Comparison of different methods to assess the distribution of alien plants along the road network and use of Google Street View panoramas interpretat…
2021
The survey by foot in the field is compared to the survey from a car, the photo-interpretation of Google Street View (GSV) panoramas continuously and at intervals of 1.5 km and the photo-interpretation of Google Earth aerial images on a 10 km stretch of road in Sicily. The survey by foot was used as reference for the other methods. The interpretation of continuous GSV panoramas gave similar results as the assessment by car in terms of the number of species identified and their location, but with lower cost. The interpretation online of aerial photos allowed the identification of a limited number of taxa, but gave a good localisation for them. Interpretation of GSV panoramas, each of 1.5 km,…

Classification of the European marsh vegetation (Phragmito‐Magnocaricetea) to the association level
2020
Aims: To create a comprehensive, consistent and unequivocal phytosociological classification of European marsh vegetation of the class Phragmito-Magnocaricetea. Location: Europe. Methods: We applied the Cocktail method to a European data set of 249, 800 vegetation plots. We identified the main purposes and attributes on which to base the classification, defined assignment rules for vegetation plots, and prepared formal definitions for all the associations, alliances and orders of the class Phragmito-Magnocaricetea using formal logic. Each formula consists of the combination of “functional species groups”, cover values of individual species, and in the case of high-rank syntaxa also of “disc…
Action Programs for Rhynchophorus ferrugineus and Paysandisia archon
2017
The spread of invasive alien species is strongly associated with the rapid acceleration of human trade, tourism, transport, and travel over the past century, which have allowed these species to overcome natural geographic barriers. The best strategy to prevent the spread of invasive species is quarantine and eradication of initial foci. However, when invasive species appear to be established, the best approach should focus on containment and decreasing their impact through specific control measures. In this context, considering the rapid spread of the two palm pest species recently introduced in the Mediterranean area-Rhynchophorus ferrugineus (red palm weevil, RPW) and Paysandisia archon (…
Covariation in population trends and demography reveals targets for conservation action
2021
Wildlife conservation policies directed at common and widespread, but declining, species are difficult to design and implement effectively, as multiple environmental changes are likely to contribute to population declines. Conservation actions ultimately aim to influence demographic rates, but targeting actions towards feasible improvements in these is challenging in widespread species with ranges that encompass a wide range of environmental conditions. Across Europe, sharp declines in the abundance of migratory landbirds have driven international calls for action, but actions that could feasibly contribute to population recovery have yet to be identified. Targeted actions to improve condit…
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…
Bioethics and neuroethics
2019
Neuroethics officially appeared at the start of the 21st century due to the progress made by the neurosciences, as an applied ethics related to bioethics, but also as an independent discipline in its own right. As an applied ethics, it tackles issues bordering on bioethics. As independent neuroethics, it deals with established philosophical problems from a neuroscientific standpoint in the broader sense. It involves two central questions: the design of a framework in which to select, interpret and integrate data from neuroscience on morality and outlining the appropriate method or methods for this new branch of knowledge. In both cases, most neuroethicists curiously claim to take a naturali…
Climate change and the ecology and evolution of Arctic vertebrates
2012
Climate change is taking place more rapidly and severely in the Arctic than anywhere on the globe, exposing Arctic vertebrates to a host of impacts. Changes in the cryosphere dominate the physical changes that already affect these animals, but increasing air temperatures, changes in precipitation, and ocean acidification will also affect Arctic ecosystems in the future. Adaptation via natural selection is problematic in such a rapidly changing environment. Adjustment via phenotypic plasticity is therefore likely to dominate Arctic vertebrate responses in the short term, and many such adjustments have already been documented. Changes in phenology and range will occur for most species but wil…
Simple learning rules to cope with changing environments
2008
10 pages; International audience; We consider an agent that must choose repeatedly among several actions. Each action has a certain probability of giving the agent an energy reward, and costs may be associated with switching between actions. The agent does not know which action has the highest reward probability, and the probabilities change randomly over time. We study two learning rules that have been widely used to model decision-making processes in animals-one deterministic and the other stochastic. In particular, we examine the influence of the rules' 'learning rate' on the agent's energy gain. We compare the performance of each rule with the best performance attainable when the agent …
