Investigação e avaliação da toxicidade aguda dos agrotóxicos mais utilizados no cinturão verde da Grande Natal (RN, Brasil) para o peixe-zebra (Danio rerio Hamilton Buchanan, 1822, Teleostei, Cyprinidae

The objectives of this research were to investigate the agrotoxic most used in the Gramorezinho region in the green belt of Natal, and to evaluate the acute toxicity of these, based on the LC50-48h values estimated in tests for Danio rerio, internationally used as test organism. The acute toxicity tests were performed under laboratory conditions, according to standardized methods (ABNT/NBR/15088/04) for this species. The LC50-48h estimated to Tamaron BR was 352.89 mg.L-1, which characterizes that as practically non-toxic, according to toxicological classes cited by Zucker. For Decis 25EC, the LC50-48h estimated was 0.0004156 mg.L-1 (4.156 X 10-4 mg.L-1), which classifies it as highly toxic to this species

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

Poder local e o funcionamento do comércio vicinal na cidade de São Paulo (1765-1822)

Este texto apresenta algumas hipóteses e idéias sobre o comércio de abastecimento da cidade de São Paulo, entre os anos 1765-1822, através de dados quantitativos e qualitativos levantados em dois conjuntos documentais produzidos pelo Senado da Câmara: Atas e Papéis Avulsos. Este comércio é entendido como um dos circuitos do organismo colonial, conforme proposto por José Roberto do Amaral Lapa. Neste sentido, vem sendo constatado seu funcionamento autônomo, de acordo com os fluxos do mercado interno, as ações dos negociantes-arrematadores de contratos e as reações do Senado da Câmara de São Paulo para enfrentar seus contextos de crise e a radicalização de relações de poder em torno deste circuito mercantil, como fator desencadeador de disputas e hostilidades entre interesses políticos locais, negociantes-arrematadores e autoridades régias.

Subsistemas de comércio costeiros e internalização de interesses na dissolução do Império Colonial português (Santos, 1788-1822)

Discutem-se os primeiros resultados de uma pesquisa sobre o comércio costeiro e suas relações com o funcionamento do sistema colonial e com o contexto da Independência. A tese é de que em portos menores da costa da capitania de São Paulo, como em Santos, havia um grupo de comerciantes que atuava efetivamente no comércio costeiro e defendeu seus interesses de exclusividade de participação nesse setor contra a presença de comerciantes externos à vila. A discussão apoia-se em documentos da alfândega de Santos, como mapas de exportação-importação, mapas de embarcações, ofícios de governadores e juízes da alfândega e requerimentos de negociantes estrangeiros.

O império da lei: ensaio sobre o cerimonial de sagração de D. Pedro I (1822)

Ce texte analyse le cérémonial royal de la monarchie constitutionnelle brésilienne: le sacre et le couronnement de l'Empereur D. Pedro I. Notre examen de ce cérémonial a comme point de départ son caractère liturgique, pour comprendre pourquoi cet aspect a été considéré essentiel alors pour affirmer l'autonomie du nouveau royaume et, en même temps, a contribué pour définir le pouvoir politique de l'Empire du Brésil.

Utilization of shells of the snail Achatina fúlica Bowdich, 1822 (Mollusca, Gastropoda) by the hermit crab Clibanarius vittatus (Bosc, 1802) (Decapoda, Anomura) in the São Vicente Estuary, São Paulo, Brazil

Hermit crabs depend on mollusc shells for housing. In this study, an unusual resource is reported for a hermit crab that usually inhabits marine gastropod shells. During a field study conducted from May 2001 to April 2003 in an estuarine area in São Vicente, state of São Paulo, Brazil, 21 individuals of Clibanarius vittatus (Bosc, 1802) were found inhabiting the shells of the terrestrial gastropod Achatina fullea Bowdich, 1822. A. fúlica occurs in nearshore grass patches, where occasional contact with sea water kills them, and their shells then become available to the hermit crabs.
