13. The role of terrestrial bromeliads in determining the spatial organization of plant life forms in a tropical coastal forest
ABSTRACT The interplay between plant-plant interactions and light heterogeneity in the understory of tropical forests has rarely been examined. We aimed to identify the relative importance of the understory light environment and terrestrial bromeliads in explaining the abundance and spatial organization of different plant life forms along a coastal forest gr

14. Evaluation of the antimicrobial activity of chitosan and its quaternized derivative on E. coli and S. aureus growth
Abstract Chitosan is largely known for its activity against a wide range of microorganisms, in which the most acceptable antimicrobial mechanism is found to include the presence of charged groups in the polymer backbone and their ionic interactions with bacteria wall constituents. This interaction suggests the occurrence of a hydrolysis of the peptidoglycans

15. INTERAÇÕES FÁRMACO-RECEPTOR: APLICAÇÕES DE TÉCNICAS COMPUTACIONAIS EM AULA PRÁTICA SOBRE A EVOLUÇÃO DOS INIBIDORES DA ENZIMA CONVERSORA DE ANGIOTENSINA
Teaching classes and events regarding the molecular aspects of drug-receptor interactions is not an easy task. The ligand stereochemistry and the spatial arrangement of the macromolecular targets highly increase the complexity of the process. In this context, the use of alternative and more playful approaches could allow students to gain a more thorough unde

16. Effects of spatial and environmental factors on benthic a macroinvertebrate community
Interactions between terrestrial and aquatic systems influence the structure of river habitats and, consequently, affect their benthic macroinvertebrate composition. The aim of this study was to evaluate the effects of spatial and environmental variables (local physical and chemical variables of water and regional landscape characteristics) on the benthic ma

17. Interações tróficas de peixes marinhos no Estado de São Paulo: banco de dados e comparações espaço-temporais / Trophic interactions of marine fish in the State of São Paulo: database and spatial-temporal comparisons
The marine ecosystems of São Paulo State are under intense anthropic pressure. Considering that trophic studies of fishes are essential to the management of ecosystems and fisheries, a fish stomach content database was built in order to summarize the available data in the region. Primary (unpublished) and secondary (published) data were inserted, representi

18. Statistical Analysis of Spatial and Temporal Variability of Maximum Precipitation Events on the Rio Grande do Sul
Abstract: A statistical analysis of precipitation at Rio Grande do Sul State was presented in this article. The aim of this work was to identify spatial and temporal patterns of maximum precipitation, which was achieved by fitting a theoretical variogram in maximum annual rainfalls and its times of occurrence. In the literature, it was found that this patter

19. Padrões de variação da diversidade funcional e de espécies em comunidades arbóreas na Floresta Atlântica do sul do Brasil
In the last years, knowledge about the functionality of tropical forest has grown. Ways of quantifying beta-diversity causes are still under developing and questions about what factors determine diversity variation, especially on a regional scale, have not been answered yet. Our aim was to identify the drivers that are defining variation of functional and sp

20. Ecologia e Conservação de Tartarugas Marinhas Através da Análise de Encalhes no Litoral Paraibano
Five sea turtle species use the Brazilian coast for reproduction and feeding: loggerhead turtle (Caretta caretta), green turtle (Chelonia mydas), leatherback turtle (Dermochelys coriacea), olive turtle (Lepidochelys olivacea) and hawksbill turtle (Eretmochelys imbricata). These species are included in the threatened categories, as much globally, according to

21. Ecologia trófica e ecomorfologia da ictiofauna de igarapés maranhenses
The trophic ecology is one of the most important aspects to understand the role of a species in the community and in the ecosystem functioning. Studies regarding the feeding of fishes coupled to the ecomorphology of a species become important tools in understanding their ecological role and position in the environment. The present study aimed to analyze the

22. AREIA BRANCA: espacialidades e interações na rede urbana de Sergipe. / AREIA BRANCA: spatial interactions and the urban network of Sergipe.
A dinâmica do espaço urbano se concretiza a partir da interdependência intraurbana e intercidades que se articulam através das ações e interações de diversos agentes modeladores do espaço. Dentro dessa lógica dialética, concomitantemente articulada e fragmentada, todas as urbes estão inseridas na rede urbana exercendo funções distintas, impresc

23. Preparo, caracterização e aplicação de fases estacionárias de poli(dimetilsiloxano-co-metilfenilsiloxano) sorvidas e imobilizadas sobre sílica e sílica zirconizada / Preparation, characterization and application of stationary phases based on poly(dimethylsiloxane-co-methylphenylsiloxane), sorbed and immobilized onto silica and zirconized silica
This work describes the development of new stationary phases (SP) based on poly(dimethylsiloxane-co-methylphenylsiloxane) sorbed and immobilized onto silica and zirconized silica for reversed phase high performance liquid chromatography. The polymer was immobilized by thermal treatment at 140 °C during 6 h, which were the conditions that produced SP with th

24. Spatial variability of forage yield and soil physical attributes of a Brachiaria decumbens pasture in the Brazilian Cerrado
The objective of this study was to analyze variability, linear and spatial correlations of forage dry mass yield (FDM) and dry matter percentage (DM%) of Brachiaria decumbens with the bulk density (BD), gravimetric (GM) and volumetric (VM) moisture, mechanical resistance to penetration (RP) and organic matter content (OM), at depths 1 (0-0.10 m) and 2 (0.10-
