1. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

2. Development of the mosaic of dominant arboreal ants and its importance to the biological control of insects associated with cocoa (Theobroma cacao L.) / Desenvolvimento do mosaico de formigas arborícolas dominantes e sua importância no controle biológico natural dos insetos associados ao cacaueiro (Theobroma cacao L.)
Agroforests contribute to the survival of many native species. The cocoa plantations inserted in the Atlantic Forest biome in Southeast Bahia contribute to the conservation of a large amount of organisms, including ants. The evaluation of the ontogenetic succession of ants can help understanding the mosaic dynamics of the arboreal ants. Since this mosaic can

3. IMPLICAÇÕES DO MUTUALISMO TROFOBIÓTICO COM HEMÍPTEROS NA ATIVIDADE DE FORRAGEIO DE FORMIGAS ARBORÍCOLAS EM UM ECOSSISTEMA ARBÓREO MONTANO / IMPLICAÇÕES DO MUTUALISMO TROFOBIÓTICO COM HEMÍPTEROS NA ATIVIDADE DE FORRAGEIO DE FORMIGAS ARBORÍCOLAS EM UM ECOSSISTEMA ARBÓREO MONTANO
This study investigates a new case of trophobiotic interaction that occurs between ants and the herbivore Calloconophora pugionata, specialist of Myrcia obovata. In the first chapter we describe the trophobioses and analyze the benefits of the tending ants for treehopper survival and fecundity. Using an exclusion experiment we show that the absence of tendin

4. Bidens mosaic virus: detecção via RT-PCR e identificação de Galinsoga parviflora como um novo hospedeiro natural do vírus
O Bidens mosaic virus (BiMV) é uma espécie tentativa do gênero Potyvirus, que infecta alface (Lactuca sativa). Na ausência de métodos eficientes para diagnose deste vírus, o objetivo do trabalho foi a síntese de oligonucleotídeos específicos e sua otimização em testes de RT-PCR em uma só etapa, partindo-se de extrações de RNA total. Os oligonuc

5. ASSEMBLÉIAS DE FORMIGAS DO PARQUE ESTADUAL DO ITACOLOMI (MG) E RELAÇÕES INTRA E INTERESPECÍFICAS ENTRE ESPÉCIES DOMINANTES
Arboreal ants usually show a strong territolialist behavior, defending aggressively their foraging sites or the area surrounding their nest against individuals of other colonies. Thereby, the most aggressive ants with larger distribution, which may be considered dominants, defines the ant assemblage structure by shaping species distributions into threedimens

6. The sequence of RNA segment 1 of influenza virus A/NT/60/68 and its comparison with the corresponding segment of strains A/PR/8/34 and A/WSN/33.
The complete nucleotide sequence of RNA segment 1 of influenza virus A/NT/60/68, corresponding to the PB2 protein, has been determined. It is 2341 nucleotides long, encoding a predicted product of 759 amino acids with a net charge of +27 1/2 at neutral pH. The predicted amino acid sequence has been compared to the equivalent sequences in influenza viruses A/

7. Viridans Group Streptococci Are Donors in Horizontal Transfer of Topoisomerase IV Genes to Streptococcus pneumoniae
A total of 46 ciprofloxacin-resistant (Cipr) Streptococcus pneumoniae strains were isolated from 1991 to 2001 at the Hospital of Bellvitge. Five of these strains showed unexpectedly high rates of nucleotide variations in the quinolone resistance-determining regions (QRDRs) of their parC, parE, and gyrA genes. The nucleotide sequence of the full-length parC,
