the Neotropical region has advanced. In Brazil, where three genera have been recorded, most of the species are in the genus Simulium and are distributed among eight subgenera. In spite of the above-mentioned taxonomic advance, molecular tools have rarely been used in studying these organisms. The sequencing of g
