Os índios kambiwá de Pernambuco: arte e identidade étnica

This research intends to analyse the process of symbolic reelaboration of a Brazilian Northeastern indian group – the Kambiwá of Pernambuco – through the study of its art production for commerce, of ritual objects and the indumentary utilization of certain " visual signals " normally recognized by the group and/or "public opinion" as indian ethnic attributes.Este estudo pretende analisar o processo de reelaboração simbólica de um grupo indígena nordestino – os Kambiwá, de Pernambuco – através do exame de sua produção artesanal para a venda, dos objetos rituais e da utilização de determinados “signos visuais” indumentários, normalmente reconhecidos pelo grupo e/ou pela “opinião pública” como atributos étnicos indígenas

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

Uma etnologia dos "índios misturados"? Situação colonial, territorialização e fluxos culturais

Até recentemente os estudos sobre os povos e culturas indígenas do Nordeste brasileiro não constituíram um objeto mais sistemático de investigações, parecendo apenas propiciar uma etnologia secundária e menor. Na visão do autor, isso decorreu da dificuldade de aplicação àquelas culturas dos pressupostos da antropologia americanista, a qual opera com modelos societários que enfatizam a descontinuidade cultural, bem como a objetividade e a exterioridade do observado em face do pesquisador e de sua sociedade. Dialogando com diferentes perspectivas teóricas, o autor delineia ou reelabora algumas noções como, respectivamente, as de "territorialização", "situação colonial", "diáspora" e "viagem da volta" que lhe permitem realizar uma análise compreensiva do processo histórico que veio a transformar tais populações nos grupos étnicos atuais. Sugere, ao final, que os estudos que vêm sendo realizados no Brasil e em diferentes partes do mundo sobre "índios misturados" (isto é, relações interétnicas em áreas de colonização muito antiga) podem contribuir para a construção de uma antropologia mais articulada com a história.<br>Until quite recently, indigenous peoples in the Brazilian Northeast were not the object of systematic investigation, rather appearing to inspire a kind of secondary, lesser ethnology. According to the author, this oversight resulted from a difficulty in applying the premises of Americanist anthropology to such cultures, since the latter operates with societal models emphasizing both cultural discontinuity and the objectivity and externality of the observed vis-à-vis the researcher and his/her society. By establishing a dialogue with different theoretical perspectives, the author delineates or reworks several notions, such as "territorialization", "colonial situation", "diaspora", and "return journey", allowing him to produce a comprehensive analysis of the historical process which turned such populations into the current ethnic groups. Finally, he suggests that studies on "mixed Indians" (i.e., relations between ethnic groups in areas of very old colonization) in Brazil and elsewhere can help construct an anthropology that is better articulated with history
