    Colonization Pattern of Abandoned Croplands by Quercus pyrenaica in a Mediterranean Mountain Region

    Get PDF
    Land abandonment is a major global change driver in the Mediterranean region, where anthropic activity has played an important role in shaping landscape configuration. Understanding the woodland expansion towards abandoned croplands is critical to develop effective management strategies. In this study, we analyze the colonization pattern of abandoned croplands by Quercus pyrenaica in the Sierra Nevada mountain range (southern Spain). We aimed to assess differences among populations within the rear edge of the Q. pyrenaica distribution. For this purpose, we characterized (i) the colonization pattern of Q. pyrenaica, (ii) the structure of the seed source (surrounding forests), and (iii) the abundance of the main seed disperser (Eurasian jay, Garrulus glandarius). The study was conducted in five abandoned croplands located in two representative populations of Q. pyrenaica located on contrasting slopes. Vegetation plots within three habitat types (mature forest, edge-forest and abandoned cropland) were established to compute the abundance of oak juveniles. The abundance of European jay was determined using data of bird censuses (covering 7 years). Our results indicate that a natural recolonization of abandoned croplands by Q. pyrenaica is occurring in the rear edge of the distribution of this oak species. Oak juvenile abundance varied between study sites. Neither the surrounding-forest structure nor the abundance of jays varied significantly between study sites. The differences in the recolonization patterns seem to be related to differences in the previous- and post-abandonment management.LIFE-ADAPTAMED (LIFE14CCA/ES/000612) projectMIGRAME Project (Excellence Research Group Programme of the Andalusian Government (RNM 6734)eLTER H2020 projec

    Quantitative and qualitative research: studies on cultural motivations and customs related to Latin American-influenced flamenco songs

    Esta aportación se presenta como un nexo que vincula y da continuidad a las actividades de investigación relacionadas con diversos aspectos del comportamiento de consumo cultural universitario que se vienen realizando desde el Observatorio Cultural del Proyecto Atalaya. En concreto, los estudios revisados son los que se agrupan bajo la denominación genérica Proyecto USOS; así como, el que lleva por título Estudio cualitativo de motivaciones culturales de los estudiantes universitarios; que se encuentra actualmente en período de ejecución. Dada la complejidad inherente al comportamiento de consumo cultural y a las distintas facetas que pueden estar implicadas en el mismo, argumentamos en pro de la conveniencia de partir de metodologías cuantitativas y cualitativas que permitan enriquecer el conocimiento que se tiene del objeto de estudio

    Efecto de la música agradable y no elegida en la Memoria de Trabajo y rendimiento académico bajo una tarea aritmética

    Get PDF
    En el presente documento se trata de estudiar el efecto que ejerce la música definida como agradable, aquella que es habitual y escuchen entre los intereses de los alumnos, y no elegida, en la memoria de trabajo y el rendimiento académico en una tarea o prueba de aritmética. En este sentido, se incluirá el análisis del juicio moral, relacionando la influencia de las funciones propias de la corteza prefrontal en actividades automáticas y de planificación como puede ser una tarea numérica, valorando elementos de desarrollo moral. Para realizar este estudio, se seleccionaron alumnos de Educación Primaria, específicamente de 5º curso. Los resultados indican que los alumnos, ante música de su elección reducen su atención y memoria de trabajo y, por tanto, su rendimiento académico.Universidad de Málaga.

    Floquet stability analysis of a two-layer oscillatory flow near a flexible wall

    Get PDF
    We investigate the linear Floquet stability of two fluid layers undergoing oscillations in the direction parallel to the flexible wall that separates them. This canonical configuration is inspired by the cerebrospinal fluid flow in the spinal canal of subjects with hydromyelia/syringomyelia. The analysis focuses on the marginal conditions for the onset of instability, and how these depend on the spatial wavelength of the perturbation, and on the values of the control parameters, which are the two channel widths, the Reynolds number and the wall stiffness. Unstable perturbations are found to oscillate synchronous with the base flow. The wavelength of the most unstable perturbation, of the order of the stroke length of the basic oscillatory motion, depends strongly on the wall stiffness, but is only weakly influenced by the channel widths and the Reynolds number. In general, around criticality, it was found that increasing the Reynolds number has a destabilizing effect, and that decreasing the canal widths stabilizes the instability. The wall stiffness on the other hand has a non-monotonic effect, exhibiting an intermediate value for which the instability is maximally amplified. The present analysis is a first step towards a better understanding of the physical mechanisms that govern many (bio)fluid mechanical problems that involve oscillatory flows near compliant walls.Coordinated project, PID2020-115961RB-C31, PID2020-115961RBC32 and PID2020-115961RA-C33, financed by MCIN/AEI/10.13039/501100011033Junta de Andalucía and European Funds, project no.

    Dataset of Phenology of Mediterranean high-mountain meadows flora (Sierra Nevada, Spain)

    Get PDF
    Sierra Nevada mountain range (southern Spain) hosts a high number of endemic plant species, being one of the most important biodiversity hotspots in the Mediterranean basin. The high-mountain meadow ecosystems (borreguiles) harbour a large number of endemic and threatened plant species. In this data paper, we describe a dataset of the flora inhabiting this threatened ecosystem in this Mediterranean mountain. The dataset includes occurrence data for flora collected in those ecosystems in two periods: 1988–1990 and 2009–2013. A total of 11002 records of occurrences belonging to 19 orders, 28 families 52 genera were collected. 73 taxa were recorded with 29 threatened taxa. We also included data of cover-abundance and phenology attributes for the records. The dataset is included in the Sierra Nevada Global-Change Observatory (OBSNEV), a long-term research project designed to compile socio-ecological information on the major ecosystem types in order to identify the impacts of global change in this area.This research work was conducted in the collaborative framework of the “Sierra Nevada Global Change Observatory” Project funded by the Environment Department of Andalusian Regional Government and the Sierra Nevada National Park.
