The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for "inappropriate" names. It is evident that such proposals come from very deep feelings, but we show how they can irreparably damage the foundation of biological communication and, in turn, the sciences that depend on it. There are four essential consequences of objective codes of nomenclature: universality, stability, neutrality, and transculturality. These codes provide fair and impartial guides to the principles governing biological nomenclature and allow unambiguous universal communication in biology. Accordingly, no subjective proposals should be allowed to undermine them.

Syngameons represent networks of otherwise distinct species interconnected by limited gene exchange. Although most studies have focused on how species maintain their cohesiveness despite gene flow in these networks, there are additional relevant questions regarding the evolutionary dynamics of syngameons and their drivers, as well as the success of their members and the whole network. Using a ddRADseq approach, we analyzed the genetic structure, genomic clines and demographic history of a coastal hybrid zone involving two species of the Armeria (Plumbaginaceae) syngameon in Southern Spain. We inferred that one peripheral population of the sand dune-adapted A. pungens experienced genetic drift after a founder event and was subsequently introgressed by a local more abundant pinewood congener, A. macrophylla. This led to plastid capture resulting in extensive plastid DNA haplotype sharing between the two species across the whole hybrid zone. Genomic cline analysis identified bidirectional introgression, but more outliers with an excess ancestry of A. pungens than of A. macrophylla, which suggests A. pungens alleles are being selected for. This is consistent with the findings that A. pungens phenotype is selected for in open habitats. This scenario implies that bidirectional introgression is, on the one side, driven by demographic forces towards the immigrant range-edge bottlenecked population of A. pungens, which reduces its risk of stochastic extinction and increases its evolutionary potential as a novel hybrid lineage. On the other side, introgression towards A. macrophylla is driven by selection of alleles with A. pungens ancestry, enabling individuals to grow in open highly-irradiated habitats.

Introducción: La comunidad universitaria de la Universidad Complutense de Madrid (UCM) es diversa, existiendo una gran variedad de formas de alimentarse influenciadas por distintos contextos (culturales, religiosos, sanitarios, etc.), dando lugar en algunas ocasiones, a la aparición de restricciones alimentarias por estos motivos (de origen religioso, ético/moral, por salud…). Estas restricciones pueden afectar al bienestar emocional, la salud o incluso derivar en situaciones de discriminación para las personas que las siguen, sobre todo en lugares en los que no existan recursos suficientes para llevarlas a cabo o donde estas sean menos conocidas. El objetivo principal del proyecto fue estudiar la diversidad cultural existente dentro de la UCM, identificar las principales restricciones alimentarias que existen entre los integrantes de la comunidad universitaria (estudiantes y personal docente e investigador) así como divulgar y concienciar sobre esta materia. Metodología: Se diseñó una encuesta con 44 preguntas dirigida a la comunidad universitaria con el objetivo de realizar un estudio observacional transversal. Se creó una escala tipo Likert para medir la discriminación autopercibida en relación con las restricciones alimentarias, utilizando el análisis factorial de componentes principales y la prueba de la alfa de Cronbach con el programa estadístico SPSS v22.0 para medir la validez y fiabilidad de la escala diseñada en una muestra de participantes inicial (n = 324). Más tarde, con la muestra final del proyecto (n = 1691) se analizaron las preguntas de la encuesta con los programas JASP v0.18.1 y SPSS v22.0, obteniendo las prevalencias de las restricciones alimentarias acompañadas de los intervalos de confianza al 95%. Se calcularon las medias ± desviación estándar y las medianas junto los rangos intercuartílicos de las variables cuantitativas. Se compararon las puntuaciones de la escala de discriminación autopercibida entre las diferentes restricciones alimentar

Invasive alien species have widespread impacts on native biodiversity and ecosystem services. Since the number of introductions worldwide is continuously rising, it is essential to prevent the entry, establishment and spread of new alien species through a systematic examination of future potential threats. Applying a three-step horizon scanning consensus method, we evaluated non-established alien species that could potentially arrive, establish and cause major ecological impact in Spain within the next 10 years. Overall, we identified 47 species with a very high risk (e.g. Oreochromis niloticus, Popillia japonica, Hemidactylus frenatus, Crassula helmsii or Halophila stipulacea), 61 with high risk, 93 with moderate risk, and 732 species with low risk. Many of the species categorized as very high or high risk to Spanish biodiversity are either already present in Europe and neighbouring countries or have a long invasive history elsewhere. This study provides an updated list of potential invasive alien species useful for prioritizing efforts and resources against their introduction. Compared to previous horizon scanning exercises in Spain, the current study screens potential invaders from a wider range of terrestrial, freshwater, and marine organisms, and can serve as a basis for more comprehensive risk analyses to improve management and increase the efficiency of the early warning and rapid response framework for invasive alien species. We also stress the usefulness of measuring agreement and consistency as two different properties of the reliability of expert scores, in order to more easily elaborate consensus ranked lists of potential invasive alien species.

There is a growing interest in increasing the flexibility and the mobility of industrial infrastructures to support novel industrial applications. To support this change, industrial networks must provide real-time guarantees while integrating a great variety of traffic over a cohesive network infrastructure. Specifically, there is special interest in the integration of wired and wireless communications in the industrial domain. We present a solution that integrates a Time-Sensitive Networking Ethernet network with a low-power 6TiSCH IoT network and discuss the implementation alternatives and their implications on delay and resource consumption. The main goal is to experimentally identify the research challenges and necessary enhancements for interoperability between constrained battery-driven wireless communication with the time sensitive wired networks.

El Real Jardín Botánico (RJB) ocupa un lugar muy prominente en la ciencia botánica y de los hongos, y es un centro de excelencia del Consejo Superior de Investigaciones Científicas (CSIC) que lleva a cabo una investigación multidisciplinar en 5 de los 6 reinos de organismos eucariotas del árbol de la vida. Las investigaciones del RJB se enfocan en comprender la sistemática y evolución de la diversidad de organismos de estos 5 reinos, desde sus genes, las especies y los ecosistemas de los que forman parte. El RJB desarrolla líneas de investigación frontera enfocadas desde la sistemática y florística de plantas vasculares, la biodiversidad, biogeografía y sistemática molecular de hongos, hasta la biología evolutiva de plantas y sus patrones, procesos y mecanismos, la colonización y evolución en islas oceánicas, y la biodiversidad escondida, ahondando en el estudio de su ecología, evolución y conservación. El RJB está situado en un lugar privilegiado de Madrid, junto a la Glorieta de Atocha, y ha de sobrevivir a las nuevas como son el cambio global, incluido el cambio climático y la contaminación atmosférica.

The breeding system of Anacyclus linearilobus, an annual and endemic species restricted to dune ecosystems of the Algerian coast were assessed through the effect of self-fertilization and intra- and inter-population artificial crosses on the probability of producing viable seeds in 20 individuals from two populations in a common garden. The breeding system was determined for each individual by the self-incompatibility index (ISI). These results were compared with those published for other species of the genus, A. clavatus, A. homogamos and A. valentinus. Results of experimental crosses showed that there was high variation in the female reproductive success between individuals of A. linearilobus, like that found in its sister species, A. valentinus. Unlike the other species in the genus that are self-incompatible, A. linearilobus showed a mixed mating system, with a majority of self-incompatible individuals, others partially self-incompatible and some self-compatible. We argue that this strategy may be related to reproductive assurance in this endemic, annual species whose effective population size has been reduced probably due to individual mating incompatibilities., Se evaluó el sistema de cruzamiento de Anacyclus linearilo-bus, una especie anual y endémica, de reducida distribución en ecosiste-mas dunares de la costa argelina, mediante la probabilidad de producir semillas en 20 individuos de dos poblaciones, cultivadas en jardín. El sistema de reproducción se determinó para cada individuo por el índice de autoincompatibilidad (ISI). Estos resultados se compararon con los publicados para otras especies del género, A. clavatus, A. homogamosy A. valentinus. Los resultados de los cruces experimentales mostraron que hubo una gran variación en el éxito reproductivo femenino entre individuos de A. linearilobus, como la encontrada en su especie herma-na, A. valentinus. A diferencia de las otras especies del género que son autoincompatibles, A. linearilobus mostró un sistema de cruzamiento mixto, con una mayoría de individuos autoincompatibles, otros parcial-mente autoincompatibles y algunos autocompatibles. Argumentamos que esta estrategia puede estar relacionada con el aseguramiento repro-ductivo en esta especie anual endémica cuyo tamaño efectivo de po-blación se ha reducido probablemente debido a incompatibilidad entre individuos emparentados.
