Opinião pública e política externa do Brasil do Império a João Goulart: um balanço historiográfico

Este artigo avalia a relação existente entre opinião pública e política externa no Brasil, desde o Império, em que se evidenciam os interesses das elites letradas enunciados no Parlamento, até a presidência de Jânio Quadros, quando se verifica o apogeu do populismo no Brasil. Procura estabelecer quais eram as correntes de opinião expressa que representavam a política externa nos diversos períodos da historiografia brasileira de relações internacionais. Pretende, também, avaliar a extensão da repercussão que teria a política internacional brasileira sobre a opinião nacional no mesmo período.<br>The purpose of this article is to evaluate the rapport between public opinion and Brazilian foreign policy. It proposes a historiographic analysis of the period going from the country's independence to the apogee of populism under João Goulart's presidency. It also aims to determine the groups which most evidently represented public opinion in the various periods of Brazilian history of international relations, as well as the importance of their expressed points of view in relation to the foreign policy decision-making process. Also pertinent is the comprehension of the impact which international relations may have had in society in the same period

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
