    This work looks into the feasibility of implementing a scheme for the islanding of the Santa Cruz Thermic Plant ( Rio de janeiro State) with LIGHT`s (Electric power public utility) loads fed by the Santa Cruz-Jacarepagua trunk connection, considering presently-existing system problems relative to a significant frequency drop when a loss occurs of a large generation block and which causes the blockade scheme of the mentioned Plant to work, thus aggravating the frequency control still further. An analysis is made of such scheme implementation implications on the scheme for islanding a Santa Cruz 84 MW machine to provide supply to the auxiliary services of The Angra dos Reis nuclear plant presently existing in the system. 2 refs., 9 figs.

    Streamflow records obtained in the upper Santa Cruz River basin of southern Arizona, United States, and northern Sonora, Mexico, have been analyzed to aid in the appraisal of the surface-water resources of the area. Records are available for 15 sites, and the length of record ranges from 60 years for the gaging station on the Santa .Cruz River at Tucson to 6 years for Pantano Wash near Vail. The analysis provides information on flow duration, low-flow frequency magnitude, flood-volume frequency and magnitude, and storage requirements to maintain selected draft rates. Flood-peak information collected from the gaging stations has been projected on a regional basis from which estimates of flood magnitude and frequency may be made for any site in the basin. Most streams in the 3,503-square-mile basin are ephemeral. Ground water sustains low flows only at Santa Cruz River near Nogales, Sonoita Creek near Patagonia, and Pantano Wash near Vail. Elsewhere, flow occurs only in direct response to precipitation. The median number of days per year in which there is no flow ranges from 4 at Sonoita Creek near Patagonia to 335 at Rillito Creek near Tomson. The streamflow is extremely variable from year to year, and annual flows have a coefficient of variation close to or exceeding unity at most stations. Although the amount of flow in the basin is small most of the time, the area is subject to floods. Most floods result from high-intensity precipitation caused by thunderstorms during the period ,July to September. Occasionally, when snowfall at the lower altitudes is followed by rain, winter floods produce large volumes of flow.

    From Argentin lake, at west on Andean hills, to Puerto Santa Cruz on Atlantic coast, Santa Cruz river cross eastward Santa Cruz province over 250 km in Patagonia at southern Argentina. Present bed of the river has a meandering outline with first order meanders of great ratio bends and second order meanders of minor ratio bends. Principal wanderings are 45 to 55 km spaced from near Estancia La Julia or Rio Bote at west to Comandante Luis Piedrabuena at east. On river's bed middle sector these great curvatures are located at Estancia Condor Cliff and Estancia Rincon Grande. Regional and partial detailed studies allow to recognize structural control on river's bed sketch and valley s geomorphology that relates first order bends with reactivated principal faults. These faults fit well with parallel system of northwest strike of Austral Basin.On geological, geomorphologic and structural evidences recognized in Santa Cruz river, quaternary tectonic activity, related to Andean movements in southern Patagonian foreland, is postulated.

    This investigation aimed to document surgical capacity at public medical centers in a middle-income Latin American country using the Surgeons OverSeas (SOS) Personnel, Infrastructure, Procedures, Equipment, and Supplies (PIPES) survey tool. We applied the PIPES tool at six urban and 25 rural facilities in Santa Cruz, Bolivia. Outcome measures included the availability of items in five domains (Personnel, Infrastructure, Procedures, Equipment, and Supplies) and the PIPES index. PIPES indices were calculated by summing scores from each domain, dividing by the total number of survey items, and multiplying by 10. Thirty-one of the 32 public facilities that provide surgical care in Santa Cruz were assessed. Santa Cruz had at least 7.8 surgeons and 2.8 anesthesiologists per 100,000 population. However, these providers were unequally distributed, such that nine rural sites had no anesthesiologist. Few rural facilities had blood banking (4/25), anesthesia machines (11/25), postoperative care (11/25), or intensive care units (1/25). PIPES indices ranged from 5.7-13.2, and were significantly higher in urban (median 12.6) than rural (median 7.8) areas (P Bolivia's development status. Unfortunately, surgeons are limited in rural areas by deficits in anesthesia and perioperative services. These results are currently being used to target local quality improvement initiatives.

As pesquisas realizadas nas escolas municipais, estaduais e privadas na região de Santa Cruz do Sul permitem uma análise pontual das relações entre a educação e a imobilidade social, cujo resultado pode ser avaliado na dinâmica da visibilidade/invisibilidade identitária e processos de exclusão comunitário destes grupos, nomeadamente dos afrodescendentes.The objective of this article is to analyze the relations among education, ethnicity and social mobility in the region of German colonization in Rio Grande do Sul, and mainly in Santa Cruz do Sul, Brazil, a city with strong German identity speech. Taking into consideration that it is a city characterized by Germanism, what was observed in the researches accomplished until now, including the last six years, is that the region in question has a significant population of non-white people, though socially invisible and excluded from the identitary inclusion process of the region community. The researches that were carried out in the private and public – municipal and state – schools in the region of Santa Cruz do Sul permit sharp analysis of the relations between education and social immobility, which result can be evaluated in the identitary visibility/invisibility dynamic and processes of community exclusion of those groups, nominally of Afro-descendants.

    IntroductionIn 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the limit of California’s State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath sonar data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow subsurface geology.The Offshore of Santa Cruz map area is located in central California, on the Pacific Coast about 98 km south of San Francisco. The city of Santa Cruz (population, about 63,000), the largest incorporated city in the map area and the county seat of Santa Cruz County, lies on uplifted marine terraces between the shoreline and the northwest-trending Santa Cruz Mountains, part of California’s Coast Ranges. All of California’s State Waters in the map area is part of the Monterey Bay National Marine Sanctuary.The map area is cut by an offshore section of the San Gregorio Fault Zone, and it lies about 20 kilometers southwest of the San Andreas Fault Zone. Regional folding and uplift along the coast has been attributed to a westward bend in the San Andreas Fault Zone and to right-lateral movement along the San Gregorio Fault Zone. Most of the coastal zone is characterized by low, rocky cliffs and sparse, small pocket beaches backed by low, terraced hills. Point Santa Cruz, which forms the north edge of Monterey Bay, provides protection for the beaches in the easternmost part of the map area by sheltering them from the predominantly northwesterly waves.The shelf in the map area is underlain by variable amounts (0 to 25 m) of

    The USA and Mexico have initiated comprehensive assessment of 4 of the 18 aquifers underlying their 3000 km border. Binational management of groundwater is not currently proposed. University and agency researchers plus USA and Mexican federal, state, and local agency staff have collaboratively identified key challenges facing the Santa Cruz River Valley Aquifer located between the states of Arizona and Sonora. The aquifer is subject to recharge variability, which is compounded by climate change, and is experiencing growing urban demand for groundwater. In this paper, we briefly review past, current, and projected pressures on Santa Cruz groundwater. We undertake first-order approximation of the relative magnitude of climate change and human demand drivers on the Santa Cruz water balance. Global circulation model output for emissions scenarios A1B, B1, and A2 present mixed trends, with annual precipitation projected to vary by ±20% over the 21st century. Results of our analysis indicate that urban water use will experience greater percentage change than climate-induced recharge (which remains the largest single component of the water balance). In the Mexican portion of the Santa Cruz, up to half of future total water demand will need to be met from non-aquifer sources. In the absence of water importation and with agricultural water use and rights increasingly appropriated for urban demand, wastewater is increasingly seen as a resource to meet urban demand. We consider decision making on both sides of the border and conclude by identifying short- and longer-term opportunities for further binational collaboration on transboundary aquifer assessment.

    Marine terraces in the central coast of California provide an opportunity to study a soil chronosequence in which similar materials (beach deposits) have been weathered under similar slope, climatic, and vegetation conditions during the Quaternary. The terraces between Santa Cruz and Año Nuevo, California, have been studied for decades and are thought to be one of the best example of marine terraces in California {Lawson (1893), Wilson (1907); Branner and others (1909), Rode (1930) Page and Holmes (1945), Alexander (1953), Bradley (1956, 1957, 1958, and 1965), Bradley and Addicott (1968), Clark (1966 and 1970), Jahns and Hamilton (1971), Lajoie and others (1972), Bradley and Griggs (1976).

    2002-01-01

    The marine terraces in and around Santa Cruz, California, represent a set of well-preserved terraces formed as a product of geology, sea level, and climate. A marine terrace begins as a wave cut platform. Eustatic sea level changes, seacliff erosion, and tectonic uplift work together to generate marine terraces. "When a wave-cut platform is raised (due to tectonic activity) above sea level and cliffed by wave action it becomes a marine terrace" (Bradley, 1957, p. 424). During glacial periods, eustatic sea level is estimated to have dropped by 150 meters (Fairbanks, 1989). Cliff retreat measured from aerial photographs between 1930 and 1980 vary from 0.0 to 0.2 m yr–1 (Best and Griggs, 1991). Estimates of uplift rates along the Santa Cruz coastline vary from 0.10 to 0.48 m kyr–1 (Bradley and Griggs, 1976; Weber and others, 1999). Uplift mechanisms include coseismic uplift associated both with a reverse component of slip on the steeply SW dipping Loma Prieta fault in the restraining bend of the San Andreas Fault and a small component of reverse slip on the steeply SE dipping San Gregorio fault (Anderson and Menking 1994). Previous work studying physical properties on these terraces include Pinney and others (in press) and Aniku (1986) and Bowman and Estrada (1980). Sedimentary deposits of the marine terraces are a mixture of terrestrial and marine sediments but generally consist of a sheet of marine deposits overlying the old platform and a wedge of nonmarine deposits banked against the old sea cliff (Bradley, 1957). Bedrock underlying the terraces in the Santa Cruz area is generally either Santa Margarita Sandstone or Santa Cruz Mudstone. The Santa Margarita Sandstone represents an upper Miocene, transgressive, tidally dominated marine-shelf deposit with crossbedded sets of sand and gravel and horizontally stratified and bioturbated invertebrate-fossils beds (Phillips, 1990). The siliceous Santa Cruz Mudstone, of late Miocene age, conformably overlies the Santa

    The distribution, chemistry, and morphology of Fe nodules were studied in a marine terrace soil chronosequence northwest of Santa Cruz, California. The Fe nodules are found at depths hyphae throughout the nodules, including organic structures incorporating fine-grained Fe oxides. The fine-grained nature of the Fe oxides was substantiated by M??ssbauer spectroscopy. Our microscopic observations led to the hypothesis that the nodules in the Santa Cruz terrace soils are precipitated by fungi, perhaps as a strategy to sequester primary mineral grains for nutrient extraction. The fungal structures are fixed by the seasonal wetting and dry cycles and rounded through bioturbation. The organic structures are compacted by the degradation of fungal C with time. ??

    We report the results of an investigation of a small outbreak of hantavirus pulmonary syndrome in 2002 in the Department of Santa Cruz, Bolivia, where the disease had not previously been reported. Two cases were initially reported. The first case was a physician infected with Laguna Negra virus during a weekend visit to his ranch. Four other persons living on the ranch were IgM antibody-positive, two of whom were symptomatic for mild hantavirus pulmonary syndrome. The second case was a migrant sugarcane worker. Although no sample remained to determine the specific infecting hantavirus, a virus 90% homologous with Río Mamoré virus was previously found in small-eared pygmy rice rats (Oligoryzomys microtis) trapped in the area. An antibody prevalence study conducted in the region as part of the outbreak investigation showed 45 (9.1%) of 494 persons to be IgG positive, illustrating that hantavirus infection is common in Santa Cruz Department. Precipitation in the months preceding the outbreak was particularly heavy in comparison to other years, suggesting a possible climatic or ecological influence on rodent populations and risk of hantavirus transmission to humans. Hantavirus infection appears to be common in the Santa Cruz Department, but more comprehensive surveillance and field studies are needed to fully understand the epidemiology and risk to humans.

  4. Multi-gauge Calibration for modeling the Semi-Arid Santa Cruz Watershed in Arizona-Mexico Border Area Using SWAT

    2012-01-01

    In most watershed-modeling studies, flow is calibrated at one monitoring site, usually at the watershed outlet. Like many arid and semi-arid watersheds, the main reach of the Santa Cruz watershed, located on the Arizona-Mexico border, is discontinuous for most of the year except during large flood events, and therefore the flow characteristics at the outlet do not represent the entire watershed. Calibration is required at multiple locations along the Santa Cruz River to improve model reliability. The objective of this study was to best portray surface water flow in this semiarid watershed and evaluate the effect of multi-gage calibration on flow predictions. In this study, the Soil and Water Assessment Tool (SWAT) was calibrated at seven monitoring stations, which improved model performance and increased the reliability of flow, in the Santa Cruz watershed. The most sensitive parameters to affect flow were found to be curve number (CN2), soil evaporation and compensation coefficient (ESCO), threshold water depth in shallow aquifer for return flow to occur (GWQMN), base flow alpha factor (Alpha_Bf), and effective hydraulic conductivity of the soil layer (Ch_K2). In comparison, when the model was established with a single calibration at the watershed outlet, flow predictions at other monitoring gages were inaccurate. This study emphasizes the importance of multi-gage calibration to develop a reliable watershed model in arid and semiarid environments. The developed model, with further calibration of water quality parameters will be an integral part of the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM), an online decision support tool, to assess the impacts of climate change and urban growth in the Santa Cruz watershed.

    1990-07-27

    The late Quaternary marine terraces near Santa Cruz, California, reflect uplift associated with the nearby restraining bend on the San Andreas fault. Excellent correspondence of the coseismic vertical displacement field caused by the 17 October 1989 magnitude 7.1 Loma Prieta earthquake and the present elevations of these terraces allows calculation of maximum long-term uplift rates 1 to 2 kilometers west of the San Andreas fault of 0.8 millimeters per year. Over several million years, this uplift, in concert with the right lateral translation of the resulting topography, and with continual attack by geomorphic processes, can account for the general topography of the northern Santa Cruz Mountains.

    The upper Santa Cruz Basin is an important groundwater basin containing the regional aquifer for the city of Nogales, Arizona. This report provides data and interpretations of data aimed at better understanding the bedrock morphology and structure of the upper Santa Cruz Basin study area which encompasses the Rio Rico and Nogales 1:24,000-scale U.S. Geological Survey quadrangles. Data used in this report include the Arizona Aeromagnetic and Gravity Maps and Data referred to here as the 1996 Patagonia Aeromagnetic survey, Bouguer gravity anomaly data, and conductivity-depth transforms (CDTs) from the 1998 Santa Cruz transient electromagnetic survey (whose data are included in appendixes 1 and 2 of this report).Analyses based on magnetic gradients worked well to identify the range-front faults along the Mt. Benedict horst block, the location of possibly fault-controlled canyons to the west of Mt. Benedict, the edges of buried lava flows, and numerous other concealed faults and contacts. Applying the 1996 Patagonia aeromagnetic survey data using the horizontal gradient method produced results that were most closely correlated with the observed geology.The 1996 Patagonia aeromagnetic survey was used to estimate depth to bedrock in the upper Santa Cruz Basin study area. Three different depth estimation methods were applied to the data: Euler deconvolution, horizontal gradient magnitude, and analytic signal. The final depth to bedrock map was produced by choosing the maximum depth from each of the three methods at a given location and combining all maximum depths. In locations of rocks with a known reversed natural remanent magnetic field, gravity based depth estimates from Gettings and Houser (1997) were used.The depth to bedrock map was supported by modeling aeromagnetic anomaly data along six profiles. These cross sectional models demonstrated that by using the depth to bedrock map generated in this study, known and concealed faults, measured and estimated magnetic

    Current legislation transferred public tertiary hospitals in Bolivia from the Municipalities to the Regional Level. However, the Regional Governments are experiencing technical and financial constraints to reform infrastructure, modernize equipment and introduce reforms to allow better governance, management and sustainability of these hospitals. This articles summarizes the recent experience of the Government of Santa Cruz de la Sierra in Bolivia where five tertiary hospitals and blood bank (most of them in precarious working conditions) has been transferred in 2012 from the Municipal Government of Santa Cruz (the capital) to the Regional Government of Santa Cruz. To face the challenges, the Regional Government of Santa Cruz implement several improvements, such as contract new clinical and administrative personal, increases hospital budgetary autonomy, outsource hospitals' auxiliary services, take measures to eliminate waiting lists and make several new investments to modernize and equip the hospitals. The World Bank was contracted to evaluated the future financial sustainability of these investments and to advice the Government to propose changes to increase the hospitals' management performance. The article describes the remaining challenges in these hospitals and the proposals from the World Bank Study. In the area of quality of care, the main challenge is to improve client satisfaction and continuous outcomes monitoring and evaluation according quality standards. In the area of financing, the challenge is how to assure the sustainability of these hospitals with the current level of health financing and the insufficient financial transfers from the National Government. In the area of Governance, reforms to streamline and simplify internal processes need to be introduced in order to establish mechanisms to increase transparency and accountability, allowing the hospital to have a good administration and adequate participation of the main actors in the guidance of

    Full Text Available The objective of this work was to identify and interpret the entomologic perception of students and teachers living in the Santa Cruz do Xingu, Médio Araguaia region. Semistructured interviews were carried out in December 2006 with students and teachers of the basic and intermediate levels, as well as in Youth and Adult Education, in the municipality of Santa Cruz do Xingu, Mato Grosso. Of the living beings perceived as “insects” by all the interviewees, 82.75% belonged to the Insecta Class, but the rest belonged either to the Fungi Kingdom or to Classes of Animalia (Amphibia, Arachnida, Chilopoda, Diplopoda, Gastropoda, Mammalia and Reptilia. The “insects” were defined by the interviewees as small bugs, which were disgusting and dangerous. When in contact with the “insects”, 76% of the interviewees admitted that they killed them, and the greatest reason given for this was the psychological damage caused by the presence of these animals (65%. To 78% of those interviewed, the “insects” were beings without positive importance. Due to the scarce knowledge about their positive aspects, the perception of the “insects” by the students and teachers living in the Santa Cruz do Xingu region is mainly related to their belief in the negative qualities of these animals, causing aggressive reactions against them as soon as they are perceived in the environment.

    The consumption of lacteal desserts in the province of Santa Cruz de Tenerife is notably high. However, there are no legal standards in Spain regarding microbiological quality. For this reason, we have decided that it would be of interest to carry out a health-sanitary study of these products, with the aim of discovering their microbial content. 330 samples of lacteal desserts on sale in the province of Santa Cruz de Tenerife have undergone analysis. They have been divided into three groups: cream caramel (egg and vanilla) (80), mousse (60) and the third group, known as "other desserts", which includes custard and the rest of lacteal desserts not included in the previous groupings (190). Neither E. coli, Salmonella spp., Shigella spp., nor Staphylococcus aureus have been detected in any of the samples analysed. In spite of the fact that the results obtained do not reflect high microbiological contamination, we consider it necessary to lay down legal standards, with reference values, for these lacteal products, which will guarantee good microbiological quality.

    On February 6, 2013 at 01:12:27 UTC (local time: UTC+11), a magnitude Mw 8.0 earthquake occurred 70 km to the west of Ndendo Island (Santa Cruz Island) in the Solomon Islands. The under-thrusting earthquake near a 90° bend, where the Australian plate subducts beneath the Pacific plate generated a locally focused tsunami in the Coral Sea and the South Pacific Ocean. The tsunami claimed the lives of 10 people and injured 15, destroyed 588 houses and partially damaged 478 houses, affecting 4,509 people in 1,066 households corresponding to an estimated 37% of the population of Santa Cruz Island. A multi-disciplinary international tsunami survey team (ITST) was deployed within days of the event to document flow depths, runup heights, inundation distances, sediment and coral boulder depositions, land level changes, damage patterns at various scales, performance of the man-made infrastructure and impact on the natural environment. The 19 to 23 February 2013 ITST covered 30 locations on 4 Islands: Ndendo (Santa Cruz), Tomotu Noi (Lord Howe), Nea Tomotu (Trevanion, Malo) and Tinakula. The reconnaissance completely circling Ndendo and Tinakula logged 240 km by small boat and additionally covered 20 km of Ndendo's hard hit western coastline by vehicle. The collected survey data includes more than 80 tsunami runup and flow depth measurements. The tsunami impact peaked at Manoputi on Ndendo's densely populated west coast with maximum tsunami height exceeding 11 m and local flow depths above ground exceeding 7 m. A fast tide-like positive amplitude of 1 m was recorded at Lata wharf inside Graciosa Bay on Ndendo Island and misleadingly reported in the media as representative tsunami height. The stark contrast between the field observations on exposed coastlines and the Lata tide gauge recording highlights the importance of rapid tsunami reconnaissance surveys. Inundation distance and damage more than 500 m inland were recorded at Lata airport on Ndendo Island. Landslides were

    In the borderland region of the desert southwest, human health and the ecosystems upon which humans rely largely depend on the quality, quantity, and distribution of water resources. In the Santa Cruz River Watershed (SCW), located in the Arizona and Sonora, Mexico border region, surface water is scarce and unreliable, and, during much of the year, is composed of effluent from the local wastewater treatment plant. This makes groundwater the preferred and, consequently, primary source for industrial, agricultural, and domestic use. USGS scientists are using an integrative approach, incorporating the expertise of the Geography, Water, Biology, and Geology disciplines to identify risks to water resources in the SCW, and the potential for impacts to riparian ecosystems and ultimately, human health. This includes tracking organic and inorganic contaminants and their effects from sources to sinks in sediment, water, plants, and animals. Existing ground- and surface-water models will be used and modified to assess contaminant and sediment transport. Water quality, sediment, aquatic macro invertebrates, aquatic plants (macrophytes), algae, riparian grasses, fish, and birds will be sampled at five locations along the Santa Cruz River. Field sampling data will be obtained at sites that coincide with historical sampling programs. Site locations include (i.) the Santa Cruz River headwaters (which should be unaffected by downstream contaminant sources), (ii.) a tributary routed through an abandoned mining district, (iii.) a binational tributary that flows though highly urbanized areas, (iv.) effluent from the local wastewater treatment plant, and (v.) the downstream confluence of the first four sources. The Soil and Water Assessment Tool (SWAT) model will be used in combination with field data to identify key sources of contaminants, contributing areas, and transport modes to track their movement to surface waters. These data will be used together to test relationships between

    2012-07-01

    To determine the annual periodicity of growth rings in seven tree species from a tropical moist forest in Santa Cruz, Bolivia, a fire scar was used as a marker point to verify the annual nature of tree rings. The number of tree rings formed between the 1995 fire scar and the collection of the cross sections in 2002 was visually identified. The seven species showed annual growth rings. In most cases, boundaries between rings were marked by the presence of marginal parenchyma and wall-thick ed fibers formed at the end of the growing season. Growth lenses and false rings were recorded in some species. Tree rings can be carefully used in Santa Cruz forests to determine rates of growth. This information is crucial for defining forest management practices in tropical regions. (Author) 21 refs.

    Full Text Available The Equality Revolution in Santa Cruz (1876-1877, also known as the equality movement, was a conflict between the pairing of the common urban class and local elites who defended a development formula that championed a modern age that balanced the social values of the traditional and patriarchal society, and other local elites who benefited from the boom of free-market capitalism. The political actions of the egalitarians was influenced by the ideology of romantic socialism in its different stages and combined legal formulas with pressure from peasant militia and civil uprisings. The disruption between the project defending a selfmanaged local way of life and local/state modernization priorities led to a state of repression rarely seen in XIX century Santa Cruz society.La Revolución de Igualdad en Santa Cruz (1876-1877 o movimiento igualitario fue un conflicto entre el binomio formado por las capas plebeyas urbanas y las elites locales, defensoras de la fórmula del desarrollo que abogaba por una modernidad en equilibrio con los valores sociales de la sociedad patriarcal y tradicional, y otras elites locales, beneficiarias del auge del capitalismo de libre cambio. La actuación política de los igualitarios estuvo influenciada por las ideas del socialismo romántico en todas sus etapas y combinó formas legales con presión armada montonera y sublevación popular. El desajuste entre este proyecto de defensa de un autogestionado modo de vida local y las prioridades locales/estatales de modernización provocó una represión del mismo pocas veces vista en la sociedad cruceña en el siglo XIX.

  10. Development of a high-resolution binational vegetation map of the Santa Cruz River riparian corridor and surrounding watershed, southern Arizona and northern Sonora, Mexico

    Science.gov (United States)

    Wallace, Cynthia S.A.; Villarreal, Miguel L.; Norman, Laura M.

    2011-01-01

    This report summarizes the development of a binational vegetation map developed for the Santa Cruz Watershed, which straddles the southern border of Arizona and the northern border of Sonora, Mexico. The map was created as an environmental input to the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM) that is being created by the U.S. Geological Survey for the watershed. The SCWEPM is a map-based multicriteria evaluation tool that allows stakeholders to explore tradeoffs between valued ecosystem services at multiple scales within a participatory decision-making process. Maps related to vegetation type and are needed for use in modeling wildlife habitat and other ecosystem services. Although detailed vegetation maps existed for the U.S. side of the border, there was a lack of consistent data for the Santa Cruz Watershed in Mexico. We produced a binational vegetation classification of the Santa Cruz River riparian habitat and watershed vegetation based on NatureServe Terrestrial Ecological Systems (TES) units using Classification And Regression Tree (CART) modeling. Environmental layers used as predictor data were derived from a seasonal set of Landsat Thematic Mapper (TM) images (spring, summer, and fall) and from a 30-meter digital-elevation-model (DEM) grid. Because both sources of environmental data are seamless across the international border, they are particularly suited to this binational modeling effort. Training data were compiled from existing field data for the riparian corridor and data collected by the NM-GAP (New Mexico Gap Analysis Project) team for the original Southwest Regional Gap Analysis Project (SWReGAP) modeling effort. Additional training data were collected from core areas of the SWReGAP classification itself, allowing the extrapolation of the SWReGAP mapping into the Mexican portion of the watershed without collecting additional training data.

    1980-01-01

    North-central Santa Cruz County is underlain mainly by folded sedimentary rocks of Tertiary and Cretaceous age that have been highly fractured by movements in the San Andreas fault system. Ground water is stored in fractures within shale and mudstone formations and in intergranular pore spaces within fine- to very fine-grained sandstone and siltstone formations. Fewer than 10% of the wells yield more than 15 gallons of water per minute. The water in most wells is moderately hard to very hard, is generally of a sodium bicarbonate or calcium bicarbonate type, and commonly has excessive concentrations of iron or manganese. Of the many geologic units in the study area, only the Purisima Formation of Pliocene age has the potential to sustain well yields greater than 100 gallons per minute. (USGS)

    Santa Cruz Island is the largest of the northern Channel Islands located off the coast of California. It is owned and managed as a conservation reserve by The Nature Conservancy and the Channel Islands National Park. The island is home to nine plant taxa listed in 1997 as threatened or endangered under the federal Endangered Species Act, because of declines related to nearly 150 years of ranching on the island. Feral livestock were removed from the island as a major conservation step, which was part of a program completed in early 2007 with the eradication of pigs and turkeys. For the first time in more than a century, the rare plants of Santa Cruz Island have a chance to recover in the wild. This study provides survey information and living plant materials needed for recovery management of the listed taxa. We developed a database containing information about historical collections of the nine taxa and used it to plan a survey strategy. Our objectives were to relocate as many of the previously known populations as possible, with emphasis on documenting sites not visited in several decades, sites that were poorly documented in the historical record, and sites spanning the range of environmental conditions inhabited by the taxa. From 2003 through 2006, we searched for and found 39 populations of the taxa, indicating that nearly 80 percent of the populations known earlier in the 1900s still existed. Most populations are small and isolated, occupying native-dominated habitat patches in a highly fragmented and invaded landscape; they are still at risk of declining through population losses. Most are not expanding beyond the edges of their habitat patches. However, most taxa appeared to have good seed production and a range of size classes in populations, indicating a good capacity for plant recruitment and population growth in these restricted sites. For these taxa, seed collection and outplanting might be a good strategy to increase numbers of populations for species

    Full Text Available Introducción: el embarazo en la adolescencia es una de las preocupaciones médicas más importantes derivadas de la conducta sexual de las jóvenes. Objetivo: identificar los factores de riesgo que influyen en el embarazo en la adolescencia en el municipio Santa Cruz del Norte. Métodos: se realizó un estudio de casos y controles sobre los factores predisponentes del embarazo en adolescentes de Santa Cruz del Norte, del año 2002 al 2011. El universo fue de 336 pacientes, escogiéndose una muestra de 252 al azar que conformó el grupo estudio, se dispuso de un grupo control de 252 pacientes primíparas no adolescentes. Los datos se recolectaron mediante encuesta y para el análisis estadístico se empleó la media, desviación estándar, porcentaje, Chi Cuadrado y Odds Ratio. Resultados: las adolescentes fueron mayormente amas de casa, la edad de inicio de las relaciones sexuales fue más precoz en el grupo estudio; la mayoría de las adolescentes no utilizaban métodos anticonceptivos; la crianza de éstas no fue realizada por ambos padres y se desarrollaron en un medio familiar disfuncional mayoritariamente. Conclusiones: existen múltiples factores de riesgo para el embarazo en adolescentes susceptibles de ser modificados desde la atención primaria de salud.

Entrevistas semi-estruturadas foram realizadas em dezembro de 2006 com alunos e professores dos ensinos fundamental, médio e Educação de Jovens e Adultos em dezembro de 2006, no Município de Santa Cruz do Xingu, Mato Grosso. Dos seres vivos percebidos como “insetos” por todos os entrevistados, 82,75% pertenceram à Classe Insecta, as demais citações foram pertencentes ao Reino Fungi e a outras Classes do Reino Animalia (Amphibia, Arachnida, Chilopoda, Diplopoda, Gastropoda, Mammalia e Reptilia. Os “insetos” foram definidos, como bichos pequenos, nojentos ou perigosos. Em contato com os “insetos”, 76% dos entrevistados admitiram matá-los e a maior razão para tal reação foi o dano psicológico causado pela presença destes animais (65%. Para 78% dos entrevistados, os “insetos” foram seres sem importância positiva. Devido ao pouco conhecimento sobre os seus aspectos positivos, a percepção dos “insetos” por alunos e professores residentes da região de Santa Cruz do Xingu está relacionada, principalmente, à atribuição de qualidades negativas a estes animais, provocando reações de agressividade contra os “insetos” assim que percebidos no ambiente.

De los 11 ítems presa identificados, los más consumidos por los adultos (tanto machos como hembras fueron los coleópteros. En los machos la segunda categoría presa mas importante en la contribución a la dieta fueron los ácaros, mientras que en las hembras las hormigas y las larvas de insectos siguieron en importancia al consumo de coleópteros. En los especímenes juveniles, los ácaros fueron las presas más consumidas, quedando los coleópteros en segundo lugar en importancia relativa. Se demuestra la existencia de una correlación positiva significativa entre el volumen de las presas y el tamaño del depredador. Se aportan datos referentes a la fecundidad de B. variegatus y se comprueba la ausencia de correlación entre el tamaño de las hembras grávidas y el número de óvulos maduros. The diet of a population of Bufo variegatus from the region of Lago del Desierto, Santa Cruz province, Argentina, is described. Of the 11 prey items identified, Coleoptera was the most consumed prey both for males and females. In males, the second most important prey was Acarii, while in females they were the ants and insect larvae. Acarii was the most consumed prey for juveniles, followed by Coleoptera. A significant positive correlation was found between prey volume and predator body size. Fecundity information for B. variegwus is given, and a lack of correlation between snout-vent length of mature females and ovarian egg complement is demonstrated.

El Chaltén y El Calafate son los asentamientos que desarrollan el turismo como base de su economía. El incremento de la actividad se debe a los cambios en el sistema productivo provincial en las últimas décadas, netamente ganadero en El Calafate a principios y mediados del siglo XX. Asimismo, las razones geopolíticas que dieron origen a El Chaltén, hoy han pasado a ser parte de su historia, ya que el turismo es la principal actividad que desarrolla el asentamiento. Esta actividad en la provincia se ha incrementado a partir de la década del 1990 impulsada por los Estados nacional, provincial y municipal que llevan adelante políticas de promoción en el sector. Por otra parte, en estos asentamientos, el auge turístico trae aparejado consecuencias sociales y ambientales dado el crecimiento acelerado de los mismos en cuanto a la población que se radica, la falta de infraestructura básica y equipamiento son los principales sin dejar de mencionar la especulación inmobiliaria.

    2010-01-01

    In 2004 the U.S. Geological Survey (USGS) launched the Border Environmental Health Initiative (BEHI), a major project encompassing the entire U.S.-Mexico border region. In 2009, a study of the Santa Cruz River Watershed (SCW), located in the border region of Arizona and Sonora, Mexico, was initiated as part of the BEHI. In this borderland region of the desert Southwest, human health and the ecosystems on which humans rely depend critically on limited water resources. Surface water is scarce during much of the year, and groundwater is the primary source for industrial, agricultural, and domestic use. In order to identify risks to water resources in the SCW, and the potential consequences to riparian ecosystems and ultimately human health, the USGS is using an interdisciplinary and integrative approach that incorporates the expertise of geographers, hydrologists, biologists, and geologists to track organic and inorganic contaminants and their effects from sources to sinks in sediment, water, plants, and animals. Existing groundwater and surface-water models are being used and modified to assess contaminant and sediment transport.

    Background We conducted a study of congenital Trypanosoma cruzi infection in Santa Cruz, Bolivia. Our objective was to apply new tools to identify weak points in current screening algorithms, and find ways to improve them. Methods Women presenting for delivery were screened by rapid and conventional serological tests. For infants of infected mothers, blood specimens obtained on days 0, 7, 21, 30, 90, 180, and 270 were concentrated and examined microscopically; serological tests were performed for the day 90, 180, and 270 specimens. Maternal and infant specimens, including umbilical tissue, were tested by polymerase chain reaction (PCR) targeting the kinetoplast minicircle and by quantitative PCR. Results Of 530 women, 154 (29%) were seropositive. Ten infants had congenital T. cruzi infection. Only 4 infants had positive results of microscopy evaluation in the first month, and none had positive cord blood microscopy results. PCR results were positive for 6 (67%) of 9 cord blood and 7 (87.5%) of 8 umbilical tissue specimens. PCR-positive women were more likely to transmit T. cruzi than were seropositive women with negative PCR results (P < .05). Parasite loads determined by quantitative PCR were higher for mothers of infected infants than for seropositive mothers of uninfected infants (P < .01). Despite intensive efforts, only 58% of at-risk infants had a month 9 specimen collected. Conclusions On the basis of the low sensitivity of microscopy in cord blood and high rate of loss to follow-up, we estimate that current screening programs miss one-half of all infected infants. Molecular techniques may improve early detection. PMID:19877966

    In order to explore the reasons for the apparent discrepancy between laboratory and field weathering rates and to determine the extent to which weathering rates are controlled by the approach to thermodynamic equilibrium, secondary mineral precipitation, and flow rates, a multicomponent reactive transport model (CrunchFlow) was used to interpret soil profile development and mineral precipitation and dissolution rates at the 226 ka Marine Terrace Chronosequence near Santa Cruz, CA.

    Acute respiratory infections represent a serious public health issue worldwide but virological aetiologies of Influenza Like Illnesses (ILIs) remain largely unknown in developing countries. This study represents the first attempt to characterise viral aetiologies of ILIs in Bolivia. It was performed in Santa Cruz city from January 2010 to September 2012, based on 564 naso-pharyngeal swabs collected in a National Reference Laboratory and real-time PCR techniques, viral cultures and phylogenetic analyses. 50.2% of samples were positive for at least one virus with influenza viruses (Flu A: ~15%; Flu B: ~9%), rhinoviruses (~8%), coronaviruses (~5%) and hRSV (~4%) being the most frequently identified. The pattern of viral infections varied according to age groups. The elucidation rate was the highest (>60%) amongst patients under 10 yo and the lowest (Bolivia in the study period, originating from Central and North America, Europe, Asia and Australia. Our results emphasise the requirement for a reinforced epidemiological and genetic follow-up of influenza and other ILIs in Bolivia to further inform the preparation of vaccines used in the region, guide vaccination campaigns and improve the medical management of patients.

    Full Text Available Tomato production through the technique of grafting aims to control soil pathogens, induce flowering, and improve tolerance to waterlogging, salinity and alkalinity of the soil. For this work were performed 50 grafts for each type of rootstock, totaling 100 slips and 50 seedlings kept as control. After 15 days of grafting, the seedlings were evaluated on the percentage of picks grafting. The treatment which used the tomato cultivar Cherry Red® as rootstock presented results of vegetative growth (height and volume Cup higher than other treatments. However after transplanting, defective development was observed for plants with grafting when compared to the controls. After 35 days of follow up, there was a low survival rate, being 5% of the plants. According to the results obtained in this work the tomato cultivar Santa Cruz Kada® has good compatibility with the rootstock cultivar Cayenne® pepper and tomato cultivar Cherry Red®

  16. Effects of environmental amenities and locational disamenities on home values in the Santa Cruz watershed: a hedonic analysis using census data

    Arora, Gaurav; Frisvold, George; Norman, Laura

    2014-01-01

    For this study, we used the hedonic pricing method to measure the effects of natural amenities on home prices in the U.S-side of the Santa Cruz Watershed. We employed multivariate spatial regression techniques to estimate how difference factors affect median home values in 613 census block groups of the 2000 Census, accounting for spatial autocorrelation, spatial lags, and/or spatial heterogeneity in the data. Diagnostic tests suggest that failure to account for the hedonic model can be classified as (1) physical features of the housing stock, (2) neighborhood characteristics, and (3) environmental attributes. Census data was combined with GIS data for vegetation and land cover, land administration, measures of species richness and open space, and proximity to amenities and disamenities. Census block groups close to the US-Mexico border of airports/air bases were negative. Results suggest that policies to maintain biodiversity and open space provide economic benefits to homeowners, reflected in higher home values. Future research will quantify the marginal effects of regression explanatory variables on home values to assess their economic and policy significant. These marginal effects will be used as input indicators to discern potential economic impacts of various scenarios in the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM). Future research will also expand this effort into the Mexican-portion of the watershed.

Aqueous compositions, fluid chemistry, transport, and mineral abundances are well characterized (White et al., 2008, GCA) and were used to constrain the reaction rates for the weathering and precipitating minerals in the reactive transport modeling. When primary mineral weathering rates are calculated with either of two experimentally determined rate constants, the nonlinear, parallel rate law formulation of Hellmann and Tisser and [2006] or the aluminum inhibition model proposed by Oelkers et al. [1994], modeling results are consistent with field-scale observations when independently constrained clay precipitation rates are accounted for. Experimental and field rates, therefore, can be reconciled at the Santa Cruz site. Observed maximum clay abundances in the argillic horizons occur at the depth and time where the reaction fronts of the primary minerals overlap. The modeling indicates that the argillic horizon at Santa Cruz can be explained almost entirely by weathering of primary minerals and in situ clay precipitation accompanied by undersaturation of kaolinite at the top of the profile. The rate constant for kaolinite precipitation was also determined based on model simulations of mineral abundances and dissolved Al, SiO{sub 2}(aq) and pH in pore waters. Changes in the rate of kaolinite precipitation or the flow rate do not affect the gradient of the primary mineral weathering profiles, but instead control the rate of propagation of the primary mineral weathering fronts and thus total

    Full Text Available Commerson's dolphins, Cephalorhynchus commersonii, suffer bycatch in fisheries and are target of dolphin-watching activities along Patagonia. Here we described dolphins' habitat use and behavioural pattern at the estuary of Santa Cruz River. Behavioural observations were made from vantage points using a spotting scope. Boat surveys were conducted randomly from Puerto Santa Cruz to the mouth of the river to analyze the habitat use. The survey area was divided into 1 km² cells and characterized with depth and benthic slope. The described behaviours for the Commerson's dolphin were: travelling, slow travelling, milling, resting, socializing, stationary swimming and diving. A new behavioural context was assigned to diving, a behaviour that showed a high frequency during downing tide, suggesting a benthic foraging strategy. Additionally, we found a strong influence of the tide on Commerson's dolphin behaviour. Habitat use models indicated that dolphins prefer shallow water inside the estuary. The knowledge of the behavioural patterns and the habitat use of these endemic species, in this unexplored area, provide tools for management and conservation purposes.

    Background Acute respiratory infections represent a serious public health issue worldwide but virological aetiologies of Influenza Like Illnesses (ILIs) remain largely unknown in developing countries. This study represents the first attempt to characterise viral aetiologies of ILIs in Bolivia. Methods It was performed in Santa Cruz city from January 2010 to September 2012, based on 564 naso-pharyngeal swabs collected in a National Reference Laboratory and real-time PCR techniques, viral cultures and phylogenetic analyses. Results 50.2% of samples were positive for at least one virus with influenza viruses (Flu A: ~15%; Flu B: ~9%), rhinoviruses (~8%), coronaviruses (~5%) and hRSV (~4%) being the most frequently identified. The pattern of viral infections varied according to age groups. The elucidation rate was the highest (>60%) amongst patients under 10 yo and the lowest (Bolivia in the study period, originating from Central and North America, Europe, Asia and Australia. Conclusion Our results emphasise the requirement for a reinforced epidemiological and genetic follow-up of influenza and other ILIs in Bolivia to further inform the preparation of vaccines used in the region, guide vaccination campaigns and improve the medical management of patients.

    Around 11.5 ∗ 106 m3 of rock detached from the eastern slope of the Santa Cruz valley (San Juan province, Argentina) in the first fortnight of January 2005. The rockslide-debris avalanche blocked the course, resulting in the development of a lake with maximum length of around 3.5 km. The increase in the inflow rate from 47,000-74,000 m3/d between April and October to 304,000 m3/d between late October and the first fortnight of November, accelerated the growing rate of the lake. On 12 November 2005 the dam failed, releasing 24.6 ∗ 106 m3 of water. The resulting outburst flood caused damages mainly on infrastructure, and affected the facilities of a hydropower dam which was under construction 250 km downstream from the source area. In this work we describe causes and consequences of the natural dam formation and failure, and we dynamically model the 2005 rockslide-debris avalanche with DAN3D. Additionally, as a volume ~ 24 ∗ 106 m3of rocks still remain unstable in the slope, we use the results of the back analysis to forecast the formation of a future natural dam. We analyzed two potential scenarios: a partial slope failure of 6.5 ∗ 106 m3 and a worst case where all the unstable volume remaining in the slope fails. The spreading of those potential events shows that a new blockage of the Santa Cruz River is likely to occur. According to their modeled morphometry and the contributing watershed upstream the blockage area, as the one of 2005, the dams would also be unstable. This study shows the importance of back and forward analysis that can be carried out to obtain critical information for land use planning, hazards mitigation, and emergency management.

    Dog overpopulation and diseases are hazards to native island species and humans on the Galapagos. Vaccination and importation of dogs are prohibited on the Galapagos. Risk management of these hazards requires the use of science-based risk assessment and risk communication. The objectives of the study reported here were (i) to estimate the human:dog ratio and (ii) the prevalence of and identify exposure factors associated with positive antibody titers to canine distemper virus (CDV) and other pathogens, as well as infection with intestinal parasites in owned dogs on Santa Cruz Island, Galapagos in September 2014. The observed human:dog ratio was 6.148:1 which extrapolates to 2503 dogs (two times more than a recent dog count conducted by Galapagos Biosecurity Agency in March 2014). The proportion of spayed female dogs (50%) was higher, compared to neutered male dogs (30%) (p=0.04). Prevalence of dogs with positive antibody titers to CDV was 36% (95% CI=26, 46%), to canine parvovirus was 89% (95% CI=82, 95%), and to canine adenovirus was 40% (95% CI=30, 51%). The frequency of seropositive dogs to CDV was lower in urban dogs (26%), compared to rural dogs (53%) (pdog population on Santa Cruz is susceptible to an outbreak of CDV (particularly among urban dogs) with potential spill over to marine mammals. Dog's age (1-2 or 3-14 years old, compared to younger dogs), and residence (rural, urban) were associated with positive antibody titers to parvovirus, adenovirus, Ehrlichia spp., or Anaplasma spp., as well as infection with Ancylostoma spp., an intestinal parasite in dogs that can be transmitted to humans, particularly children. These results provide the most comprehensive assessment of dog overpopulation and exposure to CDV and other pathogens on the Galapagos to date. Copyright © 2015 Elsevier B.V. All rights reserved.

  7. Blaming Machismo: How the Social Imaginary is Failing Men with HIV in Santa Cruz, Bolivia.

    2017-01-01

    Drawing from an ethnography of HIV care in Santa Cruz, Bolivia, in this article I explore how the social imaginary surrounding gender relations shapes men's experiences of seeking care for and living with HIV. Popular understandings of gender relations, which draw heavily on the machismo concept, intersect with a global health master narrative that frames women as victims in the AIDS epidemic in a way that generates a strong sentiment of blaming machismo within local HIV/AIDS-related services. Statements such as, "it's because of machismo" are used to explain away epidemiological trends. Participant observation in the context of HIV care, coupled with illness narrative interviews, illuminate how blaming machismo shapes men's experiences of care and the ways that they feel excluded from various forms of support. Thus, the illness experiences of men with HIV problematize the machismo concept and how it is drawn upon in the context of care.

    Full Text Available Thin sections of about 200 horizons or layers, representing 60 soil profiles in the coastal area and on the windward slopes of Isla Santa Cruz (Galápagos Islands were analysed. Based on the fabric and the composition of the groundmass and the presence of pedofeatures in individual layers or horizons, clusters of similar material are made and 7 units and 3 subunits distinguished. Plotting these units on a survey map gives a good insight in the spatial distribution of soil materials, expressing different combinations of parent material and precipitation. In the coastal area and the lowest slopes, with a summer dry climate, respectively reddish and greyish and brown materials with a porphyric c/f related distribution pattern and striated b-fabrics, and often with fragmented illuvial clay coatings are observed. The coarse material contains mainly holocrystalline basalt fragments, unweathered in the coastal area, or basalt derived individual minerals. The micromass has a halloysitic-smectitic composition. On the higher slopes, with a permanent moist climate, materials have also a porphyric or fine monic c/f related distribution pattern, but the b-fabric is undifferentiated and no illuvial features are present, gibbsitic features sometimes occur and the micromass consists mainly of halloysite and gibbsite. Subunits are distinguished here according to the microstructure, and the quantity and type of coarse material. Mesocrystalline basalt, often vesicular, dominates over holocrystalline, pointing to the influence of scoria. Soils on the higher slopes are more strongly weathered than those on the drier lower slopes and the coastal area. In depressions in the higher areas, materials with a yellowish or brownish grey micromass with a striated b-fabric, and well developed limpid illuvial clay coatings and impregnative iron oxide nodules occur. The micromass has a halloysite-smectite composition. Contrary to existing hypotheses the reddish soils in the

    McPherson, Kelly R.; Harmon, Jerry G.

    2000-01-01

    In 1998, a bathymetric survey was done to determine the storage capacity and the loss of capacity owing to sedimentation of Loch Lomond Reservoir in Santa Cruz County, California. Results of the survey indicate that the maximum capacity of the reservoir is 8,991 acre-feet in November 1998. The results of previous investigations indicate that storage capacity of the reservoir is less than 8,991 acre-feet. The storage capacity determined from those investigations probably were underestimated because of limitations of the methods and the equipment used. The volume of sedimentation in a reservoir is considered equal to the decrease in storage capacity. To determine sedimentation in Loch Lomond Reservoir, change in storage capacity was estimated for an upstream reach of the reservoir. The change in storage capacity was determined by comparing a 1998 thalweg profile (valley floor) of the reservoir with thalweg profiles from previous investigations; results of the comparison indicate that sedimentation is occurring in the upstream reach. Cross sections for 1998 and 1982 were compared to determine the magnitude of sedimentation in the upstream reach of the reservoir. Results of the comparison, which were determined from changes in the cross-sectional areas, indicate that the capacity of the reservoir decreased by 55 acre-feet.

    Full Text Available In this article, we reconstruct one of the main representation strategies and sources of power for Néstor Kichner’s leadership in Santa Cruz, Argentina between 1991 and 1996: his consolidation as a “warrantor of order and stability”. In second stance, we will analyze the social conditions that explain the success of this strategy of representation. Mainly, its affinity with a set of social attributes of the province defined as part of the “culture of suffering” and the ability of the Frente para la Victoria as an organization to embody analog values. We use for the making of this article mostly semi-structured interviews and analysis of journalistic archives. This work is a valuable study on the forms of power construction of the Frente para la Victoria since its origins, in the early 1990, a previous experience to its access of the national government in 2003.

    National Parks and other protected areas can be influenced by contamination from outside their boundaries. This is particularly true of smaller parks and those in riparian ecosystems, a habitat that in arid environments provides critical habitat for breeding, migratory, and wintering birds. Animals living in contaminated areas are susceptible to adverse health effects as a result of long-term exposure and bioaccumulation of heavy metals. We investigated the distribution and cascading extent of heavy metal accumulation in Song Sparrows (Melospiza melodia) at Tumacacori National Historic Park (TUMA) along the upper Santa Cruz River watershed in southern Arizona. This study had three goals: (1) quantify the concentrations and distributional patterns of heavy metals in blood and feathers of Song Sparrows at Tumacacori National Historic Park, (2) quantify hematocrit values, body conditions (that is, residual body mass), and immune conditions of Song Sparrows in the park (3) compare our findings with prior studies at the park to assess the extent of heavy metal accumulation in birds at downstream sites after the 2009 wastewater treatment plant upgrade, and (4) quantify concentrations and distributional patterns of heavy metals in blood and feathers of Song Sparrows among six study sites throughout the upper Santa Cruz River watershed. This study design would allow us to more accurately assess song sparrow condition and blood parameters among sites with differing potential sources of contamination exposure, and how each location could have contributed to heavy metal levels of birds in the park.

    The island factor in the cities of Las Palmas de Gran Canaria and Santa Cruz de Tenerife, their meteorology and the proximity to the African Continent that originates the natural particulate matter transport over the islands, cause some specific features in their air quality. The aim of this paper is to characterize the air pollution from 2000 to 2004 as exposure indicator of both cities inhabitants. 24 hour daily average variables of PM10, PM2,5, NO2, SO2 and O3 , 8 hours daily maxima moving averages of O3 y CO and 1 hour maxima of SO2, NO2, O3, CO, PM10 y PM2,5 were calculated. Daily levels of coarse particles were obtained subtracting PM2,5 from PM10. African dust events were identified. In Sta. Cruz de Tf daily means of SO2 (14.0 microg/m(3)N) and ozone levels (44.4 microg/m(3)N ) were higher than Las Palmas de GC levels (8.0 y 28.3 microg/m(3)N). Daily means of NO2 in Las Palmas de GC: 45.8 microg/m(3)N where higher than Sta. Cruz de Tf levels: 30.3 microg/m(3)N. Due to African dust outbreaks, some days in both cities exceeded 600 microg/m(3) of PM10 and 200 of PM2.5 24-h average. The air quality patterns were characterized by very high levels of African dust outbreaks that affect all PM size fractions. Different O3 seasonality exists respect European cities in addition to an urban-industrial ambient air in Sta. Cruz de TF and clearly urban in Las Palmas de GC. These results have to be considered in order to lay the foundations to suitable surveillance systems, analyse the potential impact on the Canary Islands citizens health and to get conclusions.

    Full Text Available The work was developed in the Los Amaros, the Santa Cruz river, Artemisa, Cuba. The objective was to evaluate how it influences the expansion of the agricultural frontier on riparian vegetation where the semi-deciduous mesophytic forest (BsdMe predominates. A floristic characterization was performed, identifying the effects of disturbances on the structure and composition of these forests and their relation to human disturbance. A semi-structured interview was applied to all landowners in the study area. Species richness, dominance, basal area, total number of individuals, width of the strip covered by trees and shrubs, and area without vegetation on both banks of the river, respectively were considered as variables. There are differences in the structure and patterns of diversity of the studied forest, as a result of disturbances, with the consequent reduction of species; also anthropogenic disturbances, are the main factors that explain changes in the structure of these forests. They are identified as major species: Cupania macrophylla A. Rich., Roystonea regia HBK O. F. Cook., Guarea guidonia L. Sleumer and Trichilia hirta  L. It is proposed to deepen the effect of the expansion of agriculture into other sectors of the river in interaction with local communities.

As an example, we comment some results obtained from the excavation of the floor of the church of Our Lady of the Conception, where the deads of Santa Cruz de Tenerife were interred during centuries. Despite the poor preservation of the skeletons, it has been possible to infer dietary habits, toxic exposure, nutritional status and genetic lineages (mitochondrial DNA. Smoking pipes, ceramics and adornments associated with interments show a high similitude with those from colonial sites of the New World.

    Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is determined by multiple factors affecting it. In U.S. portions of the bi-national Santa Cruz Watershed (SCW), situated at the Arizona-Sonora International border, natural amenities like the riparian corridor and green space have been documented as positive amenities that boost local real estate.

    Full Text Available The brutal decline of the Imperial Colegio de Santa Cruz, after a bright but brief career, has spurred many papers and reflections. This one focuses on the economic factors, frequently ignored, that participated in its ruin. Indeed, the Colegio was stripped of its most precious assets by a few individuals belonging to the rising oligarchy of original settlers and conquerors' descendants, supported in turn by the highest authorities' --Real Audiencia, Real Hacienda, and even the viceroy Luis de Velasco the Elder, with whom they held family ties-- disregard and/or passive, or even active, complicity.

    Full Text Available Justificativa e Objetivos: A tuberculose (TB, doença infectocontagiosa, é atualmente um problema de saúde pública no Brasil e no mundo, integrando a Lista Nacional de Agravos de Notificação Compulsória. Devido à alta incidência verificada, a cidade de Santa Cruz do Sul configura um dos municípios prioritários no controle de notificação da doença no estado do Rio Grande do Sul. Nesse contexto, as Estratégias de Saúde da Família (ESF são contribuintes importantes do processo de notificação, por serem cada vez mais utilizadas como portas de entrada do sistema de saúde e como pontos de controle da doença. Este estudo tem como objetivo estabelecer a prevalência da notificação dos casos de TB nas ESF em Santa Cruz do Sul. Métodos: O estudo realizado foi observacional, de caráter transversal. Foram utilizados dados dos consolidados das famílias cadastradas em 11 ESF na cidade de Santa Cruz do Sul, referentes ao ano de 2013. Resultados: O total de casos notificados foi 17, sendo que todos possuíam 15 anos ou mais de idade. O documento não especificava o sexo dos indivíduos notificados. A prevalência de tuberculose, no total de ESF analisadas, foi de 0,51/1000 pessoas cadastradas. Conclusão: A taxa elevada de casos de TB no município pode estar relacionada a um aumento na qualidade da busca ativa dos pacientes, levando a um número elevado de notificações pelas ESF. Essa taxa elevada de notificações é relevante, uma vez que atenta para a importância das ESF na elaboração e adoção de medidas preventivas.

  15. Description of a New Galapagos Giant Tortoise Species (Chelonoidis; Testudines: Testudinidae from Cerro Fatal on Santa Cruz Island.

    Full Text Available The taxonomy of giant Galapagos tortoises (Chelonoidis spp. is currently based primarily on morphological characters and island of origin. Over the last decade, compelling genetic evidence has accumulated for multiple independent evolutionary lineages, spurring the need for taxonomic revision. On the island of Santa Cruz there is currently a single named species, C. porteri. Recent genetic and morphological studies have shown that, within this taxon, there are two evolutionarily and spatially distinct lineages on the western and eastern sectors of the island, known as the Reserva and Cerro Fatal populations, respectively. Analyses of DNA from natural populations and museum specimens, including the type specimen for C. porteri, confirm the genetic distinctiveness of these two lineages and support elevation of the Cerro Fatal tortoises to the rank of species. In this paper, we identify DNA characters that define this new species, and infer evolutionary relationships relative to other species of Galapagos tortoises.

    To estimate the frequency of and risk factors for surgical-site infections (SSIs) in Bolivia, and to study the performance of the National Nosocomial Infections Surveillance (NNIS) System risk index in a developing country. A prospective study with patient follow-up until the 30th postoperative day. A general surgical ward of a public hospital in Santa Cruz, Bolivia. Patients admitted to the ward between July 1998 and June 1999 on whom surgical procedures were performed. Follow-up was complete for 91.5% of 376 surgical procedures. The overall SSI rate was 12%. Thirty-four (75.6%) of the 45 SSIs were culture positive. A logistic regression model retained an American Society of Anesthesiologists score of more than 1 (odds ratio [OR], 1.87), a not-clean wound class (OR, 2.28), a procedure duration of more than 1 hour (OR, 1.81), and drain (OR, 1.98) as independent risk factors for SSI. There was no significant association between the NNIS System risk index and SSI rates. However, a "local" risk index constructed with the above cutoff points showed a linear trend with SSI (P < .001) and a relative risk of 3.18 for risk class 3 versus a class of less than 3. SSIs cause considerable morbidity in Santa Cruz. Appropriate nosocomial infection surveillance and control should be introduced. The NNIS System risk index did not discriminate between patients at low and high risk for SSI in this hospital setting, but a risk score based on local cutoff points performed substantially better.

    It is not uncommon to have several rare and listed taxa occupying habitats in one landscape or management area where conservation amounts to defense against the possibility of further loss. It is uncommon and extremely exciting, however, to have several listed taxa occupying one island that is managed cooperatively for conservation and recovery. On Santa Cruz Island, the largest of the northern California island group in the Santa Barbara Channel, we have a golden opportunity to marry ecological knowledge and institutional "good will" in a field test of holistic rare plant conservation. Here, the last feral livestock have been removed, active weed control is underway, and management is focused on understanding and demonstrating system response to conservation management. Yet funding limitations still exist and we need to plan the most fiscally conservative and marketable approach to rare plant restoration. We still experience the tension between desirable quick results and the ecological pace of system recovery. Therefore, our research has focused on identifying fundamental constraints on species recovery at individual, demographic, habitat, and ecosystem levels, and then developing suites of actions that might be taken across taxa and landscapes. At the same time, we seek a performance middle ground that balances an institutional need for quick demonstration of hands-on positive results with a contrasting approach that allows ecosystem recovery to facilitate species recovery in the long term. We find that constraints vary across breeding systems, life-histories, and island locations. We take a hybrid approach in which we identify several actions that we can take now to enhance population size or habitat occupancy for some taxa by active restoration, while allowing others to recover at the pace of ecosystem change. We make our recommendations on the basis of data we have collected over the last decade, so that management is firmly grounded in ecological observation.

    Trypanosoma cruzi (Tc) infection is usually acquired in childhood in endemic areas, leading to Chagas disease, which progresses to Chagas cardiomyopathy in 20-30% of infected individuals over decades. The pathogenesis of Chagas cardiomyopathy involves the host inflammatory response to T. cruzi, in which upstream caspase-1 activation prompts the cascade of inflammatory chemokines/cytokines, cardiac remodeling, and myocardial dysfunction. The aim of the present study was to examine the association of two caspase-1 single nucleotide polymorphisms (SNPs) with cardiomyopathy. We recruited infected (Tc+, n = 149) and uninfected (Tc-, n = 87) participants in a hospital in Santa Cruz, Bolivia. Cardiac status was classified (I, II, III, IV) based on Chagas cardiomyopathy-associated electrocardiogram findings and ejection fractions on echocardiogram. Genotypes were determined using Taqman probes via reverse transcription-polymerase chain reaction of peripheral blood DNA. Genotype frequencies were analyzed according to three inheritance patterns (dominant, recessive, additive) using logistic regression adjusted for age and sex. The AA allele for the caspase-1 SNP rs501192 was more frequent in Tc+ cardiomyopathy (classes II, III, IV) patients compared to those with a normal cardiac status (class I) [odds ratio (OR) = -2.18, p = 0.117]. This trend approached statistical significant considering only Tc+ patients in class I and II (OR = -2.64, p = 0.064). Caspase-1 polymorphisms may play a role in Chagas cardiomyopathy development and could serve as markers to identify individuals at higher risk for priority treatment.

    In the Central Andes of Argentina, ephemeral river blockage due to landslides deposition are common phenomena. During the first fortnight of January 2005, 11.5 * 106m3 of rock collapsed from the east slope of the Santa Cruz valley (San Juan province, Argentina). The rock mass displaced from 4300 m a.s.l., down to the valley bottom, at 2900 m a.s.l., and ran up the opposite flank of the valley. This produced the blockage of the Santa Cruz river and generated the Los Erizos lake. The rapid snow melting during the spring season caused the increase of the water level of the reservoir, leading to a process of overtopping on November 12th of 2005. 30 * 106m3 of water were released from the reservoir and the consequent outburst flood displaced along 250 km. From local reports of arrival times, we estimated that the outburst flood reduced its velocity from around 40 km/h near the source area to 6 km/h in its distal section. A road, bridges, and a mining post where destroyed. 75 tourists had to be rescued from the mountains using helicopters, and people from two localities had to be evacuated. Near its distal part, the flood damaged the facilities of the Caracoles power dam, which was under construction, and its inauguration had to be delayed one year due to the damage. The outburst flood produced changes in the morphology of the valley floor along almost all its path (erosion of alluvial fans, talus and terraces, and deposition of boulders). The most significant changes occurred in the first 70 km, especially upstream narrow sections, showing the importance of the backwater effects due to hydraulic ponding. In this work we carried out numerical simulations to obtain the velocity patterns of the flood, and compared them with those obtained from local reports. Furthermore, we analyze the relationship between the dynamics of the flood with the patterns of erosion and deposition near the source area.

    Among approximately 2,000 mammals examined for helminths in various regions of Bolivia during 1983-1987, cysts of Echinococcus vogeli Rausch and Bernstein, 1972, were found in a single paca, Cuniculus paca L., collected at La Laguna, Departamento de Santa Cruz (lat. 16 degrees 36'W; long. 62 degrees 42'S). This record, the first from Bolivia, represents a considerable extension of the known geographic range of this species in South America. Upon analysis of the morphologic characteristics of the protoscoleces derived from the cysts, the sizes of rostellar hooks from the material from the paca were found to be well within the ranges reported in previous studies. Statistical analysis of frequency distributions of hook characteristics revealed some deviations from normality. These results indicate that parametric statistics should be applied with caution in analyses of inter-and intraspecific variation of morphologic characteristics of hooks of metacestodes of the genus Echinococcus.

  11. Processes of Terrace Formation on the Piedmont of the Santa Cruz River Valley During Quaternary Time, Green Valley-Tubac Area, Southeastern Arizona

    Lindsey, David A.; Van Gosen, Bradley S.

    2010-01-01

    In this report we describe a series of stepped Quaternary terraces on some piedmont tributaries of the Santa Cruz River valley in southeastern Arizona. These terraces began to form in early Pleistocene time, after major basin-and-range faulting ceased, with lateral planation of basin fill and deposition of thin fans of alluvium. At the end of this cycle of erosion and deposition, tributaries of the Santa Cruz River began the process of dissection and terrace formation that continues to the present. Vertical cutting alternated with periods of equilibrium, during which streams cut laterally and left thin deposits of channel fill. The distribution of terraces was mapped and compiled with adjacent mapping to produce a regional picture of piedmont stream history in the middle part of the Santa Cruz River valley. For selected tributaries, the thickness of terrace fill was measured, particle size and lithology of gravel were determined, and sedimentary features were photographed and described. Mapping of terrace stratigraphy revealed that on two tributaries, Madera Canyon Wash and Montosa Canyon Wash, stream piracy has played an important role in piedmont landscape development. On two other tributaries, Cottonwood Canyon Wash and Josephine Canyon Wash, rapid downcutting preempted piracy. Two types of terraces are recognized: erosional and depositional. Gravel in thin erosional terraces has Trask sorting coefficients and sedimentary structures typical of streamflood deposits, replete with bar-and-swale surface topography on young terraces. Erosional-terrace fill represents the channel fill of the stream that cuts the terrace; the thickness of the fill indicates the depth of channel scour. In contrast to erosional terraces, depositional terraces show evidence of repeated deposition and net aggradation, as indicated by their thickness (as much as 20+ m) and weakly bedded structure. Depositional terraces are common below mountain-front canyon mouths where streams drop their

Los promedios de NO2 en Las Palmas de GC: 45,8 ug/m3N fueron superiores a los de Sta. Cruz de TF: 30,3 ug/m3N. Debido a las intrusiones africanas, algunos días superaron los 600 ug/m3 de PM10 y los 200 de PM2.5 en ambas ciudades. Conclusiones: Se identifica un patrón de calidad del aire con episodios de polvo mineral africano que en superficie afecta a todas las fracciones granulométricas, una estacionalidad diferente a las ciudades europeas respecto al ozono, así como un patrón de contaminación urbano-industrial en Sta. Cruz de Tf y netamente urbano en Las Palmas de GC. Se hace necesario tener en cuenta estos resultados para analizar su posible impacto sobre la salud de los ciudadanos de las Islas Canarias y establecer sistemas adecuados de vigilancia.

    In the present paper, zinc sheets have been exposed for 4 years to the action of different atmospheres in 35 test sites located in the province of Santa Cruz de Tenerife, Canary Islands, Spain. Corrosion products formed on the surface of the samples have been identified by means of X-ray diffraction (XRD) for the first and second year of exposure. Zincite, hydrozincite, simonkolleite, zinc chlorohydroxysulphate, zinc oxysulphate and zinc hydroxysulphate have been identified in the test sheets. Preliminary results of an electrochemical study of the breakdown potential of zinc samples are also presented in order to test the protective effect of the film formed on the surface of the samples. It was found that the protective effect of this film increases linearly with exposure time.

    Santa Cruz Island is the largest of the California Channel Islands and supports a diverse and unique flora which includes 9 federally listed species. Sheep, cattle, and pigs, introduced to the island in the mid-1800s, disturbed the soil, browsed native vegetation, and facilitated the spread of exotic invasive plants. Recent removal of introduced herbivores on the island led to the release of invasive fennel (Foeniculum vulgare), which expanded to become the dominant vegetation in some areas and has impeded the recovery of some native plant communities. In 2007, Channel Islands National Park initiated a program to control fennel using triclopyr on the eastern 10% of the island. We established replicate paired plots (seeded and nonseeded) at Scorpion Anchorage and Smugglers Cove, where notably dense fennel infestations (>10% cover) occurred, to evaluate the effectiveness of native seed augmentation following fennel removal. Five years after fennel removal, vegetative cover increased as litter and bare ground cover decreased significantly (P species increased at Scorpion Anchorage in both seeded and nonseeded plots. At Smugglers Cove, exotic cover decreased significantly (P = 0.0001) as native cover comprised of Eriogonum arborescensand Leptosyne gigantea increased significantly (P < 0.0001) in seeded plots only. Nonseeded plots at Smugglers Cove were dominated by exotic annual grasses, primarily Avena barbata. The data indicate that seeding with appropriate native seed is a critical step in restoration following fennel control in areas where the native seed bank is depauperate.

    Full Text Available The tomato is one of the most important vegetable, economical and nutritionally, around the world. For this reason the germination process in the tomato is a vital stage in the growth and development of plants. In this study, the effect of different doses of gibberellin over the germination of Santa Cruz variety tomato seeds was evaluated. The seeds were embedded for 24 hours in different concentrations of gibberellic acid, sown in a peat substrate in the screen house of the UPTC. A complete randomized design was used with 4 treatments corresponding to 0, 100, 200 and 400 mg L-1 of GAs with three replicates, for a total of 12 experimental units (EU, and each unit with 35 seeds. The treatment of 0 mg L-1 had a favorable impact on the mean germination time (GT, average speed of germination (ASG and germination percentage (GP, showing significant differences with respect to the other treatments. The seeds soaked in 400 mg L-1 of GAs presented the lowest values in the variables GT, ASG and GP, attributed to negative effect this type of hormone over this tomato variety, which delayed the death of the embryo and the seed germination.

    Heavy metals are persistent environmental contaminants, and transport of metals into the environment poses a threat to ecosystems, as plants and wildlife are susceptible to long-term exposure, bioaccumulation, and potential toxicity. We investigated the distribution and cascading extent of heavy metal accumulation in southwestern song sparrows (Melospiza melodia fallax), a resident riparian bird species that occurs along the US/Mexico border in Arizona’s upper Santa Cruz River watershed. This study had three goals: (1) quantify the degree of heavy metal accumulation in sparrows and determine the distributional patterns among study sites, (2) compare concentrations of metals found in this study to those found in studies performed prior to a 2009 international wastewater facility upgrade, and (3) assess the condition of song sparrows among sites with differing potential levels of exposure. We examined five study sites along with a reference site that reflect different potential sources of contamination. Body mass residuals and leukocyte counts were used to assess sparrow condition. Birds at our study sites typically had higher metal concentrations than birds at the reference site. Copper, mercury, nickel, and selenium in song sparrows did exceed background levels, although most metals were below background concentrations determined from previous studies. Song sparrows generally showed lower heavy metal concentrations compared to studies conducted prior to the 2009 wastewater facility upgrade. We found no cascading effects as a result of metal exposure.

    Background In the context of a rapid increase of dengue cases in the Americas, a monitoring system based on systematic serological control (IgM) of patients consulting for suspected dengue was developed in Bolivia at the end of the 1990s. In the most affected city of Santa Cruz, this system was complemented by an entomological surveillance program based on periodical search for immature stages of Aedes aegypti in dwelling water-holding containers. Here, we analyze these data and describe dengue patterns over 6 years (2002–2008), highlighting the spatial distribution of patients and vectors. Methodology /Principal Findings Data mining concerned six annual epidemic cycles (2002–2008), with continuous serological and clinical results and entomological data from 16 surveys, examined at the scales of 36 urban areas and four concentric areas covering the entire city. Annual incidence varied from 0.28‰ to 0.95‰; overall incidence was higher in women and adults, and dengue dynamics followed successive periods of high (January–June) and low (July–December) transmission. Lower numbers of cases from the city center to the periphery were observed, poorly related to the more homogeneous and permanent distribution of A. aegypti. "Plant pots" were a major vector source in the city center, and "Tires" and "Odds and ends" beyond the second ring of the city. Conclusions/Significance Over the years, the increasing trend of dengue cases has been highlighted as well as its widespread distribution over the entire city, but an underestimation of the number of cases is strongly suspected. Contrary to popular belief, the city center appears more affected than the periphery, and dengue is not particularly related to waste. Interestingly, the clinical diagnosis of dengue by physicians improved over the years, whatever the gender, age and residential area of suspected cases. PMID:25706631

    The Hazel Dell site provides the first definitive paleoseismic evidence of two pre-1906 19th century events on the Santa Cruz Mountains section based on the presence of anthropogenic artifacts. Hundreds of pieces of cut redwood chips were found in a stratigraphic horizon just below the ante-penultimate (E3) earthquake surface, suggesting that redwood trees at the site were cut down right before earthquake E3. We correlate our paleoseismic findings with the historic record and the onset of redwood logging in the area by determining the felling date of a buried redwood tree stump at the site and the age of the woodchips. We wiggle match 14 radiocarbon dates sampled from annual growth rings taken from the stump and the known interval between growth rings, with the intercepts of the INTCAL04 terrestrial 14C calibration curve. Pending 13C measurements, we find that the youngest ring we have identified in the tree is A.D. 1800. We also wiggle match 2 radiocarbon dates from inner and outer growth rings from two wood chips (with bark); their ages are consistent with the tree and the youngest woodchip ring is dated to 1813 A.D. There are no known ethnographic or historical accounts of pre-contact native people felling large trees in the way that European colonists did. The first record of European land use was for pasture in 1803. The property became a Spanish land grant in 1827, soon after which a whip-saw lumber mill is documented to have begun operation in the upper Corralitos area. We combine these paleoseismic results with historical earthquake accounts for the area and conclude that the San Andreas fault ruptured in 1838, 1890 and 1906. The Hazel Dell results are in contrast with findings from earlier paleoseismic studies in the Santa Cruz Mountains. The Grizzly Flat site, 6 km to the north, found evidence of 1906 and one 17th century earthquake. Two historic earthquakes were observed at the Mill Canyon site 8 km to the south and at the Arano Flat site 9.5 km south of

    Full Text Available The basic sanitation comprises several services that are essential to the maintenance of people's health and well-being. The populations that have an appropriate water supply, sewage collection and treatment, proper garbage disposal, among other services, are protected from diseases and have access to a minimum comfort to live in a safe way. In spite of the importance of these services, to the extent to be characterized as “basic”, several populations, national or worldwide, suffer for the lack or the complete privation of sanitation, live without access to quality water, their waste is thrown under open air and their garbage is disposed in inappropriate sites, what causes health and environmental impacts. This work is being accomplished in a community called Santa Cruz, located in Campos dos Goytacazes, RJ, and aims to carry out a survey about the local sanitary reality, especially about the quality of the water supplied to the population. 100 inhabitants of that community were interviewed and answered a questionnaire. Among the results, 22% of the interviewees consume the water that comes to their homes without any type of treatment, 47% consider the supply water as being of poor quality and 7% don't own home water tanks. After the interviews, bacteriological and physicochemical water analyses were performed in fifteen samples collected in the community. The test results indicated that the collected water was out of the drinking water standards, and therefore, inappropriate for human consumption.

Using a multi-observational approach to land-change analysis that included landownership data as a proxy for land-use practices, multitemporal land-cover maps, and repeat photography dating to the late 19th century, we examine changing spatial and temporal distributions of two vegetation types with high conservation value in the southwestern United States: grasslands and riparian vegetation. Our study area is the bi-national Santa Cruz Watershed, a topographically complex watershed that straddles the Sonoran Desert and the Madrean Archipelago Ecoregions. In this presentation we focus on historical changes in vegetation and land use in grasslands and riparian areas of the Madrean Ecoregion (San Raphael Valley, Cienega Creek, Sonoita), and compare changes in these areas to changes in the warmer and drier Sonoran Ecoregion. Analysis of historical photography confirms major 20th century vegetation shifts documented in other research: woody plant encroachment, desertification of grasslands, and changing riparian and xeroriparian vegetation occurred in both ecoregions following human settlement. However, vegetation changes over the past decade appear to be more subtle and some of the past trajectories appear to be reversing; most notable are recent mesquite declines in xeroriparian and upland areas, and changes from shrubland to grassland area in the Madrean ecoregion. Land cover changes were temporally variable, reflecting broad climate changes. The most dynamic cover changes occurred during the period from 1989 to 1999, a period with two intense droughts.

    Samples of ground drill cores from the southern part of the Santa Cruz porphyry copper deposit, Casa Grande, Arizona, were oxidized in simulated weathering experiments. The samples were also separated into various mineral fractions and analyzed for contents of metals and sulfide minerals. The principal sulfide mineral present was pyrite. Gases produced in the weathering experiments were measured by gas chromatography. Carbon dioxide, oxygen, carbonyl sulfide, sulfur dioxide and carbon disulfide were found in the gases; no hydrogen sulfide, organic sulfides, or mercaptans were detected. Oxygen concentration was very important for production of the volatiles measured; in general, oxygen concentration was more important to gas production than were metallic element content, sulfide mineral content, or mineral fraction (oxide or sulfide) of the sample. The various volatile species also appeared to be interactive; some of the volatiles measured may have been formed through gas reactions. ?? 1990.

    Full Text Available Entre as dez primeiras causas de anos vividos com incapacidade no mundo, sete são transtornos mentais. Centros de atendimento primário são fundamentais para as políticas de saúde mental, conforme a Organização Mundial da Saúde. Este estudo tem por objetivo verificar a prevalência de transtornos mentais entre indivíduos que buscaram atendimento médico na unidade de referência de uma equipe do Programa Saúde da Família (PSF em Santa Cruz do Sul, Rio Grande do Sul, Brasil, e verificar a influência de diagnóstico psiquiátrico na utilização de recursos da saúde. Dos 754 indivíduos que participaram do estudo, 51,1% (IC95%: 47,5-54,7 foram diagnosticados como portadores de diagnóstico psiquiátrico, sendo que estes utilizaram de forma significativamente mais freqüente recursos da saúde nos últimos 12 meses. Transtornos mentais representam impacto negativo na qualidade de vida e bem-estar dos portadores, assim como aumento de uso dos recursos da saúde por sintomas não tratados e por ser fator de mau prognóstico para outras doenças não-psiquiátricas. Esses resultados reforçam a necessidade da inclusão efetiva do tema saúde mental nas metas e intervenções dos PSFs no Brasil.Among the ten leading causes of disability-adjusted life years, seven are mental disorders.

    Twenty to thirty percent of persons with Trypanosoma cruzi infection eventually develop cardiomyopathy. If an early indicator were to be identified and validated in longitudinal studies, this could enable treatment to be prioritized for those at highest risk. We evaluated cardiac and extracellular matrix remodeling markers across cardiac stages in T. cruzi infected (Tc+) and uninfected (Tc-) individuals. Participants were recruited in a public hospital in Santa Cruz, Bolivia and assigned cardiac severity stages by electrocardiogram and echocardiogram. BNP, NTproBNP, CKMB, troponin I, MMP-2, MMP-9, TIMP-1, TIMP-2, TGFb1, and TGFb2 were measured in specimens from 265 individuals using multiplex bead systems. Biomarker levels were compared between Tc+ and Tc- groups, and across cardiac stages. Receivers operating characteristic (ROC) curves were created; for markers with area under curve>0.60, logistic regression was performed. Analyses stratified by cardiac stage showed no significant differences in biomarker levels by Tc infection status. Among Tc+ individuals, those with cardiac insufficiency had higher levels of BNP, NTproBNP, troponin I, MMP-2, TIMP-1, and TIMP-2 than those with normal ejection fraction and left ventricular diameter. No individual marker distinguished between the two earliest Tc+ stages, but in ROC-based analyses, MMP-2/MMP-9 ratio was significantly higher in those with than those without ECG abnormalities. BNP, NTproBNP, troponin I, MMP-2, TIMP-1, and TIMP-2 levels rose with increasing severity stage but did not distinguish between Chagas cardiomyopathy and other cardiomyopathies. Among Tc+ individuals without cardiac insufficiency, only the MMP-2/MMP-9 ratio differed between those with and without ECG changes.

    The eastern domain of Marajo Island, in the surroundings of Santa Cruz do Arari (Para State), is occupied by holocenic sedimentary deposits, at present covered predominantly by natural grasslands. The analysis of stable carbon isotopes in organic matter of these sediments has been applied with the objective of to evaluate the paleovegetation dynamics, the retreat or the expansion of the Amazonian Forest (located in the westerner domain) over the different types of natural grasslands in Marajo Island, during Late Quaternary. From 3.60 m to 1.80 m the δ 13 C results are around -25 (reaching value up to -29 per mille) and indicate that the organic matter of these sediments are originated from C3 plants. In the interval of 1.80 m until 0.90 m all the samples present a gradual enrichment of 13 C, indicating a higher influence of C4 plants in the vegetation cover. The intermediate δ 13 C values found in those depths (from -22 per mille to -18 per mille) indicate a mixture of C3 and C4 plants with gradual increase of areas with C4 plants. From 0.90 m to the shallow layer the δ 13 C values show a tendency to more depleted values, indicating higher influence of C3 plants in the recent and present period. The results demonstrate that the vegetation dynamics was significant in the Marajo Island from the past to the present. The chronology of these events is being determined by the 14 C dating technique and possible causes (climatic, anthropogenic and/or neotectonic) for such changes investigate. (author)

    Full Text Available Rationale and Objectives: Healthcare workers are constantly exposed to the risk of occupational accidents involving biological material. Thus the aim of the study was to develop a profile of workers involved in workplace accidents with biological materials in Santa Cruz do Sul, through the number of notifications made in information systems. Methods: Transversal retrospective study with a quantitative approach; data collection was carried out between the years 2008 and 2010 from medical records in the Municipal Reference Occupational Health Unit – UMREST – containing the notification via Individual Report of Accident Notification - RINA, and/or Work Accident Communication - CAT. Results: A total of 1,263 records were analyzed during the study period. There were 13 notifications in 2008, 7 cases in 2009 and 2 in 2010. Five records had CAT, 8 had RINA and 9 had RINA and CAT. The most frequently affected professional category was the nursing technician, with the highest frequency in 2008, followed by dentists and nurses. There was a higher prevalence of female workers, with 18 cases. The most prevalent age group was 20 to 49 years old. Conclusion: The study showed that women working in the nursingprofession at the productive-age group are the ones most often affected by work accidents involving biological material during the study period. The study results raise the suspicion of underreporting of accidents with biological material, considering the number of notifications in thesetting of records found in the investigated UMREST.

    Full Text Available On April 29, 2003, a catastrophic flood occurred in the Argentina city of Santa Fe de la Vera Cruz. Soon, the disaster became a political issue, as they had made serious accusations against the authorities and decision makers regarding negligence, corruption and lack of disaster preparedness. A local protest movement emerged, claiming both the allocation of responsibilities and financial compensation for the losses suffered by the victims. This article analyses the role of material memory and oblivion on the post disaster scene, more specifically, how different social actors in Santa Fe used places and objects in the contentious making of a disaster memoryscape. The analysis is based on ethnography from transtemporal translocal and field research conducted in Santa Fe between 2004 and 2011, and applies anthropological and sociological theories of memory to analyse these processes. Resumen El 29 de abril de 2003, ocurrió la peor inundación catastrófica en la historia de la ciudad argentina de Santa Fe de la Vera Cruz. Al poco tiempo, el desastre se convirtió en una cuestión política, ya que se habían realizado graves acusaciones contra las autoridades y tomadores de decisiones con respecto a la negligencia, la corrupción y la falta de preparación para desastres. Surgió un movimiento de protesta demandando tanto la asignación de responsabilidades, como la compensación económica por las pérdidas sufridas por las víctimas. Este artículo analiza el papel de la memoria material y el olvido en el escenario del posdesastre, y más específicamente cómo los diferentes actores sociales en Santa Fe usaron los lugares y los objetos en una contienda por construir un memo-paisaje del desastre. El análisis se basa en etnografía de trabajo de campo translocal y transtemporal realizado en Santa Fe entre 2004 y 2011, y aplica las teorías antropológicas y sociológicas de la memoria a fines de analizar estos procesos.

    Full Text Available The aim of this study was to verify possible differences in the levels of physical activity related to the socio-economic conditions of schoolchildren in the municipality of Santa Cruz do Sul-RS. It is of transversal-descriptive character, and its subjects are 350 schoolchildren, aged 7 to 17, of both genders. For data collection a previously validated and adapted questionnaire was used, while the chi-quadrat-test was used for statistical analysis. Significant statistical differences were detected in the manner of locomotion, with regard to the school level and socio-economic status, for both genders. The results showed that students from urban areas and of inferior socio-economic levels showed more active in this respect. In the practice of physical activities, the results pointed to a reverse relation of this variable with the socio-economic level. At school level, a prevalence of inactive subjects from the rural area was observed. The difference in the form of locomotion and the physical activities of the evaluated schoolchildren, both at school level and at their socio-economic level, demonstrates different profiles of schoolchildren, which should be considered in future intervention programs.

  2. Use of remotely sensed imagery to map Sudden Oak Death (Phytophthora ramorum) in the Santa Cruz Mountains

    Science.gov (United States)

    Gillis, Trinka

    This project sought a method to map Sudden Oak Death distribution in the Santa Cruz Mountains of California, a coastal mountain range and one of the locations where this disease was first observed. The project researched a method to identify forest affected by SOD using 30 m multi-spectral Landsat satellite imagery to classify tree mortality at the canopy-level throughout the study area, and applied that method to a time series of data to show pattern of spread. A successful methodology would be of interest to scientists trying to identify areas which escaped disease contagion, environmentalists attempting to quantify damage, and land managers evaluating the health of their forests. The more we can learn about the disease, the more chance we have to prevent further spread and damage to existing wild lands. The primary data source for this research was springtime Landsat Climate Data Record surface reflectance data. Non-forest areas were masked out using data produced by the National Land Cover Database and supplemental land cover classification from the Landsat 2011 Climate Data Record image. Areas with other known causes of tree death, as identified by Fire and Resource Assessment Program fire perimeter polygons, and US Department of Agriculture Forest Health Monitoring Program Aerial Detection Survey polygons, were also masked out. Within the remaining forested study area, manually-created points were classified based on the land cover contained by the corresponding Landsat 2011 pixel. These were used to extract value ranges from the Landsat bands and calculated vegetation indices. The range and index which best differentiated healthy from dead trees, SWIR/NIR, was applied to each Landsat scene in the time series to map tree mortality. Results Validation Points, classified using Google Earth high-resolution aerial imagery, were created to evaluate the accuracy of the mapping methodology for the 2011 data.

    Full Text Available El valle de Toluca se localiza en la cuenca hidrológica Lerma-Chapala-Santiago, la más extensa de la República Mexicana. A lo largo de su milenaria historia, ha sido reconocido por ser una región donde se encuentran tres ciénagas (Chignahuapan, Chimaliapan y Chicnahuapan, circundadas por volcanes y densos bosques además del río Lerma. La riqueza ambiental de este frío valle favoreció la temprana ocupación de la región, cuyas evidencias arqueológicas se remontan, por lo menos, hasta hace más de 3000 años, durante el Formativo temprano. Hacia 500/600 d. C., las condiciones climáticas se volvieron más secas, provocando el descenso del nivel de agua de las lagunas y permitiendo la colonización del interior de las ciénagas. El sitio arqueológico Santa Cruz Atizapán constituye uno de los asentamientos lacustres que se fundaron en esta zona. Este artículo se enfoca en él, donde los antiguos pobladores se adaptaron a las condiciones del terreno cenagoso y lo transformaron en un lugar habitable, construyendo unos cien montículos sobre los cuales levantaron sus casas-habitaciones. Trata, también, acerca del modo de vida lacustre, donde prevalece la relación simbiótica del hombre con su medio, y sobre el intercambio de productos con otras regiones, que destacan por considerarse de gran relevancia en el desarrollo y consolidación del sitio como centro rector. A pesar de que los montículos dentro de la ciénaga fueron abandonados a fines del Epiclásico cuando las condiciones climáticas provocaron nuevamente un ascenso en el nivel del agua, la parte nuclear del sitio Santa Cruz Atizapán continuó funcionando durante el Posclásico como uno de los centros regionales importantes.

    We present eleven Apatite Fission Track (AFT) and Apatite (U-Th)/He (A-He) analyses and eighteen catchment-averaged cosmogenic 10Be denudation rates from the Santa Cruz Mountains (SCM) that resolve the unroofing history of this range over the past several Myr. This range lies within a restraining bend in the San Andreas Fault (SAF), which appears to be fixed to the crust on the northeast side of the fault based on previous work. In this view, the topographic asymmetry of the SCM reflects the advection of material southwest of the right-lateral SAF through a zone of uplift centered on the restraining bend, while material northwest of the fault remains trapped this zone. Northeast of the fault bend in the Sierra Azul block of the SCM, AFT ages adjacent to the SAF appear completely reset during the Pliocene, and show partial resetting at the periphery of the block. This suggests that total exhumation exceeded 3-4 km within the heart of the block and was SCM are near mass flux steady state over the timescales captured by the CRN (~1.5-6.5 ka). Nonetheless, the extent of topography in areas far from the bend suggests that there may be some component of regional fault-normal contraction and/or that this steady state has not been fully attained because of geomorphic lags and isostatic adjustments.

    Riparian ecosystems in arid environments provide critical habitat for breeding, migratory, and wintering birds, yet are often at risk of contamination by heavy metals. Birds and other animals living in contaminated areas are susceptible to adverse health effects as a result of long-term exposure and bioaccumulation of heavy metals. We investigated the distribution and cascading extent of heavy metal accumulation in Song Sparrows (Melospiza melodia) in Arizona’s upper Santa Cruz River watershed. This study had three goals: (1) quantify the degree of heavy metal accumulation in sparrows and determine the distributional patterns among study sites, (2) compare concentrations of metals found in this study to those found in studies performed prior to the 2009 international wastewater treatment plant upgrade, and (3) assess sparrow condition among sites with differing potential sources of contamination exposure. We examined six study sites that reflected different potential sources of contamination. Hematocrit values, body mass residuals, and leukocyte counts were used to assess sparrow condition. Cadmium, copper, mercury, nickel, and selenium exceeded background concentrations at some sites, but generally were lower than or similar to concentrations found in earlier studies performed prior to the 2009 international wastewater treatment plant upgrade. Concentrations were higher in recaptured birds in 2012 than in 2011 for 7 metals in feathers and 14 metals in blood, suggesting possible bioaccumulation. We found no cascading effects as a result of heavy metal exposure, but did find that heavy metal concentrations were reduced following the 2009 international wastewater treatment plant upgrade.

    The aim of the present study was to examine the parasite remains present in rodent coprolites collected from the archaeological site Cerro Casa de Piedra 7 (CCP7), located in the Perito Moreno National Park (47°57'S, 72°05'W), Santa Cruz Province, Argentina. Eight coprolites obtained from the layer 17, dated at 10,620 ± 40 to 9,390 ± 40 yr B.P., were examined for parasites. Feces were processed whole, rehydrated, homogenized, subjected to spontaneous sedimentation, and examined via light microscopy. Eggs of parasites were measured and photographed. Seven of 8 coprolites possessed 199 eggs of 2, probably new, species of nematodes, including 43 eggs of Heteroxynema sp. Hall, 1916 (Cavioxyura sp. Quentin, 1975) (Oxyurida, Heteroxynematidae), and 156 eggs of Trichuris sp. Roederer, 1761 (Trichinellida, Trichuridae). Heteroxynema sp. is cited for the first time from ancient material worldwide. The finding of Trichuris spp. in both rodents and other host samples from the area under study is indicative of the stability of the biological and environmental conditions for this nematode genus to establish in the Patagonian Early Holocene. The rodent host was assigned to an unknown species of Caviomorpha (Hystricognathi) that lived during the Pleistocenic transition in Patagonia.

    This project is part of a multidisciplinary effort aimed at understanding the impacts of climate variability and change on the ecological services provided by riparian ecosystems in semiarid watersheds of the southwestern United States. Valuing the environmental and recreational services provided by these ecosystems in the future requires a numerical simulation approach to estimate streamflow in ungauged tributaries as well as diffuse and direct recharge to groundwater basins. In this work, we utilize a distributed hydrologic model known as the TIN-based Real-time Integrated Basin Simulator (tRIBS) in the upper Santa Cruz and San Pedro basins with the goal of generating simulated hydrological fields that will be coupled to a riparian groundwater model. With the distributed model, we will evaluate a set of climate change and population scenarios to quantify future conditions in these two river systems and their impacts on flood peaks, recharge events and low flows. Here, we present a model confidence building exercise based on high performance computing (HPC) runs of the tRIBS model in both basins during the period of 1990-2000. Distributed model simulations utilize best-available data across the US-Mexico border on topography, land cover and soils obtained from analysis of remotely-sensed imagery and government databases. Meteorological forcing over the historical period is obtained from a combination of sparse ground networks and weather radar rainfall estimates. We then focus on a comparison between simulation runs using ground-based forcing to cases where the Weather Research Forecast (WRF) model is used to specify the historical conditions. Two spatial resolutions are considered from the WRF model fields - a coarse (35-km) and a downscaled (10- km) forcing. Comparisons will focus on the distribution of precipitation, soil moisture, runoff generation and recharge and assess the value of the WRF coarse and downscaled products. These results provide confidence in

    This paper describes a machine learning approach to detect sexually predatory behaviour in the massively multiplayer online game for children, MovieStarPlanet. The goal of this work is to take a chat log as an input and outputs its label as either the predatory category or the non......-predatory category. From the raw in-game chat logs provided by MovieStarPlanet, we first prepared three sub datasets via extensive preprocessing. Then, two machine learning algorithms, naive Bayes and Decision Tree, were employed to model the predatory behaviour using different feature sets. Our evaluation has...

    Increasingly scholars and researchers are being solicited by predatory open access journals seeking manuscript submissions and abusing the author-pays model by charging authors with publishing fees without any or proper peer review. Such questionable editorial practices are threatening the reputation and credibility of scholarly publishing. To date, no investigation has been conducted on this phenomenon in the field of rehabilitation. This study attempts to identify specific predatory journals operating in this field to quantify the phenomenon and its geographic distribution. Beall's List has been used to this end which, although not perfect, is a comprehensive and up-to-date report of predatory publishers. Of the 1113 publishers on the list, 59 journals were identified, for a total of 5610 published articles. The median number of articles published by each journal was 21, and the median amount of article processing charges was $499. Only 1 out of 59 journals was included in the Directory of Open Access Journals, whereas 7 (12%) were indexed by PubMed. Most of the publishers were based in India (36%) followed by the United States (25%) and Pakistan (5%), and 25% were without a verifiable address. The data indicate that the threat of predatory publishing in rehabilitation is real. Physiatrists, physiotherapists, researchers, and academics operating in this field are advised to use the tools available to recognize predatory practices before considering publishing in open access journals.

    Full Text Available Vertebrates with laterally placed eyes typically exhibit preferential eye use for ecological activities such as scanning for predators or prey. Processing visual information predominately through the left or right visual field has been associated with specialized function of the left and right brain. Lateralized vertebrates often share a general pattern of lateralized brain function at the population level, whereby the left hemisphere controls routine behaviors and the right hemisphere controls emergency responses. Recent studies have shown evidence of preferential eye use in some invertebrates, but whether the visual fields are predominately associated with specific ecological activities remains untested. We used the European common cuttlefish, Sepia officinalis, to investigate whether the visual field they use is the same, or different, during anti-predatory and predatory behavior. To test for lateralization of anti-predatory behavior, individual cuttlefish were placed in a new environment with opaque walls, thereby obliging them to choose which eye to orient away from the opaque wall to scan for potential predators (i.e. vigilant scanning. To test for lateralization of predatory behavior, individual cuttlefish were placed in the apex of an isosceles triangular arena and presented with two shrimp in opposite vertexes, thus requiring the cuttlefish to choose between attacking a prey item to the left or to the right of them. Cuttlefish were significantly more likely to favor the left visual field to scan for potential predators and the right visual field for prey attack. Moreover, individual cuttlefish that were leftward directed for vigilant scanning were predominately rightward directed for prey attack. Lateralized individuals also showed faster decision-making when presented with prey simultaneously. Cuttlefish appear to have opposite directions of lateralization for anti-predatory and predatory behavior, suggesting that there is functional

    An assessment of self-efficacy and social capital may have the potential to detect an effect of dynamic, complex and comprehensive collective actions in community-based health promotion. In 2003, a healthy village project was launched in Santa Cruz, Bolivia with technical assistance from the Japan International Cooperation Agency (JICA). The originally developed FORSA (Fortalecimiento de Redes de Salud) model accounted for participatory processes in which people could improve their health and well-being through individual behavioral changes and family/community-driven activities. This study aimed to examine the extent of self-efficacy and social capital obtained via project activities by a cross-sectional analysis. We randomly selected 340 subjects from the healthy village project site and 113 subjects from a control area. Both groups were interviewed using the same structured questionnaire. Self-efficacy was assessed with a General Self-Efficacy Scale (GSES), while social capital was measured as the frequency of formal group participation in community meetings during the past three months, perceived social solidarity, and general trust. The study results showed that the participants in the project site had higher self-efficacy and social capital compared to those in the control site. The number of times a subject participated in the health committee activities was positively associated with the self-efficacy scale. Regarding social capital, females and lower-educated people were more likely to have had more frequent participation in formal groups; males and higher-educated participants showed less formal group participation, but more generosity to contribute money for the community. The main perceived benefit of participation in formal group activities varied among individuals. The findings suggest that people in the healthy village project site have higher self-efficacy, especially those with active participation in the health committee activities. To recruit

    Starch gel electrophoresis was used for examining the transferrin gene locus (Tf) and two esterase gene loci (Est-1 and Est-D1) of a pirarucu (Arapaima gigas) population sample collected from Santa Cruz Lake, Tefé River, Amazonas, Brazil. The Tf locus was tentatively classified as being polymorphic, showing two double-banded patterns (Tf(12) and Tf(22)) of the three theoretically expected ones (Tf(11), Tf(12) and Tf(22)), presumably controlled by two co-dominant alleles, Tf(1) and Tf(2). The monotony detected in pirarucu Tf locus genotypes showing a very high proportion of the double-banded heterozygote pattern Tf(12) (95% of the sampled individuals) may indicate the possibility of their having come from representatives of the same brood begotten by a pair of fish, where a single-banded Tf(11) homozygote pattern male would have crossed with a single-banded Tf(22) homozygote pattern female, or vice versa. One zone of electrophoretic activity was detected in esterase, presumably controlled by a monomorphic Est-1 locus with the fixed allele Est-1(1) where all individuals showed the single-banded Est-1(11) homozygote pattern. Esterase-D also displayed one zone of electrophoretic activity, presumably controlled by a monomorphic Est-D1 locus with a fixed allele Est-D1(1) where all individuals revealed the single-banded Est-D1(11) genotype pattern. The monotony comprised by single-banded genotype patterns in both esterase systems tested may also indicate the possibility of the individuals from the sample examined having come from representatives of the same brood begotten by a pair of fish with both the male and female having the same genotypes.

Se emplearon técnicas macroscópicas y radiológicas para evaluar la prevalencia de caries, pérdida de dientes antemortem, abscesos y enfermedad periodontal. Asimismo, sólo de forma macroscópica, se relevó la prevalencia de cálculo dental y el grado de desgaste de la corona. Se observaron bajas prevalencias de caries, abscesos y pérdidas de piezas antemortem, altos grados de desgaste y moderadas frecuencias de cálculo dental. Se compararon estos resultados con aquellos obtenidos para otros grupos cazadores-recolectores. Los datos obtenidos en el lago Salitroso coinciden con lo observado para grupos con dietas altamente abrasivas y de bajo contenido de alimentos cariogénicos. Metodológicamente, la inclusión de técnicas radioscópicas permitió refinar el diagnóstico de abscesos, aunque mostró una baja sensibilidad para la detección de caries.

    It is well established that ageing handicaps the ability of prey to escape predators, yet surprisingly little is known about how ageing affects the ability of predators to catch prey. Research into long-lived predators has assumed that adults have uniform impacts on prey regardless of age. Here we use longitudinal data from repeated observations of individually-known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to demonstrate that adult predatory performance declines with age and that an increasing ratio of senescent individuals in the wolf population depresses the rate of prey offtake. Because this ratio fluctuates independently of population size, predatory senescence may cause wolf populations of equal size but different age structure to have different impacts on prey populations. These findings suggest that predatory senescence is an important, though overlooked, factor affecting predator-prey dynamics.

Moreno. Hacia fines de ese año, Florentino Ameghino, Secretario Subdirector del Museo de La Plata, dio a conocer dichos hallazgos describiendo sucintamente 122 taxones de los cuales 110 eran nuevas especies. Al poco tiempo, Florentino era exonerado del Museo, negándosele el acceso a las colecciones. No obstante, en 1889 Ameghino amplió sus descripciones y figuró 74 de los taxones de 1887. En 1891 Florentino Ameghino explicó que sus descripciones y figuras de 1889 se basaron en apuntes y croquis realizados antes de ser exonerado. Llamativamente, muchos de los ejemplares figurados se encuentran depositados en la Colección Naci onal Ameghino, alojada en el Museo Argentino de Ciencias Naturales "Bernardino Rivadavia". En 1980, basándose en este impensado destino de los fósiles, Larry Marshall concluyó que Florentino Ameghino se habría apropiado de una parte de la colección de 1887 y sobre ésta basó su obra de 1889. Las evidencias aquí presentadas avalan la apropiación de ejemplares propuesta por Marshall y brinda un marco de referencia para evaluar la conformación de las series tipo de las especies de 1887.

    Full Text Available Bacteria, which prey on other microorganisms, are commonly found in the environment. While some of these organisms act as solitary hunters, others band together in large consortia before they attack their prey. Anecdotal reports suggest that bacteria practicing such a wolfpack strategy utilize antibiotics as predatory weapons. Consistent with this hypothesis, genome sequencing revealed that these micropredators possess impressive capacities for natural product biosynthesis. Here, we will present the results from recent chemical investigations of this bacterial group, compare the biosynthetic potential with that of non-predatory bacteria and discuss the link between predation and secondary metabolism.

    Full Text Available As open access model of journal publication increases, predatory journals, which deceive scholars to publish journals in fake database websites and exploit them for publishing fee, is also increasing. There are two types of predatory journals. First, journal hijacking and cybersquatting generally create fake database website by mimicking authentic database website, thereby defrauding scholars for publication fee. Second, journal phishing use scam emails to steal scholars’ personal information. If scholars suffered damage from predatory journals, scholars can take either arbitral or judicial actions. Arbitral action follows arbitrational resolution process termed Uniform Domain-Name Dispute-Resolution Policy. Scholars can join Uniform Domain-Name Dispute-Resolution Policy proceeding with legal entity that has right to authentic database website, which will result in cancellation or transfer of fake database website. In contrast, scholars can take judicial action under Anticybersquatting Consumer Protection Act, which may help scholars to recover an actual monetary damage from predatory journals. Nonetheless, taking precaution to avoid predatory journals is the best course of action, rather than going through arduous cure procedures. Scholars may prevent predatory journals by carefully examining fake database website names or email addresses, or observing unreasonable number of published article issues in predatory journal websites.

    Intimate partner violence is widespread worldwide. While assumed to impact women's ability to use contraceptive methods, few data are available to support this claim. In this study, eight focus group discussions were conducted to guide questionnaire development and to provide contextual information. Participants were women who were currently using the pill and women who had used the pill previously. In addition, 300 women were interviewed who initiated oral contraceptive pill use between December 1995 and April 1996. Participants were interviewed 3-6 months later to investigate the role intimate partner violence played in covert pill use and pill discontinuation. Special study procedures for asking women questions about violence were employed. Nineteen per cent of the women interviewed were using the pill covertly. The odds of covert pill use were four times higher in El Alto and La Paz than in Santa Cruz. Women who used the pill covertly were more likely to have experienced method-related partner violence (OR = 21.27) than women whose partners knew of their pill use. One-third of the women had discontinued pill use at the time of the interview. In the final multivariate analysis, having experienced side-effects (OR = 2.37) was a significant predictor of pill discontinuation and method-related partner violence was marginally predictive (OR = 1.91; 95% CI 1.0-3.66). While efforts are ongoing to incorporate men into family planning programmes, some male partners oppose, and in some situations violently oppose, contraceptive use. The needs of women with these types of partners must not be overlooked.

    A wide range of insecticide resistance profiles has been reported across Bolivian domestic and sylvatic populations of Triatoma infestans (Klug, 1834) (Hemiptera, Reduviidae), including some with levels proven to be a threat for vector control. In this work, the insecticide profile of domestic T. infestans was studied with standardized toxicological bioassays, in an area that has not undergone consistent vector control. F1 first-instar nymphs hatched in laboratory from bugs captured in three communities from the Santa Cruz Department were evaluated with different insecticides. Moreover, the enzymatic activity of esterases and cytochrome P450 monooxygenases was measured in individual insects to evaluate the possible mechanism of metabolic resistance to pyrethroids. In addition, the DNA sequence of sodium channel gene (kdr) was screened for two point mutations associated with pyrethroid resistance previously reported in T. infestans.All populations showed reduced susceptibility to deltamethrin and α-cypermethrin, albeit the RR50 values varied significantly among them. Increased P450 monooxygenases and permethrate esterases suggest the contribution, as detoxifying mechanisms, to the observed resistance to deltamethrin in all studied populations. No individuals presented either mutation associated to resistance in the kdr gene. The level of susceptibility to α-cypermethrin, the insecticide used by the local vector control program, falls within an acceptable range to continue its use in these populations. However, the observed RR50 values evidence the possibility of selection for resistance to pyrethroids, especially to deltamethrin. Consequently, the use of pyrethroid insecticides should be closely monitored in these communities, which should be kept under entomological surveillance and sustained interventions. © The Authors 2016.

    Laboratory experiments revealed that the rocky shore gastropod, Nucella lamellosa (Gmelin), could discriminate between the effluents of predatory and non-predatory crabs. N. lamellosa turned away from seawater that had passed over the large predatory crab, Cancer productus Randall. This avoidance behavior was observed in snails from two localities that, based on differences in shell form, presumably experienced different levels of predation intensity. The scent of the non-predatory crabs Pugettia producta (Randall) and Lopholithodes mandtii Brandt had no effect on the turning behavior of snails from either site. Surprisingly, snails from both sites were attracted to the scent of a small shore crab, Hemigrapsus nudus (Dana), but moved at random in response to a common prey item Balanus glandula Darwin. These results suggest that N. lamellosa can assess from a distance the relative risks posed by different species of crabs, and respond appropriately. The unexpected attraction to H. nudus suggests that N. lamellosa may use this effluent to home in from a distance on potential refugia, because H. nudus are often associated with crevices and the undersides of boulders where N. lamellosa would be less vulnerable to larger predators.

    Nautical charts record seven locations off the coast of California labeled as 'Chemical Munitions Dumping Area, Disused' that together cover some 12,000 km2 of sea floor. However only one such chemical munitions site is officially documented and no record exists of any chemical munitions disposed of at other locations, thus creating confusion. We have executed a one day AUV mapping survey of a corner of one such site in the Santa Cruz Basin, south of Port Hueneme, to examine and investigate the debris field. The region is covered with soft sediment and the overlying water is very low in oxygen at ~10 μmol/kg. The processed 110 kHz sidescan data revealed some 754 targets in 25.6 km2 for an average of 29 targets per km2. This was followed by two ROV dives to investigate the targets identified. We found but one false positives among the over 40 targets visited, and found items ranging from two distinct lines of unmarked or labeled and now empty barrels, two target drones, and much miscellaneous debris including 4-packs of cat food cans and a large ships mast over 30m in length. There was zero evidence of chemical weapons materiel as expected given the lack of official records. Almost all of the targets were covered in dense and colorful assemblages of invertebrates: sponges, anemones, and crabs. Where barrels were sufficiently open for full visual inspection, the interior sea floor appeared to have become fully anoxic and was covered in white and yellow bacterial mat. The area chosen for our survey (centered at 33.76 deg N 119.56 deg W) was across the north western boundary of the marked site, and represents only ~ 10% percent of the designated area. Our expectation, that human nature would drive the disposal activities to the nearest corner of the chosen area rather than the center of the field appears to have been confirmed. Objects were found both within and outside of the boundary of the dump site. We have not surveyed the full marked area but there appears to be

    The differences on the uptake of P from the soil and fertilizer (triple superphosphate) and on nutrient use by two commercial tomato (Lycopersicum esculentum Will) varieties, Santa Clara and Santa Cruz Kada, were evaluated by 32 P technique. The experiment was carried out in two Brazilian soils, Dark Red Latosol from Piracicaba, Sao Paulo and calcareous Yellow Latosol from Irec Bahia, using pots with 2.5 kg soil. The radioisotope was added to the soil as KH2PO4 solution, with 3.7 MBq/pot. The dry matter weight, plant P content, L and A values were utilized for comparing the tomato varieties. There was a clear response to P fertilization. The Santa Cruz variety had higher dry matter weight and lower concentration than Santa Clara variety, but there was no difference on the total P taken up, indicating that the Santa Cruz variety

    The scientific community depends on high-quality peer-reviewed research, which is being polluted with pseudoscience published in fake journals that have exploited the open-access model. This "predatory publishing" has made its way into the field of dermatology. In a recent study, we identified and listed these journals. The "predatory rate" was calculated for 76 journals in order to rank the journals based on specific criteria associated with unethical publishing. Of the 76 journals, 89.5% were classified as predatory journals and the remaining as journals involved in predatory practices. The field of dermatology is not immune to predatory publishers. This study validates Beall's list as well as other previous studies. Strategies to a solution include spreading awareness throughout academic institutions and dermatology departments as well as avoiding publishers that are involved in predatory practices. However, some journals may be able to make necessary adjustments and become legitimate contributors to the field. © 2017 The International Society of Dermatology.

    The purpose of this study was to identify predatory journals in nursing, describe their characteristics and editorial standards, and document experiences of authors, peer reviewers, and editors affiliated with these journals. Using two sources that list predatory journals, the research team created a list of nursing journals. In Phase One, the team collected data on characteristics of predatory nursing journals such as types of articles published, article processing charge, and peer review process. In Phase Two, the team surveyed a sample of authors, reviewers, and editors to learn more about their experiences with their affiliated journals. Data from the review of predatory nursing journals were analyzed using descriptive statistics. Written comments were summarized and categorized. There were 140 predatory nursing journals from 75 publishers. Most journals were new, having been inaugurated in the past 1 to 2 years. One important finding was that many journals only published one or two volumes and then either ceased publishing or published fewer issues and articles after the first volume. Journal content varied widely, and some journals published content from dentistry and medicine, as well as nursing. Qualitative findings from the surveys confirmed previously published anecdotal evidence, including authors selecting journals based on spam emails and inability to halt publication of a manuscript, despite authors' requests to do so. Predatory journals exist in nursing and bring with them many of the "red flags" that have been noted in the literature, including lack of transparency about editorial processes and misleading information promoted on websites. The number of journals is high enough to warrant concern in the discipline about erosion of our scholarly literature. Nurses rely on the published literature to provide evidence for high-quality, safe care that promotes optimal patient outcomes. Research published in journals that do not adhere to the highest

    Predatory journals, or journals that charge an article processing charge (APC) to authors, yet do not have the hallmarks of legitimate scholarly journals such as peer review and editing, Editorial Boards, editorial offices, and other editorial standards, pose a number of new ethical issues in journal publishing. This paper discusses ethical issues around predatory journals and publishing in them. These issues include misrepresentation; lack of editorial and publishing standards and practices; academic deception; research and funding wasted; lack of archived content; and undermining confidence in research literature. It is important that the scholarly community, including authors, institutions, editors, and publishers, support the legitimate scholarly research enterprise, and avoid supporting predatory journals by not publishing in them, serving as their editors or on the Editorial Boards, or permitting faculty to knowingly publish in them without consequences.

  9. The impact of biotic/abiotic interfaces in mineral nutrient cycling: A study of soils of the Santa Cruz chronosequence, California

    Biotic/abiotic interactions between soil mineral nutrients and annual grassland vegetation are characterized for five soils in a marine terrace chronosequence near Santa Cruz, California. A Mediterranean climate, with wet winters and dry summers, controls the annual cycle of plant growth and litter decomposition, resulting in net above-ground productivities of 280-600gm -2yr -1. The biotic/abiotic (A/B) interface separates seasonally reversible nutrient gradients, reflecting biological cycling in the shallower soils, from downward chemical weathering gradients in the deeper soils. The A/B interface is pedologically defined by argillic clay horizons centered at soil depths of about one meter which intensify with soil age. Below these horizons, elevated solute Na/Ca, Mg/Ca and Sr/Ca ratios reflect plagioclase and smectite weathering along pore water flow paths. Above the A/B interface, lower cation ratios denote temporal variability due to seasonal plant nutrient uptake and litter leaching. Potassium and Ca exhibit no seasonal variability beneath the A/B interface, indicating closed nutrient cycling within the root zone, whereas Mg variability below the A/B interface denotes downward leakage resulting from higher inputs of marine aerosols and lower plant nutrient requirements.The fraction of a mineral nutrient annually cycled through the plants, compared to that lost from pore water discharge, is defined their respective fluxes F j,plants=q j,plants/(q j,plants+q j,discharge) with average values for K and Ca (F K,plants=0.99; F Ca,plants=0.93) much higher than for Mg and Na (F Mg,plants 0.64; F Na,plants=0.28). The discrimination against Rb and Sr by plants is described by fractionation factors (K Sr/Ca=0.86; K Rb/K=0.83) which are used in Rayleigh fractionation-mixing calculations to fit seasonal patterns in solute K and Ca cycling. K Rb/K and K24Mg/22Mg values (derived from isotope data in the literature) fall within fractionation envelopes bounded by inputs from

    We studied patterns of genetic diversity within and among 5 populations (318 individuals) of Galápagos marine iguanas (Amblyrhynchus cristatus) from the island Santa Fé. Populations were separated by distances of 0.2 to 9.9 km. We sequenced 1182 base pairs of the mitochondrial control region and screened 13 microsatellite loci for variability. We also added data from 5 populations (397 individuals) sampled on 4 neighboring islands (Santa Cruz, Floreana, Espanola, and San Cristobal). The 5 Santa Fé populations, revealed as genetically distinct from populations on other islands, present relatively low levels of genetic diversity, which are similar for both microsatellite (average observed heterozygosity from 0.7686 to 0.7773) and mitochondrial DNA (mtDNA) markers (haplotypic and nucleotide diversity from 0.587 to 0.728 and from 0.00079 to 0.00293, respectively), and comparable with those observed in similar-sized sampling sites on other islands. There was frequency-based evidence of genetic structure between northern and southern sites on Santa Fé (F(st) of 0.0027-0.0115 for microsatellite and 0.0447-0.2391 for mtDNA), but the 4 southern sites showed little differentiation. Most of the intra-island genetic variation was allocated within rather than between sites. There was no evidence of sex-biased dispersal or population substructuring due to lek-mating behavior, suggesting that these 2 observed behaviors are not strong enough to leave an evolutionary signal on genetic patterns in this species.

    1991-01-01

    The Ms 7.1 Loma Prieta earthquake of 18 October 1989 produced abundant ground ruptures in an 8 by 4 km area along Summit Road and Skyland Ridge in the Santa Cruz Mountains. Predominantly extensional fissures formed a left-stepping, crudely en echelon pattern along ridges of the hanging-wall block southwest of the San Andreas fault, about 12 km northwest of the epicenter. The fissures are subparallel to the San Andreas fault and appear to be controlled by bedding planes, faults, joints, and other weak zones in the underlying Tertiary sedimentary strata of the hanging-wall block. The pattern of extensional fissures is generally consistent with tectonic extension across the crest of the uplifted hanging-wall block. Also, many displacements in Laurel Creek canyon and along the San Andreas and Sargent faults are consistent with right-lateral reverse faulting inferred for the mainshock. Additional small tensile failures along the axis of the Laurel anticline may reflect growth of the fold during deep-seated compression. However, the larger ridge-top fissures commonly have displacements that are parallel to the north-northeast regional slope directions and appear inconsistent with east-northeast extension expected from this earthquake. Measured cumulative displacements across the ridge crests are at least 35 times larger than that predicted by the geodetically determined surface deformation. These fissures also occur in association with ubiquitous landslide complexes that were reactivated by the earthquake to produce the largest concentration of co-seismic slope failures in the epicentral region. The anomalously large displacements and the apparent slope control of the geometry and displacement of many co-seismic surface ruptures lead us to conclude that gravity is an important driving force in the formation of the ridge-top fissures. Shaking-induced gravitational spreading of ridges and downslope movement may account for 90¿ or more of the observed displacements on

    Radiometric surveys are a rapid tool to measure uranium (U), thorium (Th) and potassium (K) concentrations in rocks and are very useful in the exploration for radioactive minerals. The distribution of uranium in Jurassic volcanic rocks of the province of Santa Cruz is evaluated in this work using ground gamma-ray spectrometry and rock geochemistry in order to assess its potential to form uranium deposits. Five areas were selected, which had some previous data of high radiometric values and detailed geological information. Measurements were carried out with a portable gamma-ray spectrometer (Exploranium-GR 320®) in andesites, ignimbrites, rhyolites, silicified areas, ash-fall tuffs and lacustrine sediments corresponding to the Bahía Laura and to El Quemado complexes. The results were similar in the five surveyed areas: radiometric concentrations show good positive correlations with chemical composition of the studied rocks for both K and Th, and a relatively poorer correlation for U. Different processes such as magmatic differentiation, vapor phase crystallization, hydrothermal alteration and supergene alteration are reflected in the distribution of these elements. U concentrations increase in the more glassy rocks, in areas with hydrothermal silicification, and in fracture zones, features that should be considered in future surveys. The calkalkaline composition and arc-signatures of the Jurassic magmatism are not the most favorable for uranium enrichment and for concentration of significant mineralizations. However, the extensional tectonic setting; the occurrence of calderas with facies slightly enriched in U and Th, in addition to hydrothermal activity are positive factors for U exploration.

    Gravity anomalies, historical records of exploratory oil wells and oil seeps, new organic-geochemical results, and new stratigraphic and structural data indicate the presence of a concealed, oil-bearing sedimentary basin beneath a highly urbanized part of the Santa Clara Valley, Calif. A conspicuous isostatic-gravity low that extends about 35 km from Palo Alto southeastward to near Los Gatos reflects an asymmetric, northwest-trending sedimentary basin comprising low-density strata, principally of Miocene age, that rest on higher-density rocks of Mesozoic and Paleogene(?) age. Both gravity and well data show that the low-density rocks thin gradually to the northeast over a distance of about 10 km. The thickest (approx 4 km thick) accumulation of low-density material occurs along the basin's steep southwestern margin, which may be controlled by buried, northeast-dipping normal faults that were active during the Miocene. Movement along these hypothetical normal faults may been contemporaneous (approx 17–14 Ma) with sedimentation and local dacitic and basaltic volcanism, possibly in response to crustal extension related to passage of the northwestward-migrating Mendocino triple junction. During the Pliocene and Quaternary, the normal faults and Miocene strata were overridden by Mesozoic rocks, including the Franciscan Complex, along northeastward-vergent reverse and thrust faults of the Berrocal, Shannon, and Monte Vista Fault zones. Movement along these fault zones was accompanied by folding and tilting of strata as young as Quaternary and by uplift of the modern Santa Cruz Mountains; the fault zones remain seismically active. We attribute the Pliocene and Quaternary reverse and thrust faulting, folding, and uplift to compression caused by local San Andreas Fault tectonics and regional transpression along the Pacific-North American Plate boundary. Near the southwestern margin of the Santa Clara Valley, as many as 20 exploratory oil wells were drilled between 1891

    The aim of this study was to review and discuss predatory open access publishing in the context of nursing and midwifery and develop a set of guidelines that serve as a framework to help clinicians, educators and researchers avoid predatory publishers. Open access publishing is increasingly common across all academic disciplines. However, this publishing model is vulnerable to exploitation by predatory publishers, posing a threat to nursing and midwifery scholarship and practice. Guidelines are needed to help researchers recognize predatory journals and publishers and understand the negative consequences of publishing in them. Discussion paper. A literature search of BioMed Central, CINAHL, MEDLINE with Full Text and PubMed for terms related to predatory publishing, published in the period 2007-2017. Lack of awareness of the risks and pressure to publish in international journals, may result in nursing and midwifery researchers publishing their work in dubious open access journals. Caution should be taken prior to writing and submitting a paper, to avoid predatory publishers. The advantage of open access publishing is that it provides readers with access to peer-reviewed research as soon as it is published online. However, predatory publishers use deceptive methods to exploit open access publishing for their own profit. Clear guidelines are needed to help researchers navigate safely open access publishing. A deeper understanding of the risks of predatory publishing is needed. Clear guidelines should be followed by nursing and midwifery researchers seeking to publish their work in open access journals. © 2017 John Wiley & Sons Ltd.

    Epidemiologic studies have demonstrated that environmental lead exposure is associated with aggressive behavior in children; however, numerous confounding variables limit the ability of these studies to establish a causal relationship. The study of aggressive behavior using a validated animal model was used to test the hypothesis that there is a causal relationship between lead exposure and aggression in the absence of confounding variables. We studied the effects of lead exposure on a feline model of aggression: predatory (quiet biting) attack of an anesthetized rat. Five cats were stimulated with a precisely controlled electrical current via electrodes inserted into the lateral hypothalamus. The response measure was the predatory attack threshold current (i.e., the current required to elicit an attack response on 50% of the trials). Blocks of trials were administered in which predatory attack threshold currents were measured three times a week for a total of 6-10 weeks, including before, during, and after lead exposure. Lead was incorporated into cat food 'treats' at doses of 50-150 mg/kg/day. Two of the five cats received a second period of lead exposure. Blood lead concentrations were measured twice a week and were <1, 21-77, and <20 μg/dL prior to, during, and after lead exposure, respectively. The predatory attack threshold decreased significantly during initial lead exposure in three of five cats and increased after the cessation of lead exposure in four of the five cats (P<0.01). The predatory attack thresholds and blood lead concentrations for each cat were inversely correlated (r=-0.35 to -0.74). A random-effects mixed model demonstrated a significant (P=0.0019) negative association between threshold current and blood lead concentration. The data of this study demonstrate that lead exposure enhances predatory aggression in the cat and provide experimental support for a causal relationship between lead exposure and aggressive behavior in humans

    Predatory open access is a controversial publishing business model that exploits the open-access system by charging publication fees in the absence of transparent editorial services. The credibility of academic publishing is now seriously threatened by predatory journals, whose articles are accorded real citations and thus contaminate the genuine scientific records of legitimate journals. This is of particular concern for public health since clinical practice relies on the findings generated by scholarly articles. Aim of this study was to compile a list of predatory journals targeting the neurosciences and neurology disciplines and to analyze the magnitude and geographical distribution of the phenomenon in these fields. Eighty-seven predatory journals operate in neurosciences and 101 in neurology, for a total of 2404 and 3134 articles issued, respectively. Publication fees range 521-637 USD, much less than those charged by genuine open-access journals. The country of origin of 26.0-37.0% of the publishers was impossible to determine due to poor websites or provision of vague or non-credible locations. Of the rest 35.3-42.0% reported their headquarters in the USA, 19.0-39.2% in India, 3.0-9.8% in other countries. Although calling themselves "open-access", none of the journals retrieved was listed in the Directory of Open Access Journals. However, 14.9-24.7% of them were found to be indexed in PubMed and PubMed Central, which raises concerns on the criteria for inclusion of journals and publishers imposed by these popular databases. Scholars in the neurosciences are advised to use all the available tools to recognize predatory practices and avoid the downsides of predatory journals. Copyright © 2017 IBRO.

    Open access publishing enables scholarship to be openly accessible to everyone, which has countless benefits. However, the open access movement has opened the door for "predatory publishers" to take advantage of researchers surviving in this publish or perish academic landscape. Predatory journals are becoming increasingly common. Nursing researchers, instructors, and students need to be made aware of the dangers of predatory journals, and they need to know how to identify them. While there are blacklists and whitelists that can be used to aid in decision-making, it is critical to note that these lists can never be entirely up to date. This article incorporates a literature review which provides insights into newer trends in predatory and unethical publishing, including "journal hijacking" and "bogus impact factors". Extensive criteria for assessing emerging or unknown journals is compiled to aid researchers, students, educators, and the public in evaluating open access publications.

    Science.gov (United States)

    Kratochvíl, Jiří; Plch, Lukáš

    Authors who publish in scientific or scholarly journals today face the risk of publishing in so-called predatory journals. These journals exploit the noble idea of the Open Access movement, whose goal is to make the latest scientific findings available for free. Predatory journals, unlike the reputable ones working on an Open Access basis, neglect the review process and publish low-quality submissions. The basic attributes of predatory journals are a very quick review process or even none at all, failure to be transparent about author fees for publishing an article, misleading potential authors by imitating the names of well-established journals, and false information on indexing in renowned databases or assigned impact factor. Some preventive measures against publishing in predatory journals or drawing information from them are: a thorough credibility check of the journals webpages, verification of the journals indexing on Bealls List and in the following databases: Web of Science Core Collection, Scopus, ERIH PLUS and DOAJ. Asking other scientists or scholars about their experience with a given journal can also be helpful. Without these necessary steps authors face an increased risk of publishing in a journal of poor quality, which will prevent them from obtaining Research and Development Council points (awarded based on the Information Register of Research & Development results); even more importantly, it may damage their reputation as well as the good name of their home institution in the professional community.Key words: academic writing - medical journals - Open Access - predatory journals - predatory publishers - scientific publications.

  11. Chemical weathering of a marine terrace chronosequence, Santa Cruz, California I: Interpreting rates and controls based on soil concentration-depth profiles

    The spatial and temporal changes in element and mineral concentrations in regolith profiles in a chronosequence developed on marine terraces along coastal California are interpreted in terms of chemical weathering rates and processes. In regoliths up to 15 m deep and 226 kyrs old, quartz-normalized mass transfer coefficients indicate non-stoichiometric preferential release of Sr > Ca > Na from plagioclase along with lesser amounts of K, Rb and Ba derived from K-feldspar. Smectite weathering results in the loss of Mg and concurrent incorporation of Al and Fe into secondary kaolinite and Fe-oxides in shallow argillic horizons. Elemental losses from weathering of the Santa Cruz terraces fall within the range of those for other marine terraces along the Pacific Coast of North America. Residual amounts of plagioclase and K-feldspar decrease with terrace depth and increasing age. The gradient of the weathering profile bs is defined by the ratio of the weathering rate, R to the velocity at which the profile penetrates into the protolith. A spreadsheet calculator further refines profile geometries, demonstrating that the non-linear regions at low residual feldspar concentrations at shallow depth are dominated by exponential changes in mineral surface-to-volume ratios and at high residual feldspar concentrations, at greater depth, by the approach to thermodynamic saturation. These parameters are of secondary importance to the fluid flux qh, which in thermodynamically saturated pore water, controls the weathering velocity and mineral losses from the profiles. Long-term fluid fluxes required to reproduce the feldspar weathering profiles are in agreement with contemporary values based on solute Cl balances (qh = 0.025-0.17 m yr-1). During saturation-controlled and solute-limited weathering, the greater loss of plagioclase relative to K-feldspar is dependent on the large difference in their respective solubilities instead of the small difference between their respective

Os resultados obtidos permitiram identificar que em uma situação na qual qualquer um destes efluentes fosse lançado neste corpo receptor, mesmo que de forma isolada, resultaria em sérios prejuízos ambientais decorrentes de efeitos agudos e crônicos. A baixa vazão deste recurso hídrico reduz por conseqüência a sua capacidade de suportar impactos deste tipo, denunciando uma completa incompatibilidade entre as atividades geradoras destes resíduos e o ecossistema local. Assim, a alternativa para compatibilizar estes fatores passa pela otimização de processos industriais e a implantação de políticas voltadas ao reuso de águas no processo, de forma a minimizar o volume de efluente gerado e a sua ecotoxicidade.

    1. Large body size hinders locomotor performance in ways that may lead to trade-offs in predator foraging ability that limit the net predatory benefit of larger size. For example, size-related improvements in handling prey may come at the expense of pursuing prey and thus negate any enhancement in overall predatory performance due to increasing size. 2. This hypothesis was tested with longitudinal data from repeated observations of 94 individually known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park, USA. Wolf size was estimated from an individually based sex-specific growth model derived from body mass measurements of 304 wolves. 3. Larger size granted individual wolves a net predatory advantage despite substantial variation in its effect on the performance of different predatory tasks; larger size improved performance of a strength-related task (grappling and subduing elk) but failed to improve performance of a locomotor-related task (selecting an elk from a group) for wolves > 39 kg. 4. Sexual dimorphism in wolf size also explained why males outperformed females in each of the three tasks considered (attacking, selecting, and killing). 5. These findings support the generalization that bigger predators are overall better hunters, but they also indicate that increasing size ultimately limits elements of predatory behaviour that require superior locomotor performance. We argue that this could potentially narrow the dietary niche of larger carnivores as well as limit the evolution of larger size if prey are substantially more difficult to pursue than to handle.

  19. Predatory Publishing: An Emerging Threat to the Medical Literature.

    Science.gov (United States)

    Harvey, H Benjamin; Weinstein, Debra F

    2017-02-01

    The quality of medical literature is increasingly threatened by irresponsible publishing, leading to rising retraction rates, irreproducible results, and a flood of inconsequential publications that distract readers from more meaningful scholarship. "Predatory publishers" offer rapid publication with loose peer review, exploiting a system in which faculty seek longer bibliographies to achieve academic promotion. In this Commentary, the authors highlight some of the evidence that this problem exists and suggest actions to address it. Recommendations for protecting the medical literature include preventing predatory journals from being indexed by the National Library of Medicine; encouraging academic promotions committees to ensure that they prioritize value over volume of publications and that faculty understand that priority; excluding publications from predatory journals on curricula vitae and requiring that retractions are included; developing sanctions for repeated retractions or duplicate publications; and convening an expert panel to better elucidate this problem and determine strategies to combat it.

  1. Predatory behavior of the land flatworm Notogynaphallia abundans (Platyhelminthes: Tricladida

    Maria E. T. Prasniski

    Full Text Available Land flatworms are carnivorous, mainly predators. However, knowledge on their predatory behavior and prey preference is very scarce. This paucity of data is a limiting factor in the study of their biology and organismal ecology, resulting in a very difficult task to breed them in the laboratory for prolonged periods if prey preference and predation frequency are unknown. We investigated the predatory behavior of Notogynaphallia abundans (Graff, 1899, Geoplaninae, based on laboratory experiments. In order to determine its predatory choices, we offered mollusks, earthworms, arthropods, and other land flatworms. Only land isopods were accepted, with an average consumption of 3.4 individuals per week. Linear regression showed a positive relationship between the number of consumed isopods and the increase/decrease in body mass. Consumption resulting in an increase in body mass was ca. four isopods per week. Predatory behavior, with a mean time-span of 28 min 45 s ± 15 min 47 s, includes encounter and capture of prey, immobilization, handling and feeding. Variation in the duration of this activity in N. abundans is clearly due to variations in the time necessary for transferring the prey from either the anterior or posterior thirds of the body to the mouth, as well as for external digestion and ingestion. In order to capture very active and fast-moving animals such as land isopods, N. abundans employs various strategies, using either the anterior or the posterior body regions to press the prey against the ground or against its own body, thus allowing it to deal with various responses by the prey, and thereby maximizing predatory success. Similar to other flatworms, both physical holding and entrapment in a mucous secretion are of fundamental importance for prey-immobilization. The different strategies employed by land flatworms in their predatory behavior are discussed, and behavioral plasticity in the capture and immobilization of prey in different

    The purpose of this report is to inform and warn academics about practices used by cybercriminals who seek to profit from unwary scholars and undermine the industry of science. This report describes the signs, symptoms, characteristics, and consequences of predatory publishing and related forms of consumer fraud. Methods to curb these cybercrimes include educating scholars and students about tactics used by predatory publishers; institutional changes in how faculty are evaluated using publications; soliciting cooperation from the industries that support academic publishing and indexing to curb incorporation of illegitimate journals; and taking an offensive position by reporting these consumer fraud crimes to the authorities. Over and above the problem of publishing good science in fraudulent journals, disseminating and citing poor-quality research threaten the credibility of science and of nursing. © 2018 John Wiley & Sons Australia, Ltd.

    As a result of ongoing changes in climate, hydrologic and ecologic effects are being seen across the western United States. A regional study of how climate change affects water resources and habitats in the San Francisco Bay area relied on historical climate data and future projections of climate, which were downscaled to fine spatial scales for application to a regional water-balance model. Changes in climate, potential evapotranspiration, recharge, runoff, and climatic water deficit were modeled for the Bay Area. In addition, detailed studies in the Russian River Valley and Santa Cruz Mountains, which are on the northern and southern extremes of the Bay Area, respectively, were carried out in collaboration with local water agencies. Resource managers depend on science-based projections to inform planning exercises that result in competent adaptation to ongoing and future changes in water supply and environmental conditions. Results indicated large spatial variability in climate change and the hydrologic response across the region; although there is warming under all projections, potential change in precipitation by the end of the 21st century differed according to model. Hydrologic models predicted reduced early and late wet season runoff for the end of the century for both wetter and drier future climate projections, which could result in an extended dry season. In fact, summers are projected to be longer and drier in the future than in the past regardless of precipitation trends. While water supply could be subject to increased variability (that is, reduced reliability) due to greater variability in precipitation, water demand is likely to steadily increase because of increased evapotranspiration rates and climatic water deficit during the extended summers. Extended dry season conditions and the potential for drought, combined with unprecedented increases in precipitation, could serve as additional stressors on water quality and habitat.

    2015-01-01

    Authors face many choices when selecting a journal for publication. Prospective authors, especially trainees, may be unaware of "predatory" online journals or how to differentiate them from legitimate journals. In this study, we assessed awareness of open-access and predatory journals among prospective authors attending scientific writing workshops; our long-term goal was to inform educational goals for the workshops. We surveyed participants of writing workshops at veterinary and medical schools and an international conference over a 1-year period. The survey included 14 statements for respondents to indicate agreement level on a Likert-like scale and four questions on awareness of resources about predatory journals; respondents also defined "predatory journal." A total of 145 participants completed the survey: 106 (73.1%) from veterinary schools and 86 (59.3%) graduate students or residents. Fewer faculty (vs trainees) agreed that open access was an important factor in deciding where to publish; faculty and postdoctoral researchers were more likely to expect to pay more to publish in an open-access journal. Most respondents (120/145, 82.7%) agreed/strongly agreed that the decision to accept a manuscript should not be influenced by publication charges, but 50% (56/112) indicated that they "didn't know" how publishing costs were supported. Of the 142 respondents who answered, 33 (23.0%) indicated awareness of the term "predatory journal"; 34 (23.9%) were aware of the Directory of Open Access Journals; 24 (16.9%) were aware of the Science "sting" article about predatory journals; and 7 (4.8%) were aware of Beall's list. Most (93/144, 64.5%) definitions of predatory journals described poor but not predatory journal practices, and some respondents misunderstood the term completely.

    Integrated pest management (IPM) is widely practiced in commercial oil palm agriculture.This management system is intended to minimize the number of attacks by pest insects such as bagworms on crops,as well as curb economic loss with less dependency on chemical pesticides.One practice in IPM is the use of biological control agents such as predatory insects.In this study,we assessed the response of predatory natural enemies to pest outbreak and water stress,and document the habitat associations of potential pest predators.The abundances of 2 predatory insect species,namely Sycanus dichotomus and Cosmolestes picticeps (Hemiptera:Reduviidae),were compared bagworm outbreak sites and nonoutbreak sites within oil palm plantations.We also examined habitat characteristics that influence the abundances of both predatory species.We found that the abundance of C.picticeps was significantly higher in bagworm outbreak sites than in nonoutbreak sites.There were no significant differences in the abundance of S.dichotomus among outbreak and non-outbreak sites.Both species responded negatively to water stress in oil palm plantations.Concerning the relationship between predatory insect abundance and in situ habitat quality characteristics,our models explained 46.36% of variation for C.picticeps and 23.17% of variation for S.dichotomus.Both species of predatory insects thrived from the planting of multiple beneficial plants in oil palm plantations.The results suggest that C.picticeps can be used as a biological agent to control bagworm populations in oil palm plantations,but S.dichotomus has no or little potential for such ecosystem service.

    The Internet has transformed scholarly publishing, most notably, by the introduction of open access publishing. Recently, there has been a rise of online journals characterized as 'predatory', which actively solicit manuscripts and charge publications fees without providing robust peer review and editorial services. We carried out a cross-sectional comparison of characteristics of potential predatory, legitimate open access, and legitimate subscription-based biomedical journals. On July 10, 2014, scholarly journals from each of the following groups were identified - potential predatory journals (source: Beall's List), presumed legitimate, fully open access journals (source: PubMed Central), and presumed legitimate subscription-based (including hybrid) journals (source: Abridged Index Medicus). MEDLINE journal inclusion criteria were used to screen and identify biomedical journals from within the potential predatory journals group. One hundred journals from each group were randomly selected. Journal characteristics (e.g., website integrity, look and feel, editors and staff, editorial/peer review process, instructions to authors, publication model, copyright and licensing, journal location, and contact) were collected by one assessor and verified by a second. Summary statistics were calculated. Ninety-three predatory journals, 99 open access, and 100 subscription-based journals were analyzed; exclusions were due to website unavailability. Many more predatory journals' homepages contained spelling errors (61/93, 66%) and distorted or potentially unauthorized images (59/93, 63%) compared to open access journals (6/99, 6% and 5/99, 5%, respectively) and subscription-based journals (3/100, 3% and 1/100, 1%, respectively). Thirty-one (33%) predatory journals promoted a bogus impact metric - the Index Copernicus Value - versus three (3%) open access journals and no subscription-based journals. Nearly three quarters (n = 66, 73%) of predatory journals had editors or

    This paper proposes a new particle swarm optimization (PSO) strategy namely, anti-predatory particle swarm optimization (APSO) to solve nonconvex economic dispatch problems. In the classical PSO, the movement of a particle (bird) is governed by three behaviors: inertial, cognitive and social. The cognitive and social behaviors are the components of the foraging activity, which help the swarm of birds to locate food. Another activity that is observed in birds is the anti-predatory nature, which helps the swarm to escape from the predators. In this work, the anti-predatory activity is modeled and embedded in the classical PSO to form APSO. This inclusion enhances the exploration capability of the swarm. To validate the proposed APSO model, it is applied to two test systems having nonconvex solution spaces. Satisfactory results are obtained when compared with previous approaches. (author)

    Epidemiologic studies have demonstrated that environmental lead exposure is associated with aggressive behavior in children; however, numerous confounding variables limit the ability of these studies to establish a causal relationship. The study of aggressive behavior using a validated animal model was used to test the hypothesis that there is a causal relationship between lead exposure and aggression in the absence of confounding variables. We studied the effects of lead exposure on a feline model of aggression: predatory (quiet biting) attack of an anesthetized rat. Five cats were stimulated with a precisely controlled electrical current via electrodes inserted into the lateral hypothalamus. The response measure was the predatory attack threshold current (i.e., the current required to elicit an attack response on 50% of the trials). Blocks of trials were administered in which predatory attack threshold currents were measured three times a week for a total of 6-10 weeks, including before, during, and after lead exposure. Lead was incorporated into cat food "treats" at doses of 50-150 mg/kg/day. Two of the five cats received a second period of lead exposure. Blood lead concentrations were measured twice a week and were cats and increased after the cessation of lead exposure in four of the five cats (Pcat were inversely correlated (r=-0.35 to -0.74). A random-effects mixed model demonstrated a significant (P=0.0019) negative association between threshold current and blood lead concentration. The data of this study demonstrate that lead exposure enhances predatory aggression in the cat and provide experimental support for a causal relationship between lead exposure and aggressive behavior in humans.

    Full Text Available Authors face many choices when selecting a journal for publication. Prospective authors, especially trainees, may be unaware of predatory online journals or how to differentiate them from legitimate journals. In this study we assessed awareness of open-access and predatory journals among prospective authors attending scientific writing workshops; our long-term goal was to inform educational goals for the workshops. We surveyed participants of writing workshops at veterinary and medical schools and an international conference over a 1-year period. The survey included 14 statements for respondents to indicate agreement level on a Likert-like scale and four questions on awareness of resources about predatory journals; respondents also defined predatory journal. A total of 145 participants completed the survey: 106 (73.1% from veterinary schools and 86 (59.3% graduate students or residents. Fewer faculty (vs trainees agreed that open access was an important factor in deciding where to publish; faculty and postdoctoral researchers were more likely to expect to pay more to publish in an open-access journal. Most respondents (120/145, 82.7% agreed/strongly agreed that the decision to accept a manuscript should not be influenced by publication charges, but 50% (56/112 indicated they didn’t know how publishing costs were supported. Of the 142 respondents who answered, 33 (23.0% indicated awareness of the term predatory journal; 34 (23.9% were aware of the Directory of Open Access Journals; 24 (16.9% were aware of the Science sting article about predatory journals; and 7 (4.8% were aware of Beall’s list.

  2. The distribution and abundance of reef-associated predatory fishes on the Great Barrier Reef

    Predatory fishes are important components of coral-reef ecosystems of the Great Barrier Reef (GBR) through both the ecological functions they perform and their high value to recreational and commercial fisheries, estimated at 30 million in 2014. However, management of GBR predatory fish populations is hampered by a lack of knowledge of their distribution and abundance, aside from that of the highly targeted coral trout ( Plectropomus spp. and Variola spp.). Furthermore, there is little information on how these fishes respond to environmental stressors such as coral bleaching, outbreaks of coral-feeding starfishes ( Acanthaster planci) and storms, which limits adaptive management of their populations as the frequency or severity of such natural disturbances increases under climate change. Here, we document the distribution and abundance of 48 species of reef-associated predatory fishes and assess their vulnerability to a range of natural disturbances. There were clear differences in predatory fish assemblages across the continental shelf, but many species were widespread, with few species restricted to either inshore or offshore waters. There was weak latitudinal structure with only a few species restricted to either the northern or southern GBR. On the whole, predatory fishes were surprisingly resistant to the effects of disturbance, with few clear changes in abundance or species richness following 66 documented disturbances of varying magnitudes.

    The issue of predatory journals has become increasingly more prevalent over the past decade, as the open-access model of publishing has gained prominence. Although the open-access model is well intentioned to increase accessibility of biomedical research, it is vulnerable to exploitation by those looking to corrupt medical academia and circumvent ethics and research standards. Predatory journals will achieve publication by either soliciting unsuspecting researchers who have legitimate research but fall victim to these predators or researchers looking to quickly publish their research without a thorough review process. Some features of predatory journals are a quick non-peer-review process, falsely listing or exaggerating the credibility of editorial board members, and either lack of or falsification of institutional affiliations and database listings. These predatory journals are a serious threat to the integrity of medical research, as they will infect the available literature with unsubstantiated articles, and allow low-quality research. A number of steps can be taken to prevent the spread and increase awareness of predatory publishers, and these must be done to maintain the integrity of medical academia. Clin.

    Predatory mites of the Phytoseiidae family are considered one of the most important groups of natural enemies used in biological control. The behavioral patterns of arthropods can differ greatly daily and seasonally; however, there is a lack of literature related to Phytoseiidae diel and seasonal predation patterns. The predatory activity of three phytoseiid species (two Tetranychidae-specialists, Phytoseiulus persimilis and Neoseiulus californicus, and one omnivore, Euseius stipulatus) that occur naturally in Spanish citrus orchards was observed under laboratory conditions in winter and summer. The temperature and photoperiod of the climatic chamber where the mites were reared did not change during the experiment. Our study demonstrates that phytoseiids can exhibit diel and seasonal predatory patterns when feeding on Tetranychus urticae (Acari: Tetranychidae). Neoseiulus californicus was revealed to be a nocturnal predator in summer but diurnal in winter. In contrast, P. persimilis activity was maximal during the daytime, and E. stipulatus showed no clear daily predation patterns. The predatory patterns described in this study should be taken into account when designing laboratory studies and also in field samplings, especially when applying molecular techniques to unveil trophic relationships. © 2017 Institute of Zoology, Chinese Academy of Sciences.

  12. Psychological stress on female mice diminishes the developmental potential of oocytes: a study using the predatory stress model.

    Directory of Open Access Journals (Sweden)

    Yu-Xiang Liu

    Full Text Available Although the predatory stress experimental protocol is considered more psychological than the restraint protocol, it has rarely been used to study the effect of psychological stress on reproduction. Few studies exist on the direct effect of psychological stress to a female on developmental competence of her oocytes, and the direct effect of predatory maternal stress on oocytes has not been reported. In this study, a predatory stress system was first established for mice with cats as predators. Beginning 24 h after injection of equine chorionic gonadotropin, female mice were subjected to predatory stress for 24 h. Evaluation of mouse responses showed that the predatory stress system that we established increased anxiety-like behaviors and plasma cortisol concentrations significantly and continuously while not affecting food and water intake of the mice. In vitro experiments showed that whereas oocyte maturation and Sr(2+ activation or fertilization were unaffected by maternal predatory stress, rate of blastocyst formation and number of cells per blastocyst decreased significantly in stressed mice compared to non-stressed controls. In vivo embryo development indicated that both the number of blastocysts recovered per donor mouse and the average number of young per recipient after embryo transfer of blastocysts with similar cell counts were significantly lower in stressed than in unstressed donor mice. It is concluded that the predatory stress system we established was both effective and durative to induce mouse stress responses. Furthermore, predatory stress applied during the oocyte pre-maturation stage significantly impaired oocyte developmental potential while exerting no measurable impact on nuclear maturation, suggesting that cytoplasmic maturation of mouse oocytes was more vulnerable to maternal stress than nuclear maturation.

  19. The role of methyl salicylate in prey searching behavior of the predatory mite phytoseiulus persimilis.

    De Boer, Jetske G; Dicke, Marcel

    2004-02-01

    Many carnivorous arthropods use herbivore-induced plant volatiles to locate their prey. These plant volatiles are blends of up to hundreds of compounds. It is often unknown which compounds in such a complex volatile blend represent the signal to the foraging carnivore. We studied the role of methyl salicylate (MeSA) as part of the volatile blend in the foraging behavior of the predatory mite Phytoseiulus persimilis by using a Y-tube olfactometer. MeSA is one of the compounds released by lima bean, infested with Tetranychus urticae--a prey species of the predatory mite. MeSA attracted satiated predatory mites in a dose-dependent way with optimum attraction at a dose of 0.2 microg. Predatory mites did not discriminate between a prey-induced lima bean volatile blend (that contains MeSA) and a prey-induced volatile blend to which an extra amount of synthetic MeSA had been added. However, they preferred a MeSA-containing volatile blend (induced by T. urticae) to an otherwise similar but MeSA-free blend (induced by jasmonic acid). Adding synthetic MeSA to the MeSA-free blend significantly increased the mites' choice for this odor, suggesting an important role for MeSA. This study is a new step toward unraveling the role of herbivore-induced plant volatiles in the foraging behavior of predatory arthropods.

    1998-01-01

    There appear to be no brain imaging studies investigating which brain mechanisms subserve affective, impulsive violence versus planned, predatory violence. It was hypothesized that affectively violent offenders would have lower prefrontal activity, higher subcortical activity, and reduced prefrontal/subcortical ratios relative to controls, while predatory violent offenders would show relatively normal brain functioning. Glucose metabolism was assessed using positron emission tomography in 41 comparisons, 15 predatory murderers, and nine affective murderers in left and right hemisphere prefrontal (medial and lateral) and subcortical (amygdala, midbrain, hippocampus, and thalamus) regions. Affective murderers relative to comparisons had lower left and right prefrontal functioning, higher right hemisphere subcortical functioning, and lower right hemisphere prefrontal/subcortical ratios. In contrast, predatory murderers had prefrontal functioning that was more equivalent to comparisons, while also having excessively high right subcortical activity. Results support the hypothesis that emotional, unplanned impulsive murderers are less able to regulate and control aggressive impulses generated from subcortical structures due to deficient prefrontal regulation. It is hypothesized that excessive subcortical activity predisposes to aggressive behaviour, but that while predatory murderers have sufficiently good prefrontal functioning to regulate these aggressive impulses, the affective murderers lack such prefrontal control over emotion regulation.

    Full Text Available In this paper we analyse the period in which the first foundations of the Brotherhoods and Fraternities of the True Cross took place in the Basque Country and assess the importance that the cult of the Cross had in this region. In addition, we examine carefully and systematically the evident relations between the fraternity of the True Cross in Bilbao and the fraternity of the True Cross in Vitoria, for whose foundation in 1538 there is documented evidence. This study shows that the statutes of the fraternity of the True Cross in the town of Vitoria were taken into account by those who decided to set up the same fraternity in the town of Bilbao in the middle of the sixteenth century.En este artículo se analiza y valora el período en que se produjeron en el País Vasco las primeras fundaciones de las Hermandades y Cofradías de la Vera Cruz, así como la importancia que tuvo el culto a la Cruz en este territorio.

  12. Serotonin Drives Predatory Feeding Behavior via Synchronous Feeding Rhythms in the Nematode Pristionchus pacificus

    Directory of Open Access Journals (Sweden)

    Misako Okumura

    2017-11-01

    Full Text Available Feeding behaviors in a wide range of animals are regulated by the neurotransmitter serotonin, although the exact neural circuits and associated mechanism are often unknown. The nematode Pristionchus pacificus can kill other nematodes by opening prey cuticles with movable teeth. Previous studies showed that exogenous serotonin treatment induces a predatory-like tooth movement and slower pharyngeal pumping in the absence of prey; however, physiological functions of serotonin during predation and other behaviors in P. pacificus remained completely unknown. Here, we investigate the roles of serotonin by generating mutations in Ppa-tph-1 and Ppa-bas-1, two key serotonin biosynthesis enzymes, and by genetic ablation of pharynx-associated serotonergic neurons. Mutations in Ppa-tph-1 reduced the pharyngeal pumping rate during bacterial feeding compared with wild-type. Moreover, the loss of serotonin or a subset of serotonergic neurons decreased the success of predation, but did not abolish the predatory feeding behavior completely. Detailed analysis using a high-speed camera revealed that the elimination of serotonin or the serotonergic neurons disrupted the timing and coordination of predatory tooth movement and pharyngeal pumping. This loss of synchrony significantly reduced the efficiency of successful predation events. These results suggest that serotonin has a conserved role in bacterial feeding and in addition drives the feeding rhythm of predatory behavior in Pristionchus.

    Zika virus (ZIKV), was widely reported in Latin America and has been associated with neuropathologies, as microcephaly, but only few seroprevalence studies have been published to date. Our objective was to determine the seroprevalence amongst Bolivian blood donors and estimate the future potential circulation of the virus. A ZIKV seroprevalence study was conducted between December 2016 and April 2017 in 814 asymptomatic Bolivian volunteer blood donors residing in various eco-environments corresponding to contrasting entomological activities. It was based on detection of IgG to ZIKV using NS1 ELISA screening, followed by a seroneutralisation test in case of positive or equivocal ELISA result. Analysis revealed that ZIKV circulation occurred in tropical areas (Beni: 39%; Santa Cruz de la Sierra: 21.5%) but not in highlands (~0% in Cochabamba, La Paz, Tarija). It was modulated by Aedes aegypti activity and the virus spread was not limited by previous immunity to dengue. Cases were geo-localised in a wide range of urban areas in Santa Cruz and Trinidad. No differences in seroprevalence related to gender or age-groups could be identified. It is concluded that ZIKV has been intensely circulating in the Beni region and has still a significant potential for propagating in the area of Santa Cruz.

    We approach the problem of "predatory" journals and publishers from the perspective of small scientific communities and small journals that may sometimes be perceived as "predatory". Among other characteristics of "predatory" journals two most relevant are their business model and the quality of the editorial work. We analysed 444 Croatian open access (OA) journals in the Hrčak (portal of Croatian scientific journals) digital journal repository for the presence of article processing charges as a business model and the transparency of editorial policies. The majority of journals do not charge authors or require submission or article processing charges, which clearly distinguishes them from "predatory" journals. Almost all Hrčak OA journals have publicly available information on editorial boards, including full names and affiliations, and detailed contact information for the editorial office at the Hrčak website. The journal names are unique and cannot be easily confused with another journal or intend to mislead about the journal's origin. While most journals provide information on peer review process, many do not provide guidelines for reviewers or other editorial and publication ethics standards. In order to clearly differentiate themselves from predatory journals, it is not enough for journals from small research communities to operate on non-commercial bases, but also to have transparent editorial policies.

    The spider mite, Tetranychus urticae, is the major strawberry pest in Brazil. The main strategies for its control comprise synthetic acaricides and predatory mites. The recent register of a commercial formula of azadirachtin (Azamax(®) 12 g L(-1) ) can be viable for control of T. urticae. In this work, the effects of azadirachtin on T. urticae and its compatibility with predatory mites Neoseiulus californicus and Phytoseiulus macropilis in the strawberry crop were evaluated. Azadirachtin was efficient against T. urticae, with a mortality rate similar to that of abamectin. In addition, the azadirachtin showed lower biological persistence (7 days) than abamectin (21 days). Azadirachtin did not cause significant mortality of adult predatory mites (N. californicus and P. macropilis), but it did reduce fecundity by 50%. However, egg viability of the azadirachtin treatments was similar to that of the control (>80% viability). The use of azadirachtin and predatory mites is a valuable tool for controlling T. urticae in strawberry crop. Azadirachtin provided effective control of T. urticae and is compatible with the predatory mites N. californicus and P. macropilis. It is an excellent tool to be incorporated into integrated pest management for strawberry crop in Brazil. Copyright © 2012 Society of Chemical Industry.

  3. Initiation of chromosomal replication in predatory bacterium Bdellovibrio bacteriovorus

    Directory of Open Access Journals (Sweden)

    Lukasz Makowski

    2016-11-01

    Full Text Available Bdellovibrio bacteriovorus is a small Gram-negative predatory bacterium that attacks other Gram-negative bacteria, including many animal, human, and plant pathogens. This bacterium exhibits a peculiar biphasic life cycle during which two different types of cells are produced: non-replicating highly motile cells (the free-living phase and replicating cells (the intracellular-growth phase. The process of chromosomal replication in B. bacteriovorus must therefore be temporally and spatially regulated to ensure that it is coordinated with cell differentiation and cell cycle progression. Recently, B. bacteriovorus has received considerable research interest due to its intriguing life cycle and great potential as a prospective antimicrobial agent. Although we know that chromosomal replication in bacteria is mainly regulated at the initiation step, no data exists about this process in B. bacteriovorus. We report the first characterization of key elements of initiation of chromosomal replication – DnaA protein and oriC region from the predatory bacterium, B. bacteriovorus. In vitro studies using different approaches demonstrate that the B. bacteriovorus oriC (BdoriC is specifically bound and unwound by the DnaA protein. Sequence comparison of the DnaA-binding sites enabled us to propose a consensus sequence for the B. bacteriovorus DnaA box (5’-NN(A/TTCCACA-3’. Surprisingly, in vitro analysis revealed that BdoriC is also bound and unwound by the host DnaA proteins (relatively distantly related from B. bacteriovorus. We compared the architecture of the DnaA–oriC complexes (orisomes in homologous (oriC and DnaA from B. bacteriovorus and heterologous (BdoriC and DnaA from prey, E. coli or P. aeruginosa systems. This work provides important new entry points toward improving our understanding of the initiation of chromosomal replication in this predatory bacterium.

    la región amazónica boliviana, al norte del país, suscitó profundos cambios en otros departamentos y, entre otras cuestiones, en el mercado laboral. Los departamentos de Beni y de Santa Cruz se constituyeron entonces en reservorios de mano de obra y el flujo migratorio hacia las regiones gomeras del norte fue creciendo proporcionalmente a las necesidades de los empresarios gomeros. Sin embargo, las regiones de origen, y específicamente Santa Cruz, reaccionaron en contra de este “vaciamiento”, desarrollando estrategias para controlar las migraciones o, eventualmente, frenarlas. Este proceso fue acompañado por el despliegue de varias normas novedosas en el ámbito laboral, producto de un debate parlamentario en torno al tema de las migraciones.

    Full Text Available The second-hand clothing trade started widely in Bolivia in 1994. This kind of trade usually involves popular globalization activities, whose practices are often identified by State agencies as illegal, although with natural popular acceptance. It is established within a complex system of networks, and takes advantage of distribution (stock and transfer meshes and knots, with the consequent conformation of connected territorial circuits. This paper aims at analyzing the second-hand clothing trade in three locations: Santa Cruz de la Sierra and Puerto Quijarro (Bolivia, and Corumbá (Brazil. The purpose is to identify the route and the nuances regarding the second-hand clothing distribution network from Santa Cruz de la Sierra to Corumbá, on the Bolivia-Brazil border.

(2) The completion of the SDC technical proposal including a detailed long-term plan for construction. (3) Continuing publication of very detailed physics results from ALEPH concerning τ and b physics, and a precision measurement of electroweak and QCD parameters. (4) Completion of very successful data taking for E-791 at Fermilab, with nearly twice as many events recorded as initially proposed. (5) First measurement of beam polarization at the SLC. These efforts have led to about 15 physics publications this past year centered mainly on topics related to QCD, couplings of flavors to the Z degrees, and heavy flavor decays. Taken as a whole, the results in jets from LEP, the ratio of hadronic to leptonic decays of the τ the leptonic branching fraction of the J/ψ, and the charmonium mass spectrum provide a very consistent set of values of α s at a variety of scales. In particular, they show the running of α s by a factor of about three from m r to m z . Results from LEP also provide evidence of the triple gluon vertex. Similarly, the measurement of the b bar b fraction of Z degrees decays, from the MARK II as well as LEP, provide increasingly better measurements of the Z degree coupling to b quarks. Combined with earlier precision measurements of the Z degrees mass, width, and leptonic branching fractions, the Z degrees decays continue to provide a very precise verification of the Standard Model

    Work for the coming year is a logical continuation of the efforts of the past year. Some special highlights of this past year which are discusses in more detail in this report are: (1) The move onto beamline and start of ZEUS data taking. (2) The completion of the SDC technical proposal including a detailed long-term plan for construction. (3) Continuing publication of very detailed physics results from ALEPH concerning {tau} and b physics, and a precision measurement of electroweak and QCD parameters. (4) Completion of very successful data taking for E-791 at Fermilab, with nearly twice as many events recorded as initially proposed. (5) First measurement of beam polarization at the SLC. These efforts have led to about 15 physics publications this past year centered mainly on topics related to QCD, couplings of flavors to the Z{degrees}, and heavy flavor decays. Taken as a whole, the results in jets from LEP, the ratio of hadronic to leptonic decays of the {tau} the leptonic branching fraction of the J/{psi}, and the charmonium mass spectrum provide a very consistent set of values of {alpha}{sub s} at a variety of scales. In particular, they show the running of {alpha}{sub s} by a factor of about three from m{sub r} to m{sub z}. Results from LEP also provide evidence of the triple gluon vertex. Similarly, the measurement of the b{bar b} fraction of Z{degrees} decays, from the MARK II as well as LEP, provide increasingly better measurements of the Z{degree} coupling to b quarks. Combined with earlier precision measurements of the Z{degrees} mass, width, and leptonic branching fractions, the Z{degrees} decays continue to provide a very precise verification of the Standard Model.

  11. Influence of mercury bioaccessibility on exposure assessment associated with consumption of cooked predatory fish in Spain.

    Predatory fish tend to accumulate high levels of mercury (Hg). Food safety assessment of these fish has been carried out on the raw product. However, the evaluation of the risk from Hg concentrations in raw fish might be modified if cooking and bioaccessibility (the contaminant fraction that solubilises from its matrix during gastrointestinal digestion and becomes available for intestinal absorption) were taken into account. Data on Hg bioaccessibility in raw predatory fish sold in Spain are scarce and no research on Hg bioaccessibility in cooked fish is available. The aim of the present study was to evaluate Hg bioaccessibility in various kinds of cooked predatory fish sold in Spain to estimate their health risk. Both Hg and bioaccessible Hg concentrations were analysed in raw and cooked fish (swordfish, tope shark, bonito and tuna). There were no changes in Hg concentrations during cooking. However, Hg bioaccessibility decreased significantly after cooking (42 ± 26% in raw fish and 26 ± 16% in cooked fish), thus reducing in swordfish and tope shark the Hg concentration to which the human organism would be exposed. In future, cooking and bioaccessibility should be considered in risk assessment of Hg concentrations in predatory fish. Copyright © 2011 Society of Chemical Industry.

    Full Text Available Predatory behavior of Pseudodorus clavatus (Diptera, Syrphidae on aphids tended by ants. In this study, we examined the interactions between myrmecophilous aphids, their ant-guards and a predatory syrphid species, Pseudodorus clavatus (F.. Larvae of this predator were found in the colonies of three aphid species: Aphis gossypii, A. spiraecola and Toxoptera sp., which were tended by eight ant species, especially Camponotus. Hoverfly larvae managed to infiltrate the aphid colonies and consume nymphs. Predator larvae exhibited inconspicuous movements and were not detected by ants which were commonly observed touching and antennating the larvae they come into contact. These results suggest that behavioral and chemical cues are involved in the infiltration and on the successful predation of syrphids upon aphids.

    2016-09-01

    Full Text Available Introduction: Open access (OA medical publishing is growing rapidly. While subscription-based publishing does not charge the author, OA does. This opens the door for “predatory” publishers who take authors’ money but provide no substantial peer review or indexing to truly disseminate research findings. Discriminating between predatory and legitimate OA publishers is difficult. Methods: We searched a number of library indexing databases that were available to us through the University of California, Irvine Libraries for journals in the field of emergency medicine (EM. Using criteria from Jeffrey Beall, University of Colorado librarian and an expert on predatory publishing, and the Research Committee of the International Federation for EM, we categorized EM journals as legitimate or likely predatory. Results: We identified 150 journal titles related to EM from all sources, 55 of which met our criteria for OA (37%, the rest subscription based. Of these 55, 25 (45% were likely to be predatory. We present lists of clearly legitimate OA journals, and, conversely, likely predatory ones. We present criteria a researcher can use to discriminate between the two. We present the indexing profiles of legitimate EM OA journals, to inform the researcher about degree of dissemination of research findings by journal. Conclusion: OA journals are proliferating rapidly. About half in EM are legitimate. The rest take substantial money from unsuspecting, usually junior, researchers and provide no value for true dissemination of findings. Researchers should be educated and aware of scam journals.

    A negative consequence of the rapid growth of scholarly open access publishing funded by article processing charges is the emergence of publishers and journals with highly questionable marketing and peer review practices. These so-called predatory publishers are causing unfounded negative publicity for open access publishing in general. Reports about this branch of e-business have so far mainly concentrated on exposing lacking peer review and scandals involving publishers and journals. There is a lack of comprehensive studies about several aspects of this phenomenon, including extent and regional distribution. After an initial scan of all predatory publishers and journals included in the so-called Beall's list, a sample of 613 journals was constructed using a stratified sampling method from the total of over 11,000 journals identified. Information about the subject field, country of publisher, article processing charge and article volumes published between 2010 and 2014 were manually collected from the journal websites. For a subset of journals, individual articles were sampled in order to study the country affiliation of authors and the publication delays. Over the studied period, predatory journals have rapidly increased their publication volumes from 53,000 in 2010 to an estimated 420,000 articles in 2014, published by around 8,000 active journals. Early on, publishers with more than 100 journals dominated the market, but since 2012 publishers in the 10-99 journal size category have captured the largest market share. The regional distribution of both the publisher's country and authorship is highly skewed, in particular Asia and Africa contributed three quarters of authors. Authors paid an average article processing charge of 178 USD per article for articles typically published within 2 to 3 months of submission.

    The Internet has enabled an easy method to search through the vast majority of publications and has improved the impact of scholarly journals. However, it can also pose threats to the quality of published articles. New publishers and journals have emerged so-called open-access potential, possible, or probable predatory publishers and journals, and so-called hijacked journals. It was our aim to increase the awareness and warn scholars, especially young researchers, how to recognize these journals and how to avoid submission of their papers to these journals. Review and critical analysis of the relevant published literature, Internet sources and personal experience, thoughts, and observations of the authors. The web blog of Jeffrey Beall, University of Colorado, was greatly consulted. Jeffrey Beall is a Denver academic librarian who regularly maintains two lists: the first one, of potential, possible, or probable predatory publishers and the second one, of potential, possible, or probable predatory standalone journals. Aspects related to this topic presented by other authors have been discussed as well. Academics should bear in mind how to differentiate between trustworthy and reliable journals and predatory ones, considering: publication ethics, peer-review process, international academic standards, indexing and abstracting, preservation in digital repositories, metrics, sustainability, etc.

  18. Mercury Bioaccumulation Response to Recent Hg Pollution Abatement in an Oceanic Predatory Fish, Blue Marlin, Versus the Response in a Coastal Predatory Species, Bluefish, in the Western North Atlantic Ocean

    Science.gov (United States)

    Barber, R. T.; Cross, F. A.

    2015-12-01

    The consumption of marine fish, especially predatory species high in the food chain, is the major route through which people in developed countries are exposed to mercury. Recent work on a coastal species, bluefish (Pomatomus saltatrix), determined that the mercury concentration in fish from the U. S. Mid-Atlantic coast decreased 43% from 1972 to 2011. This mercury decline in a coastal marine fish parallels the mercury decline in many freshwater fish in the U.S. and Canada during the same time period. The result heightens interest in determining whether or not there has been any change in mercury concentration in oceanic predatory fish species, that is, fish that are permanent residents of the open ocean, during the past four decades. To answer this question we compared mercury analyses we made in the 1970s on tournament-caught blue marlin (Makaira nigricans) with those we made from 1998 to 2013. This comparison indicates that from the 1970s to 2013 mercury concentration in blue marlin caught in the western North Atlantic Ocean off the U.S. east coast has declined about 45%, a decline that is remarkably similar to the decline reported in coastal bluefish. These results suggest that a large area of the western North Atlantic Ocean is responding to reductions in emissions of mercury in the U.S. and Canada with reduced mercury bioaccumulation in predatory fish.

    Full Text Available Objective: To test the potentiality of the leaf extract of Pedalium murex (P. murex and predatory copepod Mesocyclops longisetus (M. longisetus in individual and combination in controlling the rural malarial vector, Anopheles culicifacies (An. culicifacies in laboratory and field studies. Methods: P. murex leaves were collected from in and around Erode, Tamilnadu, India. The active compounds were extracted with 300 mL of methanol for 8 h in a Soxhlet apparatus. Laboratory studies on larvicidal and pupicidal effects of methanolic extract of P. murex tested against the rural malarial vector, An. culicifacies were significant. Results: Evaluated lethal concentrations (LC50 of P. murex extract were 2.68, 3.60, 4.50, 6.44 and 7.60 mg/L for I, II, III, IV and pupae of An. culicifacies, respectively. Predatory copepod, M. longisetus was examined for their predatory efficacy against the malarial vector, An. culicifacies. M. longisetus showed effective predation on the early instar (47% and 36% on I and II instar when compared with the later ones (3% and 1% on III and IV instar. Predatory efficacy of M. longisetus was increased (70% and 45% on I and II instar when the application was along with the P. murex extract. Conclusions: Predator survival test showed that the methanolic extract of P. murex is non-toxic to the predatory copepod, M. longisetus. Experiments were also conducted to evaluate the efficacy of methanolic extract of P. murex and M. longisetus in the direct breeding sites (paddy fields of An. culicifacies. Reduction in larval density was very high and sustained for a long time in combined treatment of P. murex and M. longisetus.

  5. Optimal strategies and complexity: a theoretical analysis of the anti-predatory behavior of the hare.

    Science.gov (United States)

    Focardi, S; Rizzotto, M

    1999-09-01

    Predator-prey relationships involving rabbits and hares are widely studied at a long-term population level, while the short-term ethological interactions between one predator and one prey are less well documented. We use a physiologically-based model of hare behavior, developed in the framework of artificial intelligence studies, to analyse its sophisticated anti-predatory behavior. The hares use to stand to the fox in order to inform it that its potential prey is alerted. The behavior of the hare is characterized by specific standing and flushing distances. We show that both hare survival probability and body condition depend on habitat cover, as well as on the ability of the predator to approach-undetected-a prey. We study two anti-predatory strategies, one based on the maximization of the survival probability and the other on the maximization of the body conditions of the hare. Despite the fact that the two strategies are not independent, they are characterized by quite different behavioral patterns. Field estimates of flushing and standing distances are consistent with survival maximization. There exists an optimal anti-predatory strategy, characterized by a flushing distance of 20 m and a standing distance of 30 m, which is optimal in a large set of environmental conditions with a sharp fitness advantage with respect to suboptimal strategies. These results improve our understanding of the anti-predatory behavior of the hare and lend credibility to the optimality approach in the behavioral analysis, showing that even for complex organisms, characterized by a large network of internal constraints and feedback, it is possible to identify simple optimal strategies with a large potential for selection.

  3. Analysis of thirteen predatory publishers: a trap for eager-to-publish researchers.

    Science.gov (United States)

    Bolshete, Pravin

    2018-01-01

    To demonstrate a strategy employed by predatory publishers to trap eager-to-publish authors or researchers into submitting their work. This was a case study of 13 potential, possible, or probable predatory scholarly open-access publishers with similar characteristics. Eleven publishers were included from Beall's list and two additional publishers were identified from a Google web search. Each publisher's site was visited and its content analyzed. Publishers publishing biomedical journals were further explored and additional data was collected regarding their volumes, details of publications and editorial-board members. Overall, the look and feel of all 13 publishers was similar including names of publishers, website addresses, homepage content, homepage images, list of journals and subject areas, as if they were copied and pasted. There were discrepancies in article-processing charges within the publishers. None of the publishers identified names in their contact details and primarily included only email addresses. Author instructions were similar across all 13 publishers. Most publishers listed journals of varied subject areas including biomedical journals (12 publishers) covering different geographic locations. Most biomedical journals published none or very few articles. The highest number of articles published by any single biomedical journal was 28. Several editorial-board members were listed across more than one journals, with one member listed 81 times in different 69 journals (i.e. twice in 12 journals). There was a strong reason to believe that predatory publishers may have several publication houses with different names under a single roof to trap authors from different geographic locations.

    Full Text Available Abstract The purpose of this study was to evaluate the predatory activity of the nematode Butlerius spp. and fungal isolates of Duddingtonia flagrans, Clonostachys rosea, Arthrobotrys musiformis and Trichoderma esau against H. contortus infective larvae (L3 in grass pots. Forty-eight plastic gardening pots containing 140 g of sterile soil were used. Panicum spp. grass seeds (200 mg were sown into each pot and individually watered with 10 mL of tap water. Twelve days after seeding, the pots were randomly divided into 6 groups (n=8. Two thousand H. contortus infective larvae (L3 were added to each group. Additionally, the following treatments were established: Group 1 – 2000 Butlerius spp. larvae; group 2 – A. musiformis (1x107 conidia; group 3 – T. esau (1x107 conidia; group 4 – C. rosea (1x107 conidia, group 5 – D. flagrans (1x107conidia and Group 6 – no biological controller (control group. The larval population of H. contortus exposed to Butlerius spp. was reduced by 61.9%. Population reductions of 90.4, 66.7, 61.9 and 85.7% were recorded in the pots containing A. musiformis, T. esau, C. rosea and D. flagrans, respectively. The results of this study indicate that the predatory nematode Butlerius spp. and the assessed fungi display an important predatory activity can be considered suitable potential biological control agents.

    2017-01-01

    Full Text Available http://dx.doi.org/10.5007/2175-7968.2017v37n1p230 The medical literature consumed and produced by the Oswaldo Cruz Institute and the circulation of its personnel in foreign institutions from its beginnings in 1900 through the Vargas coup d’état in Brazil in 1930 testify to the complex, multilingual and international nature of scientific networking in and beyond the belle époque and challenge notions of behavior associated with colonial economic models. To explore the parameters of the Institute’s early organizational culture with respect to language, three of its publications from this period will be examined: a 1911 promotional booklet in German, which details the Institute’s journal holdings and the publications of its researchers; a 1929 English-language travelogue of leprosy treatment centers worldwide; and the journal Memórias do Instituto Oswaldo Cruz (1909-, which published articles in five languages during this period. The results indicate that the Institute’s flexible, avidly multilingual language policy, partially the result of Brazil’s peripheral, neutral political situation, led to a very strong multilateral position in the scientific community that provided both visibility and recognition as a full peer in the then-internationally emerging field of Tropical Medicine.

  12. Petro-States - Predatory or Developmental?

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2000-10-01

    Political attention is increasing on the glaring contradiction in most oil-rich countries between natural abundance and economic and social misery. How can it be that oil is not a blessing, but becomes a curse? Although drawing on economic analysis (Dutch disease), the analytical framework established in this report on Angola and Azerbaijan pays special attention to political and institutional factors and concentrates on the role of the state. Selected variables that are likely to decide whether the petro-states become ''predatory'' or ''developmental'' are studied for both countries. The analysis indicates a danger that oil resources will continue to trickle away instead of trickling down to the benefit of the broader Angolan and Azerbaijani population. Concerted action by international oil companies and the Bretton Woods institutions provides the best hope of moving the present political leadership in Angola and Azerbaijan into a developmental direction.

  13. Constraining back-arc basin formation in the eastern Coral Sea: preliminary results from the ECOSAT voyage

    The eastern Coral Sea region is an underexplored area at the northeastern corner of the Australian plate, where long-lived interaction between the Pacific and Australian plate boundaries has resulted in an intricate assemblage of deep oceanic basins and ridges, continental fragments and volcanic products. A paucity of marine geophysical and geological data from this complex region has resulted in the lack of a clear conceptual framework to describe its formation, ultimately affecting our understanding of the connection between the plate boundaries of the SW Pacific and SE Asia. In particular, the tectonic relationship between two back-arc basins, the Santa Cruz and d'Entrecasteaux Basins, and the South Rennell Trough, has yet to be resolved. In October-November, 2012, we collected 6,200 km of marine magnetic, 6,800 km of gravity and over 13,600 km2 of swath bathymetry data from the eastern Coral Sea onboard the RV Southern Surveyor. A complementary dredging program yielded useful samples from 14 seafloor sites. Our preliminary geochemical interpretation of the dredge samples obtained from the South Rennell Trough reveal volcanic rocks resembling MORB or BABB-type basalts, similar in composition to the recently re-analysed and dated ORSTOM dredges from the area that yielded ~28 Ma MORB-like basalts. Swath bathymetry profiles from the Santa Cruz Basin reveal that the South Rennell Trough extends into this basin, with seafloor spreading fabric being parallel to the trough. Preliminary analysis of the three full and four partial new magnetic anomaly profiles across the Santa Cruz Basin, coupled with limited existing profiles, reveals that the basin may have formed between Chrons 13-18 (~32-38 Ma), with an extinct spreading ridge along the inferred continuation of the South Rennell Trough, consistent with ORSTOM age dates. Our results suggest that the South Rennell Trough is an extinct southwestward propagating spreading ridge, which may have initiated along a pre

    Full Text Available This paper studies Fernando Cruz Kronfly´s novel Destierro (2012 through categories like anachronism, presenteism and memory (Didi-Huberman, Hartog, Benjamin, among others in order to investigate the particular way in which the novel temporalizes the experience of exile. Destierro part from a present that, in perpetual motion, leading to a present of the already-gone, a narrative temporality made by absences. The time in this temporality and its links generated produces what we called ghost community, a kind of community which govern relations between that remains present and what does not.

La demanda de agua que se generará a partir de los planes de expansión de la actividad productiva y la que se originará por el aumento poblacional, hace necesario que se realicen acciones para recuperar cursos afectados, tomando como punto de partida la identificación y caracterización de efluentes descargados. Los estudios realizados previamente se han basado en un tratamiento global o en muestreos puntuales sin difereciar, cuantificar o cualificar en forma sistemática las alteraciones ocasionadas por los distintos aportes. En éste trabajo se identificó los diferentes vertidos al arroyo y se determinó parámetros fisicoquímicos durante dos campañas (invierno y verano que permitieron caracterizar los individuos a partir de un tratamiento estadístico multivariado de los datos. Los resultados arrojaron valores de pH dentro del rango de la neutralidad o ligeramente básicos y la alcalinidad, otro de los factores que determinan la disolución de metales, dio valores que les confiere a las aguas capacidad amortiguadora beneficiosa. Como conclusión estadística general, los efluentes quedaron diferenciados principalmente entre los que aportan importantes cantidades de sólidos y metales totales en suspención (Planta depuradora de carbón y la Central térmica, de los que no lo hacen (Minas en explotación y abandonadas y efluentes Poblacionales. Éstos últimos se caracterizaron además por una elevada alcalinidad y contenidos de cloruros,calcio y dureza.

    In this work are presented the results of water quality of seven springs (San Antonio Enchisi, Las Fuentes, El Cerro, Pasteje, Los Reyes, Santa Cruz and Tiacaque) and two water wells (Jocotitlan No. 2 and La Providencia No. 35) which are used for human consumption and that are located surrounding area to Jocotitlan volcano, state of Mexico. It was determined the 222 Rn concentration through liquid scintillation, the 226 Ra by Gamma spectroscopy, the physical-chemical parameters (major elements) and bacteriological, using standardized methods. The minor elements and trace in solution were determined by Icp-Ms mass spectroscopy. The water quality was established in function of the standing standards. Therefore Las Fuentes, El Cerro, Santa Cruz, Tiacaque springs and the Jocotitlan No. 2 well, are drinkable water. So, Pasteje, Los Reyes, San Antonio Enchisi springs and the La Providencia No. 35 well are chemically drinkable but presenting bacteriological pollution. (Author)

    Full Text Available This study evaluated the effects on the development and predatory capacity of Podisus nigrispinus fed on Spodoptera frugiperda that have ingested different concentrations of neem oil. The predatory capacity of Podisus nigrispinus was assessed, separating nymphs (fourth instar and adults (males and females. The treatments consisted of S. frugiperda larvae reared in neem oil aqueous solutions (0.077, 0.359 and 0.599%, deltamethrin EC 25 (0.100% and control arranged in a completely randomized design, with ten replicates. Insects were offered three larval densities (one, three and six, in the third or fourth instars. The predated larvae were examined at 24 and 48 hours after the beginning of the experiment. Biological parameters of Podisus nigrispinus were evaluated in groups of ten second-instar nymphs transferred to pots, in five replicates. Insects were offered 2-6 third and/or fourth-instar larvae reared in the same neem oil concentrations in a completely randomized design. The following parameters were evaluated: duration of each nymph stage (days, nymph mortality (%, weight of fifth-instar nymphs (mg, sex ratio, weight of males and females (mg and longevity of unfed adults (days. The predatory capacity of nymphs and adults of Podisus nigrispinus was influenced by the neem oil at the concentrations of 0.359% and 0.599% in the highest density. The concentration of 0.359% lengthened the nymphal stage and the concentration of 0.599% reduced the weight of males.

    Tumacácori National Historical Park protects the culturally important Mission, San José de Tumacácori, while also managing a portion of the ecologically diverse riparian corridor of the Santa Cruz River. This report describes the methods and quality assurance procedures used in the collection of water samples for the analysis of Escherichia coli (E. coli), microbial source tracking markers, suspended sediment, water-quality parameters, turbidity, and the data collection for discharge and stage; the process for data review and approval is also described. Finally, this report provides a quantitative assessment of the quality of the E. coli, microbial source tracking, and suspended sediment data.The data-quality assessment revealed that bias attributed to field and laboratory contamination was minimal, with E. coli detections in only 3 out of 33 field blank samples analyzed. Concentrations in the field blanks were several orders of magnitude lower than environmental concentrations. The microbial source tracking (MST) field blank was below the detection limit for all MST markers analyzed. Laboratory blanks for E. coli at the USGS Arizona Water Science Center and laboratory blanks for MST markers at the USGS Ohio Water Microbiology Laboratory were all below the detection limit. Irreplicate data for E. coli and suspended sediment indicated that bias was not introduced to the data by combining samples collected using discrete sampling methods with samples collected using automatic sampling methods.The split and sequential E. coli replicate data showed consistent analytical variability and a single equation was developed to explain the variability of E. coli concentrations. An additional analysis of analytical variability for E. coli indicated analytical variability around 18 percent relative standard deviation and no trend was observed in the concentration during the processing and analysis of multiple split-replicates. Two replicate samples were

    Full Text Available Dependence and indiscriminate use of chemical anthelmintics as the sole method for controlling gastrointestinal nematodes (GIN of cattle causes problems in the environment, public health, and the productivity of cattle. It is important to develop non-chemical control strategies. Nematophagous fungi can be a viable and promising alternative for the control of these endoparasites. This study aimed to isolate, identify and evaluate in vitro the potential of nematophagous fungi from Cundinamarca on L3 larvae of gastrointestinal nematodes of cattle. 60 soil samples from cattle ranches were sown in Petri boxes containing agar-water for trapping fungi, and three strains of the fungus Arthrobotrys oligospora (L1, XVIII, and XXI and one of Arthrobotrys musiformis (XXIV were identified by morphometric keys. 1 x 106 conidia or chlamydospores of each fungi were used, which faced 100 nematode larvae. Isolate XXIV (A. musiformis showed greater predatory capacity (96.8% than isolates (A. oligospora XVIII, L1, and XXI (69.68, 71.1, and 87.62%, respectively. There were no statistically significant differences (p > 0.05 among the strains with more predatory capacity. This is the first record of in vitro identification and evaluation of the predatory capacity of A. oligospora and A. musiformis, native fungi from Cundinamarca. The results suggest that these fungi could be used as biocontrol agents of nematodes in cattle.

    Invasive predators may change the structure of invaded communities through predation and competition with native species. In Europe, the invasive signal crayfish Pacifastacus leniusculus is excluding the native white clawed crayfish Austropotamobius pallipes. This study compared the predatory functional responses and prey choice of native and invasive crayfish and measured impacts of parasitism on the predatory strength of the native species. Invasive crayfish showed a higher (>10%) prey (Gammarus pulex) intake rate than (size matched) natives, reflecting a shorter (16%) prey handling time. The native crayfish also showed greater selection for crustacean prey over molluscs and bloodworm, whereas the invasive species was a more generalist predator. A. pallipes parasitised by the microsporidian parasite Thelohania contejeani showed a 30% reduction in prey intake. We suggest that this results from parasite-induced muscle damage, and this is supported by a reduced (38%) attack rate and increased (30%) prey handling time. Our results indicate that the per capita (i.e., functional response) difference between the species may contribute to success of the invader and extinction of the native species, as well as decreased biodiversity and biomass in invaded rivers. In addition, the reduced predatory strength of parasitized natives may impair their competitive abilities, facilitating exclusion by the invader.

    The residual effects of several reduced-risk and conventional miticides were evaluated in strawberries (Fragaria × ananassa Duchesne) on the twospotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) and on 2 predatory mites, Neoseiulus californicus McGregor and Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae). Experiments were conducted in the laboratory and greenhouse. The greenhouse experiments also tested the direct effects of the miticides on TSSM. The efficacy of conventional and reduced-risk miticides was evaluated on strawberry leaf discs and on whole plants for control of TSSM. Furthermore, the residual effects of these miticides were evaluated on whole strawberry plants against selective predatory mites. For TSSM, 5 treatments were evaluated: a conventional miticide; fenbutatin-oxide (Vendex[reg]) and 3 reduced-risk miticides; binfenazate (Acramite 50WP[reg]), activated garlic extract (Repel[reg]), sesame seed and castor oil (Wipeout[reg]), and a water-treated control. For predatory mites, the residual effects of only Acramite[reg] and Vendex[reg] were evaluated. Acramite[reg] was the most effective acaricide in reducing TSSM populations in both the laboratory and greenhouse experiments. Vendex[reg] and Wipeout[reg] were also effective in the laboratory, but did not cause significant reduction of TSSM in the greenhouse. Repel[reg] was the least effective of the 4 pesticides evaluated. Neither Acramite[reg] nor Vendex[reg] had a significant effect on either predatory mite species. However, there appeared to be more predatory mites on the Vendex[reg]-treated plants than on the Acramite[reg]-treated plants. There were significantly more predatory mites of both species on the cue plants, which were inoculated with TSSM versus the non-cue plants, which were not inoculated. (author) [es

    In this work are presented the results of water quality of seven springs (San Antonio Enchisi, Las Fuentes, El Cerro, Pasteje, Los Reyes, Santa Cruz and Tiacaque) and two water wells (Jocotitlan No. 2 and La Providencia No. 35) which are used for human consumption and that are located surrounding area to Jocotitlan volcano, state of Mexico. It was determined the {sup 222} Rn concentration through liquid scintillation, the {sup 226} Ra by Gamma spectroscopy, the physical-chemical parameters (major elements) and bacteriological, using standardized methods. The minor elements and trace in solution were determined by Icp-Ms mass spectroscopy. The water quality was established in function of the standing standards. Therefore Las Fuentes, El Cerro, Santa Cruz, Tiacaque springs and the Jocotitlan No. 2 well, are drinkable water. So, Pasteje, Los Reyes, San Antonio Enchisi springs and the La Providencia No. 35 well are chemically drinkable but presenting bacteriological pollution. (Author)

    The microbiome of three different sites at the Peruvian Pacific coast was analyzed, revealing a lower bacterial biodiversity at Isla Foca than at Paracas and Manglares, with 89 bacterial genera identified, as compared to 195 and 173 genera, respectively. Only 47 of the bacterial genera identified were common to all three sites. In order to obtain promising strains for the putative production of novel antimicrobials, predatory bacteria were isolated from these sampling sites, using two different bait organisms. Even though the proportion of predatory bacteria was only around 0.5% in the here investigated environmental microbiomes, by this approach in total 138 bacterial strains were isolated as axenic culture. 25% of strains showed antibacterial activity, thereby nine revealed activity against clinically relevant methicillin resistant Staphylococcus aureus (MRSA) and three against enterohemorrhagic Escherichia coli (EHEC) strains. Phylogeny and physiological characteristics of the active strains were investigated. First insights into the chemical basis of the antibacterial activity indicated the biosynthetic production of the known compounds ariakemicin, kocurin, naphthyridinomycin, pumilacidins, resistomycin, and surfactin. However, most compounds remained elusive until now. Hence, the obtained results implicate that the microbiome present at the various habitats at the Peruvian coastline is a promising source for heterotrophic bacterial strains showing high potential for the biotechnological production of antibiotics.

  14. The rhetorical construction of the predatorial virus: a Burkian analysis of nonfiction accounts of the Ebola virus.

    Science.gov (United States)

    Weldon, R A

    2001-01-01

    Over the past 5 years, a new subgenre of horror films, referred to as plague films, has turned our focus to the threat of a hemorrhagic viral pandemic, comparable to the Spanish Flu epidemic of 1916. Based on the Ebola viral outbreaks of 1976, various writers have presented their accounts under the guise of increasing interest and prevention strategies. Disregarding inappropriate health care practices as the cause of these epidemics, accountability is refocused onto the rhetorically constructed, predatory nature of the virus. By employing Burke's theory of dramatism and pentadic analysis, the author examines this rhetorical construction of Ebola as a predatorial virus and its implications for public perceptions of public health endeavors.

    2001-02-01

    The toxicities of the herbicide glufosinate-ammonium to three predatory insect and two predatory mite species of Tetranychus urticae Koch were determined in the laboratory by the direct contact application. At a concentration of 540 ppm (a field application rate for weed control in apple orchards), glufosinate-ammonium was almost nontoxic to eggs of Amblyseius womersleyi Schicha, Phytoseiulus persimilis Athias-Henriot, and T. urticae but highly toxic to nymphs and adults of these three mite species, indicating that a common mode of action between predatory and phytophagous mites might be involved. In tests with predatory insects using 540 ppm, glufosinate-ammonium revealed little or no harm to larvae and pupae of Chrysopa pallens Rambur but was slightly harmful to eggs (71.2% mortality), nymphs (65.0% mortality), and adults (57.7% mortality) of Orius strigicollis Poppius. The herbicide showed no direct effect on eggs and adults of Harmonia axyridis (Pallas) but was harmful, slightly harmful, and harmless to first instars (100% mortality), fourth instars (51.1% mortality), and pupae (24.5% mortality), respectively. The larvae and nymphs of predators died within 12 h after treatment, suggesting that the larvicidal and nymphicidal action may be attributable to a direct effect rather than an inhibitory action of chitin synthesis. On the basis of our data, glufosinate-ammonium caused smaller effects on test predators than on T. urticae with the exception of P. persimilis, although the mechanism or cause of selectivity remains unknown. Glufosinate-ammonium merits further study as a key component of integrated pest management.

    The article analyzes reports from two scientific journeys into the Amazon conducted by the Instituto Oswaldo Cruz, in 1910 and 1913, under the leadership of Oswaldo Cruz and Carlos Chagas, respectively. These reports contributed to the construction of representations and images of the region. Field observations not only provided data for the study and control of tropical diseases but also had a hand in the movement to denounce the serious sanitation conditions under which rubber workers labored. Journeys through the Amazon valley put the scientists in direct contact with the environment and with sick populations; these travels also made them face the huge challenges of learning about malaria and trying to control it. Analyses of these reports are part of studies on 'portraits of Brazil', which raise issues within the history of public health policies. In this endeavor to reveal the process by which scientific records are constructed, we worked with primary sources,from manuscripts to official texts.

    The Santa Fe Alliance for Science (SFAFS) was founded in May, 2005. SFAFS exists to provide assistance in K-14 math and science education in the greater Santa Fe area. It does this via extensive programs (1) in math and science tutoring at Santa Fe High School, Santa Fe Community College and to a lesser degree at other schools, (2) science fair advising and judging, (3) its ``Santa Fe Science Cafe for Young Thinkers'' series, (4) a program of professional enrichment for K-12 math and science teachers, and (5) a fledging math intervention program in middle school math. Well over 150 STEM professionals, working mostly as volunteers, have contributed since our beginning. Participation by students, parents and teachers has increased dramatically over the years, leading to much more positive views of math and science, especially among elementary school students and teachers. Support from the community and from local school districts has been very strong. I will present a brief status report on SFAFS activities, discuss some of the lessons learned along the way and describe briefly some ideas for the future. More information can be found at the SFAFS website, www.sfafs.org.

    Phytoseiulus persimilis is a predatory mite that in absence of vision relies on the detection of herbivore-induced plant odors to locate its prey, the two-spotted spider-mite Tetranychus urticae. This herbivorous prey is feeding on leaves of a wide variety of plant species in different families. The

Objetivo secundário é verificar a associação de THAS com variáveis demográficas. Todos os moradores da área do PSF avaliada maiores de 14 anos foram convidados a participar. A amostra total analisada foi composta de 1.122 indivíduos. A prevalência encontrada de THAS foi de 38% (IC95%: 35,12-40,88. Sexo feminino, baixa escolaridade e situação ocupacional desfavorável mostraram associação independente com THAS. A alta prevalência de THAS na área estudada demonstra a importância destes transtornos em termos de saúde pública, e pode trazer alguma contribuição para o entendimento da alta incidência de mortalidade por suicídio verificada em Santa Cruz do Sul na última década (4,66 vezes maior que a incidência nacional.

  5. Predatory Mite Attraction to Herbivore-induced Plant Odors is not a Consequence of Attraction to Individual Herbivore-induced Plant Volatiles

    Predatory mites locate herbivorous mites, their prey, by the aid of herbivore-induced plant volatiles (HIPV). These HIPV differ with plant and/or herbivore species, and it is not well understood how predators cope with this variation. We hypothesized that predators are attracted to specific compounds in HIPV, and that they can identify these compounds in odor mixtures not previously experienced. To test this, we assessed the olfactory response of Phytoseiulus persimilis, a predatory mite that preys on the highly polyphagous herbivore Tetranychus urticae. The responses of the predatory mite to a dilution series of each of 30 structurally different compounds were tested. They mites responded to most of these compounds, but usually in an aversive way. Individual HIPV were no more attractive (or less repellent) than out-group compounds, i.e., volatiles not induced in plants fed upon by spider-mites. Only three samples were significantly attractive to the mites: octan-1-ol, not involved in indirect defense, and cis-3-hexen-1-ol and methyl salicylate, which are both induced by herbivory, but not specific for the herbivore that infests the plant. Attraction to individual compounds was low compared to the full HIPV blend from Lima bean. These results indicate that individual HIPV have no a priori meaning to the mites. Hence, there is no reason why they could profit from an ability to identify individual compounds in odor mixtures. Subsequent experiments confirmed that naive predatory mites do not prefer tomato HIPV, which included the attractive compound methyl salicylate, over the odor of an uninfested bean. However, upon associating each of these odors with food over a period of 15 min, both are preferred. The memory to this association wanes within 24 hr. We conclude that P. persimilis possesses a limited ability to identify individual spider mite-induced plant volatiles in odor mixtures. We suggest that predatory mites instead learn to respond to prey

    2016-07-01

    Full Text Available Transforming mature tourism resorts has evolved toward a greater involvement of public authorities and away from the mere renovation of public spaces. Authorities today are required to lead the reorganization of tourism activities through the development of co-operative networks between all stakeholders involved. In this paper, a participatory integrated approach has been designed and implemented in collaboration with Spanish authorities and the tourism sector to propose a strategy to achieve the renovation of tourism resorts. This methodology was applied to Puerto de la Cruz, the oldest tourism destination in the Canary Islands and a clear paradigm of a consolidated resort. The objective is to define and implement policies to transform Puerto de la Cruz into a more sustainable tourism destination.

    Full Text Available A pesquisa teve como objetivo geral avaliar participação da erva mate (Ilex paraguariensis no contexto econômico do Município de Cruz Machado no estado do Paraná, suas perspectivas de desenvolvimento local e geração de renda no sistema de agricultura familiar. A metodologia utilizada foi a pesquisa bibliográfica e consulta on line nos principais órgão e secretárias, mais o trabalho de campo com a averiguação de algumas propriedades rurais do município de Cruz Machado. Nos sistemas de agricultura familiar a logística das ocupações do relevo está associada às características geomorfológicas e ao tamanho das propriedades agropecuárias. Em Cruz Machado predomina o sistema de agricultura familiar, e a erva mate sempre foi uma alternativa extra na complementação da renda dos produtores, e no ano de 2013 contribuiu em mais de 15% do PIB anual do município. E hoje a produção da erva mate representa uma complementação na renda das famílias do município de Cruz Machado, mas que poderá ter uma maximização de produção aliada a características geoecológicas da região e contribuir para o desenvolvimento local.

  19. Local smoke-free policy development in Santa Fe, Argentina.

    Sebrié, Ernesto M; Glantz, Stanton A

    2010-04-01

    To describe the process of approval and implementation of a comprehensive smoke-free law in the province of Santa Fe, Argentina, between 2005 and 2009. Review of the Santa Fe smoke-free legislation, articles published in local newspapers and documentation on two lawsuits filed against the law, and interviews with key individuals in Santa Fe. Efforts to implement smoke-free policies in Santa Fe began during the 1990s without success, and resumed in 2005 when the provincial Legislature approved the first 100% smoke-free subnational law in Argentina. There was no strong opposition during the discussions within the legislature. As in other parts of the world, pro-tobacco industry interests attempted to block the implementation of the law using well known strategies. These efforts included a controversy media campaign set up, the creation of a hospitality industry association and a virtual smokers' rights group, the introduction of a counterproposal seeking modification of the law, the challenge of the law in the Supreme Court, and the proposal of a weak national bill that would 'conflict' with the subnational law. Tobacco control advocates sought media attention as a strategy to protect the law. Santa Fe is the first subnational jurisdiction in Latin America to have enacted a comprehensive smoke-free policy following the recommendations of the World Health Organization (WHO) Framework Convention on Tobacco Control. After 3 years of implementation, pro-tobacco industry forces failed to undermine the law. Other subnational jurisdictions in Argentina, as well as in Mexico and Brazil are following the Santa Fe example.
