2020

Este artículo se encuentra disponible a texto completo en la siguiente URL: https://revistas.uam.es/tendenciaspedagogicas/article/view/tp2020_36_09 Este número monográfico de la revista Tendencias Pedagógicas lleva por título "La alfabetización académica". Este trabajo pretende reflexionar sobre las implicaciones educativas que hoy día tiene la competencia mediática en los procesos de enseñanza-aprendizaje. La evolución de las TIC y, sobre todo, de la tecnología móvil, ha provocado una revolución comunicativa educativa y social que afecta al mundo educativo; los contextos edu-cativos son cambiantes y evolucionan rápido, teniendo que adaptarse a los cambios socioculturales, tecnológi-cos, et…

Gill area explains deviations from body size–metabolic rate relationship in teleost fishes

2022

Whether gill area constrains fish metabolism through oxygen limitation is a debated topic. Here, the authors provide insights into this question by analysing mass-specific metabolic rates across 44 teleost fishes extracted from FishBase. They explore whether species deviations from metabolic rates predicted by body mass can be explained by species gill area. They show that the gill area explains c. 26%–28% of species-level deviations from mass-specific metabolic rates. Their findings suggest that gill area might indeed be one of the factors limiting metabolic rate in fishes.

Prenatal thyroid hormones accelerate postnatal growth and telomere shortening in wild great tits

2021

AbstractEarly-life environment is known to affect later-life health and disease, which could be mediated by the early-life programming of telomere length, a key hallmark of ageing. According to thefetal programming of telomere biology hypothesis, variation in prenatal exposure to hormones is likely to influence telomere length. Yet the contribution of key metabolic hormones,i.e. thyroid hormones (THs), has been largely ignored. We recently showed that in contrast to predictions, exposure to elevated prenatal THs increased postnatal telomere length in wild collared flycatchers, but the generality of such effect, its underlying proximate mechanisms and consequences on survival have not been i…

Atmospheric brightening counteracts warming‐induced delays in autumn phenology of temperate trees in Europe

2021

Aim: Ongoing climate warming has been widely reported to delay autumn phenology, which in turn impacts carbon, water, energy and nutrient balances at regional and global scales. However, the underlying mechanisms of autumn phenology responses to climate change have not been fully elucidated. The aims of this study were to determine whether brightening that was defined as the increase of surface solar radiation and warming during recent decades affect autumn phenology in opposite directions and explore the underlying mechanisms. Location: Central Europe. Time period: 1950–2016. Major taxa studied: Four dominant European tree species in central Europe: Aesculus hippocastanum, Betula pendula, …

Filipinas en el marco del imperio español en el siglo XIX

2019

[EN] En este artículo se analiza la evolución de Filipinas en las últimas décadas del siglo XVIII y en el transcurso del siglo XIX a través de diferentes epígrafes: la obligada transformación del secular modelo colonial volcado hacia el tráfico del Galeón y las relaciones transpacíficas; la renovada inclinación hacia Asia, el océano Índico y el mar de China; el desarrollo de un sistema económico basado en la exportación de productos filipinos y en la apertura de las islas al exterior; la evolución de la vida política; el camino hacia la modernización; el peso de las órdenes religiosas, la importancia de la población china y la colaboración con élites indígenas como rasgos singulares de Fili…

Red list of threatened vascular plants in Italy

2021

Italy has a rich natural heritage, which is dangerously under pressure. In recent years, there is an increased awareness of the crucial role of plants in ecosystem functioning and in providing ecosystem services. Consequently, an updated Red List of the Italian vascular flora was compiled in this work, at the request of the Ministry for Environment, Land and Sea Protection, with the scientific support of the Italian Botanical Society. The IUCN Red List criteria were applied to 2,430 Italian native vascular plant taxa to assess their current extinction risk and to highlight the major threats affecting the Italian flora. Our results revealed that 54 taxa (2.2% of the assessed taxa) are extinc…

IDPlanT: the Italian database of plant translocation

2021

IDPlanT is the Italian Database of Plant Translocation, an initiative of the Nature Conservation Working Group of the Italian Botanical Society. IDPlanT currently includes 185 plant translocations. The establishment of a national database on plant translocation is a key step forward in data sharing and techniques improvement in this field of plant conservation. Supplemental data for this article is available online at https://doi.org/10.1080/11263504.2021.1985004.

ISEBA – A Framework for IS Evolution Benefit Assessment

2005

Decisions regarding information system evolution strategy, including modernization or replacement, are economically significant. Selection of a proper method for analyzing potential options, acquisition of suitable metrics or follow-up data, and evaluation of the results are major challenges in the evolution strategy decision making. In order to address these challenges, a framework for Information System Evolution Benefit Assessment (ISEBA) was developed. ISEBA provides assistance in the selection of a benefit-evaluation method for the investment situation at hand. It is based on empirical research on industrial decision making and co-operation projects, and examination of existing researc…
