1. Epidemiological and geographical distribution profile of urban sporotrichosis in the city of São Paulo
Abstract Background Sporotrichosis is the most frequent subcutaneous mycosis in Latin America, where it is considered endemic. At the end of the 20th century, the first cases of zoonotic transmission were described in Rio de Janeiro, triggering an epidemic outbreak that spread to other regions of Brazil. The lack of disease notification omits its real occur

2. Bioactive compounds and antioxidant activity of fruit of temperate climate produced in subtropical regions
Abstract Temperate fruit species, originate from regions with cold winters and well-defined climatic seasons. These fruits are also produced in subtropical and tropical regions. The aim of this study was to determine the bioactive compounds and antioxidant activity of different fruit cultivars from fruit trees of temperate climate, such as peach, pear, quinc

3. ASSESSMENT OF SOIL LOSS SUSCEPTIBILITY IN SANTA RITA WATERSHED IN SOUTHERN BRAZIL
ABSTRACT Estimation of soil loss susceptibility is of great importance for the management of watersheds. Thus, several models for soil loss prediction have been proposed. This study estimated the total annual soil loss for the Santa Rita watershed, located in southern Brazil, using the Revised Universal Soil Loss Equation. In addition, a classification to so

4. Niche differentiation between a native and an invasive species of submersed macrophyte in a subtropical reservoir
ABSTRACT Submersed macrophytes have important ecological roles but non-native invasive species may affect biodiversity and water uses. We investigated the native macrophyte Egeria najas and the invasive Hydrilla verticillata and measured their maximum colonization depth and its relationship with Secchi disk depth, their biomass along the depth gradient and t

6. CLIMATE ZONING FOR THE CULTIVATION OF AFRICAN MAHOGANY SPECIES IN BRAZIL
ABSTRACT African mahogany is the common name given to different species of the genus Khaya. They are tree species native to the African continent, which have a wood quality that allows their noble use in making fine furniture, and in the civil and naval industries. Currently, African mahogany cultivation has received notoriety in Brazil and given its climati

8. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

9. Pollen types of Sapindaceae from Brazilian forest fragments: apertural variation
ABSTRACT Morphological variations in angiosperm pollen grains may aid in the differentiation of families, genera and species. Sapindaceae pollen morphology holds promise for the recognition of taxa of this cosmopolitan family, which is well distributed in tropical regions and possesses great morphological diversity. This study presents the pollen morphology
