1. Response to commentary by Howard Waitzkin
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

4. Influence of growth regulators on distribution of trichomes and the production of volatiles in micropropagated plants of Plectranthus ornatus
ABSTRACT The profile of volatile organic compounds, the glandular and non-glandular trichomes of Plectranthus ornatus, obtained by in vitro cultivation, was evaluated in plants grown in Murashide and Skoog medium supplemented with benylaminopurine at 4.5, 9.0, and 18.0 µM + naphthaleneacetic acid at 5.37 µM, kinetin at 4.7, 9.3 and 18.5 µM + naphthaleneac

5. Pollen morphology and its taxonomic significance in the genus Bomarea Mirb. (Alstroemeriaceae) - II. Subgenus Bomarea
Pollen morphology of 52 species (out of c. 79) of the Bomarea subgenus Bomarea was examined using light microscopy and scanning electron microscopy (SEM), or using SEM alone. The studied species of Bomarea were stenopalynous, characterized by large, oblate, monosulcate monads with reticulate exine sculpture in most species. Wide variation was observed in qua

6. Composición de lianas y bejucos en el Chocó Biogeográfico Colombiano
AbstractIn order to determine the distribution patterns of lianas and vines in the Colombian Chocó biogeographic, we constructed a data base of presence of species of lianas and vines reported to December 2012, from digital databases, records scientific literature and direct inspection of herbarium specimens considering ecosystem types (environments), from

7. Genetic structure and diversity of a soybean germplasm considering biological nitrogen fixation and protein content
Biological nitrogen fixation (BNF) has global economic and environmental importance, but has often not been considered in soybean [Glycine max (L.) Merrill] breeding programs. Knowing the genetic diversity and structure of a population within a germoplasm represent a key step for breeding programs. This study aimed at determining the structure of the populat

8. Genetic structure of Argentinean hexaploid wheat germplasm
The identification of genetically homogeneous groups of individuals is an ancient issue in population genetics and in the case of crops like wheat, it can be valuable information for breeding programs, genetic mapping and germplasm resources. In this work we determined the genetic structure of a set of 102 Argentinean bread wheat (Triticum aestivum L.) elite

9. Estudo e desenvolvimento de algoritmos para agrupamento fuzzy de dados em cenários centralizados e distribuídos / Study and development of fuzzy clustering algorithms in centralized and distributed scenarios
Agrupamento de dados é um dos problemas centrais na áea de mineração de dados, o qual consiste basicamente em particionar os dados em grupos de objetos mais similares (ou relacionados) entre si do que aos objetos dos demais grupos. Entretanto, as abordagens tradicionais pressupõem que cada objeto pertence exclusivamente a um único grupo. Essa hipótese

10. Agrupamento de dados fuzzy colaborativo / Collaborative fuzzy clustering
Nas últimas décadas, as técnicas de mineração de dados têm desempenhado um importante papel em diversas áreas do conhecimento humano. Mais recentemente, essas ferramentas têm encontrado espaço em um novo e complexo domínio, nbo qual os dados a serem minerados estão fisicamente distribuídos. Nesse domínio, alguns algorithmos específicos para agr

11. Técnicas de combinação para agrupamento centralizado e distribuído de dados / Ensemble techniques for centralized and distributed clustering
A grande quantidade de dados gerada em diversas áreas do conhecimento cria a necessidade do desenvolvimento de técnicas de mineração de dados cada vez mais eficientes e eficazes. Técnicas de agrupamento têm sido utilizadas com sucesso em várias áreas, especialmente naquelas em que não há conhecimento prévio sobre a organização dos dados. Contudo

12. Relações morfométricas e genética populacional de Culex quinquefasciatus (Diptera: Culicidae) / Morphometric relationships and population genetics of Culex quinquefasciatus
Objective. The Culex (Culex) quinquefasciatus Say 1823 is widely distributed in human settlements, and is a vector in the transmission cycles of pathogens such as arboviruses and filarids. This species belongs to Cx pipiens complex, whose main characteristic is the morphologic similarity of their species. This study aimed to characterize genetic and morpholo
