Rooting and acclimatization of micropropagatedHypericum perforatumL. native to Sicily
2017
Hypericum perforatum L. is traditionally used as a medicinal plant because of its different bioactive compounds with documented antidepressant and antiinflammatory activities. Plantlets’ mass production with high content of these secondary metabolites has been enhanced through in vitro culture but the process has often been stopped at the multiplication phase. A study was conducted in order to set up an efficient in vitro rooting and acclimatization protocol of a H. perforatum Sicilian genotype well-adapted to south Mediterranean conditions. Aseptic nodal segments were cultured onto a Murashige and Skoog (MS) basal medium supplemented with 4.44 µM 6-benzyladenine for multiplication. Microsh…
The cost of open access publication of papers by spanish authors in five areas of the social sciences
2021
[ES] La publicación en abierto de los artículos conlleva unos gastos conocidos como cargos por procesamiento de artículos (APC, en sus siglas en inglés). El objetivo de este trabajo es determinar el coste de los artículos publicados en abierto mediante APC de autoría española en cinco categorías temáticas de las ciencias sociales: Humanities (Multidisciplinary), Sociology, Information Science & Library Science, Education & Educational Research y Communication de la Colección Principal de la Web of Science (WoS) durante el periodo 2012-2019. Se han identificado las revistas, las instituciones financiadoras y los modelos de publicación más frecuentes. El estudio indica que de las 223 revistas…
Bryophyte Species Richness on Retention Aspens Recovers in Time but Community Structure Does Not
2014
Green-tree retention is a forest management method in which some living trees are left on a logged area. The aim is to offer ‘lifeboats’ to support species immediately after logging and to provide microhabitats during and after forest re-establishment. Several studies have shown immediate decline in bryophyte diversity after retention logging and thus questioned the effectiveness of this method, but longer term studies are lacking. Here we studied the epiphytic bryophytes on European aspen (Populus tremula L.) retention trees along a 30-year chronosequence. We compared the bryophyte flora of 102 ‘retention aspens’ on 14 differently aged retention sites with 102 ‘conservation aspens’ on 14 d…
Preface: Emerging trends in aquatic ecology II
2017
You are now consulting the celebratory volume 750 of Hydrobiologia, the international journal of aquatic sciences. The journal has, since its first volume in March 1948, now exactly 67 years ago, covered a lot of ground and has seen a lot of change in the landscape of scientific publishing in general, and in that of aquatic biodiversity in particular. It has evolved from a fairly locally managed journal, to an international journal with ever increasing impact and ranking. With an ISI 2013 Impact Factor of 2.212, it now ranks 32 out of 103 journals in ‘‘Marine and Freshwater Biology’’. But in the ‘‘Marine Sciences and Fisheries’’ Category of Google Scholar, Hydrobiologia ranks proudly at a 9…
Diet and trophic niche of the invasive signal crayfish in the first invaded Italian stream ecosystem.
2021
The occurrence of the signal crayfsh Pacifastacus leniusculus in the Valla Stream was the frst established population of this invasive species recorded in an Italian stream ecosystem. We evaluated the seasonality of diet and trophic niche of invasive signal crayfsh in order to estimate the ecological role and efects on native communities of the stream ecosystem. We studied the diferences in food source use between sexes, life stages and seasons using carbon and nitrogen stable isotope analyses. To supplement stable isotope analyses, we evaluated food source usage using traditional stomach content analysis. We tested the hypothesis that juveniles have a diferent diet, showing diferent trophi…
Plant invasions on small Mediterranean islands. An overview
2016
Biological invasions have become one of the main drivers of habitat degradation and a leading cause of biodiversity loss in island ecosystems worldwide. The spread of invasive species poses a particular environmental threat on the islands of the Mediterranean Basin, which are hot spots of biodiversity and contain rare habitats and endemic species, especially on small islands, which are highly vulnerable to biodiversity loss. Following a recent survey, in this paper we aim to provide an overview of the present-day non-native vascular flora of small Mediterranean islands based on a sample of 37 islands located in the middle of the Mediterranean Sea, off the coast of Italy. By comparing the cu…
Atlas of Finnish bats
2019
This atlas is based on information in museum collections, literature, databases and unpublished data. In the last 150 years, the number of bat species in Finland increased from six to thirteen. Of these, five are common and regularly breeding (Eptesicus nilssonii, Myotis brandtii, Myotis daubentonii, Myotis mystacinus, Plecotus auritus), and eight rare (Eptesicus serotinus, Myotis dasycneme, Myotis nattereri, Nyctalus noctula, Pipistrellus nathusii, Pipistrellus pipistrellus, Pipistrellus pygmaeus, Vespertilio murinus), of which breeding of two (M. nattereri, P. nathusii) have been confirmed. The total number of records in the study is 11 234, of which 9717 are identified to species. The re…
How Long Is Too Long in Contemporary Peer Review? Perspectives from Authors Publishing in Conservation Biology Journals
2015
Delays in peer reviewed publication may have consequences for both assessment of scientific prowess in academics as well as communication of important information to the knowledge receptor community. We present an analysis on the perspectives of authors publishing in conservation biology journals regarding their opinions on the importance of speed in peer-review as well as how to improve review times. Authors were invited to take part in an online questionnaire, of which the data was subjected to both qualitative (open coding, categorizing) and quantitative analyses (generalized linear models). We received 637 responses to a total of 6,547 e-mail invitations sent. Peer-review speed was gene…
Dispersal flight and colony development in the fungus-growing termites Pseudacanthotermes spiniger and P. militaris
2012
International audience; Pseudacanthotermes spiniger and P. militaris are two African fungus-growing termites (Termitidae, Macrotermitinae) which may become pests in disturbed agrosystems where they often live in sympatry. To study their development and their reproductive strategies, colonies of both species were reared in the laboratory for 20 and 17 years, respectively, after their foundation from reproductive pairs. The first steps of development were in great part similar in both species, although P. spiniger favoured the defence during the juvenile period, while P. militaris tended to favour a rapid development. While P. spiniger colonies did not produce alates until year 7 of colony li…
