1. Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae)
Sand fly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon. Therefore, a fragment of the cytochrome c oxidase subunit I (COI) gene is used for taxon barcoding to resolve this kind of problem. This study incorpor

2. Diversity of Biomphalaria spp. freshwater snails and associated mollusks in areas with schistosomiasis risk, using molecular and spatial analysis tools
Resumo: A região do Médio Rio Paranapanema, em São Paulo, Brasil abriga uma diversidade significativa das espécies de Biomphalaria. É também uma região vulnerável a impactos ambientais e de saúde, como a esquistossomose. Este estudo atualiza dados sobre a distribuição de caramujos de água doce em ecossistemas de uma porção da Bacia do Médio Ri

3. Zornia (Leguminosae) no estado do Ceará, Nordeste do Brasil
Resumo Apresentamos o levantamento florístico das espécies de Zornia no estado do Ceará, como parte do projeto “Flora do Ceará”. O estudo foi baseado na análise comparativa dos caracteres morfológicos de espécimes depositados em herbários, amostras obtidas em campo, bibliografias especializadas e imagens de materiais-tipo. Para o estado foram reg

4. Biometric Responses of Soybean to Different Potassium Fertilization Management Practices in Years with High and Low Precipitation
ABSTRACT Brazilian soybean producers commonly apply maintenance potassium (K) fertilization during cultivation to restore the K taken up by plants; however, this measure can modify the morphophysiological plant characteristics, since the functions of K are closely related with plant growth and development. This study assessed the morphological changes in soy

5. Anatase crystals of unusual habit in quartz veins from the Diamantina region (Espinhaço Range, Minas Gerais)
Abstract The Espinhaço Range, in the Diamantina region (central part of the State of Minas Gerais), is known worldwide as a famous source of associated occurrence of quartz, rutile and/or anatase crystals. The latter is also a classic accompanying mineral of diamonds in the alluvial placers. Primary anatase is related to hydrothermal quartz veins cutting ge

6. Is Structural Quality as Assessed by the "Profil Cultural" Method Related to Quantitative Indicators of Soil Physical Quality?
ABSTRACT Soil and crop management systems change the soil structure, thereby affecting soil quality. The “profil cultural” method (PCM) has been used to identify the effects of management systems on soil structure; however, few studies relate the structures identified by the PCM to quantitative indicators of soil structural quality. This study aimed to q

7. Isolation, identification, and biocontrol of antagonistic bacterium against Botrytis cinerea after tomato harvest
ABSTRACT Tomato is one of the most important vegetables in the world. Decay after harvest is a major issue in the development of tomato industry. Currently, the most effective method for controlling decay after harvest is storage of tomato at low temperature combined with usage of chemical bactericide; however, long-term usage of chemical bactericide not onl

8. Physical Properties of Soil Structures Identified by the Profil Cultural under Two Soil Management Systems
ABSTRACT Soil structure plays an important role in water retention, infiltration capacity, porosity, and penetration resistance. The aim of this study was to evaluate the unsaturated hydraulic conductivity and physical properties of Oxisol soils (bulk density and macro-, micro-, and total porosity) in the structures identified using the profil cultural metho

9. Ethnopedology of a Quilombola Community in Minas Gerais: Soils, Landscape, and Land Evaluation
ABSTRACT Quilombolas are Afro-brazilian rural peasants who descended from escaped slaves who tried to carve out territories of autonomy (called Quilombos) by collective organization and resistance. Despite many anthropological and ethnopedological studies, little research has been carried out to identify the agricultural practices and the knowledge of people

10. Dental caries at Lapa do Santo, central-eastern Brazil: An Early Holocene archaeological site
ABSTRACT The origin and dispersion of the first Americans have been extensively investigated from morphological and genetic perspectives, but few studies have focused on their health and lifestyle. The archaeological site of Lapa do Santo, central-eastern Brazil, has exceptionally preserved Early Holocene human skeletons, providing 19 individuals with 327 pe

11. Tetrapterys Cav. (Malpighiaceae) from Brazilian Midwest
We present a floristic survey of the genus Tetrapterys (Malpighiaceae) from the Brazilian Midwest, including morphological descriptions, keys, comments on taxonomy and phenology, illustrations, and distribution maps for all species. Nine species were found in the studied area: T. ambigua, T. crispa, T. discolor, T. hassleriana, T. jussieuana, T. microphylla,

12. Consciência morfológica: que papel exerce no desempenho ortográfico e na compreensão de leitura?
Morphological awareness refers to the ability of reflecting on the smallest units of meaning in a language and in using them intentionally in word structuring and recognition. In this study arguments are presented to support the idea that in Portuguese, as in other alphabetic languages, morphological awareness contributes to both reading comprehension and fo
