A Praieira revisitada: considerações sobre o debate

The aim of our paper was to introduce the public not only to the multiple aspects of the Praieira Rebellion, but also to foster the debates concerning crucial problems that, if one has the Praieira movement as a focal point, might be further researched. That rebellion is much more than an event, it is above all a microcosmos that enables a closer look on different aspects of the Brazilian imperial history. Furthermore, the Praieira Rebellion has an advantage when compared to other movements from the same period: many scholars have already researched and written about it, and there are is a handful of sources available for further studies.O objetivo central do nosso texto foi apresentar ao público leitor não apenas as diversas faces da Insurreição Praieira, mas também compartilhar os debates em torno dos problemas que podem ser investigados a partir do estudo de um movimento que encantou toda uma geração de historiadores. A Praieira não é apenas um evento relevante. Ela também é um microcosmo através do qual podemos observar vários aspectos da história do Brasil imperial, com uma vantagem em relação a outros movimentos coevos: sobre ela existe uma rica historiografia e, sobretudo, muitas fontes disponíveis

A Insurreição Praieira

The Praieira Insurrection (1848) drew the attention of several historians, not just for its magnitude, the participation of landowners and also members of the Parliament, but also because of its broader social aspects. The Praieira is deeply rooted in the disputes of the local elites for the government of Pernambuco, starting in the Independence of Brazil. But also had deep roots in the disputes in the Parliament. By the 1840's, there were two local factions competing for power in the province. Both tried to mobilize the urban population and the rural landowners. This paper discusses the recent historiography, and focuses on the diverse motivations of the participants in the rebellion, including those of the urban poor, the skilled and semi-skilled workers of Recife.A Insurreição Praieira (1848) atraiu a atenção de vários historiadores, não apenas devido à sua magnitude, a participação de proprietários rurais e membros do parlamento, mas também devido aos seus aspectos sociais mais amplos. A Praieira está enraizada nas disputas das elites locais pelo governo de Pernambuco, que começaram na Independência do Brasil. Mas ela também teve raízes nas disputas parlamentares na Corte. Na década de 1840, havia duas facções competindo pelo poder na província. Ambas tentaram mobilizar a população urbana e os proprietários rurais. Este trabalho discute a historiografia recente e enfoca as motivações dos participantes na rebelião, tanto das elites como aquelas dos homens livres pobres, os trabalhadores especializados e semi-especializados

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
