Quando a fotografia (já) fazia os antropólogos sonharem: O jornal La Lumière (1851-1860)

Na efervescente metade do século XIX, marcada pela febre da ordem e do progresso, da racionalidade e das luzes, os antropólogos-naturalistas franceses descobrem, ao lado de muitos outros cientistas, as possibilidades heurísticas que a fotografia ofereceria à "visão" que eles tinham da "antropologia", a saber essa tentativa de mapeamento da "espécie humana", das raças e, dentre elas, dos tipos humanos, numa perspectiva claramente evolucionista. O jornal La Lumière (1851-1867), primeira publicação francesa dedicada à "Fotografia, às Artes e às Ciências", foi parcialmente reimpresso em 1995. Mergulhando nas colunas desse semanário, o leitor, além de adquirir uma idéia das origens da antropologia francesa, descobre as profissões de fé que se erguem em torno do novo suporte técnico e da nova "retina do cientista". Descobre, também, como essa prótese instaura uma nova ordem do olhar e levanta, em termos de uma epistemologia do conhecimento, um interessante questionamento em torno de dois outros meios de representações figurativas nos círculos antropológicos da época: os desenhos e as moldagens.

A disparada do burro e a cartilha do feitor: lógicas morais na construção de redes de sociabilidade entre escravos e livres em fazendas do Sudeste, 1860-1888

O objetivo principal do autor é pensar as relações de trabalho entre senhores, escravos, lavradores, administradores e feitores, em fazendas de café do Sudeste, nas décadas finais da escravidão. Para isso, tais relações sociais são analisadas através de dois estudos de caso, nos quais se chama a atenção para o conflito entre homens livres e escravos na formação de alianças em torno das regras sociais de justiça e trabalho, as quais são constantemente rompidas e reafirmadas, em permanente conflito social.

Cephalopoda as prey of juvenile Southern elephant seals at Isla 25 de Mayo/King George, South Shetland Islands

The aim of the present study was to enhance the knowledge of the feeding habits of the juvenile component of the population of Southern elephant seals [Mirounga leonina (Linnaeus, 1758)] from Isla 25 de Mayo, South Shetland Islands, age class whose diet information is scarce. A total of 60 individuals were stomach lavaged in the spring - summer seasons of three consecutive years (2003, 2004 and 2005) of which 53.3 % (n = 32) presented food remnants. The Antarctic glacial squid Psychroteuthis glacialis Thiele, 1921 was the dominant prey taxon in terms of frequency of occurrence (68.7%), numerical abundance (60.1%) and biomass (51.5%), contributing 84.1% to the total relative importance index. Other squid prey species of importance were Slosarczykovia circumantartica Lipinski, 2001 in terms of occurrence (37.5%) and numerical abundance (14%) and Moroteuthis knipovitchi Filippova, 1972 in terms of biomass (16%). All identified cephalopod prey taxa are distributed south of the Antarctic Polar Front, except for the squid Martialia hyadesi Rochebrune & Mabille, 1889 which has a circumpolar distribution associated to the Polar Frontal Zone. No significant differences in the sizes of P. glacialis preyed upon by elephant seals were found between sexes and years. However, significant interannual differences were found in the taxonomical composition of their diet. This would be associated with temporal changes in food availability at the foraging areas of seals, which in turn may have been influenced by changes in oceanographic conditions as a result of the El Niño Southern Oscillation (ENSO) phenomenon that occurred during part of the study period. Furthermore, a differential response of males and females to this temporal variation was observed, with the former being also associated to a predation on octopods. This would suggest a sexual segregation in foraging habits of this species from the early stages of its life cycle.

Sobre Dipetalonema spiralis (Molin, 1860) (Nematoda, Filarioidea)

The authors give a description of Dipetalonema spiralis (Molin, 1860), based on two samples collected by the C. E. E. L. V. A. in the joints of the hands and feet of Choloepus didactylus (L.) at Piratuba, State of Pará, Brazil, both containing males and females. A study of the literature is made and original drawings are presented.

Colonization by mites of glacier-free areas in King George Island, Antarctica

This work aimed to investigate the ratio of colonization by terrestrial mites on ice-free areas created by the ongoing climate-induced melting of Antarctic glaciers. Glacier retreat opens new ice-free areas for the colonization by vegetation and animals. The study was undertaken on the Antarctic Specially Protected Area no. 128 (West Coast of the Admiralty Bay, King George Island, South Shetlands Islands). Transects marked between the Ecology, Baranowski and Windy Glaciers, and a sea shore were used to collect soil samples. Oribatid mites were found only on near-shore areas, on patches of vegetation of more than 30 years of age. The colonization by mite communities is strongly determined by the presence of plants.

O médico George Thomson e os primeiros desenvolvimentos do conceito de gás

The word gas was coined by the "chemical philosopher" Joan Baptista Van Helmont (1579 -- 1644) to name a very broad concept in his chemico-medical system. Eventually, some physicians who followed Helmontian ideas adopted the concept. The present paper aims to analyze the reception of the original idea of gas by an English Helmontian physician, George Thomson (1619 -- 1677). Thomson wrote that the "material cause" of the plague was a gas, and compared it to the "Gas of sulphur". He also related the human archeus to a gas, and explained some observations in the laboratory in terms of production of gases. We observe, however, that Thomson was not as interested as Van Helmont in discussing details about the structure of the matter. Thus, gas did not have the same relevance in Thomson's work as it had in Van Helmont's.
