1. Multifractal analysis of soil fauna diversity indexes
ABSTRACT The objective of this study was to determine the multifractality of diversity indexes of edaphic fauna in areas with natural vegetation and in agricultural systems. Biological sampling was carried out in seven treatments (millet, maize, soybean, eucalyptus, preserved cerrado, disturbed cerrado and pasture), containing 130 pitfall traps, distributed

2. Storage protein variability in natural populations of maté (Ilex paraguariensis) in Brazil
RESUMO: A variabilidade de proteínas de reserva das sementes foi analisada em 168 árvores de quatro populações naturais de erva-mate (Ilex paraguariensis) dos estados brasileiros Rio Grande do Sul, Santa Catarina, Paraná e Mato Grosso do Sul. Estes marcadores foram utilizados para estimar o grau de diferenciação entre e dentro da espécie porque são

3. Efeitos da estrutura de habitat e do espaço sobre a diversidade de mamíferos no norte do Pantanal : uma abordagem de resolução fina
Compreender os mecanismos que causam variações espaço-temporais na diversidade biológica é uma das principais atribuições da ecologia. A teoria clássica de nicho prediz que o gradiente ambiental e sua complexidade mediam processos cruciais na estruturação das assembléias locais, permitindo a coexistência das espécies. A associação entre fatore

4. Estrutura da comunidade de macroinvertebrados bentônicos na bacia hidrográfica do Rio Forqueta (RS, BRASIL) em múltiplas escalas espaciais
Os macroinvertebrados bentônicos constituem uma importante comunidade em riachos, pois participam do fluxo de energia, sendo um importante recurso alimentar para níveis tróficos adjacentes e superiores. Formam uma fauna bastante diversificada e a estrutura desta comunidade pode ser influenciada por diversos fatores ambientais, os quais variam no tempo, no

5. SeleÃÃo local de caracterÃsticas em agrupamento hierÃrquico de documentos
Hierarchical clustering of documents is used to provide interface for navigating through collections of documents, assisting in the activity of information retrieval. As the vectors representing the documents have a high dimensionality, the presence of irrelevant terms can harm the clustering algorithm. The use of feature selection in text clustering is able

6. Estratégias para prospecção e predição de peptídeos bioativos
Chapters one and two deal with the isolation and identification of bioactive peptides from the skin secretion of Phyllomedusa hypochondrialis. The first chapter demonstrates the use of protemic techniques, mainly mass spectrometry, for the study of bradykinin related peptides (BRPs) present in the amphibians secretion and freshly dissected skin fragments. Ei

7. IsenÃÃo tributÃria: crise de paradigma do federalismo fiscal cooperativo / Tax Exemptions: crisis of the cooperative fiscal federalism paradigm
In the process of State formatting, it becomes valuable the question about power centralization / decentralization, characterizing the federalism by the unit-diversity. Its most current composition extols an harmonic and cooperative coexistence among the federated members in the search of the own federationâs interests. Moreover, itâs from the federalismâ

8. DistribuiÃÃo espaÃo-temporal da meiofauna e da nematofauna no ecossistema recifal de Porto de Galinhas, Ipojuca, Pernambuco, Brasil
From all the beaches on Pernambuco coast âPorto de Galinhasâ is the one which receives the largest tourist flow. The aims of this research were to evaluate the meiofauna and nematofauna spatial and temporal distributions in tidal ponds as well as in the inner part of the reef ecosystem. To evaluate the vertical distribution of meiofauna and Nematoda genera

9. HapScope: a software system for automated and visual analysis of functionally annotated haplotypes
We have developed a software analysis package, HapScope, which includes a comprehensive analysis pipeline and a sophisticated visualization tool for analyzing functionally annotated haplotypes. The HapScope analysis pipeline supports: (i) computational haplotype construction with an expectation-maximization or Bayesian statistical algorithm; (ii) SNP classif

10. Alternative Gene Form Discovery and Candidate Gene Selection from Gene Indexing Projects
Several efforts are under way to partition single-read expressed sequence tag (EST), as well as full-length transcript data, into large-scale gene indices, where transcripts are in common index classes if and only if they share a common progenitor gene. Accurate gene indexing facilitates gene expression studies, as well as inexpensive and early gene sequence

11. Geographical structuring in the mtDNA of Italians.
Geographical patterns of mtDNA variation were studied in 12 Italian samples (1072 individuals) by two different spatial autocorrelation methods. Separate analyses of the frequencies of 12 restriction morphs show North-South clines, differences between Sardinia and the mainland populations, and the effects of isolation by distance. A recently developed autoco

12. Molecular identification of potential pathogens in water and air of a hospital therapy pool
Indoor warm-water therapy pool workers in a Midwestern regional hospital were diagnosed with non-tuberculosis pulmonary hypersensitive pneumonitis and Mycobacterium avium infections. In response, we conducted a multiseason survey of microorganisms present in this therapy pool water, in biofilms associated with the pool containment walls, and in air immediate
