Descripción de un nuevo limácido de Menorca (Islas Baleares): Gigantomilax (Vitrinoides) benjaminus sp. n. (Gastropoda, Pulmonata)
2008
We describe a new endemic limacid slug, Gigantomilax (Vitrinoides) benjaminus n. sp. and we compare it with the nearest species, particularly with Gigantomilax (V.) majoricensis, another Balearic endemism. Characteristic features of this new species include its small size, translucid and smooth body, and totally grey dorsum with no bands or spots. The reproductive system shows a well developed vas deferens surrounded by the distal part of prostatic gland, a thin penial retractor muscle, swollen prostate and small distal genitalia. The recent redescription of Limax majoricensis by Wiktor et al. (2007) is discussed and we consider that these authors refer to G. benjaminus n. sp., and so we de…
Políticas de acceso abierto a la ciencia en las universidades españolas
2013
El objetivo del artículo es analizar el estado de la cuestión de las políticas en favor del acceso abierto (OA) a la ciencia en las universidades españolas. Para ello se han establecido cinco grandes mecanismos de intervención (la creación de infraestructuras y prestación de servicios, la comunicación y difusión, la incentivación económica, la coordinación institucional así como la reglamentación u obligación) que permiten llevar a cabo políticas a favor del acceso abierto y que hemos utilizado para el análisis y la valoración de la situación. La recogida de datos se ha basado en un cuestionario enviado a los vice-rectores de investigación y se ha complementado con la consulta de directorio…
Plan S: challenges and opportunities in Spain
2019
Spain is one of the most active European countries in the open access (OA) movement. Although the gold route has scarcely been used, the green route has been intensively implemented through fulfilment of European and national mandates and the development of institutional policies. Plan S is becoming a disruptive element in the context of scientific communication, and Spain’s possible adherence to Plan S could imply technical challenges in journals and repositories, additional costs that are difficult to estimate, or refusal to accept the Plan on the part of researchers (based on the loss of freedom to choose the journal in which to publish). However, the implementation of Plan S in Spain wo…
Nuevas vías de depósito, nuevos proyectos: consolidación del repositorio institucional RODERIC
2017
El objetivo de este artículo es dar a conocer los nuevos proyectos del repositorio institucional de la Universitat de València, RODERIC, así como las nuevas vías de depósito de documentos de investigación. Para ello, se analizan las distintas actuaciones dentro del apartado de investigación del repositorio. En primer lugar, las centradas en el área de revistas editadas en la UV, los proyectos sobre digitalización de tesis retrospectivas y publicación de tesis corrientes, y finalmente la integración del sistema CRIS con el repositorio. Se acaba con la descripción de una serie de mejoras que se prevén están disponibles en la segunda mitad de 2013. The aim of this paper is to present new proje…
Localización e identificación de las revistas universitarias para su integración en repositorios institucionales. El caso de la Universitat de Valènc…
2010
[EN] Objectives. Prior to starting up the University of Valencia's (UV) institutional repository, we assessed this institution's real output of periodical publications and drew up the most comprehensive list possible. We also described the visibility of the contents on the Internet. -- Method. We searched the ISSN database and the UV's library catalogue for journals in which the UV is included in the statement of responsibility. -- Results. These two sources did not provide sufficient information, as the University was not listed in all the relevant journals as a publishing entity. In total, 162 journals were found, of which 34.6% are still published. Many have been out of print since the 1…
Birds facing climate change: a qualitative model for the adaptive potential of migratory behaviour
2015
Recent climate change is altering the migratory behaviour of many bird species. An advancement in the timing of spring events and a shift in the geographical distribution have been detected for birds around the world. In particular, intra-Palearctic migratory birds have advanced arrivals in spring and shortened migratory distances by shifting northward their wintering grounds. These changes in migratory patterns are considered adaptive responses facilitating the adjustment of the life cycle to the phenological changes found in their breeding areas. However, in some cases, populations exposed to the same selective pressures do not show any appreciable adaptive change in their behaviour. Basi…
Adaptations and Predispositions of Different Middle European Arthropod Taxa (Collembola, Araneae, Chilopoda, Diplopoda) to Flooding and Drought Condi…
2012
Simple Summary This review summarizes adaptations and predispositions of different arthropod taxa (springtails, web spiders, millipedes and centipedes) to flood and drought conditions. The main focus sis directed to arthropod species, which are living in Middle European floodplain forests and wetlands, because of the fast change of flood and drought conditions in these habitats. Furthermore the effects of the predicted regional climate change like increasing aperiodic summer flooding and decreasing winter and spring floods are also discussed. Abstract Floodplain forests and wetlands are amongst the most diverse and species rich habitats on earth. Arthropods are a key group for the high dive…
Determinants and Congruence of Species Richness Patterns across Multiple Taxonomic Groups on a Regional Scale
2012
Applying multiple generalized regression models, we studied spatial patterns in species richness for different taxonomic groups (amphibians, reptiles, grasshoppers, plants, mosses) within the German federal state Rhineland-Palatinate (RP). We aimed (1) to detect their centres of richness, (2) to rate the influence of climatic and land-use parameters on spatial patterns, and (3) to test whether patterns are congruent between taxonomic groups in RP. Centres of species richness differed between taxonomic groups and overall richness was the highest in the valleys of large rivers and in different areas of southern RP. Climatic parameters strongly correlated with richness in all taxa whereas land…
Dissemination and national and international impact factors of spanish journals
2008
El artículo ofrece un estudio sobre las revistas científicas españolas vigentes. Se analizan datos sobre la antigüedad de las publicaciones, soporte documental, periodicidad, idiomas, difusión y visibilidad nacional e internacional. El propósito del trabajo ha sido realizar un análisis bibliométrico de las revistas científicas españolas que se editan actualmente. Se ha procedido a la consulta de diferentes directorios, repertorios y bases de datos bibliográficas. Se ha comprobado la veracidad de los datos recogidos consultando las páginas web de las revistas y a través del contacto con los editores de las publicaciones. Los resultados muestran que el comportamiento es desigual entre las rev…
Traditional Enterprise Business Intelligence Software Compared to Software as a Service Business Intelligence
2016
IntroductionBusiness Intelligence is a broad field of study. The major thrust of business intelligence theory analyzes certain factors to make highquality decisions. These factors include customers, competitors, business partners, economic environment and internal operations. Business Intelligence has the power to change the way people work, so that enterprises can compete more effectively and efficiently.A successful business intelligence solutions and successful implementation holds the key to the technological innovations together with the people, processes and culture of an organization to achieve a competitive and profitable BI strategy.Business Intelligence (BI) is the process of acqu…
