Spanish scientific production in literature through a gender perspective in the Web of Science (1975-2017)
2019
[ES]: Se realiza un estudio comparativo desagregado por sexos de la producción científica en literatura de los investigadores que trabajan en instituciones españolas. Se han identificado 806 autores que han publicado algún trabajo de literatura en revistas indexadas en la WoS hasta el año 2017, analizando comparativamente su productividad y patrones de colaboración considerando la variable sexo. El 55.51 % de los autores identificados fueron hombres frente a un 44.49 % de mujeres. Los resultados muestran que entre los grandes productores del ámbito de la literatura predominan los hombres. Entre los productores moderados (2-5 trabajos), el 50.36 % de los autores identificados fueron hombres …
Effects of migratory status and habitat on the prevalence and intensity of infection by haemoparasites in passerines in eastern Spain
2013
Efectos del estatus migratorio y del tipo de habitat sobre la prevalencia y la intensidad de la infeccion por hemoparasitos en paseriformes en el este de Espana La peninsula iberica es un sitio idoneo para estudiar los efectos de la condicion migratoria en la prevalencia de hemoparasitos en comunidades de aves, dado que convergen poblaciones residentes locales con especies migratorias y abundantes poblaciones de vectores. En este trabajo examinamos la incidencia de hemoparasitos presentes en aves de tres localidades de la region mediterranea (este de Espana), con respecto del estatus migratorio. Examinamos 333 frotis sanguineos de 11 especies, y encontramos una prevalencia global del 9,6%. …

Differentiation of Trichuris species eggs from non-human primates by geometric morphometric analysis
2020
Human trichuriasis is a neglected tropical disease which affects millions of people worldwide, mostly living in low socio-economic conditions. Numerous studies have been conducted over the past 10 years to compare the different techniques for T. trichiura eggs detection. Our study provides the first geometric morphometric analysis for the specific detection of eggs of Trichuris sp. isolated from stools of macaque (M. sylvanus), colobus (C. g. kikuyensis), grivets (C. aethiops) and the Brazza's monkey (C. neglectus) from zoos in Spain. Principal Component Analysis (PCA) arises as an efficient method to determine Trichuris spp. eggs. The selected measurements to be included in the PCA were pr…
Análisis del proceso de internacionalización de la investigación española en ciencia y tecnología (1980-2007)
2012
The process of scientific internationalization in Spain is based on an analysis of the growth of scientific publications and the evolution of international collaboration in Spanish scientific papers indexed in the Science Citation Index-Expanded database between 1980 and 2007. The article examines science policies in Spain together with the investments in economic and human resources devoted to research, and their effects on the internationalization process. Scholarly research in Spain has become increasingly international over the last three decades. The main features of this process have been a linear growth of productivity in terms of the number of papers published per year; a progressiv…
New corological and biological data of the Red Gum Lerp Psyllid, Glycaspis brimblecombei Moore, 1964 in Italy (Hemiptera, Psyllidae)
2011
Glycaspis brimblecombei Moore, 1964 is a psyllid (Hemiptera: Psyllidae) pest of Eucalyptus, native toAustralia and first recorded in Europe: Spain in 2008 and more recently (2010) in Italy. The present paper dealswith recent research, carried out in central Italy, with new data on the distribution and biology of this species.
Two new African and Madagascan species of the genus Holochlora (Orthoptera: Tettigoniidae, Phaneropterinae)
2017
Two new species, Holochlora mauritiana and H. ingrischi from the island of Mauritius and Zimbabwe, respectively, are described. Along with a third species, H. biloba Stål, 1874 from Madagascar, they are the sole African representatives of the mostly Oriental genus Holochlora Stål, 1873, including ca. 60 taxa distributed from India to China. Preliminary hypotheses on biogeographical and evolutionary origin of Afro-Madagascan Holochlora species are shortly discussed.
