Gonadal development in the freshwater crab Sylviocarcinus pictus (H. Milne Edwards, 1853) (Brachyura: Trichodactylidae) from the Guamá river, state of Pará, Brazil

Os estádios de desenvolvimento das gônadas de machos e fêmeas de caranguejos Sylviocarcinus pictus (H. Milne Eduards, 1853) foram descritos por meio de observações macroscópicas e microscópicas (técnica histológica). A descrição histológica foi baseada em 40 espécimes (20 de cada sexo). Foram identificados quatro estádios de desenvolvimento para as fêmeas: imaturo, em maturação, maturo e em reabsorção. As seguintes células foram encontradas: ovogônias, ovócitos em vitelogênese inicial, ovócitos em vitelogênese avançada, células foliculares e folículos pós-ovulatórios. Três estádios de desenvolvimento foram encontrados para os machos: imaturo, em maturação e maturo, com indicação de: espermatogônias, espermatócitos, espermátides, espermatozóides e espermatóforos. Tais dados sugerem o padrão descrito na literatura. O tamanho da maturidade sexual foi de 32,3 mm de largura da carapaça para machos e 31,5 mm para fêmeas. Os estádios gonadais observados macroscopicamente por meio do volume e da coloração das gônadas foram validados pela análise histológica, sendo um critério útil e ágil para a identificação da maturidade sexual para a espécie. O presente estudo oferece informações inéditas sobre a biologia reprodutiva de Sylviocarcinus pictus.

Daquilo que se come: uma história do abastecimento e da alimentação em Belém (1850-1900)

Esta dissertação compreende a história da alimentação em Belém entre o período de 1850-1900, analisando o processo de abastecimento da cidade de Belém, suas relações com os interiores da Província, com os outros países e ainda com outras Províncias do Império ressaltando os produtos mais comercializados e consumidos na cidade. Por outro lado a economia crescente da borracha possibilitou que a cidade de Belém conhecesse importantes transformações urbanas e demográficas, permitindo uma análise dos lugares de comer e seus diversos sujeitos sociais que figuravam as ruas, restaurantes, padarias e outros estabelecimentos alimentícios.

Marques de Carvalho na imprensa periódica belenenses oitocentistas (1800-1900)

O escritor, político, jornalista e diplomata paraense João Marques de Carvalho nasceu em Belém, capital do estado do Pará, no dia 6 de novembro de 1866, e faleceu em Nice, no sul da França, no dia 11 de abril de 1910, aos 43 anos. Além de parte de sua prosa de ficção publicada em livro, alguns de seus textos, entre contos, romances, lendas e ensaios críticos, encontram-se dispersos em páginas de determinadas folhas periódicas que circularam por Belém nas duas últimas décadas do século XIX (1880-1900), como o Diário de Belém, A Província do Pará, A República e A Arena. Considerando, portanto, esse universo de escritos divulgados em jornais locais, objetiva-se, com este trabalho, avaliar não apenas como Marques de Carvalho compreendeu a doutrina naturalista, a função da crítica e a produção literária no estado do Pará, como também analisar a representação do espaço ficcional lusitano e amazônico em seus contos e romances publicados na imprensa periódica belenense oitocentista.

A produção da "música cabocla": a polifonia formadora do Carimbó nas representações de literatos, jornalistas e folcloristas no Pará (1900-1960)

Este texto aborda o percurso histórico de debates artísticos e intelectuais desenvolvidos em torno da transformação do carimbó em expressão típica da musicalidade cabocla do Pará e da Amazônia. O intercâmbio de ideias entre folcloristas, jornalistas e escritores promoveu, entre 1900 e 1960, os sentidos que se articularam em torno da ideia do carimbó como manifestação folclórica tipicamente regional.

A presença da literatura/cultura portuguesas em periódicos paulistas - 1900-1922

Partindo-se do pressuposto de que existe uma interligação, por meio da presença da literatura/cultura portuguesa, entre Portugal e a cidade de São Paulo – no período de 1900-1922, caracterizado ainda como pré-modernista brasileiro –, a proposta deste texto dirige-se ao comentário de alguns periódicos (O Estado de S. Paulo; A Vida Moderna; O Pirralho), visto que “[...] há uma história da literatura que se projeta na cidade de S. Paulo; e há uma história da cidade de S. Paulo que se projeta na literatura.” (CANDIDO, 1975). Assim, pretende-se verificar como a presença da literatura/cultura portuguesa (principalmente autores canônicos do século XIX) repercutiu na vida social e intelectual da cidade de São Paulo, para melhor compreensão das formas de sociabilidade, bem como a caracterização das diferentes etapas percorridas pela literatura brasileira em São Paulo.

Clíticos e preposições: a norma e o normal em jornais paulistas (1900 a 1915)

Based on the assertions of the Theory of Linguistic Variation and Change, this paper proposes a discussion about the possible action of linguistic norms over two variable phenomena in Brazilian Portuguese: the position of clitic pronouns associated with a single verb, and the use of prepositions with verbal complements indicating a ?goal/recipient?. By the analysis of data from the newspapers from São Paulo and Rio Claro between (the years of) 1900 and 1915, we intend to describe each phenomenon; compare these descriptions and evaluate the role played by the standard and the common usage which is (already) perceptible in the ?paulistas? continuous published pages of that period.

Population biology of Excirolana armata (Dana, 1853) (Isopoda, Cirolanidae) on an exposed sandy beach in Southeastern Brazil

The reproductive biology and population dynamics of the cirolanid isopod Excirolana armata (Dana, 1853) were analysed through monthly samples from December 2003 to November 2005 on Una beach, Sao Paulo state (24 degrees S), in Southeastern Brazil. Sampling was performed along three transects established from the base of foredunes to the waterline. On Una beach, E. armata showed continuous reproduction with higher abundances of ovigerous females in winter and spring (July-November) with a higher peak of juveniles in spring (November 2004). The fecundity ranged from 2 to 18 eggs/embryos per female, depending on the female length. The incubation period was estimated as 2 months. The life span of males and females was nearly 1 year. The short life span and the high energetic expenditure inherent to reproduction with maternal care, probably kept females from producing more than one brood in their lifetime. When comparing the population of E. armata on Una beach (24 degrees S) with populations in Southern Brazil (32 degrees S), Uruguay (34 degrees S) and Argentina (36 degrees S), it was verified that several biological population traits (length of the smallest juvenile, length of the largest individual, length of the smallest and largest ovigerous females, range of fecundity and life span) tended to increase at higher latitudes, whereas other traits (instantaneous rate of mortality and the curvature parameter of von Bertalanffy growth function) tended to decrease. However, comparing E. armata on Una beach (24 degrees S) with a population situated at a close latitude (25 degrees S), unexpected differences in relation to population structure and to growth demonstrated and reinforced the importance of density-dependent factors over life history traits of E. armata on dissipative beaches.

Production of Excirolana armata (Dana, 1853) (Isopoda, Cirolanidae) on an exposed sandy beach in southeastern Brazil

The somatic and gonad productions of the cirolanid isopod Excirolana armata were analyzed by taking monthly samples from December 2003 to November 2005 on Una beach, So Paulo state (24A degrees S), southeastern Brazil. Sampling was performed along three fixed transects established from the base of the foredunes to the waterline. Weight-specific growth rate was used to estimate the E. armata somatic production for 2004 and 2005, separately. The gonad production was estimated based on the monthly reproductive potential (mean number of eggs/embryos per female x monthly abundance of ovigerous females with near-release broods) for 2004. The annual somatic production of E. armata population varied from 15.57 to 17.25 g AFDW m(-1) year(-1) and the somatic production/biomass ratio (P (s)/B) from 3.55 to 3.14 year(-1) for 2004 and 2005, respectively. The P (s)/B ratios were higher for males (4.02 and 3.19 year(-1) for 2004 and 2005) than for females (3.10 year(-1) for both years). The annual gonad production (P (g) = 1.07 g AFDW m(-1) year(-1)) contributed about 15 and 6% to the total production (P (s) + P (g)) of females and the population, respectively. The proportion of gonad to somatic production of females (P (g)/P (s)) increased with individual size (ca 90% in the 7.5 mm size class), and the annual weight-specific gonad production (P (g)/B ratio) was estimated to 0.24 year(-1). The high P (s)/B ratios estimated for E. armata derive from the fast growth of individuals and show the importance of this population to the energy flow on Una beach ecosystem. However, the low percentage of juveniles verified in this population and in other studies of populations of the genus Excirolana is discussed as an important source of underestimation of P (s)/B ratio.

Description of the larva of Mnesarete pudica (Hagen in Selys, 1853) (Odonata: Calopterygidae) and notes on known genera of South American Calopterygidae larvae

The final instar larva of Mnesarete pudica is described and illustrated based on reared specimens collected in Brazil. This species can be distinguished from others by presenting: a) five palpal and three premental setae; b) no posterodorsal hooks on abdominal segments; c) lateral spines only in S9-10. M. pudica is compared to other South American calopterygids and biological notes are presented.

The Social City : Middle-way approaches to housing and sub-urban golvernmentality in southern Stockholm, 1900-1945

This dissertation deals with the period bridging the era of extreme housing shortages in Stockholm on the eve of industrialisation and the much admired programmes of housing provision that followed after the second world war, when Stockholm district Vällingby became an example for underground railway-serviced ”new towns”. It is argued that important changes were made in the housing and town planning policy in Stockholm in this period that paved the way for the successful ensuing period. Foremost among these changes was the uniquely developed practice of municipal leaseholding with the help of site leasehold rights (Erbbaurecht). The study is informed by recent developments in Foucauldian social research, which go under the heading ’governmentality’. Developments within urban planning are understood as different solutions to the problem of urban order. To a large extent, urban and housing policies changed during the period from direct interventions into the lives of inhabitants connected to a liberal understanding of housing provision, to the building of a disciplinary city, and the conduct of ’governmental’ power, building on increased activity on behalf of the local state to provide housing and the integration and co-operation of large collectives. Municipal leaseholding was a fundamental means for the implementation of this policy. When the new policies were introduced, they were limited to the outer parts of the city and administered by special administrative bodies. This administrative and spatial separation was largely upheld throughout the period, and represented as the parallel building of a ’social’ outer city, while things in the inner ’mercantile’ city proceeded more or less as before. This separation was founded in a radical difference in land holding policy: while sites in the inner city were privatised and sold at market values, land in the outer city was mostly leasehold land, distributed according to administrative – and thus politically decided – priorities. These differences were also understood and acknowledged by the inhabitants. Thorough studies of the local press and the organisational life of the southern parts of the outer city reveals that the local identity was tightly connected with the representations connected to the different land holding systems. Inhabitants in the south-western parts of the city, which in this period was still largely built on private sites, displayed a spatial understanding built on the contradictions between centre and periphery. The inhabitants living on leaseholding sites, however, showed a clear understanding of their position as members of model communities, tightly connected to the policy of the municipal administration. The organisations on leaseholding sites also displayed a deep co-operation with the administration. As the analyses of election results show, the inhabitants also seemed to have felt a greater degree of integration with the society at large, than people living in other parts of the city. The leaseholding system in Stockholm has persisted until today and has been one of the strongest in the world, although the local neo-liberal politicians are currently disposing it off.
