Relationship and correspondence between different impact indicators in a sample of articles of excellence
2016
The objective was to compare the impact factor to 2 years of self-citations (IF2Y) with impact factor 2 years without self-citations (IF2YWS) and IF2Y with the impact factor to 5 years (IF5Y) as well as IF2YWS with SCImago Journal Rank (SJR) about journals where they were published articles of excellence in smoking by Spanish authors in the period 2008-2012. The search was conducted in the SCI-E and the SSCI-E on November 25, 2013. Were selected documents that had the h index of the strategy global sample (number of articles that have at least that number of citations) to search using the descriptors "smok ∗" OR "tobac ∗". A total of 69 articles by Spanish authors were recovered from 55 jou…
Nemastoma bidentatum (Arachnida: Opiliones: Nemastomatidae): neu für Deutschland und die Tschechische Republik
2007
Nemastoma bidentatum (Arachnida: Opiliones: Nemastomatidae): first records for Germany and the Czech Republic. N. bidentatum Roewer, 1914 was found at two places in Germany: first on the island "Harriersand" in the Weser river (Lower Saxony), second on the banks of the river Elbe in the Elbsandsteingebirge (Saxony). Adjacent to the latter locality an occurrence in the Czech Republic could be located close to the German/Czech border in the floodplain of the river Elbe as well. These records are the first for Germany and the Czech Republic. They enlarge the distribution area of N. bidentatum remarkably in both a northern and a western direction. The two populations show conspicuous difference…
Patterns and dynamics of neutral lipid fatty acids in ants – implications for ecological studies
2017
Background Trophic interactions are a fundamental aspect of ecosystem functioning, but often difficult to observe directly. Several indirect techniques, such as fatty acid analysis, were developed to assess these interactions. Fatty acid profiles may indicate dietary differences, while individual fatty acids can be used as biomarkers. Ants are among the most important terrestrial animal groups, but little is known about their lipid metabolism, and no study so far used fatty acids to study their trophic ecology. We set up a feeding experiment with high- and low-fat food to elucidate patterns and dynamics of neutral lipid fatty acids (NLFAs) assimilation in ants. We asked whether dietary fatt…
Estratègies de formació i informació per implantar l'OpenCourseWare a la Universitat de València. Participació dels usuaris potencials en el procés

Biodiversity within the subfamily Alyssinae (Hymenoptera, Braconidae) in the Natural Park Peñas de Aya (Spain)
2011
Biodiversity within the subfamily Alyssinae (Hymenoptera, Braconidae) in the Natural Park Peñas de Aya (Spain). The study of parasitoid Hymenoptera is of significance for the assessment of diversity in a given area because of their role in the regulation of insects populations. The present work analyses diversity within Alysiinae (Hymenoptera, Braconidae) in the Forested Estate of Artikutza, located in the Natural Park Peñas de Aya, western Pyrenees, Spain. Collection of specimens was spread over two years and was carried out in two different habitats: mixed forest and beech forest. A total of 2,270 specimens, belonging to 22 separate genera, were captured. Subsequently, alpha, beta and gam…
Revision of the plant bug genus Xenocylapidius (Hemiptera, Heteroptera, Miridae, Cylapinae), with descriptions of five new species from Australia and…
2014
Abstract The genus Xenocylapidius Gorczyca, 1997 is revised. Five new species: Xenocylapidius acutipennis sp. n., Xenocylapidius ater sp. n., Xenocylapidius bimaculatus sp. n., Xenocylapidius gemellus sp. n., and Xenocylapidius rolandi sp. n. are described from Australia and New Caledonia. Illustrations of the male genitalia, color photographs of dorsal and lateral views of the adults of all species, and key to species of the genus Xenocylapidius are provided.
Check-list of Italian Birds, updated to the end of 2014
2015
We provide a check-list of Italian birds with major emphasis on the phenological categorization of each taxon, following the approach and updating the results of an analogous list previously published (Brichetti & Massa, 1998). In this list we based on the IOC World Bird List (Gill & Donsker, 2015) for nomenclature, species sequence and higher level taxonomy (from genus to order). This compilation takes into account the decisions made by the Italian Ornithological Commission (COI) and includes 548 species, recorded in Italy until the end of 2014.
An unidentified harvestman Leiobunum sp. alarmingly invading Europe (Arachnida: Opiliones)
2007
Etwa seit dem Jahr 2000 breitet sich eine bisher nicht identifizierte Art der Gattung Leiobunum C. L. Koch, 1839 schnell in Mitteleuropa aus. Nachweise ab dem Jahr 2004 sind aus den Niederlanden (wahrscheinlich dem Land des ersten Auftretens in Europa), Deutschland, Österreich und der Schweiz bekannt. Die wahrscheinlich eingeschleppte Art besiedelt bisher lediglich Wände von Gebäuden und seltener felsähnliche Biotope in Wäldern. Adulte Individuen ruhen tagsüber selten einzeln oder in eng geklumpten Gruppen aus Dutzenden bis Hunderten von Individuen an leicht abgedunkelten Stellen in Mauerwinkeln, an glatten Hauswänden und überhängenden Dachtraufen. Jungtiere leben am Boden. Diese Art verfüg…
Characterization of microbial communities in pest colonized books by molecular biology tools
2011
This work presents the identification of bacteria and fungi colonies in insect infesting books, by cultural-independent methodologies based on molecular biology techniques. Microbial genomic DNA extraction,<em> in vitro</em> amplification of specific target sequences by polymerase chain reactions (PCR), sequencing and sequence analysis were performed. These procedures minimized the samples amount, optimized the diagnostic studies on bacteria and fungi colonization and allowed the identification of many species also in complex microbial consortia. The molecular techniques for sure accomplish and integrate the microbiological standard methods (<em>in vitro</em>&nbs…
