Mossoró não cabe num livro : Luís da Câmara Cascudo e a produção historiográfica do espaço mossoroense

A city is made not only to streets, sidewalks, buildings, bridges and viaducts. The city is also built by layers of sediment from the past that blend with layers of sediments present. The city's it's art, it's sociability is written. The aim of this study is to analyze how Mossoró historiographically the narrative is built by Luís da Câmara Cascudo. With this objective, we divide the work into three chapters. At first, we investigate the investment that the prefecture of the Mossoró city at the beginning of the forties, under the administration of Dix-sept Rosado, held for the construction of what would be the city's culture. A culture that was linked to the creation of a library, a museum, a university, the completion of several lectures on the themes of the city, and writing the history of Mossoró. The second chapter discusses the historical conditions of possibility that made Luís da Câmara Cascudo of the town historian. In the last chapter, we show how Mossoró was built by Cascudo from the specific analysis of the book Notas e Documentos para a história de Mossoró (1955). We discuss the conditions for its emergence, examining the interplay of interests that enabled its production

Taxonomia e biogeografia da espécie politípica Herpsilochmus rufimarginatus (TEMMINCK, 1822) (Aves: THAMNOPHILIDAE)

The genus Herpsilochmus is composed mainly of cryptic species, among them is Herpsilochmus rufimarginatus, which is currently represented by four subspecies: H. r. rufimarginatus, H. r. frater, H. r. scapularis and H. r. exiguus. Differences in plumage and vocalization suggest that there are more than one species involved in this complex. Thus this and other subspecific taxa need urgent revision, the disjunct distribution of this species also allows us to infer the relationship between birds that occur in this biome and / or different centers of endemism. This study aims to make a taxonomic revision of the taxa included in the complex time Herpsilochmus rufimarginatus based on morphological, morphometric, vocals and geographical distribution of this bird. Besides creating distribution models current potential and make the reconstruction of the distribution bygone using ecological niche modeling, and testing the niche conservatism and divergence between different subspecies. Consultations for examination of the skins of specimens of the museums: Museum of Zoology, University of São Paulo (MZUSP), National Museum of Rio de Janeiro (MN) and Emilio Goeldi Museum of Pará (MPEG), and the skins deposited at the collection of Ornithological Federal University of Rio Grande do Norte (COUFRN). We studied the following measures length of specimens: exposed culmen, culmen and total culmen nostril, tarsus, wing and tail flattened. The voice analysis was performed with vocalizations banks and / or digital banks people where 17 voice parameters were measured. This information and more available in the literature were used to assemble a bunch of data under the limit distribution of taxa and generate ecological niche models. This analyzes carried out in the program Maxent, having as model selection criterion the AUC, and the models were greater than 0.80 are considered good models. Environmental data for the realization of the modeling were downloaded on the website of Worldclim. The morphometric information, vocals and geographic distribution point for the separation of these taxa to be considering various uni and multivariate analyzes. The potential distribution models performed well (AUC> 0.80), and its distribution associated with environmental characteristics of the Amazon forest and Atlantic forest (forests of south and southeast, northeast and forest). The reconstruction of the distribution indicates a possible contact between the southern part of the Atlantic forest in the northern part of the Amazon. The analysis of niche overlap showed a low overlap between taxa and comparisons between the null model and the generated overlay link probably occurring niche conservatism. The data suggest that the taxa that occur in the Amazon and Atlantic forest represent three distinct species

Geologia e paleontologia de depósitos fossilíferos pleistocênicos do Rio Grande do Norte

This study deals with origin, sedimentary filling and fossil content of three tanks situated at Antônio Martins, Barcelona, Rui Barbosa, and Apodi counties, Rio Grande do Norte State. In addition, fossil materials from the Câmara Cascudo Museum - UFRN - Fundação Amigos do Lajedo Soledade - FALS, and from private ownership were investigated. The following families were identified: Megatberiidae, Gomphotheriidae, Mylodontidae, Equidae, Felidae, Canidae, Hydrochoeridae, Camelidae, Cervidae, Dasypodidae, Glyptodontidae, Macraucheniidae, Toxodontidae, and an undetermined Edentata Pilosa. The megafauna analysis indicated that herbivorc families occur mainly in tanks, whereas carnivore families occur in a vast proportion in an investigated ravine. Taphonomie analyses were limited to physical features because the vast majority of fossils were previously colleted without appropriate care for this kind of study. The main fossization processes were identified during diagenetie investigation. Permineralization is the most important process and replacement is the secondary one during fossilization. The study concluded that paleoenvironmental conditions during the late Pleistocene were more humid than the current one. Tropical savana, characterized by fields and cerrados , was the dominant vegetation

Edaphic characterization of a forest savanna ecotone in southeastern Brazil

Edaphic characterization of a forest savanna ecotone in southeastern Brazil. This study was motivated by the scarcity of studies involving descriptions of edaphic horizons in the transition from savanna to forest. It aims at comparing the chemical features and the texture of savanna and forest soils in one ecotone, and at considering possible edaphic influences on vegetation. In areas pertaining to the Botanical Garden of Bauru, State of São Paulo, two-meter deep pits were opened in different parts of a seasonal semi-deciduous forest and of a forested savanna to directly collect soil samples in different horizons. The physicochemical analysis revealed high contents of different nutrients, e.g., Ca and Mg, and low contents of Al in the superficial horizons of the seasonal forest, which were classified as eutrophic. Conversely, all the forested savanna horizons were considered as dystrophic. These edaphic features may be due to the different microenvironments of the studied phytocenoses.

Anatomical characterization and chemical profile of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted and non-impacted mangroves of the São Paulo Coast

Anatomical characterization and chemical profile of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted and non-impacted mangroves of the São Paulo Coast. Several sources of environmental impact have caused great damage to the flora in mangroves. Therefore, this study aimed to analyze the anatomy and chemical composition of Laguncularia racemosa (L.) Gaertn leaf blades, from impacted (Municipality of Santos) and non-impacted mangroves (Municipality of Peruibe) of the São Paulo Coast. For the leaf anatomy studies, light microscopy and scanning electron microscopy (SEM) were used. For chemical analysis, high performance liquid chromatography (HPLC) was conducted. The biometry revealed leaf tissues of plants from impacted mangroves with a less thick epidermis and mesophyll and higher width of the central vascular beam. A smaller number of stomata and higher amounts of daises in these leaves were also observed. Results were confirmed by the Student t-test (alpha = 5%). The chemical profiles revealed a higher ammount of secondary metabolites in leaves from the impacted environment.

Animais medicinais: conhecimento e uso entre as populações ribeirinhas do rio Negro, Amazonas, Brasil

O estudo tem por objetivo documentar o uso de animais na medicina caseira entre ribeirinhos do rio Negro, Amazonas, Brasil. Os dados foram coletados por meio de 92 entrevistas e de observações sobre o conhecimento e as práticas cotidianas de uso de animais medicinais. Cerca de 60 espécies animais são conhecidas com propósitos medicinais. O conhecimento é bem distribuído entre os sexos (homens e mulheres) e entre localidades (urbano e rural). O uso de animais medicinais está imerso em conceitos etiológicos e envolve uma complexa visão cosmológica do processo de cura. O êxodo rural e o acesso facilitado à medicina ocidental podem promover a perda dos conhecimentos tradicionais, o que pode ser mitigado através da valorização e da transmissão desses saberes às futuras gerações.

Hidrelétricas na Amazônia: renovabilidade e não renovabilidade da política energética. Se é desejável a renovabilidade das formas de conversão de energia, por que não é desejável renovar a política energética?

O ensaio tem a intenção de discutir, apresentando como pano de fundo os recentes projetos hidrelétricos propostos e em andamento na Amazônia brasileira, aspectos referentes aos processos de licenciamento ambiental, problemas conceituais que dizem respeito à caracterização da conversão hidrelétrica como energia limpa e renovável. Este trabalho parte da análise de planos governamentais e das discussões sobre projetos hidrelétricos, identificando a necessidade de implementar mudanças institucionais e de fortalecer as leis ambientais e de proteção dos direitos de populações tradicionais e indígenas. Propõe-se uma nova maneira de formular problemas energéticos e de planejar a oferta de energia, que leva em consideração aspectos sustentáveis e patrocinadores da discussão pública, além do entendimento e da incorporação das consequências sobre os grandes ciclos biogeoquímicos que dão suporte às conversões de energia.

Interações socioculturais com a fauna silvestre em uma unidade de conservação na Amazônia: relações de gênero e geração

Este artigo descreve as interações socioculturalmente estabelecidas entre os moradores do rio Unini, Parque Nacional do Jaú, Amazônia central, com o conjunto da fauna silvestre local. Analisa a diversidade dessas interações e a reprodução das mesmas quando influenciadas por fatores de gênero e geração. Os procedimentos metodológicos adotados foram observação participativa e oficinas de grupos focais. Nessas oficinas, foram produzidas free-listings de animais silvestres relacionados a um determinado habitat. O grau de similaridade e dissimilaridade entre as listas foi analisado utilizando-se o Índice de Jaccard, ilustrado em dendrogramas. de maneira geral, as associações mentais entre elementos da fauna, habitat da floresta e nichos ecológicos que expressam as interações socioculturais dos indivíduos com os animais silvestres são bastante similares entre os membros da comunidade. No entanto, os efeitos de geração e de gênero são perceptíveis. A reprodução dessas interações perpassa pela questão do habitus, que estrutura o processo de socialização das interações culturais com a fauna local.

Quadros em movimento: O uso das fontes iconográficas no filme Os Bandeirantes (1940), de Humberto Mauro

Este artigo discute a utilização das fontes iconográficas enquanto estratégia de autenticação da narrativa cinematográfica através da análise de um dos blocos narrativos do filme Os Bandeirantes (1940), de Humberto Mauro. Tal filme teve a orientação geral de Edgar Roquette-Pinto, diretor presidente do Instituto Nacional de Cinema Educativo (INCE), e a coordenação histórica de Afonso de Taunay, historiador e diretor do Museu Paulista, mais conhecido como Museu do Ipiranga. A estratégia de utilização da iconografia enquanto documento histórico em Os Bandeirantes produzirá um curto-circuito com o trabalho de mise-en-scène de Humberto Mauro, gerando significados diversos daqueles que foram idealizados pelos produtores do filme.
