Um estudo sobre argumentação, documentários e educação alimentar e nutricional
Documentários possuem relevante potencial como estratégia de educação. Contudo, há poucos estudos científicos que analisem sua aplicabilidade na educação alimentar e nutricional (EAN) e critérios de seleção. Por isso, objetiva-se tanto realizar uma análise argumentativa de um documentário como verificar elementos relevantes para seleção desse, assim qualificando a utilização deste tipo de ferramenta audiovisual como estratégia de EAN. Esta é uma pesquisa básica e qualitativa, na qual predomina a análise da estrutura argumentativa do documentário Em Defesa da Comida, complementada pela observação dos bastidores dessa argumentação. Encontrou-se que 60% das afirmações analisadas neste artigo apresentam elementos mais complexos além dos considerados básicos para um argumento ser considerado completo. Prepondera no documentário o discurso direto, autorizado, emotivo e persuasivo, o qual se direciona mais ao público leigo e adulto. Conclui-se que documentários selecionados para práticas em EAN devem observar a qualidade do conteúdo e os aspectos argumentativos para alcance da efetividade.Documentaries have relevant potential as an education strategy. However, there are few scientific studies that analyze its applicability in food and nutritional education (FNE) and selection criteria. Therefore, it is aimed both to perform an argumentative analysis of a documentary and to verify relevant elements for its selection, thus qualifying the use of this type of audiovisual tool as a FNE strategy. This is a basic and qualitative research, in which the analysis of the argumentative structure of the documentary In Defense of Food predominates, complemented by the observation behind the scenes of this argumentation. It was found that 60% of the statements analyzed in this article present more complex elements than those considered basic for an argument to be considered complete. The direct, authoritative, emotive and persuasive discourse prevails in the documentary, which is directed more towards the lay and adult public. It is concluded that documentaries selected for EAN practices should observe content quality and argumentative aspects to achieve effectiveness.Los documentos tienen un potencial relevante como estrategia de educación.

12,500+ and counting: biodiversity of the Brazilian Pampa
Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, is neglected in terms of conservation, and knowledge of its biodiversity is fragmented. We aim to answer the question: how many, and which, species occur in the Brazilian Pampa? In a collaborative effort, we built species lists for plants, animals, bacteria, and fungi that occur in the Brazilian Pampa. We included information on distribution patterns, main habitat types, and conservation status. Our study resulted in referenced lists totaling 12,503 species (12,854 taxa, when considering infraspecific taxonomic categories [or units]). Vascular plants amount to 3,642 species (including 165 Pteridophytes), while algae have 2,046 species (2,378 taxa) and bryophytes 316 species (318 taxa). Fungi (incl. lichenized fungi) contains 1,141 species (1,144 taxa). Animals total 5,358 species (5,372 taxa). Among the latter, vertebrates comprise 1,136 species, while invertebrates are represented by 4,222 species. Our data indicate that, according to current knowledge, the Pampa holds approximately 9% of the Brazilian biodiversity in an area of little more than 2% of Brazil’s total land. The proportion of species restricted to the Brazilian Pampa is low (with few groups as exceptions), as it is part of a larger grassland ecoregion and in a transitional climatic setting. Our study yielded considerably higher species numbers than previously known for many species groups; for some, it provides the first published compilation. Further efforts are needed to increase knowledge in the Pampa and other regions of Brazil. Considering the strategic importance of biodiversity and its conservation, appropriate government policies are needed to fund studies on biodiversity, create accessible and constantly updated biodiversity databases, and consider biodiversity in school curricula and other outreach activities
