Floristic Treatment

Abstract This research consists of the taxonomic-floristic treatment of taxa of Mimosoideae occurring in the Brazilian Chaco. The specimens analyzed were collected from 2004 to 2012 in Chaco remnants located in southwestern Mato Grosso do Sul, Brazil. Mimosoideae is represented by 39 taxa belonging to 14 genera; among the most representative, Mimosa (16 taxa) and Prosopis (4 taxa) are highlighted. Chloroleucon chacoense, Mimosa centurionis and Prosopis alba are new records for the Brazilian Flora. Prosopis nigra has its occurrence expanded. Mimosoideae is the second subfamily in species richness compared with other subfamilies of Leguminosae studied in the Brazilian Chaco. This work includes morphological descriptions, identification keys, illustrations and taxonomic comments.

The Republic

As a result of the field studies, analysis of publications and herbarium materials, it has been established that by now the alien flora of the Republic of Khakassia includes about 140 species of vascular plants. Of this number, more than 30 species are invasive plants included in the “Black Book of Flora of Siberia” (2016). In recent years, there has been both a fairly rapid replenishment of the flora with alien plants and a noticeable dispersal of a number of invasive species across the territory of Khakassia. For the purpose of monitoring alien plant species, we use the capabilities of the international scientific network iNaturalist.org.

Brazilian Flora

Background: Brazilian flora is rich in plants with medicinal properties, which though popular, has contributed to the development of a range of homeopathic products that use plants to treat and cure diseases. However, studies that use Brazilian plants in the treatment of metabolic disorders are still scarce in the literature. Objective: The aim of this study was to analyze the effect of hepatotoxicity Lafoensia pacari on the metabolism of mice with obesity induced by a high-fat diet and to verify the phytochemical difference between the Lafoensia pacari bark of the trunk, leaves, and branches. Methods: The plant material was collected from April to May in the municipality of Bonito de Minas, MG, Brazil. Qualitative tests for the presence of classes of secondary metabolites were performed for leaves, branches and bark of the trunk. Through histological analysis, we evaluated hepatocytes and cell lesions in the liver. Results: The comparative phytochemical analysis of the plant did not reveal alterations between the different plant parts. The phytochemical teste showed that is preferable to use the leaves to make the extract to be applied, aiming to reduce the plant aggression. After treatment, greater changes were observed in the animals that received the high-fat diet and the hydroethanolic extract; the levels of AST, ALT, albumin and creatinine that were increased, thus demonstrating a possible toxicity. There were no significant differences in body weight. In the histological analysis, the animals that received any treatments with the plant, displayed decreased liver weight and reduction in the inflammatory infiltrate. Conclusion: We conclude that Lafoensia pacari should be better evaluated for oral consumption and may cause liver damage.

Abstract The importance of continuously conducting botanical inventories has been questioned in recent decades, generating a lack of investment and interest in this area. However, several applied studies are only possible after obtaining the primary data from such surveys. Despite having the greatest richness of plants known in Brazil, several areas with knowledge gaps remain in Minas Gerais (MG) state. This is the case for the Serra da Mantiqueira, an important area for biodiversity conservation in the country. In this scenario, the phytophysiognomy of Seasonal Semi-deciduous Forest (SSF) deserves attention, as it is broadly distributed and has great relevance in the state, although subsampled. Therefore, this study aimed to present records of species for the flora of MG and discuss the need for floristic surveys in Brazil. These species were recorded in three of 10 studied remnants along expeditions performed between the years of 2012 and 2019 as part of a wide study performed in SSF remnants in the Serra da Mantiqueira which have a deficit of floristic data. Three species are recorded for the first time in MG, one species was rediscovered after more than two centuries from the last collection (which represents its nomenclatural type), in addition to nine other species which must be considered rare in the state. This study contributed to filling gaps in knowledge on Brazilian flora and also demonstrated the relevance of continuing new collections, mainly in specific subsampled areas in the interior of the country such as in SSF remnants.

Objectives: Evaluate the production and the research collaborative network on Leishmaniasis in South America. Methods: A bibliometric research was carried out using SCOPUS database. The analysis unit was original research articles published from 2000 to 2011, that dealt with leishmaniasis and that included at least one South American author. The following items were obtained for each article: journal name, language, year of publication, number of authors, institutions, countries, and others variables. Results: 3,174 articles were published, 2,272 of them were original articles. 1,160 different institutional signatures, 58 different countries and 398 scientific journals were identified. Brazil was the country with more articles (60.7%) and Oswaldo Cruz Foundation (FIOCRUZ) had 18% of Brazilian production, which is the South American nucleus of the major scientific network in Leishmaniasis. Conclusions: South American scientific production on Leishmaniasis published in journals indexed in SCOPUS is focused on Brazilian research activity. It is necessary to strengthen the collaboration networks. The first step is to identify the institutions with higher production, in order to perform collaborative research according to the priorities of each country.
