Modelling the factors influencing ontogenetic dietary shifts in stream-dwelling brown trout (Salmo trutta)

Biotic and abiotic variables shape ontogenetic trajectories of animals. This study modelled (i) the body length related timing of the ontogenetic switch from aquatic to surface prey and (ii) the impacts of habitat characteristics, prey availability, and fish densities on the relative contribution of surface prey to the overall diet of native brown trout (Salmo trutta). We used individual-based models of dietary data for 170 fish (length range 48–343 mm). There was a high degree of individual variation in the use of surface prey, but logistic regression suggested that the shift from aquatic to surface prey was established at a body length of 81 mm (range 36–127 mm). Results of linear mixed-effects models highlighted the importance of fish length, benthic invertebrates, brown trout density, and water current velocity to the switch to surface prey by riverine brown trout, with fish length being the most influential variable. Our study provides evidence of the importance of ontogeny (intrinsic features of individuals linked to fish length) and individual differences in feeding behaviour to understand water-column use for feeding by stream-dwelling salmonidsPlan I2C (Xunta de Galicia)S

Biometric Fuzzy Extractor Scheme for Iris Templates

In: The 2009 World Congress in Computer Science, Computer Engineering, and Applied Computing (WORLDCOMP'09), The 2009 International Conference on Security and Management (SAM'09), Vol II, Proceedings 563--569. H.R. Arabnia and K. Daimi (Eds.), Las Vegas (USA), July, 2009Biometric recognition offers a reliable and natural solution to the problem of user authentication by means of her physical and behavioral traits. An iris template protection scheme which associates and retrieves a secret value with a high level of security, is proposed. The security is guaranteed thanks to the requirements of fuzzy extractors. The implementation of the scheme is done in Java and experimental results are performed to calculate its False Acceptance Rate and its False Rejection Rate.This work has been partially supported by Ministerio de Industria, Turismo y Comercio (Spain), in collaboration with CDTI and Telefónica I+D under the project SEGUR@ (CENIT-2007 2004).Peer reviewe

Ontogenetic dietary shifts and food selection of endemic Squalius carolitertii (Actinopterygii: Cypriniformes: Cyprinidae) in River Tormes, Central Spain, in summer

Background. The northern Iberian chub Squalius carolitertii (Doadrio, 1988) is a small endemic cyprinid inhabiting the rivers of the Iberian Peninsula. The knowledge of feeding patterns is essential to understand the ecological role of fish populations, helping to the development of conservation and management plans. The aim of the present study was to analyze the ontogenetic dietary shifts and food selection of S. carolitertii, contributing to knowledge of the feeding behaviour of this fish species. Materials and methods. Diet composition of S. carolitertii was compared to benthos and drift composition in a river of Central Spain (Ávila, River Tormes) using selectivity indices of Ivlev and Savage. The age of 57 S. carolitertii collected in August 2010 was determined by scale reading and by length frequency analyses (LFA) with the Petersen method. Maximum length of benthos, drift and prey invertebrates was measured for each item to establish whether prey-size selection depends upon the size-frequency distribution of available prey. Results. Detritus were found in 33 fish (57.9% of occurrence). Nymphs of Baetis spp. were the most abundant prey (46.6%) and were identified in the 49.1% of the stomachs. Moreover, Baetis spp. was selected positively from the benthos and drift by all age classes. Abundant potential prey items such as Epeorus spp. in the benthos and Simuliidae in the drift were negatively selected. Individuals without detritus in the gut contained more animal prey items than individuals with a dominance of detritus, and the frequency of occurrence of detritus decreased with the age. Mean prey size increased with fish size (r = 0.646, P < 0.001). Conclusion. Age-related diet shifts occur at three different levels: (1) frequency of occurrence of detritus decreases with fish age; (2) prey selection varied with fish age; and (3) mean prey size increased as fish size increased. The rejection of Epeorus spp. and Simuliidae suggests that other factors, apart of prey abundance, including sitespecific prey accessibility, prey size, energetic selection criteria and prey preference of fishes play an important role in feeding behaviour of S. carolitertii. Prey-size selection is probably dependent on the size-frequency distribution of the available prey.This work has been partially supported by the project 10PXIB2111059PR of the Xunta de Galicia and the project MIGRANET of the Interreg IV B SUDOE (SouthWest Europe) Territorial Cooperation Programme (SOE2/P2/E288)S

Using cartographies to map time and space in teacher learning in and outside school

This article explores the relations between teachers' visual cartographies and oral narratives to better understand the spatial and temporal relations on teacher learning. It builds on a research project whose main questions were: 1) How and where do secondary school teachers learn to teach? 2) What are the consequences of this learning in their pedagogical relations and their students' learning processes and results? Since narrative research has been a common way of approaching the subject and have led to an emphasis on learning as a journey across contexts and over time, some of its contributions to explore teachers' learning paths are theoretically discussed, and visual methods, particularly cartographies, are also examined. Furthermore, the article presents the analysis of cartographies and video recordings of 29 secondary school teachers focusing on the interactions in different spaces and moments in time described by them. Findings suggest that learning to be a teacher may happen in interactions with objects, people and spaces beyond the boundaries of school, university and formal places of training and learning. They also show that the rhizomatic character of the cartographies may not prevent teleological thinking or the idea that any kind of learning is purposeful. Finally, this paper concludes that teachers' learning does not fit the representational frame that distinguishes between formal contents and leisure activities, classrooms and private spaces, lessons and bodies, emotions and knowledge

On Noises and Furies: A Journey Through the Violence of the European Nine Hundred

La violencia es un fenómeno repudiado hoy en día por la cultura cívica y política de los países avanzados. Pero no siempre, ni hace mucho, fue así: durante buena parte del siglo XX y en casi todos los puntos geográficos del viejo continente, la violencia protagonizó las relaciones entre estados, entre naciones, entre grupos étnicos y entre clases sociales. La violencia, esa partera de la Historia en frase apócrifa atribuida a Karl Marx, se apoderó de las pasiones humanas y definió la forma en que se debían resolver las pugnas de hegemonía entre los distinto modelos de sistema —capitalismo, comunismo—, de gobierno —democracia, dictaduras—y de convivencia —nacionalismo, pluralismo—. Es al estudio de este hilo conductor de la historia reciente al que Julián Casanova ha dedicado su último ensayoViolence is a phenomenon currently repudiated by the civic and political culture of advanced countries, but not always, nor long ago, it was like this: for much of the 20th century and in almost all the geographical points of the old continent, violence hestarred in relations between states, between nations, between ethnic groups and between social classes. Violence, that midwife of History in an apocryphal phrase attributed to Karl Marx, seized human passions and defined the way in which the struggles of hegemony between the different models of system —capitalism, communism—, of government —democracy, dictatorship—and coexistence —nationalism, pluralism—. It is to the study of this common thread of recent history that Julán Casanova has dedicated his latest essa

Entre la vieja y la nueva izquierda armada : de la Unión de Combatientes Españoles al Movimiento por la IIIª República (1959-1967)

Tras el abandono de la lucha armada contra la dictadura a comienzos de los años 50, solo algunos sectores minoritarios de la izquierda en el exilio apostaron por el mantenimiento de una oposición intransigente y radicalmente opuesta al abandono del ideal republicano y a cualquier pacto con los sectores conservadores desgajados del régimen. La influencia de las luchas anticoloniales y de la revolución cubana, unida al deseo de hacer algo efectivo por la caída de Franco, llevaron a un grupo de luchadores veteranos a fundar organizaciones efímeras, como la Unión de Combatientes Españoles, en 1959, o el Movimiento por la III República y por la Reconstitución del Ejército Republicano, en 1963, últimos intentos de sumar la experiencia guerrillera de posguerra, ya bajo la influencia de la nueva izquierda revolucionaria.After the renounce to the armed struggle against Franco's dictatorship at the beginning of the fifties, only some minority groups of the exiled left showed a radical opposition to the abandonment of the republican ideal and to any pact with those conservative forces which did not support the Franco regime any more. The influence of the anticolonial struggles and the Cuban revolution, together with the desire to contribute effectively to the fall of Franco, led some veteran anti-Francoist fighters to found ephemeral organizations, like the Union of Spanish Combatants in 1959, or the Movement for the III Republic and the Reconstruction of the Republican Army in 1963, which were the last attempts to revive the guerrilla experience of the postwar period, now under the influence of the new revolutionary left
