25. Visualização de dados genômicos do fungo Paracoccidioides brasiliensis
Genome sequencing projects developed worldwide produce an enormous and growing volume of information. These informations are usually described in text, HTML (Hypertext Markup Language) or XML (Extensible Markup Language) format, and they can be stored on hundreds or even thousands of pages. The storage and analysis of these information require computational

26. Efeito da temperatura durante a diferenciação de gemas, floração, crescimento e desenvolvimento de frutos em pessegueiro na região de Pelotas, RS. / Effect of the temperature during bud differentiation, blooming, fruit growth and development in peach tree in the area of Pelotas,RS
As horas de frio necessárias às gemas vegetativas e floríferas, quando insuficientes, limitam a produção de pessegueiros nas zonas subtropicais e temperadas brasileiras. A redução na produtividade pode ocorrer também, devido a variações bruscas na temperatura durante os períodos de diferenciação das gemas, préfloração, floração, crescimento

27. Population ecology and biology of CTENUS FASCIATUS and ENOPLOCTENUS CYCLOTHORAX in the Upper Ribeira karst are, southeastern Brazil (Araneae: Ctenidae) / BIOLOGIA E ECOLOGIA POPULACIONAL DE CTENUS FASCIATUS MELLO-LEITÃO E ENOPLOCTENUS CYCLOTHORAX (BERTKAU) EM CAVERNAS DO ALTO RIBEIRA, IPORANGA, SP (ARANEAE: CTENIDAE)
Ctenus fasciatus e Enoploctenus cyclothorax (Araneae: Ctenidae) from caves in the Alto Ribeira karst area, Iporanga Co., southern State of São Paulo, were studied with focus on their distribution in the subterranean habitat, population ecology, movements, feeding, and reproduction and growth. The populations of C. fasciatus from Lage Branca Cave, in the Par

28. Pollinators in strawberry crop(Fragaria x ananassa Duchesne - Rosaceae) / Estudo de agentes polinizadores em cultura de morango (Fragaria x ananassa Duchesne - Rosaceae)
The aims of this study were: to investigate potencial pollinators of strawberry crops in commercial fields; to verify the contribution of several pollination agents on strawberry productivity, studying the floral and reproductive biology of some commercial cultivars; to evaluate the possibility of the rational use of stingless bees in strawberry pollination

29. Experimental evidence for a demographic cline in Panstrongylus megistus populations
The population biology of three populations of Panstrongylus megistus was compared to determine possible influence on the behaviour and epidemiological importance of this species. The results demonstrated differences in terms of egg eclosion time, nymphal mortality and development rates, and feeding and defaecation rates. These differences appeared to follow

30. Cytogenetics and immature embryo culture at Embrapa Trigo breeding program: transfer of disease resistance from related species by artificial resynthesis of hexaploid wheat (Triticum aestivum L. em. Thell)
Worldwide wheat (Triticum aestivum L. em. Thell, 2n = 6X = 42, AABBDD) breeding programs aim to reorganize genotypes to achieve better yields, environmental adaptation and food quality. The necessary interdisciplinarity for breeding purposes requires an accurate choice of the most appropriate cellular and/or molecular strategies available to be integrated wi

31. Biologia de reprodução de especies de Kielmeyera (Guttiferae) de cerrados de Brasilia, DF
This study deal with reproductive biology of two sympatric wood species of the genus Kielmeyera (Guttiferae), K. coriacea and K.speciosa. Pollination, dispersal and establishment of seedlings were studied to characterize the reproductive process and its adaptation to Cerrado vegetation conditions. The study was conducted from march, 1984 to January, 1985 in

32. Biology of Borrelia hermsii in Kelly Medium
More than 800 Borellia hermsii in mouse plasma were required for establishment of growth in an artificial medium (Kelly), but only a single organism of a fully adapted strain (25th subculture) was required for a successful subculture. As judged by generation time, maximal concentration in culture, and length and motility of the organism, the process of adapt

33. Pollinator preference and the evolution of floral traits in monkeyflowers (Mimulus)
A paradigm of evolutionary biology is that adaptation and reproductive isolation are caused by a nearly infinite number of mutations of individually small effect. Here, we test this hypothesis by investigating the genetic basis of pollinator discrimination in two closely related species of monkeyflowers that differ in their major pollinators. This system pro

34. Darwinian medicine: Applications of evolutionary biology for veterinarians
Every medical phenomenon has both a mechanistic explanation and an evolutionary explanation. Veterinarians are accustomed to dealing with the mechanistic, the “what” or the “how”, of various disease conditions, and applying treatment accordingly. Darwinian medicine is a field that addresses the evolutionary explanation, the “why” for various medi

35. Global analysis of predicted proteomes: Functional adaptation of physical properties
The physical characteristics of proteins are fundamentally important in organismal function. We used the complete predicted proteomes of >100 organisms spanning the three domains of life to investigate the comparative biology and evolution of proteomes. Theoretical 2D gels were constructed with axes of protein mass and charge (pI) and converted to density es

36. Biology of Moderately Halophilic Aerobic Bacteria
The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while syn
