El género Evax Gaertn. (Compositae) en Galicia (España)

Se presenta una revisión del género Evax en Galicia. Se aporta la descripción de los táxones presentes y una clave para diferenciarlos. Se realiza un estudio biométrico de los aquenios de Evax pygmaea para diferenciar las subespecies. Se incluyen fotografías de sus aquenios y mapas de distribución en el área estudiada. Las poblaciones de E. pygmaea en Galicia son fundamentalmente costeras y se adscriben a la subsp. ramosissima mientras que E. lasiocarpa parece acantonarse en las montañas del SE de la región. Se reivindica la prioridad del nombre E. lasiocarpa Lange ex Cutanda sobre E. carpetana Lange.This is a revision of the genus Evax in Galicia. It is provided a description of the taxa in the region and a key to differentiate them. It becomes a study of biometric achenes of Evax pygmaea to differentiate subspecies. It includes photographs of their achenes and maps of their distribution in the study area. The populations of E. pygmaea in Galicia are mainly coastal and belong to the subsp. ramosissima while E. lasiocarpa seems to be located in the mountains of SE in the region. It claims the priority of the name E. lasiocarpa Lange ex Cutanda on E. carpetana Lange

Early survival and growth plasticity of 33 species planted in 38 arboreta across the European Atlantic area

To anticipate European climate scenarios for the end of the century, we explored the climate gradient within the REINFFORCE (RÉseau INFrastructure de recherche pour le suivi et l’adaptation des FORêts au Changement climatiquE) arboreta network, established in 38 sites between latitudes 37 and 57 , where 33 tree species are represented. We aim to determine which climatic variables best explain their survival and growth, and identify those species that are more tolerant of climate variation and those of which the growth and survival future climate might constrain. We used empirical models to determine the best climatic predictor variables that explain tree survival and growth. Precipitation-transfer distance was most important for the survival of broadleaved species, whereas growing-season-degree days best explained conifer-tree survival. Growth (annual height increment) was mainly explained by a derived annual dryness index (ADI) for both conifers and broadleaved trees. Species that showed the greatest variation in survival and growth in response to climatic variation included Betula pendula Roth, Pinus elliottii Engelm., and Thuja plicata Donn ex D.Don, and those that were least affected included Quercus shumardii Buckland and Pinus nigra J.F.Arnold. We also demonstrated that provenance differences were significant for Pinus pinea L., Quercus robur L., and Ceratonia siliqua L. Here, we demonstrate the usefulness of infrastructures along a climatic gradient like REINFFORCE to determine major tendencies of tree species responding to climate changesinfo:eu-repo/semantics/publishedVersio

El Género Eucalyptus (Myrtaceae) en Galicia: Claves y descripción

This review focuses on the species of genus Eucalyptus (Myrtaceae) that are forest interested, planted or naturalized in Galicia, excluding those that only flourish in parks and gardens. Besides using poor herbarium material, we carried out recollections based on data provided by the forest districts, organizations and individuals as well as field trips by different areas of Galicia. Based on the morphological characteristics, 40 taxa (37 species and 3 subspecies), including several hybrids, have been identified. We have also included two keys to help in identification, which are the number of flowers per peduncle and the type of bark. In this review, we provide an overview of the present knowledge on the identification, description and distribution of each of the taxa.Se ha realizado una revisión de las especies de interés forestal, plantadas o asilvestradas, del género Eucalyptus (Myrtaceae) en Galicia, excluyendo aquellas que sólo se desarrollan en parques y jardines. Además del escaso material de herbario, nos hemos basado en herborizaciones basadas en datos aportados por los distritos forestales, organizaciones forestales y particulares, así como recorridos por distintas zonas de Galicia. En base a los caracteres morfológicos, se han identificado 40 taxa (37 especies y 3 subespecies) incluyendo varios híbridos. Se han confeccionado 2 claves de identificación, basadas en el número de flores por pedicelo o por el tipo de corteza. Aportamos una iconografía para facilitar la identificación, así como una descripción de cada uno de los taxa identificados y algunos datos sobre su distribución
