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.

Se analiza el comportamiento fitosociológico de las comunidades vegetales caracterizadas por la presencia de los taxones Cheilanthes tinaei Todaro y Ch. hispanica Mett. en el Sector Orensano-Sanabriense (Provincia Carpetano-lbérico-Leonesa), proponiendo para ellas la asociación Linario glabrescentis-Cheilanthetum tinaei y las subasociaciones: Linario glabrescentis-Cheilanthetum tinaei cheilanthetosum hispanicae nova y Linario glabrescentis-Cheilanthetum tinaei cheilanthetosum guanchicae nova.Comentamos brevemente la asociación Phagnalo saxatile-Rumicetum indurati Rivas-Martínez inéd, que contacta topográficamente con la asociación anteriormente propuesta.Se aportan datos sobre el comportamiento fitosociológico de Cheilanthes pteridioides (Reichard) C. Chr.

En el presente trabajo se ha realizado una revisión del género Seseli L. en la Península Ibérica: en él se incluye una clave para la determinación de los táxones existentes, así como un mapa corológico de los mismos y las localidades estudiadas, pliegos y herbarios consultados. Se proponen dos combinaciones nuevas, S. granatense Will. por S. montanum L. subsp. granatense (Will.) Pardo y S. varyredanum Font Quer por Athamanta vayredana (Font Quer) Pardo, teniendo en cuenta tanto los caracteres morfológicos de la planta como los polínicos y anatómicos de los mericarpos (Pardo inéd.). En el presente trabajo no se incluye el taxon S. farrenyi Molero & Pujadas, debido a que esta nueva especie fue publicada con posterioridad a la realización de nuestro estudio.

As a continuation of previous research on the naturalization of non-native vascular plants in the Iberian Peninsula new chorological data are presented for 16 xenophytes recorded between 2010 and 2014, mostly in the provinces of Huelva and Barcelona (Spain) and in the Algarve and Estremadura (Portugal). For each taxon details about distribution, habitats occupied, previous records, degree of naturalization, etc. are provided. Lachenalia bulbifera and Cyperus albostriatus are probably reported for the first time in the wild in Europe, as are Gamochaeta filaginea, and Dysphania anthelmintica and Oenothera lindheimeri for Portugal and Spain respectively. Cosmos bipinnatus is cited as a novelty for the Algarve (Portugal). Newly reported or confirmed for the province of Huelva are: Amaranthus hypochondriacus, Epilobium brachycarpum, Nephrolepis cordifolia, Ficus microcarpa, Tamarix parviflora and Tamarix ramosissima, while Atriplex semibaccata, Chloris truncata, and Elymus elongatus subsp. ponticus are new for Barcelona. Finally, Passiflora caerulea is a novelty for both Barcelona and Huelva provinces.

Studies on the flora and fauna of the Canary Islands show that this Archipelago is one of the planet’s diversity hot spots. However, an analysis of the differences in the phytogeographic characteristics of each of the islands that make up this Archipelago is lacking. This article focuses on the phytogeographic characterization of the island of Gran Canaria. This island exhibits geological and climatic characteristics resulting in a rich vascular flora, including endemic species and genera that are significantly different from the other islands of the Archipelago. These differences are verified through statistical analysis of the existing similarity between the floras of the members of the Canary Islands. This study also analyses the subdivision of Gran Canaria Island, indicating that there are three well-differentiated areas on the island itself. Finally, this study argues that these areas, themselves, should be considered biogeographic sectors.

Measures of prevention and control against polycyclic aromatic hydrocarbons (PAHs) focus on an official food control, a code of best practice to reduce PAHs levels by controlling industry and in the development of a chemopreventive strategy. Regulation (EU) 835/2011 establishes maximum levels of PAHs for each food group. In addition, Regulations (EU) 333/2007 and 836/2011 set up the methods of sampling and analysis for its official control. Scientific studies prove that the chemopreventive strategy is effective against these genotoxic compounds effects. Most chemopreventive compounds studied with proven protective effects against PAHs are found in fruit and vegetables.

This article aims to propose a chronological subdivision in the history of African communication. African communication today is one of the most important axes for implementing development strategies, sustaining education, health, and schooling programmes, and so on. However, many of these programmes fail due to a lack of or ineffective communication between international organisations, local elite and lay people. The reasons for this situation must be found in Africa’s history of communication, which has undergone radical transformations in its different phases. Using the functionalist analysis drawn up by Jakobson, this article proposes a new chronological subdivision of Africa’s history of communication, reflecting on the current contradictions in contemporary communication in Africa.

En este artículo analizamos la valoración de los titulados universitarios sobre la formación recibida y su utilidad en la ocupación actual. El objetivo es analizar si existen diferencias por el nivel formativo de origen y el sexo de los estudiantes. A su vez, examinamos si las características de la situación laboral intervienen en estas relaciones afectando diferencialmente según las características sociodemográficas. Los resultados muestran la existencia de diferencias valorativas entre los jóvenes según su origen social y sexo, siendo las mujeres y los jóvenes de clase trabajadora los que valoran mejor su formación recibida. Finalmente, con la introducción de la situación laboral como variable de control constatamos que, en algunos casos, estas diferencias valorativas son debidas al contexto laboral actual de los graduados más que a diferencias sociodemográficas.
