Spatial patterns and trends in abundance of larval sandeels in the North Sea: 1950-2005

Early recruitment indices based on larval fish data from the Continuous Plankton Recorder (CPR) have the potential to inform stock assessments of Ammodytes marinus in the North Sea. We evaluate whether the CPR data are reliable for sandeel larvae. Spatially, CPR larval data were comparable with catches by dedicated larval samplers (Gulf and bongo nets) during ICES coordinated surveys in 2004 and 2009. ICES data are also used to explore environmental influences on sandeel distributions. Temporally, CPR data correlate with larval data from plankton surveys off Stonehaven (1999–2005), with sandeel 0-group trawl data at the east Fair Isle ground (since 1984), and with recruitment data (since 1983) for the Dogger Banks stock assessment area. Therefore, CPR data may provide an early recruit index of relative abundance for the Dogger Banks assessment area, where the majority of the commercial catch of A. marinus is taken, and the Wee Bankie area that is particularly important for seabird foraging. While warm conditions may stimulate the production of sandeel larvae, their natural mortality is typically greater, in the Dogger Banks and Wadden Sea areas, when the larvae are hatched in warm years and/or with abundant 1-year-old sandeel that are likely to be cannibalistic.

Developments since 2005 in understanding potential environmental impacts of CO2 leakage from geological storage

This paper reviews research into the potential environmental impacts of leakage from geological storage of CO2 since the publication of the IPCC Special Report on Carbon Dioxide Capture and Storage in 2005. Possible impacts are considered on onshore (including drinking water aquifers) and offshore ecosystems. The review does not consider direct impacts on man or other land animals from elevated atmospheric CO2 levels. Improvements in our understanding of the potential impacts have come directly from CO2 storage research but have also benefitted from studies of ocean acidification and other impacts on aquifers and onshore near surface ecosystems. Research has included observations at natural CO2 sites, laboratory and field experiments and modelling. Studies to date suggest that the impacts from many lower level fault- or well-related leakage scenarios are likely to be limited spatially and temporarily and recovery may be rapid. The effects are often ameliorated by mixing and dispersion of the leakage and by buffering and other reactions; potentially harmful elements have rarely breached drinking water guidelines. Larger releases, with potentially higher impact, would be possible from open wells or major pipeline leaks but these are of lower probability and should be easier and quicker to detect and remediate.

Phytogeographic characterization of Gran Canaria Island (Canary Islands-Spain)

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.

Paisajes para el Medioambiente. Estudio de caso.

Una de las cuencas hidrográficas más importante de la Península es la del río Tajo, por su extensión y por su caudal. Se trata de una fosa tectónica calificable de modélica. Dos moles montañosas, el Sistema central y los Montes de Toledo en sentido amplio, la flanquean al Norte y al Sur. La dovela hundida, formada por idénticos materiales que las Sierras, granitos y gneis, alcanza una gran profundidad. Al Este el Sistema Ibérico castellano, principalmente calizo y mesozoico, cierra Castilla y la cuenca, viniendo a dar vida con el agua de sus nieves a un Tajo niño’. El inicio de su Historia Geológica podemos situarlo en el Paleozoico, tiempo geológico durante el cual los territorios donde hoy se sitúa la Meseta estaban formando grandes cordilleras producto de la Orogenia Herciniana. La última etapa de la formación de los relieves actuales de la cuenca la encontramos en la reactivación de los antiguos macizos arrasados. Se inicia con los materiales de la raña y sus equivalentes en el centro de la Cuenca o Fosa del Tajo, y se caracteriza por una progresiva individualización de los procesos, pasándose de las grandes superficies generalizadas en macizos y cuencas, Sierras y Fosa del Tajo, a las pequeñas llanuras en franja u orla, que quedan localizadas en cada cuenca fluvial a medida que éstas se van consolidando por jerarquización, y partir de un río generatriz o emisario principal, el Tajo. La tectónica, procesos posteriores de captura, reajustes climáticos..., no permiten aún determinar cuál fue el orden de jerarquía en los ríos que hoy conocemos; no obstante, puede aventurarse que Jarama-Henares, Perales-Alberche y Guadarrama serían los primeros y Manzanares, Guadalix, Tajuña, los siguientes, y así sucesivamente. La síntesis de la realidad geológica, litológica y climática va a coadyuvar, frenando o favoreciendo, el desarrollo y la diferenciación entre los paisajes vegetales de las zonas montañosas y los de las depresiones terciarias y penillanuras paleozoicas, en un territorio marcado por el predominio del clima mediterráneo continentalizado, con matices de montaña y áreas de influencia atlántica.

Analysis about the society of 'Pa Negre' (Agustí Villaronga, 2010)

This article has developed with the intention of analyzing how the stereotypes, prejudices and lies can influence the education of the children. Formation, that usually comes from family and teachers, who sometimes move for extremist ideologies. There exist multiple fictions in which we observe these social archetypes, but it is the case of the movie Pa negre (Agustí Villaronga, 2010), where the principal personage evolves psychologically, because of that its eyes observe and the ideas that the people transmit him on its family, in the rural environments, where the tradition of the rumors coexists.

Sign language in Spanish television. Study on reception

The present article analyses the preferences of the deaf who use sign language and are users of the TV interpretation service to sign language, as well as the characteristics with which TV channels provide that service in television in Spain. The objective is to establish whether the way in which the aforementioned accessibility service is provided matches the preferences of users or differ from them. The analysis presents the opinion on this service of the deaf that use the Spanish sign language as their first language for communication. A study has also been conducted on the programmes broadcast with sign language during week 10-16/03/2014. The main data collected reveal that the deaf are dissatisfied with broadcasting times. They ask for news programmes with sign language, they would rather have the interpretation carried out by deaf people who use sign language and they prefer that the interpreter is the main image on screen. Concerning the analysis of the programmes broadcast, the study shows that the majority of programmes with sign language are broadcast at night, they are entertainment programmes, the interpretation is carried out by hearing people who use sign language and that their image is displayed in a corner of the screen.

Social Work and theatre: considering intersections

Theatre is a cultural and artistic form that involves a process of communication between creators and is received in a space and time located in the public sphere, which has meant that, over the centuries, it has acted as a space for expression, exchange and debate regarding all manner of ideas, causes and struggles. Implicit within this process are processes of expression, creation and reception, by way of which people demonstrate, analyse and question ways of seeing and understanding life, and ways of being and existing in the world. This gives rise to educational, cultural, social and political potential, which has been endorsed in numerous studies and investigations. In this work, in which theoretical orientation is established through a review of the relevant literature, we consider different intersections that occur between theatre and social work in order to also show that dramatic and theatrical expression offers substantive methodologies for achieving some objectives of social work, particularly in areas such as critical literacy, reflexivity and recognition, awareness raising, social participation, personal and/or community development, ownership of cultural capital and access to personal and social wellbeing.
