1. The aquatic species Pontederia azurea and P. crassipes (Pontederiaceae) in the Pantanal, Brazil: evidence of how plant structure can simultaneously reflect phylogeny and ecology
ABSTRACT Hydric fluctuations in the Pantanal comprise annual dry and wet seasons that modify local diversity and plant morphology and anatomy. Widespread in this wetland are the sympatric Pontederia azurea and P. crassipes, which, although primarily aquatic, can also develop in non-flooded environments. This study undertook a comparative investigation of the

2. Patterns recognition methods to study genotypic similarity in flood-irrigated rice
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t

3. LA PARATRADUCTION DE L’IDENTITÉ DANS LES ESPACES DE TRADUCTION ET D’INTERPRÉTATION EN MILIEU SOCIAL (TIMS)
ABSTRACT When we address the issue of identity in TIMS spaces, we face an essential question. Indeed, the relationship with the other is evident in Health practices. What about these relationships, when the cultural diversity of our current societies redraws the patterns of identity established in previous models? In this paper we will deal with the question

4. Patterns of species diversity in different spatial scales and spatial heterogeneity on beta diversity
ABSTRACT Patterns of species diversity are essential to understand community structure. We aimed to determine species diversity and patterns of beta diversity in different spatial scales. We sampled three thousand individuals between the coordinates 22°10'S to 22°16'S and 47°47'W to 48°00'W to assess species diversity in three spatial scales (maximum dis

5. 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

6. Seasonal and longitudinal variation in fish assemblage structure along an unregulated stretch of the Middle Uruguay River
RESUMO Os padrões de diversidade e suas causas continuam sendo questões importantes, especialmente em ecossistemas que preservam condições naturais. Este é o caso da diversidade de peixes em grandes rios neotropicais. Neste contexto, investigamos padrões de diversidade de peixes ao longo de um extenso gradiente fluvial (ca. 450 km) no médio rio Urugua

7. Genotyping of Malassezia pachydermatis disclosed genetic variation in isolates from dogs in Colombia
RESUMO: Malassezia pachydermatis é uma levedura lipofílica e dependente de lipídios, principalmente da pele de animais. Sendo, por essa razão, considerada uma espécie zoofílica e causadora de otite externa em cães. Neste sentido, aspectos associados à sua epidemiologia e patogenicidade constituem um tema de interesse científico. O objetivo deste est

8. RELATIONSHIP BETWEEN SOIL SEED BANK AND CANOPY COVERAGE IN A MINED AREA
RESUMO Os objetivos deste estudo foram avaliar e correlacionar dados do banco de sementes do solo e do dossel (abertura de dossel-% Canopy Openness e índice de área foliar-IAF) em uma área minerada em processo de restauração por regeneração natural. A área de estudo localiza-se na Zona da Mata Mineira, que apresenta predomínio de Florestas Estaciona

9. Functional patterns of tree communities in natural Araucaria forests and old monoculture conifer plantations
ABSTRACT A functional perspective of tree communities is helpful for understanding forest dynamics, especially vegetation recovery after other land uses. Knowledge about ecological filters and survival strategies of trees are also important for the restoration of degraded areas. This study aimed to evaluate the functional composition and structure of adult a

10. Temporal distribution of fruit-feeding butterflies (Lepidoptera, Nymphalidae) in the eastern extreme of the Amazon region
RESUMO A pluviosidade é considerada um dos fatores mais determinantes na sazonalidade de insetos na região amazônica. No entanto, poucos estudos analisaram a dinâmica temporal de borboletas frugívoras na Amazônia brasileira, especialmente em sua porção oriental. Aqui, avaliamos os padrões de diversidade e a distribuição temporal de borboletas frug
