Se citan 13 especies de Festuca L. en las comarcas de la Selva, la Garrotxa, el Alt Empordà, el Ripollès y el Pla de l’Estany (Gerona, España). Festuca occitanica (Litard.) Auquier & Kerguélen y Festuca ochroleuca Timb.-Lagr. subsp. heteroidea (Verguin) Markgr.-Dannen. suponen novedades para la flora de la Península Ibérica. Se discuten los problemas de identificación de algunos taxónes basados en la variabilidad de sus caracteres morfológicos y anatómicos13 species of the genus Festuca from la Selva, la Garrotxa, l’Alt Empordà, el Ripollès and Pla de l’Estany (Girona, Spain) are recorded. Festuca occitanica (Litard.) Auquier & Kerguélen and Festuca ochroleuca Timb.-Lagr. subsp. heteroidea (Verguin) Markgr.-Dannen. are two new records for the Iberian flora. The difficulties for the identification of the some taxa, due to the variability of their morphologic and anatomic characters, were discussed

Las gramíneas en el ambiente Pirenaico-Cantábrico

Las actuales formaciones, con los numerosos endemismos que la montaña "guarda", nos habla de las adaptaciones a la historia geológica, a los cambios climáticos, a la actividad de los herbívoros que la habitan y, más recientemente, a los usos que de la alta montaña el hombre ha realizado. La comprensión de estos hechos, nos permitirá la futura programación en aras de la conservación del espacio pirenaico.[EN] Now the vast panorama offered by grasses in spanish mountains is magnificent ; these plants show many adaptations and sophistieate strategies to persist under heavy geophysical and animal depredation ; as the local climates are now very diversified, they were surely selective in quaternary times. The scientific knowledge of endemic plants (with many adaptative strains) will be useful to imagine plant evolution and also to improve mountain's management. The historícal man action (fires and heavy grazing) favorised sorne strains of the Festuca paniculata complex coming from their rclict areas.Peer reviewe

Genetic relationships within and among Iberian fescues (Festuca L.) based on PCR-amplified markers

The genus Festuca comprises approximately 450 species and is widely distributed around the world. The Iberian Penninsula, with more than 100 taxa colonizing very diverse habitats, is one of its main centers of diversification. This study was conducted to assess molecular genetic variation and genetic relatedness among 91 populations of 31 taxa of Iberian fescues, based on several molecular markers (random amplified polymorphic DNA, amplified fragment length polymorphisms, and trnL sequences). The analyses showed the paraphyletic origin of the broad-leaved (subgenus Festuca, sections Scariosae and Subbulbosae, and subgenus Schedonorus) and the fine-leaved fescues (subgenus Festuca, sections Aulaxyper, Eskia, and Festuca). Schedonorus showed a weak relationship with Lolium rigidum and appeared to be the most recent of the broad-leaved clade. Section Eskia was the most ancient and Festuca the most recent of the fine-leaved clade. Festuca and Aulaxyper were the most related sections, in concordance with their taxonomic affinities. All taxa grouped into their sections, except F. ampla and F. capillifolia (section Festuca), which appeared to be more closely related to Aulaxyper and to a new independent section, respectively. Most populations clustered at the species level, but some subspecies and varieties mixed their populations. This study demonstrated the value in combining different molecular markers to uncover hidden genetic relationships between populations of Festuca

Implementation of a mindfulness-based crisis intervention for frontline healthcare workers during the COVID-19 outbreak in a public general hospital in Madrid, Spain

Introduction: The COVID-19 outbreak is having an impact on the well-being of healthcare workers. Mindfulness-based interventions have shown effectiveness in reducing stress and fostering resilience and recovery in healthcare workers. There are no studies examining the feasibility of brief mindfulness-based interventions during the COVID-19 outbreak. Materials and Methods: This is an exploratory study with a post intervention assessment. We describe an on-site brief mindfulness intervention and evaluate its helpfulness, safety, and feasibility. Results: One thousand out of 7,000 (14%) healthcare workers from La Paz University Hospital in Madrid (Spain) participated in at least one session. One hundred and fifty out of 1,000 (15%) participants filled out a self-report questionnaire evaluating the helpfulness of the intervention for on-site stress reduction. Ninety two subjects (61%) participated in more than one session. Most of the participants were women (80%) with a mean age of 38.6 years. Almost half of the sample were nurses (46%). Sessions were perceived as being helpful with a mean rating of 8.4 on a scale from 0 to 10. Only 3 people (2%) reported a minor adverse effect (increased anxiety or dizziness). Discussion: Our data supports the utility, safety and feasibility of an on-site, brief mindfulness-based intervention designed to reduce stress for frontline health workers during a crisis. There is a need to continue testing this type of interventions, and to integrate emotion regulation strategies as an essential part of health workers' general training. Clinical Trial Registration number: NCT04555005
