    The paper analyses Spanish scientific journals today. It contains data on the age of the journals, their format, periodicity, languages, dissemination, and na-tional and international visibility.The objective of the paper is to carry out a biblio-metric analysis of the Spanish journals currently published. Different directories, re-pertoires and literature databases have been consulted. The veracity of the data collected has been checked by visiting the websites of the journals and by contacting their publishers. The results point to uneven behaviours across journals in different scientific disciplines. The most relevant finding is the constant growth in the number of Spanish journals in both national and international databases.The total number of Spanish journals published at present is 3004. The highest number of journals pu-blished in Spain is found in the Social Science area (42%), followed by Humanities (25%) and Medical Sciences (19%). As to their periodicity, most journals are an-nual. The most commonly used language is Spanish. Despite the growing trend of both national and international databases to include more and more Spanish scienti-fic journals, the number of Spanish journals included in the databases of the ISI Journal Citation Index (JCR of SCI and SSCI) remains low, with only 32 journals included in 2005 (1% approximately of the total journals currently published in Spain)

    INCISO: Automatic Elaboration of a Citation Index in Social Science Spanish Journals

    Citation indexes are key tools in the science communication system for two reasons. Firstly, they are an excellent information source for searching the scientific literature since they enable navigation through links between documents represented by bibliographic references. Secondly, they allow the evaluation of the scientific production. Citations count is a usual procedure to evaluate the quality of a research paper. In Spain, this evaluation can only be carried out using tools elaborated by the ISI which have a limited coverage of journals published outside Anglo – Saxon countries. In this way, the evaluation of the Spanish scientific production is limited to works published in international journals. There is no tool for the evaluation of research (mainly in Social Sciences and Humanities) published in local journals. With the INCISO research project we will investigate the possibility of create a citation index by automatic means. The deliverable of the project will be software to automatically create citation indexes and a sample citation index for social sciences.Ministerio de Educación y Ciencia.Proyecto de investigación HUM2004-05532Peer reviewe

    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 revistas de las diferentes disciplinas científicas. El da-to más relevante a destacar es que se observa un crecimiento constante en el número de revistas españolas que circulan en bases de datos, tanto nacionales como internacionales. El número total de revistas españolas que se editan actualmente es de 3004. El mayor número de revistas que se edita en España corresponde al área de Ciencias Sociales (42%), seguida de las correspondiente a las áreas de Humanidades (25%) y Ciencias Médicas (19%). La periodicidad más frecuente en las revistas españolas es la anual. El idioma más utilizado por las revistas es el español. Aunque se observa una tendencia de las bases de datos, tanto nacionales como internacionales, a incluir cada vez más un mayor número de revistas científicas españolas, el número de revistas españolas incluidas en las bases de datos Journal Citation Index (JCR del SCI y SSCI) del ISI, sigue siendo muy reducido, ya que en el año 2005 apenas supera el 1% ( 32 revistas) del número total de revistas que se editan actualmente en España.ABSTRACT: The paper analyses Spanish scientific journals today.

    Comparative study of stereoscopic techniques applied to a virtual globe

    Full text link
    [EN] For years, stereoscopy has been related to photogrammetry in topography. However, these methods are not efficient for virtual globes because the effect is only visible from one view point and this restricts interactivity. By using synthetic image techniques in order to generate stereo-paired images, we can produce visible effects from any view point. In this paper, we present a comparative study of stereoscopic techniques in virtual globes supported by a test carried out among 51 participants. Three devices were used: anaglyphs, an autostereoscopic screen and a quadbuffer system. The aim was to determine which one of the three devices causes a deeper feeling of immersion and which one can be more efficient in a virtual globe. Results show considerable differences between the quadbuffer system and the other devices. The mentioned system causes in the user a stronger feeling of depth and immersion in the virtual globe.This work receives funding from the CENIT project España Virtual (ref.

    Occupancy models reveal potential of conservation prioritization for Central American jaguars

    Understanding species-environment relationships at large spatial scales is required for the prioritization of conservation areas and the preservation of landscape connectivity for large carnivores. This endeavour is challenging for jaguars (Panthera onca), given their elusiveness, and the local nature of most jaguar studies, precluding extrapolation to larger areas. We developed an occupancy model using occurrence data of jaguars across five countries of Central America, collected from camera-trap studies of 2–12 months' duration, deployed over an area of 14 112 km 2 from 2005 to 2018. Our occupancy model showed that habitat use of jaguars increased with primary net productivity and distance to human settlements, and decreased with distance to rivers. Detection of the species was related to survey effort and research team identity. Within the jaguar extent of occurrence, 73% was deemed suitable for the species, with 47% of it lying within Jaguar Conservation Units (JCU) and 59% of JCU land being legally protected. Suitable areas were divided into four distinct clusters of continuous habitat shared across country borders. However, large areas of predicted low habitat suitability may constrict connectivity in the region. The reliability of these spatial predictions is indicated by the model validation using an independent dataset (AUC = 0.82; sensitivity = 0.766, specificity = 0.761), and concordance of our results with other studies conducted in the region. Across Central America, we found that human influence has the strongest impact on jaguar habitat use and JCUs are the main reservoirs of habitat. Therefore, conservation actions must focus on preventing habitat loss and mitigating human pressure, particularly within the clusters of continuous areas of high suitability, and on restoring habitat to foster connectivity. The long-term persistence of jaguars in the region will depend on strong international cooperation that secures jaguar populations and their habitat across Central American borders. </p

    Has taxonomic vandalism gone too far? A case study, the rise of the pay-to-publish model and the pitfalls of Morchella systematics

    The genus Morchella has gone through turbulent taxonomic treatments. Although significant progress in Morchella systematics has been achieved in the past decade, several problems remain unresolved and taxonomy in the genus is still in flux. In late 2019, a paper published in the open-access journal Scientific Reports raised serious concerns about the taxonomic stability of the genus, but also about the future of academic publishing. The paper, entitled “High diversity of Morchella and a novel lineage of the esculenta clade from the north Qinling Mountains revealed by GCPSR-based study” by Phanpadith and colleagues, suffered from gross methodological errors, included false results and artifactual phylogenies, had misapplied citations throughout, and proposed a new species name invalidly. Although the paper was eventually retracted by Scientific Reports in 2021, the fact that such an overtly flawed and scientifically unsound paper was published in a high-ranked Q1 journal raises alarming questions about quality controls and safekeeping procedures in scholarly publishing. Using this paper as a case study, we provide a critical review on the pitfalls of Morchella systematics followed by a series of recommendations for the delimitation of species, description of taxa, and ultimately for a sustainable taxonomy in Morchella. Problems and loopholes in the academic publishing system are also identified and discussed, and additional quality controls in the pre- and post-publication stages are proposed
