- Abstract
El fin de este trabajo es concienciar al alumnado acerca del cambio climático a través del uso de las canciones en las clases de francés. A la hora de trabajar este tema, los profesores suelen aportar documentos como gráficos, estadísticas y textos con una infinidad de cifras y porcentajes. Por lo que puede ser un contenido complejo, complicado o tedioso para el alumnado, y más aún para el primer ciclo de secundaria. Por este motivo, llevaremos a cabo un trabajo de innovación con una propuesta didáctica centrada en la sensibilización al cambio climático a través de la canción, un recurso que puede ser motivador a la vez que enriquecedor y ameno para los alumnos. Esta situación de aprendizaje se realizará en el IES Benito Pérez Armas e irá orientada a 1º ESO. L'objectif de ce travail est de sensibiliser les élèves au changement climatique par l'utilisation de chansons dans les cours de français. Lorsqu'ils travaillent sur ce sujet, les enseignants fournissent souvent des documents tels que des graphiques, des statistiques et des textes comportant un nombre infini de chiffres et de pourcentages. Il peut donc s'agir d'un contenu complexe, compliqué ou fastidieux pour les élèves, et encore plus pour le premier cycle de l'enseignement secondaire. Pour cette raison, nous réaliserons un travail d'innovation avec une proposition didactique axée sur la sensibilisation au changement climatique à travers la chanson, une ressource qui peut être motivante ainsi qu'enrichissante et agréable pour les élèves. Cette situation d'apprentissage sera réalisée dans l'IES Benito Pérez Armas pour les élèves de la 1 ère ESO

Uno de los grandes problemas de los centros educativos en la actualidad es el acoso escolar, el cual se manifiesta con: bajo rendimiento del alumnado, agresiones entre iguales, absentismo, baja autoestima, depresión o suicidios (en casos más excepcionales). Por ello, se ha indagado diversas publicaciones sobre el acoso escolar, seleccionando los documentos que se centran en el objetivo principal de este proyecto que es conocer qué es el acoso escolar, las causas en la etapa de la Educación Primaria, así como las consecuencias que éste provoca, como también la relevancia que tiene la inteligencia emocional en las aulas a través de la educación emocional. No obstante, es de suma importancia orientar a los docentes mejor respecto al tema a tratar, cómo intervenir en él, cómo llegar a gestionarlo, ya que a raíz de ello proceden la mayor parte de las directrices educativas que el alumnado aprende. Finalmente, se ha de reseñar que para el presente Trabajo de Fin de Grado los recursos que se han empleado han sido extraídos de las plataformas de “Dialnet y Punto Q”, ya que estas ofrecen un amplio abanico de información del cual se ha enriquecido el presente estudio de revisión teórica. One of the major problems in schools today is bullying, which manifests itself in: low student performance, aggression among peers, absenteeism, low self-esteem, depression or suicide (in more exceptional cases). For this reason, several publications on bullying have been researched, selecting the documents that focus on the main objective of this project, which is to know what bullying is, the causes in the Primary Education stage, as well as the consequences it causes, and the relevance of emotional intelligence in the classroom through emotional education. However, it is of utmost importance to guide teachers better on the subject to be dealt with, how to intervene in it, how to manage it, since most of the educational guidelines that students learn come from it. Finally, it should be noted that for this Final Degree Project the resources used have been extracted from the "Dialnet and Punto Q" platforms, since they offer a wide range of information from which this theoretical review study has been enriched.

International audience; Bryophytes have been proposed as ideal indicators of ecosystem change, because they are important components of forest integrity, and considerable research indicates that some groups are sensitive to the changes associated with specific human disturbances. Bryo-phyte richness and abundance have been found to vary predictably along elevational gradients , but the role of human impacts on these distribution patterns remains unclear. The aim of this study is to explore the impact of human disturbance on the elevational patterns of bryophyte diversity, along an elevational gradient. Along the gradient we collected three datasets in the following sites: preserved (P), forest track roadsides (R) and disturbed by agriculture/silviculture practices (D). Two survey plots of 100 m 2 were established at every 200 m elevational step for each sites P, R, D, and in each plot bryophytes were sampled in a stratified manner. At each plot we recorded all species on available substrates and estimated their percentage cover. Our results showed that species number did not differ among studied sites, but that species diversity pattern differs among the three gradient types and species life strategy composition along the elevational gradient showed a clear response to the disturbance of mature communities. We conclude that human impact has strongly changed the elevational pattern of diversity, and that these changes vary depending on the ecological and taxonomical group considered.

Método por tareas ,Aprendizaje significativo ,Competencia comunicativa - Abstract
This degree thesis is centred on an analysis of learning situations in primary education, to prove that the model of task based learning is being implemented. The choice of this topic was made, in part, to widen our knowledge of learning situations and both the different forms of working them and applying them in practice, as it is something with which we will have to face in our daily teaching as future primary school teachers. After studying various learning situations we have chosen three from each of the two Canary Island capitals, Tenerife and Gran Canaria. They have been taken from various municipalities, without delineating a specific geographical area. Also, the analysis of the results reflect that all the learning situations researched follow the model of task based learning. En el presente trabajo de fin de grado nos centramos en el análisis de situaciones de aprendizaje de Educación Primaria, para comprobar si trabajan el modelo de enseñanza por tareas. La elección de este tema está motivada, en parte, por ampliar nuestro conocimiento sobre las situaciones de aprendizaje y las distintas formas de trabajarlas y ponerlas en práctica, ya que es algo con lo que tendremos que trabajar y llevar a cabo nosotras en nuestro día a día como futuras docentes. Tras estudiar varias situaciones de aprendizaje, hemos escogido tres de cada isla capitalina, Tenerife y Gran Canaria, repartidas a lo largo de los municipios de las mismas, sin centrarnos en una zona geográfica concreta. Asimismo, se pone de manifiesto que el análisis de los resultados refleja que todas las situaciones que hemos analizado se rigen por el modelo de enseñanza por tareas.

Trabajo presentado en el II International Conference on Island Evolution, Ecology and Conservation, celebrado en Angra do Heroísmo, Islas Azores (Portugal) del 18 al 22 de julio de 2016., The European rabbit, Oryctolagus cuniculus, is an invasive mammal in the Canary Islands and a keystone species in alteration of island ecosystems worldwide. It may dramatically affect the vegetation through different mechanisms, and therefore contribute to modifying habitat and communities, producing benefits in some species and damaging others. Thus, the rabbit might be considered as an ‘ecosystem engineer’. Through a study on the population structure of the endemics shrubs Spartocytisus supranubius and Pterocephalus lasiospermus, we explored the role of rabbits as a keystone in driving changes on dominant species of the summit vegetation of El Teide National Park (Tenerife, Canary Islands). We also analysed the spatial heterogeneity of these two dominant species, their relation with the herbivores, the plant age-classes and the growth response to variation in soil nutrient availability. For these purposes 90 plots were established at 30 localities within the high mountain area. Furthermore, we used 13 permanent plots in two types of herbivore exclusions (‘only big-herbivores’ and ‘all herbivores’). In one of the localities, 100 soil samples were collected to analyse the relationship between changes in nutrients (N, NO3, K) produced by rabbits and plant growth. The population of S. supranubius is clearly declining due to the negative effect of rabbits in its regeneration, matching with a rapid increase in the population of P. lasiospermus. This study also showed that the density of rabbits is the most influential variable affecting the population structure of S. supranubius. Furthermore, the increase in nitrates and potassium favour the growth of P. lasiospermus. The high contrast in palatability between both species and the different response to the increase in nitrates and potassium, represent the main forces in explaining the current dynamic of the vegetation in the high mountain of Tenerife. Our results highlight the urgency to control the great density of rabbits in this area.

Pterocephalus lassiospermus ,Vegetation dynamic ,Invasive herbivore ,Spartocytisus supranubius - Abstract
Trabajo presentado en Floramac celebrado en Las Palmas de Gran Canaria (España) del 24 al 27 de marzo de 2015., The European rabbit, Oryctolagus cunniculus, may dramatically affect the vegetation through different mechanisms, and therefore may contribute to modify habitat and communities, producing benefits in some species and harming others. Thus, rabbit might be considered as a landscape engineer. The European rabbit is an invasive mammal in the Canary Islands, and a keystone species in the change of the ecosystems. Some studies have shown the effects of this herbivore on some threatened species, but they do not have analysed its wide scale effects on dominant species of the Canary ecosystems. Here, we have explored the role of rabbits as ecosystem engineers in the summit vegetation of the Canary Islands, through a study on the population structure of Spartocytisus supranubius and Pterocephalus lassiospermus. We have studied the spatial heterogeneity of these two dominant species and the relationship between rabbit density and age-classes. For this purpose 90 analysis plots were established along 30 localities, within the distributional area of S. supranubius. Furthermore, we used 12 permanent plots of herbivore exclusion controlled by Teide National Park. In all of them the structure and composition of vegetation, as well as the most important abiotic variables, were analyzed. This study showed that density of rabbits is the most influential variable on the population structure of S. supranubius. It also confirmed that the population of the broom scrub is declining due to the negative effect of rabbits in its regeneration and showed that the decline of S. supranubius was positively correlated with the increase of P. lasiospermus.

Ecosystems that provide environmental opportunities but are poor in species and functional richness generally support speciation as well as invasion processes. These processes are expected not to be equally effective along elevational gradients due to specific ecological, spatial, and anthropogenic filters, thus controlling the dispersal and establishment of species. Here, we investigate speciation and invasion processes along elevational gradients. We assess the vascular plant species richness as well as the number and percentage of endemic species and non-native species systematically along three elevational gradients covering large parts of the climatic range of La Palma, Canary Islands. Species richness was negatively correlated with elevation, while the percentage of Canary endemic species showed a positive relationship. However, the percentage of Canary-Madeira endemics did not show a relationship with elevation. Non-native species richness (indicating invasion) peaked at 500 m elevation and showed a consistent decline until about 1,200 m elevation. Above that limit, no non-native species were present in the studied elevational gradients. Ecological, anthropogenic, and spatial filters control richness, diversification, and invasion with elevation. With increase in elevation, richness decreases due to species-area relationships. Ecological limitations of native ruderal species related to anthropogenic pressure are in line with the absence of non-native species from high elevations indicating directional ecological filtering. Increase in ecological isolation with elevation drives diversification and thus increased percentages of Canary endemics. The best preserved eastern transect, including mature laurel forests, is an exception. The high percentage of Canary-Madeira endemics indicates the cloud forest's environmental uniqueness-and thus ecological isolation-beyond the Macaronesian islands. [ABSTRACT FROM AUTHOR]

Ecosystems that provide environmental opportunities but are poor in species and functional richness generally support speciation as well as invasion processes. These processes are expected not to be equally effective along elevational gradients due to specific ecological, spatial, and anthropogenic filters, thus controlling the dispersal and establishment of species. Here, we investigate speciation and invasion processes along elevational gradients. We assess the vascular plant species richness as well as the number and percentage of endemic species and non‐native species systematically along three elevational gradients covering large parts of the climatic range of La Palma, Canary Islands. Species richness was negatively correlated with elevation, while the percentage of Canary endemic species showed a positive relationship. However, the percentage of Canary–Madeira endemics did not show a relationship with elevation. Non‐native species richness (indicating invasion) peaked at 500m elevation and showed a consistent decline until about 1,200m elevation. Above that limit, no non‐native species were present in the studied elevational gradients. Ecological, anthropogenic, and spatial filters control richness, diversification, and invasion with elevation. With increase in elevation, richness decreases due to species–area relationships. Ecological limitations of native ruderal species related to anthropogenic pressure are in line with the absence of non‐native species from high elevations indicating directional ecological filtering. Increase in ecological isolation with elevation drives diversification and thus increased percentages of Canary endemics. The best preserved eastern transect, including mature laurel forests, is an exception. The high percentage of Canary–Madeira endemics indicates the cloud forest's environmental uniqueness—and thus ecological isolation—beyond the Macaronesian islands.
