    The following species are recorded from the coasts of São Tomé and Príncipe for the first time: the ciliate Zoothamnium niveum, the black coral Antipathella wollastoni, the zoanthid Isaurus tubercularis, and the shrimp Latreutes fucorum. The presence of the black coral Tanacetipathes spinescens and of the shrimp Cinetorhynchus rigens is confirmed. The presence of the crab Platypodiella picta at São Tome Island is confirmed and a possibly undescribed species of Platypodiella is recorded from Príncipe Island. Mistaken records of Stichopathes lutkeni are corrected: the species at São Tomé and Príncipe is Stichopathes occidentalis.info:eu-repo/semantics/publishedVersio

    Hawksbill (Eretmochelys imbricata) and Green Turtle (Chelonia mydas) Nesting and Beach Selection at Príncipe Island, West Africa

    Hawksbills (Eretmochelys imbricata) and green turtles (Chelonia mydas) are the predominant nesting sea turtle species on the beaches of Príncipe Island in the Gulf of Guinea. The extent of nesting has been largely unknown, but such information is essential for management and conservation. Our study is the first island-wide nesting assessment. Results from the survey, conducted from 1 December 2009 to 18 January 2010 (during peak nesting season), show that the potential suitable nesting area (10 km) is scattered around the island’s 50 beaches. Sea turtles nested on 32 of the beaches (hawksbills, 20; green turtles, 28) and used 7.5 km of the suitable nesting habitat (hawksbills, 5.8 km; green turtles, 7.0 km). We estimated that 101 (95% CI = 86–118) clutches were deposited by 17-29 hawksbills and 1088 (95% CI = 999–1245) clutches were deposited by 166-429 green turtles on Príncipe from November 2009 to February 2010 (nesting season). Long-term green turtle nest count data collected from 2007/08 to 2015/16 suggest a positive trend. Analyses of clutch densities in relation to beach characteristics suggested that both species preferred areas where human presence is lower, which coincided with the most sheltered areas. These findings should be used to inform coastal planning and minimize impacts on nesting beaches, as Príncipe is currently targeted for tourism development. Overall, results highlight that Príncipe beaches are very important for the conservation of West African hawksbill and green turtle populations.info:eu-repo/semantics/publishedVersio

    "They Come, They Fish, and They Go:” EC Fisheries Agreements with Cape Verde and São Tomé e Príncipe

    Get PDF
    Fisheries agreements with the European Community (EC) are an important component of the fisheries sector in Cape Verde and São Tomé e Príncipe, constituting today a key source of income for the respective fisheries administration. In spite of this, and of the fact that these agreements have been renewed several times over the past decades, challenges remain in domains such as control and communication of fishing activities, follow-up of financial counterparts, and integration of European fleets’ operations with the Cape Verdean and Santomean economies. This paper analyzes the EC fisheries agreements with Cape Verde and São Tomé e Príncipe in terms of those domains, considering both the contents of the agreements and their practical implementation. The fisheries sector in each of these countries is reviewed, as are some of the fundamentals and criticisms of EC fisheries agreements. It is argued that the agreements with Cape Verde and São Tomé e Príncipe will not live up to the stated objectives of sustainability and responsibility in fisheries until improvements are made to the control of EC vessels, the follow-up of funds paid by the EC, and the size and diversity of benefits accruing to the fisheries and related sectors in the two countrie

    OpenAIRE infrastructure and services: advancing Open Science

    13th International Open Repositories Conference, June 4th-7th, Bozeman, Montana, USA.OpenAIRE has established itself as a key and sustainable infrastructure for giving access to Open Access publications in Europe and beyond, progressively providing access to datasets, software and other research artefacts. From its outset, OpenAIRE has pursued a service-driven design to engage all stakeholders and the current service portfolio (covering all e-Infrastructure layers) targets a variety of users, namely researchers, content providers, funders and research communities. OpenAIRE infrastructure is currently able to deliver a set of relevant services for content providers managers. The OpenAIRE Literature Broker Service is a tool operating on top of the OpenAIRE information graph and supports repository managers with a web dashboard where they can monitor all their repositories and can view the enrichments suggested by the information graph. Funders can currently benefit from a set of services to monitor research outputs and impact and to integrate a body of resources in their ecosystems. OpenAIRE has now successfully applied the model and services developed for the European Commission to other funders, mainly from European Union. OpenAIRE is working closely with existing Research Infrastructures and research communities to extend its service portfolio by introducing two new services implementing the concept of “Open Science as a Service”: Research Community Dashboard and Catch-All Broker Service. OpenAIRE-Advance, the new phase of OpenAIRE infrastructure, continues the mission of OpenAIRE to support the Open Access and Open Data mandates in Europe. By sustaining the current infrastructure, comprised of a human network and technical services, it consolidates its achievements while working to shift the momentum among its communities to Open Science, aiming to be a trusted e-Infrastructure within the realms of the European Open Science Cloud.info:eu-repo/semantics/publishedVersio

    The importance of local-scale factors for forest ecosystems in drylands

    Get PDF
    Forests in drylands are crucial to maintaining important ecosystem services. However, dryland forests are being degraded by multiple pressures, mainly climate change and land-use intensification, leading to an increase in tree mortality and decreasing natural regeneration. Therefore, is critical to understand the underlying environmental factors that are limiting tree cover and distribution in dryland forests. The aim of this thesis was to unravel the contribution of local-scale factors, mainly microclimatic conditions, to explain forest performance in different stages of tree development: productivity, mortality and natural regeneration in oak woodlands of Mediterranean drylands. Particularly, we aimed to i) compare the relative importance of local-scale factors with broad-scale factors in explaining tree productivity, ii) identify what are the most important local-scale factors explaining tree productivity, mortality and regeneration, and iii) understand how microclimate can influence tree productivity, mortality and regeneration. For that, we used broad- (>500 m) and local-scale (<500 m) factors as main predictors of tree productivity, mortality and natural regeneration with high spatial resolution. Our approach used geographic information, remote sensing, multivariate statistics, and field data. This thesis showed that: i) local-scale factors and their interaction with broad-scale factors explained more tree productivity variance than broad-scale factors alone, ii) the most important local-scale factors that limited tree productivity were related to microclimatic conditions, particularly water availability in the soil and Potential Solar Radiation, iii) tree mortality increases in areas where water availability in the soil derived from topographic indices was lower or when groundwater was more distant from the tree roots, iv) very dry microclimatic conditions are the main limiting factor for tree natural regeneration in the long term (more than 60 years), particularly in the tree establishment phase. These results highlight the importance of including variables with a high spatial resolution to model and map the potential of tree productivity, mortality and regeneration over space and time. Modelling dryland forests' response using local-scale factors improves the precision of reforestation and restoration plans, increasing management efficiency and the long-term sustainability of these forests

    Coello's Spanish "Hamlet" (1872)

    Get PDF
    El príncipe Hamlet, by the Spanish playwright Carlos Coello (1850-1888), premiered in Madrid on November 22, 1872 and, described by the author as a “trágico-fantástico” drama, is unique in the history of Spanish translations and adaptations of Shakespeare’s Hamlet. The play reflects Spain’s late introduction to Shakespeare’s work, in comparison to other European countries. In the Prologue, Coello, who calls Shakespeare “the English Calderón,” insists that his play is a completely new play, “subject to the needs of the Spanish scene and the special conditions of our audience.” Built from the original text, the play includes dialogues and soliloquies of the original and much of its plot. One of the play’s most interesting features is that of the development of the characters and of the subtexts—including such topics as lost honor and the unequal relationship between men and women. In this way, El príncipe Hamlet becomes a rewrite of Shakespeare’s Hamlet, emblematic of the Spanish theatrical tradition of the Golden Age, which was revitalized in the first half of the 19th century in Spain. The Spanish theatre of the 19th century, with its romantic and nationalistic bent, looked to its own 16th and 17th century plays as models, rather than importing foreign works. Nevertheless, Coello’s El príncipe Hamlet exposed the Spanish public to Shakespeare’s work at a time when performances of his plays in Spain were scarce and translations of his works were still based on previous versions done by the French.Universidad de Málaga.
