A Produção do Flagelo : a re-produção do espaço social da seca na cidade de Mossoró (1877-1903-1915)

The great droughts re- produced spaces in the city of Mossoró / RN in the end of the nineteenth century to the beginning of the twentieth century. Its dimension exceeds the climatic effects becoming social locus when advances over the political and economic sectors, social and cultural of the North / Northeast Brazilian societies during that period. This way, analyzing the re-production of social space in episodes of Mossoró‟s droughts is our toil. So try to reveal each segment, route and aspect of production of space in its size and interface between the perceived, conceived and lived, and subjects related to it - refugees, population and authorities - during the droughts of 1877, 1903 and 1915 within Mossoró city. Therefore, issues such as the constitution and representation of the city and social space in the terrifying experience of the drought of 1877, the production of fixed objects and flows of the urban web through of migrant labor, attempts to control, discipline and spatial planning and ways to resistance to these charges in daily sphere are key issues addressed in this work. For this we use diverse sources as minutes of the city council, reports from provincial presidents, media, memory books and others that sustain us in building our narrative and problematic. This way, the spatial production of Mossoró‟s droughts reveals itself in the field of relations and political-economic transformations and sociocultural, inextricably, that shapes and mobilizes your own social space

A new Moenkhausia Eigenmann, 1903 (Ostariophysi: Characiformes) from Chapada Diamantina, rio Paraguaçu Basin, Bahia, Northeastern Brazil

Moenkhausia diamantina, nova espécie, é descrita de tributário do rio Paraguaçu, BA, nordeste do Brasil. Esta espécie é distinguida das demais congêneres por caracteres relacionados ao padrão de coloração do corpo, pela presença de escamas na linha mediana pré-dorsal e número de raios da nadadeira anal.

Size variation in the grapsid crab Aratus pisonii (H. Milne-Edwards, 1837) among populations of different subtropical mangroves

Size variation in the adult population of the grapsid crab Aratus pisonii (H. Milne-Edwards, 1837) was studied by comparing median values obtained from six different populations from nearby mangrove areas. The mangrove structure at those sites was also examined and related to size differences among populations. Disregarding sex, crab size is apparently related to the mangrove structure. Smallest and largest crab sizes were recorded at the sites where tree density and tree diameter were minimum and maximum, respectively. Estimates of size at the onset of maturity, considering the size of the smallest ovigerous female, followed the same trend. These results support the hypothesis that average crab size and size at the onset of maturity can be associated to mangrove productivity.

Reproductive biology of Atlantoraja cyclophora (Regan 1903) (Elasmobranchii : Rajidae) off southern Brazil

A total of 459 (245 females, 214 males) Atlantoraja cyclophora was captured by bottom trawl off the coast of Rio Grande do Sul between 30 degrees 40'S and 34 degrees 30'S during surveys conducted in winter 2001 and summer/autumn 2002 at depths of 100-300 M. Total length at maturity was 52.8 cm for females and 48.5 cm for males. Symmetry and functional parity of the gonads were observed in both sexes, but there was no significant temporal variation in either sex for any of the reproductive parameters studied. Ovulation and egg-deposition were similarly intensive in both seasons. In adult females, there was an ovarian resting period at an individual level, though it was not synchronized at a population level. Distribution of egg-bearing females was not related to depth or species' range. (c) 2005 International Council for the Exploration of the Sea, Published by Elsevier Ltd. All rights reserved.

Sexual development and reproductive cycle of the Eyespot skate Atlantoraja cyclophora (Regan, 1903) (Chondrichthyes: Rajidae: Arhynchobatinae), in southeastern Brazil

Specimens o/Atlantoraja cyclophora were collected monthly from commercial fishing landings at Guarujá, São Paulo State, Brazil, from March 2005 to April 2006 at depths between 10 and 146 m. Males ranged from 13.3 to 58.5 cm TL (n = 396). Both the smallest mature male and the largest immature male were 47.0 cm long. Males' size-at-50% maturity was calculated to be 46.3 cm. Females ranged from 11.5 to 68.0 cm (n = 401). The smallest mature and the largest immature female were 51.6 and 53.0 cm long respectively. For the females, size-at-50% maturity was calculated to be 53.2 cm. In the males the hepatosomatic andgonadosomatic indices varied between 0.48 (August) and 3.54 (November) and between 0.15 (November) and 1.45 (June) respectively, with no significant variation for the fourteen-month period. In the females the hepatosomatic and gonadosomatic indices varied from 1.55 and 6.30 3.54 (both for April 2006) and from 0.08 (December) to 4.41 (October) respectively, with no significant difference among months. Egg-bearing females were found in all months with proportions varying from 0.03 (March) to 0.67 (April). Both males and females undergo an annual cycle, with slight seasonal variations in reproductive activity and a peak in the proportion of egg bearing females between April and July.

Tendencies to explicitation in 'A Legião Estrangeira' translated into English with the tittle The Foreign Legion by Giovanni Pontiero

Some aspects involving explicitness within the literary translation process from Portuguese into English are analyzed. Clarice Lispector's 'A Legião Estrangeira' and its translation by Giovanni Ponteiro as The Foreign Legion, have been selected for current investigation employing the theoretical and methodological approach based on Baker's Corpus-based Translation Studies (1993, 1995, 1996, 2000) and Berber Sardinha's Corpus Linguistics (2004). The interrelations between the original and the translated texts and Ponteiro's solutions in his translation of preferential and recurring terms and idiomatic expressions are underscored and discussed.

The reproductive cycle of the male sleep snake Sibynomorphus mikanii (Schlegel, 1837) from southeastern brazil

This study describes the male reproductive cycle of Sibynomorphus mikanii from southeastern Brazil considering macroscopic and microscopic variables. Spermatogenesis occurs during spring-summer (September-December) and spermiogenesis or maturation occurs in summer (December-February). The length and width of the kidney, the tubular diameter, and the epithelium height of the sexual segment of the kidney (SSK) are larger in summer-autumn (December-May). Histochemical reaction of the SSK [periodic acid-Schiff (PAS) and bromophenol blue (BB)] shows stronger results during summer-autumn, indicating an increase in the secretory activity of the granules. Testicular regression is observed in autumn and early winter (March-June) when a peak in the width of the ductus deferens occurs. The distal ductus deferens as well as the ampulla ductus deferentis exhibit secretory activities with positive reaction for PAS and BB. These results suggest that this secretion may nourish the spermatozoa while they are being stored in the ductus deferens. The increase in the Leydig cell nuclear diameter in association with SSK hypertrophy and the presence of sperm in the female indicate that the mating season occurs in autumn when testes begin to decrease their activity. The peak activity of Leydig cells and SSK exhibits an associated pattern with the mating season. However, spermatogenesis is dissociated of the copulation characterizing a complex reproductive cycle. At the individual level, S. mikanii males present a continuous cyclical reproductive pattern in the testes and kidneys (SSK), whereas at the populational level the reproductive pattern may be classified as seasonal semisynchronous. © 2012 Wiley Periodicals, Inc.

An assessment approach for application of spermatic data in phylogenetic analyses: Within the genus Moenkhausia Eigenmann, 1903 (Characiformes: Characidae)

Spermiogenesis and sperm ultrastructure from 21 species of Moenkhausia and others related genera are described. To evaluate the phylogenetic signals, 18 unordered characters were utilized in implied weighting analysis through the program TNT 1.1. Four variations of spermiogenesis were found. In the earliest spermatids, the nucleus can be positioned lateral, eccentric, strongly eccentric or nearly medial in relation to the distal centriole. The nuclear rotation can be present or absent. These spermiogenesis processes are related or intermediate to Type I and Type III. Taking into account the degrees of nuclear rotation during the spermiogenesis and other characteristics, distinct forms of spermatozoa are observed among the species analyzed. The phylogenetic analysis yielded a single most parsimonious tree with fit value 2.70000 and the topology obtained founds Moenkhausia as non-monophyletic. However, some hypothesis of relationships previously proposed viz the clade 20, which contains the type species Moenkhausia xinguensis, is recovered herein. This clade is supported by five synapomorphies, and it allows the supposition that these species constitute a monophyletic group. The whole topology is presented and discussed. © 2012 The Authors.

Análise da variação morfológica de Dipsas catesbyi (Sentzen, 1796) e Dipsas pavonina Schlegel, 1837 (Serpentes: Colubridae: Dipsadinae)

A subfamília Dipsadinae engloba 22 gêneros da fauna de colubrídeos neotropicais e 24 outros considerados incertae sedis, mas com caracteres comuns aos dipsadíneos. Os gêneros Dipsas, Sibon, Sibynomorphus e Tropidodipsas formalmente compõem a tribo Dipsadini a qual é considerado um grupo monofilético bem fundamentado. A tribo é caracterizada por serpentes que apresentam um alto grau de especialização morfológica, relacionado ao modo de alimentação e adaptações ao hábitat em que vivem. O gênero Dipsas inclui aproximadamente 32 espécies, distribuídas do México até a América do Sul, é constituído por serpentes de corpo delgado e alongado, com cabeça curta e proeminente, olhos grandes, pupilas verticais e ausência de sulco mentoniano. As espécies são notavelmente variáveis na coloração, número de escamas e outros caracteres morfológicos. Essa extrema variação tem dificultado a definição dos limites entre as espécies e a interpretação de padrões de variação geográfica. A grande variação morfológica dos caracteres presentes nas espécies D. catesbyi e D. pavonina, associada à dificuldade de identificação dos táxons e à escassez de informações sobre as suas distribuições geográficas, justificam a necessidade de uma análise mais detalhada destas espécies. Para tal, o presente estudo foi dividido em dois capítulos. O primeiro capítulo corresponde à análise da variação individual, sexual e geográfica de D. catesbyi e D. pavonina, e a comparação dos caracteres morfológicos entre as duas espécies. O segundo corresponde à análise da macroestrutura das glândulas cefálicas nestas duas espécies, relacionando-as com outros táxons de Dipsadinae.

Filogenia molecular e taxonomia do grupo Anolis chrysolepis Duméril & Bibron, 1837 (Squamata, Polychrotidae)

A Amazônia é considerada a maior floresta tropical contínua do mundo e diversos mecanismos têm sido propostos para tentar explicar a sua alta diversidade biológica. Um dos mecanismos mais discutidos desde sua proposição é a hipótese dos Refúgios, que se baseia na retração da floresta em períodos mais secos, isolando a fauna de florestas em refúgios imersos em uma matriz de vegetação aberta. Essas retrações e subseqüentes expansões em períodos mais mésicos provocariam a interrupção do fluxo gênico entre as populações isoladas e poderiam gerar especiação. Contudo, estudos moleculares recentes indicam que a diversificação de espécies de vertebrados de florestas tropicais provavelmente precede o período pleistocênico, originalmente indicado na hipótese dos Refúgios como o período em que esses eventos teriam ocorrido. A espécie politípica Anolis chrysolepis, juntamente com Anolis bombiceps, foi previamente estudada como um típico exemplo de diversificação gerada pelas flutuações climáticas do Pleistoceno, embora estudos posteriores tenham domonstrado a presença de grande divergência molecular entre parte das subespécies, indicando uma separação mais antiga desses táxons e levantando o questionamento sobre seu status taxonômico. Utilizamos o gene mitocondrial ND2 para investigar as relações filogenéticas entre as subespécies de Anolis chrysolepis e os táxons determinados em estudos anteriores como mais próximos a elas. Além disso, a sua morfologia e o seu status taxonômico foram revisados, a fim de verificar a congruência entre os dados morfológicos e moleculares, determinando se os táxons previamente reconhecidos morfologicamente são espécies válidas. Com base nos dois conjuntos de dados, nós elevamos as cinco subespécies do grupo Anolis chrysolepis ao status de espécies, diagnosticamos cada uma delas com comentários sobre as principais diferenças morfológicas entre as espécies irmãs e fornecemos novos dados de distribuição.
