    El proyecto se propone crear y difundir herramientas para facilitar la implantación de metodologías grupales y participativas en el aula. Se define tres momentos del desarrollo del curso (comienzos, desarrollo y final). Con la participación de 50 docentes de distintas disciplinas se recopilan perfeccionan y exponen técnicas que faciliten la participación, motivación y compromiso de los estudiantes

    Coexistence of Two Invasive Species, Procambarus clarkii and Aphanomyces astaci, in Brackish Waters of a Mediterranean Coastal Lagoon

    Procambarus clarkii is a worldwide freshwater invasive crustacean from North America and was first introduced into Europe the 1970s. Along with P. clarkii, another invasive alien species was also spreading: Aphanomyces astaci. This pathogen is listed among the 100 World’s worst invasive species and involved in the European native crayfish decline. Although both species live in freshwater ecosystems, P. clarkii can withstand brackish waters and inhabit estuarine habitats. However, the presence of A. astaci associated to North American crayfishes has never been described in brackish waters. In this study, we have investigated the presence of A. astaci in a P. clarkii population of a Mediterranean coastal lagoon in the Albufera Natural Park, Valencia, Spain introduced in 1976. Our study confirmed the presence of this pathogen, and suggests that A. astaci has been spreading for more than four decades in the mentioned estuarine environment. Mitochondrial ribosomal rnnS and rnnL indicated that the isolated pathogen belongs to d1-haplotype (i.e., D-haplogroup) typically hosted by P. clarkii. The presence of this pathogen in a brackish environment may suggest a better adaptation than other A. astaci strains to adverse conditions, such as high salinity levels. This is a matter of concern for the conservation of European native freshwater crayfish and highlights once more the risk of introducing invasive alien crustaceans.e acknowledge support of the publication fee to the Frontiers Fee Support program and the CSIC Open Access Publication Support Initiative through its Unit of Information Resources for Research (URICI).

    Educational Climate in Medicine: Opportunities for Improvement

    El entorno donde se desarrolla la formación, las relaciones alumno-profesor, los aspectos físicos (facultad/hospital) como hábitat, etc. es percibido por los alumnos influyendo en su comportamiento y lo determinan de forma importante, condicionando la consecución de los objetivos, la satisfacción y el éxito. Si el entorno educativo no es adecuado, se dificulta la adquisición de conocimientos y/o de valores de los futuros profesionales y las facultades de medicina deben reflexionar seriamente para aplicar los cambios necesarios para mejorar la enseñanza. En la enseñanza, tan importante es establecer un contexto o clima para el aprendizaje adecuado, como impartir conocimientos o compartir experiencias. Se propone identificar las deficiencias, es decir, los aspectos críticos del clima de aprendizaje como base para las medidas de optimización, así como las fortalezas de un currículo o plan de estudios. Observar las expectativas de los estudiantes con las actuales experiencias, para identificar puntos que requieran mejoras y comparar el ambiente de aprendizaje en diferentes lugares y etapas, entre los estudiantes de los diferentes cursos del Grado en Medicina de la Universidad Complutense de Madrid.The environment where training takes place, the student-professor relationships, the physical aspects (faculty/hospital) as a habitat, etc. is perceived by the students and influences their behavior and determines it in an important way, conditioning the achievement of objectives, satisfaction and success. If the educational environment is not adequate, the acquisition of knowledge and/or values of future professionals is hindered and medical schools should seriously reflect in order to implement the necessary changes to improve teaching. In teaching, it is as important to establish a context or climate for adequate learning as it is to impart knowledge or share experiences. It is proposed to identify deficiencies, i.e., critical aspects of the learning climate as a basis for optimization measures, as well as the strengths of a curriculum or syllabus. To observe students' expectations with current experiences, to identify points requiring improvement and to compare the learning environment in different places and stages, among students of different courses of the Degree in Medicine at the Complutense University of Madrid.Sección Deptal. de Bioquímica y Biología Molecular (Medicina)Fac. de MedicinaFALSEsubmitte
