  1. Investigating Beyond the Scales. Interactive governance analysis of small-scale fisheries in the San Andrés Archipelago, Colombia

    Randin, Olivier

    2013-01-01

    Small-scale fisheries are complex, diverse and dynamic. Therefore, to understand these fisheries, governance is favoured to management as a more comprehensive analytical framework that aims to catch issues and challenged beyond the technical aspects of management. Following a phronesis approach, embedding theory into reality, I chose the case study of the small-scale fisheries of the San Andrés archipelago for analysis. To do so, the interactive governance theory and its conceptual framework ...

  2. Space schemes of ecological zonation and morphology of the atolls lagoons and reef complex of an oceanic archipelago of the Caribbean: San Andres and Providence (Colombia)

    The oceanic atolls and reef-complexes of the Archipelago of San Andres and Providencia exhibit semi-enclosed to rather open lagoon basins, where various characteristic bottom habitats occur. Certain areas of the lagoon floor are covered by sediments, being in some settings vegetated by algae or sea grass, and other areas by coralline framework of different types according to the composition and dominance of coral species and to their morphology and level of reef development. This study seeks to determine the spatial distribution patterns of lagoon bottom habitats based on the analysis of gradients of most relevant physical factors. Patterns in the occurrence and abundance of most habitats became evident in relation with wave-energy level, water depth, and the occurrence of islands. Some morphological reef types are oriented in a preferential direction and show spatial arrangements of development that are presumably related to prevailing current speed and direction and wave exposure

  3. Marine macroalgae in the agronomy and potential use of floating sargassum for manure production in the San Andres and Providencia Archipelago, Colombia

    An account is made on the use of marine macroalgae in agronomy and the potential that floating Sargassum arriving to san Andres and Providencia has for this activity. This Sargassum, which has been a nuisance for the tourist economy of the islands, promises to be an excellent resource for manure production

    Heavy metal pollution in water is generally associated with industrial and municipal discharges into rivers, estuaries and lagoons. Once metals are in the water column, they may be taken up by organisms, deposited in the sediments or remain for some period in the water itself. The deposition rate in sediments depends on, among other factors, metal concentration in surface sediments. The concentrations of heavy metals in sediments of coastal, estuarine and lagoon environments have been determined by many workers. For the past several years, we have been interested in determining trace and heavy metal concentrations in the lagoons in Mexico to establish the levels of metal pollution. The work reported here is the completion of our ongoing study in San Andres lagoon. San Andres lagoon is located north of two industrial ports, Tampico and Altamira. In this industrial zone, the basins of the Panuco and Tamesi Rivers are localized and have industrial effluent throughout the year. All these activities and the input of the Tigre River, which runs through an agricultural and cattle-raising region, may affect the biogeochemistry of the San Andres lagoon. In the present work, we report concentrations of Cd, Co, Cu, Fe, Mn, Ni, Zn and Pb in sediments of San Andres lagoon. The measurements were made in different seasons; Rain-84 (August-September 1984); North (October-December 1984); Dry (April 1985); and Rain-85 (April-June 1985). 13 refs., 1 fig., 2 tabs.

  8. A Transnational World Fractured but Not Forgotten: British West Indian Migration to the Colombian Islands of San Andrés and Providence

    Sharika Crawford

    2011-06-01

    Full Text Available This article examines British West Indian migration to the Colombian archipelago of San Andrés and Providence in the late nineteenth to early twentieth century. While the United Fruit plantations, Panama Canal, oil fields in Venezuela, and railroad projects in Central America generated a strong demand for a large West Indian workforce, no such development took place on San Andrés and Providence. As a result, the profile of West Indian migration looks different than to the Spanish-speaking circum-Caribbean, with more professionals and merchants and fewer unskilled laborers. In the absence of mass migration, there was less hostility toward West Indian newcomers to San Andrés and Providence islands.

  9. A correlation for miscible flood displacement efficiency in the San Andres with NMR relaxation

    This paper reports that a set of San Andres crystalline dolomite cores was examined for the relationship between pore attributes discernible from NMR relaxation and miscible flooding displacement efficiency. A strong correlation was observed between the inferred abundance of long relaxation time components and laboratory measured residual oil to a multicontact miscible displacement process. NMR relaxation time distribution proved to be a simple, noninvasive, nondestructive indicator of flow performance in the 12 San Andres dolomite samples examined. Spin-lattice relaxation measurements were conducted on clean, brine saturated core end pieces from plugs taken adjacent to those used for flow displacement studies. Sample data were deconvoluted into a distribution of relaxation times, which is ultimately related to surface-to-volume ratio distribution. The median relaxation time was determined to be the most sensitive statistics to convey flow performance. Residual oil saturation was adequately represented by a power law function of the median relaxation time

    1999-01-01

    An evaluation of total immunoglobulin E (IgE) and dengue serostatus in 168 subjects from San Andrés Island, Colombia, revealed altered levels of IgE in 89% of the population. IgE levels were higher in patients with a history of dengue or with a current secondary or current primary infection than in subjects with no exposure (P = 0.01). Dengue infection accounted for 23% of the variation in IgE levels.

  11. Origins of the Salado, Seven Rivers, and San Andres salt margins in Texas and New Mexico: Revision 1: Topical report

    The present boundaries of the San Andres, Seven Rivers, and Salado salts generally lie along the periphery of the Palo Duro and Tucumcari Basins. Various geologic mechanisms occurring singularly or in combination determined the positions of the salt margins. These mechanisms include nondeposition of salt and syndepositional and postdepositional dissolution. In New Mexico, San Andres units pinch out against the Pedernal and Sierra Grande Uplifts, indicating that nondeposition established the original salt margins there. Syndepositional dissolution of exposed Upper San Andres salts occurred in response to Guadalupian upwarp of the basin margins. Triassic erosion differentially removed Permian salt-bearing formations along the uplifts. Late Tertiary dissolution is indicated by fill of north-south trending collapse valleys. In Texas, Guadalupian upwarp along the Amarillo Uplift caused pinchout of Units 2 and 3 in the Lower San Andres and influenced the deposition of subsequent salt-bearing strata. The discontinuity of Upper San Andres evaporites across the Amarillo Uplift suggests syndepositional dissolution. Along the eastern and northeastern basin margin, dissolution may have accompanied Triassic erosion of locally uplifted Upper Permian strata. Tertiary dissolution is recognized beneath anomalously thick Ogallala Formation sections that overlie collasped Permian strata. 49 refs., 31 figs., 2 tabs

    Transmission of Zika virus (ZIKV) was first detected in Colombia in September 2015. As of April 2016, Colombia had reported over 65,000 cases of Zika virus disease (ZVD). We analysed daily surveillance data of ZVD cases reported to the health authorities of San Andres and Girardot, Colombia, between September 2015 and January 2016. ZVD was laboratory-confirmed by reverse transcription-polymerase chain reaction (RT-PCR) in the serum of acute cases within five days of symptom onset. We use daily incidence data to estimate the basic reproductive number (R0) in each population. We identified 928 and 1,936 reported ZVD cases from San Andres and Girardot, respectively. The overall attack rate for reported ZVD was 12.13 cases per 1,000 residents of San Andres and 18.43 cases per 1,000 residents of Girardot. Attack rates were significantly higher in females in both municipalities (p Zika outbreak was 1.41 (95% confidence interval (CI): 1.15-1.74) in San Andres and 4.61 (95% CI: 4.11-5.16) in Girardot. Transmission of ZIKV is ongoing in the Americas. The estimated R0 from Colombia supports the observed rapid spread. PMID:27452806

  18. Survey of benthic dinoflagellates associated to beds of Thalassia testudinumin San Andres Island, Seaflower biosphere reserve, Caribbean Colombia

    In order to determine the occurrence of epiphytic toxic dinoflagellates in the coastal waters of San Andres Island, Caribbean Colombia, we analyzed the sea grass beds on the northern and eastern sides of the island. We found seven species of toxicogenic dinoflagellates, belonging to the genera Prorocentrum and Ostreopsis. The cell densities were generally low if compared with previous studies in other Caribbean sites, ranging from 0 to 836 cells/dry weights. The species encountered are known to produce toxins causing the diarrheic shellfish poisoning and ciguatera, poisonings which have been documented in the island.

  20. APPLICATION OF WATER-JET HORIZONTAL DRILLING TECHNOLOGY TO DRILL AND ACIDIZE HORIZONTAL DRAIN HOLES, TEDBIT (SAN ANDRES) FIELD, GAINES COUNTY, TEXAS

    Michael W. Rose

    2005-09-22

    The San Andres Formation is one of the major hydrocarbon-producing units in the Permian Basin, with multiple reservoirs contained within the dolomitized subtidal portions of upward shoaling carbonate shelf cycles. The test well is located in Tedbit (San Andres) Field in northeastern Gaines County, Texas, in an area of scattered San Andres production associated with local structural highs. Selected on the basis of geological and historical data, the Oil and Gas Properties Wood No. 1 well is considered to be typical of a large number of San Andres stripper wells in the Permian Basin. Thus, successful completion of horizontal drain holes in this well would demonstrate a widely applicable enhanced recovery technology. Water-jet horizontal drilling is an emerging technology with the potential to provide significant economic benefits in marginal wells. Forecast benefits include lower recompletion costs and improved hydrocarbon recoveries. The technology utilizes water under high pressure, conveyed through small-diameter coiled tubing, to jet horizontal drain holes into producing formations. Testing of this technology was conducted with inconclusive results. Paraffin sludge and mechanical problems were encountered in the wellbore, initially preventing the water-jet tool from reaching the kick-off point. After correcting these problems and attempting to cut a casing window with the water-jet milling assembly, lateral jetting was attempted without success.

    It is known that the encrusting and excavating Caribbean sponge Cliona delitrix may increase its abundance near sources of sewage. To ascertain whether its current conspicuousness in leeward reefs of San Andrés Island (SW Caribbean, Colombia) is related to organic pollution from local raw sewage discharges, quantitative data on density and cover of this sponge and other benthic components was obtained from belt and line transects at seven stations along the shallow (5-10 m deep) terrace.

    2013-01-01

    Full Text Available The bathroom of temazcal is a knowledge of pre-Hispanic roots still practiced in rural and indigenous communities in our country. Studies on the temazcal have focused on its forms of construction and operation, however, the many therapeutic benefits temazcal bath attached to the human body, and women in particular, not have been sufficiently documented. In this case, two communities of the Oaxacan mixteca were studied: Santiago Yolomecatl and San Andrés Chicahuaxtla. In this study, a questionnaire was applied to 20 per cent of families in each of the communities, a questionnaire to allopathic doctors and six stories of life at temazcaleras. The results indicate a coincidence between patients and doctors in the study populations on the medicinal uses of the temazcal bath: after childbirth and for muscle aches, however, interviewed temazcaleras indicate diseases that cures this bath are: angina, flu, rheumatism,scars, muscle aches after childbirth and cramping. For its part, doctors support the idea of preserving the temazcal bath because it is a healing means to treat diseases through steam and faster recovery of the body. The constructivist analysis of the responses gathered in questionnaires and life stories shows that the medicinal uses of the temazcal, before being recognised as such go through a process of evaluation, filtration and social construction. This process of acceptance, perception and recognition occurs through rules of knowledge, ideological connotations, rules and socialsymbols.

El artículo propone que la designación actual del colegio, como una escuela de arte, puede ser una consecuencia tardía de la inestable relación entre arte y religión, tal como fue cultivada dentro de la institución franciscana. Se trató, por lo tanto, de una superposición del valor religioso sobre el artístico, mediante el cual se adoctrinaba a los estudiantes. El artículo enfatiza en la apropiación de destrezas artísticas por parte de los indígenas, quienes adquirieron dominio sobre estas artes, las mercadearon y provocaron una inesperada tensión en las concepciones franciscanas acerca de la religión y el uso del arte.

  7. A "coca-cola" shape: cultural change, body image, and eating disorders in San Andrés, Belize.

    Anderson-Fye, Eileen P

    2004-12-01

    Eating disorders have been associated with developing nations undergoing rapid social transition, including participation in a global market economy and heavy media exposure. San Andrés, Belize, a community with many risk factors associated with the cross-cultural development of eating disorders, has shown remarkable resistance to previously documented patterns, despite a local focus on female beauty. Drawing on longitudinal person-centered ethnography with adolescent girls, this article examines why this community appears exceptional in light of the literature. First, community beauty and body image ideals and practices are explicated. Then, a protective ethnopsychology is proposed as a key mediating factor of the rapid socio-cultural change among young women. Finally, possible nascent cases of eating disordered behavior are discussed in light of their unique phenomenology: that is, having to do more with economic opportunity in the tourism industry and less with personal distress or desire for thinness. Close, meaning-centered examination of eating and body image practices may aid understanding and prevention of eating disorders among adolescents undergoing rapid social change in situations of globalization and immigration.

  11. Development and recent activity of the San Andrés landslide on El Hierro, Canary Islands, Spain

    2016-05-01

    Extremely voluminous landslides with a long run-out (also known as megalandslides) on oceanic volcanic islands are infrequent denudational processes on such islands. At the same time, they represent a major geological hazard that must be looked into to avoid negative consequences for the inhabitants of these islands. Their occurrence can be related to periods of intense seismo-volcanic activity, similar to that which occurred on El Hierro Island over 2011-2012. Landslides on volcanic islands are studied using onshore and offshore geological, geophysical and geomorphological records, considering their unique triggering conditions (e.g. lava intrusions, eruptive vents, magma chamber collapses). Previous work has pointed out similarities between specific cases of landslides on volcanic islands and deep-seated gravitational slope deformations (DSGSDs) which are typical in high mountain settings. Nevertheless, the methodological approaches and concepts used to investigate DSGSDs are not commonly applied on volcanic islands studies, even though their use may provide new information about the development stage, recent movements and future hazards. Therefore, this approach for studying the San Andrés landslide (SAL) on El Hierro (Canary Islands) has been developed applying a detailed morphological field mapping, an interpretation of digital elevation models, structural measurements, kinematic testing, and a precise movement monitoring system. The acquired information revealed a strong structural influence on the landslide morphology and the presence of sets of weakened planes acting as the sliding surfaces of the SAL or secondary landslides within its body. The presence of secondary landslides, deep erosive gullies, coastal cliffs and high on-shore relative relief also suggests a high susceptibility to future landslide movement. Direct monitoring on the landslide scarps and the slip plane, performed between February 2013 and July 2014, using an automated optical

    del suelo. Dos humedales del estudio fueron de borde y uno de tipo interno. Algunos factores fisico-químicos que influyen sobre la descomposición de la materia orgánica vegetal fueron evaluados. El modelo de regresión que mejor de ajustó al comportamiento de descomposición fue el simple de raíz cuadrada. La interacción del tiempo con factores bióticos y abióticos determinó la perdida de biomasa foliar. Las mayores tasas de degradación se obtuvieron en humedales de borde; microambientes acuáticos y edáficos húmedos; sobre la especie A. germinans; y en los lugares con macrofauna consumidora asociada. En las etapas tempranas de descomposición
    se presentó la mayor velocidad de degradación. En general, el menor porcentaje medio de biomasa remanente después de seis semanas de incubación lo presentó A. germinans (35%, respecto a R. mangle (44% y L. racemosa (51%. La pedogénesis en San Andrés isla es autóctona, y reconocer el aporte de la necromasa

    1985-01-01

    This report presents the results of mineralogic and petrographic analyses performed on samples of salt-bearing rock from a potential repository site in the Palo Duro Basin, Texas. The samples are from Permian Units 4 and 5 salt, Lower San Andres Formation, J. Friemel No. 1 well, Deaf Smith County, Texas. The mineralogic and petrographic data were obtained from polished thin sections cut parallel to the axis of the core for each sample. The polished thin sections were examined in order to determine the abundances of soluble (halite) and insoluble components (anhydrite, clay, carbonate, quartz, gypsum, etc.). The information reported here includes mineral associations (detrital, authigenic, cement, alteration, etc.), texture, grain size, and sedimentary fabrics. The report also includes representative photomicrographs with superimposed bar scales. Photomicrographs of polished thin sections have the up-core direction designated. X-ray diffraction was also used for identification of soluble and insoluble minerals. 7 refs., 2 tabs.

    Full Text Available Los depósitos de la Aloformación Punta San Andrés (Plio-Pleistoceno, registran la evolución de diferentes estilos de sistemas fluviales. Durante la primera etapa de la misma evolución, se desarrollaron sistemas de carga mixta, con canales de baja sinuosidad y alta participación de depósitos de planicie de inundación. Durante la segunda etapa, se verificó el cambio hacia un sistema de canales de mayor sinuosidad, entrelazados, donde los depósitos de planicie de inundación no tuvieron tanto protagonismo. Finalmente, la tercera etapa se caracterizó por el desarrollo de un sistema fluvial entrelazado clásico, sin preservación de depósitos de planicie de inundación. Durante la acumulación de la Aloformación Punta San Andrés, la glacioeustacia en asociación con el clima condicionó directamente el balance entre la tasa de generación de acomodación y el aporte sedimentario. Sin embargo, el análisis comparativo de los diversos índices e indicadores (arquitectura fluvial, paleosuelos, etc. ha mostrado una variabilidad para los sistemas bajo estudio la cual puede asignarse a diferentes jerarquías de procesos. De esta manera, se identificaron ciclos de agradación fluvial representados por una alternancia de alta frecuencia entre paleosuelos vérticos y cálcicos. En este caso las fluctuaciones en el nivel de base fueron las responsables de los cambios cíclicos en la tasa de generación de espacio de acomodación y de aporte sedimentario. La evolución de los sistemas depositacionales identificados puede asignarse a ciclos de mayor jerarquía, los cuales controlaron el diseño del drenaje mediante cambios en el espacio de acomodación y representan cambios en la tasa de generación de espacio de acomodación relacionados a cambios glacieustáticos de escala global.The deposits of the Punta San Andrés Alloformation (Plio-Pleistocene register the evolution of different styles of fluvial systems.

  19. Rock-physics-based carbonate pore type characterization and reservoir permeability heterogeneity evaluation, Upper San Andres reservoir, Permian Basin, west Texas

    Dou, Qifeng; Sun, Yuefeng; Sullivan, Charlotte

    2011-05-01

    In addition to mineral composition and pore fluid, pore type variations play an important role in affecting the complexity of velocity-porosity relationship and permeability heterogeneity of carbonate reservoirs. Without consideration of pore type diversity, most rock physics models applicable to clastic rocks for explaining the rock acoustic properties and reservoir parameters relationship may not work well for carbonate reservoirs. A frame flexibility factor ( γ) defined in a new carbonate rock physics model can quantify the effect of pore structure changes on seismic wave velocity and permeability heterogeneity in carbonate reservoirs. Our study of an Upper San Andres carbonate reservoir, Permian Basin, shows that for core samples of given porosity, the lower the frame flexibility factor ( γ), the higher the sonic wave velocity. For the studied reservoir, samples with frame flexibility factor ( γ) 3.85 indicate either dominant interparticle pore space in dolopackstone or microcrack pore space in dolowackstone or dolomudstone. Using the frame flexibility factor ( γ), different porosity-impedance and porosity-permeability trends can be classified with clear geologic interpretation such as pore type and rock texture variations to improve porosity and permeability prediction accuracy. New porosity-permeability relations with γ classification help delineate permeability heterogeneity in the Upper San Andres reservoir, and could be useful for other similar carbonate reservoir studies. In addition, results from analysis of amplitude variation with offset (AVO) and impedance modeling indicate that by combining rock physics model and pre-stack seismic inversion, simultaneous estimation of porosity and frame flexibility factor ( γ) is quite feasible because of the strong influence of carbonate pore types on AVO especially when offset is large.

  1. San Andres Rift, Nicaraguan Shelf: A 346-Km-Long, North-South Rift Zone Actively Extending the Interior of the "Stable" Caribbean Plate

    Carvajal, L. C.; Mann, P.

    2015-12-01

    The San Andres rift (SAR) is an active, 015°-trending, bathymetric and structural rift basin that extends for 346 km across the Nicaraguan platform and varies in bathymetric width from 11-27 km and in water depth from 1,250 to 2,500 m. We used four 2D regional seismic lines tied to two offshore, industry wells located west of the SAR on the Nicaraguan platform to map normal faults, transfer faults, and possibly volcanic features with the rift. The Colombian islands of San Andres (26 km2) and Providencia (17 km2) are footwall uplifts along west-dipping, normal fault bounding the eastern margin of the rift. Mapping indicates the pre-rift section is Late Cretaceous to Oligocene in age and that the onset of rifting began in the early to middle Miocene as shown by wedging of the Miocene and younger sedimentary fill controlled by north-south-striking normal faults. Structural restorations at two locations across the rift shows that the basin opened mainly by dip-slip fault motions producing a total, east-west extension of 18 km in the north and 15 km in the south. Structural restoration shows the rift formed on a 37-km-wide, elongate basement high - possibly of late Cretaceous, volcanic origin and related to the Caribbean large igneous province. Previous workers have noted that the SAR is associated with province of Pliocene to Quaternary seamounts and volcanoes which range from non-alkaline to mildly alkaline, including volcanic rocks on Providencia described as andesites and rhyolites. The SAR forms one of the few recognizable belts of recorded seismicity within the Caribbean plate. The origin of the SAR is related to Miocene and younger left-lateral displacement along the Pedro Banks fault to the north and the southwestern Hess fault to the south. We propose that the amount of left-lateral displacement that created the rift is equivalent to the amount of extension that formed it: 18-20 km.

    Full Text Available El buceo es un uso alternativo y no consuntivo de la biodiversidad marina que, debidamente practicado, tiene bajo impacto ambiental, estimula la conservación de los arrecifes y es una opción económica para habitantes de áreas arrecifales o con potencial para el buceo. El archipiélago de San Andrés, Providencia y Santa Catalina, declarado por UNESCO Reserva Mundial de la Biosfera Seafl ower, con 65.000 km2 de Áreas Marinas Protegidas y un extenso complejo arrecifal coralino, tiene condiciones para convertirse en un sitio de buceo de nivel mundial. Sin embargo, es poco conocido. Esta investigación analiza el potencial económico del buceo en esta región y lo compara con el de sitios muy reconocidos como Bonaire y Gran Caimán. Mediante análisis de la disponibilidad a pagar de buzos visitantes, se intenta valorar el buceo y se caracteriza el tipo de buzos que vienen al archipiélago. Se encontró disposición a pagar cifras superiores a las que se paga actualmente en otras partes del Caribe. Con un potencial estimado en $241 millones de dólares de ingresos anuales, el buceo es una interesante alternativa de desarrollo económico sostenible para estas islas que, a pesar de recibir 360.000 turistas al año, aún presentan un 66.9% de pobreza y altos niveles de desempleo.

    Background We are reporting for the first time the in vivo anti-inflammatory activity of extracts and fractions, and in vitro anti-inflammatory activity of pure compounds, all isolated from Pseudopterogorgia elisabethae collected at the Providencia (chemotype 1) and San Andrés (chemotype 2) Islands (SW Caribbean). Methods Extracts from P. elisabethae were fractionated on silica gel to yield fractions: F-1 (pseudopterosins PsQ, PsS and PsU) and F-2 (amphilectosins A and B, PsG, PsK, PsP and PsT and seco-pseudopterosins seco-PsJ and seco-PsK) from chemotype 1, and F-3 (elisabethatrienol, 10-acetoxy-9-hydroxy- and 9-acetoxy-10-hydroxy-amphilecta-8,10,12,14-tetraenes (interconverting mixture) and amphilecta-8(13),11,14-triene-9,10-dione) from chemotype 2. By using preparative RP-HPLC and spectroscopic means, we obtained the pure PsG, PsK, PsP, PsQ, PsS, PsT, PsU, seco-PsK and the interconverting mixture of non-glycosylated diterpenes (IMNGD). The anti-inflammatory properties of extracts and fractions were evaluated using in vivo model "12-O-tetradecanoyl-phorbol-acetate (TPA)-induced mouse ear oedema". The activities of pure compounds and of the IMNGD were evaluated using in vitro assays myeloperoxidase (MPO) release (by human polymorphonuclear neutrophils (PMNs)), nitric oxide release (by J-774 cells) and scavenger activity on NO. Results In the in vivo anti-inflammatory assay, extracts and F-3 showed low inhibition levels of inflammation compared to indomethacin, F-1 and F-2. Additionally, we evaluated the MPO release to the inflammation site, and found a marked inhibition of MPO levels by all extracts and fractions, even superior to the inhibition shown by indomethacin. Furthermore, in the MPO in vitro assay, IMNGD, PsQ, PsS, PsT and PsU, exhibited higher inhibition levels compared to dexamethasone and indomethacin. In the NO release in vitro, IMNGD, PsP and PsT were the most potent treatments. Finally, because the PsG, PsP and seco-PsK did not exhibit any NO

Charlottesville: University of Virginia Press, 1998. xii + 197 pp. (Cloth US$ 42.50, Paper US$ 18.50 In his most recent theoretical work, Traite du Tout-Monde, Edouard Glissant stresses the virtues of what he calls "archipelagic thinking." "The entire world is becoming an archipelago," he asserts (1997:194, and for this reason we need to distance ourselves from both insular and continental ways of thinking if we are to register the complexities of that global creolization process. The archipelago is situated between the solitary confines of the islands that constitute it and the expansive territory of the mainland toward which it points, relating the one to the other while retaining its own indeterminately distinct identity. For Glissant, actual archipelagos such as the Caribbean are exemplary sites for understanding the complex new relations that ambivalently and chaotically join together all the hitherto unconnected parts of the world. As a consequence of this, the need for understanding the Caribbean as an archipelago becomes ever more pressing: the Caribbean must be considered in its archipelagic totality, as a region that can only be adequately understood through comparative, cross-cultural analysis focusing less on its discrete parts than on the way these parts exist in relation with and to one another.

    Full Text Available Exploitation of the Guadalupe fur seal (GFS during the XVIII and XIX centuries almost extirpated the species. GFS were distributed from the Revillagigedo islands (Mexico to the gulf of Farallones (USA. At present, reproductive colonies are found at Guadalupe Island and San Benito Archipelago (SBA. The aim of this work was to analyze the process of re-colonization and the current status of GFS at SBA. The first births and the occupation of the west island of the SBA are also reported. Census data from 1997 to 2007 indicated an annual growth rate for the population of 21.6%. The population size, growth tendency of the colony, reproductive biology, and food preferences were also studied. A total of 2,227 GFS were counted at SBA. Three squid species (Loligo opalescens, Onychoteuthis banksii, Dosidicus gigas were found to be the main dietary components. Territoriality, activity patterns, and reproductive behavior were similar for the seals from Guadalupe Island and SBA. The mean growth rate for pups from SBA was calculated and compared to that of the pups at Guadalupe Island (SBA: 6.7 ± 1.4 kg, 68.9 ± 2.64 cm; Guadalupe Island: 5.9 ± 0.5 kg, 67.29 ± 4.3 cm. The length of food foraging trips by females was measured, suggesting that the SBA colony is probably near an important feeding area. Maternal care patterns could indicate different strategies of nursing-foraging trips between the SBA and Guadalupe Island. The population of fur seals at SBA is expected to increase as there are no limitations in terms of reproductive space or available food resources in the area.La explotación del lobo fino de Guadalupe (LFG durante los siglos XVIII y XIX casi extinguió a la especie.

    Full Text Available El diseño conceptual involucró un enfoque sistémico, abarcando los siguientes componentes: a Descripción del sistema pesquero: la población pesquera artesanal fue estimada en 307, y concentra sus actividades en cuatro sitios pesqueros. Los pescadores tienen edades que oscilan en general entre los 41 y 51 años, presentan bajo grado de escolaridad y tienen ingresos entre 1,0 y 2,5 SMLMV. La pesquería es multiespecífica y está dirigida a la extracción de diferentes especies de peces, el molusco Strombus gigas y la langosta Panulirus argus. El arte de pesca dominante es la línea de mano con anzuelo seguido del arpón. La flota artesanal es de 120 embarcaciones. El producto es comercializado en el sitio pesquero y adquirido por intermediarios que se encargan de su venta al consumidor final. b Régimen de pesca: la producción anual de pescado fue estimada en 303.662 kg y el esfuerzo

For those who lived through the Gargamelle epic, his name is linked with the success of the great bubble chamber that made possible the 1973 discovery of neutral currents. A graduate of Paris's famous Ecole Polytechnique which produced so many great names in particle physics, André Rousset, a native of southern France, joined Louis Leprince-Ringuet's famous laboratory at the Polytechnique in 1954. Among other topics, Rousset played a part in the cosmic ray experiments at the Pic du Midi in the Pyrénées and designed heavy liquid bubble chambers. A Professor at the Ecole des Mines from 1960 onwards, he became deputy director of Louis Leprince-Ringuet's laboratory in 1964.

He pioneered, together with his advisor Stueckelberg, the renormalization group, one of the fundamental ideas in quantum field theory that underlies the modern theory of phase transitions as well as asymptotic freedom and the quest for unification of all the particle interactions.   André was among the very first staff members of CERN, which at the beginning was a small group of theorists at the Niels Bohr Institute in Copenhagen, headed by Bohr himself.  When the group moved to Geneva, they first occupied a set of barracks in Cointrin, next to the airport, before moving to the University of Geneva, and then finally settling on the Meyrin site. André was our last direct contact with our nomadic origins. The importance of André’s early work on the renormalization group was recogn...

  2. Island Movements: Thinking with the Archipelago

    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.

  5. Shear Wave Splitting Beneath the Galapagos Archipelago

    Fontaine, F. R.; Burkett, P. G.; Hooft, E. E.; Toomey, D. R.; Solomon, S. C.; Silver, P. G.

    2004-12-01

    We report measurements of teleseismic shear wave splitting in the Galápagos Archipelago. The inferred lateral variations in azimuthal anisotropy allow us to examine the dynamics of an evolving hotspot-ridge system. The data are from SKS and SKKS phases, as well as S waves from deep sources, recorded by a relatively dense network of 10 portable broadband seismometers deployed from 1999 to 2003 for the IGUANA (Imaging Galápagos Upwelling and Neotectonics of the Archipelago) experiment and from the GSN broadband station in Santa Cruz (PAYG). We find a delay time between fast and slow shear waves of 0.4 to 0.9 s and fast polarization directions of N85-90° E beneath five stations at the leading and southern edge of the archipelago. Despite clear seismic signals, we did not find any anisotropy at the six stations located in the interior of the archipelago. For those stations that show shear wave splitting, there is an increase in the delay time toward the expected location of the Galápagos hotspot at the western edge of the archipelago. With the exception of Española, fast polarization directions (N85-90° E) are close to the current direction of absolute plate motion of the overlying Nazca plate (N91° E). The lack of azimuthal anisotropy in the interior of the archipelago is interpreted as an absence of strongly oriented mantle fabric beneath these stations. The apparent isotropy in this dynamic region, where we expect considerable mantle strain, is surprising. It is not likely that the olivine a-axis is oriented vertically beneath the interior of the archipelago as the Galápagos plume is thought to lie at the western edge. It is also unlikely that there are two layers of perpendicularly-oriented anisotropy which are solely confined to the center of the archipelago. However, there appears to be some correlation between the region of apparent isotropy and a zone of anomalously low upper mantle velocities imaged beneath Santiago and Marchena from surface waves by

  15. San Marino.

    1985-02-01

    San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to

  20. André Danjon et l'informatique.

    Arsac, J.

    There is not any paper by André Danjon about computer science. The only way to know his ideas about it is through his action. At the end of the fifties, several scientists in astronomy and astrophysics had been convinced that a computer would be of great help in their research works. André Danjon immediatly agreed that it was a good idea. He greatly supported them in the process of having a computer bought by the Meudon Observatory. A computing center was started there in 1959. As soon as 1957, André Danjon had initiated a French association for computing, the "association française de calcul". This association provoked a world meeting of associations for information processing in Paris in 1959, where the IFIPS has been created.

  8. Hydrogeology of the Azores volcanic archipelago (Portugal)

    Cruz, J.; Coutinho, R.; Antunes, P.; Freire, P.

    2009-04-01

    The archipelago of the Azores is made of nine islands of volcanic origin located in the North Atlantic Ocean, with an area of 2333 km2 and approximately 237500 inhabitants, which are 98% dependant from groundwater sources for their water consumption. Therefore, groundwater is a resource that plays a vital role as drinking water source and as ecosystem support matrix. Nevertheless, besides the environmental, social and economical value of groundwater, this resource is subject to an increase pressure and in several islands water quality deterioration is shown by monitoring data. This pressure is also shown by the 42.7% increase expected for domestic use until the year 2020 at the Azores, with higher groundwater abstraction. The Azores climate can be considered as marine temperate, which is reflected by the low thermal amplitude and high precipitation. A well-established difference between a dry season and a colder and wet season occurs, as from October to March about 75% of the annual precipitation is registered. The average annual precipitation at the Azores is 1930 mm, exceeding by far the average annual actual evapotranspiration, which is 581 mm. Recharge rates range from 8.5% to 62.1%, and the highest values are observed at Pico, Terceira, Faial, São Miguel and Graciosa islands, especially in areas where the terrain is covered by recent basaltic lava flows and the soil cover is sparse. Groundwater resources estimates point to a total volume of about 1600x106 m3/yr. Values above the recharge median, equal to 101.3x106 m3/yr. were estimated for the São Miguel, São Jorge, Terceira and Flores islands. Despite differences in the islands growth, as a result of successive volcanic eruptions of various types, groundwater occurrence can be described in function of two main aquifers systems: (1) the basal aquifer system, which corresponds to fresh-water lenses floating on underlying salt water, and (2) perched-water bodies, which are usually drained by springs spread in

  9. The influence of the geological setting on the morphogenetic evolution of the Tremiti Archipelago (Apulia, Southeastern Italy)

    Andriani, G. F.; Walsh, N.; Pagliarulo, R.

    2005-01-01

    The Tremiti Archipelago (Southern Adriatic Sea), also called Insulae Diomedae from the name of the Greek hero who first landed there, is an area of high landscape and historical value. It is severely affected by significant geomorphologic processes dominated by mass movements along the coast that constitute the most important and unpredictable natural hazard for the population and cultural heritage. Coastal erosion is favoured by the peculiar geological and structural setting, seismic activity, weathering, development of karst processes, and wave action. The present paper reports on descriptive and qualitative evaluation of the factors controlling landslides and coastline changes based on medium-term in situ observation, detailed surface surveys at selected locations since 1995, and historic and bibliographic data. The Tremiti Archipelago is part of an active seismic area characterised by a shear zone separating two segments of the Adriatic microplate that have shown different behaviour and roll back rates in the subduction underneath the Apennines since middle Pleistocene. Although coastal morphology can be basically considered to be the result of wave action, the continual action of subaerial processes contributes effectively to the mechanism of shoreline degradation. Weathering mainly affects the marly calcisiltites and calcilutites of the Cretaccio Fm. and the friable and low cemented calcarenites and biomicrites of the San Nicola Fm. The cliffs are characterised by different types of failure such as lateral spreads, secondary topples, rock falls and slides. At the Isle of San Nicola, landslides are controlled by the contrast in competence, shear strength and stiffness between the Pliocene re-crystallised dolomitic calcarenites and calcisiltites and the Miocene marly calcilutites and calcisiltites. At the Isles of San Domino and Caprara rock falls are attributed to the undercutting of waves at the base of the cliffs.

  11. New geological data of New Siberian Archipelago

    Sobolev, Nikolay; Petrov, Evgeniy

    2014-05-01

    The area of New Siberian Archipelago (NSA) encompasses different tectonic blocks is a clue for reconstruction of geological structure and geodynamic evolution of East Arctic. According to palaeomagnetic study two parts of the archipelago - Bennett and Anjou Islands formed a single continental block at least from the Early Palaeozoic. Isotope dating of De Long Islands igneous and sedimentary rocks suggests Neoproterozoic (Baikalian) age of its basement. The De Long platform sedimentary cover may be subdivided into two complexes: (1) intermediate of PZ-J variously deformed and metamorphosed rocks and (2) K-KZ of weakly lithified sediments. The former complex comprises the Cambrian riftogenic volcanic-clastic member which overlain by Cambrian-Ordovician turbiditic sequence, deposited on a continental margin. This Lower Palaeozoic complex is unconformably overlain by Early Cretaceous (K-Ar age of c.120 Ma) basalts with HALIP petrochemical affinities. In Anjou Islands the intermediate sedimentary complex encompasses the lower Ordovician -Lower Carboniferous sequence of shallow-marine limestone and subordinate dolomite, mudstone and sandstone that bear fossils characteristic of the Siberian biogeographic province. The upper Mid Carboniferous - Jurassic part is dominated by shallow-marine clastic sediments, mainly clays. The K-KZ complex rests upon the lower one with angular unconformity and consists mainly of coal-bearing clastic sediments with rhyolite lavas and tuffs in the bottom (117-110 Ma by K-Ar) while the complexe's upper part contains intraplate alkalic basalt and Neogene-Quaternary limburgite. The De-Long-Anjou block's features of geology and evolution resemble those of Wrangel Island located some 1000 km eastward. The Laptev Sea shelf outcrops in intrashelf rises (Belkovsky and Stolbovoy Islands) where its geology and structure may be observed directly. On Belkovsky Island non-dislocated Oligocene-Miocene sedimentary cover of littoral-marine coal

  12. A conservation strategy in San Andres Island: school projects and values in environmental education

    With the scope of showing and preserving an island endangered species, the Swanka turtle, a campaign and an environmental education program were conducted. The campaign consisted in showing the species to the community, its characteristics and its threats, through mass media and visits to different local schools. The environmental education program was carried out through a Scholar Environmental Project, which consisted on the conformation of an environmental group, where cognitive, attitudinal and participative aspects were worked together. Using a constrictive methodology the children developed some knowledge about the species and Its habitats. The scope was that they modified attitudes and behaviors towards situations that contribute to environmental damage; the reinforcement of values was the central point during all the activities. The knowledge gained by the pupils and the observed changes on their attitudes and participation show the positive results that arise when the action of environmental education focuses on the people and not the resources that are to be preserved

    Schaaf, P. E. G.; Solis-Pichardo, G.; Hernandez-Trevino, T.; Villanueva, D.; Arrieta, G. F.; Rochin, H.; Rodriguez, L. F.; Bohnel, H.; Weber, B.

    2015-12-01

    Islas Marias Archipelago consists of four islands located in the mouth of the Gulf of California. Lithologically three of them (Maria Madre, San Juanito, and Maria Cleofas) are quite similar with a 165-170 Ma metamorphic basement, 75-85 Ma intrusive and extrusive rocks, and a sedimentary sandstone cover, which according to its foraminiferous content recorded multiple uplift and subsidence events related to the opening of the Gulf. However, these units are absent on Maria Magdalena island which is positioned between the other islands. Here, instead, oceanic lithosphere with pillow lavas and gabbroic sills, intercalated with sandstones form the dominant outcrops. Their geochemical and isotopic characteristics are similar to N-MORB with epsilon Nd values around +10 and 87Sr/86Sr of 0.70290. The gabbros are not older than 22 Ma. Magdalena island was obviously uplifted separately from the other islands of the archipelago, probably along a now hidden transform fault system along the East Pacific Rise. Metamorphic and igneous rocks of the other islands can be correlated to lithologically similar units in the Los Cabos Block, Baja California, or to the continental margin units in Sinaloa, Nayarit and Jalisco states when looking at their geochemical and geochronological signatures. Paleomagnetic studies on 35 sampling sites from all 4 islands give evidence for relatively small scale tectonic movements.

  5. Coexistence of reef organisms in the Abrolhos Archipelago, Brazil.

    Lins de Barros, M M; Castro, C B; Pires, D O; Segal, B

    2000-12-01

    The first study on coexistence of reef benthic organisms in Brazilian coral reefs was done in three localities of the Abrolhos Archipelago. Organisms were recorded in concentric circle samples (10 and 20 cm in diameter) randomly laid on transects. Type and frequency of "coexistence events" between pairs of organisms were determined. Most frequent organisms (massive and branched coralline algae, Favia gravida, and Agaricia agaricites) also had many significant positive coexistence events. These results might be related to the abundances of these organisms. The most frequent coral (Siderastrea stellata), however, exhibited only a few significant coexistence events (9% of 32 tests). Since the great majority of events were positive, and since there was high variation in the species/groups involved in significant events in different localities, benthic communities of Abrolhos Archipelago may well be structured primarily by abiotic rather than biotic factors.

  7. Archipelago Tidal Flats in Korea: Sedimentological and Geoheritage Significance

    Woo, Kyung Sik; Chun, SeungSoo; Moon, Kyong O.

    2015-04-01

    Over one thousand islands with rocky shores are distributed and concentrated along the southwestern coast of the Korean Peninsula. Various tidal flats formed along the rocky coasts of the archipelago have been developed due to the relative decrease in accommodation space by slow sea-level rise on broad marginal epicontinental seas during the Holocene. Sedimentation and evolution on these archipelago tidal flats (ATF) show quite distinctive and various tidal flat patterns, depending upon the location and direction of rocky shores which have been constantly influenced by monsoon winds reversely changing with season. Generally ATF is characterized by surrounding wave-dominated sand flats along the outside of the archipelago and by broad tide-dominated mud flats in its central part with spring tidal range reaching up to 6 meters. The open-coast outside sand flats and inner mud flats are completely different in terms of sedimentation and the evolution of sedimentary sequences. The former has been deposited by the transgressive sedimentation with strongly destructive and weakly constructive wave/tide processes, forming relative thin and younger (ca. 3,000 yrs BP) remnant storm-dominated sandflat units. The latter has been deposited by continuous transgressive settling with constructive tidal processes during Holocene, forming relative thick and older (from ca. 7,000 yrs BP) mud-flat units. Geomorphological features and the geological evolution of the ATF (Shinan archipelago and Yoobudo islands in Seocheon) display a quite distinctive pattern of ongoing geological processes from the Wadden Sea tidal flats which was already inscribed as World Natural Heritage. Therefore, the Outstanding Universal Values of the Korean ITF for criteria (vii) and (viii) should provide a strong support for the additional World Natural Heritage Site.

    Troelstra, S. R.; Jonkers, H.M.; Rijk, de, J.

    1996-01-01

    A systematic description of the distributional patterns of larger symbiont-bearing benthic Foraminifera from the Spermonde Archipelago (Sulawesi, Indonesia) and their relation with local coral reef growth is presented. The larger Foraminiferal assemblages and diversity indices correspond with the diversity of Scleractinia and marine plants on the Spermonde platform. Our results indicate that the group is an excellent biomonitor for the health condition of recent coral reefs and a valuable too...

    Reproduction and recruitment are key processes that replenish marine populations. Here we use the Palau archipelago, in the western Pacific Ocean, as a case study to examine scales of connectivity and to determine whether an oceanographic model, incorporating the complex reef architecture, is a useful predictor of coral recruitment. We tested the hypothesis that the reefs with the highest retention also had the highest densities of juvenile coral density from 80 field sites. Field comparisons...

  8. André-Louis Cholesky mathematician, topographer and army officer

    Brezinski, Claude

    2014-01-01

    Outside the professional circles of topography and applied mathematics, the life and work of André-Louis Cholesky (1875–1918) are still relatively unknown to the scientific community. This new book appreciably widens the exposure of his remarkable personal achievements in topography and mathematics to a much larger international audience.   Cholesky is also interesting to historians because he is a perfect representative of the "scientists engineers" that, since the early 19th century, had issued from the French scientific high schools. Because they had received a high level of mathematical education, they were able to innovate in their practice of engineering. In the case of Cholesky, this resulted in original contributions in artillery, topography, numerical analysis and graphical calculation. In addition, the book places his education and works within the history of several European countries through the 17th to 19th centuries.   The book begins with Cholesky's biography, followed by his family’s hi...

  15. Temporal analysis of remotely sensed turbidity in a coastal archipelago

    Suominen, Tapio; Tolvanen, Harri

    2016-07-01

    A topographically fragmental archipelago with dynamic waters set the preconditions for assessing coherent remotely sensed information. We generated a turbidity dataset for an archipelago coast in the Baltic Sea from MERIS data (FSG L1b), using CoastColour L1P, L2R and L2W processors. We excluded land and mixed pixels by masking the imagery with accurate (1:10 000) shoreline data. Using temporal linear averaging (TLA), we produced satellite-imagery datasets applicable to temporal composites for the summer seasons of three years. The turbidity assessments and temporally averaged data were compared to in situ observations obtained with coastal monitoring programs. The ability of TLA to estimate missing pixel values was further assessed by cross-validation with the leave-one-out method. The correspondence between L2W turbidity and in situ observations was good (r = 0.89), and even after applying TLA the correspondence remained acceptable (r = 0.78). The datasets revealed spatially divergent temporal water characteristics, which may be relevant to the management, design of monitoring and habitat models. Monitoring observations may be spatially biased if the temporal succession of water properties is not taken into account in coastal areas with anisotropic dispersion of waters and asynchronous annual cycles. Accordingly, areas of varying turbidity may offer a different habitat for aquatic biota than areas of static turbidity, even though they may appear similar if water properties are measured for short annual periods.

  16. The Idea of the Archipelago: Contemplating Island Relations

    Elaine Stratford

    2013-05-01

    Full Text Available Creative, innovative, and timely research on islands and island futures is warranted and pressing, not least because island(ers are poorly served by established tropes of them as subordinate to continents or mainlands. Opportunities exist to provide a more thoroughgoing account of island life and island relations, and the seven papers in this special issue address that task. In works that consider islands in the Timor Sea, the Caribbean, the Pacific, Atlantic and Southern Oceans, and that span several different disciplinary frames—archival-historical, critical theoretical, literary, cultural, geopolitical, sociological and artistic—these papers evidence both the diversity of approach to thinking with the archipelago, and numerous points in common. Among the latter is an understanding that island relations are built on connection, assemblage, mobility, and multiplicity, and a commitment to critically examine the ways in which these entanglements affect and give effect to island life. The models of island relationality brought to light by this collective focus on the archipelago reveal new and diverse connections of island peoples with their physical and cultural environments, and with the world beyond; create spaces for growing resilience, association and engagement; and invite further study.

  18. Marine actinomycetes from Madeira Archipelago preliminary taxonomic studies

    Ilda Santos Sanches

    2014-06-01

    Full Text Available The oceans cover 70 % of the Earth´s surface and harbor most of the planet´s biodiversity. However the microbiological component of this diversity remains relatively unexplored. Marine actinomycetes, are a robust resource of chemically prolific novelty. Producing structurally unique biological active secondary metabolites, generating a valuable source for innovative biotechnology and drug discovery[1,2]. As a consequence, the ecological role of actinomycetes and their marine ecosystems may no longer be neglected. It is crucial to move our research efforts into ocean regions for which we know little or nothing about the indigenous microbial diversity. The Portuguese Archipelago, Madeira is located in the Macaronesian Atlantic region, emerging from the African tectonic plate, found in the extreme south of the Tore-Madeira ridge, has a unique biogeography and biodiversity. These distinctive characteristics combined with the fact that Madeira have never been explored, as far as indigenous marine actinomycetes are concerned, makes it from the scientific point of view, the perfect target for our studies. From 662 marine sediment samples collected along Madeira Archipelago (Figure 1 during June of 2012, covering depths from 10-1310 m, a total of 421 actinomycete strains were isolated. In a previous study, an assemblage of 82 strains was selected for taxonomic identification, having into account representative morphological diversity characteristics of the actinomycetes, isolated from Madeira Archipelago. Based on 16S rRNA gene sequencing, it was observed that the genera Streptomyces, Micromonospora and Salinispora were predominant, 81% [3]. Additionally, in a recent study, our team selected 168 strains with Salinispora look-alike morphological features. From these 28 strains were identified as belonging to the seawater-obligate marine actinomycete genus Salinispora. Representing the first report of Salinispora spp. in the Macaronesian Atlantic Ocean

Thishas led to more epidemiological research into violence, and a stronger medical interest in the etiology and preventionof violence. However, epidemiological research on the prevalence of violence in different societies is stillmainly criminological in nature, being based on information about violence that has come to the attention of thepolice or processed in the courts. The study of the relationship between alcohol use and violent behaviour is alsopredominantly based on police and court materials, although an increasing number of emergency room andhospitalization studies have examined the role of alcohol in injuries caused by violence.There are two basic methodological approaches in the study of the relationship between alcohol use andviolence. The alcohol-involvement studies estimate the extent to which drinking by the offender or the victim

    Full Text Available El trabajo analiza la obra del filósofo Arturo Andrés Roig, recientemente fallecido, desde la perspectiva del humanismo latinoamericano, corriente de pensamiento crítico de fuerte presencia en América Latina. El núcleo de la propuesta teórica de Roig está dado por la problemática del sujeto o, como él prefería llamarla, de la sujetividad. Luego de proponer una breve periodización de la obra del filósofo, el artículo pasa revista a los aportes de Roig en torno a este tema, en los distintos campos en que incursionó: sus propuestas metodológicas para la lectura de textos latinoamericanos, su concepción de la Historia de las ideas como reconstrucción del itinerario del sujeto americano, el a priori antropológico como herramienta teórica y heurística del filosofar en América Latina y, finalmente, sus desarrollos en el campo de la ética.

  2. Are the 1/3-Octave Band 63- and 125-Hz Noise Levels Predictive of Vessel Activity? The Case in the Cres-Lošinj Archipelago (Northern Adriatic Sea, Croatia).

    Picciulin, Marta; Sebastianutto, Linda; Fortuna, Caterina Maria; Mackelworth, Peter; Holcer, Draško; Gospić, Nikolina Rako

    2016-01-01

    A 3-years sea ambient-noise (SAN) monitoring was carried out in the Cres-Lošinj Archipelago (Croatia), where a bottlenose dolphin population is threatened by unregulated nautical tourism. A total of 540 5-min SAN samples were collected and analyzed in an Indicator 11.2.1 (Marine Strategy Framework Directive) perspective. The 1/3-octave band center frequencies of 63 and 125 Hz (re 1 μPa.rms) proved to be predictive of local predominant ship type over time. However, the noisiest band level was centered on 200 Hz. We therefore suggest measuring a wider frequency band than those requested in Indicator 11.2.1. PMID:26611038

  3. Dispersal has inhibited avian diversification in Australasian archipelagoes.

    Weeks, Brian C; Claramunt, Santiago

    2014-09-22

    Different models of speciation predict contrasting patterns in the relationship between the dispersal ability of lineages and their diversification rates. This relationship is expected to be negative in isolation-limited models and positive in founder-event models. In addition, the combination of negative and positive effects of dispersal on speciation can result in higher diversification rates at intermediate levels of dispersal ability. Using molecular phylogenies to estimate diversification rates, and wing morphology to estimate dispersal ability, we analysed the influence of dispersal on diversification in the avifauna of Australasian archipelagoes. Contrary to expectations given the fragmented nature of island systems, the relationship between dispersal ability and diversification rate was monotonically negative. While multiple mechanisms could generate this pattern, they all share a phase of range expansion that is decoupled from speciation. PMID:25100701

  4. Environmental contaminants in bald eagle eggs from the Aleutian archipelago

    Anthony, R.G.; Miles, A.K.; Ricca, M.A.; Estes, J.A.

    2007-01-01

    We collected 136 fresh and unhatched eggs from bald eagle (Haliaeetus leucocephalus) nests and assessed productivity on eight islands in the Aleutian archipelago, 2000 to 2002. Egg contents were analyzed for a broad spectrum of organochlorine (OC) contaminants, mercury (Hg), and stable isotopes of carbon (??13C) and nitrogen (??15N). Concentrations of polychlorinated biphenyls (??PCBs), p,p???- dichlorodiphenyldichloroethylene (DDE), and Hg in bald eagle eggs were elevated throughout the archipelago, but the patterns of distribution differed among the various contaminants. Total PCBs were highest in areas of past military activities on Adak and Amchitka Islands, indicating local point sources of these compounds. Concentrations of DDE and Hg were higher on Amchitka Island, which was subjected to much military activity during World War II and the middle of the 20th century. Concentrations of ??PCBs also were elevated on islands with little history of military activity (e.g., Amlia, Tanaga, Buldir), suggesting non-point sources of PCBs in addition to point sources. Concentrations of DDE and Hg were highest in eagle eggs from the most western Aleutian Islands (e.g., Buldir, Kiska) and decreased eastward along the Aleutian chain. This east-to-west increase suggested a Eurasian source of contamination, possibly through global transport and atmospheric distillation and/or from migratory seabirds. Eggshell thickness and productivity of bald eagles were normal and indicative of healthy populations because concentrations of most contaminants were below threshold levels for effects on reproduction. Contrary to our predictions, contaminant concentrations were not correlated with stable isotopes of carbon (??13C) or nitrogen (??15N) in eggs. These latter findings indicate that contaminant concentrations were influenced more by point sources and geographic location than trophic status of eagles among the different islands. ?? 2007 SETAC.

  6. SANS studies of polymers

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H2O/D2O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    Iva Saganić

    2008-01-01

    Full Text Available The topic of this paper is ecological evaluation of the Cres-Lošinj archipelago and the way it could be used for tourism purposes. Rapid growth of population and increasing human economic activity influence the quality of the environment. That is why the concept of sustainable development has been made, as well as new kind of tourism - eco-tourism or sustainable tourism. Today there is a small number of regions with preserved nature. The Cres-Lošinj archipelago is one of them. There is a large number of preserved plant and animal species on the archipelago, as well as some rural areas with preserved local architecture. With the development of eco-tourism, this archipelago would get the image of the area with preserved and authentic natural and cultural surroundings and healthy living environment.

    We report the recording and interpretation of an unreversed seismic profile between Blythe, Arizona and Ensenada, Baja California, using an explosive source in a drilled hole near Blythe (from project Delta Force). The data consist of digital seismograms from 14 three-component stations in a line between Mexicali and Ensenada (every 10 km) and 15 stations from the Southern California Network. The profile goes through three distinct regions: a) the Chocolate Mountains in Southern California; b) the Salton Trough in both Californias, and c) the Peninsular Ranges in Baja California, and is almost perpendicular to the general trend of the Salton Trough central axis. Vertical component seismograms at distances of 40-260 km are interpreted. The record section shows several secondary phases which are correlated and interpreted in a forward modelling scheme for time arrivals and relative amplitudes. No significant S-wave arrivals are identified. A preliminary interpretation produces a crustal depth of 22 km beneath the Chocolate Mountains and a crustal structure of P-wave velocities comprised by layers of 5.3, 5.5 and 6.2. km/s, with thicknesses of 4, 8 and 10 km, respectively. Results for the crustal structure of the Mexicali-Imperial Valley are consistent with the extensive refraction measurements made in the past; in addition, the presence of an upper mantle intrusion beneath the Valley is well resolved. Data are insufficient for determining crustal thickness in the Peninsular Ranges region. [Espanol] Se presentan los datos y la interpretacion de un perfil sismico de refraccion entre Blythe, Arizona y Ensenada, Baja California. Se utilizo como fuente una explosion subterranea realizada en un pozo cerca de Blythe como parte del proyecto Delta Force. Para obtener los datos se instalaron entre Mexicali y Ensenada 14 estaciones digitales portatiles con sismometros de tres componentes, cada 10 km, esta informacion se complemento con datos de 15 estaciones de la Red del Sur de California. El perfil atraviesa tres distintas regiones: a) Las Montanas Chocolate en el Sur de California; b) La Cuenca Salton en ambas Californias, y c) Las Sierras en Baja California, y es casi perpendicular al eje central de la Cuenca Salton. Se interpretan los sismogramas de la componente vertical para un intervalo de distancias de 40 a 260 km. Los ensamblajes muestran varias fases secundarias que fueron correlacionadas e interpretadas, se modelaron sus tiempos de recorrido y amplitudes relativas por medio de trazado de rayos asintoticos. No se identificaron llegadas claras de ondas S. Nuestra interpretacion preliminar muestra una corteza de 22 km de profundidad bajo las Montanas Chocolate con una estructura de velocidades para onda P definida por tres capas de 5.3, 5.5 y 6.2. km/s, con grosores de 4, 8 y 10 km respectivamente. Los resultados para la estructura de la corteza en el Valle Mexicali-Imperial son consistentes con los amplios estudios previamente realizados en la zona; sin embargo, se detecto la presencia de una intrusion del manto superior bajo el Valle a una profundidad de 17 km y que el Valle Mexicali-Imperial actua como una zona de generacion de ondas multiples de gran amplitud. Los datos son insuficientes para determinar con precision la estructura cortical en la region de las Sierras Peninsulares.

  16. San Jose, Costa Rica

    2007-01-01

    San Jose, capital city of Costa Rica, fills the valley between two steep mountain ranges. In this image made from data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite, visible, shortwave, and near-infrared wavelengths of light that the sensor observed have been combined to produce a false-color version of the scene in which vegetation is red, urban areas are silvery gray, water is dark blue, and clouds are white. The image was captured on February 8, 2007. San Jose is in the center of the image. The Rio Torres winds through downtown San Jose. Cartago, the much smaller colonial capital, sits in the lower right corner, while the city of Alajuela appears across the river, northwest of San Jose. The cities' manmade surfaces contrast sharply with the lushly vegetated landscape surrounding the city. Greenhouses are common in the region, and their glass roofs may be the brilliant white spots around the outer edges the cities. The long, straight runway of the Tobias Bolanos International Airport is visible as a dark line southeast of Alajuela. The landscape around the two cities shown here is rugged. Steep mountain peaks cast dark shadows across their leeward slopes. Patches of dark red vegetation on the mountains north of San Jose may be rainforest. Coffee plantations also cover the slopes of the mountains around the city. February is the dry season in Costa Rica. During the rainy season, from about April to November, clouds usually block the satellite's view of this tropical location.

  20. Detailed geochemical survey data release for the San Andres-Oscura Mountains special study area, New Mexico

    The work reported here includes field data and the results of analyses for uranium and additional elements for each sample. This special study is a follow-up to the uranium reconnaissance previously conducted by Los Alamos in the surrounding Tularosa NTMS quadrangle as part of the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). The HSSR program is part of the United States Department of Energy (DOE) National Uranium Resource Evaluation (NURE), which is designed to provide an improved estimate of the available information for industry use in the development and production of uranium resources. Each rock sample collected for this special study was crushed and the minus 100-mesh fraction was put into a prewashed 25-ml polyethylene vial and a clean 4-ml rabbit before undergoing analysis. The possibility exists of sample contamination with crusher alloys, especially in the rhyolite samples. The samples were analyzed for uranium and thorium as well as aluminum, antimony, arsenic, barium, beryllium, bismuth, cadmium, calcium, cerium, cesium, chlorine, chromium, cobalt, copper, dysprosium, europium, gold, hafnium, iron, lanthanum, lead, lithium, lutetium, magnesium, manganese, molybdenum, nickel, niobium, potassium, rubidium, samarium, scandium, selenium, silver, sodium, strontium, tantalum, terbium, tin, titanium, tungsten, vanadium, ytterbium, zinc, and zirconium. Descriptions of field and analytical methods can be found in Appendix II-A. Sample locations are plotted on Plate I. All samples were analyzed for uranium by delayed neutron counting. Other elemental concentrations in samples were determined by neutron-activation analysis, x-ray fluorescence, and arc-source emission spectrography. Analytical results for samples are reported as parts per million

    A project to recover economic amounts of oil from a very mature oil field is being conducted by Laguna Petroleum Corporation of Midland, Texas, with partial funding from a U. S. Department of Energy (DOE) grant to study shallow carbonate rock reservoirs. The objectives of the project are to use modern engineering methods to optimize oil field management and to use geological and geophysical data to recover untapped potential within the petroleum reservoirs. The integration of data and techniques from these disciplines has yielded results greater than those achievable without their cooperation. The cost of successfully accomplishing these goals is to be low enough for even small independent operators to afford. This article is a report describing accomplishments for the fiscal year 1998-1999.

His infamous photograph Piss Christ (1987 is the oft-cited example at the center of the National Endowment for the Arts controversies during the Culture Wars of the 1980s and 1990s. I return to Piss Christ as a way to expand the interpretative scope of Serrano’s early photographs, which I call “taboo icons” because of their ambiguity and ability to crisscross symbolic boundaries in the unstable space between sacred and profane, thus making his images both powerful and potentially dangerous. Building upon previous scholarship that draws connections between modern and early modern aesthetic practices, I look to the material practices of Christianity in medieval Europe characterized by a sophisticated visual culture that mixed both the physical and the spiritual. The intensifying rejection and reverence of matter resulted in divergent responses, yet the contradictory nature of matter remained central to the ideological beliefs of Christianity where the doctrines of Creation, Incarnation, and Resurrection are at its core. Serrano’s visceral photographs are emphatically material and can productively be read vis-à-vis medieval visual culture. In doing so, this reading changes the narrow perception of Serrano’s early photographs and provides an alternative understanding of his artistic project that reinserts religion into contemporary American art discourse.

  17. Promotional archipelagoes of change. Spatial analysis of Dinosauro

    During the last decades, the post industrial Latin American cities have become important economic centers in the world. Their integration into the world economy helped those cities become in the favorite places for the linking functions and activities to the world nets of commerce, productions culture, etc. These urban centers which are expanding gradually into segmented developing areas have caused an apparent space duality between the private and public activities as it can be seen though the differential access to goods and services by the society. At present, there has been an increase in cultural activities which form change promoting archipelagoes subject to several dimensions of analysis. The inequity in the distribution of economic and educational resources causes unequal ways of access to consumption of these areas of cultural production, and of goods and services, what gives place to situations of social exclusion and inclusion. To understand this fact related to money behavior, we have selected an area situated in the northwest of Cordoba capital city, in Argentina, which is a shopping mall called Dinosaurio Group. In this essay we present an exploration into the conflicts caused to the cities through the expansion of the segmented urban centers, promoters of change, and its relationship with the public and private space.

  18. Assessment of Satellite Precipitation Products in the Philippine Archipelago

    Ramos, M. D.; Tendencia, E.; Espana, K.; Sabido, J.; Bagtasa, G.

    2016-06-01

    Precipitation is the most important weather parameter in the Philippines. Made up of more than 7100 islands, the Philippine archipelago is an agricultural country that depends on rain-fed crops. Located in the western rim of the North West Pacific Ocean, this tropical island country is very vulnerable to tropical cyclones that lead to severe flooding events. Recently, satellite-based precipitation estimates have improved significantly and can serve as alternatives to ground-based observations. These data can be used to fill data gaps not only for climatic studies, but can also be utilized for disaster risk reduction and management activities. This study characterized the statistical errors of daily precipitation from four satellite-based rainfall products from (1) the Tropical Rainfall Measuring Mission (TRMM), (2) the CPC Morphing technique (CMORPH) of NOAA and (3) the Global Satellite Mapping of Precipitation (GSMAP) and (4) Precipitation Estimation from Remotely Sensed information using Artificial Neural Networks (PERSIANN). Precipitation data were compared to 52 synoptic weather stations located all over the Philippines. Results show GSMAP to have over all lower bias and CMORPH with lowest Mean Absolute Error (MAE) and Root Mean Square Error (RMSE). In addition, a dichotomous rainfall test reveals GSMAP and CMORPH have low Proportion Correct (PC) for convective and stratiform rainclouds, respectively. TRMM consistently showed high PC for almost all raincloud types. Moreover, all four satellite precipitation showed high Correct Negatives (CN) values for the north-western part of the country during the North-East monsoon and spring monsoonal transition periods.

  19. The coastal fishes and fisheries of the Socotra Archipelago, Yemen.

    Zajonz, Uwe; Lavergne, Edouard; Klaus, Rebecca; Krupp, Friedhelm; Aideed, Moteah Sheikh; Saeed, Fouad Naseeb

    2016-04-30

    The Socotra Archipelago is situated in the Gulf of Aden where tropical and "pseudo-temperate" conditions combine to create a unique marine ecosystem. The diversity, ecology, productivity and fisheries of the coastal fish assemblages are still relatively understudied and no update of the scientific knowledge existed. The islands support unique coastal and coral-associated fish assemblages in spite of the limited biogenic reef frameworks. Fish diversity is the highest among comparable Arabian eco-regions, and fish biomass productivity high too by Indian Ocean standards. The production of the once traditionally-managed small-scale fishery is severely declining and whether it is sustainable nowadays is extremely doubtful. At a time when Yemen is torn apart by a severe political and humanitarian crisis it is timely to review and update the current state of knowledge for scientists and managers, and thereby ease access to existing information, facilitating follow-on studies and evidence-based conservation and fisheries management.

  20. Factors controlling phosphorus release from sediments in coastal archipelago areas.

    Puttonen, Irma; Kohonen, Tuula; Mattila, Johanna

    2016-07-15

    In coastal archipelago areas of the northern Baltic Sea, significantly higher phosphate concentrations (6.0±4.5μmol/l, mean±SD) were measured in water samples close to the sediment surface compared with those from 1m above the seafloor (1.6±2.0μmol/l). The results indicated notable phosphate release from sediments under the bottom water oxygen concentrations of up to 250μmol/l, especially in areas that had experienced recent temporal fluctuation between oxic and hypoxic/anoxic conditions. No single factor alone was found to control the elevated PO4-P concentrations in the near-bottom water. In addition to the oxygen in the water, the contents of potentially mobile phosphorus fractions, grain-size, the organic content at the sediment surface, and the water depth were all important factors controlling the internal loading of phosphorus. The complexity of this process needs to be accounted for in assessments of the internal loading of phosphorus and in potential mitigation plans. PMID:27184132

  1. Characterisation of a basin mire in the Azores archipelago

    E. Dias

    2007-10-01

    Full Text Available The Azores archipelago in the North Atlantic is an extremely important area for biodiversity because it is rich in rare species and habitats, and almost undisturbed. The Lagoa do Madruga is a small basin mire located at 956 m a.s.l. on Santa Bárbara Mountain, Terceira Island. It is an extremely good example of a peatland type that was first discovered in 1998, and has not previously been described in the international literature. This paper provides baseline information on its flora, vegetation communities, structure and hydrology. Thirty-one plant species including eight Sphagnum species and nine endemic vascular plants have been recorded, and four plant communities are distinguished. The maximum peat depth is three metres. The mire receives flowing water from its margins and from a small stream entering at its eastern end, in addition to intercepted precipitation and fog. The accumulated water forms pools and soakways which feed other wetlands downstream. The conservation status of the mire is good, but it is subject to increasing pressure from garbage generated during maintenance operations at a nearby antenna array.

  2. Landslides density map of S. Miguel Island, Azores archipelago

    P. Valadão

    2002-01-01

    Full Text Available The Azores archipelago is located in the Atlantic Ocean and is composed of nine volcanic islands. S. Miguel, the largest one, is formed by three active, E-W trending, trachytic central volcanoes with caldera (Sete Cidades, Fogo and Furnas. Chains of basaltic cinder cones link those major volcanic structures. An inactive trachytic central volcano (Povoação and an old basaltic volcanic complex (Nordeste comprise the easternmost part of the island. Since the settlement of the island early in the 15th century, several destructive landslides triggered by catastrophic rainfall episodes, earthquakes and volcanic eruptions occurred in different areas of S. Miguel. One unique event killed thousands of people in 1522. Houses and bridges were destroyed, roads were cut, communications, water and energy supply systems became frequently disrupted and areas of fertile land were often buried by mud. Based on (1 historical documents, (2 aerial photographs and (3 field observations, landslide sites were plotted on a topographic map, in order to establish a landslide density map for the island. Data obtained showed that landslide hazard is higher on (1 the main central volcanoes where the thickness of unconsolidated pyroclastic deposits is considerable high and (2 the old basaltic volcanic complex, marked by deep gullies developed on thick sequences of lava flows. In these areas, caldera walls, fault scarps, steep valley margins and sea cliffs are potentially hazardous.

  4. Comparative phylogeography of oceanic archipelagos: Hotspots for inferences of evolutionary process

    Shaw, Kerry L.; Gillespie, Rosemary G.

    2016-01-01

    Remote island archipelagos offer superb opportunities to study the evolution of community assembly because of their relatively young and simple communities where speciation contributes to the origin and evolution of community structure. There is great potential for common phylogeographic patterns among remote archipelagos that originate through hotspot volcanism, particularly when the islands formed are spatially isolated and linearly arranged. The progression rule is characterized by a phylogeographic concordance between island age and lineage age in a species radiation. Progression is most likely to arise when a species radiation begins on an older island before the emergence of younger islands of a hotspot archipelago. In the simplest form of progression, colonization of younger islands as they emerge and offer appropriate habitat, is coincident with cladogenesis. In this paper, we review recent discoveries of the progression rule on seven hotspot archipelagos. We then discuss advantages that progression offers to the study of community assembly, and insights that community dynamics may offer toward understanding the evolution of progression. We describe results from two compelling cases of progression where the mosaic genome may offer insights into contrasting demographic histories that shed light on mechanisms of speciation and progression on remote archipelagos.

    Abstract (E: This article focuses on the relationship between the work of André Bazin and Chris Marker from the late 1940s through to the late 1950s and beyond. The division between Bazin's ŘRight Bankř affiliation with Les Cahiers du Cinéma on the one hand, and Markerřs ŘLeft Bankř allegiances on the other, is called into question here as my argument seeks to muddy the waters of their conventional ideological separation across the river Seine. Working alliteratively through Markerřs well-known talent for deft montage along with his militancy, I consider Bazinřs praise for Markerřs editing technique Ŕ in spite of famously expressing a preference elsewhere for the long take, and deep focus cinematography Ŕ and I address their political differences and convergences. Yet I also explore the rather more unexpected question of metaphysics in order to further emphasize a closer relationship between these two figures. I chart the emergence of an enduring spiritual bond between critic and filmmaker that surfaces first in Markerřs writings for the left-wing Catholic journal L’EspritViticultural zoning of Graciosa island of the Azores archipelago - Portugal

    2016-04-01

    The management and sustainability of the traditional vineyards of the Azores settled on lava field terrains is strongly affected by practical limitations of mechanization and high demand on man labor imposed by the typical micro parcel structure of the vineyards. In a recent macrozoning approach study Madruga et al (2015) showed that besides the traditional vineyards there are significant areas in some of the Azores islands whose soils, climate and physiographic characteristics indicate a potential for the development of new vineyard areas offering conditions for better management and sustainability. The objective of this study was to conduct a detailed viticultural zoning at the level of the small mapscale (smaller than 1:25,000), for the island of Graciosa where, besides the traditional lava field terroir, there are also some localized experiences of grapevine production over normal soils, offering thus some comparative information on this type of production conditions. The zoning approach for the present study was based in a geographic information system (GIS) analysis incorporating factors related to climate and topography which was then combined with the soil mapping units fulfilling the suitable criteria concerning the soil properties taken as the most relevant for viticulture, being the result a map of homogeneous environmental units. The climatic zoning examined the direct quantitative variables (precipitation, temperature, evaporation) in relation to climate index, bioclimatic and viticultural specific values. Topography (elevation, slope, aspect, orientation) was analyzed based on the tridimensional models of the islands in GIS to include the best slopes for the mechanization of the vineyard cultural operations (0-15%). Soils were analyzed based on data and soil map units as defined in the soil surveys of the Azores archipelago. The soil properties taken for the analysis and definition of the potential vineyard areas were drainage, water holding capacity

    2010-12-01

    Full Text Available Cres-Lošinj Archipelago is the largest insular traffic unit in Northern Adriatic. The archipelago consists of two large islands, Cres and Lošinj, and 27 smaller islands located among Kvarner, Kvarnerić, Rijeka Bay and open sea. From the point of view of traffic, this area gravitates mostly toward Rijeka traffic node. Traffic development of the islands was determined in the second half of the 20th century with the development of ferry traffic and road traffic on the islands. Today, the Archipelago is characterized by prominent seasonal variations of road traffic intensity due to dominant role of tourism in space valorisation. This research included partial determination of Ecological Footprint of road traffic on the islands on the basis of CO2 emission and capacity of insular surfaces to absorb CO2.The author also created a model for calculating road mileage on the islands and indirectly calculated CO2 emission. The results indicated significant seasonal variations of CO2 emission on the islands, which are closely related to tourist valorisation of space and the number of non-residential vehicles on the islands. The paper also provides the ratio between residential and non-residential vehicles on the island, which influence the emission in accordance with their energy efficiency. The research showed that the capacity of CO2 absorption on Cres-Lošinj Archipelago is approximately 40 times greater than CO2 emission from road traffic during one year.

  6. Evolution of heat transport pathways in the Indonesian Archipelago during last deglaciation

    2002-01-01

    The Indonesian Archipelago provides important heat transport pathways of the Western Pacific Warm Pool between the northern Indian Ocean and western equatorial Pacific Ocean, that exert important impacts on global climate change. This study investigated AMS 14C, ?18O, planktonic foraminifer assemblages and sedimentation rates in three piston cores collected in the Indonesian Archipelago. The results indicate that changes in the Indonesian Archipelago heat transport pathways were phase characteristic and in steps during the last deglaciation. In the deglaciation Termination IA, at about 12.5 kaBP, sea level rose rapidly in a short time period, and Makassar and Lombok straits widened suddenly for warm and fresh water from the Pacific to pour into the Java Sea and eastern Indian Ocean. During the Termination IB, about 9.5 kaBP, sea level rose rapidly again, and the South China Sea (SCS) started to connect with the Java Sea. With monsoon actions, a large amount of fresh water from the SCS shelf area flew through the Indonesian Archipelago.

    2016-01-01

    This paper presents an updated checklist of cartilaginous and bony fishes from the Revillagigedo Archipelago reefs and nearby areas (Tropical Eastern Pacific). To compile this list, we gathered data from field surveys between 1994 and 2015, from an exhaustive literature review, and by consulting museum collections and databases. With these records we estimated the completeness of the local fish inventory using four non-parametric rarefaction methods. We report a total of 389 species in 102 families; 235 of these are reef fish that occur in the Eastern but also in the Central Pacific, and 13 species were identified as endemic to the archipelago. A non-parametric statistical model predicts that the expected number of reef fish present at Revillagigedo should be 244.3 ± 3.2 species, which is 9 species more than the observed richness, and this difference was statistically significant (p = 0.02). That predictive model estimates that about 96% of the total richness of reef fish from the archipelago is known. Comparisons of the completeness of the inventory at Revillagigedo to that reported for the fish fauna of the Eastern Pacific and worldwide, showed that the quality of the sampling effort is remarkably high, in spite of the geographic isolation of the archipelago.

    The COPERNICUS EMS Risk & Recovery Mapping (RRM) activity offers services to support efficient design and implementation of mitigation measures and recovery planning based on EO data exploitation. The Azores Archipelagos case was realized in the context of the FWC 259811 Copernicus EMS RRM, and provides potential impact information for a number of natural disasters. The analysis identified population and assets at risk (infrastructures and environment). The risk assessment was based on hazard and vulnerability of structural elements, road network characteristics, etc. Integration of different hazards and risks was accounted in establishing the necessary first response/ first aid infrastructure. EO data (Pleiades and WV-2), were used to establish a detailed background information, common for the assessment of the whole of the risks. A qualitative Flood hazard level was established, through a "Flood Susceptibility Index" that accounts for upstream drainage area and local slope along the drainage network (Manfreda et al. 2014). Indicators, representing different vulnerability typologies, were accounted for. The risk was established through intersecting hazard and vulnerability (risk- specific lookup table). Probabilistic seismic hazards maps (PGA) were obtained by applying the Cornell (1968) methodology as implemented in CRISIS2007 (Ordaz et al. 2007). The approach relied on the identification of potential sources, the assessment of earthquake recurrence and magnitude distribution, the selection of ground motion model, and the mathematical model to calculate seismic hazard. Lava eruption areas and a volcanic activity related coefficient were established through available historical data. Lava flow paths and their convergence were estimated through applying a cellular, automata based, Lava Flow Hazard numerical model (Gestur Leó Gislason, 2013).

    Anne Boissière

    2011-05-01

    Full Text Available André Schaeffner (1895-1980, auteur du grand ouvrage Origine des instruments de musique paru en 1936, propose une réflexion sur l’instrument de musique qui est loin d’être confinée au seul champ de l’ethnologie. La considération de la musique de son temps, notamment en l’œuvre de Stravinsky, la méditation sur l’origine du théâtre et sur la tragédie, avec Nietzsche, contribuent à forger une conception de l’instrument qui est inséparable d’une philosophie de la musique. En explorant le thème central des « origines corporelles » de la musique, cet article présente trois aspects principaux au vu desquels André Schaeffner s’avère problématiser le statut de l’instrument en relation avec le corps sonore et rythmicien : le refus du dualisme entre la voix et l’instrument, le refus d’une origine manuelle des instruments, enfin l’idée d’une organologie du théâtre.Author of the classic study Origine des instruments de musique published in 1936, André Schaeffner (1895-1980 offers a reflection upon musical instruments which is a far cry from remaining within the confines of pure ethnology. Pondering the music of his own era, especially in the work of Stravinsky, as well as meditating over the origin of theatre and, following Nietzsche, over tragedy contributes to bringing about a conception of the instrument which cannot possibly be separated from a philosophy of music.  This article, as it explores the central topic of music’s « corporeal origins », presents three principal aspects in the light of which André Schaeffner is shown to thematize the status of the instrument as linked to the body sonorous and rhythmic : first, by rejecting any kind of voice-instrument dualism ; secondly, by refuting claims as to a supposedly manual origin of instruments, leading finally up to the idea of an organology of theatre.

A poem to the vaccine was written by Andres Bello, the first rector of the University of Chile, then in Venezuela (1804). The expedition reached Chile in 1807, led by Dr Julián Grajales. This expedition was the most important medical act in the history of the Spanish colonies. PMID:1844782

  7. Floristic species list of the archipelago of Jardines de la Reina, Cuba

    Carlos J. Acevedo

    2013-09-01

    Full Text Available The floristic inventories contribute directly to knowledge of plant resources of a region. In order to inventory the vascular plant species in the Jardines de la Reina archipelago, field visits were organized and literature review. The study area was represented by 113 infrageneric taxa, 97 genera and 40 families, the keys Anclitas, Grande, Caguamas, Algodón Grande and Caballones possess the higher taxonomic richest. Endemism was low (4,5% and alien plant species represent the 8%. The flora of the archipelago was cha-racterized by high representation of life forms shrubbery and herbaceous, with a predominance of elements neotropical and neotropical-holarctic. The sandy coastal vegetation and coastal xeromorphic scrub exhibited the highest values of specific richness.

  15. Characterization of mangrove forest types based on ALOS-PALSAR in overall Indonesian archipelago

    Indonesia has largest mangrove forest in the world, total area around 3.5 million ha or 17% – 23% from mangrove forest in the world. Mangrove forest provides products and services, such as carbon balance of the coastal zone. Mapping and monitoring biomass of mangrove is very important but field survey of mangrove biomass and productivity in overall Indonesia is very difficult. Global-scale mosaics with HH and HV backscatter of Advanced Land Observing Satellite (ALOS) Phased Array L-band Synthetic Aperture Radar (PALSAR) which is 50-m spatial resolution has been generated. This image available for identification and monitoring mangrove forest. The Objective of this research to investigate characterization of mangrove forest types based on ALOS-PALSAR in overall Indonesian archipelago. Methodology consists of collecting ALOS-PALSAR image for overall Indonesian archipelago, preprocessing and mosaicking, collecting region of interest of mangrove forest, plotting, ground survey, characterization and classification. The result of this research has showed characterization of mangrove forest types based on ALOS-PALSAR. Indonesian mangrove forest types has HH value around -10 dB until -7 dB and HV value around -17 dB until -13 dB. Higher of HH and HV backscatters value indicated higher of level biomass. Based on scatter plot of HH and HV, Indonesian mangrove forest can be classified in three level biomass. Generally level biomass of mangrove forest in Indonesia archipelago is moderate

  16. Climate change influenced female population sizes through time across the Indonesian archipelago.

    Guillot, Elsa G; Tumonggor, Meryanne K; Lansing, J Stephen; Sudoyo, Herawati; Cox, Murray P

    2013-01-01

    Lying at the crossroads of Asia and the Pacific world, the Indonesian archipelago hosts one of the world's richest accumulations of cultural, linguistic, and genetic variation. While the role of human migration into and around the archipelago is now known in some detail, other aspects of Indonesia's complex history are less understood. Here, we focus on population size changes from the first settlement of Indonesia nearly 50 kya up to the historic era. We reconstructed the past effective population sizes of Indonesian women using mitochondrial DNA sequences from 2,104 individuals in 55 village communities on four islands spanning the Indonesian archipelago (Bali, Flores, Sumba, and Timor). We found little evidence for large fluctuations in effective population size. Most communities grew slowly during the late Pleistocene, peaked 15-20 kya, and subsequently declined slowly into the Holocene. This unexpected pattern may reflect population declines caused by the flooding of lowland hunter/gatherer habitat during sea-level rises following the last glacial maximum. PMID:24297223

  18. Nest-density distribution patterns in a yellow-legged gull archipelago colony

    Vidal, Eric; Roche, Philip; Bonnet, Véronique; Tatoni, Thierry

    2001-12-01

    The nest density distribution of yellow-legged gulls Larus cachinnans was investigated on the large Marseille archipelago colony (south-east France) which houses c. 18 000 breeding pairs. The study was performed at two investigation scales, including both mean nesting density on the nine study islands and density distribution within 171 sampling plots. The mean nesting density on each island was negatively correlated with island surface area and with the distance from the initial colony location (south-east end of the archipelago). No significant correlation was found with the other island parameters analysed (maximum elevation, shape index and distance from continent). A partial least squares regression performed between denstiy data from 171 500 m 2 sampling plots and environmental variables showed that the mostly explaining factors were island isolation and percentage of rocks in the plots (positive correlation), and distance of the island from the south-east end of the archipelago, island area, distance from plot to seaside and percentage of stone in the plots (negative correlation). Thus in our case, vegetation parameters (cover and height) were not influencial factors in nest density distribution.

  19. Projected polar bear sea ice habitat in the Canadian Arctic Archipelago.

    Stephen G Hamilton

    Full Text Available Sea ice across the Arctic is declining and altering physical characteristics of marine ecosystems. Polar bears (Ursus maritimus have been identified as vulnerable to changes in sea ice conditions. We use sea ice projections for the Canadian Arctic Archipelago from 2006 - 2100 to gain insight into the conservation challenges for polar bears with respect to habitat loss using metrics developed from polar bear energetics modeling.Shifts away from multiyear ice to annual ice cover throughout the region, as well as lengthening ice-free periods, may become critical for polar bears before the end of the 21st century with projected warming. Each polar bear population in the Archipelago may undergo 2-5 months of ice-free conditions, where no such conditions exist presently. We identify spatially and temporally explicit ice-free periods that extend beyond what polar bears require for nutritional and reproductive demands.Under business-as-usual climate projections, polar bears may face starvation and reproductive failure across the entire Archipelago by the year 2100.

  20. Comparing the two Greek archipelagos plant species diversity and endemism patterns highlight the importance of isolation and precipitation as biodiversity drivers

    Background Greece has two island archipelagos, the Aegean and the Ionian, which host a rich array of plants and wildlife, particularly endemic and threatened plant species. Despite the long history of island biogeographic studies in the Aegean, similar studies in the Ionian remain limited, with the two island archipelagos rarely being compared. Results The Aegean and Ionian archipelagos share many features, especially regarding total plant diversity, but exhibit different patterns of endemism...

  1. Lipid sorting revealed by SANS

    We have investigated the lipid sorting in a binary small unilamellar vesicle (SUV) composed of cone-shaped (1,2-dihexanoyl-sn-glycero-3-phosphocholine: DHPC) and cylinder-shaped (1,2-dipalmitoyl-sn-glycero-3-phosphocholine: DPPC) lipids. In order to reveal the lipid sorting we adopted a contrast matching technique of small angle neutron scattering (SANS), which extracts the distribution of deuterated lipids in the bilayer quantitatively. The SANS profile of deuterated SUVs at the contrast matching condition showed a characteristic scattering profile, indicating an asymmetric distribution of cone-shaped lipids in the bilayer. The fitting of the observed SANS profile revealed that most DHPC molecules are localized in the outer leaflet, which supports that the shape of the lipid is strongly coupled with the membrane curvature. We compared the obtained asymmetric distribution of the cone-shaped lipids in the bilayer with the theoretical prediction based on the curvature energy model. (author)

  2. Marketing San Juan Basin gas

    Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

  3. Structure of microemulsions by SANS

    Small-angle neutron scattering (SANS) has been used to determine the structure of microemulsions in the system hydrocarbon-water-sodium di-ethylhexylsulfosuccinate (AOT). SANS spectra taken in a deuterated solvent showed a perfect Guinier fit with a radius of gyration of 15A regardless of the amount of AOT from 0.1 to 5% present. By varying the proportions of deuterated and undeuterated solvent to vary the contrast between the micelles and the solvent, it is concluded that the micelles are basically monodispersed spherical aggregations of 22 AOT molecules

    2015-03-01

    Full Text Available Detailed aerosol chemical predictions by a carefully designed model system (i.e. PMCAMx, WRF, GEOS-CHEM, along with airborne and ground-based observations, are presented and analyzed over a wide domain covering the Aegean Archipelago. The studied period is ten successive days during the summer of 2011, characterized by the most frequent prevailing wind conditions (Etesian regime. The submicron aerosol load in the lower troposphere above the Archipelago (< 2.2 km altitude is homogenously enriched in sulfate (average modeled and measured submicron sulfate of 5.5 and 5.8 μg m−3, respectively, followed by organics (2.3 and 4.4 μg m−3 and ammonium (1.5 and 1.7 μg m−3. Aerosol concentrations smoothly decline aloft, reaching lower values (< 1 μg m−3 above 4.2 km altitude. Model performance is found good (according the selected evaluation criteria for sulfate, ammonium, chloride, elemental carbon, organic carbon and total PM10 mass concentration, indicating a satisfactory representation of the aerosol chemistry and precursors. Higher model discrepancies are confined to the highest (e.g. peak sulfate values and lowest ends (e.g. nitrate of the airborne aerosol mass size distribution, as well as in airborne organic concentrations (model underestimation around 50%. The latter is most probably related to the intense fire activity upwind the Archipelago (i.e. Balkan area and Black Sea coastline, which is not represented in the current model application. Overall, the model system shows the best agreement with observations under strong northeastern winds over the Archipelago and up to 2.2 km altitude. The activation of the chemical ageing of biogenic particles is suggested to be used for the aerosol chemistry module, when treating organics in a sufficient nitrogen and sulfate-rich environment, such as that over the Aegean basin. More than 70% of the predicted aerosol mass over the Aegean Archipelago during a representative Etesian episode is

  14. ASTER Flyby of San Francisco

    2002-01-01

    The Advanced Spaceborne Thermal Emission and Reflection radiometer, ASTER, is an international project: the instrument was supplied by Japan's Ministry of International Trade and Industry. A joint US/Japan science team developed algorithms for science data products, and is validating instrument performance. With its 14 spectral bands, extremely high spatial resolution, and 15 meter along-track stereo capability, ASTER is the zoom lens of the Terra satellite. The primary mission goals are to characterize the Earth's surface; and to monitor dynamic events and processes that influence habitability at human scales. ASTER's monitoring and mapping capabilities are illustrated by this series of images of the San Francisco area. The visible and near infrared image reveals suspended sediment in the bays, vegetation health, and details of the urban environment. Flying over San Francisco (3.2MB) (high-res (18.3MB)), we see the downtown, and shadows of the large buildings. Past the Golden Gate Bridge and Alcatraz Island, we cross San Pablo Bay and enter Suisun Bay. Turning south, we fly over the Berkeley and Oakland Hills. Large salt evaporation ponds come into view at the south end of San Francisco Bay. We turn northward, and approach San Francisco Airport. Rather than landing and ending our flight, we see this is as only the beginning of a 6 year mission to better understand the habitability of the world on which we live.

  15. Subtidal reef fish and macrobenthic community structure at the temperate Juan Fernández Archipelago, Chile

    Alejandro Pérez-Matus

    2014-10-01

    Full Text Available The Juan Fernández Archipelago (33°37'S, 78°51'W, an isolated group of islands 650 km west of continental Chile, has a high degree of endemism in its marine biota. Despite numerous scientific expeditions to these islands that have identified this high endemism, few studies have attempted to identify patterns of community structure in subtidal habitats. Using visual census, we surveyed fish and habitat associations at five sites located at two of the three islands of the archipelago. Given the isolation of the archipelago we asked: What is the composition of the reef fish fauna at these isolated islands? What habitats dominate subtidal environments? What influences the abundances of reef fishes? Our analysis confirms that fish communities at the archipielago are dominated by endemic species. The ichthyofauna is comprised of a mixture of subtropical and temperate taxa, with greater similarity to western than eastern South Pacific fauna. We identified different fish assemblages at wave-exposed and wave-sheltered sites. Brown and red macroalgae were correlated with the abundances of some reef fishes. Four broad trophic categories of reef fishes were present at the archipelago, with invertebrate consumers dominating abundance. To our knowledge, this is the first attempt to quantify patterns of community structure in subtidal environments at the Juan Fernández Archipelago.

  20. The interior capture of life. Le Corbusier and André Malraux

    Ana Sofía Pereira da Silva

    2016-05-01

    Writings from both authors and architectural projects from Le Corbusier –  Mundial Museum, Mundaneum and Museum of Unlimited Growth- will be observed in order to map the existent affinities between the two authors. However, life’s pragmatic circumstances often oppose what uses to be in accordance. André Malraux’s classification of the Villa Savoye, while he was  Minister of the Cultural Affairs, aimed to save one of Le Corbusier’s  masterpieces. Nevertheless, this action banned the architect the possibility to transform the Villa Savoye into a new program (in a first approach and, finally, excluded him the possibility of authorship of the rehabilitation project, which was subsequently entrusted to an architect working in the National Monuments bureau. This suspected moment of friction between the two authors shall be motive of observation.

  1. Resonant extended states in driven quasiperiodic lattices: Aubry-Andre localization by design

    Morales-Molina, L.; Doerner, E.; Danieli, C.; Flach, S.

    2014-10-01

    We consider a quasiperiodic Aubry-Andre (AA) model and add a weak time-space-periodic perturbation. The undriven AA model is chosen to be well in the localized regime. The driving term controls the effective number of propagation channels. For a spatial resonance which reduces the reciprocal space dynamics to an effective one-dimensional two-leg ladder, the ac perturbation resonantly couples certain groups of localized eigenstates of the undriven AA model and turns them into extended ones. Slight detuning of the spatial and temporal frequencies off resonance returns these states into localized ones. We analyze the details of the resonant extended eigenstates using Floquet representations. In particular, we find that their size grows linearly with the system size. Initial wave packets overlap with resonant extended eigenstates and lead to ballistic spreading.

  3. Feeding Habits of Introduced Black Rats, Rattus rattus, in Nesting Colonies of Galapagos Petrel on San Cristobal Island, Galapagos.

    Marjorie Riofrío-Lazo

    Full Text Available Introduced rodents are responsible for ecosystem changes in islands around the world. In the Galapagos archipelago, their effects on the native flora and fauna are adverse, including the extinction of endemic rodents in some islands and the reduction in the reproductive success of the Galapagos petrel (Pterodroma phaeopygia in its nesting zones. Understanding the feeding behavior of introduced rodents and their trophic interactions with native and non-native species on islands, can assist in the design of management strategies and conservation plans of invasive and endemic species respectively. Four petrel nesting colonies were monitored during June 2013 on San Cristóbal Island (El Plátano, El Junco, San Joaquín, and La Comuna. The feeding habits of black rats were evaluated by analyzing stomach contents and stable isotopes in hair. Three species of introduced rodents were captured. R. rattus was the most abundant at all sites (n=43, capture success (CS = 55.8%, followed by the house mouse, Mus musculus (n = 17, CS = 37.8%, and the Norwegian rat, R. norvegicus (n = 4, CS = 4.5%, captured only at La Comuna. The omnivorous black rat ate mostly plants (98% and arthropods (2%. Intact seeds of Miconia robinsoniana were the main food at all sites (relative abundance=72.1%, present in 95% of the analyzed stomachs, showing the black rats' possible role in the archipelago as endemic seed dispersers. There was no evidence of petrel's intake; however, its possible consumption is not discarded at all. The δ15N and δ13C analysis corroborated the primarily herbivorous diet of black rats. The isotopic signatures of the three rodent species reflect the inter- and intra-specific differential use of food resources. Black rat showed a wider diet in La Comuna, which was related to a lower availability of its primary prey and its ability to adapt to the available resources in its habitat.

  4. The lost Adventure Archipelago (Sicilian Channel, Mediterranean Sea): Morpho-bathymetry and Late Quaternary palaeogeographic evolution

    Civile, Dario; Lodolo, Emanuele; Zecchin, Massimo; Ben-Avraham, Zvi; Baradello, Luca; Accettella, Daniela; Cova, Andrea; Caffau, Mauro

    2015-02-01

    The rise in sea level following the Last Glacial Maximum (LGM) radically altered pre-existing geography, pushing back the former shorelines. The effect of this eustatic change was particularly intense and dramatic in flat lands and shelves, such as the Sicilian Channel. High-resolution bathymetric maps and Chirp seismic profiles analyzed in this study show that the Sicilian Channel, now lying at depths rarely exceeding 150 m, has emerged several times during its geological history. The last emergence was during the Early Holocene, when kilometre-sized islands punctuated the north-western sector of the Sicilian Channel, the Adventure Plateau, forming a broad archipelago. Many of these islands, now located in water ranging in depth from - 10 to - 40 m, are composed of highly deformed Neogene sedimentary rocks (Talbot, Ante-Talbot, Nereo, and Pantelleria Vecchia banks), while others represent submarine Pleistocene volcanic edifices (Galatea, Anfitrite and Tetide banks). Sedimentary cover in all of these banks is virtually absent. High-resolution seismic profiles allowed the identification of post-LGM morphological markers associated with the marine transgression, some of which are characterized by melt water-pulses, as demonstrated by the presence of specific and distinct erosional features. Combining swath bathymetric data with the seismic profiles, we have generated two palaeogeographic maps of the former Adventure Archipelago at two specific time frames: (1) at the end of the Younger Dryas stadial (11,500 yr B.P., corresponding to a former sea level of - 60 m), and (2) at the end of the melt-water pulse 1B (11,200 yr B.P., corresponding to a former sea level of - 42 m). Maps clearly show that in just 300 years the geography of the archipelago has changed dramatically, so much so that some islands have disappeared and some have decreased by more than 80% of their pre-Younger Dryas size.

  5. Microbiological and mycological beach sand quality in a volcanic environment: Madeira archipelago, Portugal

    Madeira forms a mid-Atlantic volcanic archipelago, whose economy is largely dependent on tourism. There, one can encounter different types of sand beach: natural basaltic, natural calcareous and artificial calcareous. Microbiological and mycological quality of the sand was analyzed in two different years. Bacterial indicators were detected in higher number in 2010 (36.7% of the samples) than in 2011 (9.1%). Mycological indicators were detected in a similar percentage of samples in 2010 (68.3%) and 2011 (75%), even though the total number of colonies detected in 2010 was much higher (827 in 41 samples) than in 2011 (427 in 66 samples). Enterococci and potentially pathogenic and allergenic fungi (particularly Penicillium sp.) were the most common indicators detected in both years. Candida sp. yeast was also commonly detected in the samples. The analysis of the 3rd quartile and maximum numbers of all indicators in samples showed that artificial beaches tend to be more contaminated than the natural ones. However, a significant difference between the variables was lacking. More monitoring data (number of bathers, sea birds, radiation intensity variation, and a greater number of samples) should be collected in order to confirm if these differences are significant. In general, the sand quality in the archipelago's beaches was good. As the sand may be a vector of diseases, an international common set of indicators and values and a compatible methodologies for assessing sand contamination, should be defined, in order to provide the bather's with an indication of beach sand quality, rather than only the water. - Highlights: • Microbial indicators were studied in the beach sands of Madeira archipelago. • Differences between years may be attributed to extreme weather. • Sand of artificial beaches has higher levels of microbial contamination. • Microbial analysis of the sand showed that the beaches have mainly good quality

  7. Seismicity pattern changes before the M = 4.8 Aeolian Archipelago (Italy) earthquake of August 16, 2010.

    Gambino, Salvatore; Laudani, Antonino; Mangiagli, Salvatore

    2014-01-01

    We investigated the seismicity patterns associated with an M = 4.8 earthquake recorded in the Aeolian Archipelago on 16, August, 2010, by means of the region-time-length (RTL) algorithm. This earthquake triggered landslides at Lipari; a rock fall on the flanks of the Vulcano, Lipari, and Salina islands, and some damages to the village of Lipari. The RTL algorithm is widely used for investigating precursory seismicity changes before large and moderate earthquakes. We examined both the spatial and temporal characteristics of seismicity changes in the Aeolian Archipelago region before the M = 4.8 earthquake. The results obtained reveal 6-7 months of seismic quiescence which started about 15 months before the earthquake. The spatial distribution shows an extensive area characterized by seismic quiescence that suggests a relationship between quiescence and the Aeolian Archipelago regional tectonics. PMID:24511288

  8. Number of endemic and native plant species in the Galapagos Archipelago in relation to geographical parameters

    2002-01-01

    By simple and multiple regression analyses we investigate updated species numbers of endemic and native vascular plants and seed plants in the Galapagos Archipelago in relation to geographical parameters. We find that the best models to describe species numbers are regression models with log......-transformed species numbers as dependent and log-transformed modified area (i.e. area not covered with barren lava) as an independent variable. This holds both for total species number, for native species number, for endemic species number and for total number of seed plants as well as number of endemic seed plants...

  9. Velocity selector for SANS spectrometer

    Mechanical velocity selector, designed firstly at the beginning of the neutron age (the end of 40-th - 50-th, see and references herein) are nowadays of wide use at SANS spectrometers on steady state neutron sources. The present report is devoted to the description of the construction and parameters of the selector, designed for SANS spectrometer at the 1 MW research reactor (URGN, Draria, Algeria). The design of selector provides high transmission (more then 90%) and wavelength resolution of Δλ,/λ ∼ 14%, allowing the neutron wavelength to be selected between 4 A and 10 A. The rotor of selector is an aluminium cylinder rotating in a vacuum jacket around the horizontal axis. The rotor slits of helical shape are formed by absorbing plates with thickness 0.5 mm and made of Gd (10%)-Al alloy. (author)

  11. Sintered materials studied by SANS

    Complete text of publication follows. The small angle scattering of compacted and sintered single phase materials with open or closed porosity can be described by the two phase model. During sintering, the decrease of pore volume is accompanied with decreasing internal surface measured by SANS [1]. Such investigation can be extended to the field of technically relevant multiphase materials as well, e.g. doped tunsten, SiN ceramics and WC-Co composite made from nano-crystalline powder. The deformation of remaining porosity after sintering can be monitored by 2D anisotropy of SANS distribution as the sintered body is processed through several steps of thermomechanical treatment. The elongation of pores or stable bubbles, e.g. K gas filled bubbles in doped W [2], follows the macroscopic deformation of the body. Heat treatment, however, causes spheroidization with vanishing SANS anisotropy. Our investigation using the isointensity contour map method allows establishing a new description of mechanisms of thermomechanical processing. (author) [1] O. Blaschko, R. Glas, G. Krexner and P.

  12. The role of the Azores Archipelago in capturing and retaining incoming particles

    Sala, Iria; Harrison, Cheryl S.; Caldeira, Rui M. A.

    2016-02-01

    The capacity of the Azores Archipelago to capture and retain incoming particles and organisms that are drifting with the oceanic currents was the main focus of this study. Using the Hybrid Coordinate Ocean Model coupled with the Connectivity Modeling System (an offline Lagrangian tool) a series of experiments were conducted to determine: i) the origin of the particles that reach the archipelago, ii) the capacity of each island sub-group to retain incoming particles and organisms, as well as the iii) oceanographic phenomena that lead to their transport and retention. The Gulf Stream (GS) and the westward propagating eddy corridors were identified as the main transport pathways affecting the Azores region. Eddy Kinetic Energy from altimetry data and Lyapunov exponent analysis suggest that eddies and filaments are the main delivery mechanisms. In the upper mixed layer, the GS and its associated eddies are a predominant regional oceanographic feature injecting particles from the north and west boundaries toward the Azores. The capacity to capture particles of each island sub-group was directly proportional to their size, while the retention time within the Azores region increased with depth, associated with the decrease in velocity of the intermediate water currents. This study opens new prospects to understand transport in the Mid-Atlantic (Azores) region and the islands' role in marine colonization, dispersal, fisheries recruitment and speciation.

  13. Maximum Rain-Rate Evaluations in Aegean Archipelagos Hellas for Rain Attenuation Modeling at Microwave Frequencies

    Evangelia Karagianni

    2016-04-01

    Full Text Available By utilizing meteorological data such as relative humidity, temperature, pressure, rain rate and precipitation duration at eight (8 stations in Aegean Archipelagos from six recent years (2007 – 2012, the effect of the weather on Electromagnetic wave propagation is studied. The EM wave propagation characteristics depend on atmospheric refractivity and consequently on Rain-Rate which vary in time and space randomly. Therefore the statistics of radio refractivity, Rain-Rate and related propagation effects are of main interest. This work investigates the maximum value of rain rate in monthly rainfall records, for a 5 min interval comparing it with different values of integration time as well as different percentages of time. The main goal is to determine the attenuation level for microwave links based on local rainfall data for various sites in Greece (L-zone, namely Aegean Archipelagos, with a view on improved accuracy as compared with more generic zone data available. A measurement of rain attenuation for a link in the S-band has been carried out and the data compared with prediction based on the standard ITU-R method.

  14. Hybridization occurs between Drosophila simulans and D. sechellia in the Seychelles archipelago.

    Matute, D R; Ayroles, J F

    2014-06-01

    Drosophila simulans and D. sechellia are sister species that serve as a model to study the evolution of reproductive isolation. While D. simulans is a human commensal that has spread all over the world, D. sechellia is restricted to the Seychelles archipelago and is found to breed exclusively on the toxic fruit of Morinda citrifolia. We surveyed the relative frequency of males from these two species in a variety of substrates found on five islands of the Seychelles archipelago. We sampled different fruits and found that putative D. simulans can be found in a variety of substrates, including, surprisingly, M. citrifolia. Putative D. sechellia was found preferentially on M. citrifolia fruits, but a small proportion was found in other substrates. Our survey also shows the existence of putative hybrid males in areas where D. simulans is present in Seychelles. The results from this field survey support the hypothesis of current interbreeding between these species in the central islands of Seychelles and open the possibility for fine measurements of admixture between these two Drosophila species to be made.

  15. Biogeography of planktonic and coral-associated microorganisms across the Hawaiian Archipelago.

    Salerno, Jennifer L; Bowen, Brian W; Rappé, Michael S

    2016-08-01

    Factors driving the distribution of marine microorganisms are widely debated and poorly understood. Recent studies show that free-living marine microbes exhibit geographical patterns indicative of limited dispersal. In contrast, host-associated microbes face a different set of dispersal challenges, and hosts may function as habitat 'islands' for resident microbial populations. Here, we examine the biogeographical distributions of planktonic and adjacent coral-associated bacterial communities across the Hawaiian Archipelago, Johnston Atoll (∼1400 km southwest of Hawaii) and American Samoa in the Pacific Ocean and investigate the potential underlying processes driving observed patterns. Statistical analyses of bacterial community structure, determined using a small-subunit ribosomal RNA gene-based approach, showed that bacterioplankton and coral-associated bacterial communities were distinct, and correlated with geographical distance between sites. In addition, biogeographical patterns of bacterial associates paralleled those of their host coral Porites lobata, highlighting the specificity of these associations and the impact that host dispersal may have on bacterial biogeography. Planktonic and coral-associated bacterial communities from distant Johnston Atoll were shown to be connected with communities from the center of the Hawaiian Archipelago, a pattern previously observed in fish and invertebrates. No significant correlations were detected with habitat type, temperature or depth. However, non-distance-based geographical groupings were detected, indicating that, in addition to dispersal, unidentified environmental factors also affected the distributions of bacterial communities investigated here.

  16. Present situation and future prospects of electricity generation in Aegean Archipelago islands

    The Aegean Archipelago is a remote Hellenic area, including several hundreds of scattered islands of various sizes. In these islands more than 600,000 people are living mainly in small remote communities. The main economical activities of the islanders are apart from tourism, seafaring, fishery, agriculture and stock farming. One of the major problems of the area is the insufficient infrastructure, strongly related with the absence of an integrated and cost-effective electrification plan. In this context, the present work is concentrated on analyzing the present situation and demonstrating the future prospects of electricity generation in the Aegean Archipelago islands. For this purpose, one should first investigate the time evolution of the corresponding electricity generation parameters (i.e. annual electricity consumption, peak power demand, capacity factor, specific fuel consumption) for the last 30 years. Subsequently, the corresponding diesel and heavy-oil consumption along with the electricity production cost for every specific autonomous power station of the area are investigated. Special attention is paid in order to estimate the contribution of renewable energy sources (RES) in the energy balance of each island. Finally, an attempt is made to describe in brief the most realistic electricity production solutions available, including the operation of hybrid RES-based power plants in collaboration with appropriate energy storage facilities. Additionally, the idea of connecting the islands of the area with the mainland and interconnecting them is also taken into consideration

  17. Shallow-water stenopodidean and caridean shrimps from Abrolhos Archipelago, Brazil: new records and updated checklist.

    Soledade, Guidomar O; Fonseca, Mytalle S; Almeida, Alexandre O

    2015-01-01

    This study deals with a recent collection of stenopodidean and caridean shrimps made in the Abrolhos Archipelago, Bahia, Brazil, in July and August 2013. Sampling was carried out in the vicinity of Ilha de Santa Bárbara (17°57'49"S 38°41'53"W). Specimens were obtained by hand or using small hand nets in tide pools or under rocks in the intertidal zone. Part of the material was collected by scuba diving in the shallow subtidal, to a maximum depth of 11 m. We obtained a total of 18 species, 12 of which are reported for the first time for the Abrolhos and 4 as new records for the state of Bahia. The distributions of Microprosthema semilaeve (von Martens, 1872), Typton gnathophylloides Holthuis, 1951, Alpheus verrilli (Schmitt, 1924) and Alpheopsis cf. trigona (Rathbun, 1901) are extended from their previously known ranges. The occurrence of Automate cf. rectifrons Chace, 1972 on the Brazilian coast is confirmed. We thus provide an updated checklist of stenopodidean (2 species) and caridean (29 species) shrimps from the Abrolhos Archipelago, incorporating and critically evaluating previous records.  PMID:25661021

  18. Exchanges of volume, heat and freshwater through the Canadian Arctic Archipelago: a numerical study.

    Grivault, Nathan; Hu, Xianmin; Myers, Paul G.

    2016-04-01

    The Canadian Arctic Archipelago (CAA) is a tangle of shallow basins interlinked by narrow straits. It is the main pathway of liquid freshwater from the Arctic Ocean to North Atlantic. It also receives runoff from the Mackenzie River and the glaciers of the different islands that composes the archipelago. This study is based on a set of numerical experiments using a regional configuration of the coupled ocean/sea-ice general circulation model NEMO. We consider a long-term hindcast (1958-2014) as well as the more recent period (2002-2014) using high resolution inter-annual forcing from Environment Canada. We used an improved mapping of runoff to ensure correct amounts of freshwater are added to the system. We evaluate the flow pathways through the CAA, as well as the transport of volume, heat and freshwater. Results are evaluated against observational sections. We also look at the variability and the dynamics driving it. Passive tracers are used to complement the analysis.

  1. A multiproxy reconstruction of NAO evolution in the Azores archipelago since 1350 AD

    2014-05-01

    The North Atlantic Oscillation (NAO) is the main atmospheric circulation pattern affecting climate variability in the Northern Hemisphere, having a major impact on both marine and terrestrial ecosystems. Instrumental records of the NAO are relatively short, and therefore paleoenvironmental multiproxy approaches become fundamental to better understand its behaviour for longer scale periods. The NAO is often defined as a large-scale meridional oscillation dipole of air pressure between the Azores High and the Iceland Low. Some of the NAO definitions include the use of sea level pressure from Ponta Delgada station in Azores, and thus any NAO reconstruction would gain in robustness if it includes paleoenvironmental information from this archipelago located at the southern end of the meridional dipole that characterizes the NAO pattern. However, to the best of our knowledge, very few historical and long-term reconstructions have been conducted in the Azores Islands. We present a ca. 600-year-long multiproxy reconstruction of the NAO evolution based on facies analysis, X-ray diffraction (XRD), X-ray fluorescence (XRF) core scanning, elemental and isotope geochemistry on bulk organic matter and the preliminary study of diatom and chironomid content from the sedimentary record of Lake Empadadas (37° 49' N - 25° 44' W, Azores Archipelago, Portugal). The precipitation regime in Azores Archipelago (i.e. intra and inter-annual variability) is clearly influenced by the NAO index, thus periods with dominant positive NAO index values (NAO+) are usually characterized by low winter precipitation in the Azores. Conversely, negative NAO phases (NAO-) induce high winter precipitation in the archipelago. These patterns suggest that past (winter) precipitation changes on the Azores may be partially used as a proxy for NAO changes, and thus a proxy for more large-scale changes in the North Atlantic region. According to this multiproxy characterization of the Lake Empadadas sediments

    Eighteenth century Spain witnessed a revaluation of the Hippocratic works as a result of the growing criticism of the Galenism dominant in the Spanish University of the time. Probably the most important author in this reformist trend was Andrès Piquer y Arrufat (1711-1772), eclectic philosopher, university professor and doctor to the Kings Fernando VI and Carlos III. His desire to transform medical university instruction following Hippocrates' rules led him to make some of the first Hippocrat...

  10. SANS from interpenetrating polymer networks

    Full text: Interpenetrating polymer networks (IPNs) have been formed by combining two polymeric systems in order to gain enhanced material properties. IPNs are a combination of two or more polymers in network form with one network polymerised and/or crosslinked in the immediate presence of the other(s).1 IPNs allow better blending of two or more crosslinked networks. In this study two sets of IPNs were produced and their microstructure studied using a variety of techniques including small angle neutron scattering (SANS). The first system combined a glassy polymer (polystyrene) with an elastomeric polymer (SBS) with the glassy polymer predominating, to give a high impact plastic. The second set of IPNs contained epichlorohydrin (CO) and nitrile rubber (NBR), and was formed in order to produce novel materials with enhanced chemical and gas barrier properties. In both cases if the phase mixing is optimised the probability of controlled morphologies and synergistic behaviour is increased. The PS/SBS IPNs were prepared using sequential polymerisation. The primary SBS network was thermally crosslinked, then the polystyrene network was polymerised and crosslinked using gamma irradiation to avoid possible thermal degradation of the butadiene segment of the SBS. Tough transparent systems were produced with no apparent thermal degradation of the polybutadiene segments. The epichlorohydrin/nitrile rubber IPNs were formed by simultaneous thermal crosslinking reactions. The epichlorohydrin network was formed using lead based crosslinker, while the nitrile rubber was crosslinked by peroxide methods. The use of two different crosslinking systems was employed in order to achieve independent crosslinking thus resulting in an IPN with minimal grafting between the component networks. SANS, Transmission electron microscopy (TEM), and atomic force microscopy (AFM) were used to examine the size and shape of the phase domains and investigate any variation with crosslinking level and

    1. Introduction The nitrogen (N) dynamics in forest soils in the Japanese archipelago varies widely because it extends for 3000 km and the climatic zone ranges from cool-temperate to subtropical region. Therefore, it is necessary to understand the soil N transformation characteristics and its controlling factors across a wide area because the changes in N dynamics due to the climate change are expected to differ from region to region. In this study, we selected more than 30 sites from across the Japanese archipelago and measured net rates of soil N mineralization and nitrification. Also, we measured the physical, chemical and biological properties of soil to clarify the controlling factors. 2. Materials and methods We established an experimental plot (20 * 20 m) at each site, and at each plot, five soil sampling locations were established. At each sampling location, mineral soil samples were collected from 0-10, 10-30, 30-50 cm in depth. Net and gross N mineralization and nitrification rate, soil pH(H2O), water soluble cation (Ca2+, Mg2+, K+, Na+, NH4+, Al3+), anion (Cl-, NO3-, SO42-), and organic carbon (WSOC) were measured. From the net N mineralization and nitrification rate measured by laboratory incubation at three different temperatures (15, 20, 25 °C), Q10min, Q10nit (Q10 of N mineralization and nitrification) and average net rate at 20 °C (N20min and N20nit) were calculated. 3. Results and discussion In most of the sites, net N mineralization and nitrification rates were higher in the shallower soil layers. N20min and N20nit ranged 0.01-3.23 and 0.00-3.00 mgN/kg/d, respectively and Q10min and Q10nit ranged 1.09-24.16 and 1.38-20.10 respectively. There was a pattern that low rates soil (N20 Soils which had high N mineralization rates had also high nitrification rates. Soils with high N mineralization and nitrification rate were mostly located in the northern region (Hokkaido Island and Tohoku region) in Japan. This suggests that soil type distribution in

  14. Multibeam focusing in SANS technique

    Len, A.; Pepy, G.; Rosta, L

    2004-07-15

    The use of four beams separated by a cross-shaped aluminum plate inside the collimator tube, placed at the exit of the 40x40 mm{sup 2} guide of the Budapest Neutron Center's small-angle neutron scattering (SANS) spectrometer, allowed us to gain a factor close to 4 in neutron intensity. The aluminum separator and the inner surface of the collimator vacuum tube was coated with boron carbide. The cross-section of each beam was 8x8 mm{sup 2} at the sample position. This setting can be used for measuring large, homogeneous samples, when the measurement does not need high spatial resolution. The beams were focused on the detector by appropriate diaphragms, the collimation length and the sample-detector distance were 4700 mm. In a real SANS experiment we have compared measurements performed on tungsten wire samples with and without beam separator. Using this beam multiplicator the measurement time could be reduced to a quarter.

  15. MAPP in action in San Antonio, Texas.

    Shields, Kathleen M; Pruski, Charles E

    2005-01-01

    San Antonio was selected as an official Mobilizing for Action through Planning and Partnerships (MAPP) demonstration site by National Association of County and City Officials in 2000. The San Antonio Metropolitan Health District, under the leadership of Dr Fernando A. Guerra, agreed to facilitate the process. The MAPP process provided the San Antonio Metropolitan Health District, the local public health authority, a defined process for community health improvement, as well as a mechanism to help bridge the gap between public health and the community. The San Antonio Metropolitan Health District organized a Core Planning Team to lead the MAPP process in April 2001. By October 2002, the Core Planning Team was expanded to a full community working group named the Alliance for Community Health in San Antonio and Bexar County (Alliance). The Alliance identified six strategic issues, which eventually became the basis of the San Antonio Community Health Improvement Plan. The strategic issues are Public Policy, Data Tracking, Healthy Lifestyles, Promoting a Sense of Community, Access to Care, and Safe Environment. San Antonio's MAPP experience has been successful in bringing together the public health system partners, and establishing public health priorities collectively. The MAPP process has resulted in the development of many new initiatives, and, most important, has opened the door to many partnership opportunities in the future. The work of the Alliance, through the MAPP process, has helped to leverage resources for public health improvement in San Antonio, and has the potential to effect positive change in public health in the future.

  19. APPLICATION OF RESERVOIR CHARACTERIZATION AND ADVANCED TECHNOLOGY TO IMPROVE RECOVERY AND ECONOMICS IN A LOWER QUALITY SHALLOW SHELF SAN ANDRES RESERVOIR

    The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: (1) Advanced petrophysics; (2) Three-dimensional (3-D) seismic; (3) Crosswell bore tomography; (4) Advanced reservoir simulation; (5) Carbon dioxide (CO2) stimulation treatments; (6) Hydraulic fracturing design and monitoring; and (7) Mobility control agents

    The OXY-operated Class 2 Project at West Welch is designed to demonstrate how the use of advanced technology can improve the economics of miscible CO{sub 2} injection projects in lower quality Shallow Shelf Carbonate reservoirs. The research and design phase (Budget Period 1) primarily involved advanced reservoir characterization. The current demonstration phase (Budget Period 2) is the implementation of the reservoir management plan for an optimum miscible CO{sub 2} flood design based on the reservoir characterization. Although Budget Period 1 for the Project officially ended 12/31/96, reservoir characterization and simulation work continued during the Budget Period 2. During the seventh annual reporting period (8/3/00-8/2/01) covered by this report, work continued on interpretation of the interwell seismic data to create porosity and permeability profiles which were distributed into the reservoir geostatistically. The initial interwell seismic CO{sub 2} monitor survey was conducted and the acquired data processed and interpretation started. Only limited well work and facility construction were conducted in the project area. The CO{sub 2} injection initiated in October 1997 was continued, although the operator had to modify the operating plan in response to low injection rates, well performance and changes in CO{sub 2} supply. CO{sub 2} injection was focused in a smaller area to increase the reservoir processing rate. By the end of the reporting period three producers had shown sustained oil rate increases and six wells had experienced gas (CO{sub 2}) breakthrough.

  3. Isla del Coco, on Cocos Plate, Converges with Isla de San Andrés, on the Caribbean Plate, at 78 mm/yr

    Protti, M.; Gonzalez, V. M.; Freymueller, J. T.; Doelger, S.

    2013-05-01

    Isla del Coco is the only land mass of the Cocos Plate that emerges above sea level. This makes it the only place where Cocos Plate motion can be measured using Global Navigation Satellite System (GNSS) monitoring. Global Positioning System (GPS) observations have been carried out sporadically over more than two decades on Isla del Coco, allowing precise measurement of the motion of the Cocos Plate. Recently, in May 2011, a continuous GPS station was built and instrumented at Isla del Coco, in Wafer Bay, by OVSICORI UNA and UNAVCO, as part of the COCONet regional GNSS network. Position time series from this CGPS station (ISCO: Isla del Coco) show a steady motion of Isla del Coco at a speed of 90.9±1.5mm/yr in the N35oE direction in ITRF2008 and convergence with the Caribbean Plate at 78±1mm/yr. This result is consistent with the findings of the earliest GPS studies, and agrees within uncertainty with the estimated convergence rate of 76.4±2.6 mm/yr of the MORVEL plate motion model. MORVEL is based on an average over the last 780,000 years, and our result suggests that Cocos Caribbean plate motions have been constant over that time interval.

  5. Informal governance through patron–client relationships and destructive fishing in Spermonde Archipelago, Indonesia

    Nurliah Nurdin

    2014-12-01

    Full Text Available Efforts to preserve fragile ecosystems that focus on removing human intervention from the environment risk ignoring the political and social systems underlying environmentally destructive economic activities. In contrast, a biocultural diversity perspective allows for environmental protection to be approached with sensitivity to human needs. This paper explores the case of Karanrang Island, Spermonde Archipelago, South Sulawesi, Indonesia, where fishing with toxins and bombs is proving detrimental to fish stocks and the surrounding coral reefs. Interviews with Karanrang fishers reveal that these destructive fishing practices are bound up with the region’s punggawa-sawi political and social system of patron–client relationships. The paper shows how the informal governance operating through these patron–client relationships traps fishers into destructive fishing practices. It is argued that environmental protection efforts should take into account political and social contexts.

    2002-01-01

    In order to study the matrilineal genetic composition in Cabo Verde (Republic of Cape Verde), an archipelago that used to serve as a Portuguese entrepôt of the Atlantic slave trade, we have analysed a total of 292 mtDNAs sampled from the seven inhabited islands for the hypervariable segment I (HVS-I) and some characteristic RFLPs of the coding regions. The different settlement history of the northwestern group of the islands is well reflected in the mtDNA pool. The total Cabo Verde sample clearly displays the characteristic mitochondrial features of the Atlantic fringe of western Africa and testifies to almost no mitochondrial input from the Portuguese colonizers.

  7. Recent International and Domestic Migration in the Maltese Archipelago: An Economic Review

    Rose Marie Azzopardi

    2012-05-01

    Full Text Available Migration strategies often permit densely populated island territories to alleviate unemployment, ease pressure on limited resources, and compensate for the absence of economic diversification. This paper evaluates two types of recent migratory flows affecting the Maltese archipelago: international migration to and from the islands triggered or intensified by European Union membership; and domestic, inter-island movements between the ‘mainland’ (Malta and the smaller island (Gozo.The descriptive statistics used are based on published data, whilst the qualitative evaluation is derived from focus groups and interviews with stakeholders. Conclusions suggest that emigration remains an overall positive experience at the individual level, with constructive spill-over effects, mingling of cultures and better use of resources at the national level. Such benefits can be expected to increase if authorities design policies which encourage rather than discourage migratory flows.

  8. Local Culture as a Resource in Regional Development in the Southwest-Finland Archipelago

    Katriina Siivonen

    2009-12-01

    Full Text Available In cultural and regional politics in the European Union, and in practice for instance in the Southwest-Finland Archipelago, local culture and cultural heritage are considered resources. Global boundlessness, heterogeneity and change are basic qualities of culture. However, in regional development, culture is seen and used as a number of different local cultures with their own essential cultural heritage. The culture of local everyday life is opposite to, and in tension with, the construct of cultures used in regional development. Accordingly, culture should primarily be safeguarded as a heterogenic, dynamic and interactive process of everyday life. This process is the most important resource of local culture. In addition, culture should be safeguarded as value-based cultural constructions, such as brands or common identities of certain cultures, with for instance cultural heritage as a part of it. In the latter case, a common, transparent definition of these brands, identities and cultural heritages with their different values, is needed.

    This study presents the chemical composition of VOCs in air and gas discharges collected at Nisyros Island (Dodecanese Archipelago, Greece). The main goals are i) to discriminate between natural and anthropogenic VOC sources and ii) to evaluate their impact on local air quality. Up to 63 different VOCs were recognized and quantitatively determined in 6 fumaroles and 19 air samples collected in the Lakki caldera, where fumarolic emissions are located, and the outer ring of the island, including the Mandraki village and the main harbor. Air samples from the crater area show significant concentrations of alkanes, alkenes, cyclic, aromatics, and S- and O-bearing heterocycles directly deriving from the hydrothermal system, as well as secondary O-bearing compounds from oxidation of primary VOCs. At Mandraki village, C6H6/Σ(methylated aromatics) and Σ(linear)/Σ(branched) alkanes ratios pipes of touristic and private boats and buses. PMID:23747819

This holds both for total species number, for native species number, for endemic species number and for total number of seed plants as well as number of endemic seed plants......By simple and multiple regression analyses we investigate updated species numbers of endemic and native vascular plants and seed plants in the Galapagos Archipelago in relation to geographical parameters. We find that the best models to describe species numbers are regression models with log-transformed....... For the ratio between endemic and native species, modified area is also the major significant variable, but with a negative regression slope. Multiple regression models show that some isolation measures are significant contributors and may explain some of the residual variation, but their contribution...

  11. Properties of diphenolase from Vanilla planifolia (Andr.) shoot primordia cultured in vitro.

    Debowska, R; Podstolski, A

    2001-07-01

    Properties of diphenolase (PPO, EC1.10.3.1) from vanilla (Vanilla planifolia Andr.) shoot primordia culture were investigated. Two pH optima of the enzyme extraction at pH 6 and 8 were found. Nevertheless, the enzymes shared the same optimum pH of activity-between pH 3 and 4. Sodium dodecyl sulfate slightly improved diphenolase extraction but caused a 3-fold increase in its specific activity. The extracts of pH 6 and 8.0 revealed three isozyme bands after polyacrylamide gel electrophoresis-two of them were similar in both extracts and two distinct. The enzyme showed high thermal stability-no loss was observed after 120 min at 50 degrees C. Diethyldithiocarbamic acid, ethylenediaminetetracetic acid disodium salt, ethylene glycol bis(beta-aminoethyl ether) N,N,N',N'-tetraacetic acid, L-ascorbic acid, dithiothreitol, glutathione (reduced), and beta-mercaptoethanol were found to be potent inhibitors of the diphenolase studied. The enzyme showed also monophenolase activity. Km and Vmax were calculated with monophenols [p-coumaric acid, 3-(p-hydroxyphenyl)propionic acid, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, 4-hydroxybenzoic acid] and with diphenols (caffeic acid, hydrocaffeic acid, chlorogenic acid, 4-methylcatechol, protocatechuic aldehyde and acid, and 3,4-dihydroxyphenylalanine). The highest Vmax was found with 4-hydroxybenzyl alcohol and the greatest affinity to protocatechuic acid, respectively-the most abundant monophenol and one of the least abundant o-diphenols in the studied Vanilla tissue.

    1993-01-01

    This work is based on my thesis from Aix en Provence on French Civilisation and Letters (1984). The head of the examinations was the writer Raymond Jean. My idea is to show how the decadent writer and poet Marc André Raffalovich fought against the personalities in science concerning homosexuality with a new point of view and with great difficulty, shedding new light on this subject in a review from 1886 to 1914 under the direction of Dr. Alexandre Lacassagne Les Archives d'Anthropologie Criminelle de Médecine Légale et de Psychologie Normale et Pathologique published in 1886, edited by the director A. Lacassagne, professor and chairman of legal medicine, Lyon, and author of the article "Pederastie," Dictionnaire Encyclopedique des Sciences Medicales, volume XXII published in 1886. In 1893, he wrote an introduction for l'Inversion Sexuelle of Dr. Julien Chevalier (Paris: Masson-Lyon Storck). This monthly review "d'au moins 80 pages" was called L'Ecole Lyonnaise, and so to say, l'Ecole Francaise d'Anthropologie Criminelle, which defends against l'Ecole Italienne of Lombroso, the culturalist theory of the birth of the criminal; according to this école du milieu social: "La Société a les criminels qu'elle merite" (The society has criminals it deserves). After the first world war, it was to be overridden by the Marxist analysis. PMID:8301079

    Full Text Available Esse artigo tem por objetivo apresentar a trajetória profissional de André Midani, provavelmente o mais importante executivo da história da indústria fonográfica no Brasil. Nascido na Síria, Midani chegou ao Brasil nos anos 50, ingressando imediatamente na indústria. Sua trajetória, desenvolvida especialmente nas gravadoras Odeon (EMI, Phillips/Polygram (Universal Music e Warner, está profundamente ligadas a importantes movimentos da música popular brasileira como a Bossa Nova, o Tropicalismo, a Brazilian Black Music e o Rock Brasileiros dos anos 80. Além disso, o modelo de atuação empregado por Midani- baseado, segundo suas palavras, na promoção do artista e não da música- pode oferecer um interessante contraponto para a discussão do cenário atual e da crise que parece atingir globalmente a indústria do disco.

  14. La conquista interior de la vida. Le Corbusier y André Malraux

    Ana Sofía Pereira da Silva

    2016-05-01

    Escritos de ambos autores y algunas obras de Le Corbusier –Museo Mundial del Mundaneum y Museo de Crecimiento Ilimitado– serán observados con el sentido de mapear las afinidades existentes entre los dos autores. Sin embargo, las circunstancias pragmáticas de la vida a  menudo se entrometen oponiendo lo que suele estar en consonancia. La clasificación de monumento histórico atribuida por André Malraux a la Villa Savoye, mientras fuera Ministro de los Asuntos Culturales, es presentada con la intuición de salvar una de las obras maestras de Le Corbusier. Sin embargo, esta acción terminó impidiendo al arquitecto encontrar en la degradación de la Villa Savoye un pretexto para su transformación, en una primera fase, vetándole también, finalmente, el proyecto de la  restauración de la casa, que es confiada a un arquitecto de los Monumentos Nacionales.2 Este momento intuido de fricción entre los dos  autores será motivo de observación, no arriesgando la evidente afinidad entre los dos.

  15. An invasive fish and the time-lagged spread of its parasite across the Hawaiian archipelago.

    Michelle R Gaither

    Full Text Available Efforts to limit the impact of invasive species are frustrated by the cryptogenic status of a large proportion of those species. Half a century ago, the state of Hawai'i introduced the Bluestripe Snapper, Lutjanus kasmira, to O'ahu for fisheries enhancement. Today, this species shares an intestinal nematode parasite, Spirocamallanus istiblenni, with native Hawaiian fishes, raising the possibility that the introduced fish carried a parasite that has since spread to naïve local hosts. Here, we employ a multidisciplinary approach, combining molecular, historical, and ecological data to confirm the alien status of S. istiblenni in Hawai'i. Using molecular sequence data we show that S. istiblenni from Hawai'i are genetically affiliated with source populations in French Polynesia, and not parasites at a geographically intermediate location in the Line Islands. S. istiblenni from Hawai'i are a genetic subset of the more diverse source populations, indicating a bottleneck at introduction. Ecological surveys indicate that the parasite has found suitable intermediate hosts in Hawai'i, which are required for the completion of its life cycle, and that the parasite is twice as prevalent in Hawaiian Bluestripe Snappers as in source populations. While the introduced snapper has spread across the entire 2600 km archipelago to Kure Atoll, the introduced parasite has spread only half that distance. However, the parasite faces no apparent impediments to invading the entire archipelago, with unknown implications for naïve indigenous Hawaiian fishes and the protected Papahānaumokuākea Marine National Monument.

  16. Genetic tests for ecological and allopatric speciation in anoles on an island archipelago.

    Roger S Thorpe

    2010-04-01

    Full Text Available From Darwin's study of the Galapagos and Wallace's study of Indonesia, islands have played an important role in evolutionary investigations, and radiations within archipelagos are readily interpreted as supporting the conventional view of allopatric speciation. Even during the ongoing paradigm shift towards other modes of speciation, island radiations, such as the Lesser Antillean anoles, are thought to exemplify this process. Geological and molecular phylogenetic evidence show that, in this archipelago, Martinique anoles provide several examples of secondary contact of island species. Four precursor island species, with up to 8 mybp divergence, met when their islands coalesced to form the current island of Martinique. Moreover, adjacent anole populations also show marked adaptation to distinct habitat zonation, allowing both allopatric and ecological speciation to be tested in this system. We take advantage of this opportunity of replicated island coalescence and independent ecological adaptation to carry out an extensive population genetic study of hypervariable neutral nuclear markers to show that even after these very substantial periods of spatial isolation these putative allospecies show less reproductive isolation than conspecific populations in adjacent habitats in all three cases of subsequent island coalescence. The degree of genetic interchange shows that while there is always a significant genetic signature of past allopatry, and this may be quite strong if the selection regime allows, there is no case of complete allopatric speciation, in spite of the strong primae facie case for it. Importantly there is greater genetic isolation across the xeric/rainforest ecotone than is associated with any secondary contact. This rejects the development of reproductive isolation in allopatric divergence, but supports the potential for ecological speciation, even though full speciation has not been achieved in this case. It also explains the

  17. Sea ice melt onset dynamics in the northern Canadian Arctic Archipelago from RADARSAT

    Mahmud, M. S.; Howell, S.; Geldsetzer, T.; Yackel, J.

    2015-12-01

    Sea ice melt onset, the appearance of liquid water in its snow cover, decreases surface albedo which increases shortwave absorption and thereby accelerates snow and sea ice melting. Earlier melt onset leads to the earlier formation of open water which enhances the ice-albedo feedback. Sea ice melt onset timing and duration vary considerably, both spatially and temporally, owing to variability in atmospheric forcing; this in turn influences the September sea ice extent. Sea ice melt onset variability has been investigated using coarse resolution passive microwave observation in Canadian Arctic Archipelago (CAA); however, this does not provide sufficient information about sea ice melt dynamics. We developed a new melt onset algorithm using high resolution synthetic aperture radar (SAR) images from RADARSAT to better understand sea ice melt onset dynamics in northern Canadian Arctic Archipelago (fig 1) from 1997 to 2014. The algorithm is based on the temporal evolution of the SAR backscatter coefficient (σo), using separate thresholds for seasonal first-year ice and multi-year ice. Results indicated that the mean annual average melt onset date in the northern CAA was on year day 164 (mid-June) with a standard deviation of 4 days over the 18 year period. No significant trend for melt onset date was found over the 18 year period (fig: 2) but extreme early melt onset was detected in 1998 and 2012 associated with anomalous atmospheric forcing. Spatially, sea ice onset over the entire northern CAA varied from a 10-day minimum in 2007, to a 35-day maximum in 2011 and exhibited negative correlation (r=0.70) with the rate of increase in surface air temperature (fig 3) derived from Extended AVHRR Polar Pathfinder (APP-x) dataset. An earlier (later) melt onset also results in light (heavier) September sea ice area in the northern CAA (fig 4).

  18. Comparison of Two Independent Mapping Exercises in the Primeiras and Segundas Archipelago, Mozambique

    2016-01-01

    Full Text Available Production of coral reef habitat maps from high spatial resolution multispectral imagery is common practice and benefits from standardized accuracy assessment methods and many informative studies on the merits of different processing algorithms. However, few studies consider the full production workflow, including factors such as operator influence, visual interpretation and a-priori knowledge. An end-user might justifiably ask: Given the same imagery and field data, how consistent would two independent production efforts be? This paper is a post-study analysis of a project in which two teams of researchers independently produced maps of six coral reef systems of the archipelago of the Primeiras and Segundas Environmental Protected Area (PSEPA, Mozambique. Both teams used the same imagery and field data, but applied different approaches—pixel based vs. object based image analysis—and used independently developed classification schemes. The results offer a unique perspective on the map production process. Both efforts resulted in similar merged classes accuracies, averaging at 63% and 64%, but the maps were distinct in terms of scale of spatial patterns, classification disparities, and in other aspects where the mapping process is reliant on visual interpretation. Despite the difficulty in aligning the classification schemes clear patterns of correspondence and discrepancy were identified. The maps were consistent with respect to geomorphological level mapping (17 out of 30 paired comparisons at more than 75% agreement, and also agreed in the extent of coral containing areas within a difference of 16% across the archipelago. However, more detailed benthic habitat level classes were inconsistent. Mapping of deep benthic cover was the most subjective result and dependent on operator visual interpretation, yet this was one of the results of highest interest for the PSEPA management since it revealed a continuity of benthos between the islands

    Green Jacks, Caranx caballus, are distributed along the Eastern Pacific coast. In Panama, C. caballus was heavily fished around Las Perlas Archipelago to sustain local markets until 2007, when the archipelago was declared a marine protected area. This first study in Panama, analyzed a sample of 4 990 individuals from Las Perlas, obtained monthly from June 2005 to June 2006, from landings at the central fish market. Average total length was 36.1 +/- 6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within +/-10% of the optimal length but only six (15%) were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE) was best predicted by minimum annual values of the Multivariate ENSO/LNSO Index (MEI) (R2=0.54). Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of mega-spawners in the population and guarantee the sustainability of this resource.

  1. Late Paleozoic accretionary complexes on the Gondwana margin of southern Chile: Evidence from the Chonos Archipelago

    Davidson, John; Mpodozis, Constantino; Godoy, Estanislao; Hervé, Francisco; Pankhurst, Robert; Brook, Maureen

    The late Paleozoic "basement" rocks that crop out along the Pacific side of the Chonos Archipelago (44°-46°S) can be divided into two north-south trending belts: (1) an eastern belt formed of submarine fan-turbidites and subordinate pelagic cherts, each containing well-preserved primary sedimentary structures, and (2) a western belt, mainly formed by strongly foliated mica schists and greenschists. Trace element contents in the cherts and greenschists indicate rocks of oceanic affinity. The structures present within the eastern rock suite are principally subiso-clinal folds (with tectonic imbrication) and locally developed zones of broken formation. The transition from these rocks into the foliated schists appears to be related to a progressive increase in metamorphism and strain associated with the development of westward verging recumbent folds and a flat-lying crenulation cleavage. It is inferred that these structures developed during the construction of a Late Carboniferous-Early Permian accretionary prism (about 260 Ma Rb-Sr ages), although sedimentation may have taken place throughout the upper Paleozoic. Rb-Sr whole-rock isochrons giving Late Jurassic to Early Cretaceous ages for some localities may indicate much later development of S2 structures. Alternatively, they may represent isotopic resetting by hydrothermal effects during the emplacement of transgressive Early Cretaceous granites, one of which gives a new Rb-Sr isochron age of 125±2Ma. This overall scenario seems to be consistent with that reported in the slightly older coastal metamorphic basement north of 34°S and equivalent or younger complexes farther south in the Madre de Dios Archipelago.

  2. Benthic Habitat Mapping and Biodiversity Analysis in the Primeiras and Segundas Archipelago Reserve

    Teixeira, L.; Nilsson, M.; Hedley, J.; Shapiro, A.

    2015-04-01

    The Primeiras and Segundas Archipelago Reserve is a recently established marine protected area, the largest in Africa, located in the waters of Northern Mozambique. This protected area is of significant local economic importance and global ecological relevance, containing the southernmost coral reefs in Eastern Africa. However, information related to the marine ecosystem, notably benthic habitat is very scarce. Twelve atolls were mapped in the region using object-based image classification of very-high resolution satellite imagery (IKONOS, Quickbird, and WorldView-2). Geographically referenced data on benthic cover and depth were gathered in the course of three fieldwork expeditions covering a total of four atolls and two shallow reef structures in the Segundas Archipelago. The resulting map allows the estimation of three distinct types of coral cover (field, patches, spurs and grooves); the differentiation of sand, rubble and rock substrate; and the detection of seagrass and brown macroalgae, identifying up to 24 benthic habitats. Average overall accuracy was above 50%. The high variability of the optical properties on the reef systems, in large due to the connectivity with the mainland via plumes, while interesting from an ecological perspective increases the challenges for remote sensing of bottom cover. New information indicates the presence of deep benthic cover extending from the atolls, suggesting the need for further research on Coastal Eastern African corals, namely on their resilience and connectivity, and supporting current knowledge of the existence of an almost continuous coral reef from Kenya to Mozambique. Coral and fish biodiversity data have been analysed together with the satellite-derived maps. Results support the local perception that ecosystems are in decline and uncover new information about biodiversity's spatial patterns. Our work provides a detailed depiction of marine habitats that may aid the management of the protected area, namely in

  3. The terrestrial reptile fauna of the Abrolhos Archipelago: species list and ecological aspects.

    Rocha, C F D; Dutra, G F; Vrcibradic, D; Menezes, V A

    2002-05-01

    We have studied the terrestrial reptile fauna of the Abrolhos Archipelago (a group of five islands located ca. 70 km off the southern coast of the State of Bahia, Brazil) and analyze here some of its ecological aspects such as diet, thermal ecology, activity, and some reproductive parameters. Three lizards comprise the archipelago's terrestrial reptile fauna: Tropidurus torquatus (Tropiduridae), Mabuya agilis (Scincidae), and Hemidactylus mabouia (Gekkonidae). The first two are diurnal and the latter is crepuscular/nocturnal (initiating activity at ca. 17:30). The activity period of T. torquatus extended from 5:30 to 18:30 h. Mean field body temperatures of active T. torquatus, M. agilis, and H. mabouia were, respectively, 34.0 +/- 3.7 degrees C (range 23.8-38.0 degrees C; N = 75), 34.5 +/- 2.2 degrees C (range 30.8-37.0 degrees C; N = 6), and 26.3 +/- 1.1 degrees C (range 24.8-28.0 degrees C; N = 8). The predominant prey items in the diet of T. torquatus were ants, coleopterans, and hemipterans. In the diet of M. agilis, coleopterans were the most frequent prey items. For H. mabouia, the most important dietary items were orthopterans. Clutch size of T. torquatus averaged 4.1 +/- 1.1 (range 2-6; N = 15) and was significantly related to female size (R2 = 0.618; p = 0.001; N = 15). Clutch size for H. mabouia was fixed (two) and mean litter size of the viviparous M. agilis was 3.3 +/- 0.6 (range 3-4; N = 3). Tropidurus torquatus and H. mabouia deposit their eggs under rocks in the study area, with the former burying them but not the latter; in both species, more than one female often oviposit under the same rock.

    Madeira forms a mid-Atlantic volcanic archipelago, whose economy is largely dependent on tourism. There, one can encounter different types of sand beach: natural basaltic, natural calcareous and artificial calcareous. Microbiological and mycological quality of the sand was analyzed in two different years. Bacterial indicators were detected in higher number in 2010 (36.7% of the samples) than in 2011 (9.1%). Mycological indicators were detected in a similar percentage of samples in 2010 (68.3%) and 2011 (75%), even though the total number of colonies detected in 2010 was much higher (827 in 41 samples) than in 2011 (427 in 66 samples). Enterococci and potentially pathogenic and allergenic fungi (particularly Penicillium sp.) were the most common indicators detected in both years. Candida sp. yeast was also commonly detected in the samples. The analysis of the 3rd quartile and maximum numbers of all indicators in samples showed that artificial beaches tend to be more contaminated than the natural ones. However, a significant difference between the variables was lacking. More monitoring data (number of bathers, sea birds, radiation intensity variation, and a greater number of samples) should be collected in order to confirm if these differences are significant. In general, the sand quality in the archipelago's beaches was good. As the sand may be a vector of diseases, an international common set of indicators and values and a compatible methodologies for assessing sand contamination, should be defined, in order to provide the bather's with an indication of beach sand quality, rather than only the water.

    1985-08-01

    Small-angle neutron scattering (SANS) has proved to be an excellent technique for the study of complex fluids. This article introduces SANS from the viewpoint of such studies. The use of SANS to determine the structures of concentrated micellar fluids is then discussed within the framework of current one-component macrofluid (OCM) models, and experimental examples are taken from several contemporary studies. Finally, the discussion is extended to magnetic fluids (ferrofluids) in which the neutron magnetic interaction plays an important experimental role. 25 refs., 11 figs., 1 tab.

    1982-01-01

    The creation and use of a vertically integrated data base, including LANDSAT data, for local planning purposes in a portion of San Bernardino County, California are described. The project illustrates that a vertically integrated approach can benefit local users, can be used to identify and rectify discrepancies in various data sources, and that the LANDSAT component can be effectively used to identify change, perform initial capability/suitability modeling, update existing data, and refine existing data in a geographic information system. Local analyses were developed which produced data of value to planners in the San Bernardino County Planning Department and the San Bernardino National Forest staff.

    2006-06-01

    Full Text Available Out of the Spanish novels published between 1980 and 2000, there is quite an extensive collection that deal with specific aspects of the consequences about the postmodern episteme in Spanish narrative in a more or less partial way: the deconstruction of ego and reality, the end of lineal time and history, the intertextual irony and parody, the end of utopia, the pastiche as structural tool... Nevertheless, the complete demonstration of all that can be theoretically described as Spanish postmodern novel can be found in Andrés Ibáñez’s texts: La música del mundo o El efecto Montoliu (1995 and El mundo en la era de Varick (1999. In these novels, Andrés Ibáñez proposes a new way of perceiving reality that takes on and surpasses the logical-rational outlines of Modernism: the look of Postmodernism.Existe un corpus bastante amplio de novelas españolas publicadas entre 1980 y 2000 que, de forma más o menos parcial, cubren aspectos concretos de las consecuencias de la episteme posmoderna en la narrativa española: la deconstrucción del sujeto y la realidad, el fin del tiempo y de la historia lineal, la ironía y la parodia intertextual, el fin de la utopía, el pastiche como herramienta estructural...

    André Brink’s novel A Dry White Season (1979) is strictly connected with the time and place in which it was written. Its dialogue with the real Johannesburg of the late Seventies is manifest: characters and plot are grafted on real events, like the youth riots in Soweto (1976) and the death of Steve Biko in the hands of the Security Police (1977). Brink’s early novels have been commended for their political commitment, but also criticized for being ‘easily’ documentary. Yet, A Dry White Seaso...

Nevertheless, his analysis of the content of the Qur’ān differs f...

  16. Defining Boundaries for Ecosystem-Based Management: A Multispecies Case Study of Marine Connectivity across the Hawaiian Archipelago

    Robert J. Toonen

    2011-01-01

    Full Text Available Determining the geographic scale at which to apply ecosystem-based management (EBM has proven to be an obstacle for many marine conservation programs. Generalizations based on geographic proximity, taxonomy, or life history characteristics provide little predictive power in determining overall patterns of connectivity, and therefore offer little in terms of delineating boundaries for marine spatial management areas. Here, we provide a case study of 27 taxonomically and ecologically diverse species (including reef fishes, marine mammals, gastropods, echinoderms, cnidarians, crustaceans, and an elasmobranch that reveal four concordant barriers to dispersal within the Hawaiian Archipelago which are not detected in single-species exemplar studies. We contend that this multispecies approach to determine concordant patterns of connectivity is an objective and logical way in which to define the minimum number of management units and that EBM in the Hawaiian Archipelago requires at least five spatially managed regions.

  17. Ice mass loss in Greenland, the Gulf of Alaska, and the Canadian Archipelago: Seasonal cycles and decadal trends

    Harig, Christopher; Simons, Frederik J.

    2016-04-01

    Over the past several decades mountain glaciers and ice caps have been significant contributors to sea level rise. Here we estimate the ice mass changes in the Canadian Archipelago, the Gulf of Alaska, and Greenland since 2003 by analyzing time-varying gravimetry data from the Gravity Recovery and Climate Experiment. Prior to 2013, interannual ice mass variability in the Gulf of Alaska and in regions around Greenland remains within the average estimated over the whole data span. Beginning in summer 2013, ice mass in regions around Greenland departs positively from its long-term trend. Over Greenland this anomaly reached almost 500 Gt through the end of 2014. Overall, long-term ice mass loss from Greenland and the Canadian Archipelago continues to accelerate, while losses around the Gulf of Alaska region continue but remain steady with no significant acceleration.

  18. Competing Notions of Diversity in Archipelago Tourism: Transport Logistics, Official Rhetoric and Inter-Island Rivalry in the Azores

    Eduardo Costa Duarte Ferreira

    2013-05-01

    Full Text Available Contending and competing geographies are often implicitly involved in archipelagic spaces. Various small island states and territories with multi-island geographies have flourishing tourism industries that presuppose an archipelagic experience: visitors are encouraged to explore and sample different island constituents of the territory. This strategy taps into different tourism niche markets, improves local value added, and shares tourism revenue beyond key nodes and urban centers. The organization of such an important economic activity however often reflects a ‘one-size-fits-all’, tightly coordinated, frequently contrived process that does not necessarily speak to the cultural and biogeographical forms of diversity that reside in the archipelago. This paper offers the notion of archipelago as a new way of rethinking problems and challenges encountered in island tourism, and then assesses the implications of this conceptualization on the representation of ‘the archipelago’ in the Azores, Portugal, and reviews what this approach means and implies for sustainable tourism policy.

  19. Feeding Habits of Introduced Black Rats, Rattus rattus, in Nesting Colonies of Galapagos Petrel on San Cristóbal Island, Galapagos.

    Riofrío-Lazo, Marjorie; Páez-Rosas, Diego

    2015-01-01

    Introduced rodents are responsible for ecosystem changes in islands around the world. In the Galapagos archipelago, their effects on the native flora and fauna are adverse, including the extinction of endemic rodents in some islands and the reduction in the reproductive success of the Galapagos petrel (Pterodroma phaeopygia) in its nesting zones. Understanding the feeding behavior of introduced rodents and their trophic interactions with native and non-native species on islands, can assist in the design of management strategies and conservation plans of invasive and endemic species respectively. Four petrel nesting colonies were monitored during June 2013 on San Cristóbal Island (El Plátano, El Junco, San Joaquín, and La Comuna). The feeding habits of black rats were evaluated by analyzing stomach contents and stable isotopes in hair. Three species of introduced rodents were captured. R. rattus was the most abundant at all sites (n=43, capture success (CS) = 55.8%), followed by the house mouse, Mus musculus (n = 17, CS = 37.8%), and the Norwegian rat, R. norvegicus (n = 4, CS = 4.5%), captured only at La Comuna. The omnivorous black rat ate mostly plants (98%) and arthropods (2%). Intact seeds of Miconia robinsoniana were the main food at all sites (relative abundance=72.1%, present in 95% of the analyzed stomachs), showing the black rats' possible role in the archipelago as endemic seed dispersers. There was no evidence of petrel's intake; however, its possible consumption is not discarded at all. The δ15N and δ13C analysis corroborated the primarily herbivorous diet of black rats. The isotopic signatures of the three rodent species reflect the inter- and intra-specific differential use of food resources. Black rat showed a wider diet in La Comuna, which was related to a lower availability of its primary prey and its ability to adapt to the available resources in its habitat. PMID:25984724

R. rattus was the most abundant at all sites (n=43, capture success (CS) = 55.8%), followed by the house mouse, Mus musculus (n = 17, CS = 37.8%), and the Norwegian rat, R. norvegicus (n = 4, CS = 4.5%), captured only at La Comuna. The omnivorous black rat ate mostly plants (98%) and arthropods (2%). Intact seeds of Miconia robinsoniana were the main food at all sites (relative abundance=72.1%, present in 95% of the analyzed stomachs), showing the black rats’ possible role in the archipelago as endemic seed dispersers. There was no evidence of petrel’s intake; however, its possible consumption is not discarded at all. The δ15N and δ13C analysis corroborated the primarily herbivorous diet of black rats. The isotopic signatures of the three rodent species reflect the inter- and intra-specific differential use of food resources. Black rat showed a wider diet in La Comuna, which was related to a lower availability of its primary prey and its ability to adapt to the available resources in its habitat. PMID:25984724

  2. Seismicity Pattern Changes before the M = 4.8 Aeolian Archipelago (Italy) Earthquake of August 16, 2010

    Salvatore Gambino; Antonino Laudani; Salvatore Mangiagli

    2014-01-01

    We investigated the seismicity patterns associated with an M = 4.8 earthquake recorded in the Aeolian Archipelago on 16, August, 2010, by means of the region-time-length (RTL) algorithm. This earthquake triggered landslides at Lipari; a rock fall on the flanks of the Vulcano, Lipari, and Salina islands, and some damages to the village of Lipari. The RTL algorithm is widely used for investigating precursory seismicity changes before large and moderate earthquakes. We examined both the spatial ...

    2016-01-01

    To study the water quality influenced by the anthropogenic activities and its impact on the phytoplankton diversity in the surface waters of Miaodao Archipelago, the spatiotemporal variations in phytoplankton communities and the environmental properties of the surface waters surrounding the Five Southern Islands of Miaodao Archipelago were investigated, based on seasonal field survey conducted from November 2012 to August 2013. During the survey, a total of 109 phytoplankton species from 3 groups were identified in the southern waters of Miaodao Archipelago, of which 77 were diatoms, 29 were dinoflagellates, and 3 were chrysophytes. Species number was higher in winter (73), moderate in autumn (70), but lower in summer (31) and spring (27). The species richness index in autumn (5.92) and winter (4.28) was higher than that in summer (2.83) and spring (1.41). The Shannon-Wiener diversity index was high in autumn (2.82), followed by winter (1.99) and summer (1.92), and low in spring (0.07). The species evenness index in autumn (0.46) and summer (0.39) was higher than that in winter (0.32) and spring (0.02). On the basis of principal component analysis (PCA) and redundancy analysis (RDA), we found that dissolved inorganic nitrogen (DIN) and chemical oxygen demand (COD) in spring, COD in summer, pH in autumn, and salinity and oil pollutant in winter, respectively, showed the strongest association with the distribution of phytoplankton diversity. The spatial heterogeneity of the southern waters of Miaodao Archipelago was quite obvious, and three zones, i.e., northeastern, southwestern and inter-island water area, were identified by cluster analysis (CA) based on key environmental variables.

  5. Archipelago-wide island restoration in the Galapagos Islands: reducing costs of invasive mammal eradication programs and reinvasion risk.

    Victor Carrion

    Full Text Available Invasive alien mammals are the major driver of biodiversity loss and ecosystem degradation on islands. Over the past three decades, invasive mammal eradication from islands has become one of society's most powerful tools for preventing extinction of insular endemics and restoring insular ecosystems. As practitioners tackle larger islands for restoration, three factors will heavily influence success and outcomes: the degree of local support, the ability to mitigate for non-target impacts, and the ability to eradicate non-native species more cost-effectively. Investments in removing invasive species, however, must be weighed against the risk of reintroduction. One way to reduce reintroduction risks is to eradicate the target invasive species from an entire archipelago, and thus eliminate readily available sources. We illustrate the costs and benefits of this approach with the efforts to remove invasive goats from the Galápagos Islands. Project Isabela, the world's largest island restoration effort to date, removed >140,000 goats from >500,000 ha for a cost of US$10.5 million. Leveraging the capacity built during Project Isabela, and given that goat reintroductions have been common over the past decade, we implemented an archipelago-wide goat eradication strategy. Feral goats remain on three islands in the archipelago, and removal efforts are underway. Efforts on the Galápagos Islands demonstrate that for some species, island size is no longer the limiting factor with respect to eradication. Rather, bureaucratic processes, financing, political will, and stakeholder approval appear to be the new challenges. Eradication efforts have delivered a suite of biodiversity benefits that are in the process of revealing themselves. The costs of rectifying intentional reintroductions are high in terms of financial and human resources. Reducing the archipelago-wide goat density to low levels is a technical approach to reducing reintroduction risk in the short

    Ciguatera fish poisoning (CFP), a disease caused by consuming fish that have accumulated ciguatoxins (CTXs) in their tissue, is regarded as the most prevalent form of intoxication in French Polynesia. Recently, the Australes, one of the least affected archipelago until the early 1980s, has shown a dramatic increase in its incidence rates in 2009 with unusual CFP cases. In the present work, potential health hazards associated with the proliferation of various marine phytoplankton species and t...

    Ikram, Abarrul; Insani, Andon [National Nuclear Energy Agency, P and D Centre for Materials Science and Technology, Serpong (Indonesia)

    2003-03-01

    SANS data from some standard samples have been obtained using BATAN-SANS instrument in Serpong. The experiments were performed for various experimental set-ups that involve different detector positions and collimator lengths. This paper describes the BATAN-SANS instrument briefly as well as the data taken from those experiments and followed with discussion of the results concerning the performance and calibration of the instrument. The standard samples utilized in these experiments include porous silica, polystyrene-poly isoprene, silver behenate, poly ball and polystyrene-poly (ethylene-alt-propylene). Even though the results show that BATAN-SANS instrument is in good shape, but rooms for improvements are still widely open especially for the velocity selector and its control system. (author)

  17. Exploring the new long-term (150 years) precipitation dataset in Azores archipelago

    Hernández, Armand; Trigo, Ricardo M.; Kutiel, Haim; Valente, Maria A.; Sigró, Javier

    2015-04-01

    Within the scope of the two major international projects of long-term reanalysis for the 20th century coordinated by NOAA (Compo et al. 2011) and ECMWF (Hersbach et al. 2013) the IDL Institute from the University of Lisbon has digitized a large number of long-term stations records from Portugal and former Portuguese Colonies (Stickler et al. 2014). Recently we have finished the digitization of all precipitation values from Ponta Delgada (capital of the Azores archipelago) obtaining an uninterrupted precipitation monthly time series since 1864 and additionally an almost complete corresponding daily precipitation series, with the exception of some years (1864/1872; 1878/1879; 1888/1905; 1931; 1936 and 1938) for which only monthly values are available. Here, we present an annually, seasonally and daily resolution study of the rainfall regime in Ponta Delgada for the last 150 years and the North Atlantic Oscillation (NAO) influence over this precipitation regime. The distribution of precipitation presents an evident seasonal pattern, with a strong difference between the 'rainy season' (November/March) and the 'dry season' (June/August) with very little rainfall. April/May and September/October correspond to the transitional seasons. The mean annual rainfall in Ponta Delgada is approximately 910 mm and is accumulated (on average) in about 120 rainy days. The precipitation regime in Azores archipelago reveals large inter-annual and intra-annual variability and both have increased considerably in the last decades. The entire studied period (1865-2012) shows an increase in the rainfall conditions between a drier earlier period (1865-1938) and a wetter recent period (1939-2012). At daily resolution, we have used an approach based on different characteristics of rain spells (consecutive days with rainfall accumulation) that has been proved to be satisfactory for the analysis of the different parameters related to the rainfall regime (Kutiel and Trigo, 2014). This approach

    Before dawn, on February 9, 1971, a magnitude 6.4 earthquake occurred in the San Fernando Valley of California. On the following day, theSan Fernando Valley Child Guidance Clinic, through radio and newspapers, offered mental health crises services to children frightened by the earthquake. Response to this invitation was immediate and almost overwhelming. During the first 2 weeks, the Clinic's staff counseled hundreds of children who were experiencing various degrees of anxiety. 

  1. Spatial distribution and sources of polychlorinated biphenyls in surface sediments from the Zhoushan Archipelago and Xiangshan Harbor, East China Sea.

    Wang, Xiaoyan; Xu, Huanzhi; Zhou, Yongdong; Wu, Changwen; Kanchanopas-Barnette, Praparsiri

    2016-04-15

    This study investigated ambient concentrations and potential sources of polychlorinated biphenyls (PCBs) in surface sediments from the Zhoushan Archipelago and adjacent Xiangshan Harbor. The ∑18PCB (total 18 PCB) concentrations ranged between 1.48 and 7.94ng/g d.w., average at 4.20ng/g d.w., presenting a low adverse environmental risk. Penta-CB was the dominant congener, contributing 46.01%-86.44% of the total PCBs. Concentrations of PCBs were highest in the northeastern part of the Zhoushan Archipelago and Xiangshan Harbor. Principal component analysis (PCA) showed that PCBs have a mixed origin; atmospheric deposition and PCB dispersion from paint flakings being the main sources of PCB pollution. Aroclor 1245 and Clophen A50 were the potential PCB sources in all sampling sites. This paper provides the first intensive survey and statistical analyses of PCB distributions and sources in the Zhoushan Archipelago and adjacent Xiangshan Harbor. This study may provide a reference to environmental protection and monitoring of PCB pollution in the East China Sea. PMID:26892201

  2. Size distribution and genetic diversity of the offshore rockfish (Pontinus kuhlii) from three Atlantic archipelagos and seamounts

    Catarino, Diana; Stefanni, Sergio; Menezes, Gui M.

    2013-12-01

    The offshore rockfish (Pontinus kuhlii) is a widespread demersal fish in the temperate eastern Atlantic. This species inhabits hard bottoms at depths between 100 and 600m and it is an important resource for the Azorean commercial fishing fleet. During several research fishing surveys in the Azores, Madeira and Cape Verde archipelagos diverse biological data on this species were collected. The degree of geographical population differentiation across the three Atlantic archipelagos was examined using two mitochondrial markers, control region (CR) and cytochrome b (cyt b). A total of 44 specimens were sequenced for each marker revealing high haplotypic diversity (CR: Hd=0.9736; cyt b: Hd=0.8520) and low nucleotide diversity (CR: π=0.0171; cyt b: π=0.0059). The sample size from the different subareas was limited but sufficient to reveal that no genetic structure was evident (ΦST=-0.0465 to -0.0224), suggesting the existence of one panmictic population. Despite very different exploitation rates between archipelagos, the size structure of P. kuhlii was very similar and inter-annual variation was also low. Exploitation rates are probably too low to significantly affect the size structure, even in the Azores where the species is a secondary target of the commercial fishery. In the Azores region this species is more abundant on seamounts, however bigger fishes tend to occur on island slope than on seamounts.

  3. Features of shoreline displacement in the Holocene of Franz josef Land Archipelago

    Barliaev, A.; Anisimov, M.

    2014-12-01

    Changes in the global sea level after the LGM caused the significant alteration in relation of land and sea in Arctic. The rise of the sea level in Arctic was accompanied with present tectonic processes. Marine terraces are formed with the combination of eustatic sea level fluctuations and glacioisostatic uplift of the territory with the significant role of complicated tectonic block movements. There are nearly about 150 radiocarbon ages data for Franz-Josef Land archipelago now. The represented conclusions are a generalization of the published data and results of our field researches with series of new radiocarbon dates. We managed to collect valuable factual material during the Russian Arctic National Park expedition in 2012. The distinctions of post-glacial rise of different islands and peculiarities of Holocene deglaciation were identified with the help of marine terraces analysis. The altitude of the terraces with the same age on different islands exceeds 15 meters in some cases. However, analysis of the data suggests that the continuous series of raised beaches from 35 m a.s.l. formed during the last 10000 years. It is impossible to build up an univocal model of emergence isobases with the existing data. Alexandra Land Island was the special object of this investigation. The large beach ridge from Lunar Ice Cap to Kropotkina Ice Cap divides the island on two parts. The northern one is covered with marine sediments, whereas the southern - with glaciofluvial sediments with negligible areas of marine sediments. The difference between the terraces' ages of Alexandra Land on the Dezhneva Bay shore and the northern shore of island suggests that: 1) In the early Holocene the rate of the transgression exceeded the tectonic uplift of the territory; 2) Formation of the large central beach ridge occurred near 6700 years ago, the maximum marine limit in the Alexandra Land Island; 3) The rate of the tectonic rise of the territory exceeded the eustatic sea level rise in

  4. Genetic diversity of Japanese encephalitis virus isolates obtained from the Indonesian archipelago between 1974 and 1987.

    Schuh, Amy J; Guzman, Hilda; Tesh, Robert B; Barrett, Alan D T

    2013-07-01

    Five genotypes (GI-V) of Japanese encephalitis virus (JEV) have been identified, all of which have distinct geographical distributions and epidemiologies. It is thought that JEV originated in the Indonesia-Malaysia region from an ancestral virus. From that ancestral virus GV diverged, followed by GIV, GIII, GII, and GI. Genotype IV appears to be confined to the Indonesia-Malaysia region, as GIV has been isolated in Indonesia from mosquitoes only, while GV has been isolated on three occasions only from a human in Malaysia and mosquitoes in China and South Korea. In contrast, GI-III viruses have been isolated throughout Asia and Australasia from a variety of hosts. Prior to this study only 13 JEV isolates collected from the Indonesian archipelago had been studied genetically. Therefore the sequences of the envelope (E) gene of 24 additional Indonesian JEV isolates, collected throughout the archipelago between 1974 and 1987, were determined and a series of molecular adaptation analyses were performed. Phylogenetic analysis indicated that over a 14-year time span three genotypes of JEV circulated throughout Indonesia, and a statistically significant association between the year of virus collection and genotype was revealed: isolates collected between 1974 and 1980 belonged to GII, isolates collected between 1980 and 1981 belonged to GIV, and isolates collected in 1987 belonged to GIII. Interestingly, three of the GII Indonesian isolates grouped with an isolate that was collected during the JE outbreak that occurred in Australia in 1995, two of the GIII Indonesian isolates were closely related to a Japanese isolate collected 40 years previously, and two Javanese GIV isolates possessed six amino acid substitutions within the E protein when compared to a previously sequenced GIV isolate collected in Flores. Several amino acids within the E protein of the Indonesian isolates were found to be under directional evolution and/or co-evolution. Conceivably, the tropical climate

  5. Chronology of eclipse "San Miao"

    Liu, Ci-Yuan

    2001-06-01

    The ancient book "Mozi" (5th century BC) records: "In ancient times, the San Miao tribes were in disarray. The sun rose in the evening...King Yu vanquished them. "King Yu is a prehistoric person living in 23-19th century BC. The strange phenomena "sun rose in evening" was explained as a large solar eclipse at sunset by Pang. Therefore investigations on it may lead to an important progress of Chinese chronology. After an analysis on all similar records in Chinese history, we pay main attention to the relationship of eclipse computations with parameter "c", the long term of earth's rotation rate. We have computed all the solar eclipses in that period by the way similar to that used for investigating the "double dawn" eclipse. By change parameter "c" in reasonable range (28-36 sec/cy2), we have found 11 possible results listed in a table. One figure shows the eclipse maps and relative "double dawn/dusk" areas while another one illustrates how the parameter "c" affects the result. For an exact conclusion of King Yu's chronology, we need further progress from both side: history which may limit the King Yu's period and astronomy which may limit the possible range of parameter "c".

  10. The San Andreas Fault 'Supersite' (Invited)

    Hudnut, K. W.

    2013-12-01

    An expanded and permanent Supersite has been proposed to the Committee on Earth Observation Satellites (CEOS) for the San Andreas Fault system, based upon the successful initial Group on Earth Observations (GEO) Geohazard Supersite for the Los Angeles region from 2009-2013. As justification for the comprehensive San Andreas Supersite, consider the earthquake history of California, in particular the devastating M 7.8 San Francisco earthquake of 1906, which occurred along the San Andreas Fault, as did an earthquake of similar magnitude in 1857 in southern California. Los Angeles was only a small town then, but now the risk exposure has increased for both of California's megacities. Between the San Francisco and Los Angeles urban areas lies a section of the San Andreas Fault known to creep continually, so it has relatively less earthquake hazard. It used to be thought of as capable of stopping earthquakes entering it from either direction. Transitional behavior at either end of the creeping section is known to display a full range of seismic to aseismic slip events and accompanying seismicity and strain transient events. Because the occurrence of creep events is well documented by instrumental networks such as CISN and PBO, the San Andreas Supersite can be expected to be especially effective. A good baseline level of geodetic data regarding past events and strain accumulation and release exists. Many prior publications regarding the occurrence of geophysical phenomena along the San Andreas Fault system mean that in order to make novel contributions, state-of-the-art science will be required within this Supersite region. In more recent years, the 1989 Loma Prieta earthquake struck adjacent to the San Andreas Fault and caused the most damage along the western side of the San Francisco Bay Area. More recently, the concern has focused on the potential for future events along the Hayward Fault along the eastern side of San Francisco Bay. In Southern California, earthquakes

  11. Restrictions on the compatibility of equipment in archipelago countries: PERTAMINA experiences in Indonesia

    Being an archipelago state, the sea area of Indonesia is four times larger than its land area. Oil and natural gas play significant roles in the country's economic development. These activities at sea are showing signs of increasing, inevitably rendering the marine environment and living resources vulnerable to oil spills. Accidents, particularly grounding and collision occurrences in Malacca and the Singapore Straits sea lanes pose imminent threats. At PERTAMINA, the state-owned oil, gas and geothermal enterprise, oil spill contingency planning is entrusted to the Corporate Center for Environment Protection, Health and Safety. Marine activities are managed under the Directorate of Shipping, Harbour and Communication. In this paper oil spill response planning and coordination activities, which are based on the International Petroleum Industry Environmental Conservation Association (IPIECA) tiered preparedness concept, are described. The tiered preparedness concept addresses the limited availability of equipment, and incorporates specific response plans for each type of spill scenario (e.g. passing tanker, loading/unloading ship at terminal, major inland spill, etc), for each area of operation. It also specifies the type of equipment that must be available in the area to respond to the type of spill (using the concept of maximum credible spill in each case) that may occur in that area. 5 figs

  12. Genetic diversity and population structure of Plasmodium falciparum over space and time in an African archipelago.

    Salgueiro, Patrícia; Vicente, José Luís; Figueiredo, Rita Carrilho; Pinto, João

    2016-09-01

    The archipelago of São Tomé and Principe (STP), West Africa, has suffered the heavy burden of malaria since the 16th century. Until the last decade, when after a successful control program STP has become a low transmission country and one of the few nations with decreases of more than 90% in malaria admission and death rates. We carried out a longitudinal study to determine the genetic structure of STP parasite populations over time and space. Twelve microsatellite loci were genotyped in Plasmodium falciparum samples from two islands collected in 1997, 2000 and 2004. Analysis was performed on proportions of mixed genotype infections, allelic diversity, population differentiation, effective population size and bottleneck effects. We have found high levels of genetic diversity and minimal inter-population genetic differentiation typical of African continental regions with intense and stable malaria transmission. We detected significant differences between the years, with special emphasis for 1997 that showed the highest proportion of samples infected with P. falciparum and the highest mean number of haplotypes per isolate. This study establishes a comprehensive genetic data baseline of a pre-intervention scenario for future studies; taking into account the most recent and successful control intervention on the territory.

  13. A new species of Agelas from the Zanzibar Archipelago, western Indian Ocean (Porifera, Demospongiae).

    Manconi, Renata; Pronzato, Roberto; Perino, Erica

    2016-01-01

    A new sponge species (Demospongiae: Agelasida: Agelasidae) is described from the eastern coast of Unguja Island in the Zanzibar Archipelago. Agelas sansibarica sp. n. is compared to all other Agelas species described so far. The new species differs from its congeners mainly in its three categories of verticillate spicules (acanthostyles, acanthostrongyles, and acanthoxeas) and their sizes. Acanthostrongyles, well represented in the spicular complement, are an exclusive trait of the new species widening the morphological range of the genus. Summarizing on spicular complement and spicular morphotraits of 36 species belonging to the genus Agelas: i) 32 species show only acanthostyles from Indo-Pacific (n = 14), Atlantic (n = 17), and Mediterranean (n = 1); ii) three Indo-Pacific species show acanthostyles and acanthoxeas; iii) one species Agelas sansibarica sp. n. from the western Indian Ocean is characterised by the unique trait of three categories of verticillate spicules (acanthostyles, acanthostrongyles and acanthoxeas). A key for the Indo-Pacific species is supplied together with short descriptions, illustrations, and geographic range; literature on chemical bioprospecting of the genus Agelas is also provided.

    Persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and dibenzofurans (PCDFs), are ubiquitous environmental contaminants of which significant concentrations are reported in upper trophic level animals. In 1998, we collected blubber biopsy samples (n=11) from killer whales (Orcinus orca) inhabiting the coastal waters around Possession Island, Crozet Archipelago, southern Indian Ocean, for contaminant analyses. Despite inhabiting an isolated region far removed from industrial activities, these killer whales can presently be considered among the most PCB-contaminated cetaceans in the southern hemisphere, with concentrations ranging from 4.4 to 20.5mg/kg lipid weight (lw). PCDD levels ranged from below the detection limit (5 ng/kg) to 77.1 ng/kg lw and PCDF levels from below the detection limit (7 ng/kg) to 36.1 ng/kg lw. Over 70% of our study animals had PCB concentrations which exceeded a 1.3mg/kg PCB threshold established for endocrine disruption and immunotoxicity in free-ranging harbour seals, suggesting that organic contaminants cannot be ruled out as an additional threat to this declining population.

    2003-07-01

    Allele frequencies for 17 STR loci were analyzed in a sample of unrelated males from the Cabo Verde Archipelago. The samples were gathered in such a way that the origin of the subjects was perfectly identified, and they could be included in one of the leeward or windward groups of islands. This study reveals that there are significant differences between both groups of islands, and between Cabo Verdeans and other populations from sub-Sahara Africa including the Guineans, the most probable source population for Cabo Verdeans. This study confirms mtDNA data and, together with HLA and Y chromosome data already published, shows that the Cabo Verde population is sub-structured and atypical, diverging substantially from mainland sub-Saharan populations. Overall these differences are most probably due to admixture between sub-Saharan slaves brought into the islands and other settlers of European origin. In the absence of a clear indication of a different ethnic composition of the first sub-Saharan settlers of Cabo Verde, the differentiation exhibited in both groups of islands can be most probably be attributed to genetic drift.

    2014-06-22

    The impacts of glacial cycles on the geographical distribution and size of populations have been explored for numerous terrestrial and marine taxa. However, most studies have focused on high latitudes, with only a few focused on the response of biota to the last glacial maximum (LGM) in equatorial regions. Here, we examine how population sizes of key bee fauna in the southwest Pacific archipelagos of Fiji, Vanuatu and Samoa have fluctuated over the Quaternary. We show that all three island faunas suffered massive population declines, roughly corresponding in time to the LGM, followed by rapid expansion post-LGM. Our data therefore suggest that Pleistocene climate change has had major impacts across a very broad tropical region. While other studies indicate widespread Holarctic effects of the LGM, our data suggest a much wider range of latitudes, extending to the tropics, where these climate change repercussions were important. As key pollinators, the inferred changes in these bee faunas may have been critical in the development of the diverse Pacific island flora. The magnitude of these responses indicates future climate change scenarios may have alarming consequences for Pacific island systems involving pollinator-dependent plant communities and agricultural crops.

  17. Testing the island effect on phenotypic diversification: insights from the Hemidactylus geckos of the Socotra Archipelago

    Island colonization is often assumed to trigger extreme levels of phenotypic diversification. Yet, empirical evidence suggests that it does not always so. In this study we test this hypothesis using a completely sampled mainland-island system, the arid clade of Hemidactylus, a group of geckos mainly distributed across Africa, Arabia and the Socotra Archipelago. To such purpose, we generated a new molecular phylogeny of the group on which we mapped body size and head proportions. We then explored whether island and continental taxa shared the same morphospace and differed in their disparities and tempos of evolution. Insular species produced the most extreme sizes of the radiation, involving accelerated rates of evolution and higher disparities compared with most (but not all) of the continental groups. In contrast, head proportions exhibited constant evolutionary rates across the radiation and similar disparities in islands compared with the continent. These results, although generally consistent with the notion that islands promote high morphological disparity, reveal at the same time a complex scenario in which different traits may experience different evolutionary patterns in the same mainland-island system and continental groups do not always present low levels of morphological diversification compared to insular groups.

  18. Spatial distribution of oxygen-18 and deuterium in stream waters across the Japanese archipelago

    2014-09-01

    Full Text Available The spatial distribution of oxygen and hydrogen isotopic composition (δ18O and δ2H of stream waters across Japan was clarified with a data set compiling sample data obtained from 1278 forest catchments during the summer of 2003. Both δ18O and δ2H values showed positive correlations with the mean annual air temperature and annual evapotranspiration, and negative correlations with latitude and elevation. Deuterium excess (d excess values in stream waters were higher on the Sea of Japan side, and lower on the Pacific Ocean side, of the Japanese archipelago. The d excess in precipitation was generally higher in winter and lower in summer in Japan. The Sea of Japan side experiences a great deal of snowfall, and seasonal changes in monthly precipitation are rather small. In contrast, the Pacific Ocean side experiences a large amount of rainfall during summer with low levels of precipitation during the winter. Therefore, the lower d excess in stream waters on the Pacific Ocean side reflects summer precipitation, and the higher values on the Sea of Japan side are affected by delayed recharge from snowmelt. The isoscapes of stream water connote not only spatially integrated but also temporally integrated isotope signals of precipitation, and provide a framework for addressing applied hydrological, ecological, or meteorological research questions at regional scales, such as the effects of climate change.

    Following a global coral bleaching event in 1998, Acropora corals surrounding most of Okinawa island (OI) were devastated, although they are now gradually recovering. In contrast, the Kerama Islands (KIs) only 30 km west of OI, have continuously hosted a great variety of healthy corals. Taking advantage of the decoded Acropora digitifera genome and using genome-wide SNP analyses, we clarified Acropora population structure in the southern Ryukyu Archipelago (sRA). Despite small genetic distances, we identified distinct clusters corresponding to specific island groups, suggesting infrequent long-distance dispersal within the sRA. Although the KIs were believed to supply coral larvae to OI, admixture analyses showed that such dispersal is much more limited than previously realized, indicating independent recovery of OI coral populations and the necessity of local conservation efforts for each region. We detected strong historical migration from the Yaeyama Islands (YIs) to OI, and suggest that the YIs are the original source of OI corals. In addition, migration edges to the KIs suggest that they are a historical sink population in the sRA, resulting in high diversity. This population genomics study provides the highest resolution data to date regarding coral population structure and history. PMID:26656261

  20. Levels of organochlorine compounds in spotted dolphins from the Coiba archipelago, Panama.

    Borrell, A; Cantos, G; Pastor, T; Aguilar, A

    2004-02-01

    Blubber and skin samples from 63 spotted dolphins (Stenella attenuata) (18 males, 40 females and 5 of unknown sex) were collected by biopsy techniques in the waters of the Coiba archipelago. Blubber was analyzed for organochlorine compounds and skin for gender determination. Mean levels of HCB (hexachlorobenzene), tPCB (polychlorinated biphenyls) and tDDT (dichlorodiphenyltrichloroethane) were 0.064, 2.30 and 6.4 mgkg(-1), respectively. These levels are low and are not considered to represent a threat to the S. attenuata population. No significant differences either in concentrations of HCB, tPCB and tDDT or in PCB profiles were observed between males and females. The ratio tDDT/tPCB was 2.69, indicating predominantly agrarian versus industrial activities in the area. The ratio ppDDE/tDDT was 0.83, a high figure that suggests both a local reduction of DDT inputs and a high rate of DDT degradation. Significant quantitative and qualitative differences were observed between two schools, suggesting intra-population heterogeneity in organochlorine exposure possibly due to demographic segregation.

  1. Ocean variability around Cape Verde Archipelago from near real time satellite altimetry and SST images

    Lázaro, C.; Fernandes, M. J.

    2003-04-01

    In this work, the synergy of data acquired by the radar altimeter (RA) and the infrared radiometer (ATSR-2/IRR) aboard the ERS-2 satellite, presently available in near real time, is exploited. The aim is to extract valid oceanographic information for the characterisation of ocean circulation around the Cape Verde Archipelago (North Atlantic Ocean) and its seasonal variability. For the data acquisition period (June 2001 to May 2002, ERS-2 cycles 64 to 73), synoptic maps representing sea surface temperature (SST) and absolute dynamic topography (ADT) values for each cycle were created. The methodology adopted for the near real time data processing is described. As the accuracy of the orbit and geophysical corrections is a fundamental issue in the evaluation of altimetric data, the near real time products were compared with the OPR products, which have several months of latency. Based upon the ADT values, intensity and direction of surface geostrophic currents were calculated. The SST variability was investigated and compared with the absolute dynamic topography variability. The seasonal cycle of the oceanographic characteristics, as extracted from the combined analysis of the two variables, is perfectly visible along the year of study.

    2016-07-01

    We assessed evidence of exposure to viruses and bacteria in an unmanaged and long-isolated population of Soay sheep (Ovis aries) inhabiting Hirta, in the St Kilda archipelago, 65 km west of Benbecula in the Outer Hebrides of Scotland. The sheep harbour many metazoan and protozoan parasites but their exposure to viral and bacterial pathogens is unknown. We tested for herpes viral DNA in leucocytes and found that 21 of 42 tested sheep were infected with ovine herpesvirus 2 (OHV-2). We also tested 750 plasma samples collected between 1997 and 2010 for evidence of exposure to seven other viral and bacterial agents common in domestic Scottish sheep. We found evidence of exposure to Leptospira spp., with overall seroprevalence of 6·5%. However, serological evidence indicated that the population had not been exposed to border disease, parainfluenza, maedi-visna, or orf viruses, nor to Chlamydia abortus. Some sheep tested positive for antibodies against Mycobacterium avium subsp. paratuberculosis (MAP) but, in the absence of retrospective faecal samples, the presence of this infection could not be confirmed. The roles of importation, the pathogen-host interaction, nematode co-infection and local transmission warrant future investigation, to elucidate the transmission ecology and fitness effects of the few viral and bacterial pathogens on Hirta.

    2012-01-01

    This study examined the distribution of virioplankton and bacterioplankton in two coral reef systems (Ahe and Takaroa atolls) in the Tuamotu Archipelago, in comparison with the surrounding oligotrophic ocean. Mean concentrations of 4.8×10(5) and 6.2×10(5) cells ml(-1) for bacteria and 8.1×10(6) and 4.3×10(6) VLP(virus-like particle) ml(-1) were recorded in Ahe and Takaroa lagoons, respectively. Chlorophyll-a concentrations and dissolved organic matter were higher in Ahe whereas (3)H thymidine incorporation rates were higher in Takaroa. First data on lytic and lysogenic strategies of phages in coral reef environments were discussed in this paper. The fraction of visibly infected cells by viruses was negligible regardless of the lagoon station (mean=0.15%). However, the fraction of lysogenic cells ranged between 2.5% and 88.9%. Our results suggest that the distribution patterns of virioplankton are apparently not coupled to the spatial dynamics of the bacterioplankton communities. PMID:22284701

    2016-09-01

    The presence of zoonotic parasites in feral cats have been widely considered all over the world. In Gran Canaria (Macaronesian archipelago, Canary Islands, Spain) the number of feral cats has grown out of control in urban and rural areas. 48 of Felis catus captured in different Gran Canaria areas were studied. Animals were necropsied and several organs were systematically examined in order to collect and identify macroscopic parasites. In addition, coprological tests were done in 28 cats. There were no statistically significant differences in the prevalence rate among sex, age or capture area, showing an overall prevalence of helminths of 77.1%. The most common tapeworms were Dipylidium caninum (64.6%) and Taenia taeniaeformis (31.3%), followed by the nematodes Toxocara cati (20.8%), Ancylostoma tubaeforme (18.8%), Aelurostrongylusabstrusus (10.4%) and Trichuris vulpis (2.08%). We also find several eggs of Alaria alata in the small intestine of one cat (2.08%), being the first description of this trematode in cats in the Canary Islands. Aproximatelly, 40% of the studied cats harboured more than one parasite. High rates of zoonotic species found in these animals suggest the need of controling parasitic infections and preventive measures against them. PMID:27447205

    2013-02-01

    Full Text Available Novaya Zemlya Archipelago is the eastern boundary of the Barents Sea. Theplankton of this region have been less intensively studied than thoseof other Arctic areas. This study of the mesozooplankton assemblage of Moller Bay was conducted in August2010. The total mesozooplankton abundance and biomass ranged from 962to 2980 individuals m-3 (mean ± SD: 2263 ± 921 indiv.m-3 and from 12.3 to 456.6 mg dry mass m-3 (mean ± SD:192 ± 170 DM m-3 respectively. Copepods and appendicularians werethe most numerous groups with Oithona similis, Pseudocalanusspp.,Acartiaspp., Calanus glacialis and Oikopleura vanhoeffennibeing the most abundant and frequent. Mesozooplankton abundance tendedto decrease with depth, whereas an inverse pattern was observed for the totalbiomass. Total mesozooplankton biomass was negatively correlated with watertemperature and positively correlated with salinity and chlorophyll aconcentration. Comparison with previous data showed significant interannualvariations in the total zooplankton stock in this region that may be due todifferences in sampling seasons, climatic conditions and the distribution ofpotential food sources (phytoplankton and seabird colonies.

  6. The origins of ambient biological sound from coral reef ecosystems in the Line Islands archipelago.

    2014-04-01

    Although ambient biological underwater sound was first characterized more than 60 years ago, attributing specific components of ambient sound to their creators remains a challenge. Noise produced by snapping shrimp typically dominates the ambient spectra near tropical coasts, but significant unexplained spectral variation exists. Here, evidence is presented indicating that a discernible contribution to the ambient sound field over coral reef ecosystems in the Line Islands archipelago originates from the interaction of hard-shelled benthic macro-organisms with the coral substrate. Recordings show a broad spectral peak centered between 14.30 and 14.63 kHz, incoherently added to a noise floor typically associated with relatively "white" snapping shrimp sounds. A 4.6 to 6.2 dB increase of pressure spectral density level in the 11 to 17 kHz band occurs simultaneously with an increase in benthic invertebrate activity at night, quantified through time-lapse underwater photography. Spectral-level-filtered recordings of hermit crabs Clibanarius diugeti in quiet aquarium conditions reveal that transient sounds produced by the interaction between the crustaceans' carapace, shell, and coral substrate are spectrally consistent with Line Islands recordings. Coral reef ecosystems are highly interconnected and subtle yet important ecological changes may be detected quantitatively through passive monitoring that utilizes the acoustic byproducts of biological activity.

  7. Effects of fish stocking on ecosystem services: an overview and case study using the Stockholm Archipelago.

    Holmlund, Cecilia M; Hammer, Monica

    2004-06-01

    In this article, we focus on documented and possible effects of fish stocking in terms of ecosystem services. The increasing use of fish stocking between 1970 and 2000 in the semiurban setting of Stockholm archipelago, Sweden, is used as case study. The objective is to analyze this management practice from an ecosystem perspective, accounting for both the ecological and social context of releasing fish. The results show that enhancements of four native species (Salmo S. trutta, Salmo salar, Stizostedion lucioperca, and Anguilla anguilla) have dominated over new introductions of one nonnative species. (Oncorhynchus mykiss). The major objective has been to increase fish catches for local resource users. Involved stakeholders include three management agencies, one hydropower company, and several local sport fishing associations. Documented effects focus on recapture and production rates. However, our analysis suggests that additional positive or negative effects on biodiversity, food web dynamics, mobile links, or ecological information may also result, with possible consequences for the long-term provision of food, game, and aesthetic values. We conclude that a more adaptive and cooperative management approach could benefit from a deeper analysis of where, when, and what species is released, by whom, which stakeholders that use the fish and those ecosystem services the fish generate, and of the role of formal and informal institutions for monitoring and evaluating the success of releasing fish.

  8. Environmental factors affecting large-bodied coral reef fish assemblages in the Mariana Archipelago.

    Benjamin L Richards

    Full Text Available Large-bodied reef fishes represent an economically and ecologically important segment of the coral reef fish assemblage. Many of these individuals supply the bulk of the reproductive output for their population and have a disproportionate effect on their environment (e.g. as apex predators or bioeroding herbivores. Large-bodied reef fishes also tend to be at greatest risk of overfishing, and their loss can result in a myriad of either cascading (direct or indirect trophic and other effects. While many studies have investigated habitat characteristics affecting populations of small-bodied reef fishes, few have explored the relationship between large-bodied species and their environment. Here, we describe the distribution of the large-bodied reef fishes in the Mariana Archipelago with an emphasis on the environmental factors associated with their distribution. Of the factors considered in this study, a negative association with human population density showed the highest relative influence on the distribution of large-bodied reef fishes; however, depth, water temperature, and distance to deep water also were important. These findings provide new information on the ecology of large-bodied reef fishes can inform discussions concerning essential fish habitat and ecosystem-based management for these species and highlight important knowledge gaps worthy of additional research.

  9. Summertime community structure of intertidal macrobenthos in Changdao Archipelago, Shandong Province, China

    Wang, Xiaochen; Li, Xinzheng; Li, Baoquan; Wang, Hongfa

    2009-09-01

    The community structure of intertidal macrobenthos in Changdao Archipelago (north of Shandong Peninsula, between Bohai Bay and the northern Yellow Sea) was examined based on samples collected from 14 stations in five transects in June 2007. Three stations corresponding to high, medium and low tidal areas were set up for each transect. A total of 68 macrobenthic species were found in the research region, most of which belonged to Mollusca and Crustacea. The average abundance and biomass of the macrobenthos was 1 383 ind./m2 and 372.41 g/m2, respectively. The use of an arbitrary similarity level of 20% resulted in identification of five groups among the 14 stations in the research region. There were remarkable differences in the biomass, abundance and Shannon-Wiener diversity index of the different sediments. Specifically, the order of biomass was rocky shores > gravel > mud-sand > coarse sand > stiff mud, while the order of abundance was rocky shores > coarse sand > mud-sand > gravel > stiff mud, and that of the diversity index was mud-sand > gravel > stiff mud > rocky shores > coarse sand. The above results revealed that the sediment type was the most important factor affecting the structure of the macrobenthic community of the intertidal zone.

  11. Compact High Resolution SANS using very cold neutrons (VCN-SANS)

    SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

    The recovery of the biogas generated from sanitary landfills, associated to its energetic use has been widely discussed. Thus, this paper aims to estimate the potential production of electric energy from sanitary landfill Santo Andre-SP. The biogas production was estimated using the rate of deposition of solid wastes in the landfill, using some mathematical models with parameters suggested by two models: LanGEM-USEPA (conventional landfill) and Word Bank. These results indicate that the potential of biogas production will be approximately 11 x 10{sup 6} Kg of methane/year in 2017 and production of electric energy in that year will be approximately 32,000 MWh, considering an of 75% over collection of biogas.

  19. Estimates of tidal mixing in the Indonesian archipelago from multidisciplinary INDOMIX in-situ data

    Koch-Larrouy, Ariane; Atmadipoera, Agus; van Beek, Pieter; Madec, Gurvan; Aucan, Jérôme; Lyard, Florent; Grelet, Jacques; Souhaut, Marc

    2015-12-01

    The Indonesian Mixing program (INDOMIX) was designed to quantify the very strong mixing that transforms Pacific waters into isohaline Indonesian Waters in the Indonesian archipelago. The turbulent dissipation rates and associated mixing were estimated and analyzed using a multidisciplinary approach that combines physical and geochemical in-situ observations: (1) direct measurements of the dissipation using a microstructure profiler, (2) use of density-based fine-scale methods applied to CTD and XCTD data, and (3) study of the vertical distribution of natural radionuclides (radium isotopes and actinium-227). Data were collected at five contrasting stations within the Indonesian archipelago, found above energetic straits or in relatively quiescent large basins. Strong instabilities, inversions of the density profiles and a very strong water mass transformation were observed. A wide range of dissipation values were obtained (between [10-10, 10-4] W kg-1) with spots of higher dissipation in the ocean interior correlated with a strong internal tide signal. Both the fine-scale and micro-scale methods allow us to identify very strong energy dissipation levels above the straits, ranging between [10-7, 10-4] W kg-1, in contrast to lower values at stations further away from the generation sites. The dissipation for the station located in the center of the Halmahera Sea ([10-9, 10-8] W kg-1) is stronger than for the Banda station ([10-11, 10-10] W kg-1), which is even further away from the generation sites. The three approaches agree relatively well and provide vertical eddy diffusivities values ranging between 5×10-4 and 5×10-1 m2 s-1, except in the Banda Sea where values are similar to the ones found in the open ocean (10-6 m2 s-1). CTD and XCTD profilers (deployed between stations) give estimates of dissipation all along the transit. It is found that enhanced mixing occurs preferentially above rough topography, such as in the Ombai Strait, the Halmahera Sea's northern

  20. Facies, Stratigraphic and Depositional Model of the Sediments in the Abrolhos Archipelago (Bahia, BRAZIL)

    Matte, R. R.; Zambonato, E. E.

    2012-04-01

    Located in the Mucuri Basin on the continental shelf of southern Bahia state, northeast Brazil, about 70 km from the city of Caravelas,the Abrolhos archipelago is made up of five islands; Santa Barbara, Redonda, Siriba, Guarita and Sueste. The exhumed sediments in the Abrolhos archipelago are a rare record of the turbidite systems which fill the Brazilian Atlantic Basin, and are probably an unprecedented example of a plataform turbidite system (Dr. Mutti, personal communication). Despite the limited area, the outcrops display a wide facies variation produced by different depositional processes, and also allow for the observation of the layer geometries. Associated with such sedimentary rocks, the Abrolhos Volcanic Complex belongs stratigraphically to the Abrolhos Formation. These igneous rocks were dated by the Ar / Ar method, with ages ranging from 60 to 40 My, placing such Volcanic Complex between the Paleocene and Eocene. The sedimentary section is best exposed in the Santa Barbara and Redonda islands and altogether it is 70 m thick. The measured vertical sections show a good stratigraphic correlation between the rocks of the western portion of the first island and those of Redonda Island. However, there is no correlation between the eastern and western portions of Santa Barbara Island, since they are very likely interrupted by the igneous intrusion and possibly by faulting. The sedimentary stack consists of deposits with alternated regressive and transgressive episodes interpreted as high frequency sequences. The coarse facies, sandstones and conglomerates, with abrupt or erosive bases record regressive phases. On the other hand, finer sandstones and siltstones facies, which are partly bioturbated, correspond to phases of a little sediment supply. In the central and eastern portions of Santa Barbara Island, there is a trend of progradational stacking, while both in the western portion of Santa Barbara and in Redonda islands an agradational trend is observed

    Mesoamerican peoples had a long history of cacao use—spanning more than 34 centuries—as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, an...

  4. Arctic environments and global change: Evidence in deep permafrost temperatures, Canadian arctic archipelago

    In considering the role of the polar regions in future global change, one may look toward these regions for evidence of past environmental change. Deep ground temperatures provide one window on past surface temperatures, which may be interpreted in terms not only of past climate but also of past environmental conditions. Across the Canadian Arctic Archipelago, there is no consistent curvature in deep ground temperature profiles that can be modeled in terms of warming of the past century. This contrasts with the result reported by Lachenbruch et al. [1986] for the Prudhoe Bay area of Alaska and may be a consequence of the much larger region and wider well spacing considered in the Canadian case. Any curvature present varies from well to well and may be interpreted in terms of surface temperature changes of the order of 1-3 K on the scale of decades to centuries. However, there is some evidence that these surface temperature histories may arise from long-term changes in paleoenvironmental factors as well as climate. For instance, the paleoclimate derived from oxygen isotope data at the Agassiz Ice Cap has been compared with the geothermal signature at a well some 180 km to the west. For the Little Ice Age (LIA), the Agassiz paleoclimate explains only half the measured variation in ground temperatures at the geothermal site; the remaining variation may be due to other environmental effects, such as an increase in snow cover following the LIA. This is consistent with extrapolated surface temperatures 7 K higher than other Arctic sites and the unusually deep snow cover observed today

  5. Macrophytobenthic flora of the Abrolhos Archipelago and the Sebastião Gomes Reef, Brazil

    Torrano-Silva, Beatriz N.; Oliveira, Eurico C.

    2013-11-01

    The Abrolhos Bank, located on the coast of Bahia, Brazil, harbors the largest coral reef system in the South Atlantic. This area has attracted the attention of biologists because of its peculiar mushroom-shaped structures, locally known as "chapeirões", and endemic species of corals and other organisms. The macrophytobenthos compartment plays an important ecological role in the functioning of the bank, and some reports on the presence of seaweeds and seagrasses have been published; however, the data are fragmentary, and a more detailed survey of the macrophytobenthos compartment is lacking. Here we consolidate the information available and add new data obtained from two expeditions focused on seaweed and seagrass diversity from two sectors of the bank: the islands of the Abrolhos archipelago (AA) and the Sebastião Gomes Reef (SG). These sites were selected for their contrasting characteristics. Specifically, SG (15 km off the mouth of the Caravelas River) is subjected to a broader range of anthropogenic impacts and to input of terrigenous sediments, while the AA (54 km offshore) is surrounded by calcareous biogenic sediments, has clearer water and is less affected by human activities. Macrophytobenthic species richness on both reference areas is larger than previously thought. Considering previous records, there are 164 species of macrophytes in AA and 111 species in SG, of which 59 and 74 species are first records for each respective location. The higher species richness at the AA may result from a higher habitat complexity and lower turbidity, but a potential negative effect of enhanced human impacts at SG cannot be ruled out. Considering that macroalgae are relevant components of the benthic community, as producers and structurer organisms, the data presented herein provide a reliable baseline for future environmental studies, and thus may contribute to improve management policies within the unique ecosystem of Abrolhos.

  6. Winds of time: Lessons from Utö in the Stockholm Archipelago, 1990–2001

    When investigating the success or failure of different wind power projects, it is essential to take into account how they were historically situated. This study focuses on attempts to develop wind power in an archipelago setting, at Utö in Sweden. It has been argued that the development of Swedish wind power slowed during the 1990s; by revisiting the early days of wind power, looking at resistance and support, and connecting success factors, this can be further investigated. Whereas earlier research pointed out institutional conditions and site-specific conditions as crucial for successful wind power development and acceptance, the picture can be made more complete by discussing how wind power projects are affected by time-specific historical conditions. In the case of Utö, these can partly be associated with a newly launched political support program that gave the project political legitimacy and added a “pioneering spirit” to the endeavor. Conversely, when wind power is not seen as “pioneering” or “experimental” any more, but as a mere industrial activity, other incentives may need to be offered to municipalities. -- Highlights: •When evaluating wind power projects, the historical context is important to complement the picture. •The case of Utö is tells important lessons of the Swedish early 1990s. •Success factors in this case: political legitimacy, local support, pioneering spirit, promising technology. •This wind power establishment was not seen as a threat to recreation or landscape. •Lessons for today: how to deal with socio-political acceptance when wind power becomes “industrial”

  7. Satellite SST-Based Coral Disease Outbreak Predictions for the Hawaiian Archipelago

    Full Text Available Predicting wildlife disease risk is essential for effective monitoring and management, especially for geographically expansive ecosystems such as coral reefs in the Hawaiian archipelago. Warming ocean temperature has increased coral disease outbreaks contributing to declines in coral cover worldwide. In this study we investigated seasonal effects of thermal stress on the prevalence of the three most widespread coral diseases in Hawai’i: Montipora white syndrome, Porites growth anomalies and Porites tissue loss syndrome. To predict outbreak likelihood we compared disease prevalence from surveys conducted between 2004 and 2015 from 18 Hawaiian Islands and atolls with biotic (e.g., coral density and abiotic (satellite-derived sea surface temperature metrics variables using boosted regression trees. To date, the only coral disease forecast models available were developed for Acropora white syndrome on the Great Barrier Reef (GBR. Given the complexities of disease etiology, differences in host demography and environmental conditions across reef regions, it is important to refine and adapt such models for different diseases and geographic regions of interest. Similar to the Acropora white syndrome models, anomalously warm conditions were important for predicting Montipora white syndrome, possibly due to a relationship between thermal stress and a compromised host immune system. However, coral density and winter conditions were the most important predictors of all three coral diseases in this study, enabling development of a forecasting system that can predict regions of elevated disease risk up to six months before an expected outbreak. Our research indicates satellite-derived systems for forecasting disease outbreaks can be appropriately adapted from the GBR tools and applied for a variety of diseases in a new region. These models can be used to enhance management capacity to prepare for and respond to emerging coral diseases throughout Hawai

  8. Summertime sources of dimethyl sulfide in the Canadian Arctic Archipelago and Baffin Bay

    Dimethyl sulfide (DMS) plays a major role in the global sulfur cycle. In addition, its atmospheric oxidation products contribute to the formation and growth of atmospheric aerosol particles, thereby influencing cloud condensation nuclei (CCN) populations and thus cloud formation. The pristine summertime Arctic atmosphere is a CCN-limited regime, and is thus very susceptible to the influence of DMS. However, atmospheric DMS mixing ratios have only rarely been measured in the summertime Arctic. During July-August 2014, we conducted the first high time resolution (10 Hz) DMS mixing ratio measurements for the Eastern Canadian Archipelago and Baffin Bay as one component of the Network on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environments (NETCARE). DMS mixing ratios ranged from below the detection limit of 4 to 1155 pptv (median 186 pptv). A set of transfer velocity parameterizations from the literature coupled with our atmospheric and coincident seawater DMS measurements yielded air-sea DMS flux estimates ranging from 0.02-12 μmol m-2 d-1, the first published for this region in summer. Airmass trajectory analysis using FLEXPART-WRF and chemical transport modeling using GEOS-Chem indicated that local sources (Lancaster Sound and Baffin Bay) were the dominant contributors to the DMS measured along the 21 day ship track, with episodic transport from the Hudson Bay System. After adjusting GEOS-Chem oceanic DMS values in the region to match measurements, GEOS-Chem reproduced the major features of the measured time series, but remained biased low overall (median 67 pptv). We investigated non-marine sources that might contribute to this bias, such as DMS emissions from lakes, biomass burning, melt ponds and coastal tundra. While the local marine sources of DMS dominated overall, our results suggest that non-local and possibly non-marine sources episodically contributed strongly to the observed summertime Arctic DMS mixing ratios.

  9. Recent changes in the multi-year ice area budget of the Canadian Arctic Archipelago

    Howell, Stephen; Pizzolato, Larissa; Derksen, Chris; Brady, Michael

    2014-05-01

    The Canadian Arctic Archipelago (CAA) is intricate collection of islands and channels located on the North American continental shelf. The deep-water route of the North West Passage crosses through the CAA near 75°N connecting the Atlantic and Pacific Oceans. The major challenge to safe navigation of the North West Passage is the presence of multi-year sea ice (MYI). In recent years, MYI conditions within the CAA during September have begun to decrease considerably with 2011 and 2012 being the lightest MYI years on record since 1968. Recent light MYI years within the CAA are associated with recent openings of the North West Passage (i.e. 2007, 2008, 2010, 2011 and 2012). MYI within the CAA is either imported from the Arctic Ocean or grown in situ and therefore in order to understand the processes contributing to these recent reductions in September MYI within the CAA we derived the first estimates of the MYI area budget of the CAA using RADARSAT-1 and RADARSAT-2 imagery from 1997-2012. Overall, there has been a reduced amount of Arctic Ocean MYI inflow into the CAA during the summer months since 2007. The latter process can be attributed to more frequent high sea level pressure anomalies over the Beaufort Sea and Canadian Basin. The amount of MYI grown in situ within the CAA has also reduced because of longer melt seasons reducing the survivability of seasonal ice over. MYI outflow to Baffin Bay from the CAA has been relatively consistent over the period. Interestingly, the recent reduced amount of MYI within the CAA, particularly noticeable since 2007, was found to be quantitatively linked with a step change increase in observed Arctic marine shipping activity following the dramatic summer sea ice reductions that began in 2007.

  10. New Ulvaceae (Ulvophyceae, Chlorophyta) from mesophotic ecosystems across the Hawaiian Archipelago.

    2016-02-01

    Ulvalean algae (Chlorophyta) are most commonly described from intertidal and shallow subtidal marine environments worldwide, but are less well known from mesophotic environments. Their morphological simplicity and phenotypic plasticity make accurate species determinations difficult, even at the generic level. Here, we describe the mesophotic Ulvales species composition from 13 locations across 2,300 km of the Hawaiian Archipelago. Twenty-eight representative Ulvales specimens from 64 to 125 m depths were collected using technical diving, submersibles, and remotely operated vehicles. Morphological and molecular characters suggest that mesophotic Ulvales in Hawaiian waters form unique communities comprising four species within the genera Ulva and Umbraulva, each with discrete geographic and/or depth-related distributional patterns. Three genetically distinct taxa are supported by both plastid (rbcL and tufA) and nuclear (ITS1) markers, and are presented here as new species: Umbraulva kaloakulau, Ulva ohiohilulu, and Ulva iliohaha. We also propose a new Umbraulva species (Umbraulva kuaweuweu), which is closely related to subtidal records from New Zealand and Australia, but not formally described. To our knowledge, these are the first marine species descriptions from Hawai'i resulting from the collaboration of traditional Hawaiian nomenclature specialists, cultural practitioners and scientists. The difficulty of finding reliable diagnostic morphological characters for these species reflects a common problem worldwide of achieving accurate identification of ulvalean taxa using solely morphological criteria. Mesophotic Ulvales appear to be distinct from shallow-water populations in Hawai'i, but their degree of similarity to mesophotic floras in other locations in the Pacific remains unknown.

    Full Text Available This article examines the “sense of beauty” in the United States imperial archipelago, composed of the island territories of Cuba, Hawai`i, Philippines, and Puerto Rico, all acquired in 1898. The theoretical connection among these two elements –aesthetics and empire– is provided by a revision of the concepts “economy of colonial desire” and “complex of visuality.” This paper analyzes the most advanced visual technology of the late nineteenth century: the mass- produced, printed photograph. In particular, it focuses upon the representations of feminine beauty as found the illustrated “new-possessions” books which described recent island acquisitions of the United States. The connections between aesthetics and the forms of governance in each territory will also be elucidated.Este artículo examina el “sentido de belleza” en el archipiélago imperial estadounidense, compuesto de los territorios isleños de Cuba, Hawai`i, Filipinas y Puerto Rico, todos adquiridos en 1898.

  12. Flowing Direction Determined Using Ams Technique On Volcanic Sections From The Kerguelen Archipelago.

    Plenier, G.; Camps, P.; Henry, B.

    Lava flows are known to present a low degree of anisotropy on the contrary of their rel- atively high magnetic susceptibility. AMS measurements thus provide scattered results and a large number of sample is needed to well define the mean directions. Moreover, local disturbances of flowing can switch the maximum and intermediate principal di- rections and can lead to erroneous interpretations. Despite theses difficulties, this study aim to determine flowing direction of five sections (a hundred lava flows) from the Ker- guelen archipelago using the Anisotropy of Magnetic Susceptibility (AMS) technique and complete regional geological observations of Nougier (1970). Primarily sampled for paleosecular variation and paleointensity study, 7 samples per units were mea- sured using Kappabridges KLY2 and KLY3 at St Maur des Fosses and Montpellier, respectively. To limit the effect of flowing disturbances, we grouped all the lava flow in each section. We also filtered the data using F statistics, in order to remove statisti- cally indistinct directions and the three sigma limit on the A and B parameter defined by Canon Tapia et al. (1995). The mean directions of each section are obtained using tensor averaging method (Hext 1963, Jelinek 1978). The different confidence regions about the susceptibility axis, determined by means of linear perturbation analysis (Je- linek 1978, Lienert 1991), bootstrap method (Constable and Tauxe 1990) and bivariate extension of Fisher statistics (Henry and Le Goff 1995), are compared. Density plots of each mean direction and all combined are also used for interpretations. The study is still on progress. Our preliminary results provided coherent flowing directions and favor the use of AMS technique on lava flows if carefully interpreted.

  13. Towards Stochastic Optimization-Based Electric Vehicle Penetration in a Novel Archipelago Microgrid.

    Yang, Qingyu; An, Dou; Yu, Wei; Tan, Zhengan; Yang, Xinyu

    2016-01-01

    Due to the advantage of avoiding upstream disturbance and voltage fluctuation from a power transmission system, Islanded Micro-Grids (IMG) have attracted much attention. In this paper, we first propose a novel self-sufficient Cyber-Physical System (CPS) supported by Internet of Things (IoT) techniques, namely "archipelago micro-grid (MG)", which integrates the power grid and sensor networks to make the grid operation effective and is comprised of multiple MGs while disconnected with the utility grid. The Electric Vehicles (EVs) are used to replace a portion of Conventional Vehicles (CVs) to reduce CO 2 emission and operation cost. Nonetheless, the intermittent nature and uncertainty of Renewable Energy Sources (RESs) remain a challenging issue in managing energy resources in the system. To address these issues, we formalize the optimal EV penetration problem as a two-stage Stochastic Optimal Penetration (SOP) model, which aims to minimize the emission and operation cost in the system. Uncertainties coming from RESs (e.g., wind, solar, and load demand) are considered in the stochastic model and random parameters to represent those uncertainties are captured by the Monte Carlo-based method. To enable the reasonable deployment of EVs in each MGs, we develop two scheduling schemes, namely Unlimited Coordinated Scheme (UCS) and Limited Coordinated Scheme (LCS), respectively. An extensive simulation study based on a modified 9 bus system with three MGs has been carried out to show the effectiveness of our proposed schemes. The evaluation data indicates that our proposed strategy can reduce both the environmental pollution created by CO 2 emissions and operation costs in UCS and LCS. PMID:27322281

    2012-11-01

    Full Text Available The Regional Ocean Modeling System (ROMS was used to simulate the Indonesian Archipelago Sea current and temperature with two different vertical mixing schemes. One corresponds to the newly developed K-Profile Parameterization (KPP scheme and the other is adapted from the stability frequency of Brunt-Vaisala Frequency mixing (BVF. It is found that, both of schemes produce reasonably realistic sea surface temperature (SST; however, the root mean square error (RMSE values from the BVF vertical mixing were less than the KPP vertical mixing. The RMSE values from the BVF vertical mixing at northwest and southeast monsoons can be reduced down to 5.1607E-01 0C and 5.7639E-01 0C respectively. These validation results reveal that accuracy of the BVF vertical mixing is better than the KPP vertical mixing.The model results based on the BVF vertical mixing scheme show that the direction of Java Sea, Karimata and Sunda Straits surface current are strongly affected by the zonal wind system. The direction of surface current was change following the monsoonal wind system. On the other hand, the Makasar Strait surface current tend to flow southward throughout the year with annual variations in transport are related dynamically to the monsoon winds. These southward surface currents are known as Indonesian Through Flow (ITF and it is governed by strong pressure gradient from the Pacific to the Indian Oceans. The signals of El Nino 2002 event also can be detected by the model results. It recognized that the strong Equatorial Counter Current flows to eastward to the central part of the Pacific Ocean. The Makasar Strait surface current was stronger than usual but the Karimata Strait surface current was weaker during this period.

  15. Patterns of coral disease across the Hawaiian archipelago: relating disease to environment.

    Greta S Aeby

    Full Text Available In Hawaii, coral reefs occur across a gradient of biological (host abundance, climatic (sea surface temperature anomalies and anthropogenic conditions from the human-impacted reefs of the main Hawaiian Islands (MHI to the pristine reefs of the northwestern Hawaiian Islands (NWHI. Coral disease surveys were conducted at 142 sites from across the Archipelago and disease patterns examined. Twelve diseases were recorded from three coral genera (Porites, Montipora, Acropora with Porites having the highest prevalence. Porites growth anomalies (PorGAs were significantly more prevalent within and indicative of reefs in the MHI and Porites trematodiasis (PorTrm was significantly more prevalent within and indicative of reefs in the NWHI. Porites tissue loss syndrome (PorTLS was also important in driving regional differences but that relationship was less clear. These results highlight the importance of understanding disease ecology when interpreting patterns of disease occurrence. PorTrm is caused by a parasitic flatworm that utilizes multiple hosts during its life cycle (fish, mollusk and coral. All three hosts must be present for the disease to occur and higher host abundance leads to higher disease prevalence. Thus, a high prevalence of PorTrm on Hawaiian reefs would be an indicator of a healthy coral reef ecosystem. In contrast, the high occurrence of PorGAs within the MHI suggests that PorGAs are related, directly or indirectly, to some environmental co-factor associated with increased human population sizes. Focusing on the three indicator diseases (PorGAs, PorTrm, PorTLS we used statistical modeling to examine the underlying associations between disease prevalence and 14 different predictor variables (biotic and abiotic. All three diseases showed positive associations with host abundance and negative associations with thermal stress. The association with human population density differed among disease states with PorGAs showing a positive and Por

  16. The volcanic-subvolcanic rocks of the fernando de noronha archipelago, southern atlantic ocean: Mineral chemistry

    Lopes, Rosana; Ulbrich, Mabel; Ulbrich, Horstpeter

    2014-12-01

    Fernando de Noronha archipelago presents an older Remédios Formation with subvolcanic intrusions, belonging to two different alkaline series, the sodic (undersaturated: basanites, tephrites, essexites, tephriphonolites, phonolites), and potassic ones (mildly undersaturated to silicic, with alkali basalts, basaltic trachyandesites, trachyandesites, trachytes), and lamprophyres. The upper Quixaba Formation presents nephelinite flows and basanites. A third minor unit, São José, is constituted by basanites carrying mantle xenoliths. Magnesian olivines occur in the Remédios basanites and alkali basalts, and in nephelinites. Melilites are present as groundmass grains in melilite melanephelinites (MEM). Clinopyroxenes (cpx) are mostly salites to titaniferous salites (Remédios sodic series), grading into aegirines in the differentiated aphyric phonolites. Cpx in the lamprophyres show disequilibrium textures. In the Quixaba flows, cpx are salites, enriched in Mg (especially in MEM). Amphiboles, remarkably, are common in tephriphonolites and phonolites and in basaltic trachyandesites, sometimes with disequilibrum zoning textures, and a conspicuous phase in lamprophyres. Dark micas are present as groundmass plates in MEM, OLM and PYM (olivine and pyroxene melanephelinites), with compositional variety (enriched in Ti, Ba, Sr) depending on the composition of the parent rock; BaO can be as high as 16-19%. Feldspars crystallize as calcic plagioclases, sanidines and anorthoclases, depending on the rock types, as phenocrysts and in groundmass, both in Quixaba and Remédios rocks; they are absent in nephelinites. Nephelines are found in Remédios sodic series types and Quixaba rocks. Haüyne and noseane are rarely observed in Remédios rocks.

  17. Sea level changes during the last and present interglacials in Sal Island (Cape Verde archipelago)

    Last interglacial and Holocene deposits are particularly well developed in the southern parts of Sal Island (Cape Verde Archipelago). They primarily consist of low-elevation (≤ 2 m above sea level [a.s.l.]) marine deposits made of a basal conglomerate embedded in carbonate mud, passing upwards to calcarenites. All deposits contain an abundant fauna with corals, algae and molluscs with Strombus latus Gmelin and accompanying warm water species of the "Senegalese" fauna. Small scale geomorphological mapping with detailed morphosedimentary analysis revealed lateral facies changes and imbricate (offlapping) structures that suggest small-scale oscillations of paleo-sealevels during high sea stand intervals. U-series measurements (in coral fragments) allowed unequivocal identification of Marine Isotope Substage (MIS) 5.5 units, but were not precise enough to date the sea level oscillations of the interval. However, geomorphological data and sedimentary facies analysis suggest a double sea level highstand during the peak of the last interglacial. MIS 5.5 age deposits occur at Sal and the Canary Islands at low topographic elevations, between 1 and 2 masl. However, these values are lower than the elevations measured for the correlative terraces outcropping at the western tropical Atlantic islands, widely considered to be tectonically stable. Combining the results in this paper with earlier investigations of the "Senegalese" fauna distribution as far north as the Mediterranean basin, it is suggested that the last-interglacial oceanic temperatures in this basin, as well as the temperatures in other islands of the Eastern Atlantic and the coasts of Morocco, were warmer than modern temperatures.

    2016-07-01

    Observed and modelled landfast ice thickness variability and trends spanning more than 5 decades within the Canadian Arctic Archipelago (CAA) are summarized. The observed sites (Cambridge Bay, Resolute, Eureka and Alert) represent some of the Arctic's longest records of landfast ice thickness. Observed end-of-winter (maximum) trends of landfast ice thickness (1957-2014) were statistically significant at Cambridge Bay (-4.31 ± 1.4 cm decade-1), Eureka (-4.65 ± 1.7 cm decade-1) and Alert (-4.44 ± 1.6 cm -1) but not at Resolute. Over the 50+-year record, the ice thinned by ˜ 0.24-0.26 m at Cambridge Bay, Eureka and Alert with essentially negligible change at Resolute. Although statistically significant warming in spring and fall was present at all sites, only low correlations between temperature and maximum ice thickness were present; snow depth was found to be more strongly associated with the negative ice thickness trends. Comparison with multi-model simulations from Coupled Model Intercomparison project phase 5 (CMIP5), Ocean Reanalysis Intercomparison (ORA-IP) and Pan-Arctic Ice-Ocean Modeling and Assimilation System (PIOMAS) show that although a subset of current generation models have a "reasonable" climatological representation of landfast ice thickness and distribution within the CAA, trends are unrealistic and far exceed observations by up to 2 orders of magnitude. ORA-IP models were found to have positive correlations between temperature and ice thickness over the CAA, a feature that is inconsistent with both observations and coupled models from CMIP5.

  1. Insecticide susceptibility of Aedes aegypti populations from Senegal and Cape Verde Archipelago

    2012-10-01

    Full Text Available Abstract Background Two concomitant dengue 3 (DEN-3 epidemics occurred in Cape Verde Archipelago and Senegal between September and October 2009. Aedes aegypti was identified as the vector of these epidemics as several DEN-3 virus strains were isolated from this species in both countries. The susceptibility to pyrethroids, organochlorine, organophosphates and carbamate was investigated in two field strains of Aedes aegypti from both countries using WHO diagnostic bioassay kits in order to monitor their the current status of insecticide susceptibility. Findings The two tested strains were highly resistant to DDT. The Cape Verde strain was found to be susceptible to all others tested insecticides except for propoxur 0.1%, which needs further investigation. The Dakar strain was susceptible to fenitrothion 1% and permethrin 0.75%, but displayed reduced susceptibility to deltamethrin, lambda-cyhalothrin and propoxur. Conclusions As base-line results, our observations stress a careful management of insecticide use for the control of Ae. aegypti. Indeed, they indicate that DDT is no longer efficient for the control of Ae. aegypti populations in Cape Verde and Dakar and further suggest a thorough follow-up of propoxur susceptibility status in both sites and that of deltamethrin and lambda-cyhalothrin in Ae. aegypti populations in Dakar. Thus, regular monitoring of susceptibility is greatly needed as well as the knowing if this observed resistance/susceptibility is focal or not and for observed resistance, the use of biochemical methods is needed with detailed comparison of resistance levels over a large geographic area.

  6. Diversity and distribution of symbiodinium associated with seven common coral species in the Chagos Archipelago, central Indian Ocean.

    Sung-Yin Yang

    Full Text Available The Chagos Archipelago designated as a no-take marine protected area in 2010, lying about 500 km south of the Maldives in the Indian Ocean, has a high conservation priority, particularly because of its fast recovery from the ocean-wide massive coral mortality following the 1998 coral bleaching event. The aims of this study were to examine Symbiodinium diversity and distribution associated with scleractinian corals in five atolls of the Chagos Archipelago, spread over 10,000 km(2. Symbiodinium clade diversity in 262 samples of seven common coral species, Acropora muricata, Isopora palifera, Pocillopora damicornis, P. verrucosa, P. eydouxi, Seriatopora hystrix, and Stylophora pistillata were determined using PCR-SSCP of the ribosomal internal transcribed spacer 1 (ITS1, PCR-DDGE of ITS2, and phylogenetic analyses. The results indicated that Symbiodinium in clade C were the dominant symbiont group in the seven coral species. Our analysis revealed types of Symbiodinium clade C specific to coral species. Types C1 and C3 (with C3z and C3i variants were dominant in Acroporidae and C1 and C1c were the dominant types in Pocilloporidae. We also found 2 novel ITS2 types in S. hystrix and 1 novel ITS2 type of Symbiodinium in A. muricata. Some colonies of A. muricata and I. palifera were also associated with Symbiodinium A1. These results suggest that corals in the Chagos Archipelago host different assemblages of Symbiodinium types then their conspecifics from other locations in the Indian Ocean; and that future research will show whether these patterns in Symbiodinium genotypes may be due to local adaptation to specific conditions in the Chagos.

  7. Applying Fishers' ecological knowledge to construct past and future lobster stocks in the Juan Fernandez Archipelago, Chile.

    Tyler D Eddy

    Full Text Available Over-exploited fisheries are a common feature of the modern world and a range of solutions including area closures (marine reserves; MRs, effort reduction, gear changes, ecosystem-based management, incentives and co-management have been suggested as techniques to rebuild over-fished populations. Historic accounts of lobster (Jasus frontalis on the Chilean Juan Fernández Archipelago indicate a high abundance at all depths (intertidal to approximately 165 m, but presently lobsters are found almost exclusively in deeper regions of their natural distribution. Fishers' ecological knowledge (FEK tells a story of serial depletion in lobster abundance at fishing grounds located closest to the fishing port with an associated decline in catch per unit effort (CPUE throughout recent history. We have re-constructed baselines of lobster biomass throughout human history on the archipelago using historic data, the fishery catch record and FEK to permit examination of the potential effects of MRs, effort reduction and co-management (stewardship of catch to restore stocks. We employed a bioeconomic model using FEK, fishery catch and effort data, underwater survey information, predicted population growth and response to MR protection (no-take to explore different management strategies and their trade-offs to restore stocks and improve catches. Our findings indicate that increased stewardship of catch coupled with 30% area closure (MR provides the best option to reconstruct historic baselines. Based on model predictions, continued exploitation under the current management scheme is highly influenced by annual fluctuations and unsustainable. We propose a community-based co-management program to implement a MR in order to rebuild the lobster population while also providing conservation protection for marine species endemic to the Archipelago.

  8. Changing Use Patterns, Changing Feedback Links: Implications for Reorganization of Coastal Fisheries Management in the Stockholm Archipelago, Sweden

    Maria Åqvist Almlöv

    2006-12-01

    Full Text Available Property rights are important institutions for regulating the use of valuable natural resources from coastal ecosystems. In this case study, we identify and analyze property rights and user patterns related to small-scale coastal fisheries in the Stockholm Archipelago, Sweden. User patterns and user groups have changed significantly over the last century, as commercial fishing has been increasingly replaced by recreational activities. Interviews with local resource users and owners of water properties in two different areas, Möja and Ornö parishes within the Stockholm Archipelago, revealed a very diverse pattern of property and user rights, with a large number of water and fishing rights owners. Recreational fisheries, including both sport and household fishing, seem to predominate in both areas, but ownership differs. In Möja, most waters are collectively owned, whereas in Ornö, individual ownership predominates. Very few examples of local influence on fisheries management were found in either area, although the social structure for joint management does exist in Möja. Instead, larger-scale institutions at the regional, national, or international level regulate fisheries, often not addressing local conditions and fish populations. The ongoing shift in resource use has created a heterogeneous user group, and the limitations of centralized management authorities in dealing with the diversity in the coastal ecosystem have created mismatches within the social–ecological system. Combined with a large-scale decline in coastal fish stocks, these mismatches challenge the existing local property rights arrangements as well as the more centralized regulatory management structure. A key issue for fisheries management is how to develop and stimulate appropriate distribution of management functions at different geographical scales and organizational levels. The complexity and diversity in archipelago fisheries call for multilevel arrangements and

  9. A complex evolutionary history in a remote archipelago: phylogeography and morphometrics of the Hawaiian endemic Ligia isopods.

    Carlos A Santamaria

    Full Text Available Compared to the striking diversification and levels of endemism observed in many terrestrial groups within the Hawaiian Archipelago, marine invertebrates exhibit remarkably lower rates of endemism and diversification. Supralittoral invertebrates restricted to specific coastal patchy habitats, however, have the potential for high levels of allopatric diversification. This is the case of Ligia isopods endemic to the Hawaiian Archipelago, which most likely arose from a rocky supralittoral ancestor that colonized the archipelago via rafting, and diversified into rocky supralittoral and inland lineages. A previous study on populations of this isopod from O'ahu and Kaua'i revealed high levels of allopatric differentiation, and suggested inter-island historical dispersal events have been rare. To gain a better understanding on the diversity and evolution of this group, we expanded prior phylogeographic work by incorporating populations from unsampled main Hawaiian Islands (Maui, Moloka'i, Lana'i, and Hawai'i, increasing the number of gene markers (four mitochondrial and two nuclear genes, and conducting Maximum likelihood and Bayesian phylogenetic analyses. Our study revealed new lineages and expanded the distribution range of several lineages. The phylogeographic patterns of Ligia in the study area are complex, with Hawai'i, O'ahu, and the Maui-Nui islands sharing major lineages, implying multiple inter-island historical dispersal events. In contrast, the oldest and most geographically distant of the major islands (Kaua'i shares no lineages with the other islands. Our results did not support the monophyly of all the supralittoral lineages (currently grouped into L. hawaiensis, or the monophyly of the terrestrial lineages (currently grouped into L. perkinsi, implying more than one evolutionary transition between coastal and inland forms. Geometric-morphometric analyses of three supralittoral clades revealed significant body shape differences among them

    2000-01-01

    The San Francisco Bay Area in California and its surroundings are shown in this radar image from the Shuttle Radar Topography Mission (SRTM). On this image, smooth areas, such as the bay, lakes, roads and airport runways appear dark, while areas with buildings and trees appear bright. Downtown San Francisco is at the center and the city of Oakland is at the right across the San Francisco Bay. Some city areas, such as the South of Market district in San Francisco, appear bright due to the alignment of streets and buildings with respect to the incoming radar beam. Three of the bridges spanning the Bay are seen in this image. The Bay Bridge is in the center and extends from the city of San Francisco to Yerba Buena and Treasure Islands, and from there to Oakland. The Golden Gate Bridge is to the left and extends from San Francisco to Sausalito. The Richmond-San Rafael Bridge is in the upper right and extends from San Rafael to Richmond. Angel Island is the large island east of the Golden Gate Bridge, and lies north of the much smaller Alcatraz Island. The Alameda Naval Air Station is seen just below the Bay Bridge at the center of the image. Two major faults bounding the San Francisco-Oakland urban areas are visible on this image. The San Andreas fault, on the San Francisco peninsula, is seen on the left side of the image. The fault trace is the straight feature filled with linear reservoirs, which appear dark. The Hayward fault is the straight feature on the right side of the image between the urban areas and the hillier terrain to the east.This radar image was acquired by just one of SRTM's two antennas and, consequently, does not show topographic data, but only the strength of the radar signal reflected from the ground. This signal, known as radar backscatter, provides insight into the nature of the surface, including its roughness, vegetation cover and urbanization. The overall faint striping pattern in the images is a data processing artifact due to the

    2015-02-01

    Full Text Available Recent advances in the use of GC coupled to MS have allowed a chemically guided isolation of uncommon and bioactive alkaloids. The present study was aimed to focus on the extraction and screening of alkaloids from Epipremnum aureum (Linden and Andre Bunting. It has been observed that the plant is very rich in alkaloids and the modified method employed for the extraction of alkaloid is efficient and selective, where the interference of other secondary metabolites is negligible. The identification of each compound was made through gas chromatography-mass spectrometry (GC-MS. A total of twenty six structurally different alkaloids were identified for the first time from this plant. E. aureum is highly rich in alkaloids and twenty six different alkaloids were characterized. The present study may help in the field of natural products’ chemistry and pharmaceuticals as well as drug discovery science and technology.

  6. A case for historic joint rupture of the San Andreas and San Jacinto faults

    Lozos, Julian C.

    2016-01-01

    The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data and historic observations for the ~M7.5 earthquake of 8 December 1812 are best explained by a rupture that begins on the San Jacinto fault and propagates onto the San Andreas fault. This precedent carries the implications that similar joint ruptures are possible in the future and that the San Jacinto fault plays a more significant role in seismic hazard in southern California than previously considered. My work also shows how physics-based modeling can be used for interpreting paleoseismic data sets and understanding prehistoric fault behavior. PMID:27034977

    2005-11-01

    Currently the mainstream technology of SAN is SAN storage virtualization and its implementation. The switch-based storage virtualization embeds the virtualizer in the core of the storage networking fabric in an "intelligent switch" rather than an appliance or a host. This paper describes the SV-FC SAN switch's hardware and software architecture. The main aid of design and implementation the switch is to give a new way to realize FC-SAN storage virtualization. Storage virtualization modules are embedded in the switches firmware. The switch can provide simple and friendly interfaces for users to configure and manage the FC SAN.

    Coral reefs are important because of their high biodiversity and their key role in the tropical marine biosphere. Furthermore, coral reefs are very valuable as a socioeconomic resource as they make important contributions to the gross domestic product of many countries. Thus, it is very important to monitor dynamic spatial distributions of coral reefs and related habitats dominated by coral rubble, dead coral, and bleached corals. Despite these natural and socio-economic advantages, many factors are threatening coral reefs. The study site was selected in Spermonde archipelago, South Sulawesi, Indonesia because this area is included in the Coral Triangle, recognized as the epicenter of coral diversity and a priority for conservation. Images of Landsat MSS, Landsat TM, Landsat ETM, Landsat ETM+, and Landsat 8 data were used to examine changes in the coral reefs of Suranti Island in the Spermonde Archipelago during forty one years from 1972 to 2013. The image processing includes gap fills, atmospheric corrections, geometric corrections, image composites, water column corrections, unsupervised classifications, and reclassifications. Fill Gap processing was done on Landsat ETM+ SLC-off. Subsequently, a multi-component change detection procedure was applied to define changes. Shallow water bottom types classification was divided into live coral, rubble and sand habitats, dead coral with algae, rubble, and sand. Preliminary results showed significant changes during the period 1972-2013 as well as changes in coral reefs, likely explained partly by destructive fishing practices.

  10. Recent cryptic extinction of squamate reptiles on Yoronjima Island of the Ryukyu Archipelago, Japan, inferred from garbage dump remains

    Yasuyuki Nakamura

    2013-07-01

    Full Text Available We report recent skeletal remains of squamate reptiles screened from an old garbage dump deposit found on Yoronjima Island, a small island of the Ryukyu Archipelago, in the subtropical northwestern Pacific. Identified remains include at least three species of terrestrial snakes, one sea snake, and seven species of lizards. Among these, the Ryukyu Short-legged Skink, Ateuchosaurus pellopleurus; Kuroiwa’s Leopard Gecko, Goniurosaurus kuroiwae; and one unidentified Gekko species constitute entirely new findings. For a further two snake species and one lizard species, the evidence presented here is the first specimen-based documentation that these species existed on this island, where they are now evidently absent. The present absence of these species on Yoronjima is mainly attributable to predation by the Japanese Weasel, Mustela itatsi, introduced in the mid-1950s. Our results demonstrate a prominent case of recent, sizable deterioration of insular herpetofaunal diversity, which has never been documented with certainty in the Ryukyu Archipelago, and suggest that human influence should be taken into account in biodiversity research in this area.

  11. Zonation and spatial distribution of littoral fish communities from the southwestern Finnish coast (Archipelago and Bothnian Sea, Northern Baltic Sea)

    Vahteri, Petri; O'Brien, Kevin; Vuorinen, Ilppo

    2009-03-01

    The aim of our study was to test whether the distribution of littoral fish assemblages would reflect both their immediate environment with reference to local underwater vegetation, including larger scale geographic archipelagial zonation. A total of 62 locations were sampled using beach seine and underwater video along the southwestern Finnish coastline in summer 2001. At all locations, water temperature, water transparency and benthic vegetation patterns (depth ranges of plant species or taxa) were recorded. Using correspondence analysis, our results showed a clear division of the Archipelago Sea into three separate zones based on littoral fish species assemblages. Overall, fish assemblages formed three distinct site groups, being dominated by pike and cyprinids, by percids and gobies, or by gasterosteids, and showed clear inner, middle and outer archipelago zones respectively, within the study area. Our results suggest that while vegetation in the study sites was diverse, it failed to express the zonation reflected by the littoral fish assemblages, which showed a definite zonation pattern which broadly reflected previous reports using both physical and biological parameters. We interpret our results to show that littoral vegetation is better in expressing small-scale differences between study sites, while littoral fish communities are more robust in detecting changes over a larger geographical scale.

  12. Long-term changes of species richness in a breeding bird community of a small Mediterranean archipelago

    Martínez-Abraín, A.

    2005-12-01

    Full Text Available We analyzed the pattern of species richness changes in a bird–breeding bird community on a small western Mediterranean archipelago (Columbretes Islands over a 40–year period (1964–2003. The aim of this study was to qualitatively account for the relative roles of local and regional factors in shaping the community. As expected, we found that regional factors (at the metapopulation spatial scale increased diversity whereas local factors (i.e. ecological probably prevented further increases in diversity. We found that the archipelago gained four new species (two seabirds and two falconids during the study period, whereas no extinctions were recorded. The community seems partially or completely closed to some groups of species (e.g. small–sized birds such as passerines and storm–petrels, probably owing to predatory exclusion by Eleonora falcons (Falco eleonorae. As newly arrived species have breeding calendars that do not fully overlap with those of resident species, competition for space in a rather saturated area is prevented. Preservation of rare species which increase gamma (regional diversity rather than alpha diversity with common species should be the main local conservation goal.

  13. Spatio-temporal variation in the diet of Cory's shearwater Calonectris diomedea in the Azores archipelago, northeast Atlantic

    Neves, Verónica; Nolf, Dirk; Clarke, Malcolm

    2012-12-01

    The diet of Cory's shearwater Calonectris diomedea in the Azores was studied in four islands of the archipelago over four breeding seasons, using stomach flushings from 959 birds. Fish were identified from flesh, otoliths and vertebrae and cephalopods from flesh and lower beaks. The frequency of occurrence of prey taxa, and the numerical frequency of fish and cephalopods, showed marked variations both spatially, across the breeding cycle and between years. Overall, cephalopods from 37 species representing 17 families and fish from 33 species representing 18 families were identified, representing over 70 prey species and trebling what was previously known. Histioteuthidae, Ommastrephidae and Cranchiidae were the only cephalopod families present every year and represented two thirds of the cephalopods' consumption by number. Blue jack mackerel Trachurus picturatus was the most abundant prey species present in 1998 and 2002 but was absent in 1999 and 2000, representing on average 57.2% of prey by number in the years it occurred. Apart from blue jack mackerel, most fish species were present in very low numbers with the exception of Cubiceps gracilis, Scomberesox saurus and Maurolicus muellerii. Diaphus adenomus, was recorded for the first time for the Azores archipelago.

    Full Text Available The regional impact of global climate change on the ocean circulation around the Galápagos Archipelago is studied using the Hybrid Coordinate Ocean Model (HYCOM configured for a four-level nested domain system. The modeling system is validated and calibrated using daily atmospheric forcing derived from the NCEP/NCAR reanalysis dataset from 1951 to 2007. The potential impact of future anthropogenic global warming (AGW in the Galápagos region is examined using the calibrated HYCOM with forcing derived from the IPCC-AR4 climate model. Results show that although the oceanic variability in the entire Galápagos region is significantly affected by global climate change, the degree of such effects is inhomogeneous across the region. The upwelling region to the west of the Isabella Island shows relatively slower warming trends compared to the eastern Galápagos region. Diagnostic analysis suggests that the variability in the western Galápagos upwelling region is affected mainly by equatorial undercurrent (EUC and Panama currents, while the central/east Galápagos is predominantly affected by both Peru and EUC currents. The inhomogeneous responses in different regions of the Galápagos Archipelago to future AGW can be explained by the incoherent changes of the various current systems in the Galápagos region as a result of global climate change.

  15. Extent of mangrove nursery habitats determines the geographic distribution of a coral reef fish in a South-Pacific archipelago.

    Christelle Paillon

    Full Text Available Understanding the drivers of species' geographic distribution has fundamental implications for the management of biodiversity. For coral reef fishes, mangroves have long been recognized as important nursery habitats sustaining biodiversity in the Western Atlantic but there is still debate about their role in the Indo-Pacific. Here, we combined LA-ICP-MS otolith microchemistry, underwater visual censuses (UVC and mangrove cartography to estimate the importance of mangroves for the Indo-Pacific coral reef fish Lutjanus fulviflamma in the archipelago of New Caledonia. Otolith elemental compositions allowed high discrimination of mangroves and reefs with 83.8% and 98.7% correct classification, respectively. Reefs were characterized by higher concentrations of Rb and Sr and mangroves by higher concentrations of Ba, Cr, Mn and Sn. All adult L. fulviflamma collected on reefs presented a mangrove signature during their juvenile stage with 85% inhabiting mangrove for their entire juvenile life (about 1 year. The analysis of 2942 UVC revealed that the species was absent from isolated islands of the New Caledonian archipelago where mangroves were absent. Furthermore, strong positive correlations existed between the abundance of L. fulviflamma and the area of mangrove (r = 0.84 for occurrence, 0.93 for density and 0.89 for biomass. These results indicate that mangrove forest is an obligatory juvenile habitat for L. fulviflamma in New Caledonia and emphasize the potential importance of mangroves for Indo-Pacific coral reef fishes.

  16. New data on Upper Carboniferous–Lower Permian deposits of Bol'shevik Island, Severnaya Zemlya Archipelago

    2015-05-01

    Full Text Available We present here a detailed study of the Upper Carboniferous–Lower Permian stratigraphy of Bol'shevik Island in the Severnaya Zemlya Archipelago, consisting of the analysis of sedimentary structures and lithostratigraphy, U/Pb detrital zircon dating and structural studies. The preserved sedimentary structures suggest that the studied strata were deposited in a relatively small meandering fluvial system. U/Pb dating of detrital zircons reveals that the Upper Carboniferous–Lower Permian sandstones contain a primary age population ranging from 450 to 570 millions of years, with a predominance of Early–Middle Ordovician zircons. This detrital zircon distribution indicates that the studied formations were derived locally from the erosion of Lower Ordovician deposits of Bol'shevik Island or elsewhere in the archipelago. Our structural studies suggest that Upper Carboniferous–Lower Permian deposits are deformed into a series of west–north-west verging open asymmetric folds, suggesting a west–north-west direction of tectonic transport and that deformation across the island is post-Early Permian in age.

    Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its conservation status has been impeded by taxonomic uncertainty, a paucity of field studies, and a lack of vouchered specimens and genetic samples available for study in biodiversity repositories. Consequently, conservation priorities are unclear. In this study we use mitochondrial and nuclear DNA to empirically infer geographic partitioning of genetic variation and to identify evolutionarily distinct lineages for conservation action. The distribution of Philippine tarsier genetic diversity is neither congruent with expectations based on biogeographical patterns documented in other Philippine vertebrates, nor does it agree with the most recent Philippine tarsier taxonomic arrangement. We identify three principal evolutionary lineages that do not correspond to the currently recognized subspecies, highlight the discovery of a novel cryptic and range-restricted subcenter of genetic variation in an unanticipated part of the archipelago, and identify additional geographically structured genetic variation that should be the focus of future studies and conservation action. Conservation of this flagship species necessitates establishment of protected areas and targeted conservation programs within the range of each genetically distinct variant of the Philippine tarsier.

  18. Accidental and ideal island cities: islanding processes and urban design in Belize City and the urban archipelagos of Europe

    Elizabeth Pigou-Dennis

    2014-11-01

    Full Text Available This paper explores processes of islanding, de-islanding, and re-islanding in the context of island cities. Although today popularly associated with rural, peripheral, and isolated landscapes, concepts of the ideal city coincided in Medieval and Renaissance Europe with emergent notions of the ideal island. Major European cities such as Amsterdam, Paris, and Copenhagen were established on densely urbanized small islands. In accordance with dominant political and military philosophies, they were subsequently developed through comprehensive urban design into vast yet coherent urban archipelagos. In contrast, the contemporary development of Belize City as an island city took place through piecemeal land reclamation, absent comprehensive urban design, resulting in a very different kind of urban archipelago. Neither the coherent European island cities nor Belize City are generally regarded as islands today, yet their histories of urban development evidence the impact of spatial attributes of islandness on urban form. Comprehensive urban design efforts are currently directed at land reclamation and waterfront revitalization in Belize City, aiming to restore Belize City’s island city status. We argue that cities can be islanded, de-islanded, and re-islanded in the minds of their inhabitants and that it is necessary to recognize the connection between ideal islands and ideal cities in order to understand the islanding process in full.

    Indonesian archipelago region is located in active tectonic setting and high seismicity zone. During the last decade, Indonesian was experienced with destructive major earthquakes causing damage and victims. The information of precise earthquake location parameters are very important in partular for earthquake early warning to the society and for advance seismic studies. In this study, we attempted to improve hypocenter location compiled by BMKG for time periods of April, 2009 up to June, 2014 for about 22,000 earthquake events around Indonesian region. For the firts time, we applied teleseismic double-difference relocation algorithm (teletomoDD) to improve hypocenter region in Indonesia region combining regional and teleseismic stations. Hypocenter relocation was performed utilizing local, regional, and teleseismic P-wave arrival time data. Our relocation result show that travel-time RMS errors were greatly reduced compared to the BMKG catalog. Seismicity at shallower depth (less than 50 km) shows significantly improvement especially in depth, and refined shallow geological structures, e.g. trench and major strike slip faults. Clustered seismicity is also detected beneath volcanic region, and probably related volcano activities and also major faults nearby. In the Sunda arc region, seismicity at shallower depth centered at two major distributions parallel to the trench strike direction, i.e. around fore-arc and in mainland that related to major fault, e.g. the Sumatran fault, and volcanic fronts. Below Central Java region, relocated hypocenter result showed double seismic zone pattern. A seismic gap is detected around the Sunda-Banda transition zone where transition between oceanic subduction to continental crust collision of Australian plate occurs. In Eastern Indonesia region, shallow earthquakes are observed related to major strike slip faults, e.g. Sorong and Palu-Koro fault, volcanism, and shallow part of subduction and collision zones.

  20. Paleomagnetism of Jurassic-Cretaceous basalts from the Franz Josef Land Archipelago: tectonic implications

    Abashev, Victor; Mikhaltsov, Nikolay; Vernikovsky, Valery

    2015-04-01

    New paleomagnetic data were obtained from a total of 158 oriented samples collected from the Jurassic magmatic complexes exposed on the Franz Joseph Land Archipelago (FJL). The field work was conducted during 2011 field season. Present study was focused on the tholeiitic basaltic lava flows that crop out on the Hooker Island. The samples were subjected to a detailed step-wise thermal demagnetization in temperatures up to 600 deg C or alternating field demagnetization with maximum filed up to 140 mT. Natural remanent magnetization (NRM) was measured with a 2G cryogenic magnetometer or a JR-6A spin-magnetometer housed in a magnetically shielded room at the Institute of Petroleum Geology and Geophysics, Siberian Branch of Russian Academy of Sciences. The main NRM carriers in the FJL samples are titanomagnetites with varying Ti-content. Magnetic remanence was unblocked in temperatures of 350-400 deg C. Some samples are characterized by unblocking temperatures of 560 deg C. The new paleomagnetic data were combined with those previously obtained from the early Cretaceous volcanics exposed on the FJL. A new mean paleomagnetic direction for the Jurassic rocks was calculated as D=78.3 deg, I=74.7 deg, a95=3.1 deg, k=194.3, N=13. A corresponding paleomagnetic pole is now located at Plat=62.1 deg; Plon=136.5 deg, A95=5.5 deg, K=63.6. New results suggest that the JFL occupied a significantly different position from that of the present day. However, in early Cretaceous the JFL was already located close to its present day position. We propose a rifting event between the North Barentz terrane (FJL and possibly Svalbard) and the counterpart of European tectonic domain. The rifting occurred during Early-Middle Jurassic. This event was accompanied by a significant shift of the FJL to the north-east for approximately 500 km. New results are in good agreement with a hypothesis that the FJL was passing over the Icelandic-Siberian hot spot during the Jurassic-Cretaceous time

  1. The First Paleomagnetic data from the Cambrian basalts of Henrietta Island (De Long Archipelago, Arctic Ocean)

    2015-12-01

    Henrietta Island in De Long archipelago (East-Siberian sea) still remains poorly studied geologically but last investigations show that its volcano-sedimentary sequences can help reconstruct tectonic evolution of East Russian Arctic in Early Paleozoic stage. The deposits lying on Precambrian basements are deformed to varying degrees and intruded by mafic dykes.The study was carried out on two basaltic lava flows whose 40Ar/39Ar age is 520.6±9.5 Ma. Previously the age of these basalts was assumed Cretaceous. According to available data the underlaying sediments contain zircons with Cambrian and Ordovician ages but all boundaries between these basalts and other strata are tectonic. So we suppose the age of basalts as Middle Cambrian but more precise geochronological data are required. All magnetic measurements were performed at the Laboratory of Geodynamics and Paleomagnetism of Institute of Petroleum Geology and Geophysics (Novosibirsk). Basalt samples has relatively high magnetic susceptibility values varying from 5x10-4 to 180x10-4SI units. NRM values range is from 3 to 170 mA/m. Petromagnetic parameters including also coercive characteristics point at the good potentially preserving primary magnetization. Stepwise thermal demagnetization permits to isolate characteristic components of magnetization and calculate mean directions in two lava flows: 1. Ds=294.3°, Is=29.1°, K=81.1, α95=5.1; 2. Ds=301.0°, Is=28.3°, K=34.4, α95=7.9). The mean paleomagnetic pole has coordinates: Plat=20.9°, Plong = 42.6°, dp/dm=14.3/7.9. Paleolatitude was defined as 15.3° but the question of the hemisphere for De Long Islands is open yet. In case of south hemisphere in Middle Cambrian according to available paleomagnetic data De Long islands could be placed close to Taimyr margin of Siberia and in case of northern hemisphere they may be located near south (in present-day coordinates) margin of Siberia. The work was supported by grant RFBR 14-05-31399 and Russian Research Fund

  3. Topoclimatic modeling of summer surface air temperature in the Canadian Arctic Archipelago

    Atkinson, David E.

    2000-06-01

    In the Canadian High Arctic general patterns of temperature are poorly resolved at the meso-scale. This project addressed this issue in three stages. In the first stage a data set of non-standard weather observations was assembled and quality controlled The data set possessed approximately 58000 observations, including dry-bulb temperature, wind, visibility and cloud cover, from the spring and summer seasons of the years 1974-1993. Up to 10% of the data were unusable due to erroneous station information. The second part of the project consisted of a principal components analysis (PCA) of daily temperature data in the Canadian Arctic Archipelago (CAA). The PCA (1)demonstrated how the timing and extent of synoptic events could be tracked, (2)identified the major regional controls of temperature in the CAA, and (3)showed that the non-standard data exhibited general coherency with regional patterns yet were able to reveal zones of coherency at the meso-scale in temperature patterns. In the third stage of the project a model to estimate surface air temperature at the meso-scale was constructed, It was based on a 1 km resolution digital elevation model of the CAA. The effects on temperature due to site elevation and coastal proximity were selected for parameterization. The change in temperature with elevation was implemented in the model using derived environmental lapse rates. Advection effects were handled using resultant winds combined with air temperature above the ocean. Lapse rates and resultant wind estimates were obtained from upper air ascents. Model results for 14-day runs were compared to observed data. Residuals (n = 385) possessed a mean absolute error of 1.5°C. The model was sensitive to steep surface inversions and to low- level warming. Sensitivity analyses were performed on the model to determine response to alterations in lapse rate calculation, sea surface temperature, and wind field generation. The model was most sensitive to lapse rate calculation

  4. Suboxic dolomite formation linked to the sedimentary Mn cycle, Archipelago Los Roques, Venezuela

    Petrash, D.; Lalonde, S.; Gonzalez, G.; Gingras, M.; Konhauser, K.

    2013-12-01

    The preferential formation of Ca-rich dolomite precursors in modern peritidal environments has been associated with the degradation of buried microbial mats, with complexation of Ca and Mg cations by extracellular polysaccharides, and alkalinity generation, mostly through bacterial sulfate reduction. However, it remains unclear why Ca-dolomite would not occur in suboxic sediments where bacterial Mn(IV) and/or Fe(III) reduction are important sources of alkalinity, and the role, if any, of Fe- and Mn-recycling in its diagenetic stabilization to more stoichiometric dolomite is unknown. In a shoaling-upward parasequence in the Archipelago Los Roques, Venezuela, an abundance of Ca-dolomite coincides with a relative decrease in bulk-sediment iron concentrations. These sediments were analyzed with multiple analytical tools, including EPMA, ICP-MS, synchrotron-based XRF, XRD, and spatially resolved XANES. Results demonstrate that the distribution of spheroidal aggregates of nanometer-scale Ca-rich dolomite rhombohedra is linked with interstitial elemental sulfur and manganese accumulations, with Mn occurring in several oxidation states (Fig. 1). Based on our observations at this novel dolomite-forming site, we suggest that in peritidal settings the burial of metal-reactive microbial mats act as a barrier capable of concentrating dissolved reactive species that promote greater sediment residence times in suboxic (manganic) zones, where the recycling of Mn not only plays an important role in the remineralization of organic matter, but also sustains elevated alkalinity and dissolved pore water sulfide concentrations. The last two effects have been previously suggested to promote Mg dehydration, the major kinetic barrier to dolomite nucleation. Figure 1. Normalized Mn K-edge merged spectra of a 5 x 5 μm analytical area bearing dolomite cements. A: The K-edge exhibits two main features at about 6554 and 6558 eV.

  6. A study of Neoclassical and Romantic features in the poetry of André Chénier, French poet of the 18th Century

    امینی امینی

    2013-01-01

    Full Text Available André Chénier (1762-1794 is the greatest and the best known French poet of the 18th century. He is famous especially for his courageous opposition to the power of the Terror in the early years of the French Revolution which caused finally his death by guillotine. The study of his poetical works can clarify the literary transition between neoclassicism and romanticism. This paper, by describing the poetry, the ideas and the time of Chénier, tries to demonstrate why it is impossible to limit his works merely to classicism. In fact he goes beyond the limits of classicism and toward romanticism, the literary school whose great followers call him their own precursor. Keywords: André Chénier, French poetry, neoclassicism, romanticism, literary schools.

    2012-09-01

    Full Text Available Green Jacks, Caranx caballus, are distributed along the Eastern Pacific coast. In Panama, C. caballus was heavily fished around Las Perlas Archipelago to sustain local markets until 2007, when the archipelago was declared a marine protected area. This first study in Panama, analyzed a sample of 4 990 individuals from Las Perlas, obtained monthly from June 2005 to June 2006, from landings at the central fish market. Average total length was 36.1±6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within ±10% of the optimal length but only six (15% were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE was best predicted by minimum annual values of the Multivariate ENSO/ LNSO Index (MEI (R²=0.54. Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of megaspawners in the population and guarantee the sustainability of this resource.El jurel verde o “cojinúa”, Caranx caballus, se distribuye a lo largo de la costa del Pacífico Oriental.

    2009-07-01

    The San Cristobal Galapagos wind power project was described. With its unique endemic flora and fauna, the Galapagos Islands were declared a world heritage site and marine reserve. The San Cristobal wind project was initiated in 1999 to reduce the environmental impacts of energy use on the island, and has been operational since 2007. Three 800 kW wind turbines have been installed in order to reduce 52 per cent of the island's diesel generation. The project's high penetration wind-diesel hybrid system included 300 kW diesel generators, a 13.2 kV utility distribution system, and six 300 kW wind turbines. The project is located outside of Galapagos Petrel flight paths and nesting areas. Turbines from a factory in Spain were used. The wind turbine foundation was constructed from concrete sand and stone mined on the island. Photographs of the installation process were included. tabs., figs.

  13. SANS Measurement of Hydrides in Uranium

    SANS scattering is shown to be an effective method for detecting the presence of hydrogen precipitates in uranium. High purity polycrystalline samples of depleted uranium were given several hydriding treatments which included extended exposures to hydrogen gas at two different pressures at 630 C as well as a furnace anneal at 850 C followed by slow cooling in the near absence hydrogen gas. All samples exhibited neutron scattering that was in proportion to the expected levels of hydrogen content. While the scattering signal was strong, the shape of the scattering curve indicated that the scattering objects were large sized objects. Only by use of a very high angular resolution SANS technique was it possible to make estimates of the major diameter of the scattering objects. This analysis permits an estimate of the volume fraction and means size of the hydride precipitates in uranium

    2014-06-01

    An updated summary of a future large astrometric catalogue is presented, based on the two most important astrometric projects carried out by the Real Instituto y Observatorio de la Armada de San Fernando (ROA). The goal is to make a catalogue of positions and proper motions based on ROA's Cart du Ciel (CdC) and the Astrographic Catalogue (AC) San Fernando zone plates, and the HAMC2 meridian circle catalogue. The CdC and AC plates are being reduced together to provide first-epoch positions while HAMC2 will provide second-epoch ones. New techniques have been applied, that range from using a commercial flatbed scanner to the proper reduction schemes to avoid systematics from it. Only thirty plates (out of 540) remain to be processed, due to scanning problems that are being solved.

    The instrument SANS-1 at the Geesthacht neutron facility GeNF was used for scattering experiments in 2000 at 196 of 200 days of reactor and cold source operation. The utilisation was shared between the in-house R and D program and user groups from different universities and research centers. These measurements were performed and analysed either by guest scientists or GKSS staff. The focus of the work in 2000 at the experiment SANS-1 was the structural investigation of hydrogen containing substances such as biological macromolecules (ribosomes, protein-RNA-complexes, protein solutions, glycolipids and membranes), molecules which are important in the fields of environmental research (refractoric organic substances) and technical chemistry (surfactants, micelles).

    The U.S. Geological Survey (USGS), at the request of the U.S. Fish and Wildlife Service, evaluated the water production capacity of an artesian well in the San Bernardino National Wildlife Refuge, Arizona. Water from the well initially flows into a pond containing three federally threatened or endangered fish species, and water from this pond feeds an adjacent pond/wetland containing an endangered plant species.

  18. Anisotropy of SANS in metallic glasses

    SANS in metallic glasses is anisotropic and depends on the ribbon's orientation. Pd-based melt spun and Ni-based electrochemically deposited glasses exhibit different anisotropies. Both glasses contain scattering centers of the order of 40nm wide in the ribbon plane. In the melt-spun alloy, the scatterers are very thin along the thickness perpendicular to the substrate. In the deposited alloy however, the defects are long along the thickness perpendicular to the electrode

    Salt management has been a challenge to westside farmerssince the rapid expansion of irrigated agriculture in the 1900 s. Thesoils in this area are naturally salt-affected having formed from marinesedimentary rocks rich in sea salts rendering the shallow groundwater,and drainage return flows discharging into the lower reaches of the SanJoaquin River, saline. Salinity problems are affected by the importedwater supply from Delta where the Sacramento and San Joaquin Riverscombine. Water quality objectives on salinity and boron have been inplace for decades to protect beneficial uses of the river. However it wasthe selenium-induced avian toxicity that occurred in the evaporationponds of Kesterson Reservoir (the terminal reservoir of a planned but notcompleted San Joaquin Basin Master Drain) that changed public attitudesabout agricultural drainage and initiated a steady stream ofenvironmental legislation directed at reducing non-point source pollutionof the River. Annual and monthly selenium load restrictions and salinityand boron Total Maximum Daily Loads (TMDLs) are the most recent of thesepolicy initiatives. Failure by both State and Federal water agencies toconstruct a Master Drain facility serving mostly west-side irrigatedagriculture has constrained these agencies to consider only In-Valleysolutions to ongoing drainage problems. For the Westlands subarea, whichhas no surface irrigation drainage outlet to the San Joaquin River,innovative drainage reuse systems such as the Integrated Farm DrainageManagement (IFDM) offer short- to medium-term solutions while morepermanent remedies to salt disposal are being investigated. Real-timesalinity management, which requires improved coordination of east-sidereservoir releases and west-side drainage, offers some relief toGrasslands Basin farmers and wetland managers - allowing greater salinityloading to the River than under a strict TMDL. However, currentregulation drives a policy that results in a moratorium on all

    Interaction between human activities, climate evolution and sea level can be summarised in a system where every element impacts the others. In the Kerkennah archipelago (Tunisia), recent observations have shown that the climate has become more arid, that the sea level is rising and that the society is modernizing at least since 1970. In our work we tried to understand the relations between the elements of the socio-ecosystem of Kerkennah to identify potential causes of the coastline movements and sabkhas extension (low and salty areas). Using photointerpretation (topographic map, Spot 5 image, aerial photographs) and remote sensing (2 landsat TM5 images), we detected and evaluated the movements of the coastline and of the sabkhas limits. Field data have also been added and all information has been used together in a GIS showing a significant retreat of the coastline (maximum of 41.2±6m in 47years) and an increase in the surface of sabkhas (+18%) between 1963 and 2010. The same dataset has been reanalysed at a much finer spatial scale to correlate observed changes to human pressure. This showed that coast erosion rates are more important where the coastline is partially artificialized or just after the end of a dam or a rockfill. Advances to the sea observed on some portions of the coast are always linked to human infrastructures. We conclude that the climatic change and the sea level rise increased the physical vulnerability of the archipelago and that the human installations near the coast amplify this vulnerability. Similarly, the extension of sabkha surfaces is global and most likely due to a natural perturbation of the seasonal cycle in the sabkhas by the sea level rise and by the stronger aridity in summer. However, discrepancies exist between individual areas and can be explained by the presence of active fault and/or by the evolution of agricultural practices. Indeed, frequent periods of drought and the political will for development of the Kerkennah
