Stock discrimination and movements of narrow-barred Spanish mackerel across northern Australia as indicated by parasites

The parasite fauna of Spanish mackerel Scomberomorus commerson from 10 sites across northern Australia and one site in Indonesia, was examined to evaluate the degree of movement and subsequent stock structure of the fish. Kupang fish (Indonesia) had very few Terranova spp.. Grillotia branchi, Otobothrium cysticum or Pterobothrium sp. compared to Australian fish, indicating that no Australian fish enter the Kupang fishery. Univariate and discriminant function analysis of four 'temporary' parasite species, the copepod Pseudocyenoides armatus and the monogeneans Gotocotyla bivaginalis, Pricea multae and Pseudothoracocotyla ovalis, demonstrated little similarity between areas of northern Australia, indicating minimal short-term exchange between neighbouring groups of S. commerson. Analyses of five 'permanent' parasite species, the larval helminths G. branchi, O. cysticum, Pterobothrium sp., Callitetrarhynchus gracilis and Paranybelinia balli, also revealed large differences between areas thus indicating long-term separation. There are at least six parasitological stocks across northern Australia: Fog Bay/Bathurst Island, Cape Wessel. Groote/Sir Edward Pellew. Mornington Island, Weipa. and the Torres Strait. The occurrence of a few irregular fish in the samples suggested that LIP to 5% of fish moved between stocks during their lifetime. The similarity of within-school variability to that between schools showed that the fish do not form long-term school associations. (C) 2003 The Fisheries Society of the British Isles.

Stratigraphy, facies architecture and tectonic implications of the Upper Devonian to Lower Carboniferous Campwyn Volcanics of the northern New England Fold Belt

Upper Devonian to Lower Carboniferous strata of the Campwyn Volcanics of east central Queensland preserve a substantial sequence of first-cycle volcaniclastic sedimentary and coeval volcanic rocks that record prolonged volcanic activity along the northern New England Fold Belt. The style and scale of volcanism varied with time, producing an Upper Devonian sequence of mafic volcano-sedimentary rocks overlain by a rhyolitic ignimbrite-dominated sequence that passes upward into a Lower Carboniferous limestone-bearing sedimentary sequence. We define two facies associations for the Campwyn Volcanics. A lower facies association is dominated by mafic volcanic-derived sedimentary breccias with subordinate primary mafic volcanic rocks comprising predominantly hyaloclastite and peperite. Sedimentary breccias record episodic and high energy, subaqueous depositional events with clastic material sourced from a mafic lava-dominated terrain. Some breccias contain a high proportion of attenuated dense, glassy mafic juvenile clasts, suggesting a syn-eruptive origin. The lower facies association coarsens upwards from a lithic sand-dominated sequence through a thick interval of pebble- to boulder-grade polymict volcaniclastic breccias, culminating in facies that demonstrate subaerial exposure. The silicic upper facies association marks a significant change in eruptive style, magma composition and the nature of eruptive sources, as well as the widespread development of subaerial depositional conditions. Crystal-rich, high-grade, low- to high-silica rhyolite ignimbrites dominate the base of this facies association. Biostratigraphic age controls indicate that the ignimbrite-bearing sequences are Famennian to lower-mid Tournaisian in age. The ignimbrites represent extra-caldera facies with individual units up to 40 m thick and mostly lacking coarse lithic breccias. Thick deposits of pyroclastic material interbedded with fine-grained siliceous sandstone and mudstone (locally radiolarian-bearing) were deposited from pyroclastic flows that crossed palaeoshorelines or represent syn-eruptive, resedimented pyroclastic material. Some block-bearing lithic-pumice-crystal breccias may also reflect more proximal subaqueous silicic explosive eruptions. Crystal-lithic sandstones interbedded with, and overlying the ignimbrites, contain abundant detrital volcanic quartz and feldspar derived from the pyroclastic deposits. Limestone is common in the upper part of the upper facies association, and several beds are oolitic (cf. Rockhampton Group of the Yarrol terrane). Overall, the upper facies association fines upward and is transgressive, recording a return to shallow-marine conditions. Palaeocurrent data from all stratigraphic levels in the Campwyn Volcanics indicate that the regional sediment-dispersal direction was to the northwest, and opposed to the generally accepted notion of easterly sediment dispersal from a volcanic arc source. The silicic upper facies association correlates in age and lithology to Early Carboniferous silicic volcanism in the Drummond (Cycle 1) and Burdekin Basins, Connors Arch, and in the Yarrol terranes of eastern Queensland. The widespread development of silicic volcanism in the Early Carboniferous indicates that silicic (rift-related) magmatism was not restricted to the Drummond Basin, but was part of a more substantial silicic igneous province.

Birth in the northern quoll, Dasyurus hallucatus (Marsupialia : Dasyuridae)

Birth has been observed in a number of marsupial species and, in the studies to date, the newborn have crawled up to or across to the pouch. The method of birth in the quoll, a dasyurid, differs greatly from that observed in other marsupials. Births were recorded at normal speed using hand-held digital video cameras. Birth was heralded by a release of about 1 mL of watery fluid from the urogenital sinus followed by gelatinous material contained in either one or two tubes emanating from the sinus. The newborn, still encased in their placental membranes, were in the gelatinous material within a column. To exit this column, they had to grasp a hair and wriggle about 1 cm across to the pouch. In the pouch the newborn young had to compete for a teat. Although the quolls possessed 8 teats, the number of young in the pouch immediately after birth was 17, 16, 6, 16, 13 and 11 for each of the 6 quolls filmed. While birth has been described previously in another two dasyurids, the observers did not describe birth as reported here for the quoll. Nevertheless the movement of the newborn from the sinus to the pouch is so quick that this could have previously been missed. Filming birth from beneath and from the side allowed for a greater understanding of the birth process. Further studies are required to determine whether this use of a gelatinous material is part of the birth process in all dasyurids.

Mosquito host-feeding patterns and implications for Japanese encephalitis virus transmission in northern Australia and Papua New Guinea

Japanese encephalitis (JE) virus spread to northern Australia during the 1990s, transmitted by Culex annulirostris Skuse and other mosquitoes (Diptera: Culicidae). To determine the relative importance of various hosts for potential vectors of JE virus, we investigated the host-feeding patterns of mosquitoes in northern Australia and Western Province of Papua New Guinea, with particular attention to pigs, Sus scrofa L. - the main amplifying host of JE virus in South-east Asia. Mosquitoes were collected by CDC light traps baited with dry ice and 1-octen-3-ol, run 16.00-08.00 hours, mostly set away from human habitations, if possible in places frequented by feral pigs. Bloodmeals of 2569 mosquitoes, representing 15 species, were identified by gel diffusion assay. All species had fed mostly on mammals: only 30%) were trapped where domestic pigs were kept close to human habitation. From seven of eight locations on the Australian mainland, the majority of Cx. annulirostris had obtained their bloodmeals from marsupials, probably the Agile wallaby Macropus agilis (Gould). Overall proportions of mosquito bloodmeals identified as marsupial were 60% from the Gulf Plains region of Australia, 78% from the Cape York Peninsula and 64% from the Daru area of Papua New Guinea. Thus, despite the abundance of feral pigs in northern Australia, our findings suggest that marsupials divert host-seeking Cx. annulirostris away from pigs. As marsupials are poor JE virus hosts, the prevalence of marsupials may impede the establishment of JE virus in Australia.

Chemical characterisation of deep profile Ferrosols under sugarcane in wet tropical northern Queensland

The chemical properties of deep profile samples ( up to 12 m) of Ferrosols from northern Queensland were investigated to provide an understanding of the accumulation of nitrate ( NO3) within these soil profiles. The influence of other cations and anions present in the soil solution or on the exchange and the charge chemistry of the profiles were examined with respect to the NO3 accumulations. The major ions in the soil solution were Na, NO3, and chloride ( Cl). Distinct regions of anion accumulation were observed; SO4 accumulated in the upper profile of all cores, whereas NO3 and Cl accumulations were restricted to the lower profile of cores with appreciable AEC (> 1 cmol(c)/kg). Gaines-Thomas selectivity coefficients were used to indicate exchange preference for cations and anions, and are as follows: Al > Ca similar to Mg > K > Na and sulfate (SO4) > Cl similar to NO3. The selectivity of SO4 increased and the extractable SO4 decreased in the lower profile of all cores. This has important implications for the adsorption of NO3 and Cl. The NO3 and Cl accumulations were shown to correspond to a region of low SO4 occupancy of the exchange sites in the lower profile. Along with the high SO4 selectivity, this suggests that SO4 may control the positioning of the NO3 accumulations. It was concluded that the NO3 accumulations were relatively stable under current management practices, although the reduction in NO3 inputs would likely see the gradual replacement of NO3 with Cl as a result of their comparable selectivity for exchange sites.

O pátio jesuítico no Palácio Anchieta: narrativas tipomorfológicas e paisagísticas na cidade de Vitória (ES)

A hipótese defendida nesta pesquisa se baseia na possibilidade de a arquitetura jesuítica implantada em terras brasileiras (século XVI) dialogar e agenciar, num mesmo corpo edificado, e de modo inter-relacionado, aspectos relativos à morfologia urbana, tipologia e paisagem. Lama explica que, como disciplina, a morfologia urbana agrega para si não somente o ambiente construído, mas os meios pelos quais este foi construído em sua interação com a forma urbana, ou seja, os “fenômenos sociais, econômicos e outros motores da urbanização” (LAMAS, 1992). Entender a forma urbana é entender seus elementos constituintes, “quer em ordem à leitura ou análise do espaço, quer em ordem à sua concepção ou produção” (LAMAS, 1992). Estudar a forma urbana significa compreender o lugar onde se insere a cidade e seus elementos constituintes, seus espaços e a inter-relação entre eles e seu contexto, em um espectro abrangente do que se denomina cidade, e urbano. A tipologia arquitetônica e a morfologia urbana estão interligadas no cerne de suas análises, considerando que ambas, segundo Pereira, estudam “duas ordens de fatos homogêneos” (PEREIRA, 2012); estudam elementos constituintes da cidade – arquitetônicos e espaciais – que se sobrepõem ou se complementam de acordo com a escala de análise utilizada. A arquitetura jesuítica do Brasil colonial modela de modo determinante a construção de distintos núcleos urbanos originários na costa brasileira no século XVI. Isso, por meio da implantação de tipologia edilícia que acompanha a doutrina jesuítica de localização e escolha do sítio para suas construções, preconizando segurança, visibilidade do entorno e facilidade de acesso por rios ou pelo mar. Essas construções, realizadas em áreas elevadas, marcaram, por conseguinte, no tempo e no espaço, a paisagem dos primeiros núcleos urbanos brasileiros. A pesquisa analisou um dos exemplares históricos da arquitetura jesuítica no Estado do Espírito Santo, especificamente na cidade de Vitória, capital e núcleo urbano original da colonização portuguesa neste Estado. A instalação dos jesuítas na antiga Vila da Vitória, no séc. XVI, através de sua igreja dedicada a São Tiago e de seu colégio anexo, marca a presença tipológica de uma arquitetura religiosa que influencia a própria morfologia da cidade – caracterizando esta arquitetura como um tipomorfológico - e, por reflexo, participa da construção de sua paisagem urbana secular. Entende-se que o antigo complexo jesuítico de São Tiago e atual Palácio Anchieta, sede governamental e prédio cultural capixaba, é uma arquitetura que permeia estas três grandes narrativas arquitetônicas e urbanas: a tipologia, a morfologia e a paisagem.

A experiência de mulheres e a decisão pelo aborto provocado em uma região do Espírito Santo, Brasil

O escopo deste trabalho buscou compreender as percepções de mulheres que passaram pela decisão do aborto provocadona Microrregião de São Mateus (norte do estado do Espírito Santo, Brasil), a partir do percurso e das interações que se sustentaram nesse processo. Foram realizadas entrevistas com roteiro semiestruturado com sete mulheres sobre essa experiência no ambiente domiciliar dos sujeitos do presente estudo. Os dados foram colhidos em entrevistas abertas e foram analisados à luz do referencial teórico de autores que discorrem acerca do tema e também acerca da ciência bioética.O estudo apresenta seis categorias: O aborto na perspectiva da decisão íntima; o aborto como fonte de revelações de sentimentos; o contemplar peremptório da atitude;técnicas empregadas na intencionalidade e no ato de abortar; sustentando a decisão pelas relações comunitárias; e conteúdos e confidências femininas. A experiência das mulheres foi marcada poruma diversidade de sentimentos, como tristeza, culpa, arrependimento, desespero e dor emocional, todavia, também, pelo alívio com o fim da gravidez e do risco de morte. Angústia adicional foi condicionadaa partir da percepção de fatores contribuintes da decisão, como falta de condições financeiras, falta de apoio da família ou do parceiro e instabilidade no relacionamento com parceiro. Este estudo também sinalizou que o caráter cultural e histórico da gestação, no sentido da norma social, faz-se presente nas mulheres que vivenciam o aborto provocado; demonstrou que as mulheres do presente estudo encontram-se à margem das políticas públicas e de saúde; assinalou que os programas de planejamento familiar ou de saúde reprodutiva deveriam ser estruturados de forma a ajudar também a lidar com problemas de destituição social, econômica e educacional dessa população vulnerada, no sentido de que essas mulheres ultrapassem a proteção social básica e sejam amparadas por serviços de saúde, que constituam espaços equânimes de escuta, orientação e resolução.

Fluxos globais e intra-urbanos : subsídios para seu planejamento em Vitória

One is about a study of the interactions and conflicts between the distinct scales of the flows of the global production and urban mobility on the territory of the city, particularly of Vitória, Espírito Santo. From this analysis of the consequences of the new technologies of the information, of the communication and the transports on the economic and humans relations, if it considers the study of the characteristics of the two layers that act on the territory. Of the scale of the global production, the impacts of the great corporations, its physical nets and its force had been considered as territorial agent in the creation and sponsorship of plans. In the analysis of the place, the intra-urban movements of human displacements e had been considered, mainly the reasons of the trips. From the overlapping of the above-mentioned layers if it looked for to observe the interactions, conflicts and synergies between the layers the intervention in the flows demand of a coherent planning of the atract regions of trips, so that areas with infrastructure lack and services of public transport are not overloaded. Finally, as objective generality, generate with the basis in the interactions found in the overlapping, a list of subsidies for the planning of the urban flows.

Contradiction between the average age of retirement at the time of death and the average pension time for men and women in public employment in Portugal

The short article attempts to make some very brief reflections on the effects a lack of public policies positively discriminatory in terms of public employment retirement. In particular, the observation of the absurd contradiction between the average age of retirement at the time of death (for men and women) and the average pension time for men and women in public employment in Portugal.

Gender, wages, and productivity: an analysis of the tourism industry in northern Portugal

Tourism represents a major economic activity in Portugal, with an enormous wealth and employment growth potential. A significant proportion of jobs in the industry tourism are occupied by women, given that this industry is characterized by a relatively higher percentage of female employees. Despite the evidence of female progress with regard to their role in the Portuguese labor market, women continue to earn less than their male counterparts. This is clearly the case of the tourism industry, where statistics reveal a persistent gender wage gap. The objective of this paper is to provide empirical evidence on the determinants of gender wage inequality in the tourism industry in northern Portugal. Relying on firm-level wage equations and production functions, gender wage and productivity differentials are estimated and then compared. The comparison of these differentials allows inferring whether observed wage disparities are attributable to relatively lower female productivity, or instead disparities are due to gender wage discrimination. This approach is applied to tourism industry data gathered in the matched employer-employee data set Quadros de Pessoal (Employee Records). The main findings indicate that female employees in the tourism industry in northern Portugal are less productive than their male colleagues and that gender differences in wages are fully explained by gender differences in productivity.

Outbreak of vampire bat biting in a Venezuelan village

An outbreak of 154 cases of vampire bat biting in a four-month period in the gold mine of Payapal, a Venezuelan village, is reported. All patients were bitten during the night and the most bites were on their toes. No complication attributed to the bite was reported. Diagnoses of rabies virus made by means of immunofluorescence were negative. A possible reason for this outbreak may been the development of mining areas, with the inhabitants providing an alternative food source for the bats.

Burn wood influence on outdoor air quality in a small village: Foros de Arrão, Portugal

One Plus Sequential Air Sampler—Partisol was placed in a small village (Foros de Arrão) in central Portugal to collect PM10 (particles with an aerodynamic diameter below 10 μm), during the winter period for 3 months (December 2009–March 2010). Particles masses were gravimetrically determined and the filters were analyzed by instrumental neutron activation analysis to assess their chemical composition. The water-soluble ion compositions of the collected particles were determined by Ion-exchange Chromatography. Principal component analysis was applied to the data set of chemical elements and soluble ions to assess the main sources of the air pollutants. The use of both analytical techniques provided information about elemental solubility, such as for potassium, which was important to differentiate sources.
