Climate warming is expected to increase growth and expansion of evergreen vegetation in many cold regions, with substantial influences on ecological and atmospheric processes. Nevertheless, the direction and magnitude of changes in productivity (greenness) of evergreen vegetation, as well as their potential drivers, remain unclear in many parts of the world. [...]

9 p, 565.7 KB "Our city will be the first to hold both summer and winter olympics" : a comparative analysis of how media coverage and public opinion were framed on social media in the lead up to the Beijing 2022 winter Olympic games / Yang, Zesheng (Universitat Autònoma de Barcelona. Departament de Comunicació Audiovisual i Publicitat) ; Ruan, Yang ; Zhang, Jianing (Macau University of Science and Technology)
Beijing is the first city to host both the Summer and Winter Olympic Games. Mega sporting events such as the Olympic Games, which attract mass audiences, benefit greatly from social media. This article examines how the news coverage and public opinion about the Beijing 2022 were articulated on social media in the lead up to the Beijing 2022. [...]

18 p, 721.7 KB Foliar photochemical processes and carbon metabolism under favourable and adverse winter conditions in a Mediterranean mixed forest, Catalonia (Spain) / Sperlich, Dominik (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Chang, C. T. (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Gracia, Carles (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental conditions above the threshold for a positive carbon balance, benefitting evergreen woody species more than deciduous ones.

35 p, 523.6 KB Alteration of the phenology of leaf senescence and fall in winter deciduous species by climate change: effects on nutrient proficiency / Estiarte, Marc (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Leaf senescence in winter deciduous species signals the transition from the active to the dormant stage. The purpose of leaf senescence is the recovery of nutrients before the leaves fall. Photoperiod and temperature are the main cues controlling leaf senescence in winter deciduous species, with water stress imposing an additional influence. [...]

17 p, 380.8 KB Una breu ullada als Jocs Olímpics d'hivern / Chappelet, Jean-Loup
Des de 1924, uns Jocs realitzats durant els mesos hivernals i reservats als esports que es practiquen sobre la neu o el gel complementen els Jocs Olímpics d'Estiu. Els Jocs d'Hivern tenen una dimensió molt menor que els Jocs d'Estiu. [...]

14 p, 1.3 MB Desenvolupament d'una xarxa social per a esports d'hivern : SocialSKI / Balagué Ferrer, Josep Oriol ; Bartrina Rapesta, Joan, dir. (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Universitat Autònoma de Barcelona. Escola d'Enginyeria
Aquest projecte és la continuació del desenvolupament de la xarxa social per a esports d'hivern que va començar el Juny del 2016. En la primera versió de SocialSKI es va desenvolupar una demo només per a dispositius mòbils, fent-ne ús, els usuaris podien accedir mitjançant diferents plataformes per tal de conèixer l'estat actual de les pistes d'esquí així com les dades meteorològiques de les estacions i les opinions que els mateixos usuaris aportaven a la aplicació sobre diferents aspectes referents a les pistes d'esquí. [...]
This project is the continuation of the development of a winter sports oriented social network that began in June 2016. The first version of SocialSKI was a demo developed for mobile devices. Using SocialSKI, users could access trough different platforms to data referring to the state of the ski slopes, the meteorological conditions in the different stations and the opinions referring to the state of the ski slopes submitted by the users of the social network.
