    Full Text Available A common problem when trying to identify the sex of hatchling turtles is that juveniles are not obviously externally dimorphic and current techniques to identify sex are often invasive. In this paper, 300 eggs of Podocnemis expansa from Bananal Island, state of Tocantins (Brazil, were incubated at constant temperatures. The carapaces of the hatchlings were photographed and subjected to geometric morphometric analysis. The hatchlings were subsequently euthanized and had their gonads removed for sex determination. The pivotal temperature of P. expansa was 33.5ºC, confirming that this species has the highest pivotal temperature among reptiles. Geometric morphometric analysis of the shape of the carapace proved efficient in differentiating the sex of the hatchlings and confirmed that this methodology can be efficient for studies that need to ascertain the sex ratio in P. expansa hatchlings.

    Leptospirosis is a widespread zoonosis caused by bacteria of the genus Leptospira. Rodents appear to be the most important reservoirs of infection. They contaminate the environment and food and can transmit the pathogen when they are consumed by carnivores. Capybara ( Hydrochaeris hydrochaeris ) are efficient reservoirs of Leptospira, and because they are in close contact with farm animals and are found in semiurban areas, they represent a risk to public health. We isolated five Leptospira strains from capybara kidneys in Sao Paulo State, Brazil, in 2001 and typed them using serologic and molecular techniques. These strains include the Leptospira santarosai serogroup Grippotyphosa serovar Bananal. Pulsed field gel electrophoresis resulted in a unique pattern distinct from the reference strains, and the isolates clustered with greater than 85% similarity. The isolates also presented higher growth rates than other Leptospira serovars, with high minimal inhibitory concentration values for most of the tested antibiotics, with the exception of penicillin and ampicillin. This isolation and characterization of the L. santarosai serogroup Grippotyphosa serovar Bananal from capybara, highlights the importance of wild and sinantropic rodents as carriers of pathogenic leptospires.

    Full Text Available We conducted monthly snail captures in Bananal, State of São Paulo, Brazil, between March 1998 and February 2001, to identify Schistosoma mansoni vectors, estimate seasonal population changes, and delimit foci. We also evaluated the impact of improvements in city water supply and basic sanitation facilities. We identified 28,651 vector specimens, 28,438 as Biomphalaria tenagophila, 49 of them (0.2% infected with S. mansoni, and 213 as B. straminea, none of the latter infected. Vectors predominated in water bodies having some vegetation along their banks. Neither population density nor local vegetation could be linked to vector infection. We found the first infected snails in 1998 (from March to May. Further captures of infected snails ocurred, without exception, from July to December, when rainfall was least. Irrespective of season, overall temperature ranged from 16.5ºC to 21ºC; pH values, from 6.0 to 6.8. Neither factor was associated with snail population density. Frequent contact of people with the river result from wading across it, extracting sand from its bottom, fishing, washing animals, etc. Despite a marked reduction in contamination, cercaria shedding persists. Whatever the location along its urban course, contact with river Bananal, particularly of the unprotected skin, entails risks of infection.

  4. Relationships between water transparency and abundance of Cynodontidae species in the Bananal floodplain, Mato Grosso, Brazil

    Full Text Available The Cerrado in the Central Brazil is currently one of the most threatened ecosystems in the world. As a result, the aquatic habitats in this biome also undergo great impacts. Alterations related to land-use change increase sediment loadings in rivers, streams and lakes, resulting in sedimentation and decrease in water transparency. Water transparency determines underwater visibility conditions, and as a consequence fish assemblages respond to spatial and temporal changes in this variable. This work aimed to examine the influence of transparency on the abundance and distribution of Cynodontidae species, a visually oriented predatory fish group. Fish sampling was conducted in 15 sites located between Mortes and Araguaia rivers in the Bananal floodplain, Mato Grosso State. Regression analysis between relative abundance of Cynodontidae (in number of individuals and biomass and water transparency showed a positive and highly significant correlation, indicating that this group shows species-specific habitat affinities for clearer waters. These results suggest that the increase in water turbidity in this region can affect the patterns of abundance and distribution of the Cynodontidae species, as well as other visually oriented fishes.

Em consequência, os ambientes aquáticos desse bioma também sofrem grandes impactos. Alterações relacionadas a mudanças no uso da terra aumentam a descarga de sedimentos em rios, córregos e lagos, resultando em processos de assoreamento e diminuição da transparência da água. A transparência da água determina as condições de visibilidade subaquáticas, e em consequência os peixes respondem às variações espaciais e temporais desta variável. O objetivo deste trabalho foi verificar a influência da transparência da água na abundância e distribuição de peixes da família Cynodontidae, um grupo de peixes predadores que

    Full Text Available This article is about the eighteenth century mural paintings at the headquarters of Fazenda Rialto, in Bananal, which were destroyed in 1996. These constituted one of the most important sets of ambient paintings with secular themes produced in the state of São Paulo during the period corresponding to the first cycle of coffee production. Orally attributed to the painter José Maria Villaronga y Panella, all that remains of these paintings are some photographs and dozens of fragments, impossible to reassemble. Studying the fragments of the paintings of Rialto as primary material documents, the main objective of this article is to identify the artistic, technical, and executive characteristics of three sets of murals attributed to a single painter. A methodology which combines laboratory tests and historical research on artistic techniques was adopted for objectively recognizing the artistic and artisan characteristics of the period and discussing the attribution of exclusive authorship to the work. The analytical systems adopted for this purpose were: examination with ultraviolet and infra-red radiation, optical microscopy, Scanning Electron Microscopy (SEM and Energy Dispersive Spectrometry (EDS to analyze its chemical elements. Issues related to the limitations on official Brazilian preservation activities for this category of artistic work were also discussed, reflecting on the development and changes in notions of historicity related to the preservation of works from the past and their methodological implications for conservation and restoration.

    Full Text Available The coast of the state of Santa Catarina only has non-biogenic reefs, i.e. rocky and artificial reefs, and is considered the geographic south limit for many reef fish species. At present the diversity of organisms associated with reef environments is threatened. This study aimed to record the number of families and species of reef fish fauna of the north coast of the state of Santa Catarina. The data were collected through underwater visual census performed on Graças archipelago (26°12'S /48º29'W, Tamboretes archipelago (26°22'S/48°31'W and Barra do Sul islands (26°27'S/48º35'W. A total of 166 species was observed (6 elasmobranchii and 160 actinopterygii belonging to 66 families. The families with more species richness were Carangidae (16, Epinephelidae (9, Blenidae (8, Serranidae (7, Haemulidae (6, Sparidae (6 Tetraodontidae (6, Labridae-Scarini (5, Labrisomidae (5 Pomacentridae (5, Lutjanidae (5 and Muraenidae (5. This study add to the current published list, new 115 species, including new occurrences (e.g. Chromis limbata, and some endemic (e.g. Sparisoma amplum, exotic (e.g. Omobranchus punctatus, endangered (e.g. Hippocampus erectus and overexploited (e.g. Lutjanus analis species. Twenty one species are present in the IUCN’s list, twelve in the IBAMA’s list and four in the local list. All elasmobranchii recorded here are considered threatened species, like the brazilian guitarfish (Rhinobatos horkelii, which appears in three red lists, and it is considered critically endangered. All species of Epinephelidae are mentioned in the list of risk categories of the IUCN and five are cited as overexploited or threatened with overexploitation by IBAMA. Among Epinephelidae, the goliath grouper (Epinephelus itajara, is present in all red lists and has specific protection rules in Brazil. The gathered information will allow to take appropriate conservation measures, such as the establishment of marine protected areas, monitoring of fishing

    Full Text Available The Environmental Sensitivity Index Maps for Oil Spills (ESI Maps, or SAO in Portuguese constitute an essential component and source of basic information for emergency planning, response decision support and damage evaluation in case of oil spills. This study aims at the elaboration of sensitivity maps for oil spills for the islands within the Ubatuba municipality, north coast of the State of São Paulo. The adopted methodology is based on the Technical Specifications for the production of Environmental Sensitivity Maps for oil spills (SAO maps proposed by the Brazilian Ministry of Environment. The study involved the gathering of secondary data, followed by field work carried out in the summer and winter periods of 2007; the elaboration of the cartographic base maps and, finally, the integration of the data to a GIS (Geographic Information System. As a result it was registered and mapped the physical (geology, geomorphology, oceanography and climatology, biological (fauna, flora and coastal environments and socioeconomic (anthropic influence, human use, artificial structures and impacts resources of Ubatuba coastal islands. Eleven beaches have been identified, located at six islands, with distinct topographic and geomorphologic features. The beaches were classified with sensitivity index 4, because they are sheltered from actions of waves and currents. Most of the mapped environments (44.8% were classified with sensitivity index 8, indicating high sensitivity of the islands. The oil spill impacts on coastal environments can be significantly minimized during the contingency actions when previous knowledge of the ecosystems that compose the islands environment is available, especially when it is integrated into GIS data basis, capable of displaying easy-to-use maps. The environmental sensitivity mapping is an important management instrument, especially when dealing with sensible and poorly studied areas such as the islands of Ubatuba.

    Full Text Available Urban heat islands (UHIs in large cities and different climatic regions have been thoroughly studied; however, their effects are becoming a common concern in smaller cities as well. We assessed UHIs in three tropical cities, analyzing how synoptic conditions, urban morphology, and land cover affect the heat island magnitude. Data gathering involved mobile surveys across Paranavaí (Paraná, Rancharia (São Paulo, and Presidente Prudente (São Paulo, Brazil, during summer evenings (December 2013–January 2014. Temperature data collected over five days in each city point to heat islands with magnitudes up to 6 °C, under calm synoptic conditions, whereas summer average UHI magnitudes peak at 3.7 °C. In addition, UHI magnitudes were higher in areas with closely spaced buildings and few or no trees and building materials that are not appropriate for the region’s climate and thermal comfort.

    The northeastern coast of the State of Para and the Marajo Island - in Brazil, exhibit a wind potential that seems adequate to the generation of electric energy to supply local demands. These local demands are mostly formed by small towns and villages located invariably far from the big urban centers with little or no possibility to be supplied by the utility grid. In this paper it is intended to report the studies being conducted to design a hybrid wind diesel system to attend a small population center, namely the Algodoal Island, that is a representative sample of this region. It will be described the process of data acquisition and statistical treatment as well as some environmental, social and economic aspects regarding the Algodoal Island. Finally it will be presented a preliminary estimate of energy demand for this locality as well as a probable wind-diesel system arrangement to supply this demand.

    Full Text Available Two Leptospira sp. isolates were obtained by the first time from goats in Brazil and characterized by sequencing rrs, rpoB and secY genes, PFGE and typing with monoclonal antibodies. Both isolates are identical and belong to Leptospira santarosai. Analysis of the rrs and the rpoB genes sequences revealed 100% identity between the goat isolates and the Bananal reference strain. When secY sequences of the two isolates were compared to each other, it was observed that they had identical sequences. However, when compared to that of the Bananal reference strain, there were 15 mismatches along the 549 bp secY sequence. In conclusion, molecular methods are increasingly useful for the characterization of leptospires and allowed to identify those isolates of caprine origin as closely related but not identical to serovar Bananal, and constitute a new type named Carioca.

    Flavio do Nascimento Coelho

    Full Text Available In this study we analyze the population structure and diet of the coney Cephalopholis fulva at Trindade Island, Brazil, through direct observation with SCUBA diving in 11 reef sites around the Island, up to 50 m deep. Diet was based on 77 individuals collected with speargun. Mean population density and biomass were estimated at 29 individuals/100 m² and 13 kg/100 m², respectively. This species is regularly distributed along the costal environments of the Trindade Island, with no significant differences in densities and biomass detected among the different collection habitats (reef crest, reef slope, and reef plateau. However, significantly higher densities were observed micro-habitats with greater structural complexity, which may offer more shelter and food to C. fulva. Four food item groups were identified from the gut contents of C. fulva: Annelida, Crustacea, Teleostei, and Testudinata. It is the first record of predation of the green turtle Chelonia mydas hatchlings by the coney. Trindade Island seems to present the densest concentration of C. fulva in all Brazilian and Caribbean ecosystems inhabited by this species. Scarcity of competitors, predators, and fishing pressure may explain the high densities observed in the Island.

  17. Incidental catch of marine turtles by the artisanal fisheries on Santa Catarina Island, SC, Brazil

    2006-12-01

    Full Text Available The five species of sea turtles, which inhabit the Brazilian shore, have a wordwide distribution and are threatened with extinction. The south of Brazil is characterized as a feeding and breeding area of at least three of these species. The presence of turtles close to the shore and their incidental catch are occurrences reported by artisan fishermen of the Island of Santa Catarina in this work. The study was based on a questionnaire, applied to fishermen and fishfarmers at selected spots on the island. Scientific and popular names were matched using illustrations. The spots with the highest number of events and captures were close to the islands, rocky coasts and stony grounds, i.e. areas related with the foraging habits of the most abundant species, Chelonia mydas. The place, depth and size of the net are characteristics, which influence the capture. The time the net remains in the water is a factor which is fundamental to the survival of the captured turtles. The flesh of the turtle is used as an occasional feeding resource. Capacitation programs and training applied to the communities involved are recommended.

    The relative distribution of several compounds identified in four samples of recently deposited sediments of the Itacorubi Mangrove located on the Santa Catarina Island, southern Brazil, was compared with similar data on compounds extracted from fresh leaves of three mangrove species (Avicennia schaueriana, the dominant species in the area, Rhizophora mangle and Laguncularia racemosa) and the Gramineae Spartinna alterniflora. Terpenols, previously identified in mangrove species in northern Brazil, were also found. A. schaueriana mainly contains β-amyrin (90.6 μg g(-1) of extractable organic matter); low amounts of friedelin, betulin and germanicol were detected only in the leaf extract of this species. R. mangle also contained a significant amount of β-amyrin and it was the only species where taraxerol was detected. In contrast to the leaves, sediment extracts were dominated by germanicol, α-amyrin and campesterol. Despite its chemical lability, betulin was also detected. Two homologous series of α and ω-hydroxy fatty acids were detected in the acid-alkaline fraction. In spite of being reported in the literature as components of terrigenous plants, saturated ω-hydroxy acids were not identified. Our results indicate that although triterpenols may be used as biomarkers for mangrove-derived organic matter, their relative distribution can change according to the region.

    2004-08-01

    Full Text Available Acute cases of schistosomiasis have been found on the coastal area of Pernambuco, Brazil, due to environmental disturbances and disorderly occupation of the urban areas. This study identifies and spatially marks the main foci of the snail host species, Biomphalaria glabrata on Itamaracá Island. The chaotic occupation of the beach resorts has favoured the emergence of transmission foci, thus exposing residents and tourists to the risk of infection. A database covering five years of epidemiological investigation on snails infected by Schistosoma mansoni in the island was produced with information from the geographic positioning of the foci, number of snails collected, number of snails tested positive, and their infection rate. The spatial position of the foci were recorded through the Global Positioning System (GPS, and the geographical coordinates were imported by AutoCad. The software packages ArcView and Spring were used for data processing and spatial analysis. AutoCad 2000 was used to plot the pairs of coordinates obtained from GPS. Between 1998 and 2002 5009 snails, of which 12.2% were positive for S. mansoni, were collected in Forte Beach. A total of 27 foci and areas of environmental risk were identified and spatially analyzed allowing the identification of the areas exposed to varying degrees of risk.

  20. Natural regeneration in abandoned fields following intensive agricultural land use in an Atlantic Forest Island, Brazil

    2012-08-01

    Full Text Available The time required to regrowth a forest in degraded areas depends on how the forest is removed and on the type of land use following removal. Natural regeneration was studied in abandoned old fields after intensive agricultural land use in areas originally covered by Brazilian Atlantic Forests of the Anchieta Island, Brazil in order to understand how plant communities reassemble following human disturbances as well as to determine suitable strategies of forest restoration. The fields were classified into three vegetation types according to the dominant plant species in: 1 Miconia albicans (Sw. Triana (Melastomataceae fields, 2 Dicranopteris flexuosa (Schrader Underw. (Gleicheniaceae thickets, and 3 Gleichenella pectinata (Willd. Ching. (Gleicheniaceae thickets. Both composition and structure of natural regeneration were compared among the three dominant vegetation types by establishing randomly three plots of 1 x 3 m in five sites of the island. A gradient in composition and abundance of species in natural regeneration could be observed along vegetation types from Dicranopteris fern thickets to Miconia fields. The gradient did not accurately follow the pattern of spatial distribution of the three dominant vegetation types in the island regarding their proximity of the remnant forests. A complex association of biotic and abiotic factors seems to be affecting the seedling recruitment and establishment in the study plots. The lowest plant regeneration found in Dicranopteris and Gleichenella thickets suggests that the ferns inhibit the recruitment of woody and herbaceous species. Otherwise, we could not distinguish different patterns of tree regeneration among the three vegetation types. Our results showed that forest recovery following severe anthropogenic disturbances is not direct, predictable or even achievable on its own. Appropriated actions and methods such as fern removal, planting ground covers, and enrichment planting with tree species were

  1. Modelling the population control of the domestic cat: an example from an island in Brazil

    Directory of Open Access Journals (Sweden)

    ICM Lessa

    Full Text Available The domestic cat is an invasive species that often causes great impacts where introduced due to its high predatory and reproductive potential, especially on islands. In this study, carried out on Ilha Grande (RJ, Brazil, we aimed to: i estimate the population density of domestic cats, ii calculate the number of animals preyed upon annually by domestic cats, and iii evaluate the efficiency of methods to control the cat population. We used the Vortex program to project the population growth of domestic cats in fifty years, and simulated different scenarios of population control (without control, castration, spay and harvest. Population density of owned cats was 662 cats/km². The annual predation rate was 1.97 prey animals/cat which is an average of 1497.96 prey/year. The population would only be reduced if 70% of females were spayed or removed annually. Measures to control the domestic cat population must be undertaken urgently, since uncontrolled growth of this predator has the potential to seriously impact the biodiversity of Ilha Grande.

    Full Text Available Intraspecific karyotype variation in mammal species is very common and often caused by centromeric fusion of acrocentric chromosomes. We describe here a new karyotype 2n = 62 (FN = 112 for the genus Cavia from the Moleques do Sul Islands, of the southern coast of Brazil. We analyzed two male and four female karyotypes that had twenty-four biarmed pairs and six pairs of acrocentric chromosomes. The sexual pair consisted of a metacentric X-chromosome and a large acrocentric Y. C-bands were found in the centromeric and pericentromeric regions of almost all chromosomes, except for some small biarmed and acrocentric ones. Nucleolus organizer regions appeared in two biarmed chromosomes, and G-banding patterns were also seen.RESUMO A variação cariotípica nas espécies de mamíferos é bastante comum e geralmente causada pela fusão de cromossomos acrocêntricos. Foi descrito neste trabalho um novo cariótipo, com 2n = 62 e FN = 112, para o gênero Cavia proveniente das ilhas Moleques do Sul, da costa sul do Brasil. Foram analisados os cariótipos de dois machos e quatro fêmeas que possuiam 24 pares de cromossomos com dois braços e seis pares de acrocêntricos. O par sexual era constituído por um cromossomo X metacêntrico grande e um Y acrocêntrico. As bandas C estavam localizadas nas regiões centroméricas e pericentroméricas da maioria dos cromossomos, com exceção de alguns acrocêntricos e os cromossomos de dois braços menores. As regiões organizadoras de nucléolo ocorreram em dois cromossomos com dois braços e o padrão de bandamento G foi também apresentado.

    Full Text Available Waterbirds usually breed in an aggregate way, forming large breeding colonies with different species. This study describes biological aspects of waterbirds from a colony at Maracujá island, in the Babitonga bay estuary, north coast of Santa Catarina, Brazil. We collected data on species richness, abundance, breeding chronology, predation, and nest distribution in the island. Within the period from September 2010 to February 2011, 15 waterbird species were identified using the feeding and resting site, and, out of them, 5 species bred in the island (Nycticorax nycticorax, Nyctanassa violacea, Egretta caerulea, Phimosus infuscatus, and Aramides cajanea. We registered 154 active nests, 79 nests of N. Nycticorax, 14 nests of N. violacea, 6 nests of P. infuscatus, 5 nests of E. caerulea, and only 1 nest of A. cajanea. The estimated local population was 308 breeding individuals, and N. nycticorax was the most abundant species, accounting for 51% of nests. The months with higher concentration of nests were September, October, and November. In addition to waterbirds, 4 birds of prey and scavenger species were registered, which were responsible for egg and/or chick losses, along with Larus dominicanus. Maracujá island has been used for breeding by at least 5 species and its protection deserves attention, in order to ensure the maintenance and possibility to expand this breeding site.

R. mangle also contained a significant amount of β-amyrin and it was the only species where taraxerol was detected. In contrast to the leaves, sediment extracts were dominated by germanicol, α-amyrin and campesterol. Despite its chemical lability, betulin was also detected. Two homologous series of α and ω-hydroxy fatty acids were detected in the acid-alkaline fraction. In spite of being reported in the literature as components of terrigenous plants, saturated ω-hydroxy acids were not identified. Our results indicate that although triterpenols may be used as biomarkers for mangrove-derived organic matter, their relative distribution can change according to the region.A distribuição relativa de vários compostos identificados em quatro amostras de sedimentos recentemente depositados no manguezal do Itacorubi, localizado na Ilha de Santa Catarina, no sul do Brasil, foi comparada a dos diversos compostos extraídos de folhas frescas de três espécies de mangues: Avicennia schaueriana, espécie dominante na região, Rhizophora mangle, Laguncularia racemosa, e a gramínea Spartinna alterniflora.

    Full Text Available A small (100,000 m² rhodolith bank located at the Arvoredo Marine Biological Reserve (Santa Catarina, Brazil has been surveyed to determine the main bank components, the community structure, and carbonate production rates. Data from five photographic transects perpendicular to Arvoredo Island shore were complemented with sediment samples and shallow cores, all collected by scuba diving. The main bank component is the unattached, nongeniculate, coralline red algae Lithophyllum sp., used as substrate by the zoanthid Zoanthus sp. Percentage cover of living and dead coralline algae, zoanthids and sediment patches account for nearly 98% of the investigated area. Classification and ordination of samples showed that differences in the proportion of live and dead thalli of Lithophyllum sp. determine the relative abundances of zoanthids. Results also indicate that similarity of samples is high and community gradients are subtle. Significant differences in percentage cover along transects are concentrated in the central portion of the bank. Low carbonate content of sediments from deeper samples suggests low rates of recruitment and dispersal of coralline algae via fragmentation. However, carbonate production of Lithophyllum sp ranging from 55-136.3 g m-2 yr-1 agrees with production rates reported for other temperate settings. In the long run, rhodolith density at Arvoredo Is. is likely to be dependent upon random dispersal of spores and/or fragments from other source areas.Investigou-se um pequeno (100,000 m² banco de rodolitos localizado na Reserva Biológica Marinha do Arvoredo (Santa Catarina, Brasil para se determinar os pricipais componentes do banco, a estrutura da comunidade e a produção de carbonato de cálcio.

    Full Text Available The aim of this research was to reconstruct vegetation changes (with climate inferences that occurred during the Holocene in the Fernando de Noronha Island, Pernambuco State, northeastern Brazil. The research approach included the use of geochemical (mineralogy, elemental, carbon isotopes (δ13C, 14C and pollen analyses in soil organic matter (SOM and sediments collected in Lagoa da Viração and Manguezal do Sueste. The carbon isotopes data of SOM indicated that there was no significant vegetation changes during the last 7400 BP, suggesting that the climate was not the determinant factor for the vegetation dynamics. The pollen analysis of the sediment of a core collected in the Lagoa da Viração showed the absence of Quaternary material in the period between 720 BP and 90 BP. The mineralogical analysis of deeper layer showed the presence of diopside indicating this material was developed "in situ". Only in the shallow part of the core were found pollen of similar plant species of the modern vegetation. The geochemistry and isotope results, in association with the sediment type and pollen analyses of sediment samples of Manguezal do Sueste, indicated variations in the vegetation and in its location since the middle Holocene. Such variations can be associated with climatic events and sea level oscillations and also with anthropogenic events considering the last five hundred years.Esta pesquisa teve o objetivo de reconstruir trocas de vegetação (com referências climáticas que ocorreram durante o Holoceno na ilha de Fernando de Noronha, Estado de Pernambuco, nordeste do Brasil.

  9. The structure of rocky reef fish assemblages across a nearshore to coastal islands' gradient in Southeastern Brazil

    Fernando Zaniolo Gibran

    Full Text Available Local assemblages of fishes associated with reefs are influenced by interactions among the availability of larvae and survival of recruits with subsequent biotic and abiotic forcing, as well as by periodic and episodic disturbances of varying natures and magnitudes. Therefore, besides being structurally heterogeneous and patchily distributed, reef systems are strongly context-dependent due to the influence of a broad array of ecological processes. In order to assess interactions of local factors that influence the distribution and abundance of reef fishes within a coastal mosaic of rocky reefs, we tested the null hypothesis of no significant variation in fish assemblage structure, by comparing 33 sites along the northern coast of the São Paulo State, Southeastern Brazil. Replicated stationary visual census samples (n = 396 were obtained at different distances from the coast, depths and wave exposures, including the mainland, three relatively small coastal islands, and the two margins of a wide channel between the mainland and the large São Sebastião Island (~350 km², totaling 225 h of SCUBA diving. The regional rocky shore fish fauna comprised 106 species (41 families, with preponderance of diurnal mobile-invertebrate feeders. Samples from the outer margin of the São Sebastião Island, together with those from Alcatrazes, Búzios, and Vitória islands were significantly dissimilar from samples from the coastal sites at the São Sebastião Channel. Species richness tended to increase in a gradient from the coast to the more offshore islands. Local conditions such as depth and other habitat characteristics also influenced fish assemblages' structure. Distance from coast and depth were the main predictors for fish assemblages, followed by water transparency, temperature and benthic cover. This study represents the first regional-scale assessment of fish assemblages associated with rocky reefs in the São Paulo State coast, filling a major

    Full Text Available The Environmental Sensitivity Index Maps for Oil Spills (ESI Maps, or SAO inPortuguese constitute an essential component and source of basic information for emergency planning, response decision support and damage evaluation in case of oil spills. This studyaims at the elaboration of sensitivity maps for oil spills for the islands within the Ubatubamunicipality, north coast of the State of São Paulo. The adopted methodology is based on theTechnical Specifications for the production of Environmental Sensitivity Maps for oil spills(SAO maps proposed by the Brazilian Ministry of Environment. The study involved thegathering of secondary data, followed by field work carried out in the summer and winterperiods of 2007; the elaboration of the cartographic base maps and, finally, the integration ofthe data to a GIS (Geographic Information System. As a result it was registered and mappedthe physical (geology, geomorphology, oceanography and climatology, biological (fauna,flora and coastal environments and socioeconomic (anthropic influence, human use, artificialstructures and impacts resources of Ubatuba coastal islands. Eleven beaches have beenidentified, located at six islands, with distinct topographic and geomorphologic features. Thebeaches were classified with sensitivity index 4, because they are sheltered from actions ofwaves and currents. Most of the mapped environments (44.8% were classified withsensitivity index 8, indicating high sensitivity of the islands. The oil spill impacts on coastalenvironments can be significantly minimized during the contingency actions when previousknowledge of the ecosystems that compose the islands environment is available, especiallywhen it is integrated into GIS data basis, capable of displaying easy-to-use maps. Theenvironmental sensitivity mapping is an important management instrument, especially whendealing with sensible and poorly studied areas such as the islands of Ubatuba.

    This study analyzed the microbial diversity colonizing the surface of an oil sample during its contact with water, off the Trindade Island coast and simulated the efficiency of eight different bioremediation strategies for this environment. The diversity analysis was performed using acrylic coupons that served as the support for an oil inclusion at sea. The coupons were sampled over 30 days, and T-RFLP multiplex was employed to access the diversity of fungi, Bacteria and Archaea present on the oil surface. The bioremediation strategies were simulated in a respirometer. The results showed that the bacterial domain was the most dominant in oil colonization and that the richness of the species attached to the oil gradually increases with the exposure time of the coupons. The combination of biostimulation and bioaugmentation with a native population was proven to be an effective strategy for the remediation of oil off the Trindade Island shoreline.

    Full Text Available The Metropolitan Area of São Paulo (MASP is one of the most populated regions of the planet with one of the largest impervious regions as well. This research work aims to characterize MASP heat island (HI effect and its interaction with the local sea breeze (SB inflow in rainfall amounts and deep convection. The combined SB-HI produces direct circulation over the MASP and produces severe weather and socioeconomic impacts. All SB-HI episodes between 2005 and 2008 are identified and analyzed with surface and upper air measurements, weather radar, and satellite data. The current work indicates that intense SB-HI episodes are related to air and dew point temperatures above 30°C and 20°C, respectively, right after the passage of the SB front over MASP. Results indicate that the precipitation related to SB-HI episodes is up to 600 mm or about four times higher than that in rural or less urbanized areas in its surroundings. Measurements indicate that 74% of SB-HI episodes are related to NW winds in earlier afternoon hours. Moving cold fronts in southern Brazil tend to intensify the SB-HI circulation in MASP. A conceptual model of these patterns is presented in this paper.

    In this paper a Coastal Dune Vulnerability Index (CDVI) has been applied on a beach located in the eastern side of Sao Francisco do Sul Island (Brazil). The aim of this study is to assess the vulnerability of a coastal dune system and to identify the areas that result most sensitive to environmental changes. The CDVI has been applied along six transects traced out on two sectors that have been selected based on dune characteristics: Zone A is characterized by well developed parabolic dunes, whereas Zone B is characterized by transverse dunes. The analysis involved 51 quantitative and qualitative variables, divided into five groups: geomorphological dune system condition, marine influence, Aeolian effect, vegetation condition and human effect. The total CDVI was computed as the unweighted average of the partial vulnerability indices. In summary, the total vulnerability can be classified as medium: the geomorphological factor must be monitored at Grande beach, in particular the blowouts in Zone A and the frontal dune retreat in Zone B. The results of the study confirm that the management of coastal areas might be improved using a tool such as the CDVI, which can be easily applied on a regular basis to take under control the factors that mostly affect the evolution of the site.

    This work was carried out in the Enseada da Baleia and Vila Rápida communities. Data was provided by the Co-Management Committee of the Cardoso Island State Park (PEIC) on manjuba fishery management, technique and strategies used by the fishermen, as well as locally accumulated knowledge. Based on the results, social, ecological, and economic aspects of this type of fishing were analyzed. The importance of the accumulated knowledge and experience of this community, as well as the limitations imposed by local fishing gear, was concluded to be essential in conserving manjuba fishery conditions in the area. Industrial fishing, relevant state legislation, and market conditions were found to be the main obstacles to local fishery. Various proposals are suggested for manjuba fishery management, with emphasis on the need for fishing community participation in whatever measures are ultimately implemented.

    Full Text Available Sterna hirundinacea (Lesson, 1831 is a migratory seabird that breeds in the Pacific Coast (from Peru to Chile and along the Atlantic coast of South America from Espírito Santo (Brazil to Terra del Fuego (Argentina. This paper describes the reproductive success of South American Terns on Cardos Island, Florianopolis, Brazil in the breeding seasons of 2003, 2005 and 2006. The colony was formed in mid-May in 2003 and early April in other years, with the total number of nests ranging from 1,852 in 2006 to 2,486 in 2005. Hatching success was estimated at 76.39% in 2006, 62.73% in 2003 and 41.1% in 2005, the lowest value that could be attributed to predation by hawks Caracara plancus, lizards Tupinambis merianae and black vulture Coragyps atratus. The chicks hatched in July in 2003, and in June 2005 and 2006, and fledging success was 50.94%, 35.96 and 53.47% respectively. Cardos Island has been constantly used as a breeding site by South American Terns, and therefore represents an important area for conservation of this species. This success could be attributed to low pressure of Kelp gulls (Larus dominicanus, the main predator of seabirds along the Brazilian coast.Sterna hirundinacea (Lesson, 1831 é uma ave migratória que nidifica na costa do Pacífico (do Peru ao Chile e ao longo do Atlântico Sul do Espírito Santo (Brasil até a Terra do Fogo (Argentina.

    Full Text Available Bothrops insularis is a threatened snake endemic to Queimada Grande Island, southern coast of São Paulo, Brazil, and the occurrence of sexual abnormalities in females (females with functional ovaries and rudimentary hemipenis has been reported in this population. To date there are few data regarding developmental features of this particular species. The aim of this study was to follow some developmental features in specimens maintained in captivity for seven years in the Herpetology Laboratory at Instituto Butantan, São Paulo, Brazil. We verified a pronounced sexual dimorphism in development and venom production in the specimens analyzed. In this regard, females showed greater length, mass and amount of venom in comparison to males. Our results suggest a possible niche partitioning between the sexes that reduces (or minimizes intraspecific disharmonic interactions (eg. competition on their small living area (Queimada Grande Island. Taken together, our data suggest that males and females probably are divergent in their diets, with females feeding preferentially on endothermic prey (such as migratory birds, while males maintain the juvenile diet (with the major items being ectothermic prey.

    PD. Ferreira Júnior

    Full Text Available Nest site has influence on incubation duration and hatching success of two Neotropical turtles, the Giant Amazon River Turtle (Podocnemis expansa and Yellow-Spotted Side-Neck Turtle (Podocnemis unifilis - "Tracajá". The 2000 and 2001 nesting seasons have been monitored at the Javaés River in Bananal Island, Brazil. Although they nest on the same beaches, there is a separation of the nesting areas of P unifilis and P. expansa nests on the upper parts of the beach. The incubation duration for P. expansa is influenced by the nesting period, the height of the nest from the river, the clutch size, and the grain size in the site of the nest. Nests of Podocnemis expansa placed in coarse sediments have shorter incubation duration than those placed in finer sediments. The hatching success in P. expansa is influenced by grain size, incubation duration, and nesting period. The grain size is negatively correlated with hatching success, indicating that the nests situated in finer-grained sand have better chances of successful egg hatching than those in coarser-grained sand. Nests of the end of the reproductive season have lower hatching success and incubation duration than those at the start of the season. For P. unifilis, the nesting period and nest depth influence the incubation duration; moreover, the river dynamics significantly affect the hatching success. The oscillation of the river level and the moment of initial increase, the height of the nest from the river level, and the nesting period are all decisive components for hatching success. The results of this research show the importance of protecting areas with great geological diversity, wherein the features of the environment can affect the microenvironment of nests, with consequences on incubation duration and hatching success.

    A 3,000 m2 area of seasonally inundated forest on the island of Ilha do Mel (25 degrees 30" S 48 degrees 23" W) in Paraná, Brazil, was sampled by collecting plants from all strata, using climbing equipment when necessary. The area harbors 103 species of epiphytes, in 49 genera and 20 families, of which 28 species are pteridophytes and 75 magnoliophytes (64 Liliopsida, 11 Magnoliopsida). The most common families are Orchidaceae, Bromeliaceae, Polypodiaceae and Araceae, and frequent genera are Vriesea, Epidendrum, Maxillaria, Pleurothallis and Prosthechea. Eight families were represented by one species each. Most species were classified as obligatory holoepiphytes (62 %), followed by the relatively more rare preferential holoepiphytes (13 %), facultative epiphytes (11 %), hemiepiphytes (9 %) and accidental epiphytes (6 %).

    Full Text Available The states that make up the Legal Amazon Region, which include the state of Maranhão, account for 99% of registered cases of human malaria in Brazil. It is also believed that transmission of malaria from nonhuman primates (NHP to humans occurs in this region, because of current reports of seroepidemiological results from samples from humans and NHP coexisting in the same areas. This study aimed to make morphological, serological and molecular diagnoses of Plasmodium spp. in neotropical primates on the island of São Luís, state of Maranhão, Brazil. The diagnostic techniques used were optical microscopy, the polymerase chain reaction (PCR and the indirect immunofluorescence assay (IFA. From June 2009 to April 2010, 70 NHP were sampled: 50 at the Wild Animal Screening Center (CETAS, located in the municipality of São Luís and 20 free-living individuals that were caught in a private reserve located in the municipality of São Jose de Ribamar, state of Maranhão. Under an optical microscope, 140 slides (two from each animal were evaluated and five animals (7.1% were found to be positive. IFA did not detect anti-Plasmodium spp. From PCR on the 70 animals sampled, amplified Plasmodium spp. products were observed in 13 samples, of which eight (61.5% were from free-living animals and five (38.5% were from animals at CETAS.

    Full Text Available In 2012 a malacological survey of the breeding sites of Biomphalaria glabrata and B. straminea, the two intermediate host snails of Schistosoma mansoni, was carried out on Itamaraca Island in Pernambuco, Brazil. This study has now been extended by studying the competition between the two species. Snails were collected and dissected to identify the species and tests were performed to verify S. mansoni infection. Student’s t test was used to compare the proportion between the two species and their breeding sites and a parasitological survey was conducted among local residents, using the Kato-Katz method. The spatial distribution of the two snail species was determined using TerraView, while a snail density map was constructed by Kernel estimate. The survey identified two breeding sites for B. glabrata with 17 specimens and 19 breeding sites for B. straminea with 459 snails, all of them negative for S. mansoni infection. The statistical analysis revealed that the proportion of the numbers of specimens and breeding sites of B. straminea (37.84 ± 9.01 were significantly greater than those of B. glabrata (8.50 ± 6.50. Parasitological examinations from 41 residents diagnosed two cases of schistosomiasis with parasite loads of 60 and 84 eggs per 1 g of stool, respectively. This indiction of a competitive process between the two snail species requires monitoring of schistosomiasis in the resident and travelling human populations occupying this environment, which could potentially result in social and economic changes on the island risking its attraction as a centre for eco-tourism.

    In the present study, acrylic coupons with a thin layer of oil on the surface were incubated in the coastal water of Trindade Island, Brazil, for 60 days. The microorganisms adhered to the coupons were isolated using enrichment medium with hexadecane and naphthalene as the sole carbon and energy source. A total of 15 bacterial isolates were obtained, and the ability of these isolates to use different hydrocarbons as the source of carbon and energy was investigated. None of the isolates produced biosurfactants under our experimental conditions. Subsequently, identification methods such as partial sequencing of the 16S rRNA gene and analysis of fatty acids (MIDI) profile were employed. Among the 15 isolates, representatives of Actinobacteria, Firmicutes, and Alphaproteobacteria were detected. The isolates Rhodococcus rhodochrous TRN7 and Nocardia farcinica TRH1 were able to use all the hydrocarbons added to the culture medium (toluene, octane, xylene, naphthalene, phenanthrene, pyrene, hexadecane, anthracene, eicosane, tetracosane, triacontane, and pentacontane). Polymerase chain reaction amplification of the DNA isolated by employing primers for catechol 2,3-dioxygenase, alkane dehydrogenase and the alpha subunit of hydroxylating dioxygenases polycyclic aromatic hydrocarbon rings genes demonstrated that various isolates capable of utilizing hydrocarbons do not exhibit genes of known routes of catabolism, suggesting the existence of unknown catabolic pathways in these microorganisms. Our findings suggest that the microbiota associated to the coast of tropical oceanic islands has the ability to assist in environmental regeneration in cases of accidents involving oil spills in its shore. Thus, it motivates studies to map bioremediation strategies using the autochthonous microbiota from these environments.

  10. An integrative approach-using field and laboratory data to characterize shell utilization and selection pattern by the hermit crab Pagurus criniticornis (Paguridae from Anchieta Island, Brazil

    Full Text Available Abstract The aim of this study was to characterize the pattern of gastropod shell occupation in the field and selection of shell size and type under laboratory conditions by the hermit crab Pagurus criniticornis (Dana, 1852, inhabiting the infralittoral area of Anchieta Island, São Paulo, Brazil. Hermit crabs were obtained monthly during 1999 by SCUBA diving. For experiments under laboratory conditions, samplings were performed in 2002. The hermit crabs occupied 16 species of gastropods shells. Cerithium atratum (Born, 1778 was the most occupied shell (89.31%, followed by Morula nodulosa (4.73% (Adams, 1845. No difference was observed in the pattern of occupation between males and females. The equations that best demonstrated the relationship between hermit crabs and their shells were those that involved Shell Wet Weight (SWW and Shell Internal Volume (SIV. The laboratory experiments were in accordance to the pattern of occupation observed in the field; the mean value of SAI (Shell Adequacy Index recorded to the population studied was 1.13 with a trend to increase this value in the last size classes. The results obtained corroborate with the hypothesis of the occupation process of shells governed not only by availability of shells, but also by its architecture. In addition, the shell stock in the area is one another important condition related to the exhibited pattern of shell occupation by P. criniticornis, and allows the stable coexistence among the island assemblage. The pattern of occupation observed promotes a high reproductive profile for the population studied, maximizing the populational growth.

    Multiple stress mechanisms have caused a worldwide decrease in seagrasses, which are vulnerable to environmental and/or anthropogenic pressure. The loss of seagrass meadows of Halodule wrightii is reported for the littoral of Itamaracá Island (Northeastern Brazil). The present study identified the main anthropogenic factors that negatively influenced over the abundance and distribution of seagrass meadows between July and September 2007 at the Jaguaribe and Pilar Beaches, Eastern littoral of Itamaracá. Anthropogenic impact included the discharge of untreated sewage through fluvial channels, urban and commercial development along the coast, the anchoring of motorized and non-motorized boats, diverse fishing techniques and the dumping of solid waste. The data indicates that the Pilar is an environment with a higher impact index (71.43%) when compared with the Jaguaribe (57.14%), standing out the number of boats with a central motor, the total number of boats, the presence of shellfish gatherers and coastal urban development. The present study reinforces the need for defining management and conservation measures for this ecosystem, which has high ecological and economic value.

    The main goal of this investigation was to characterize the population structure and shell occupancy of two sympatric hermit-crab species, Pagurus brevidactylus and Paguristes tortugae. The study was undertaken at Couves Island on the southeastern coast of Brazil, from March 2010 through February 2011, on subtidal rocky bottoms. Specimens were collected by SCUBA diving sessions. A total of 195 individuals of P. brevidactylus and 132 of P. tortugae were examined. Both populations showed unimodal size-frequency distributions, which were non-normal for P. brevidactylus and normal for P. tortugae. The median size of P. brevidactylus was significantly smaller than P. tortugae; in both species, males were significantly larger than females. For both, juveniles and ovigerous females were recorded in all size classes and in almost the entire sampling period. No significant departures from the 1:1 sex ratio were detected, although some size classes were skewed. Overlaps in shell occupation were recorded. Pagurus brevidactylus and P. tortugae showed similar population features; they reached sexual maturity at small sizes, and the nearly year-round presence of young and ovigerous females suggests continuous reproduction. These inter-specific interactions involving resource partitioning suggest a regulatory process that is probably part of the equilibrium strategy of these populations.

    Full Text Available The dynamics of alluvial deposits in floodplains forms islands and sandbanks. Deposits frequently accumulate at the river margins and on islands with consequent side growths. One of these sandbanks which started to form in 1952 annexed an area of 12.4ha to the Porto Rico island (53º15’W and 22º45’S. At present a forest fragment of approximately 2.0 ha exists in this place. The structural analysis of arboreous vegetation of this fragment showed a floristic gradient related to the physical and chemical variations of the substratum. High density of pioneer species associated to the absence of recruitment of new individuals of these and other successional categories indicated that the forest was impaired in its succession process. This fact could be associated with constant disturbances caused by cattle in the area.A dinâmica de deposições aluviais em planícies de inundação proporciona a formação de ilhas e barras (bancos de areia, que muitas vezes agregam-se às margens dos rios ou ilhas propiciando o seu crescimento lateral. Uma dessas barras, com início de formação a partir de 1952, agregou a ilha Porto Rico (53º15’W e 22º45’S uma área de 12,40ha, onde existe, atualmente, um fragmento florestal de aproximadamente 2,0ha. A análise estrutural da vegetação arbórea desse fragmento mostra a presença de um gradiente florístico relacionado às variações físicas e químicas do substrato. A elevada densidade de espécies pioneiras, associada a ausência de recrutamento de novos indivíduos, dessas e de outras categorias sucessionais, indicam que esta floresta está limitada em seu processo de sucessão, podendo, este fato, estar associado às constantes perturbações provocada pela presença de gado na área.

    Full Text Available This research was carried out to evaluate the influence of seasonal variation in physicochemical composition and microbiological profile of buffalo milk and of the artisanal cream and butter types cheeses produced on Marajó Island. Eighteen farms located of the island were involved in the study. Milk and cheese quality were evaluated in two typical seasons. The rainy, from January to June and dry, from July to December. Samples were submitted to a detailed set of laboratorial analyses. Physicochemical composition of buffalo milk was influenced by the seasons. Compared to rainy, the dry period showed an increase in fat (5.53±0.71 to 6.74±1.19 and lactose (4.77±0.20 to 5.20±0.20 concentrations and reduction in total solids (16.89±0.92 to 15.77±1.54, nonfat dry matter (9.94±0.36 to 8.99±1.23 and minerals (0.84±0.12 to 0.62±0.09 concentrations (p<0.05. The season influence was observed in physicochemical composition of both cheese-types. Compared to rainy season, in the cream cheese type, higher values (p<0.05 were found for titratable acidity (0.63±0.02 to 0.78±0.15, fat (32.38±3.22 to 36.89±4.59, fat in the dry matter (55.06±3.26 to 63.92±2.49 but lower values for water activity (0.99±0.02 to 0.49±0.03, minerals (2.37±0.55 to 1.40±0.02 and calcium (0.28±0.08 to 0.18±0.07. For the butter cheese type, in the dry season, higher values were found only for titratable acidity (0.49±0.02 to 0.38±0.0 and lower values for water activity (0.18±0.07 to 0.45±0.08. The study have shown that some components of the buffalo milk and artisanal cheeses produced on Marajó Island are influenced by the dry and rainy typical seasons and therefore, some sensory variations are expected around the year.

    Full Text Available Holocene beachrocks of the Jaguaribe beach, State of Pernambuco, northeastern Brazil, consist of horizontal, cemented layers approximately 40 cm thick. The cement shows three textural varieties: (a calciferous, surrounding siliciclastic grains, (b micritic, with an acicular fringe; and (c cryptocrystalline calcite in pores. Early cementation took place at the water table below beach ridges, where geochemical, hydrodynamic and, perhaps, also microbiological conditions favored rapid precipitation of aragonite and/or high-Mg calcite. delta13C values range from -1.8 to +1.5? for dissolved carbonate in interstitial water and from +0.2 to +2.1? for bioclastic components. delta18O values range from -2.8 to +0.5? for seawater, freshwater and interstitial water. delta13C values and diagenetic features suggest that cementation occurred in meteoric-vadose and/or marine-phreatic water by loss of CO2 during evaporation of the interstitial water. Locally, superimposed low-Mg calcite cements point to subsequent freshwater influence. Total-rock cement composition of vertically stacked beachrock beds at the Jaguaribe beach shows that the highest beachrock bed is older than the one (of same petrographic composition situated at the current groundwater level. This implies a downward progression of cementation, which probably followed the sea-level fall after a local high stand.

    Insect seed predation may vary depending on seed production. The present study considers the hypothesis that the rates of seed predation tend to be smaller in years of higher fruit production. Thus, we monitored the production of fruits and predation of seeds of the palm Syagrus romanzoffiana over 2 years in the Atlantic Forest (Parque Municipal da Lagoa do Peri, Florianópolis, SC, Brazil), between July 2006 and June 2008. Plots of 0.25 m(2) were fitted under 20 mother plants and fruits were monthly collected for assessment of abundance and seed predation. There was variation in fruit production between the 2 years and among reproductive plants. Predation rates were high and occurred in the predispersal phase by the Curculionidae Revena rubiginosa Boheman, Anchylorhynchus aegrotus Fahraeus, and Anchylorhynchus variabilis Gyllenhal. Seed predation by these species of Anchylorhynchus is first registered in the present study. In average, about 60% of the seeds monthly produced in the population tend to escape insect predation in year of high or low production, becoming available for recruitment. The predation rate was not related to the amount of fruits produced per reproductive plant. Also, different than expected, there was a positive relation between the rates of seed predation and the total of fruits produced monthly on the plots. Thus, no evidence for the satiation of insect seed predators was found in this study with S. romanzoffiana.

    Immature phlebotomine sand flies develop in soils with essential and ideal characteristics for their life cycle, such as organic matter, humidity, temperature and low levels of light. Information regarding the potential breeding places of these dipterans is fundamental to understand the epidemiology and ecology of leishmaniasis, in addition to its importance to control them. In the present study, we aimed to find natural breeding sites of sand flies on Marambaia Island with the aid of emergence traps and direct search of immature forms using the flotation technique with saturated sugar solution in organic substrates of the region. Both methods were effective, with a total of 42 specimens of six different species - including some species that participate in the transmission cycle of American Tegumentary Leishmaniasis - collected by the emergence traps, and five immature forms obtained by floatation technique. However, further studies are still necessary, mainly with respect to the ecology and biology of immature sandfly stages, so that control measures focused on breeding sites can produce positive sustainable results in natural environments.

    The occurrence of human pulmonary dirofilariasis maintains a relation with the prevalence of Dirofilaria immitis infection in the canine population. Several mosquito species are vectors of this nematode. Canine blood samples collected in Pingo d'Agua and União villages, Salvaterra municipality (Marajó Island, Pará), in June, 2004 (n = 34) and April, 2005 (N = 90) were analyzed. Parasitological and immunological (ELISA--kit SNAP(R) 3DX Biobrasil) diagnoses were compared following the examination of 34 samples. The prevalence in the population (N = 90) was evaluated by means of ELISA. ELISA revealed more positive samples (25/34; 73.5%) than thick smears (23/34, 67.6%) or Knott (21/34, 61.8%), but the differences were not significant (p > 0.05). The frequency of D. immitis infection was 58% in dogs ranging from 0-2 years old, whereas in older dogs it was 100%. The prevalence of canine dirofilariasis was high in Pingo d'Agua and Vila União (53.5%), indicating the risk of parasite transmission to the people in this area.

    Full Text Available The caridean freshwater shrimp Atya scabra is a common resident of stream systems of tropical rainforests in America, including Brazilian drainages. This shrimp has an amphidromous life cycle, which increases its vulnerability when facing habitat fragmentation. Since information on the reproduction of this species is still limited, we present here data on egg production, egg loss, and energy investment, to achieve a better understanding of reproductive features of A. scabra. Specimens were collected between 2006 and 2007 in São Sebastião Island, southeastern Brazil, in 13 locations. The fecundity of 21 ovigerous females analyzed ranged between 414 and 19,250 eggs, which were higher than previously reported. However, the larger size of females analyzed may explain the observed intraspecific difference in egg production. During embryogenesis, egg volume and water content increased by 103 and 22.6%, respectively. The initial egg volume of A. scabra in the present study (0.027 mm³ was slightly lower, but comparable to the values reported previously from the same study area. During incubation, females of A. scabra lost 15% of their initially produced eggs. The reproductive output (average RO of 3.6% is the first report for any atyid species. Its value is fairly low compared to other freshwater shrimps, and it is hypothesized that this might be related to a high energy investment in morphological adaptations, which allows the shrimp to cling on to the substrate in the fast flowing environment they inhabit. Additionally, the long life span, a well-known phenomenon in atyid shrimp, may allow the species to invest a relatively low amount of energy per brood in egg production, but over a longer time span.

    Isotopic determinations for O and C were performed in coral skeletons collected in beach rocks from two localities (Orange and Catuama), Itamaraca Island, north littoral of the State of pernambuco, northeastern Brazil. Large variations of {delta}{sup 18} O and {delta}{sup 13} C in corals from both localities are found, the largest ones being observed at the Orange locality {delta}{sup 13} C in this locality varies from -0.8 to +1.8% PDB and {delta}{sup 1.8} O from -5.3 to -1.8% PDB, while at the Catuama locality, they vary from -1.8 to 0.1% PDB and -3.8 to -2.7% PDB, respectively. Large variations in {delta}{sup 18} O (up to 2.5%) coupled with weakly defined positive correlation between {delta}{sup 18} O and {delta}{sup 13} C, can be attributed to temperature variations as consequence of climatic perturbations. Temperature estimates, calculated from {delta}{sup 18} O values, assuming isotopic equilibrium with seawater, yield values between 24.9 deg C and 43.1 deg C at Orange, and from 28.4 deg C to 35 deg C at Catuama, all of them (expect one growth band from one sample) are high enough for the full development of the coral colony. Temperature average is 31.4 deg C at Orange, which is a little bit higher than that at Catuama, but both of them indicate thermal stress conditions. In all analyzed specimens, expect for one, at Orange, T increases was accompanied by decreasing in the organic activity, as suggested by corresponding negative {delta}{sup 13} C anomaly. Therefore, the observed bleaching is possibly related to thermal stress and the high T may be related to the El Nino-Southern Oscillation (ENSO) warning event. On the other hand, anthropogenic action at Orange, local of intense tourism throughout the year, coupled with high rate of sedimentation in the region, may contribute to the observed coral bleaching.

    The present study deals with shrimps of the family Alpheidae collected in the shallow waters around the remote Trindade & Martin Vaz Archipelago, situated 1200 km off the coast of Espírito Santo, Brazil. A few additional samples came from dredges on top of the seamounts of the Vitória-Trindade Seamount Chain. A total of 23 species in eight genera are reported, the vast majority representing new records for the area. One species is described as new, Synalpheus trinitatis sp. nov., based on the type material from Trindade Island. The new species clearly belongs to the Synalpheus brooksi Coutière, 1909 species complex, differing from all its other members by at least two morphological features. Four species represent new records for Brazil and the southwestern Atlantic: Alpheopsis aequalis Coutière, 1897 sensu lato, Alpheopsis chalciope de Man, 1910 sensu lato, Alpheus crockeri (Armstrong, 1941) and Prionalpheus gomezi Martínez-Iglesias & Carvacho, 1991; the two species of Alpheopsis are recorded from the Atlantic Ocean for the first time. The colour pattern of the recently described Alpheus rudolphi Almeida & Anker, 2011, a species endemic to Brazil, is shown for the first time and compared to the colour patterns of the four closely related species of the A. armatus Rathbun, 1901 complex from the Caribbean-Florida region. A brief zoogeographical analysis of the alpheid fauna of the oceanic islands of the tropical southern Atlantic (Trindade & Martin Vaz, Fernando de Noronha, Atol das Rocas, São Pedro & São Paulo, Ascension, Saint Helena, Cape Verde, São Tomé & Príncipe) is also provided.

    Full Text Available Studies suggest that the Marajó Island has experienced neotectonic activity during its latest evolution. However, there are no data demonstrating the presence of tectonic structures in its shallow subsurface. This work integrates vertical electric sounding, morphostructural lineaments, and geological data aiming to show fault control on the Late Pleistocene-Holocene sedimentation of this area. Resistivity values were related to mud ( 500 Ωm. The latest values were related to the unconformity with lateritic paleosol at the top of the Barreiras Formation. Despite the values ≤ 500 Ωm of both the Barreiras Formation and the Late Pleistocene-Holocene unit, the latter was distinguished along four electric sections due to the presence of this unconformity, combined with the integration of available 14C, and luminescence ages of Quaternary sediments. The electric sections recorded several places with lateral interruptions of resistivity values within short distances, which were related to faults. The Miocene strata were vertically displaced by normal faults, giving rise to new accommodation space where Late Pleistocene-Holocene sediments were deposited. Fault reactivation was crucial to renew sedimentation in eastern Marajó Island during its latest evolutionary stage.

    Full Text Available Seabirds play a significant role as bioindicators: they are conspicuous, relatively easy to observe, well-established studied group of organisms, and in the focus of public interest due to pollution in aquatic ecosystem. Systematically, a significant number of man-made chemicals have been introduced in the marine environment and represent the major problem arising in the development worldwide. Many of these chemical contaminants are persistent, known to bioaccumulate and biomagnify through the aquatic food web, affecting species associated with aquatic systems. Dioxins [polychlorinated dibenzo-p-dioxins (PCDD, dibenzofurans (PCDF] and polychlorinated biphenyls (PCB concentrations were measured in Kelp gull Larus dominicanus collected from 2006 to 2011 on Marambaia Island, Sepetiba Bay, Rio de Janeiro State, Brazil. Detectable liver concentrations of PCDD Fs-1 and PCBs were found in all samples analyzed. These represent some of the first measurements of PCDD Fs-1 and PCBs in seabirds from this area. Although levels of these contaminants in the tested species currently appear to fall below critical values, a continuous and systematic monitoring on these compounds becomes essential and desirable to not express toxic values in the future.

    Full Text Available INTRODUCTION: Visceral leishmaniasis is a serious public health problem that requires global control strategies, especially with respect to factors that may intervene in reducing the incidence of endemicity. In this work, rainfall density and temperature were correlated with the incidence of human cases in an area endemic for leishmaniasis in São Luis do Maranhão, Northeastern Brazil. METHODS: Notification of human cases by the National Health Foundation/Regional Coordination of Maranhão (FUNASA/COREMA from 2002 to 2010 was used. Ecological data (mean temperature and rainfall density were provided by the Meteorological Office of State. RESULTS: A significant association was verified between the number of VL cases and rainfall rate but not in the analysis concerning mean temperatures. CONCLUSIONS: These data suggest that the control actions in visceral leishmaniasis should be performed during rainy season in the State of Maranhão, which is in the first half of the year.

    This article presents the hourly and seasonal distribution of the Lutzomyia longipalpis sand fly captured on São Luís Island, Maranhão State. A total of 11,200 specimens were captured during monthly use of CDC light traps indoors and in animal sheds, between 6:00 PM and 6:00 AM, in 1996 and 1997. The sand fly behaved as an annual species, with a high frequency year-round, while it was most abundant during the rainy season (57.2%) as compared to the dry season (42.8%). The highest frequencies during the rainy season occurred in January and April and in the dry season in July and November. The species was found all night long, mainly between 6:00 PM and 10:00 PM in animal sheds and between 8:00 PM and 2:00 AM indoors.

  14. Late Quaternary drainage dynamics in northern Brazil based on the study of a large paleochannel from southwestern Marajó Island

    Full Text Available Marajó Island shows an abundance of paleochannels easily mapped in its eastern portion, where vegetation consists mostly of savannas. SRTM data make possible to recognize paleochannels also in western Marajó, even considering the dense forest cover. A well preserved paleodrainage network from the adjacency of the town of Breves (southwestern Marajó Island was investigated in this work combining remote sensing and sedimentological studies. The palimpsest drainage system consists of a large meander connected to narrower tributaries. Sedimentological studies revealed mostly sharp-based, fining upward sands for the channelized features, and interbedded muds and sands for floodplain areas. The sedimentary structures and facies successions are in perfect agreement with deposition in channelized and floodplain environments, as suggested by remote sensing mapping. The present study shows that this paleodrainage was abandoned during Late Pleistocene, slightly earlier than the Holocene paleochannel systems from the east part of the island. Integration of previous studies with the data available herein supports a tectonic origin, related to the opening of the Pará River along fault lineaments. This would explain the disappearance of large, north to northeastward migrating channel systems in southwestern Marajó Island, which were replaced by the much narrower, south to southeastward flowing modern channels.A Ilha do Marajó mostra uma abundância de paleocanais que são facilmente mapeáveis em sua porção leste, onde a vegetação consiste principalmente em savanas.

    Full Text Available Abstract Bathygobius soporator (Valenciennes, 1837 is one of the most common fishes in tide pools in the estuary of Pará state, and has an omnivorous feeding habit. This study examined the diet of the species in Maiandeua Island, and aimed to: (i describe the diet of B. soporator through indexes based on the occurrence and weight of consumed items; and (ii evaluate if there is variation in diet composition between males and females. Frequency of Occurrence, frequency of weight and Alimentary Index were calculated for each item, and differences in the diet composition of males and females were observed through multivariate analyses (ANOSIM, NMDS and SIMPER. Bathygobius soporator presented carnivorous feeding habit, eating mainly crustaceans, and differences among males and females were observed, males consuming smaller amounts of crustaceans and including algae in their diet.

    Full Text Available Visual records, radio interviews and onboard observations of the fishing activities during a 58 days scientific expedition to Trindade Island and the Martin Vaz Archipelago were obtained from February to April 2007. The regular activities of four different fisheries were observed: pelagic longline, bottom line, trolling and handline. These fisheries caused mortality of at least seven species with some level threat, according to the International Union for Conservation of Nature list. The establishment of specific restriction norms for hook-and-line activities around the oceanic islands was seen as an alternative for the conservation of the ichthyofauna of the region. Satellite monitoring to track the fishery vessels could be established through the national program as another legal mean to diminish fishing the impact.Reportamos atividades de pesca comerciais no complexo insular mais afastado da costa brasileira: Ilha da Trindade e Arquipélago Martin Vaz. As atividades foram estudadas através de embarques e entrevistas com os mestres e pescadores das embarcações durante uma expedição cientifica realizada entre fevereiro e abril de 2007. Quatro modalidades de atividades de pesca são realizadas na região, capturando ao menos sete espécies que possuem algum risco de extinção. O estabelecimento de normas específicas de restrição para atividades que pescam sobre os recifes das ilhas é uma alternativa para a conservação das espécies ameaçadas.

    Full Text Available The process of land occupation by the state of Paraná practically decimated its forests. Presently, only 7% from a total area of 83.41% is covered by forests. Most of them are now concentrated in the "Serra do Mar" and in the Iguaçu National Park. With regard to forest cover the most critical region is situated in the northwestern of the state with less than 1% of its area covered by forest. This restricted area mainly consists of conservation units and the islands of the high Paraná River floodplain. The present study consists of a spatial and multi-temporal analysis of deforestation and the quantification of the remnant forests on Porto Rico island (22º45'S; 53º15'W, which have their occupation history linked to the colonization process of the region. Historical aerial photographs of this region were used and the relationship of deforestation with the process of colonization and social transformation of the region is discussed.O processo de ocupação das terras do Paraná praticamente dizimou as florestas do Estado, que originalmente possuía 83,41% de sua área total coberta com florestas. Atualmente remanescem aproximadamente 7% da área com florestas, concentradas na Serra do Mar e no Parque Nacional do Iguaçu. Na região noroeste, a situação é mais crítica, com menos de 1% de sua área coberta por florestas, concentradas, principalmente, em unidades de conservação e nas ilhas da planície de inundação do alto rio Paraná. Esta planície é formada por uma ampla calha aluvial, com inúmeros canais, lagoas e ilhas, que têm sua história de ocupação ligadas ao processo de colonização na região. Neste trabalho, é realizada uma análise espacial e multi-temporal dos desflorestamentos e uma quantificação das florestas remanescentes da ilha Porto Rico (22º45'S; 53º15'W, por meio de fotografias aéreas históricas da região e discutidas as relações destes desflorestamentos com os processo de colonização e transforma

    Full Text Available The genus Opuntia is worldwide known for its ecological, ornamental and agronomic importance. Some species became pests in the countries in which they where introduced, and as biological control, Cactoblastis cactorum (Lepidoptera: Pyralidae larvae, originary from Argentina, were used. However, the effect of the attack of this piralid on native cactus has yet not been elucidated. The objective of this study was to detect and to quantify the predation of C. cactorum on Opuntia monacantha. The study was carried out from September to November of 2004, along pre-defined tracks, on a sand bank vegetation area, between the Mole and Galheta beaches in the Santa Catarina island (27º35’83.1’’S e 48º25’70.6’’W. All the studied plants (n = 20 presented some damage caused by C. cactorum. The proportion of unpredated cladodes (68% and fruits (85% was higher than the predated ones. Terminal cladodes were highly predated structures and presented the highest number of larvae inside. Seed loss in the predated fruits was high. The remaining areole of the predated cladodes and fruits differentiated into sprouts and routs and formed new plants. O. monacantha, despite of being predated by C. cactorum larvae, apparently possess defense mechanisms which assure the maintenance of its populations.

    This true-color image of the Galapagos Islands was acquired on March 12, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra satellite. The Galapagos Islands, which are part of Ecuador, sit in the Pacific Ocean about 1000 km (620 miles) west of South America. As the three craters on the largest island (Isabela Island) suggest, the archipelago was created by volcanic eruptions, which took place millions of years ago. Unlike most remote islands in the Pacific, the Galapagos have gone relatively untouched by humans over the past few millennia. As a result, many unique species have continued to thrive on the islands. Over 95 percent of the islands' reptile species and nearly three quarters of its land bird species cannot be found anywhere else in the world. Two of the more well known are the Galapagos giant tortoise and marine iguanas. The unhindered evolutionary development of the islands' species inspired Charles Darwin to begin The Origin of Species eight years after his visit there. To preserve the unique wildlife on the islands, the Ecuadorian government made the entire archipelago a national park in 1959. Each year roughly 60,000 tourists visit these islands to experience what Darwin did over a century and a half ago. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

    1996-08-01

    Brazil is South America's largest country and home to nearly half of the continent's people. Despite solid economic growth, Brazil has one of the world's widest income disparities. In the early 1990s, nearly 40% of urban and 66% of rural Brazilians lived in poverty. The streets of Brazil's cities are home to a large population of street children. Although it is difficult to estimate, 10 million children and youths may be either homeless or making a meager living off of the streets. Street children may be linked to prostitution and drugs and be the targets or perpetrators of violence. Child labor is an issue in Brazil. Today an estimated 30% of rural children and 9% of urban children ages 10-13 work in the formal economy. In some rural areas, 60% of workers are ages 5-17. Child labor also contributes to Brazil's relatively low educational attainment levels. UNICEF estimates that around 1990 only 1/3 of all Brazilian children continued on to secondary school, compared to 74% and 47%, respectively, for the Latin America and Caribbean regions. Immunization rates among Brazil's children are rising but still lag slightly behind regional averages. The mortality rate for children under age 5 decreased dramatically from 181 deaths for every 1000 live births in 1960 to 61/1000 in 1994. During the same time period, the average number of children born to a woman during her lifetime dropped from 6.2 to 2.8. This fertility decline is related in part to increased access to and acceptance of family planning. Contraceptive prevalence, including traditional and modern methods, is around 66%, with female sterilization and the pill being the most popular methods. Brazil's abortion rates are high, despite laws limiting access to abortion services. One estimate suggests that about 30% of all pregnancies are terminated through abortion each year.

    Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators such as marmosets and coatis, introduced more than 20 years ago. This indiscriminate introduction of mammals may have affected directly the ...

    This work reports the results of a technical evaluation of Solar Home Systems project at Parque Estadual da Ilha do Cardoso, SP, Brazil. The systems belong to the CESP's commercial program called ECOWATT, initiated in 1997. During the visit were registered 75 systems (2 churches, 4 schools and 69 houses). In some houses were done tests of charge control operation and performance. The work shows some problems at the design and at the technical standard. In our valuation, some systems should have been smaller and some bigger depending the needs and the payment capacity of each family.In this sense, a study of caicara's way of living were missing, as well as its difference at social and economic class. The results revealed that many simple aspects, but important for the exit of the project were not take into account. (author)

    The junctions of the Amazon and the Rio Negro Rivers at Manaus, Brazil. The Rio Negro flows 2300 km from Columbia, and is the dark current forming the north side of the river. It gets its color from the high tannin content in the water. The Amazon is sediment laden, appearing brown in this simulated natural color image. Manaus is the capital of Amazonas state, and has a population in excess of one million. The ASTER image covers an area of 60 x 45 km. This image was acquired on July 16, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface

  19. Arctic ice islands

    1988-01-01

    The development of offshore oil and gas resources in the Arctic waters of Alaska requires offshore structures which successfully resist the lateral forces due to moving, drifting ice. Ice islands are floating, a tabular icebergs, up to 60 meters thick, of solid ice throughout their thickness. The ice islands are thus regarded as the strongest ice features in the Arctic; fixed offshore structures which can directly withstand the impact of ice islands are possible but in some locations may be so expensive as to make oilfield development uneconomic. The resolution of the ice island problem requires two research steps: (1) calculation of the probability of interaction between an ice island and an offshore structure in a given region; and (2) if the probability if sufficiently large, then the study of possible interactions between ice island and structure, to discover mitigative measures to deal with the moving ice island. The ice island research conducted during the 1983-1988 interval, which is summarized in this report, was concerned with the first step. Monte Carlo simulations of ice island generation and movement suggest that ice island lifetimes range from 0 to 70 years, and that 85% of the lifetimes are less then 35 years. The simulation shows a mean value of 18 ice islands present at any time in the Arctic Ocean, with a 90% probability of less than 30 ice islands. At this time, approximately 34 ice islands are known, from observations, to exist in the Arctic Ocean, not including the 10-meter thick class of ice islands. Return interval plots from the simulation show that coastal zones of the Beaufort and Chukchi Seas, already leased for oil development, have ice island recurrences of 10 to 100 years. This implies that the ice island hazard must be considered thoroughly, and appropriate safety measures adopted, when offshore oil production plans are formulated for the Alaskan Arctic offshore. 132 refs., 161 figs., 17 tabs.

    Full Text Available ABSTRACT The island rule suggests that, when mainland animals are isolated on islands, large animals tend to become smaller, while small animals tend to become larger. A small frog in eastern Brazil, Phyllodytes luteolus (Wied-Neuwied, 1824, is widely distributed in association with bromeliads. At the end of the last glaciation, parts of the mainland became islands due to rising sea levels, thereby isolating frog populations on these islands. If the island rule holds, we predicted that frogs on islands would tend to be larger than frogs on the mainland. We compared sizes (weight and length of 30 randomly selected male frogs from the mainland with 30 from an island in the state of Espírito Santo, Brazil. We also sampled population density on the island and mainland because concurrent with changing sizes, depending on the causal relationship, density may also change. As predicted, island frogs tended to be larger (both in snout-vent length and weight and were much more abundant. While not specifically addressed in this study, the absence of predators and interspecific competitors may explain both of these trends.

  5. Paradise Islands? Island States and Environmental Performance

    2016-03-01

    Full Text Available Island states have been shown to outperform continental states on a number of large-scale coordination-related outcomes, such as levels of democracy and institutional quality. The argument developed and tested in this article contends that the same kind of logic may apply to islands’ environmental performance, too. However, the empirical analysis shows mixed results. Among the 105 environmental outcomes that we analyzed, being an island only has a positive impact on 20 of them. For example, island states tend to outcompete continental states with respect to several indicators related to water quality but not in aspects related to biodiversity, protected areas, or environmental regulations. In addition, the causal factors previously suggested to make islands outperform continental states in terms of coordination have weak explanatory power in predicting islands’ environmental performance. We conclude the paper by discussing how these interesting findings can be further explored.

  6. Electrochemical island growth

    Science.gov (United States)

    Guo, Lian

    The ability to independently dictate the shape and crystal orientation of islands in electrocrystallization remains a significant challenge. The main reason for this is that the complex interplay between the substrate, nucleation, and surface chemistry are not fully understood. Here the kinetics of 3D island growth for copper on ruthenium oxide is studied. The small nucleation overpotential leads to enhanced lateral growth and the formation of hexagonal, disk-shaped islands. The amorphous substrate allows the nuclei to achieve the thermodynamically favorable orientation, i.e. a surface normal. Island growth follows power law kinetics in both lateral and vertical directions. At shorter times, the two growth exponents are equal to 1/2 whereas at longer times lateral growth slows down while vertical growth speeds up. Accordingly, a growth mechanism is proposed, wherein the lateral growth of disk-shaped islands is initiated by attachment of Cu adatoms on the ruthenium oxide surface onto the island periphery while vertical growth is initiated by 2D nucleation on the top terrace and followed by lateral step propagation. These results indicate three criteria for enhanced lateral growth in electrodeposition: (i) a substrate that leads to a small nucleation overpotential, (ii) fast adatom surface diffusion on substrate to promote lateral growth, and (iii) preferential anion adsorption to stabilize the basal plane. The surface roughness evolution, during isolated island growth, island coalescence, and continuous film growth, has also been studied as a function of island shape and island density. It is shown that the surface width wsat(l,t) initially follows anomalous scaling in the isolated island growth regime but exhibits normal scaling during the early stages of continuous film growth. Furthermore, the short length scale roughness is dependent primarily on island shape while the long length scale roughness is dependent on island density. Electrochemical deposition of

    Full Text Available Banana: from origin to market. Cultivated bananas are giant herbaceous plants within the genus Musa. They are both sterile and parthenocarpic. There are well over a thousand domesticated Musa cultivars, they are mostly triploid (a few are diploid or tetraploid and are derived from crosses between two wild species, Musa acuminata and Musa balbisiana. In terms of production, bananas are the fourth agricultural product after rice, wheat, and maize. They constitute the basis of food security for many people. Cropping systems vary widely around the world and contrasting objectives are encountered: consumption by the producer, sale on local or national markets, export, etc. Cooking bananas, including plantains, must be distinguished from dessert bananas, which constitute a major international trade. This international trade started only in the early 1900s but it has since grown continuously. Banana is currently the most exported fruit, in terms of both value and quantity. Despite the high genetic diversity found within the genus Musa, the export market is mainly based on single Cavendish. There are major challenges to banana production from biotic or abiotic stresses to continue to meet the criteria of sustainability, quality and yield that are imposed.

Na busca de um cultivo em pequena escala para uso das comunidades litorâneas foi implantado um cultivo experimental com H. musciformis, na Ilha da Marambaia, RJ (43º59'35" W e 23º04'00" S. Ao todo foram testadas nove técnicas de fixação da alga nas unidades experimentais de maricultura (UEM. Nos experimentos realizados entre a primavera de 2003 e o outono de 2004, as taxas de crescimento geralmente foram negativas. Entre os invernos de 2004 e 2005, foram na maioria positivas. O fitobentos próximo à UEM foi analisado para verificar o crescimento dessa espécie na assembléia e no cultivo. Observou-se maior percentual de anfípodas e de matéria orgânica nas UEM e a presença de carposporófitos em épocas de baixa salinidade em ambos os locais. Atribuiu-se o baixo rendimento da taxa de crescimento aos fatores ambientais como: ressacas, aderência de matéria orgânica nas algas, herbivoria e danos as UEM por ação antrópica.

    Full Text Available O trabalho artesanal persiste no país, cuja abordagem deve considerar particularidades sociais distintas das relações assalariadas. O objetivo foi analisar o processo de trabalho artesanal e suas relações com a saúde em uma comunidade de pescadores artesanais, particularmente nas atividades de pesca extrativa de mariscos. Estudar as cadências e contingenciamentos de tempo e outras condições de trabalho relacionadas ao desenvolvimento de patologias como lesões por esforços repetitivos - LER. Realizou-se um estudo qualitativo, ou etnográfico, no período de 2005 a 2007, em uma comunidade de 800 habitantes, situada em Ilha de Maré - Bahia. Foram entrevistados 30 pescadores e familiares, observados as atividades no trabalho e os casos suspeitos de LER encaminhados para serviço ambulatorial especializado. Evidenciou-se a gravidade das condições de trabalho, em particular para enfermidades LER. Em um modo de extração de mariscos, verificou-se a frequência média de 10.200 movimentos repetitivos por hora, enquanto, para a atividade de digitador, a norma oficial estabelece o limite de 8.000 toques por hora. Concluiu-se que as mariscadeiras devem ser incluídas dentre os grupos sociais de riscos que realizam esforços excessivos e repetitivos do sistema músculo-esquelético nas atividades do trabalho.Non-industrial labor is still widespread in Brazil. An appropriate approach ought to consider different social specificities from those of salaried-work relations. The scope was to examine non-industrial work practices, specifically those of extractive shellfishing, and their relation to health conditions in a small-scale fishing community. It focused on the cadences and time contingencies, as well as other working conditions, related to the development of ailments such as repetitive strain injury -RSI.

    Melville Island, just off the coast of Darwin, Northern Territory, Australia (11.5S, 131.0E) is a sparsely inhabited tropical island with heavy woodland concentrations. The widespread and prominant smoke plumes were most likely set to renew pasture under open canopy woodland. Soil erosion is almost non- existant as can be seen by the clear and clean river flow. The offshore sediments are coastal current borne deposits from King Sound to the west.

  18. Multi-modal homing in sea turtles: modeling dual use of geomagnetic and chemical cues in island-finding

    Directory of Open Access Journals (Sweden)

    Courtney S Endres

    2016-02-01

    Full Text Available Sea turtles are capable of navigating across large expanses of ocean to arrive at remote islands for nesting, but how they do so has remained enigmatic. An interesting example involves green turtles (Chelonia mydas that nest on Ascension Island, a tiny land mass located approximately 2000 km from the turtles' foraging grounds along the coast of Brazil. Sensory cues that turtles are known to detect, and which might hypothetically be used to help locate Ascension Island, include the geomagnetic field, airborne odorants, and waterborne odorants. One possibility is that turtles use magnetic cues to arrive in the vicinity of the island, then use chemical cues to pinpoint its location. As a first step toward investigating this hypothesis, we used oceanic, atmospheric, and geomagnetic models to assess whether magnetic and chemical cues might plausibly be used by turtles to locate Ascension Island. Results suggest that waterborne and airborne odorants alone are insufficient to guide turtles from Brazil to Ascension, but might permit localization of the island once turtles arrive in its vicinity. By contrast, magnetic cues might lead turtles into the vicinity of the island, but would not typically permit its localization because the field shifts gradually over time. Simulations reveal, however, that the sequential use of magnetic and chemical cues can potentially provide a robust navigational strategy for locating Ascension Island. Specifically, one strategy that appears viable is following a magnetic isoline into the vicinity of Ascension Island until an odor plume emanating from the island is encountered, after which turtles might either: (1 initiate a search strategy; or (2 follow the plume to its island source. These findings are consistent with the hypothesis that sea turtles, and perhaps other marine animals, use a multi-modal navigational strategy for locating remote islands.

    Lesser, Jeffrey

    2014-01-01

    Many countries in the Americas describe themselves as "nations of immigrants." In the United States, the myth of the "promised land" suggests that foreigners better themselves upon arrival because the nation is intrinsically great. In Brazil, however, the relationship between immigration and national identity is different. Many intellectuals, politicians, and cultural and economic leaders saw (and see) immigrants as improving an imperfect nation that has been tainted by the history of Portuguese colonialism and African slavery. As a result, immigrants were often hailed as saviors because they modified and improved Brazil, not because they were improved by Brazil. This "improvement" took place through absorption, mixture and with the use of increasingly flexible racial and ethnic categories.

    This article focuses on scientific integrity and the identification of predisposing factors to scientific misconduct in Brazil. Brazilian scientific production has increased in the last ten years, but the quality of the articles has decreased. Pressure on researchers and students for increasing scientific production may contribute to scientific misconduct. Cases of misconduct in science have been recently denounced in the country. Brazil has important institutions for controlling ethical and safety aspects of human research, but there is a lack of specific offices to investigate suspected cases of misconduct and policies to deal with scientific dishonesty.

  5. Small Island Visitor Attractions

    Directory of Open Access Journals (Sweden)

    Haven Allahar

    2015-03-01

    Full Text Available This article proposes a process framework for developing and managing visitor attractions (VA in small island developing states with Trinidad and Tobago, a two-island state in the Caribbean, as the case study. An extensive literature review was conducted, supported by field observations, individual depth interviews, and small and large focus group meetings. The process framework identified four sets of processes: national policy formulation and legislation; inventory, classification, evaluation, and ranking of VA; general operations management involving project management activities; and site specific activities of development, operations, and maintenance. The value of the framework lies in the fact that no similar framework applicable to small islands was covered in the literature and validation was obtained from a panel of experts and a cross section of tourism stakeholders in Tobago.

    Full Text Available A global review of islands and their connections with astronomy throughout history up to the contemporary times suggests eight compelling, distinct yet interlocking reasons why islands have been and remain so important to astronomy and astronomers. Islands constitute favourable locations for various types of astronomy-related activities: from tracking satellites and monitoring significant celestial events, to providing exceptional locations to jurisdictions with mandated dark and unpolluted skies. They appeal for their favourable longitude and (especially southern latitude, as well as for their disposition towards the conditions that the scientific community may expect in an ideal world: relatively clear viewing conditions from a secure, self-contained platform that is, however, endowed with connectivity. This article is written as a contribution to the International Year of Astronomy (2009.

    Full Text Available Distribution records of poorly-known species are currently the most explored theme in the Brazilian seabird literature. If properly evaluated, this kind of information can improve our knowledge on distribution, migration and status of occurrence of these species. In this note we present new records for six species of poorly-known seabirds in the Brazilian coast, reviewing distribution records and defining their status of occurrence in the country. We consider Chionis albus (Gmelin, 1789 a pseudo-vagrant in Brazil and define its status as a scarce seasonal visitor from southern South America. We present the first records of Leucophaeus atricilla (Linnaeus, 1758 for Trindade Island, and of Leucophaeus pipixcan (Wagler, 1831 for the state of Rio Grande do Sul, and determined that the former is a vagrant in eastern Brazil and the latter a vagrant across the country. Anous stolidus (Linnaeus, 1758 is a vagrant in southernmost Brazil. We were unable to determine if records of Chlidonias niger (Linnaeus, 1758 for Brazil and southern South America refer to vagrancy or pseudo-vagrancy. Additionally, we verified the occurrence of breeding individuals of Anous minutus Boie, 1844 on Martin Vaz Island and confirmed that there is no evidence of breeding on neighboring Trindade Island.

    Astronomer priests or "skywatchers" on Easter Island lived in stone towers that were used as observatories and built stone markers in the periphery that indicated the heliacal rising of certain stars that served to indicate the arrival of marine birds, turtles, the offshore fishing season, and times for planting and harvest. Petroglyphs related to such sites depict outriggers, fishhooks, pelagic fish, and turtles and supposedly represented a star map. In this chapter, we analyze a set of such skywatchers dwellings, and stone markers located upon the North coast of Easter Island that have astronomic orientations, its related petroglyphs, and the relations between these directions with their yearly activities and their ritual calendar.

    The Long Island Solar Farm (LISF) is a remarkable success story, whereby very different interest groups found a way to capitalize on unusual circumstances to develop a mutually beneficial source of renewable energy. The uniqueness of the circumstances that were necessary to develop the Long Island Solar Farm make it very difficult to replicate. The project is, however, an unparalleled resource for solar energy research, which will greatly inform large-scale PV solar development in the East. Lastly, the LISF is a superb model for the process by which the project developed and the innovation and leadership shown by the different players.

Methods:By using cluster sampling , 492 children aged 2-7 years in kindergartens in Banan district of Chongqing were selected .A cross-sectional nutrition and health survey was conducted , including the clinical examination , anthropometry , laboratory test and dietary survey .Results: Among the children surveyed, 229 were boys, and 263 girls, the mean age was (4.54 ±0.87) years, height (107.50 ± 7.20) cm, and weight (18.42 ±3.41) kg, the mean value of plasma vitamin A was (1.04 ±0.30)μmol/L.The prevalence of marginal vitamin A deficiency ( MVAD) was 43.5%.No cases of severe clinical vitamin A deficiency were found (plasma vitamin A≤0.35μmol/L).Clinical examination found no conjunctiva, corneaor skin abnormalities, and no Bitot’s spots.Prevalence of the last two weeks colds were 27.4% (135/492), no diarrhea and other gastrointestinal or digestive diseases were found .The proportion of insufficient dietary vitamin A intake ( <600 μg RE/d) was as high as 50.0%.By using correlation analysis, plasma retinol concentrations were related to dietary vitamin A intake (r=0.162, P<0.001), and to dietary energy intake (r=0.107, P=0.017).After adjustment for the effects of other non-dietary factors on vitamin A deficiency , the multivariate logistic regression showed that vitamin A-rich foods of liver intake=0 g/d (OR=1.95, 95% CI:1.05-3.61, P=0.034), vitamin A-rich fruits intake=0 g/d (OR =1.55, 95% CI: 1.03 -2.33, P =0.034), vitamin A-rich vegetables intake<200 g/d (OR=3.47, 95%CI:1.37-8.75, P=0.009) were important risk factors of vitamin A deficiency .But we had not found the correlation between the intake of meat , eggs and milk and vita-min A deficiency .Conclusion:Dietary factors may be the major risk factor of vitamin A deficiency in the three kindergartens

  15. Chikungunya risk for Brazil

    Raimunda do Socorro da Silva Azevedo

    2015-01-01

    Full Text Available This study aimed to show, based on the literature on the subject, the potential for dispersal and establishment of the chikungunya virus in Brazil. The chikungunya virus, a Togaviridae member of the genusAlphavirus, reached the Americas in 2013 and, the following year, more than a million cases were reported. In Brazil, indigenous transmission was registered in Amapa and Bahia States, even during the period of low rainfall, exposing the whole country to the risk of virus spreading. Brazil is historically infested by Ae. aegypti and Ae. albopictus, also dengue vectors. Chikungunya may spread, and it is important to take measures to prevent the virus from becoming endemic in the country. Adequate care for patients with chikungunya fever requires training general practitioners, rheumatologists, nurses, and experts in laboratory diagnosis. Up to November 2014, more than 1,000 cases of the virus were reported in Brazil. There is a need for experimental studies in animal models to understand the dynamics of infection and the pathogenesis as well as to identify pathophysiological mechanisms that may contribute to identifying effective drugs against the virus. Clinical trials are needed to identify the causal relationship between the virus and serious injuries observed in different organs and joints. In the absence of vaccines or effective drugs against the virus, currently the only way to prevent the disease is vector control, which will also reduce the number of cases of dengue fever.

    Objective. To determine the incidence of bone islands in leprosy patients. Design. X-rays of feet and hands of patients with Hansen`s disease (leprosy) were reviewed retrospectively. A second group of related age- and sex-matched patients who did not have Hansen`s disease was used for control purposes. Controls had undergone hand or foot X-rays during diagnosis of other pathologies. The patients with Hansen`s disease were compared with the control group, and were also analyzed as subgroups with different types of leprosy. The results were subjected to statistical analysis. Patients. Ninety patients with Hansen`s disease were randomly selected for this study. Patients who had had ulcers on hands or feet were excluded from the study. Results and conclusions. Bone islands were demonstrated in 20 patients with Hansen`s disease; no bone islands were observed in the controls. This was statistically significant (P<0.01). Bone islands were only seen in patients with lepromatous leprosy and borderline types but were not demonstrated in patients with tuberculoid leprosy. There was also a statistically significant relationship for a disease duration of 15 years or more. The cause of this raised incidence of enostosis in leprosy patients is not clear, but there may be a genetic predisposition in patients with leprosy, or it may be a side effect of leprosy, especially the lepromatous form.

    Santa Rosa Island (SRI) is the second-largest of the California Channel Islands. It is one of 4 east–west aligned islands forming the northern Channel Islands chain, and one of the 5 islands in Channel Islands National Park. The landforms, and collections of landforms called landscapes, of Santa Rosa Island have been created by tectonic uplift and faulting, rising and falling sea level, landslides, erosion and deposition, floods, and droughts. Landscape features, and areas delineating groups of related features on Santa Rosa Island, are mapped, classified, and described in this paper. Notable landscapes on the island include beaches, coastal plains formed on marine terraces, sand dunes, and sand sheets. In this study, the inland physiography has been classified into 4 areas based on relief and degree of fluvial dissection. Most of the larger streams on the island occupy broad valleys that have been filled with alluvium and later incised to form steep- to vertical-walled arroyos, or barrancas, leaving a relict floodplain above the present channel. A better understanding of the processes and mechanisms that created these landscapes enhances visitors’ enjoyment of their surroundings and contributes to improving land and resource management strategies in order to optimize and balance the multiple goals of conservation, preservation, restoration, and visitor experience.

  10. Islands of the Arctic

    2004-02-01

    Few environments on Earth are changing more dramatically than the Arctic. Sea ice retreat and thinning is unprecedented in the period of the satellite record. Surface air temperatures are the warmest in centuries. The biology of Arctic lakes is changing like never before in millennia. Everything is pointing to the meltdown predicted by climate model simulations for the next 100 years. At the same time, the Arctic remains one of the most pristine and beautiful places on Earth. For both those who know the Arctic and those who want to know it, this book is worth its modest price. There is much more to the Arctic than its islands, but there's little doubt that Greenland and the major northern archipelagos can serve as a great introduction to the environment and magnificence of the Arctic. The book uses the islands of the Arctic to give a good introduction to what the Arctic environment is all about. The first chapter sets the stage with an overview of the geography of the Arctic islands, and this is followed by chapters that cover many key aspects of the Arctic: the geology (origins), weather and climate, glaciers, ice sheets, sea ice, permafrost and other frozen ground issues, coasts, rivers, lakes, animals, people, and environmental impacts. The material is pitched at a level well suited for the interested layperson, but the book will also appeal to those who study the science of the Arctic.

  11. [Salmonella pathogenicity islands].

    Salmonella species are facultative intracellular pathogenic bacteria. They can invade macrophages, dendritic and epithelial cells. The responsible virulence genes for invasion, survival, and extraintestinal spread are located in Salmonella pathogenicity islands (SPIs). SPIs are thought to be acquired by horizontal gene transfer. Some of the SPIs are conserved throughout the Salmonella genus, and some of them are specific for certain serovars. There are differences between Salmonella serotypes in terms of adaptation to host cell, virulence factors and the resulting infection according to SPA presence and characteristics. The most important Salmonella virulence gene clusters are located in 12 pathogenicity islands. Virulence genes that are involved in the intestinal phase of infection are located in SPI-1 and SPI-2 and the remaining SPIs are required for intracellular survival, fimbrial expression, magnesium and iron uptake, multiple antibiotic resistance and the development of systemic infections. In addition SPIs, Sigma ss (RpoS) factors and adaptive acid tolerance response (ATR) are the other two important virulence factors. RpoS and ATR found in virulent Salmonella strains help the bacteria to survive under inappropriate conditions such as gastric acidity, bile salts, inadequate oxygen concentration, lack of nutrients, antimicrobial peptides, mucus and natural microbiota and also to live in phagosomes or phagolysosomes. This review article summarizes the data related to pathogenicity islands in Salmonella serotypes and some factors which play role in the regulation of virulence genes.

  12. MARICULTURE ON CROATIAN ISLANDS

    Full Text Available The first attempts of intensive mariculture in Croatia commenced at the very beginning of 1980’s. The mid-eighties brought an expansion of mariculture production, which has been continuously increasing. A few different marine organisms are intensively cultured - both fish and shellfish. Among them commercially most important and highly valued species are sea bass Dicentrarchus labrax and sea bream Sparus aurata. Mussel Mytilus galloprovincialis and oyster Ostrea edulis are the most important shellfish. Fish species such as dentex Dentex dentex, red sea bream Pagrus major and sheepshead bream Puntazzo puntazzo are reared too, but in a rather small quantities. Only recently the rearing, on-growing- of bluefin tuna Thunnus thynnus started in Croatia. The juveniles (70% are reared in a Croatian hatcheries, and 30% has to be imported mainly from Italy and France, due to a higher demand for this kind of culture among the small growers. Croatian part of Adriatic sea possesses a number of geomorfologicaly suitable sites and meteorological conditions which determined the choice - type - of intensive culture. All fish species are reared in a floating cages. The choice of cages i. e. semi off-shore or floating frames, size, rearing volume and design depend on the investors personal preference. The annual turnouf of a market size bass was about 600t and 300t bream in 1996., by 10 island farms which is 70% of total production in Croatia. Including other cultured fish species last year production was up to 1000t, and it™s being estimated to be about 1300t in the following year. The shellfish production on the islands is usually individual attempt of farmers, producing minor quantities mostly in polyculture. This production has bigger potential but it’s limited owing to the EU quality control regulations which do not allow the export, and by domestic market which has drastically decreased due to the collapse of tourism during the recent war.

    2006-03-17

    Easter Island (Rapa Nui) provides a model of human-induced environmental degradation. A reliable chronology is central to understanding the cultural, ecological, and demographic processes involved. Radiocarbon dates for the earliest stratigraphic layers at Anakena, Easter Island, and analysis of previous radiocarbon dates imply that the island was colonized late, about 1200 A.D. Substantial ecological impacts and major cultural investments in monumental architecture and statuary thus began soon after initial settlement.

    2015-01-01

    Full Text Available Under conditions of high stress, interactions between species can be positive. Islands of perennial vegetation can improve the conditions of the understory and facilitate the establishment of herbaceous plants. The hypothesis of this study is that islands of perennial vegetation in an area of caatinga harbor, a greater richness, diversity and density of herbaceous plants, and that individuals reach a greater height and diameter than in open spaces. The study was conducted in Petrolândia, Pernambuco, Brazil. Twenty-seven plots were installed in the center of the islands, 38 at the edge of the islands (in a total of 38 islands and 35 in the open spaces. A total of 51 species were recorded in the center and 55 on the edge of the islands and 48 in the open spaces. The mean richness of the open spaces was lower than on the islands. The diversity was greater in the center of the island and became less on the edge of the island and in the open spaces. The mean density was lower in the open spaces than on the islands. The mean density at the edge of the islands was greater than in the center of the islands. There was no difference in mean diameter of herbaceous plants. The mean height of the individuals was higher in the center of the islands. The herbaceous community growing on the islands exhibited higher richness, diversity, density and height than in open spaces. Thus, islands of perennial vegetation facilitate the establishment of herbaceous species.

  16. Renewable energy islands in Europe

    Energy Technology Data Exchange (ETDEWEB)

    Oestergaard, Iben [ed.

    1998-12-31

    This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

    Full Text Available In this work, we intend to describe the reproductive dynamics of Sterna hirundinacea in an island from South Brazil. We studied the reproductive biology of this species in its natural environment and provide data on their growth, survival, and reproductive success in Ilha dos Cardos, Santa Catarina, South Brazil. Samplings were carried out daily on the island throughout the reproductive seasons of 2003, 2005, and 2006 and the different stages of development of the chicks were characterized according to age, length of the beak, and plumage characteristics. We provide a basic equation Lm=167.91 (1-e-0.062t--0.23 to determine the approximate age of individuals using their body mass. The main cause of chick mortality on the island was natural (63.17% in 2003, 81.41% in 2005, and 79.96% in 2006, whereas predation contributed to mortality in a proportion of 38.83% in 2003, 18.59% in 2005, and 20.04% in 2006. The absence in the area of the chicks’ main predator, Kelp gull (Larus dominicanus, the large number of chicks that reached the final stages of development, and their reproductive success demonstrate that Ilha dos Cardos is an important breeding site for the species in southern Brazil.

    The mite Varroa destructor is the main pest causing damage to apiculture worldwide. In Brazil and other parts of the world, where bees of African origin and their hybrids predominate, the bees can survive these mites without treatment. Studies have shown a correlation between the various genotypes of the mite and its fertility in different geographical regions. Information about mite genotype could be helpful in understanding the diverse effects and relationships of the mite with bees in different regions of the world. DNA analysis by RAPD technique has permitted identification of three distinct genotypes in the mite V. destructor, namely Russian, Japanese and Papua New Guinea. We found predominance of the Russian genotype in Brazil, along with other parts of South America, and in Cuba and Mexico. The Japanese genotype was exclusively found on Fernando de Noronha Island in Brazil.

  19. Potential geographic distribution and conservation of Audubon's Shearwater, Puffinus lherminieri in Brazil

    Directory of Open Access Journals (Sweden)

    Ana Cecília P.A. Lopes

    2014-01-01

    Full Text Available Audubon's Shearwater (Puffinus lherminieri Lesson 1839 is a tropical seabird occurring mainly between southern Canada and the southeast coast of Brazil. Puffinus lherminieri is considered Critically Endangered on the Brazilian Red List because it only occurs in two known localities, both of which contain very small populations. However, many offshore islands along the Brazilian coast are poorly known and the discovery of new colonies would be of considerable significance for the conservation of this species. The aim of this study was to estimate the potential geographic distribution of Audubon's Shearwater in Brazil, based on ecological niche model (ENM using Maxent algorithm with layers obtained from AquaMaps environmental dataset. The ENM was based on 37 records for reproduction areas in North and South America. The model yielded a very broad potential distribution, covering most of the Atlantic coast ranging from Brazil to the US. When filtered for islands along the Brazilian coast, the model indicates higher levels of environmental suitability near the states of São Paulo, Rio de Janeiro, Espírito Santo and Bahia. However, P. lherminieri prefers islands in environments with warm saline water. Thus, based on the influence of currents that act on the Brazilian coast we can infer undiscovered colonies are most likely to occur on islands on coast of Bahia, Espírito Santo and extreme north of the Rio de Janeiro. These should be intensively surveyed while the islands south of Cabo Frio should be discarded. The existence of new populations would have profound effects on the conservation status of this enigmatic and rarely seen seabird.

  1. Islands and non-islands in native and heritage Korean

    2016-02-01

    Full Text Available To a large extent, island phenomena are cross-linguistically invariable, but English and Korean present some striking differences in this domain. English has wh-movement and Korean does not, and while both languages show sensitivity to wh-islands, only English has island effects for adjunct clauses. Given this complex set of differences, one might expect Korean/English bilinguals, and especially heritage Korean speakers (i.e. early bilinguals whose L2 became their dominant language during childhood to be different from native speakers, since heritage speakers have had more limited exposure to Korean, may have had incomplete acquisition and/or attrition, and may show significant transfer effects from the L2. Here we examine islands in heritage speakers of Korean in the U.S. Through a series of four formal acceptability experiments comparing these heritage speakers with native speakers residing in Korea, we show that the two groups are remarkably similar. Both show clear evidence for wh-islands and an equally clear lack of adjunct island effects. Given the very different linguistic environment that the heritage speakers have had since early childhood, this result lends support to the idea that island phenomena are largely immune to environmental influences and stem from deeper properties of the processor and/or grammar. Similarly, it casts some doubt on recent proposals that islands are learned from the input.

    The Arctic islands are characterized by beautiful mountains and glaciers, in which the wildlife lives in delicate balance with its environment. It is a fragile region with a long history of exploration and exploitation that is now experiencing rapid environmental change. All of these themes are explored in Islands of the Arctic, a richly illustrated volume with superb photographs from the Canadian Arctic archipelago, Greenland, Svalbard and the Russian Arctic. It begins with the various processes shaping the landscape: glaciers, rivers and coastal processes, the role of ice in the oceans and the weather and climate. Julian Dowdeswell and Michael Hambrey describe the flora and fauna in addition to the human influences on the environment, from the sustainable approach of the Inuit, to the devastating damage inflicted by hunters and issues arising from the presence of military security installations. Finally, they consider the future prospects of the Arctic islands Julian Dowdeswell is Director of the Scott Polar Research Institute and Professor of Physical Geography at 0he University of Cambridge. He received the Polar Medal from Queen Elizabeth for his contributions to the study of glacier geophysics and the Gill Memorial Award from the Royal Geographical Society. He is chair of the Publications Committee of the International Glaciological Society and head of the Glaciers and Ice Sheets Division of the International Commission for Snow and Ice. Michael Hambrey is Director of the Centre for Glaciology at the University of Wales, Aberystwyth. A past recipient of the Polar Medal, he was also given the Earth Science Editors' Outstanding Publication Award for Glaciers (Cambridge University Press). Hambrey is also the author of Glacial Environments (British Columbia, 1994).

    The submental island flap is a reliable source of skin of excellent colour, contour and texture match for facial resurfacing and leaves a well hidden donor site. The flap is safe, rapid and simple to raise. We report on its use in 12 cases of facial or intraoral reconstruction. Complications were few. However, there was one case of complete flap loss following its use in a reverse flow manner, due to the presence of an unreported, but constant, valve in the venous system of the face. We believe this flap to be a worthwhile addition to the existing surgical armamentarium.

  7. Organizations as Designed Islands

    Directory of Open Access Journals (Sweden)

    Pasquale Gagliardi

    2009-05-01

    Full Text Available The literature and practice of organizational design are mostly based on simplistic conceptions which ignore recent theoretical developments in organizational studies. Conceiving of organizations as ‘designed islands’, it is argued, can contribute to a more solid theoretical foundation to organization theory, viewed as normative science. Relying on the work of Peter Sloterdijk, who describes the forms of life in space in terms of spheres, the heuristic power of the island metaphor is explored. What can be learnt from the art of isolating in order to construct lived organizational environments is then discussed, and the paradoxical relationship between connection and isolation is highlighted.

  8. Pine Island Glacier, Antarctica

    2001-01-01

    This pair of MISR images of the Pine Island Glacier in western Antarctica was acquired on December 12, 2000 during Terra orbit 5246. At left is a conventional, true-color image from the downward-looking (nadir) camera. The false-color image at right is a composite of red band data taken by the MISR forward 60-degree, nadir, and aftward 60-degree cameras, displayed in red, green, and blue colors, respectively. Color variations in the left (true-color) image highlight spectral differences. In the multi-angle composite, on the other hand, color variations act as a proxy for differences in the angular reflectance properties of the scene. In this representation, clouds show up as light purple. Blue to orange gradations on the surface indicate a transition in ice texture from smooth to rough. For example, the bright orange 'carrot-like' features are rough crevasses on the glacier's tongue. In the conventional nadir view, the blue ice labeled 'rough crevasses' and 'smooth blue ice' exhibit similar coloration, but the multi-angle composite reveals their different textures, with the smoother ice appearing dark purple instead of orange. This could be an indicator of different mechanisms by which this ice is exposed. The multi-angle view also reveals subtle roughness variations on the frozen sea ice between the glacier and the open water in Pine Island Bay.To the left of the 'icebergs' label are chunks of floating ice. Additionally, smaller icebergs embedded in the frozen sea ice are visible below and to the right of the label. These small icebergs are associated with dark streaks. Analysis of the illumination geometry suggests that these streaks are surface features, not shadows. Wind-driven motion and thinning of the sea ice in the vicinity of the icebergs is one possible explanation.Recently, Robert Bindschadler, a glaciologist at the NASA Goddard Space Flight Center discovered in Landsat 7 imagery a newly-formed crack traversing the Pine Island Glacier. This crack is

    2011-04-01

    A high-resolution rainfall climatology based on observations from the Tropical Rainfall Measuring Mission's Precipitation Radar (PR) instrument is used to evaluate the influence of small tropical islands on climatological rainfall. Islands with areas between one hundred and several thousand km2 are considered in both the Indo-Pacific Maritime Continent and Caribbean regions. Annual mean climatological (1997-2007) rainfall over each island is compared with that over the surrounding ocean region, and the difference is expressed as a percentage. In addition to total rainfall, rain frequency and intensity are also analyzed. Results are stratified into two 12 h halves of the diurnal cycle as well as eight 3 h periods, and also by a measure of each island's topographic relief. In both regions, there is a clear difference between larger islands (areas of a few hundred km2 or greater) and smaller ones. Both rain frequency and total rainfall are significantly enhanced over larger islands compared to the surrounding ocean. For smaller islands the enhancement is either negligibly small, statistically insignificant, or, in the case of Caribbean rain frequency, negative. The enhancement in total rainfall over larger islands is partly attributable to greater frequency and partly to greater intensity. A diurnal cycle in island enhancement is evident in frequency but not intensity, except over small Caribbean islands where the converse is true. For the larger islands, higher orography is associated with greater rainfall enhancements. The orographic effect is larger (percentagewise) in the Caribbean than in the Maritime Continent. Orographic precipitation enhancement manifests more strongly as increased frequency of precipitation rather than increased intensity and is present at night as well as during the day. The lack of a clear diurnal cycle in orographic enhancement suggests that much of the orographic rainfall enhancement is attributable to mechanically forced upslope flow

    The community structure of the reef fish fauna of Trindade Island, a volcanic oceanic island located 1160 km off the coast of Brazil, is described based on intensive visual censuses. Seventy-six species were encountered in 252 censuses, with mean ± S.E. of 99 ± 3 individuals and 15.7 ± 0.3 species 40 m(-2) transect. The average fish biomass, calculated from length-class estimation, was 22.1 kg 40 m(-2) transect. The species contributing most to biomass were, in decreasing order, Melichthys niger, Cephalopholis fulva, Kyphosus spp., Holocentrus adscensionis, Sparisoma amplum, Sparisoma axillare, Acanthurus bahianus and Epinephelus adscensionis. Carnivorous fishes were the largest trophic group in terms of biomass, followed by omnivores and roving herbivores. The two predominant types of reef habitat, fringing reefs built by coralline algae and rocky reefs made of volcanic boulders, showed significant differences in the biomass and the abundance of the trophic guilds. Within each habitat type, significant differences in species richness, density and biomass were detected among crest, slope and interface zones. Although similar in overall species composition to coastal reefs in Brazil, the fish fauna of Trindade Island shares certain characteristics, such as a high abundance of planktivores, with other Brazilian oceanic islands. Despite comparatively high fish biomass, including the macro-carnivorous species habitually targeted by fisheries, signs of overfishing were evident. These findings highlight the urgency for a conservation initiative for this isolated, unique and vulnerable reef system.

  11. Hyper abundant mesopredators and bird extinction in an Atlantic forest island

    2009-06-01

    Full Text Available Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators such as marmosets and coatis, introduced more than 20 years ago. This indiscriminate introduction of mammals may have affected directly the bird community, nowadays represented by 100 species comprised mainly by water-crossing birds, being 73 forest-dwelling species. A small component of these remnant bird species nests in tree holes and on the forest floor, null model analysis suggest that birds within these two nest types are under-represented on Anchieta Island. All guilds were affected negatively, but "opportunist insectivorous/omnivorous". Experiments using artificial nests showed a predation of 73% of nests on the floor while only 26% on the mainland. Camera traps recorded predation by coatis, agoutis, and opossums. The restoration of the bird community on this island is highly constrained by the high density of hyper abundant nest predators.

    Based on geochronological U-Pb studies, the age of Wrangel Island granitoids was estimated as Neoproterozoic (Cryogenian). Some granitoids contain zircons with inherited cores with an estimated age of 1010, 1170, 1200, and >2600 Ma, assuming the presence of ancient (Neoarchean-Mesoproterozoic) rocks in the Wrangel Island foundation and their involvement in partial melting under granitoid magma formation.

    This report summarises the findings of a study to investigate the regulatory, commercial and technical risks and benefits associated with the operation of distributed generation to power an islanded section of distributed network. A review of published literature was carried out, and UK generators were identified who could operate as part of an island network under the existing technical, regulatory, and safety framework. Agreement on case studies for consideration with distributed network operators (DNOs) is discussed as well as the quantification of the risks, benefits and costs of islanding, and the production of a case implementation plan for each case study. Technical issues associated with operating sections of network in islanded mode are described, and impacts of islanding on trading and settlement, and technical and commercial modelling are explored.

    ilhas de vegetação em cada platô.Islands of vegetation on rocky surfaces were studied on two plateaus at Pai Inácio Mountain (41°28'; 12°27'S in the Chapada Diamantina. Both plateaus have quartzite-sandstone outcrops interspersed with sandy, acidic soils at the summit between 1,100 and 1,170 meters above sea level, with a well-defined dry season. Islands are defined as clumps of one or more species of vascular plants completely surrounded by a rocky surface devoid of vascular plants. The study included 39 vegetation islands of different sizes on each plateau, with 63 herb and shrub species, of which 22 are common to both plateaus. Liliopsida species had the highest abundance, frequency and dominance, with Velloziaceae, Cyperaceae, Orchidaceae, Bromeliaceae, and Guttiferae families predominating on both plateaus. The chamaephyte life-form was also predominant. Similar species richness was detected on both plateaus, with most of the islands composed of up to five species. Four species groups were revealed using UPGMA and Jaccard´s similarity index, two groups with species typical of sunlit islands, one group with species from shadier sites, and a fourth composed of more generalist species. The Vellozia hemisphaerica - Trilepis lhotzkiana association was typical of rocky outcrops at Pai Inácio Mountain. Orchidaceae and Cyperaceae were the only families present in the two smallest island-size classes, while Guttiferae, Rubiaceae and Bromeliaceae were mostly present in the largest class. Variation in species composition and abundance between the two plateaus suggest environmental and isolation differences affecting the species spatial distribution in the vegetation islands on each plateau.

    1974-01-01

    Brazilian tungsten production, 85 percent of which is exported, comes almost entirely from scheelite-bearing tactites in northeast Brazil, and has reached an annual rate of about 2,000 metric tons (2,200 short tons) of scheelite concentrate with 70 percent WO3. Scheelite ore reserves, located principally in the State of Rio Grande do Norte, are estimated to be as high as 8,300,000 tons (9,100,000 short tons) containing 0.7 percent WO3. Minor deposits (or those about which only minimal information is available) of wolframite, with which some cassiterite is associated, are located in Sao Paulo, Santa Catarina, and Rio Grande do Sul. Both the scheelite and the wolframite deposits are considered . to be late Precambrian A (620 to 900 m.y.) or early Cambrian in age.

    Full Text Available OBJECTIVE: This study provides the clinical pathological characteristics of 1301 cases of pediatric/adolescent lymphomas in patients from different geographic regions of Brazil. METHODS: A retrospective analyses of diagnosed pediatric lymphoma cases in a 10-year period was performed. We believe that it represents the largest series of pediatric lymphomas presented from Brazil. RESULTS: Non-Hodgkin lymphomas represented 68% of the cases, including those of precursor (36% and mature (64% cell origin. Mature cell lymphomas comprised 81% of the B-cell phenotype and 19% of the T-cell phenotype. Hodgkin lymphomas represented 32% of all cases, including 87% of the classical type and 13% of nodular lymphocyte predominant type. The geographic distribution showed 38.4% of the cases in the Southeast region, 28.7% in the Northeast, 16.1% in the South, 8.8% in the North, and 8% in the Central-west region. The distribution by age groups was 15-18 years old, 33%; 11-14 years old, 26%; 6-10 years old, 24%; and 6 years old or younger, 17%. Among mature B-cell lymphomas, most of the cases were Burkitt lymphomas (65%, followed by diffuse large B-cell lymphomas (24%. In the mature T-cell group, anaplastic large cell lymphoma, ALK-positive was the most prevalent (57%, followed by peripheral T-cell lymphoma, then not otherwise specified (25%. In the group of classic Hodgkin lymphomas, the main histological subtype was nodular sclerosis (76%. Nodular lymphocyte predominance occurred more frequently than in other series. CONCLUSION: Some of the results found in this study may reflect the heterogeneous socioeconomical status and environmental factors of the Brazilian population in different regions.

  1. Mauritius - a Sustainable Island

    Larsen, Anders

    2010-01-01

    The Government of Mauritius has a long-term vision of transforming Mauritius into a sustainable Island. One important element towards the achievement of this vision is to increase the country's renewable energy usage and thereby reducing dependence on fossil fuels. Democratisation of energy...... production is determined to be the way forward. A step in this direction is to devolve upon citizens the ability and motivation to produce electricity via small-scale distributed generation (SSDG), i.e. wind, photovoltaic and hydro installations below 50 kW. Given that SSDG is more expensive per installed...... capacity than the existing much larger power plants, subsidies are needed so as to provide incentives to small independent power producers (SIPP), households and firms to invest in SSDG.The paper presents the context, the theoretical considerations and the proposed incentive schemes to enable electricity...

    Bacteria are highly diverse organisms that are able to adapt to a broad range of environments and hosts due to their high genomic plasticity. Horizontal gene transfer plays a pivotal role in this genome plasticity and in evolution by leaps through the incorporation of large blocks of genome sequences, ordinarily known as genomic islands (GEIs). GEIs may harbor genes encoding virulence, metabolism, antibiotic resistance and symbiosis-related functions, namely pathogenicity islands (PAIs), metabolic islands (MIs), resistance islands (RIs) and symbiotic islands (SIs). Although many software for the prediction of GEIs exist, they only focus on PAI prediction and present other limitations, such as complicated installation and inconvenient user interfaces. Here, we present GIPSy, the genomic island prediction software, a standalone and user-friendly software for the prediction of GEIs, built on our previously developed pathogenicity island prediction software (PIPS). We also present four application cases in which we crosslink data from literature to PAIs, MIs, RIs and SIs predicted by GIPSy. Briefly, GIPSy correctly predicted the following previously described GEIs: 13 PAIs larger than 30kb in Escherichia coli CFT073; 1 MI for Burkholderia pseudomallei K96243, which seems to be a miscellaneous island; 1 RI of Acinetobacter baumannii AYE, named AbaR1; and, 1 SI of Mesorhizobium loti MAFF303099 presenting a mosaic structure. GIPSy is the first life-style-specific genomic island prediction software to perform analyses of PAIs, MIs, RIs and SIs, opening a door for a better understanding of bacterial genome plasticity and the adaptation to new traits.

    Full Text Available Bamboo is one of the economic plant which grow widely in the villages and have been used by the local people in the villages. Indonesia has about 10% of the world bamboo, 50% among them was endemic to Indonesia. According Widjaja (2001 Lesser Sunda Island which consists of Lombok, Sumbawa, Flores, Timor, Sumba and other small island eastern of Flores has 14 bamboo species, however, the information from the Sumba Island was lacking because of lacking data from this area except one species which was proposed by S. Soenarko in 1977 where the type specimens was collected by Iboet 443 in 1925. To fullfill data from the Sumba Island, an exploration to this area has been conducted on July 2003. The observation was done in West Sumba and East Sumba District, especially in two natioal parks at both districts. According to this inventory study in the Sumba Island, there were 10 bamboo species in Sumba Island, 1 species among them (Dinochloa sp. was a new species which has not been collected before, whereas the other species (Dinochloa kostermansiana has a new addition record from this area. The bamboo species in Sumba Island were Bambusa blumeana, Bambusa vulgaris, Dendocalamus asper, Dinochloa kostermansiana, Dinochloa sp., Gigantochloa atter, Nastus reholtumianus, Phyllostachys aurea, Schisotachyum brachycladum and Schizostachyum lima. From 10 recorded species, the genera Dinochloa and Nastus grow wild in the forest, whereas another species grow widly or cultivated in the garden. Furthermore, the genus Dinochloa was the only genus grow climbing. The endemic species found in Sumba Island was Nastus reholttumianus, whereas Dinochloa kostermansiana was also found in Flores Island.

The Galápagos are perfectly situated for geophysical and geochemical investigations of deep-Earth processes at a hot spot, and proximity to a spreading center allows exploration of hot spot-ridge interactions. Several highly active volcanoes show rapid deformation facilitating investigation of melt transport paths and volcanic structure. The islands exhibit a range of ages, eruptive styles, and climatic zones that allow analysis of hydrogeologic and geomorphic processes. The Galápagos Islands are a World Heritage Site and are an ideal setting for developing an integrated biological and geological understanding of ocean island evolution.

  12. Neotectonics in northeastern Brazil

    Science.gov (United States)

    Bezerra, Francisco Hilario Rego

    The thesis describes neotectonic deformation in the continental intraplate region of northeastern Brazil and explores its links with modern seismicity. The region, which is under E-W-oriented compression and N-S-oriented extension, shows shallow earthquake swarms which last for several years and include 5.0-5.2 mb events. Remote sensing, borehole and geophysical data, in conjunction with field structural information, indicate a continuous faulting process since the Miocene which has reactivated Cretaceous faults and Precambrian shear zones or in places generated new faults which cut across existing structures. Three main sets of faults are recognised across the area: a NE-striking set, a NW-striking set and a N-striking set. The first and the second sets are pervasive and their cross-cutting relationships show that they locally form a conjugate set and display both a strike-slip and a dip-slip component of movement. They have generated troughs filled by as much as 260 m of Cainozoic sediments. Radiocarbon dating shows that some of the faults slipped as recently as 4,041-3,689 cal. yr BP. Although the elevation of coastal deposits is consistent with the predictions of glacioisostatic models for the area, tectonic influence can be detected notably near the Carnaubais fault, where rapid emergence by at least 5 m to the east of Sao Bento occurred 4,080-2,780 cal. yr BP. Secondary ground failure, which includes hydroplastic deformation, liquefaction and landslides, can be seen in Quaternary alluvial sediments and is reported in the historical record. The present data show that the potential for large earthquakes in northeastern Brazil has been underestimated. Empirical relationships using liquefaction and surface rupture point to events of at least Ms=6.8 compared to a maximum mb = 5.2 recorded instrumentally. The finding that NE- and NW-trending faults are favourably orientated for reactivation in relation to the current stress field is of potential value for seismic

    2016-10-01

    Landform changes in Ballast Island, a small coral reef island in the Ryukyu Islands, were investigated by remote sensing analysis and a field survey. The area of the island almost doubled after a mass coral bleaching event in 1998. Coral branches generated by the mass mortality and broken by waves were delivered and stocked on a reef flat and accumulated to expand the area of the island. In 2012 high waves generated by typhoons also changed the island's topography. Overall, the island moved in the downdrift direction of the higher waves. Waves impacting both sides of the island piled up a large volume of coral gravels above the high-tide level. Eco-geomorphic processes, including a supply of calcareous materials from the corals on the same reef especially during stormy wave conditions, were key factors in maintaining the dynamic topographic features of this small coral reef island.

    1999-03-01

    This article is an excerpted summary of a speech on female police and domestic violence. The speech was given by a woman affiliated with the Association of Women Workers at an Oxfam workshop in northern Brazil. This organization successfully lobbied for female police, which resulted in more reports of domestic violence, especially rape. The organization is active in 13 counties. Female police are trained and usually given respect by police chiefs. In one city, in 1997, the appointment of female police resulted in registered reports of 387 cases of violence and hospital reports of 503 cases, of which 14% were child rape. During January-April 1998, there were 126 registered cases and 168 hospital cases. Policewomen formed a partnership over the past 2 years with the Human Rights Group and other popular political groups to train female police about laws. The compulsory course focused on four areas: legal concepts, penalties, and procedures on registration of complaints; the Brazilian Penal Code; civil law; and world judicial bureaucracies. Training includes a 1 month internship with the program's lawyer. Over 20 women have completed the course to date. Training in some cases resulted in greater expertise among the female police than their Police Chiefs. Female police have experienced harassment by local authorities.

  18. Mammals evolve faster on smaller islands.

    Science.gov (United States)

    Millien, Virginie

    2011-07-01

    Island mammals often display remarkable evolutionary changes in size and morphology. Both theory and empirical data support the hypothesis that island mammals evolve at faster rates than their mainland congeners. It is also often assumed that the island effect is stronger and that evolution is faster on the smallest islands. I used a dataset assembled from the literature to test these assumptions for the first time. I show that mammals on smaller islands do indeed evolve more rapidly than mammals on larger islands, and also evolve by a greater amount. These results fit well the theory of an evolutionary burst due to the opening of new ecological opportunities on islands. This evolutionary burst is expected to be the strongest on the smallest islands where the contrast between the island and the mainland environments is the most dramatic.

    Simeonof Island is located south of the Alaska Peninsula in the hyperoceanic sector of the middle boreal subzone. We examined the bryoflora of Simeonof Island to determine species composition in an area where no previous collections had been reported. This field study was conducted in sites selected to represent the spectrum of environmental variation within Simeonof Island. Data were analyzed using published reports to compare bryophyte distribution patterns at three levels, the Northern Hemisphere, North America, and Alaska. A total of 271 bryophytes were identified: 202 mosses and 69 liverworts. The annotated list of species for Simeonof Island expands the known range for many species and fills distribution gaps within Hulte??n's Western Pacific Coast district. Maps and notes on the distribution of 14 significant distribution records are presented. Compared with bryophyte distribution in the Northern Hemisphere, the bryoflora of Simeonof Island primarily includes taxa of boreal (55%), temperate (20%), arctic (10%), and cosmopolitan (8%) distribution; 6% of the moss flora are western North America endemics. A description of the bryophytes present in the vegetation and habitat types is provided as is a quantitative analysis of the most frequently occurring bryophytes in crowberry heath.

    Deception Island is the most active volcano in the South Shetland Islands and has been the scene of more than twenty identified eruptions over the past two centuries. In this contribution we present the first comprehensive long-term volcanic hazard assessment for this volcanic island. The research is based on the use of probabilistic methods and statistical techniques to estimate volcanic susceptibility, eruption recurrence and the most likely future eruptive scenarios. We perform a statistical analysis of the time series of past eruptions and the spatial extent of their products, including lava flows, fallout, pyroclastic density currents and lahars. The Bayesian event tree statistical method HASSET is applied to calculate eruption recurrence, while the QVAST tool is used in an analysis of past activity to calculate the possibility that new vents will open (volcanic susceptibility). On the basis of these calculations, we identify a number of significant scenarios using the GIS-based VORIS 2.0.1 and LAHARZ software and evaluate the potential extent of the main volcanic hazards to be expected on the island. This study represents a step forward in the evaluation of volcanic hazard on Deception Island and the results obtained are potentially useful for long-term emergency planning.

    Full Text Available Despite its wide range and abundance on certain habitats, the crab-eating raccoon Procyon cancrivorus (G. Cuvier, 1798 is considered one of the less known Neotropical carnivore species. In the present study we analyzed the diet of P. cancrivorus in a peat forest and in an estuarine island in southernmost Brazil. Fruits of the gerivá palm tree Syagrus romanzoffiana were the most consumed item in the peat forest, followed by insects and mollusks. Small mammals, followed by Bromelia antiacantha (Bromeliaceae fruits and brachyuran crustaceans were the most frequent items in the estuarine island. Other items found in lower frequencies were Solanum sp., Psidium sp., Smilax sp. and Dyospiros sp. fruits, diplopods, scorpions, fishes, anuran amphibians, reptiles (black tegu lizard and snakes, birds and medium-sized mammals (white-eared opossum, armadillo and coypu. Levin’s index values (peat forest: 0.38; estuarine island: 0.45 indicate an approximation to a median position between a specialist and a well distributed diet. Pianka’s index (0.80 showed a considerable diet similarity between the two systems. Procyon cancrivorus presented a varied diet in the studied areas and may play an important role as seed disperser on coastal environments in southernmost Brazil.

    Full Text Available Sugar cane spirits are some of the most popular alcoholic beverages consumed in Cape Verde. The sugar cane spirit industry in Cape Verde is based mainly on archaic practices that operate without supervision and without efficient control of the production process. The objective of this work was to evaluate samples of industrial and alembic sugar cane spirits from Cape Verde and Ceará, Brazil using principal component analysis. Thirty-two samples of spirits were analyzed, twenty from regions of the islands of Cape Verde and twelve from Ceará, Brazil. Of the samples obtained from Ceará, Brazil seven are alembic and five are industrial spirits. The components analyzed in these studies included the following: volatile organic compounds (n-propanol, isobutanol, isoamylic, higher alcohols, alcoholic grade, acetaldehyde, acetic acid, acetate; copper; and sulfates.

    The Health in Prostitution Project was launched in 1991 in Rio de Janeiro, Brazil. The project offers a multi-year training program of health education designed to both fight the stigmatization of and violence against commercial sex workers and enhance their self-esteem, self-determination, and access to civil rights. The project therefore promotes individual awareness while influencing public opinion and policies. At first, health agents were recruited among women and transvestites who work in street-based sex work. The program was then gradually expanded to include young male sex workers and other locations, such as private parlors, saunas, and escort services. People of all sexes and sexual orientation now comprise the health agent group. The program has a paid staff of five women, three young men, and three transvestites, and approximately 70 sex workers are trained annually. Basic training includes topics such as human sexuality, personal risk assessment, HIV/STD infection, negotiation of safer sex, and STD referral services. Year two training emphasizes reproductive and women's health issues, while year three courses prioritize street work methodologies. Theatrical performances, speaking English as a second language, and performing Bach flower therapy for clients take place during the fourth year. Program trainers include medical specialists, nurses, psychologists, health educators, lawyers, and university students. At least half of the 350 health agents trained thus far are estimated to be currently engaged in paid or voluntary prevention work. Two surveys with female sex workers in 1991 and 1993 found that reported regular condom use increased from 57% to 73%; the health agents are having an effect. The program is constantly evaluated and revised.

    Zika virus (ZIKV) infection is spreading rapidly within the Americas after originating from an outbreak in Brazil. We describe the current ZIKV infection epidemic in Brazil and the neurological symptoms arising. First cases of an acute exanthematic disease were reported in Brazil's Northeast region at the end of 2014. In March 2015, autochthonous ZIKV was determined to be the causative agent of the exanthematic disease. As cases of neurological syndromes in regions where ZIKV, dengue and/or Chikungunya viruses co-circulate were reported, ZIKV was also identified in the cerebrospinal fluid of patients with acute neurological syndromes and previous exanthematic disease. By the end of September 2015, an increasing number of infants with small head circumference or microcephaly were noted in Brazil's Northeast which was estimated to be 29 cases between August and October. ZIKV was identified in blood and tissue samples of a newborn and in mothers who had given birth to infants with microcephaly and ophthalmological anomalies. In 2015, there were an estimated 440,000 - 1,300,000 Zika cases in Brazil. There have been 4,783 suspected cases of microcephaly, most of them in the Northeast of Brazil associated with 76 deaths. The Ministry of Health is intensifying control measures against the mosquito Aedes aegypti and implemented intensive surveillance actions. Further studies are needed to confirm the suspected association between ZIKV infection and microcephaly; to identify antiviral, immunotherapy, or prophylactic vaccine; to introduce diagnostic ELISA testing. Clinical and epidemiological studies must be performed to describe viral dynamics and expansion of the outbreak.

    Full text: In this work Radiocarbon Accelerator Mass Spectrometry (AMS) is used to study holocene changes of the Brazilian coastal environment. The region of study is the Pantano Sul Inlet (27 degrees 51.7 min S - 48 degrees 31.6 min W) at Santa Catarina Island, in the South of Brazil, where a sediment core was collected at 14 meters depth. Parameters such as total organic carbon (TOC), total nitrogen (TN), stable isotopes ({delta}{sup 13}C and {delta}{sup 15}N), metallic elements and granulometry were evaluated and related to the {sup 14}C chronology. These parameters were used as proxies to infer about temporal changes in this coastal environment so that processes related to marine productivity and continental erosion could be better understood. The vertical distribution of elements revealed significant changes in the contribution of continental and marine sources along time. Al, Fe, Mn, Zn and Cu concentrations increase from the base to the surface of the core. Both Zn and Cu, and also TOC and TN present peaks at 20 and 35 cm depth. Organic matter in the profile ranged from 2.17 % to 6.02 % and carbonate fraction ranged from 15.54 % to 49.23 %. Both carbonate and soil organic matter fractions were analyzed by {sup 14}C AMS. Samples were prepared at the Radiocarbon Laboratory at the Fluminense Federal University (L4C-UFF) in Brazil to be dated by AMS. Measurements are under way in the new {sup 14}C AMS facility at UFF (a 250 kV single-stage AMS system) and will be the first radiocarbon AMS study to be performed entirely in Brazil. (author)

  13. Late Quaternary climate change shapes island biodiversity.

    2016-04-07

    Island biogeographical models consider islands either as geologically static with biodiversity resulting from ecologically neutral immigration-extinction dynamics, or as geologically dynamic with biodiversity resulting from immigration-speciation-extinction dynamics influenced by changes in island characteristics over millions of years. Present climate and spatial arrangement of islands, however, are rather exceptional compared to most of the Late Quaternary, which is characterized by recurrent cooler and drier glacial periods. These climatic oscillations over short geological timescales strongly affected sea levels and caused massive changes in island area, isolation and connectivity, orders of magnitude faster than the geological processes of island formation, subsidence and erosion considered in island theory. Consequences of these oscillations for present biodiversity remain unassessed. Here we analyse the effects of present and Last Glacial Maximum (LGM) island area, isolation, elevation and climate on key components of angiosperm diversity on islands worldwide. We find that post-LGM changes in island characteristics, especially in area, have left a strong imprint on present diversity of endemic species. Specifically, the number and proportion of endemic species today is significantly higher on islands that were larger during the LGM. Native species richness, in turn, is mostly determined by present island characteristics. We conclude that an appreciation of Late Quaternary environmental change is essential to understand patterns of island endemism and its underlying evolutionary dynamics.

  17. The Big Island of Hawaii

    Science.gov (United States)

    2002-01-01

    Boasting snow-covered mountain peaks and tropical forest, the Island of Hawaii, the largest of the Hawaiian Islands, is stunning at any altitude. This false-color composite (processed to simulate true color) image of Hawaii was constructed from data gathered between 1999 and 2001 by the Enhanced Thematic Mapper plus (ETM+) instrument, flying aboard the Landsat 7 satellite. The Landsat data were processed by the National Oceanographic and Atmospheric Administration (NOAA) to develop a landcover map. This map will be used as a baseline to chart changes in land use on the islands. Types of change include the construction of resorts along the coastal areas, and the conversion of sugar plantations to other crop types. Hawaii was created by a 'hotspot' beneath the ocean floor. Hotspots form in areas where superheated magma in the Earth's mantle breaks through the Earth's crust. Over the course of millions of years, the Pacific Tectonic Plate has slowly moved over this hotspot to form the entire Hawaiian Island archipelago. The black areas on the island (in this scene) that resemble a pair of sun-baked palm fronds are hardened lava flows formed by the active Mauna Loa Volcano. Just to the north of Mauna Loa is the dormant grayish Mauna Kea Volcano, which hasn't erupted in an estimated 3,500 years. A thin greyish plume of smoke is visible near the island's southeastern shore, rising from Kilauea-the most active volcano on Earth. Heavy rainfall and fertile volcanic soil have given rise to Hawaii's lush tropical forests, which appear as solid dark green areas in the image. The light green, patchy areas near the coasts are likely sugar cane plantations, pineapple farms, and human settlements.

    The effects of the local dielectric environment on the surface-plasmon resonances of annealed gold-island films are studied experimentally and modeled theoretically. Gold- island films were annealed at 600 degree(s)C to produce spheroidal shape particles which exhibit well-resolved resonances in polarized, angle-resolved, absorption spectra. These resonances are shifted in different amounts by the depolarization effect of the surrounding medium (liquids with various refraction indices). Cross-section calculations based upon non-retarded, single-particle, dielectric interaction for these various configurations are presented and found to be in good agreement with the experimental observations.

  5. Streamlined Islands in Ares Valles

    Science.gov (United States)

    2002-01-01

    (Released 10 June 2002) The Science Although liquid water is not stable on the surface of Mars today, there is substantial geologic evidence that large quantities of water once flowed across the surface in the distant past. Streamlined islands, shown here, are one piece of evidence for this ancient water. The tremendous force of moving water, possibly from a catastrophic flood, carved these teardrop-shaped islands within a much larger channel called Ares Valles. The orientation of the islands can be used as an indicator of the direction the water flowed. The islands have a blunt end that is usually associated with an obstacle, commonly an impact crater. The crater is resistant to erosion and creates a geologic barrier around which the water must flow. As the water flows past the obstacle, its erosive power is directed outward, leaving the area in the lee of the obstacle relatively uneroded. However, some scientists have also argued that the area in the lee of the obstacle might be a depositional zone, where material is dropped out of the water as it briefly slows. The ridges observed on the high-standing terrain in the leeward parts of the islands may be benches carved into the rock that mark the height of the water at various times during the flood, or they might be indicative of layering in the leeward rock. As the water makes its way downstream, the interference of the water flow by the obstacle is reduced, and the water that was diverted around the obstacle rejoins itself at the narrow end of the island. Therefore, the direction of the water flow is parallel to the orientation of the island, and the narrow end of the island points downstream. In addition to the streamlined islands, the channel floor exhibits fluting that is also suggestive of flowing water. The flutes (also known as longitudinal grooves) are also parallel to the direction of flow, indicating that the water flow was turbulent and probably quite fast, which is consistent with the hypothesized

    1. The Antillean manatee (Trichechus manatus manatus), a subspecies of the West Indian manatee, is a large-bodied marine mammal found in fresh, brackish, and marine habitats throughout the Caribbean Islands and Central and South America. Antillean manatees in Brazil are classified as critically endangered, with a census size of approximately 500 individuals. The population in the Northeast region of Brazil is suspected to have approximately 300 manatees and is threatened by habitat alteration and incidental entanglement in fishing gear. 2. A high incidence of dependent calf strandings have been identified near areas of altered critical manatee habitat. The majority of the calves are neonates, discovered alive, with no potential mothers nearby. These calves typically require human intervention to survive.

    Zika virus (ZIKV) is now considered an emerging flavivirosis, with a first large outbreak registered in the Yap Islands in 2007. In 2013, a new outbreak was reported in the French Polynesia, with associated cases of neurological complications including Guillain-Barré syndrome (GBS). The incidence of GBS has increased in Brazil since 2015, what is speculated to be secondary to the ZIKV infection outbreak. The gold-standard test for detection of acute ZIKV infection is the polymerase-chain reaction technique, an essay largely unavailable in Brazil. The diagnosis of GBS is feasible even in resource-limited areas using the criteria proposed by the GBS Classification Group, which is based solely on clinical grounds. Further understanding on the relationship of ZIKV with neurological complications is a research urgency.

    Full Text Available We reviewed available information on seabirds inhabiting Easter Island, Salas y Gómez Island and Desventuradas Islands and their adjacent waters through an analysis of published and grey literature. Results obtained indicate that a total of 37 species are present in the study area and that, among the orders represented, the Procellariiformes and Charadriiformes are the dominant taxa (29 species. Moreover, the family Procellariidae is represented by 13 species and Laridae by 7 species. There has been an increase in new records over the past six years but no systematic studies have been developed. The need for further research that focuses on ecological aspects and anthropogenic impacts is critical in order to develop adequate conservation strategies.

    Full Text Available We compared the effects of habitat disturbance on the feeding ecology of two local populations of Tropidurus torquatus (Wied, 1820 in restinga habitats on Ilha da Marambaia, Southeastern Brazil. Both populations presented a relatively diverse diet and differ in the number (D Max = 0.22, DF = 2, p = 0.00 and volume of prey consumed (D Max = 0.82, DF = 2, p = 0.00. Ants were the most frequent and numerous preys in both areas, and plant matter and coleopterans were the most important alimentary items in volume. The population from the disturbed area presented a larger niche breadth for number of prey items consumed (Bi num = 3.06 and volume (Bi vol = 2.98, when compared to the other population (Bj num = 2.44, Bj vol = 1.52. Niche overlap was higher for number of items consumed between the populations (Oij num = 0.82 but lower for volume (Oij vol = 0.05. Our data suggest dietary differences between the two lizard populations, and these differences may be associated with environmental modifications. Our main hypothesis to explain the dietary differences is based in the Optimal Foraging Theory. However, the alimentary behavior, and consequently the diet of these lizards, seems to be constrained phylogenetically, with a pattern that may have evolved in the ancestor of all iguanids.Comparamos os efeitos da degradação ambiental sobre a ecologia alimentar de duas populações de Tropidurus torquatus (Wied, 1820 em áreas de restinga da Ilha da Marambaia, sudeste do Brasil.

    Full Text Available Abstract: Equine infectious anemia (EIA is a transmissible and incurable disease caused by a lentivirus, the equine infectious anemia virus (EIAV. There are no reports in the literature of this infection in Equidae on Marajo Island. The objective of this study was to diagnose the disease in the municipalities of Cachoeira do Arari, Salvaterra, Santa Cruz do Arari and Soure, on Marajó Island, state of Pará, Brazil. For serological survey samples were collected from 294 horses, over 5-month-old, males and females of puruca and marajoara breeds and from some half-breeds, which were tested by immunodiffusion in Agar gel (AGID. A prevalence of 46.26% (136/294 positive cases was found. EIA is considered endemic in the municipalities studied, due to the ecology of the region with a high numbered population of bloodsucking insect vectors and the absence of official measures for the control of the disease.

    Full Text Available Island studies tends to focus on peripheral, isolated, and marginal aspects of island communities, while urban studies has showed scant awareness of islandness: Although many people research cities on islands, there is little tradition of researching island cities or urban archipelagos per se. Island cities (densely populated small islands and population centres of larger islands and archipelagos nevertheless play import cultural, economic, political, and environmental roles on local, regional, and global scales. Many major cities and ports have developed on small islands, and even villages can fulfil important urban functions on lightly populated islands. Island concepts are also deployed to metaphorically describe developments in urban space. The journal Urban Island Studies explores island and urban processes around the world, taking an island approach to urban research and an urban approach to island research.

    Full Text Available The one-humped camel (Camelus dromedarius L. is not indigenous to the Canary Islands but based on historical references was introduced at the very beginning of the fifteenth century. The camel thrived in the subtropical dry environment. A long period of isolation from other animals of the same species meant that the animals were virtually disease free. This made the Islands an ideal base for exporting camels to new areas such that camels from the Canaries went to Peru in the sixteenth century, to Brazil in the eighteenth century, Venezuela and Bolivia in the early part of the nineteenth century and Australia in 1840. Camels went to several Caribbean islands in the middle of the nineteenth century. More recently (late twentieth and early twenty-first centuries some animals were exported from the islands to mainland Europe, notably France, Spain and the Netherlands, and to South America. Camels have been used in military operations, as transport and draught animals in support of agriculture and have found a role in the tourist industry. In early 2013 there were some 1,300 camels distributed over four of the larger islands of the archipelago in herds varying in size from a single animal to herds of as many as 150 head: a large group of about 400 heads kept in a Safari Park on the island of Fuerteventura is considered as the national conservation herd. The "Canary" camel has recently been shown to be genetically distinct from most other populations and it has been proposed that it should be designated as a distinct breed.

    Island environments share distinctive characteristics that offer unique opportunities to investigate parallel evolution. Previous research has produced evidence of an island syndrome for morphological traits, life-history strategies and ecological niches, but little is known about the response to insularity of other important traits such as animal signals. Here, we tested whether birds' plumage colouration is part of the island syndrome. We analysed with spectrophotometry the colouration of 116 species endemic to islands and their 116 closest mainland relatives. We found a pattern of reduced brightness and colour intensity for both sexes on islands. In addition, we found a decrease in the number of colour patches on islands that, in males, was associated with a decrease in the number of same-family sympatric species. These results demonstrate a worldwide pattern of parallel colour changes on islands and suggest that a relaxation of selection on species recognition may be one of the mechanisms involved.

In general, the more complex models performed badly. Average z-values were significantly lower for habitat island datasets than for true islands, and were higher for mountaintop and urban habitat islands than for other habitat island types. Average c-values were significantly...

  13. Inverter Anti-Islanding with Advanced Grid Support in Single- and Multi-Inverter Islands

    Energy Technology Data Exchange (ETDEWEB)

    Hoke, Andy

    2016-08-16

    As PV and other DER systems are connected to the grid at increased penetration levels, island detection may become more challenging for two reasons: 1. In islands containing many DERs, active inverter-based anti-islanding methods may have more difficulty detecting islands because each individual inverter's efforts to detect the island may be interfered with by the other inverters in the island. 2. The increasing numbers of DERs are leading to new requirements that DERs ride through grid disturbances and even actively try to regulate grid voltage and frequency back towards nominal operating conditions. These new grid support requirements may directly or indirectly interfere with anti-islanding controls. This report describes a series of tests designed to examine the impacts of both grid support functions and multi-inverter islands on anti-islanding effectiveness.

  3. Decentralization and REDD+ in Brazil

    Directory of Open Access Journals (Sweden)

    Fabiano Toni

    2011-01-01

    Full Text Available Recent discussions on REDD+ (Reducing Emissions from Deforestation and Forest Degradation, plus conservation, sustainable management of forests and enhancement of forest carbon stocks have raised optimism about reducing carbon emissions and deforestation in tropical countries. If approved under the United Nations Framework Convention on Climate Change (UNFCCC, REDD+ mechanisms may generate a substantial influx of financial resources to developing countries. Some authors argue that this money could reverse the ongoing process of decentralization of forest policies that has spread through a large number of developing countries in the past two decades. Central states will be accountable for REDD+ money, and may be compelled to control and keep a significant share of REDD+ funds. Supporters of decentralization argue that centralized implementation of REDD+ will be ineffective and inefficient. In this paper, I examine the relation between subnational governments and REDD+ in Brazil. Data show that some state governments in the Brazilian Amazon have played a key role in creating protected areas (PAs after 2003, which helped decrease deforestation rates. Governors have different stimuli for creating PAs. Some respond to the needs of their political constituency; others have expectations to boost the forest sector so as to increase fiscal revenues. Governors also have led the discussion on REDD+ in Brazil since 2008. Considering their interests and political power, REDD+ is unlikely to curb decentralization in Brazil.

  4. Introduced mammals on Western Indian Ocean islands

    Directory of Open Access Journals (Sweden)

    James C. Russell

    2016-04-01

    Full Text Available The diversity of introduced mammals and their introduction history varies greatly across the Western Indian Ocean (WIO islands, from ancient introductions in the past millennia on islands off the East coast of Africa where extant terrestrial native mammal communities exist, to very recent invasions in the past decades on islands in the Mascarene archipelago. We compile the distribution of 16 introduced mammal taxa on 28 island groups comprising almost 2000 islands. Through an exhaustive literature review and expert consultation process we recorded all mammal eradications, and species recoveries which could be attributed to introduced mammal eradication or control. All island groups have been invaded by mammals, and invasive cats and rats in particular are ubiquitous, but cultural contingency has also led to regional invasions by other mammals such as lemurs, civets and tenrecs. Mammal eradications have been attempted on 45 islands in the WIO, the majority in the Seychelles and Mauritius, and where successful have resulted in spectacular recovery of species and ecosystems. Invasive mammalian predator eradication or control in association with habitat management has led to improved conservation prospects for at least 24 species, and IUCN red-list down-listing of eight species, in the Mascarene Islands. Future island conservation prioritisation in the region will need to take account of global climate change and predicted sea-level rises and coastal inundation. Greater investment and prioritisation in island conservation in the region is warranted, given its high biodiversity values and the extent of invasions.

  5. Pathogenicity island mobility and gene content.

    Energy Technology Data Exchange (ETDEWEB)

    Williams, Kelly Porter

    2013-10-01

    Key goals towards national biosecurity include methods for analyzing pathogens, predicting their emergence, and developing countermeasures. These goals are served by studying bacterial genes that promote pathogenicity and the pathogenicity islands that mobilize them. Cyberinfrastructure promoting an island database advances this field and enables deeper bioinformatic analysis that may identify novel pathogenicity genes. New automated methods and rich visualizations were developed for identifying pathogenicity islands, based on the principle that islands occur sporadically among closely related strains. The chromosomally-ordered pan-genome organizes all genes from a clade of strains; gaps in this visualization indicate islands, and decorations of the gene matrix facilitate exploration of island gene functions. A %E2%80%9Clearned phyloblocks%E2%80%9D method was developed for automated island identification, that trains on the phylogenetic patterns of islands identified by other methods. Learned phyloblocks better defined termini of previously identified islands in multidrug-resistant Klebsiella pneumoniae ATCC BAA-2146, and found its only antibiotic resistance island.

  6. Island development: Local governance under globalization

    2014-12-01

    Full Text Available Issues surrounding island development have generated a growing volume of research. What does it mean to develop? How can island communities maintain control over development processes to the benefit of the local economy, rather than seeing economic flows enter and exit the island with little or a primarily negative impact? And how important is local knowledge for edifying local governance and enhancing potentials for innovation in island development? Island histories have repeatedly been forwarded as exemplars and ‘lessons’ for global learning on (unsustainability. To consider these issues, we have selected a number of papers from among the presentations given at the International Geographical Union’s Commission on Islands Conference, Island Development: Local Economy, Culture, Innovation and Sustainability, which took place in the Penghu Archipelago, Taiwan, 1–5 October 2013. These papers serve as examples of how the processes of globalization have penetrated the borders and changed the political and economic structures of islands. They also explore how island-based innovations in science, technology, culture, and formal or informal governance might contribute to sustainable island development.

    A. E. Scheidegger

    1998-06-01

    Full Text Available A study is made of the orientations (strikes/trends of joints, valleys, ridges and lineaments, i.e. of the (potentially morphotectonic features, of the Mascarene Islands (Reunion, Mauritius and Rodrigues in the Indian Ocean. It turns out that a connection exists between these features on all islands. For the joints alone, the results for Mauritius as a whole agree closely with those for Rodrigues as a whole, and also partially with those of Reunion. Inasmuch as the trends of the valleys, ridges and lineaments are related to the trends (strikes of the joints, a common morphotectonic predesign seems to be present for all features studied. The morphotectonic orientations on the island also agree closely with the trends of fracture zones, ridges and trenches in the nearby ocean bottom; which has had a bearing on the theories of the origin of the Mascarene Islands. Generally, a hot-spot origin is preferred for Reunion, and may be for Mauritius as well, although differing opinions have also been voiced. The dynamics of a hot-spot is hard to reconcile with the close fit of the joint strikes in Réunion with the trends of the Madagascar and Rodrigues fracture zones. The closely agreeing joint maxima in Mauritius and Rodrigues í across the deep Mauritius trench í also agree with the trend of that trench and with the trend of the Rodrigues fracture zone. Thus, it would appear as most likely that the trends of joints and of fracture zones are all part of the same pattern and are due to the same cause: viz. to action of the neotectonic stress field.

  9. Floating Cities, Islands and States

    CERN Document Server

    Bolonkin, Alexander

    2008-01-01

    Many small countries are in need of additional territory. They build landfills and expensive artificial islands. The ocean covers 71 per cent of the Earth surface. Those countries (or persons of wealth) starting the early colonization of the ocean may obtain advantages through additional territory or creating their own independent state. An old idea is building a big ship. The best solution to this problem, however, is the provision of floating cities, islands, and states. The author idea is to use for floating cities, islands, and states a cheap floating platform created from a natural ice field taken from the Arctic or Antarctic oceans. These cheap platforms protected by air-film (bottom and sides) and a conventional insulating cover (top) and having a cooling system can exist for an unlimited time. They can be increased in number or size at any time, float in warm oceans, travel to different continents and countries, serve as artificial airports, harbors and other marine improvements, as well as floating c...

  10. Generalized model of island biodiversity

    Kessler, David A.; Shnerb, Nadav M.

    2015-04-01

    The dynamics of a local community of competing species with weak immigration from a static regional pool is studied. Implementing the generalized competitive Lotka-Volterra model with demographic noise, a rich dynamics with four qualitatively distinct phases is unfolded. When the overall interspecies competition is weak, the island species recapitulate the mainland species. For higher values of the competition parameter, the system still admits an equilibrium community, but now some of the mainland species are absent on the island. Further increase in competition leads to an intermittent "disordered" phase, where the dynamics is controlled by invadable combinations of species and the turnover rate is governed by the migration. Finally, the strong competition phase is glasslike, dominated by uninvadable states and noise-induced transitions. Our model contains, as a special case, the celebrated neutral island theories of Wilson-MacArthur and Hubbell. Moreover, we show that slight deviations from perfect neutrality may lead to each of the phases, as the Hubbell point appears to be quadracritical.

  11. Occurrence and distribution of the exotic lizard Hemidactylus mabouia Moreau de Jonnès, 1818 in Ilha Grande, RJ, Brazil

    Directory of Open Access Journals (Sweden)

    CFD Rocha

    Full Text Available The gekkonid lizard Hemidactylus mabouia is an exotic species in Brazil and is found in different ecosystems. This species was recorded at Ilha Grande, RJ, one of the largest insular remains of the Atlantic Rainforest in Brazil. In this study, the occurrence of H. mabouia was determined throughout the island, including the rain forest, restinga and anthropic environments. We used the active search method in points along 19 trails that surround Ilha Grande. At each regular interval of 100 m, we searched for the presence of H. mabouia. The species was recorded in a total of 100 points among the 719 sampled and, in all cases, the occurrence of the lizard corresponded to points located in anthropic or perianthropic areas. As most of Ilha Grande is covered by dense tropical rain forest, we believe this has restricted the invasion of H. mabouia in natural environments within the island.

    Surveys were conducted on three traffic-less islands: Tory and Aran, off the coast of Ireland, and Sark, one of the Channel Islands off the coast of France. Identical methods were used in surveys in three other areas, all of which have heavy gasoline driven traffic. These were Jersey, another of the Channel Islands, Ebbw Vale--a mixed industrial area, and Cardiff--the capital city of Wales. Environmental lead levels were very low in two of the traffic-less islands, but on the third, house dust lead levels were comparable with levels found throughout Wales. Blood lead levels on one of the islands were similar to those which have been reported for unaccultured remote tribes, but on the other two traffic-less islands blood lead levels were comparable with those of areas on the mainland of Wales.

    Dag Anckar

    2006-05-01

    Full Text Available In order to explicate the relevance of the island dimension for political categories, for each of seven political institutions, a series of four comparisons are conducted on a global basis. The first is between small island states and all other states, the second is between small island states and larger island states, the third is between small island states and small mainland states, and the fourth is between island states and mainland states, regardless of size. The finding is that islandness links in many instances to the choice of institutional settings. Political scientists are therefore well-advised to include in their analyses islandness among the factors that shape institutional choices.

    The 1973 energy crisis prompted the United States to suspend supplies of enriched uranium to the reactor being built in Brazil, Angra I. In 1975, the Brazil-Germany Nuclear Agreement was announced. The Programme was a failure. Today the Angra II nuclear reactor has been completed, the only reactor completed under the agreement with Germany. Brazil's last military President implemented the Parallel Nuclear Programme, which included uranium enrichment with the justification of developing the technology that had not been transferred through the Nuclear Agreement with Germany. In 1986, the existence of a deep shaft drilled by the Air Force was revealed. A Technical Report concluded that it had all the characteristics and dimensions required to test a nuclear bomb. Some years later, the Civilian Government acknowledged the existence of an underground nuclear explosion facility and symbolically sealed this shaft. The situation in Brazil has improved recently. Brazil ratified the Treaty of Tlatelolco on the denuclearisation of Latin America and established ABACC, an agency handling mutual inspections of nuclear facilities in Brazil and Argentina. Brazil also signed the Nuclear Weapons Non-Proliferation Treaty. The uranium enrichment activities are being transferred to a civilian industry. More importantly, I do not believe that the uranium enrichment project is intended to endow Brazil with the capacity to produce nuclear weapons. (author)

    We report on the observation and study of tree-ring structures below dislocated SiGe islands (superdomes) grown on Si(001) substrates. Analogous to the study of tree rings (dendrochronology), these footprints enable us to gain unambiguous information on the growth and evolution of superdomes and their neighboring islands. The temperature dependence of the critical volume for dislocation introduction is measured and related to the composition of the islands. We show clearly that island coalescence is the dominant pathway towards dislocation nucleation at low temperatures, while at higher temperatures anomalous coarsening is effective and leads to the formation of a depletion region around superdomes.

    Brazil is a large country with a wide diversity of landscapes and geological features and has been an important world producer of mineral resources. Despite this, until the 90's of last century, there has not been much concern and policies about geological heritage and geoconservation. Only at the end of the century the National Geological Service (CPRM) included the physical characterization of areas with geotouristic interest in its mission of generation and diffusion of geological information. In 1997, was created the Brazilian Commission of Geological and Paleobiological Sites (SIGEP, http://sigep.cprm.gov.br), responsible for the assessment, description and publicizing the sites of geological heritage. This is by now the most comprehensive and relevant initiative to protect the national heritage. It is composed by a fully accessible national database composed by 167 certified sites presented as scientific papers. Furthermore, a web-based applicative for the inventory and protection of geological heritage sites is being developed by the National Geological Service. The wider knowledge about geological heritage can be a useful tool for its conservation and this has been an important goal in the creation of protected areas, by means of environmental education and tourism. In Brazil, actions, research and publications about the subject have increased in the last five years, as well as the outreach and responsible use of the geological heritage. Scientific meetings, conferences and courses are growing and spreading around the country. The main scientific meeting has been the Brazilian Symposium of Geological Heritage that in its second edition (2013) had more than 200 papers presented. At that meeting it was also created the Association in Defence of the Geomining Heritage and the Association of Aspiring Geoparks. Brazil has only one geopark in the Unesco's Global Geopark Network, that is the Araripe Geopark, created in 2006. By the moment, propositions are being

    Fernando de Noronha is an archipelago of 21 islands and islets in the Atlantic Ocean, state of Pernambuco, Brazil, which has a varied biodiversity including alien species or sinantropic animals. The objective here was to determine the seroprevalence of Toxoplasma gondii in domestic and wild animals from Fernando de Noronha archipelago, Brazil. Between July 2007 and May 2010, blood samples were collected from 764 animals (533 domestic and 231 wild animals). Sera were tested by the indirect fluorescence antibody test (IFAT) or the modified agglutination test (MAT), or by both. Antibodies to T. gondii were found in 80 (80.0%) of 100 chickens ( Gallus domesticus ), 3 (3.0%) of 100 cattle ( Bos taurus ), 59 (60.8%) of 97 sheep ( Ovis aries ), 9 (81.8%) of 11 goats ( Capra hircus ), 7 (43.7%) of 16 horses ( Equus caballus ), 70 (59.3%) of 118 cats ( Felis catus ), 36 (39.6%) of 91 dogs ( Canis familiaris ), 13 (38.2%) of 34 black rats ( Rattus rattus ), and 157 (79.7%) of 197 cattle egrets ( Bubulcus ibis ). Results indicate endemic infection by this zoonotic parasite among the animal and avian fauna in this archipelago from Brazil.

    Plant communities of Unalaska Island in the eastern Aleutian Islands of western Alaska, and their relationship to environmental variables, were studied using a combined Braun-Blanquet and multivariate approach. Seventy relevés represented the range of structural and compositional variation in the matrix of vegetation and landform zonation. Eleven major community types were distinguished within six physiognomic–ecological groups: I. Dry coastal meadows: Honckenya peploides beach meadow, Leymus mollis dune meadow. II. Mesic meadows: Athyrium filix-femina – Aconitum maximum meadow, Athyrium filix-femina – Calamagrostis nutkaensis meadow, Erigeron peregrinus – Thelypteris quelpaertensis meadow. III. Wet snowbed meadow: Carex nigricans snowbed meadow. IV. Heath: Linnaea borealis – Empetrum nigrum heath, Phyllodoce aleutica heath, Vaccinium uliginosum – Thamnolia vermicularis fellfield. V. Mire: Carex pluriflora – Plantago macrocarpa mire. VI. Deciduous shrub thicket: Salix barclayi – Athyrium filix-femina thicket. These were interpreted as a complex gradient primarily influenced by soil moisture, elevation, and pH. Phytogeographical and syntaxonomical analysis of the plant communities indicated that the dry coastal meadows, most of the heaths, and the mire vegetation belonged, respectively, to the widespread classes Honckenyo–Elymetea, Loiseleurio–Vaccinietea, and Scheuchzerio–Caricetea, characterized by their circumpolar and widespread species. Amphi-Beringian species were likely diagnostic of amphi-Beringian syntaxa, many of these yet to be described.

  3. In or On? Island Words, Island Worlds: II

    Directory of Open Access Journals (Sweden)

    Ronstrom Owe

    2011-11-01

    Full Text Available The first part of the paper examines uses and meanings of the orientational metaphors ‘in’, ‘on’, ‘out’ and ‘off’. In the discussed languages in North Western Europe there are general principles of metaphoric entailment and underlying image schemas that guide the choice of positional metaphor: islands you are normally ‘on’, and mainlands ‘in’. The second part of the paper examines cases where this use is debated or contested. The author finds that these contestations seem to be fuelled by the different relations between subject and object that positional metaphors entail. Expressions with ‘in’ highlight belonging and collective identity, enlarge objects by conceptualizing them as encompassing containers, and reduce subjects to a part of the object. Expressions with ‘on’ highlight individuality and agency, reduce the object, and enlarge the subject by placing it above the object. Such differing entailments of positional metaphors may influence how islands are positioned and understood.

    The rising concerns about global warming and energy security have spurred a revival of interest in nuclear energy, giving birth to a 'nuclear power renaissance' in several countries in the world. Particularly in Brazil, in the recent years, the nuclear power renaissance can be seen in the actions that comprise its nuclear program, summarily the increase of the investments in nuclear research institutes and the government target to design and build the Brazilian Multipurpose research Reactor (BMR). In the last 50 years, Brazilian research reactors have been used for training, for producing radioisotopes to meet demands in industry and nuclear medicine, for miscellaneous irradiation services and for academic research. Moreover, the research reactors are used as laboratories to develop technologies in power reactors, which are evaluated today at around 450 worldwide. In this application, those reactors become more viable in relation to power reactors by the lowest cost, by the operation at low temperatures and, furthermore, by lower demand for nuclear fuel. In Brazil, four research reactors were installed: the IEA-R1 and the MB-01 reactors, both at the Instituto de Pesquisas Energeticas Nucleares (IPEN, Sao Paulo); the Argonauta, at the Instituto de Engenharia Nuclear (IEN, Rio de Janeiro) and the IPR-R1 TRIGA reactor, at the Centro de Desenvolvimento da Tecnologia Nuclear (CDTN, Belo Horizonte). The present paper intends to enumerate the characteristics of these reactors, their utilization and current academic research. Therefore, through this paper, we intend to collaborate on the BMR project. (author)

    Cunha Neves, A

    1980-01-01

    This paper discusses the social, political and cultural status of women in Brazil. In 1976 only 29.6% of Brazilian women participated in economic activities; 54.3% of these were still employed as laborers in the countryside, while only 6% were employed in urban and industrial jobs. The greatest concentration of female labor is in the category of the very badly paid domestic employment. Man is traditionally the head of the family, even when he is not the breadwinner. Illiteracy has decreased in Brazil to 24.3%, but female analphabetism is 26.5% versus 21.9% male analphabetism. Schools are open to males and females at all levels, but the traditional and cultural structure of Brazilian society considers the home, not the school, as the only proper place for young girls, and maternity is still the primary social function of women. Politically Brazilian women have very little power, even if they make up 44% of the electoral body. Sex education does not exist in the school or in the home, and any sexuality exercised outside the bonds of marriage is considered as deviant.

  9. Homosexuality and adoption in Brazil.

    2001-11-01

    Western societies are undergoing legal and policy changes in relation to laws governing the family, marital status, sexual orientation and the welfare of children, including in Brazil where, in the 1990s, the rights of homosexuals were incorporated into ongoing debates about what constitutes a family. This paper discusses the issue of adoption of children by homosexual men in Brazil, using information from court records from 1995-2000 in Rio de Janeiro, and from interviews with two judges, five psychologists and four social workers who evaluate those wishing to adopt. It uses the case records of one man's application to adopt, in which homosexuality became a central issue. Both the construction of masculinity in relation to parenting and concepts of the family were the parameters upon which the decision to allow him to adopt or not depended. Because the legislation does not specify what the sexual orientation of would-be adoptive parents should be, it is possible for single persons to adopt if they show they can be good parents. As more single people, alone or in couples, seek to adopt, it is important to clarify the criteria for judicial decisions on adoption applications. A dialogue is therefore needed on the meaning of family and whether and how it relates to sexual orientation. It is only on this basis that the courts can take a clear decision as to whether being homosexual is a relevant issue in regard to applications to adopt or not.

  11. Climate change and size evolution in an island rodent species: new perspectives on the island rule.

    2004-06-01

    As stated by the island rule, small mammals evolve toward gigantism on islands. In addition they are known to evolve faster than their mainland counterparts. Body size in island mammals may also be influenced by geographical climatic gradients or climatic change through time. We tested the relative effects of climate change and isolation on the size of the Japanese rodent Apodemus speciosus and calculated evolutionary rates of body size change since the last glacial maximum (LGM). Currently A. speciosus populations conform both to Bergmann's rule, with an increase in body size with latitude, and to the island rule, with larger body sizes on small islands. We also found that fossil representatives of A. speciosus are larger than their extant relatives. Our estimated evolutionary rates since the LGM show that body size evolution on the smaller islands has been less than half as rapid as on Honshu, the mainland-type large island of Japan. We conclude that island populations exhibit larger body sizes today not because they have evolved toward gigantism, but because their evolution toward a smaller size, due to climate warming since the LGM, has been decelerated by the island effect. These combined results suggest that evolution in Quaternary island small mammals may not have been as fast as expected by the island effect because of the counteracting effect of climate change during this period.

    2012-10-01

    Water supply is a major problem in the Adriatic islands, especially during the summer tourism season, and represents a limiting factor to the islands' further economic development. Much attention has been given to water supply solutions, primarily in terms of attempting to use the existing island water. Unfortunately, few islands have favourable hydrological conditions to accumulate significant quantities of surface water or groundwater. In the period from 2001 to 2004, investigations were conducted on many islands to define their own freshwater or partially brackish water resources since desalinisation technology could resolve a significant part of the water supply demand on small and distant islands. Due to the specificity and complexity of research in karst areas, the study was conducted in phases and included the geological and hydrogeological reconnaissance of the island, aimed at locating possible areas on the island where the necessary quantities of groundwater of adequate quality could be captured; a detailed hydrogeological mapping of the specified areas, geophysical investigation and test drilling; and, over several days, test pumping of the most promising borehole. One of the islands investigated was the island of Olib. The conducted surveys indicated that it is possible to pump about 3.5 L/s of groundwater from the karst aquifer of the island of Olib, which fully complies with the sanitary quality of drinking water.

  5. Genomic island excisions in Bordetella petrii

    Directory of Open Access Journals (Sweden)

    Levillain Erwan

    2009-07-01

    Full Text Available Abstract Background Among the members of the genus Bordetella B. petrii is unique, since it is the only species isolated from the environment, while the pathogenic Bordetellae are obligately associated with host organisms. Another feature distinguishing B. petrii from the other sequenced Bordetellae is the presence of a large number of mobile genetic elements including several large genomic regions with typical characteristics of genomic islands collectively known as integrative and conjugative elements (ICEs. These elements mainly encode accessory metabolic factors enabling this bacterium to grow on a large repertoire of aromatic compounds. Results During in vitro culture of Bordetella petrii colony variants appear frequently. We show that this variability can be attributed to the presence of a large number of metastable mobile genetic elements on its chromosome. In fact, the genome sequence of B. petrii revealed the presence of at least seven large genomic islands mostly encoding accessory metabolic functions involved in the degradation of aromatic compounds and detoxification of heavy metals. Four of these islands (termed GI1 to GI3 and GI6 are highly related to ICEclc of Pseudomonas knackmussii sp. strain B13. Here we present first data about the molecular characterization of these islands. We defined the exact borders of each island and we show that during standard culture of the bacteria these islands get excised from the chromosome. For all but one of these islands (GI5 we could detect circular intermediates. For the clc-like elements GI1 to GI3 of B. petrii we provide evidence that tandem insertion of these islands which all encode highly related integrases and attachment sites may also lead to incorporation of genomic DNA which originally was not part of the island and to the formation of huge composite islands. By integration of a tetracycline resistance cassette into GI3 we found this island to be rather unstable and to be lost from

    Brazil is the 10th largest energy consumer in the world and the third largest in the Western Hemisphere, behind the United States and Canada. Total primary energy consumption in Brazil has increased significantly in recent years; and over the past decade, Brazil has made great strides in increasing its total energy production, particularly oil. Brazil has the second-largest crude oil reserves in South America (behind Venezuela), and is one of the fastest growing oil producers in the world. According to United States Energy Information Administration (EIA), Brazil had 12.2 billion barrels of proven oil reserves in 2008. In 2007, Brazil's state owned Petroleo Brasileiro S.A. (PETROBRAS) announced that it had discovered an estimated 5-8 billion barrels of recoverable reserves (including both oil and natural gas) in the Tupi field, located in the Santos Basin. In 2008, subsequent discoveries were announced, to include Jupiter and Carioca (aka Sugar Loaf). Although PETROBRAS has yet to confirm the size of the discoveries, some industry analysts estimate the total extent of recoverable oil and natural gas reserves in the entire pre-salt layer have approached 40 to 80 billion barrels of oil equivalent. The reserves occur below a salt zone that is estimated to be 7,000 meters below the ocean surface. However, Brazil faces many challenges to recover the hydrocarbons to include technical, political, fiscal, and infrastructure hurdles. In spite of the challenges ahead, these discoveries transformed the nature and focus of Brazil's oil industry, economy, and future; and the potential impact of the pre-salt discoveries upon world oil markets is vast. The purpose of this paper is to discuss how the recent discoveries will affect Brazil's future and the impact it will have on the global energy world. (author)

    The Cape Verde Islands are of volcanic origin with most having appeared between the early Miocene and mid-Pleistocene. They contain six known species of Mabuya skinks. Phylogeographical relationships within and among the relatively widespread taxa M. stangeri, M. spinalis and M. delalandii were inferred, based on approximately 1 kbp of the cytochrome b gene (mitochondrial DNA). Reciprocal monophyly of M. spinalis and M. stangeri was established, which may have arisen from an early Pliocene/late Miocene cladogenetic event. Considerable between-island sequence divergence was detected among M. spinalis, which appears to have colonized the older islands (Sal and Boavista) first. Much lower sequence divergence was found in M. delalandii, indicating a more recent range expansion. Here, evidence points to colonization of the younger islands of Brava and Fogo soon after appearance. There are similarities between some of the described patterns and those seen in lizards from the Canary Islands.

    Growth of two-dimensional superstructure and island morphologies of silver atoms evaporated on a nickel (100) surface are studied by scanning tunneling microscopy. Near-equilibrium islands form at moderate annealing temperature (lower than 500 K) and present two kinds of morphologies. While they share a common monolayer c(2×8) superstructure, two distinct populations of islands coexist: rounded islands grown on the surface and spindle-shaped islands grown inside the Ni surface. The latter present a clear saturation of their density with increasing coverage. These shapes are mostly dominated by boundary energies as confirmed by a simple two-dimensional Wulff model whose parameters are derived using molecular statics simulations. Further annealing to 700 K leads to long Ag strips decorating the Ni step edges.

    The refractive index sensitivity of localized surface plasmon resonance sensors can be improved by placing the plasmonic metal particles on pillars instead of on a planar substrate. In this paper, a simple and versatile colloidal lithography method for the fabrication of plasmonic Au islands on top of polymer nanopillars is described. The pillar height is controlled by varying the thickness of the initial polymer film. An increased pillar height results in a blue shift of the absorption spectrum of the Au islands. This is explained by a decreased effective refractive index around the islands. For pillars higher than approximately 40 nm no further blue shift is observed, in agreement with the decay length of the electromagnetic field around the islands. Pillar-supported Au islands were also fabricated on a flexible foil, demonstrating the potential of the method described here for the fabrication of flexible plasmonic substrates. Benefits and limitations of the method and of using polymers as the pillar material are discussed.

    Full Text Available Land use and changes in land cover play an important role in local and regional climatic conditions, especially in tropical regions. Piracicaba, a city in southeastern Brazil, has an economy that is based primarily on sugar cane cultivation. The seasonality of this crop means that there are marked annual fluctuations in land use and cover in this municipality. In this work, we investigated the seasonal variation in urban heat-islands and local climatic variations by using remote sensing data, geographic information system (GIS and atmospheric modeling. The urban heat-islands were analyzed by using Landsat 7 (Enhanced Thematic Mapper+ images for the sugar cane crop (January to March and non-crop (August to November periods, and these images were subsequently converted to land surface brightness temperature. The average temperature in the non-crop period was 3.5°C higher than in the crop period, which suggested that heat-island intensity may be linked to the seasonality of sugar cane cultivation. In order to examine the influence of urban areas on regional temperature changes and heat fluxes, numerical simulations were done with the Brazilian Regional Atmospheric Modeling System (BRAMS. Overall, the results obtained suggested that local and regional climatic dynamics were related to land use and changes in land cover.

    In the last decades, wind power generation has proven its suitability to the Gigawatt scale, necessary to an effective contribution to electric systems. This paper demonstrates, from existing data, the wind / hydro seasonal complementarity in the relevant areas of Brazil, and discusses its possible effect on the feasibility of seasonal stabilization of the energy supply in the Brazilian interconnected grid, taking advantage of the country's large natural resources available. Case studies for the southern/southeastern and the northeastern regions of Brazil are presented. A brief analysis is included regarding the geographic location of the interconnected grid, main hydro power plants, and estimated promising wind farm areas in Brazil. (orig.)

    The annual meetings, organized by the Brazilian materials research society - B-MRS, are amongst the most import discussion forums in the area of materials science and engineering in Brazil, with a growing interest from the national and international scientific society. In the last 4 years, more than 1,500 participants have attended the B-MRS meetings, promoting an auspicious environment for presentation and discussion of scientific and technological works in the materials science area. The XIII Brazilian Materials Research Society Meeting was held from 28 September to 02 October, 2014, in João Pessoa, PB, Brazil. The Meeting congregated more than 1650 participants from the whole of Brazil and from 28 other countries. More than 2100 abstracts were accepted for presentation, distributed along 19 Symposia following the format used in traditional meetings of Materials Research Societies. These involved topics such as: synthesis of new materials, computer simulations, optical, magnetic and electronic properties, traditional materials as clays and cements, advanced metals, carbon and graphene nanostructures, nanomaterials for nanostructures, energy storage systems, composites, surface engineering and others. A novelty was a symposium dedicated to innovation and technology transfer in materials research. The program also included 7 Plenary Lectures presented by internationally renowned researchers: Alberto Salleo from Stanford University, United States of America; Roberto Dovesi from Universita' degli Studi di Torino, Italy; Luís Antonio F.

    Full Text Available There are few records of invertebrates mimicry by reptiles. In the Cerrados of central Brazil, the small Coleodactylus brachystoma is an endemic species common in the islands and margins of the Serra da Mesa hydroelectric dam reservoir. When cornered, this lizard folds the tail over the body exposing the pale-orange ventral surface. Lizard behavior, tail length and color pattern confer to this lizard a strong resemblance with syntopic buthid scorpions Rhopalurus agamenon, Tytius matogrossensis, and Anantheris balzani. Lizards and scorpions share the same tail color, size, and shape. Ecologically, they use the same microhabitats, are exposed to the same potential predators, and present similar behaviors when threatened.

    Chikungunya is an emerging arbovirus that is characterized into four lineages. One of these, the Asian genotype, has spread rapidly in the Americas after its introduction in the Saint Martin island in October 2013. Unexpectedly, a new lineage, the East-Central-South African genotype, was introduced from Angola in the end of May 2014 in Feira de Santana (FSA), the second largest city in Bahia state, Brazil, where over 5,500 cases have now been reported. Number weekly cases of clinically confirmed CHIKV in FSA were analysed alongside with urban district of residence of CHIKV cases reported between June 2014 and October collected from the municipality's surveillance network. The number of cases per week from June 2014 until September 2015 reveals two distinct transmission waves. The first wave ignited in June and transmission ceased by December 2014. However, a second transmission wave started in January and peaked in May 2015, 8 months after the first wave peak, and this time in phase with Dengue virus and Zika virus transmission, which ceased when minimum temperature dropped to approximately 15°C. We find that shorter travelling times from the district where the outbreak first emerged to other urban districts of FSA were strongly associated with incidence in each district in 2014 (R(2)).

    Full Text Available Hepatitis B virus genotype A1 (HBV/A1, of African origin, is the most prevalent genotype in Brazil, while HBV/F predominates in the other South American countries. However, HBV/D is the most common in the three states of southern Brazil, where 'islands' of elevated prevalence, as Chapecó and other cities, have been described. In this study, 202 HBV chronic carriers attending in 2013 the viral hepatitis ambulatory of Chapecó, were investigated. In comparison with previous studies performed in the same ambulatory, a rapid aging of the HBV infected population was observed (mean age of the newly diagnosed patients increasing from 29.9 ± 10.3 years in 1996 to 44.4 ± 13.3 years in 2013, probably due to a singular vaccination schedule at Chapecó that included not only children but also adolescents. Phylogenetic and BLAST analyses (S region classified 91 HBV isolates into genotypes A (n = 3 and D (n = 88. The majority of HBV/D isolates were closely related to D3 sequences. To understand the reasons for the absence or near absence of genotypes A and F, and how HBV/D was introduced in the south of Brazil, HBV/D infected patients were inquired about their genealogical and geographical origins. Forty-three (52% patients have their four grandparents of Italian origin, vs. seven (8% who have their four grandparents of Brazilian origin. At all, 65 out of 83 (78% patients had at least one grandparent originating from Italy. Taking into consideration the fact that Italy is one of the few countries where subgenotype D3 is predominant, the results strongly suggested that HBV/D was introduced in Brazil through Italian immigration which culminated between 1870 and 1920.

    Full Text Available Since the end of the 1990s, Brazil has succeeded in implementing and developing an economic model based on an inflation target model to keep domestic prices under control, a flexible exchange rate and a commitment to ensuring the solvency of the public sector. This model was initially adopted during Fernando Henrique Cardoso’s second term as president, and subsequently maintained and refined during Luis Inácio Lula da Silva’s two terms. Its development will certainly continue under the presidency of Dilma Rousseff. The consensus on this economic model and the relative dissociation of political and economic cycles have facilitated the stabilisation of the domestic environment and the acceleration of economic growth.

    2014-02-01

    Full Text Available The taeniasis-cysticercosis complex is a long known zoonotic parasitosis characteristic of underdeveloped countries. In addition to its public health significance, this parasitosis is cause of economic losses to the beef production chain, and synonymous of technical inadequacy in relation to the adoption of Good Agricultural Practices. The occurrences of both human teniasis and bovine cysticercosis could and should be controlled with basic sanitary measures. However, there is much variation in the occurrence of the disease in cattle, characterizing a low rate of technical development as well as problems related to the adoption of basic sanitation measures. This review describes, in details, the causative agent and its epidemiological chain, besides raising current information about the occurrence of bovine cysticercosis in different regions of Brazil, aiming at the adoption of prophylactic measures by different segments responsible.

    1999-12-01

    A fiber optic chemical sensor based on gold-island surface plasmon excitation is presented. The sensing part of the fiber is the end of the fiber onto which a thin layer of gold has been deposited to form a particulate surface. Annealing the gold reshapes the particles and produces an optical absorbance near 535 nm with the fiber in air. The optical absorption resonance of the gold particles is shifted if the fiber is immersed in a medium other than air. These resonance shifts are examined by transmission spectroscopy through the fiber. Experimental results for the sensitivity and dynamic range in the measurement of liquid solutions are in agreement with a basic theoretical model which characterizes the surface plasmon using nonretarded electrodynamics.

    The Yap Islands consist of four major islands, Yap, Gagil-Tamil, Maap, and Rumung. Of these, Yap Island has more than half the total land area, most of the population, and almost all of the economic development. The islands of Maap and Rumung together compose only 15 percent of the land area and population. Average annual rainfall over the Yap Islands amounts to 122 inches. Rainfall-runoff comparisons indicate that about half of the annual rainfall runs off to the ocean on Yap Island and Gagil-Tamil. Streams on Gagil-Tamil are perennial but streams on Yap Island are dry an average of 3 months per year due to geologic differences. Analyses of water samples from 23 sources show the good quality and the chemical similarity of surface and ground water. This report summarizes the hydrologic data collected and provides interpretations that can be used by the planning and public works officials of Yap to make decisions concerning development and management of their water resources.

    This 1997 special sampling project represents a special radiobiological sampling effort to augment the 1996 Long-Term Hydrological Monitoring Program (LTHMP) for Amchitka Island in Alaska. Lying in the western portion of the Aleutian Islands arc, near the International Date Line, Amchitka Island is one of the southernmost islands of the Rat Island Chain. Between 1965 and 1971, the U.S. Atomic Energy Commission conducted three underground nuclear tests on Amchitka Island. In 1996, Greenpeace collected biota samples and speculated that several long-lived, man-made radionuclides detected (i.e., americium-241, plutonium-239 and -240, beryllium-7, and cesium-137) leaked into the surface environment from underground cavities created during the testing. The nuclides of interest are detected at extremely low concentrations throughout the environment. The objectives of this special sampling project were to scientifically refute the Greenpeace conclusions that the underground cavities were leaking contaminants to the surface. This was achieved by first confirming the presence of these radionuclides in the Amchitka Island surface environment and, second, if the radionuclides were present, determining if the source is the underground cavity or worldwide fallout. This special sampling and analysis determined that the only nonfallout-related radionuclide detected was a low level of tritium from the Long Shot test, which had been previously documented. The tritium contamination is monitored and continues a decreasing trend due to radioactive decay and dilution.

    Full Text Available The natural colonisation of many remote oceanic islands by bats, including those of the western Indian Ocean, has been facilitated by their unique capability among mammals for powered flight. In the western Indian Ocean region, only the Malagasy islands of Madagascar and the Comoros archipelago have been naturally colonised by non-volant mammals. Despite their greater potential for inter-island dispersal, and thus gene transfer, endemicity of Chiroptera in the western Indian Ocean islands is high. Given their vulnerability to stochastic and anthropogenic disturbances, greater focus needs to be placed on investigating the demographic and ecological history of bats on Western Indian Ocean islands to safeguard not only their future, but also the ecosystem functioning on these islands, for which they are undoubtedly such an integral part. Here, I summarise the taxonomic and life history information available on bats from Western Indian Ocean islands and highlight knowledge gaps and conservation issues that threaten the continued persistence of some species.

    We investigated the breeding performance of American black ducks (Anas rubripes) on Smith Island, Chesapeake Bay, to improve our understanding of island black duck breeding ecology and to make management recommendations to enhance productivity. During 1995-96, we implanted 56 female black ducks with 20-g radio transmitters and tracked 35 of the individuals through the breeding season to locate nests, determine nest fate, and identify brood habitat. We also increased preseason banding efforts and compared capture characteristics over 12 years with those from the Deal Island Wildlife Management Area, a banding site on the mainland of Tangier Sound. A low rate of nesting (37%), lack of renesting, and poor hatching success (31%) indicated that island salt marsh habitats present a harsh environment for breeding black ducks. Black ducks located 11 of 13 nests (85%) in black needlerush (Juncus roemerianus) marsh where they were vulnerable to flooding from extreme tides and to egg predators. No nests were found on forested tree hammocks, a feature that distinguishes Smith Island from nearby South Marsh and Bloodsworth Islands. Nest predators included red foxes (Vulpes vulpes), herring gulls (Larus argentams), fish crows (Corvus ossifragus), and, potentially, Norway rats (Rattus norvegicus). Unlike mainland red foxes, foxes radio tracked on Smith Island were found to be capable swimmers and effective low marsh predators. We found shoreline meadows of widgeon grass (Ruppia maritima) to be important foraging sites for black ducks and suspected that the virtual absence of fresh water in this high salinity environment (1217+ ppt) to incur some cost in terms of growth and survival of ducklings. Preseason bandings revealed a high proportion of banded adults and a strong positive correlation in age ratios with the Deal Island banding site. This latter finding strongly suggests a negative universal effect of storm tides on nest success for Tangier Sound black ducks. Management to

    Steward, K.J.; Laford, H.D. [URS Consultants, Inc., Seattle, WA (United States)

    1995-12-31

    This case study describes the design, construction, and operation of a bioremediation pile on Adak Island, which is located in the Aleutian Island chain. Approximately 1,900 m{sup 3} of petroleum-contaminated soil were placed in the bioremediation pile. The natural bioremediation process was enhanced by an oxygen and nutrient addition system to stimulate microbial activity. Despite the harsh weather on the island, after the first 6 months of operation, laboratory analyses of soil samples indicated a significant (80%) reduction in diesel concentrations.

  1. Studying Islands: On Whose Terms? Some Epistemological and Methodological Challenges to the Pursuit of Island Studies

    Directory of Open Access Journals (Sweden)

    Godfrey Baldacchino

    2008-05-01

    Full Text Available The pursuit of nissology, or island studies, calls for a re-centering of focus from mainland to island, away from the discourse of conquest of mainlanders, giving voice and platform for the expression of island narratives. Yet, studying islands ‘on their own terms’, in spite of its predilection for “authenticity”, is fraught with epistemological and methodological difficulties. The insider/outsider distinction does not work all that well when it comes to islands, where hybridity is the norm. This paper seeks to extend this debate, grappling especially with the contributions of Grant McCall and Peter Hay to the sparse literature. Five dilemmas related to indigenous island geographies are presented and discussed, in a semi-autobiographical style.

  2. Researching Pacific island livelihoods: mobility, natural resource management and nissology.

    Science.gov (United States)

    Christensen, Andreas E; Mertz, Ole

    2010-01-01

    Small island literature is vast in focus and aim, and is rooted in many different disciplines. The challenge is to find common grounds for researching small islands conceptually and theoretically. The aim of this article is to comment on how to research small islands, including a discussion on contemporary theories of nissology and conceptual analytical frameworks for island research. Through a review of selected case-study-based island literature on changing livelihoods coming out of the South Pacific, we wish to illustrate and discuss advantages of finding common grounds for small island studies. The focus is on two dimensions of island livelihood, migration and natural resource management, both of which are significant contributors in making island livelihoods and shaping Pacific seascapes. We argue that there is still a substantial lack of studies targeting small island dynamics that are empirical and interdisciplinary in focus and link socio-economic and ecological processes of small island societies at temporal and analytical scales.

    The Long Island Power Authority (LIPA) has teamed with Stony Brook University (Stony Brook or SBU) and Farmingdale State College (Farmingdale or FSC), two branches of the State University of New York (SUNY), to create a “Smart Energy Corridor.” The project, located along the Route 110 business corridor on Long Island, New York, demonstrated the integration of a suite of Smart Grid technologies from substations to end-use loads. The Smart Energy Corridor Project included the following key features: -TECHNOLOGY: Demonstrated a full range of smart energy technologies, including substations and distribution feeder automation, fiber and radio communications backbone, advanced metering infrastructure (AM”), meter data management (MDM) system (which LIPA implemented outside of this project), field tools automation, customer-level energy management including automated energy management systems, and integration with distributed generation and plug-in hybrid electric vehicles. -MARKETING: A rigorous market test that identified customer response to an alternative time-of-use pricing plan and varying levels of information and analytical support. -CYBER SECURITY: Tested cyber security vulnerabilities in Smart Grid hardware, network, and application layers. Developed recommendations for policies, procedures, and technical controls to prevent or foil cyber-attacks and to harden the Smart Grid infrastructure. -RELIABILITY: Leveraged new Smart Grid-enabled data to increase system efficiency and reliability. Developed enhanced load forecasting, phase balancing, and voltage control techniques designed to work hand-in-hand with the Smart Grid technologies. -OUTREACH: Implemented public outreach and educational initiatives that were linked directly to the demonstration of Smart Grid technologies, tools, techniques, and system configurations. This included creation of full-scale operating models demonstrating application of Smart Grid technologies in business and residential

  18. Ambae Island, Vanuatu (South Pacific)

    Science.gov (United States)

    2005-01-01

    The recently active volcano Mt. Manaro is the dominant feature in this shaded relief image of Ambae Island, part of the Vanuatu archipelago located 1400 miles northeast of Sydney, Australia. About 5000 inhabitants, half the island's population, were evacuated in early December from the path of a possible lahar, or mud flow, when the volcano started spewing clouds of steam and toxic gases 10,000 feet into the atmosphere. Last active in 1996, the 1496 meter (4908 ft.) high Hawaiian-style basaltic shield volcano features two lakes within its summit caldera, or crater. The ash and gas plume is actually emerging from a vent at the center of Lake Voui (at left), which was formed approximately 425 years ago after an explosive eruption. Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwest slopes appear bright and southeast slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations. Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Geospatial-Intelligence Agency (NGA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena

  19. Island studies as a decolonial project

    Directory of Open Access Journals (Sweden)

    Yaso Nadarajah

    2016-11-01

    Full Text Available The phenomenon of colonialism influenced the cultures, economies, and politics of the majority of the world’s population. The subsequent decolonization process has likewise had profound affects on colonized societies. Island societies undergoing decolonization face many of the same pressures and challenges as do mainland societies, yet island spatiality and the history of island colonization itself has left former and present-day island colonies with distinctive colonial legacies. From the Caribbean to the Arctic to the Pacific to the Indian Ocean to the Mediterranean, colonial and decolonial processes are creating tensions between maintenance of the culture of indigenous peoples, economic development, cultivation of cultural heritage, political modernization, status on the global stage, democratic governance, and educational achievement. We call for an island studies perspective on decolonization, emphasizing the importance of appropriately positioning expert knowledge relative to the needs of colonized and indigenous peoples and highlighting the pitfalls of neocolonialsim. We thus lay the groundwork for island studies as a decolonial project.

  20. Feedback-charging a metallic island

    Science.gov (United States)

    Schaller, Gernot

    2017-03-01

    We consider electronic transport through a single-electron quantum dot that is tunnel-coupled to an electronic lead and a metallic island. A background reservoir keeps the metallic island at a thermal state with the ambient temperature, while the charge accumulated on the island is reflected in a time-dependent chemical potential. Without feedback, a current would flow through the system until the chemical potentials of island and lead are equilibrated. A feedback loop can be implemented by a quantum point contact detecting the dot state, classical processing of the result and appropriate feedback actions on the electronic tunneling rates taken, with the objective to direct the current in a preferred direction. Since we directly take the detector counting statistics into account, this automatically includes measurement errors in the description. When mainly the rates are modified but hardly any energy is exchanged with the system, this feedback loop effectively implements a Maxwell demon, capable of transporting electrons against an electric bias and thereby charging the metallic island. Once the feedback protocol is stopped, the metallic island simply discharges. We find that a quantitative detector model may be useful for a realistic statistical description of feedback loops.

  1. Active ageing as lifestyle on Croatian islands

    Directory of Open Access Journals (Sweden)

    Klempić-Bogadi Sanja

    2014-01-01

    Full Text Available The main feature of Croatian islands, in addition to their beautiful nature, is the fact that they are demographically and sociologically one of the most threatened areas affected by ageing. The ageing of the island population is the result of a long-term depopulation caused by the continuous emigration of the younger working-active population over the past hundred years, but also by the retirement return migration in the last thirty years. The most critical situation is on small islands where the majority of population is aged over 60 and this has a significant impact on all aspects of island life. The research conducted on small islands in the Šibenik archipelago in 2011 has shown that older people live alone, with no significant health problems limiting their daily activities, in their own households (homes, on modest pensions, and many of them supplement their income through agriculture. They very often financially help their children, who live mostly in nearby mainland cities. The necessity of self-reliance, due to the lack of younger generations, forces the inhabitants of Croatian island to lead an active life until their old age. Although they are no longer actively employed, they still continue to contribute significantly to the family and society through their involvement in various community activities.

  2. [The health system of Brazil].

    Science.gov (United States)

    Montekio, Víctor Becerril; Medina, Guadalupe; Aquino, Rosana

    2011-01-01

    This paper describes the Brazilian health system, which includes a public sector covering almost 75% of the population and an expanding private sector offering health services to the rest of the population. The public sector is organized around the Sistema Único de Saúde (SUS) and it is financed with general taxes and social contributions collected by the three levels of government (federal, state and municipal). SUS provides health care through a decentralized network of clinics, hospitals and other establishments, as well as through contracts with private providers. SUS is also responsible for the coordination of the public sector. The private sector includes a system of insurance schemes known as Supplementary Health which is financed by employers and/or households: group medicine (companies and households), medical cooperatives, the so called Self-Administered Plans (companies) and individual insurance plans.The private sector also includes clinics, hospitals and laboratories offering services on out-of-pocket basis mostly used by the high-income population. This paper also describes the resources of the system, the stewardship activities developed by the Ministry of Health and other actors, and the most recent policy innovations implemented in Brazil, including the programs saúde da Familia and Mais Saúde.

  3. Indigenous Child Health in Brazil

    Science.gov (United States)

    del Pino Marchito, Sandra; Vitoy, Bernardino

    2016-01-01

    Abstract Improving the health status of indigenous children is a long-standing challenge. Several United Nations committees have identified the health of indigenous peoples as a human rights concern. Addressing the health of indigenous children cannot be separated from their social, cultural, and historic contexts, and any related health program must offer culturally appropriate services and a community perspective broad enough to address the needs of children and the local worlds in which they live. Evaluations of programs must, therefore, address process as well as impacts. This paper assesses interventions addressing indigenous children’s health in Brazil, ranging from those explicitly targeting indigenous children’s health, such as the targeted immunization program for indigenous peoples, as well as more generalized programs, including a focus upon indigenous children, such as the Integrated Management of Childhood Illness. The paper discusses the tensions and complexities of ethnically targeted health interventions as well as the conceptual and methodological challenge of measuring the processes employed and their impact. The lessons learned, especially the need for countries to more systematically collect data and evaluate impacts using ethnicity as an analytical category, are drawn out with respect to ensuring human rights for all within health sector responses.

  4. Epidemiology of neurocysticercosis in Brazil.

    Agapejev, S

    1996-01-01

    A revision of literature was done with the objective of tracing an epidemiologic profile of neurocysticercosis (NCC) in Brazil. The prevalence was 0.12-9% in autopsies. The frequency was 0.03-7.5% in clinical series and 0.68-5.2% in seroepidemiological studies. The disease corresponds to 0.08-2.5% of admissions to general hospitals. Patient origin was rural in 30-63% of cases. The most involved age range (64-100%) was 11 to 60 years, with a predominance (22-67%) between 21 and 40 years. The male sex was the most affected (51-80%). In the severe forms there was a predominance of urban origin (53-62%) and of the female sex (53-75%). The period of hospitalization ranges from 1 to 254 days and 33 to 50% of patients suffer 1.7 +/- 1.4 admissions. The clinical picture was variable, with a predominance of epileptic syndrome (22-92%) and intracranial hypertension (19-89%). Psychiatric manifestations were associated in 9-23% of patients. Lethality was 0.29% in terms of all diseases in general and 4.8-25.9% in terms of neurologic diseases. The asymptomatic form was detected in 6% of patients in clinical series and in 48.5% of case from autopsies. The racemose form and ventricular localization also was observed as asymptomatic form. Among the patients with cutaneous cysticercosis 65% of them showed neurologic manifestations.

  5. Development of Biosimilars in Brazil

    Directory of Open Access Journals (Sweden)

    Eduardo Braz Pereira Gomes

    2016-06-01

    Full Text Available This article presents a brief overview of the biosimilar industry in Brazil and in the world. Biosimilars are drugs originating from therapeutic or biological proteins, whose patents are expired or are going to expire. Similarly to the generic pharmaceutical industry, the expiration of patents for biologics allows the emergence of a new segment in the pharmaceutical companies. The advent of biosimilars enables to overcome of several barriers, not limited to regulatory aspects of intellectual property, but also issues related to process and technological expertise. At this level of complexity, the biosimilar manufacturers need to have the same expertise or capabilities compared to originator drug companies or holders of the patents. The importance of biosimilars is due to public health context and high costs of originator biologics. Due to an aging population, the incidence of chronic degenerative disease will increase and will have a major impact in healthcare system, in this way the emergence of biosimilars will result in substantial cost reductions.

  10. Women's motivation to become dentists in Brazil.

    Science.gov (United States)

    Kfouri, Maria G; Moyses, Samuel J; Moyses, Simone Tetu

    2013-06-01

    There has been a marked increase of women in dentistry in Brazil and in many countries around the world. The behavioral mechanisms behind the choice of career differ between men and women, and the inclination to care for others is thought by some to be more present in women than it is in men. This article discusses the reasons that lead women to choose dentistry as a profession in Brazil and the impact of feminization on the current and future profile of the profession, based on the ethics of care. The authors' review of the relevant literature published between 2000 and 2011, primarily in Brazil, suggests that whereas men have tended to choose dentistry as a good business opportunity, women have tended to base their decision on relations with other people and the flexibility of practicing the profession. Many women dentists have been found to decide to work fewer hours, report more interruptions in their activities, and have less preference to work in private practice than men dentists. In the view of service users and dental auxiliaries in Brazil, women dentists invest more time in their patients and communicate in a more pleasant, sensitive, and friendly manner. The conclusion suggests that characteristics often associated with women can affect the dental profession in Brazil by introducing greater concern with the promotion of health and other people's well-being in contrast to traditional dentistry based on curative procedures.

    During the last century, Brazil was one of the fastest growing economies in the world. Between 1901 and 2000, Brazil's Gross Domestic Product (GDP) per capita grew at an average annual rate of 4.4 percent. Brazil's long-run growth has rivaled that of counties such as South Korea, universally praised as a stellar performer. Brazil does not received the same praise. Perhaps one reason is tha...

  12. Octopus insularis (Cephalopoda: Octopodidae on the tropical coast of Brazil: where it lives and what it eats

    Directory of Open Access Journals (Sweden)

    Allan Torrecilla Batista

    Full Text Available Abstract Octopus insularis is the dominant octopus in the shallow tropical waters of the coast and oceanic islands in the North and Northeast of Brazil. Is the abundance, distribution, habitat and diet of this species on the continent the same as in oceanic islands? These factors were evaluated in seeking these answers at two areas of occurrence of Octopus insularis on the coast of Rio Grande do Norte, Brazil. Three main types of habitats were described where the species is concentrated, being: Deep Reefs (Reefs of Risca (> 15 m, Flat Biogenic Plateaus (Restingas (5-15 m and Shallow Sedimentary Reefs (Pirangi reefs (< 5 m. An aggregate spatial distribution was verified, along with bathymetric segregation in which small individuals occupied shallow areas. Regarding diet, O. insularis consumed mainly crustaceans (68% in shallow reef areas, bivalves (86% in biogenic plateau areas, and gastropods (33% in deep reef areas. The characterization of new occurring habitats, such as the area of biogenic plateau, and changes in their diet due to habitat function have shown that O. insularis occupies a broader niche than has been described in literature to date, expanding our knowledge on the ecology and biology of this octopus species of economic interest.

  6. Runaway electrons and magnetic island confinement

    Science.gov (United States)

    Boozer, Allen H.

    2016-08-01

    The breakup of magnetic surfaces is a central feature of ITER planning for the avoidance of damage due to runaway electrons. Rapid thermal quenches, which lead to large accelerating voltages, are thought to be due to magnetic surface breakup. Impurity injection to avoid and to mitigate both halo and runaway electron currents utilizes massive gas injection or shattered pellets. The actual deposition is away from the plasma center, and the breakup of magnetic surfaces is thought to spread the effects of the impurities across the plasma cross section. The breakup of magnetic surfaces would prevent runaway electrons from reaching relativistic energies were it not for the persistence of non-intercepting flux tubes. These are tubes of magnetic field lines that do not intercept the walls. In simulations and in magnetic field models, non-intercepting flux tubes are found to persist near the magnetic axis and in the cores of magnetic islands even when a large scale magnetic surface breakup occurs. As long as a few magnetic surfaces reform before all of the non-intercepting flux tubes dissipate, energetic electrons confined and accelerated in these flux tubes can serve as the seed electrons for a transfer of the overall plasma current from thermal to relativistic carriers. The acceleration of electrons is particularly strong because of the sudden changes in the poloidal flux that naturally occur in a rapid magnetic relaxation. The physics of magnetic islands as non-intercepting flux tubes is studied. Expressions are derived for (1) the size of islands required to confine energetic runaway electrons, (2) the accelerating electric field in an island, (3) the increase or reduction in the size of an island by the runaway electron current, (4) the approximate magnitude of the runaway current in an island, and (5) the time scale for the evolution of an island.

    Full Text Available The Vis Island belongs to the group of the Middle Dalmatian islands. It comprises an area of about 90.2 km2. Morphologically, three belts of highlands and two depressions with karst poljes are significant. The highest point on the island is Hum with 587 m a.s.l. theisland’s water supply is organized from the water-supply station “Korita”, situated in the central part of island, in tectonically formed depression. There are two additional capturedobjects: the well K-1 above the Komiža town and the spring “Pizdica”. The most important hydrogeological role on the island have two hydrogeological barriers, one in the KomižaBay, completely made of impermeable igneous and clastic rocks, and another one, the recently recognized relative barrier in the area of Dra~evo, Plisko and Velo polje. Since the island karst aquifer is in permanent dynamic relation with seawater, classical geologic,structural and hydrogeologic investigations have been performed with application of hydrogeochemical methods taking into account the natural chemical tracer content of groundwater and its variations in different hydrologic and vegetation conditions. Precipitationregime is very unfavorable with regard to the recharging of island’s aquifer, because dry periods are usually very long. During the summer tourist season, when the number of inhabitants and fresh water consumption considerably increase, amounts of island’sgroundwater suitable for water supply and irrigation rapidly decrease. Sometimes, insufficient quantity of fresh water on the Vis Island causes restrictions. Concerning the development of tourist potential and the present agricultural activities, summer lack ofwater is a serious restrictive factor. Some results of the performed hydrogeological study, important as a basis for island’s fresh water potential assessment, will be presented.

    Isabel Banos-González

    2016-05-01

    Full Text Available An integral dynamic model, in combination with other methods (indicators, policy and scenario analysis, is presented as a tool for sustainability assessment in island socio-ecological systems (SES. The Fuerteventura sustainability model (FSM, tested for the 1996-2011, allows a better understanding of the dynamic interactions between sustainability indicators and other factors of this island. The FSM was first applied to analyse the vulnerability of this island to climate change for the 2012-2025 period; results point to the need for urgent measures to mitigate its effects on some of the analysed indicators. A set of policy measures was then assessed from the behaviour of nine indicators and their sustainability thresholds. Finally, the FSM facilitated the development of a dynamic model of the island of El Hierro, extrapolating the features common to both SES. We propose this to be a useful tool for the quantitative sustainability assessment and the management of real island socio-ecological systems

  11. Air-driven Brazil nut effect

    Naylor, M.; Swift, Michael; King, P.

    2003-07-01

    A large heavy object may rise to the top of a bed of smaller particles under the influence of vertical vibration, the “Brazil nut effect.” Recently it has been noted that interstitial air can influence the Brazil nut rise time. Here we report that the air movement induced by vertical vibration produces a very strong Brazil nut effect for fine granular beds. We use a porous-bottomed box to investigate the mechanism responsible for this effect and to demonstrate that it is related to the piling of fine beds, first reported by Chladni and studied by Faraday. Both effects are due to the strong interaction of the fine particles with the air, as it is forced through the bed by the vibration.

  12. Brazil's sugarcane boom could affect regional temperatures

    Science.gov (United States)

    Schultz, Colin

    2013-04-01

    With the world seeking to cut its dependence on fossil fuels, the use of bioethanol and other biofuels is on the rise. In Brazil, the second largest producer and consumer of bioethanol, this has led to a boom in sugarcane production. Based on new laws and trade agreements, researchers expect Brazil's production of sugarcane-derived ethanol to increase tenfold over the next decade, with considerable land being converted for growing sugarcane. Much of this expansion is expected to come at a loss of some of the country's cerrado savannas. So while a major aim of the turn to biofuels is to reduce the transfer of carbon to the atmosphere and mitigate global climate change, the shifting agricultural activity could have direct consequences on Brazil's climate by changing the region's physical and biogeochemical properties.

    This paper describes a joint US/Brazil pilot project for rural electrification, whose major goals are: to establish technical, institutional, and economic confidence in using renewable energy (PV and wind) to meet the needs of the citizens of rural Brazil; to establish on-going institutional, individual and business relationships necessary to implement sustainable programs and commitments; to lay the groundwork for larger scale rural electrification through the use of distributed renewable technologies. The projects have supported low power home lighting systems, lighting and refrigeration for schools and medical centers, and water pumping systems. This is viewed as a long term project, where much of the equipment will come from the US, but Brazil will be responsible for program management, and sharing data gained from the program. The paper describes in detail the Brazilian program which was instituted to support this phased project.

    Directory of Open Access Journals (Sweden)

    Rafaelle C. G. Fares

    2015-01-01

    Full Text Available Dengue is the most important reemerging mosquito-borne viral disease worldwide. It is caused by any of four Dengue virus types or serotypes (DENV-1 to DENV-4 and is transmitted by mosquitoes from the genus Aedes. Ecological changes have favored the geographic expansion of the vector and, since the dengue pandemic in the Asian and Pacific regions, the infection became widely distributed worldwide, reaching Brazil in 1845. The incidence of dengue in Brazil has been frequently high, and the number of cases in the country has at some point in time represented up to 60% of the dengue reported cases worldwide. This review addresses vector distribution, dengue outbreaks, circulating serotypes and genotypes, and prevention approaches being utilized in Brazil.

    Full Text Available The objective of this paper is to estimate the indirect tax burden on food for ten income classes, based on income and household total expenditure in southern Brazil. Thus it can be seen as indirect taxes on foods affect the monetary income and consumption pattern of households. To reach the objectives proposed, will be used the Pintos-Payeras (2008 model. The database iscomposed by microdata from the Household Budgeting Survey (POF 2008-2009 and the tax regulations of the country and the southern states of Brazil. The results show that indirect taxes on food in Southern Brazil is regressive when based on income and expenditure of household , ie , the poorest people pay proportionately more taxes and have their consumption pattern highest taxed ICMS (Brazilian value added tax is the tax that contributes most to the regressivity.

  16. [Fertility transition in Brazil. Causes and consequences].

    Science.gov (United States)

    Carvalho, J A; Wong, L R

    1992-12-01

    This work examines the determinants and most important consequences of the Brazilian fertility decline. Brazil's total fertility rate declined from 6.2 in 1940 to around 3.5 in 1985. the decline began in the 1960s and amounted to 45% in about 20 years. The most rapid drop began in the late 1970s, with much of it concentrated in 2 specific periods: 1970-75 and 1980-85. The early period coincided with Brazil's so-called "Economic Miracle", a period of rapid growth accompanied however by deteriorating living conditions for the poorest population sectors. The second period coincided with the international economic crisis of the early 1980s, which was felt more strongly in Brazil than elsewhere in Latin America because of Brazil's greater degree of industrialization and closer integration into the world economy. Most of the fertility decline has been accomplished by use of just two contraceptive methods, oral contraceptives and sterilization, which together account for around 85% of contraceptive usage throughout Brazil. The third most common method, rhythm, accounts for just 6%. No reliable data on abortion are available, but it appears to be a common practice equally accessible to all socioeconomic strata despite greater associated health risks for poorer women. Brazil's fertility transition appears to have been a response to the process of proletarianization and urbanization underway in the country as well as to particular circumstances in the country. The most evident and immediate consequence of the continuous fertility decline over more than 20 years is the change in the age structure of the population. The proportions of children under 5 will decline from 14.4% in 1980 to 9.2% in 2010. The proportion aged 5-14 will decline from 24.5% to 17.4%, while the proportion aged 65 and over will increase from 4.0% to 5.6%. Brazil's recent demographic changes are scarcely reflected in development plans and political and social projects. There is almost no mention of the new

    The construction of hydropower plants unquestionably impacts the environment and communities. But countries such as Brazil have been able to build up a sophisticated socio-environmental legislation and institutions as well as a democratic and participative licensing process to protect the nature and the population affected. In some cases, plants greatly contribute towards the creation of local welfare to the population as well as good environmental practices. As a good example of best practices on socio-environmental standards, we will analyze Jirau Hydropower Project, currently under construction on the Madeira River, north of Brazil.

    2012-04-01

    In the last three decades there has been a noticeable trend in the redefinition of the nuclear family in Brazil. A recent increase in the rates of divorces and paradoxically also in the rates of marriages, the legalization of same-sex unions and adoption by these couples, and the phenomenon of teenage pregnancy are some of the aspects that reflect on the current Brazilian family. This review highlights these changes and describes how family therapists in Brazil are facing the challenge of assisting these families, in a continental-sized country with uneven distribution of training courses and healthcare assistance.

  3. Island Movements: Thinking with the Archipelago

    Directory of Open Access Journals (Sweden)

    Jonathan Pugh

    2013-05-01

    Full Text Available Whether in Homer or Plato, Shakespeare or Huxley, throughout history, thinking about islands has shaped how we think about human nature and our place in the world. However, to date archipelagos have received far less attention. This is problematic because we live, increasingly, in a world of island-island movements and not static forms. Not only in the more obvious cases of the Caribbean, Hawaii or the Philippines but, as Stratford et al (2011 say, many ‘continental forms’ like Canada and Australia are in fact archipelagos composed of thousands of island movements. To this list we can add more manufactured archipelagos: wind turbine arrays, industrial oil and military constellations. The key question therefore arises: what does it mean to think with the archipelago? This paper argues firstly that archipelagic thinking denaturalizes the conceptual basis of space and place, and therefore engages ‘the spatial turn’ presently sweeping the social sciences and humanities. Secondly, such thinking highlights the trope of what I call ‘metamorphosis’, of the adaptation and transformation of material, cultural and political practices through island movements. In both cases, I argue that thinking with the archipelago requires an important shift in how we frame analysis and engagement.

  4. One year after the Zika virus outbreak in Brazil: from hypotheses to evidence

    Directory of Open Access Journals (Sweden)

    Carlos Alexandre Antunes de Brito

    Full Text Available Abstract Zika virusis an arbovirus of the Flaviviridae family with two major strains, an Asian and an African strain. The main vectors involved in the transmission of Zika virus are the Aedes aegypti and Aedes albopictus mosquitoes. Despite its identification, discovered in 1947 in the Zika forest in Uganda, only isolated and sporadic occurrences of human infection were reported within a largely asymptomatic proportion of individuals. The first reported outbreak occurred in 2007 in the Yap Island, which belongs to the Federated States of Micronesia in the Pacific Ocean, and in French Polynesia, where high attack rates occurred and the first cases of associated Guillain-Barré syndrome were reported. From November 2014 to early 2015, the Northeast states of Brazil reported the first outbreaks of Zika virus infection, with laboratory confirmation of Zika virus circulation in April 2015. In the second quarter of 2015, the association between Zika virus infection and neurological symptoms was confirmed in adults. Moreover, in October 2015 a novel suspicion was raised based on clinical and epidemiological observations: that an association between Zika virus infection and neonatal microcephaly may exist. A year after the first reports on Zika virus in Brazil, many hypotheses and much evidence on the patterns of involvement of the disease and its complications have been produced, both in this country and others; other hypotheses still need to be clarified. This review is a synthesis of a new chapter in the history of medicine; it outlines the main results produced.

    The Earth's islands harbor a distinct, yet highly threatened, biological and cultural diversity that has been shaped by geographic isolation and unique environments. Island systems are key natural laboratories for testing theory in ecology and evolution. However, despite their potential usefulness for research, a quantitative description of island environments and an environmental classification are still lacking. Here, we prepare a standardized dataset and perform a comprehensive global environmental characterization for 17,883 of the world's marine islands >1 km(2) (∼98% of total island area). We consider area, temperature, precipitation, seasonality in temperature and precipitation, past climate change velocity, elevation, isolation, and past connectivity--key island characteristics and drivers of ecosystem processes. We find that islands are significantly cooler, wetter, and less seasonal than mainlands. Constrained by their limited area, they show less elevational heterogeneity. Wet temperate climates are more prevalent on islands, whereas desert climates are comparatively rare. We use ordination and clustering to characterize islands in multidimensional environmental space and to delimit island ecoregions, which provides unique insights into the environmental configuration and diversity of the world's islands. Combining ordination and classification together with global environmental data in a common framework opens up avenues for a more integrative use of islands in biogeography, macroecology, and conservation. To showcase possible applications of the presented data, we predict vascular plant species richness for all 17,883 islands based on statistically derived environment-richness relationships.

    Brazilian shellmounds are archaeological sites with a high concentration of marine faunal remains. There are more than 2000 sites along the coast of Brazil that range in age from 8,720 to 985 cal BP. Here, we studied the ichthyoarchaeological remains (i.e., cranial/postcranial bones, otoliths, and teeth, among others) at 13 shellmounds on the southern coast of the state of Rio de Janeiro, which are located in coastal landscapes, including a sandy plain with coastal lagoons, rocky islands, islets and rocky bays. We identified patterns of similarity between shellmounds based on fish diversity, the ages of the assemblages, littoral geomorphology and prehistoric fisheries. Our new radiocarbon dating, based on otolith samples, was used for fishery characterization over time. A taxonomical study of the ichthyoarchaeological remains includes a diversity of 97 marine species, representing 37% of all modern species (i.e., 265 spp.) that have been documented along the coast of Rio de Janeiro state. This high fish diversity recovered from the shellmounds is clear evidence of well-developed prehistoric fishery activity that targeted sharks, rays and finfishes in a productive area influenced by coastal marine upwelling. The presence of adult and neonate shark, especially oceanic species, is here interpreted as evidence of prehistoric fisheries capacity for exploitation and possibly overexploitation in nursery areas. Various tools and strategies were used to capture finfish in seasonal fisheries, over rocky reef bottoms and in sandy littoral environments. Massive catches of whitemouth croaker, main target dermersal species of South Atlantic coast, show evidence of a reduction in body size of approximately 28% compared with modern fisheries. Fishery activity involving vulnerable species, especially in nursery areas, could mark the beginning of fish depletion along the southeastern Brazilian coast and the collapse of natural fish populations.

    Scaffolded DNA origami has recently emerged as a versatile, programmable method to fold DNA into arbitrarily shaped nanostructures that are spatially addressable, with sub-10 nm resolution. Toward functional DNA nanotechnology, one of the key challenges is to integrate the bottom up self-assembly of DNA origami with the top-down lithographic methods used to generate surface patterning. In this report we demonstrate that fixed length DNA origami nanotubes, modified with multiple thiol groups near both ends, can be used to connect surface patterned gold islands (tens of nanometers in diameter) fabricated by electron beam lithography (EBL). Atomic force microscopic imaging verified that the DNA origami nanotubes can be efficiently aligned between gold islands with various inter-island distances and relative locations. This development represents progress toward the goal of bridging bottom up and top down assembly approaches. PMID:21070012

    2001-12-01

    The bathymetry of Coco's Island (UNESCO Natural and Cultural World Patrimony), located approximately 500 km from the Pacific coast of Costa Rica, is not well known. It has a high marine biodiversity and also represents a meeting site for many species traveling throughout the Pacific Ocean. The insular shelf is irregular in extension and also in bathymetric features. The northeast limit is defined by the 109.8-128.1 m contours (60-70 fathoms) while the 183 m contour (100 fathoms) practically defines the rest of the island, from which the depth gradient is steep. The maximum extension is to the northeast with a longitude of 13 km. In this context the present limits of the marine park (5 km), are insufficient to protect the whole insular shelf. Current regulation should be modified to prevent fishing activities less than 15 km from the Island.

  14. Different shades of green on small islands

    2016-11-01

    Full Text Available Many small islands exist as tourism destinations worldwide. In the 1990s, the growth of environmental consciousness led some small islands to question their mass tourism offers and to refocus on more sustainable propositions. However, it remains unclear whether hospitality firms see these sustainability related efforts as drivers of success and whether tourists value this dimension when choosing or recommending a destination. This study chose a small island destination to address these questions using data covering firm and tourism perceptions of green products. The results show that tourists tend to value green efforts with different intensities, corresponding to three segments: Light Green, Green, and Super Green. These findings should help hotels adjust their communication strategies and develop new services. Further, destination marketing organizations can devise a consistent destination strategy, integrating all stakeholders by including their most valued concepts.

  15. The floating (pathogenicity) island: a genomic dessert

    Among the prokaryotic genomic islands (GIs) involved in horizontal gene transfer (HGT) are the classical pathogenicity islands, including the integrative and conjugative elements (ICEs), the gene-transfer agents (GTAs), and the staphylococcal pathogenicity islands (SaPIs), the primary focus of this review. While the ICEs and GTAs mediate HGT autonomously, the SaPIs are dependent on specific phages. The ICEs transfer primarily their own DNA the GTAs exclusively unlinked host DNA and the SaPIs combine the capabilities of both. Thus the SaPIs derive their importance from the genes they carry (their genetic cargo) and the genes they move. They act not only as versatile high frequency mobilizers, but also as mediators of phage interference, and consequently are major benefactors of their host bacteria. PMID:26744223

    2011-01-01

    As part of the Marianas Expedition Wildlife Surveys-2010, the forest vegetation of the island of Pagan, Commonwealth of the Northern Mariana Islands (CNMI), was sampled with a series of systematic plots along 13 transects established for monitoring forest bird populations. Shrubland and grassland were also sampled in the northern half of the island. Data collected were woody plant density, tree diameter at breast height, woody plant density in height classes below 2 m, and ground cover measured with the point-intercept method. Coconut forests (Cocos nucifera) were generally found to have low native tree diversity, little regeneration of trees and shrubs in the forest understory, and little live ground cover. The sole exception was a coconut-dominated forest of the northeast side of the island that exhibited high native tree diversity and a large number of young native trees in the understory. Ironwood (Casuarina equisetifolia) forests on the northern half of the island were nearly monocultures with almost no trees other than ironwood in vegetation plots, few woody plants in the understory, and low ground cover dominated by native ferns. Mixed native forests of both northern and southern sections of the island had a diversity of native tree species in both the canopy and the sparse understory. Ground cover of native forests in the north had a mix of native and alien species, but that of the southern half of the island was dominated by native ferns and woody plants.

  17. Phosphorus deficiency in buffaloes in the state of Pará, Northern Brazil

    Full Text Available Phosphorus deficiency is the most important mineral deficiency in Brazil. In the state of Pará, this deficiency occurs in many regions, mainly in Marajó Island, where it causes important economic losses. This paper reports the epidemiology, clinical signs and pathology of phosphorus deficiency in Buffaloes in Pará. This information was obtained by visits to the farms, clinical examination and necropsies of some affected buffaloes. The disease occurs due to the low levels of P in the pastures and an incorrect or absent mineral supplementation. Also, in the Marajo Island, the high NaCl concentration in the water limits consumption of mineral supplements by the buffaloes. The main clinical signs are osteophagia, bone fractures, rising difficulties, rigid gait or stance over the carpal joints, kiphosis, abnormal stance, mainly with one foreleg dislocated cranially, joint swelling, softening of the transverse processes of the lumbar vertebrae, poor growth, weight loss, birth of small calves, and low reproductive taxes. Hemoglobinuria after parturition is also observed. Serum phosphorus varied between 2.52 and 5.43 mg/dl. At necropsy bone fractures, light bones with less resistance and enlarged medullar cavity were observed. Frequently the bones can be cut with a knife. Histologically the bones have active bone resorption with accumulation of non mineralized osteoid.

    Sea turtles are marine reptiles that undertake long migrations through their life, with limited information regarding juvenile stages. Feeding grounds (FGs), where they spend most of their lives, are composed by individuals from different natal origins, known as mixed stock populations. The aim of this study was to assess genetic composition, natal origins and demographic history of juvenile green turtles (Chelonia mydas) at the Paranaguá Estuarine Complex (PEC), Brazil, considered a Natural World Heritage site. Tissue samples of stranded animals were collected (n = 60), and 700 bp mitochondrial DNA sequences were generated and compared to shorter sequences from previously published studies. Global exact tests of differentiation revealed significant differences among PEC and the other FGs, except those at the South Atlantic Ocean. Green turtles at PEC present genetic signatures similar to those of nesting females from Ascension Island, Guinea Bissau and Aves Island/Surinam. Population expansion was evidenced to have occurred 20–25 kYA, reinforcing the hypothesis of recovery from Southern Atlantic refugia after the last Glacial Maximum. These results contribute to a better understanding of the dynamics of green turtle populations at a protected area by providing knowledge on the dispersion patterns and reinforcing the importance of the interconnectivity between nesting and foraging populations.

  1. Assesing Geographic Isolation of the Galapagos Islands

    2016-06-01

    The Galapagos Archipelago is one of the most important ecological spots in the planet due its unique biodiversity, active geology, and relatively well-preserved ecosystems. These characteristics are strongly based on the geographical isolation of the islands. On the one hand this isolation allowed the evolution processes that gave the islands their international fame and on the other hand it kept them from major human impacts that affected the vast majority of the Earth's surface. Galapagos' geographical isolation is therefore of mayor value, but it is rapidly diminishing due to the increase of marine and air transportation among islands and with the rest of the world. This increased accessibility implies enhanced risks for the ecological dynamics on the archipelago (e.g. increased risk of biological invasions, uncontrolled tourism growth, more water and energy consumption). Here, we introduce a general accessibility model to assess geographical isolation of the Galapagos Islands. The model aims to characterize accessibility in terms of human mobility by evaluating travel time to each point of the archipelago using all available transportation modalities. Using a multi criteria cost surface for marine and land areas, we estimated travel time for each surface unit using the fastest route and mode of transportation available while considering several friction factors such as surface type, slope, infrastructure, transfer points, legal restrictions, and physical barriers. We created maps to evaluate the isolation of different islands and places, highlighting the potential risks for several habitats and ecosystems. The model can be used for research and decision-making regarding island conservation, such as estimating spreading paths for invasive species, informing decisions on tourism management, and monitoring isolation changes of sensitive ecosystems.

    The Saint Peter and Saint Paul Islands are located at 0 degree 55.00' N and 29 degree 20.76'' W, at a distance of circa 550 M (nautical miles) NE from the City of Natal, RN (Northeast Region of Brazil), and comprises of many small islands and rocks of igneous plutonic origin. In 1998, a first Scientific Station was built in order to receive researchers involved in several projects. The CEPEL, as responsible by the electrical energy supply to the Scientific Station; designed and installed a PV electric energy generation system which had a power of 3.6 kWp. This system operated successfully for the last 10 years, suffering frequent maintenance. In 2006, a new design for the Scientific Station has been started aiming to improve its resources and safety. The new PV system has a maximum power of 7.8 kWp, and employs an updated technology (SMA, Germany). The equipment was integrated and submitted to intensive testing at facilities of CEPEL, and was installed and commissioned at the Islands in June 2008. Since the installation, the equipment has been operating as required, meeting the energy and water demand of the Station. The present paper describes the many steps involved in the implantation of the PV system at the Scientific Station. (author)

  3. Taxonomic survey and characterization of the habitat of aquatic insects in protected areas in a subtropical island

    Full Text Available Taxonomic inventories are the basis of several ecological studies and they enable a better understanding of the local and regional biodiversity. This paper aimed to survey the aquatic insect fauna in a subtropical island, as well as to generate information on the habitats used by the taxa found. Two regions showing a good state of environmental conservation in the Santa Catarina Island, in Santa Catarina, Brazil, were selected: “Lagoa do Peri” Municipal Park and “Desterro” Environmental Protected Area. Aquatic invertebrates were collected by using a Surber sampler (in a lotic environment and an Eckman-Birge dredger (in a lentic environment between 2009 and 2012. Sixty taxa were found, belonging to eight taxonomic orders. Thus, there were 19 new registers of aquatic insect families for Santa Catarina. At the sites of this study, 13 families already known for Santa Catarina were not observed, according to a comparison with articles published until July 2014. As for the habitat, richness differed between the types of the habitats sampled, with lower richness in the substrate “sand”. The study represents a significant contribution to knowledge on aquatic insects in Santa Catarina, especially regarding the biodiversity in islands.

  4. Brazils Role in environmental governance: Analysis of possibilities for increased Brazil-Norway cooperation

    2011-07-01

    This report examines the role played by Brazil in connection with certain international negotiations, such as the climate negotiations and the CBD. It identifies the driving factors that have influenced environmental politics and standards in Brazil, and take note of conflicts that must be discussed when Norway is seeking expanded cooperation with Brazil. In line with the mandate, FNI identifies areas of particular interest for further collaboration between the two countries, and recommend directions for supplementary Norwegian policy-making in light of a broadened scope for Norway-Brazil interaction. In recent years, the Norwegian government has initiated an extensive process aimed at reducing emissions from deforestation and forest degradation (REDD). This is the most obvious shared environmental scope between Norway and Brazil. However, given the large body of literature that already exists on this field, this report will concentrate instead on issues more on the outskirts of the REDD discourse, such as biodiversity conservation, biofuel efficiency and challenges concerning hydropower, all of which threaten to impact negatively on the Amazonian areas. In our recommendations, we cite tangible examples to illustrate issues where we believe lessons learnt in Norway may have applicability to Brazil.(auth)

  5. Local and regional effects on community structure of dung beetles in a mainland-island scenario.

    Directory of Open Access Journals (Sweden)

    Pedro Giovâni da Silva

    Full Text Available Understanding the ecological mechanisms driving beta diversity is a major goal of community ecology. Metacommunity theory brings new ways of thinking about the structure of local communities, including processes occurring at different spatial scales. In addition to new theories, new methods have been developed which allow the partitioning of individual and shared contributions of environmental and spatial effects, as well as identification of species and sites that have importance in the generation of beta diversity along ecological gradients. We analyzed the spatial distribution of dung beetle communities in areas of Atlantic Forest in a mainland-island scenario in southern Brazil, with the objective of identifying the mechanisms driving composition, abundance and biomass at three spatial scales (mainland-island, areas and sites. We sampled 20 sites across four large areas, two on the mainland and two on the island. The distribution of our sampling sites was hierarchical and areas are isolated. We used standardized protocols to assess environmental heterogeneity and sample dung beetles. We used spatial eigenfunctions analysis to generate the spatial patterns of sampling points. Environmental heterogeneity showed strong variation among sites and a mild increase with increasing spatial scale. The analysis of diversity partitioning showed an increase in beta diversity with increasing spatial scale. Variation partitioning based on environmental and spatial variables suggests that environmental heterogeneity is the most important driver of beta diversity at the local scale. The spatial effects were significant only at larger spatial scales. Our study presents a case where environmental heterogeneity seems to be the main factor structuring communities at smaller scales, while spatial effects are more important at larger scales. The increase in beta diversity that occurs at larger scales seems to be the result of limitation in species dispersal

  6. Vulnerability assessment of small islands to tourism: The case of the Marine Tourism Park of the Gili Matra Islands, Indonesia

    2016-04-01

    Full Text Available The Indonesian government is currently directing its focus of development on the optimum uses of marine and coastal ecosystem services including the marine and coastal tourism. One of the main locus of coastal and marine tourism is the small islands tourism such as Gili Matra Islands among others. Small islands tourism is one of the favourite touristic activities because the destination provides beauty, exotism, aesthetic and a diversity of natural habitats including the warm, clear and attractive water. Tourism is being considered as a development instrument in order to boost a country’s economy and has become part of the global industry. However, tourism is also one of the actors that is responsible for environmental depletion, due to the constructions of buildings and tourism activities. This paper aims to study the level of vulnerability in small islands to tourism as a basis of integrated small islands management in Indonesian conservation area. The group of islands in this study consists of three islands namely Gili Ayer Island, Gili Meno Island and Gili Trawangan Island (known as Gili Matra Islands that were observed using Small Islands Vulnerability Index (SIVI. The results indicate that Gili Matra Islands have a vulnerability status from low into moderate, ranging from 2.25 to 2.75. Gili Ayer Island has the highest vulnerability with SIVI of 2.75 (Moderate, followed by Gili Meno Island with SIVI of 2.50 (Low and Gili Trawangan Island with SIVI of 2.25 (Low. The driving factor of vulnerability is the intensive utilization of marine tourism activities. Tourism is the sole stress to Gili Matra Island’s ecosystem due to its direct damaging impact and reducing its environmental quality. The vulnerability index which was built from the coastline, coral reef, live coral reef, and development area was applicable to assess the small island’s vulnerability in Indonesia, especially for coral island.

    It is shown that plasma viscosity does not influence the magnetic island rotation directly. Nevertheless, it leads to nonstationarity of the plasma velocity. This nonstationarity is the reason of the viscosity effect on island rotation. (author)

  3. Vascular plant diversity of the Paracel Islands, China

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available The Paracel Islands (Xisha Islands comprise a group of tropical islands that are located south of mainland China and have a particular natural flora. Based on a literature search and our own investigations, we present here a checklist of plants for 24 of the Paracel Islands. We also report an analysis of plant diversity, its distribution and relationship with that of neighboring regions. A total of 396 vascular plants were recorded which belonged to 262 genera and 85 families. Of these, 220 were wild species and 176 were cultivated. As a whole, the islands do not possess a rich flora; however, there are major differences in plant diversity among islands. The flora consists in large part of tropical elements, typical of tropical coral islands of China. The flora is most closely connected to that of Hainan Island, and closely related to those of Taiwan of China, Indochina, Malaysia, Indonesia and the Philippines.

  5. Topological description of Easter Islander palmar dermatoglyphics.

    Science.gov (United States)

    Goodson, C S; Meier, R J

    1986-10-01

    A sample of 594 Easter Islander palms was analyzed according to the topological method. Some suggestions for clarification of the topological approach were made, including clearer definition of the palmar triradii and substitution of the term "profile" for "formula." The frequency of Easter Islander profiles was compared against British and Australian Aborigine samples (Loesch, 1974; 1983a,b) and found to be significantly different for two of the ten most common combinations. The individual pattern elements, pattern intensities, a-b count, A-line exit, and atd angle were described, with population comparisons made when they were available.

  6. How a bird is an island

    Full Text Available Abstract Replicate adaptive radiations occur when lineages repeatedly radiate and fill new but similar niches and converge phenotypically. While this is commonly seen in traditional island systems, it may also be present in host-parasite relationships, where hosts serve as islands. In a recent article in BMC Biology, Johnson and colleagues have produced the most extensive phylogeny of the avian lice (Ischnocera to date, and find evidence for this pattern. This study opens the door to exploring adaptive radiations from a novel host-parasite perspective. See research article: http://www.biomedcentral.com/1741-7007/10/52

  9. Abortion in Brazil: legislation, reality and options.

    Science.gov (United States)

    Guedes, A C

    2000-11-01

    Abortion is illegal in Brazil except when performed to save the woman's life or in cases of rape. This paper gives a brief history of parliamentary and extra-parliamentary efforts to change abortion-related legislation in Brazil in the past 60 years, the contents of some of the 53 bills that have been tabled in that time, the non-governmental stakeholders involved and the debate itself in recent decades. The authorities in Brazil have never assumed full public responsibility for reproductive health care or family planning, let alone legal abortion; the ambivalence of the medical profession is an important obstacle. Most politicians avoid getting involved in the abortion debate, but the majority of bills in the 1990s have favoured less restrictive legislation. Incremental legislative and health service changes could help to improve the situation for women. Advocacy is probably the most important action, to promote an environment conducive to change. Clandestine abortion is a serious public health problem in Brazil, and the inadequacy of family planning services is one of the causes of this problem. The solutions should be made a priority for the Brazilian public health system.

  11. Dengue situation in Brazil by year 2000

    Directory of Open Access Journals (Sweden)

    Hermann G Schatzmayr

    2000-01-01

    Full Text Available Dengue virus types 1 and 2 have been isolated in Brazil by the Department of Virology, Instituto Oswaldo Cruz, in 1986 and 1990 respectively, after many decades of absence. A successful continental Aedes aegypti control program in the Americas, has been able to eradicate the vector in most countries in the 60's, but the program could not be sustained along the years. Dengue viruses were reintroduced in the American region and the infection became endemic in Brazil, like in most Central and SouthAmerican countries and in the Caribbean region, due to the weaning of the vector control programs in these countries. High demographic densities and poor housing conditions in large urban communities, made the ideal conditions for vector spreading. All four dengue types are circulating in the continent and there is a high risk of the introduction in the country of the other two dengue types in Brazil, with the development of large epidemics. After the Cuban episode in 1981, when by the first time a large epidemic of dengue hemorrhagic fever and dengue shock syndrome have been described in the Americas, both clinical presentations are observed, specially in the countries like Brazil, with circulation of more than one dengue virus type. A tetravalent potent vaccine seems to be the only possible way to control the disease in the future, besides rapid clinical and laboratory diagnosis, in order to offer supportive treatment to the more severe clinical infections.
