This article studies and reproduces a group of documents that includes some hand-written and typed texts most likely authored by Rubén Darío, along with others where Darío’s authorship can be easily contested. These documents seem to have originated during the years of Mundial Magazine (1912-1914), and besides the interest for their probably unpublished nature, they also show the cooperation between Darío and his collaborators in the preparation of his original manuscripts right before being sent to the publishers.

Information on 12 exotic plants of diverse interest for the Galician flora are presented. All of them were collected in Ribeira council (SW of the A Coruña province). The total includes 8 novelties at a regional level (Aeonium haworthii, Aloe mitriformis, Brugmansia × candida, Nephrolepis cordifolia, Osteospermum ecklonis, Pelargonium capitatum, Sedum mexicanum, Sparaxis tricolor), and 2 provincial novelties. In addition, information on two taxa hardly mentioned in the literature on Galician vascular flora is also included. All the cited specimens are deposited at the SANT Herbarium.

Sandy shores are known to be extreme ecosystems where the vegetation has evolved many morphological and physiological adaptations for its survival. With the aim of identify possible relationships between the vegetation´s functional diversity with abiotic factors and its corresponding quantification, we collected data on the abundance and richness of the sandy coast vegetation complex in Grande, Anclitas and Caguamas keys. Its flora is largely characterized by the dominance of hemicryptophytes and chamaephytes plants with nanophyllous leaves and displaying dispersal syndromes such as zoochory and anemochory. However, the functional groups´ richness, in the present study, varies from one key to another. Functional diversity is similar between the wet and dry seasons, and its spatial variation is influenced by the interplay of the set of abiotic factors herein studied.

En este artículo se describen varias comunidades de plantas en Gran Canaria, especialmente las procedentes de playas y otros lugares de la zona SE de la isla. También se hacen comentarios sobre la presencia reciente de alguna especie hasta el momento no registrada en el territorio recorrido, como Limnoniastrum monopetalum. Se estudian algunas asociaciones nitrófilas y otras de los depósitos arenosos de la desembocadura de la rambla de Jinamar. También la expansión de alguna especie de acacias en las dunas de Maspalomas. Se da a conocer una nueva asociación cerca de la playa de San Agustín: A triplici-Amaranthetum gracilis, muy extendida por la zona estudiada.

We present descriptions of a new order (Ranunculo cortusifolii-Geranietalia reuteri and of a new alliance (Stachyo lusitanicae-Cheirolophion sempervirentis) for the herbaceous fringe communities of Macaronesia and of the southwestern Iberian Peninsula, respectively. A new alliance, the Polygalo mediterraneae-Bromion erecti (mesophilous post-cultural grasslands), was introduced for the Peninsular Italy. We further validate and typify the Armerietalia rumelicae (perennial grasslands supported by nutrient-poor on siliceous bedrocks at altitudes characterized by the submediterranean climate of central-southern Balkan Peninsula), the Securigero-Dasypyrion villosae (lawn and fallow-land tall-grass annual vegetation of Italy), and the Cirsio vallis-demoni-Nardion (acidophilous grasslands on siliceous substrates of the Southern Italy). Nomenclatural issues (validity, legitimacy, synonymy, formal corrections) have been discussed and clarified for the following names: Brachypodio-Brometalia, Bromo pannonici-Festucion csikhegyensis, Corynephoro-Plantaginion radicatae, Heleochloion, Hieracio-Plantaginion radicatae, Nardetea strictae, Nardetalia strictae, Nardo-Callunetea, Nardo-Galion saxatilis, Oligo-Bromion, Paspalo-Heleochloetalia, Plantagini-Corynephorion and Scorzoneret alia villosae.

This article reflects on the changing environment through the passage of time and how certain technologies for a creative proposal allow the preservation and transmission of a significant part of that ephemeral heritage for future generations. The general purpose of this particular project is aimed to achieve the sound synthesis of a specific and representative cityscape as the old train station in Cuenca –located in the heart of the city– that could be preserved and reproduced as an unique document of a present time, ascertainable in the future: a memory that interpret sound as a time capsule. This soundscape was made to mark the arrival of the high speed train in 2010 to a brand new station in the outskirts of the city. Therefore, the goal of this research was focused on achieving a synthetic document that provided a sound memory capable of reflecting the significant social, cultural and logistical features, of what was until then the only railway communication symbol in the city of Cuenca from 1883 to the first decade of the 21st century.

La gráfica se encuentra en un proceso de simbiosis con la cultura visual en el que la tecnología de la imagen, la descentralización de la matriz y la adaptación del formato expositivo se funden con el resto de las actividades artísticas. El análisis de las comunidades formadas alrededor de esta práctica configura un puzzle, aparentemente bien encajado, que se divide entre el formalismo y el conceptualismo y entre la idea y el proceso. Las bienales y trienales, a la vanguardia del discurso, cuestionan cualquier concepto que se haya podido asentar con solidez: ante la decadencia del proceso artesanal el mensaje se profundiza nutriéndose de la invectiva provocada por las contradicciones sociales, territoriales y medioambientales para convertirse en un reflejo de la sociedad contemporánea. Comprender la gráfica actual pasa por un ejercicio de aperturismo y un proceso de adaptación al cambio técnico e iconográfico de los sectores implicados. El grabado es ahora un territorio en el que la integración de todas las artes permite cruzar sus fronteras con fluidez.
