Between but not within species variation in the distribution of fitness effects

New mutations provide the raw material for evolution and adaptation. The distribution of fitness effects (DFE) describes the spectrum of effects of new mutations that can occur along a genome, and is therefore of vital interest in evolutionary biology. Recent work has uncovered striking similarities in the DFE between closely related species, prompting us to ask whether there is variation in the DFE among populations of the same species, or among species with different degrees of divergence, i.e., whether there is variation in the DFE at different levels of evolution. Using exome capture data from six tree species sampled across Europe we characterised the DFE for multiple species, and for each species, multiple populations, and investigated the factors potentially influencing the DFE, such as demography, population divergence and genetic background. We find statistical support for there being variation in the DFE at the species level, even among relatively closely related species. However, we find very little difference at the population level, suggesting that differences in the DFE are primarily driven by deep features of species biology, and that evolutionarily recent events, such as demographic changes and local adaptation, have little impact

The GenTree Platform: growth traits and tree-level environmental data in 12 European forest tree species

Background: Progress in the field of evolutionary forest ecology has been hampered by the huge challenge of phenotyping trees across their ranges in their natural environments, and the limitation in high-resolution environmental information. Findings: The GenTree Platform contains phenotypic and environmental data from 4,959 trees from 12 ecologically and economically important European forest tree species: Abies alba Mill. (silver fir), Betula pendula Roth. (silver birch), Fagus sylvatica L. (European beech), Picea abies (L.) H. Karst (Norway spruce), Pinus cembra L. (Swiss stone pine), Pinus halepensis Mill. (Aleppo pine), Pinus nigra Arnold (European black pine), Pinus pinaster Aiton (maritime pine), Pinus sylvestris L. (Scots pine), Populus nigra L. (European black poplar), Taxus baccata L. (English yew), and Quercus petraea (Matt.) Liebl. (sessile oak). Phenotypic (height, diameter at breast height, crown size, bark thickness, biomass, straightness, forking, branch angle, fructification), regeneration, environmental in situ measurements (soil depth, vegetation cover, competition indices), and environmental modeling data extracted by using bilinear interpolation accounting for surrounding conditions of each tree (precipitation, temperature, insolation, drought indices) were obtained from trees in 194 sites covering the species’ geographic ranges and reflecting local environmental gradients. Conclusion: The GenTree Platform is a new resource for investigating ecological and evolutionary processes in forest trees. The coherent phenotyping and environmental characterization across 12 species in their European ranges allow for a wide range of analyses from forest ecologists, conservationists, and macro-ecologists. Also, the data here presented can be linked to the GenTree Dendroecological collection, the GenTree Leaf Trait collection, and the GenTree Genomic collection presented elsewhere, which together build the largest evolutionary forest ecology data collection available

Impact on Postoperative Pain and Recovery of a Regional Analgesia Strategy Based on the Surgical Approach for Lung Resection: A Prospective Observational Study

Various regional anesthesia (RA) techniques were shown to reduce pain after lung surgery, but controversies remain regarding the best technique to use to improve recovery. In this observational prospective study, the aim was to assess the efficacy of an RA strategy depending on the surgical approach. Patients who underwent lung surgery were included if an RA was planned following our unit procedure (erector spinae plane block (ESP) for video-assisted thoracic surgery (VATS) and thoracic epidural analgesia (TEA) or intrathecal analgesia (IA) for thoracotomy). Patients were compared according to the RA used. In total, 116 patients were included, 70 (60%), 32 (28%), 14 (12%) in the ESP, TEA and IA groups, respectively. Between Day 1 and Day 3, median NRS values were ≤4 at rest, and <50% patients experienced moderate-to-severe pain in each group. There were no significant differences in opioid consumption and in pain at rest or during chest physiotherapy on Days 1 and 2 between groups. However, patients who received an IA had lower NRS than other groups on Day 0 and 3 and a shorter length of hospital stay in comparison with those who received a TEA. Thus, in our institution, a strategy combining ESP for VATS and TEA, or IA for thoracotomy, allowed for effective analgesia after a lung resection. Interestingly, IA appeared to be more effective than TEA in reducing the length of hospital stay and pain on Day 0 and 3

National security to guarantee the business entrepreneurship as a form of participation in the productive development of the country under the post-conflict

La presente investigación está orientada a evidenciar que en la actualidad el emprendimiento representa un elemento fundamental para el desarrollo del país toda vez que coadyuvan a renovar el tejido productivo de la sociedad y ofrecer nuevas oportunidades de desarrollo socio-económico que potencien el desarrollo de empresas que propendan por alcanzar niveles de productividad acorde a las necesidades apremiantes del país. En este ensayo, se evidenciará el primera medida, una reflexión y análisis del concepto del Emprendimiento desde lo conceptual y epistemológico que permitirá ir avanzando a la definición del emprendimiento empresarial, teniendo en cuenta que el modelo económico y la situación colombiana, presenta la potestad de dinamizar la economía a las empresas y personas; que con los procesos de integración económicas obliga para lo local y también con una visión global. El modelo económico actual, es catalogado como neoliberal, impregnado de máximas como: competitividad, productividad, rentabilidad; significando para algunas empresas y personas: absorción de mercados, alianzas, fusiones; y, para muchos, fracaso, fragmentación, exclusión y pobreza, entre otros flagelos. Lo cierto es que las tendencias son la integración y globalización de las economías y los mercados. Ante esa realidad, se describe la situación del caso colombiano, como sigue: el mercado, marca la diferencia entre países desarrollados, y los llamados “subdesarrollados” o en palabras de (Drucker’s, 2006) “mal administrados”, por muchas razones, sobresaliendo sus condicionamientos históricos, acentuado por procesos de violencia, migración, asilo interno o desplazamiento ante la colonización que según las épocas, se ha disfrazado con diferentes palabras y actores.The present investigation is orientated to demonstrate that at present the entrepreneurship represents a fundamental element for the development of the country although they contribute to renewing the productive fabric of the company and offering new opportunities of socio-economic development that promote the development of companies that they tend for reaching levels of identical productivity to the urgent needs of the country. In this test, there will be demonstrated the first measure, a reflection and analysis of the concept of the entrepreneurship from the conceptual thing and epistemology that will allow to be advancing to the definition of the managerial entrepreneurship, bearing in mind that the economic model and the Colombian situation, presents the legal authority to stir the economy into action to the companies and persons; that with the processes of integration economic forces for the local thing and also with a global vision. The economic current model, is catalogued as neoliberal impregnated with maxims as: competitiveness, productivity, profitability; meaning for some companies and persons: absorption of markets, alliances, mergers; and, for many, I fail, fragmentation, exclusion and poverty, between other scourges. The certain thing is that the trends are the integration and globalization of the economies and the markets. Before this reality, there is described the situation of the Colombian case, as it continues: the market, it marks the difference between developed countries, and the so called "underdeveloped ones" or in words " badly administered" (Drucker’s, 2006), for many reasons, standing out his historical conditionings, accentuated by processes of violence, migration, internal asylum or displacement before the settling that according to the epochs, has disguised itself with different words and actors

The GenTree Leaf Collection: Inter‐ and intraspecific leaf variation in seven forest tree species in Europe

Trait variation within species can reveal plastic and/or genetic responses to environmental gradients, and may indicate where local adaptation has occurred. Here, we present a dataset of rangewide variation in leaf traits from seven of the most ecologically and economically important tree species in Europe. Sample collection and trait assessment are embedded in the GenTree project (EU-Horizon 2020), which aims at characterizing the genetic and phenotypic variability of forest tree species to optimize the management and sustainable use of forest genetic resources. Our dataset captures substantial intra- and interspecific leaf phenotypic variability, and provides valuable information for studying the relationship between ecosystem functioning and trait variability of individuals, and the response and resilience of species to environmental changes.Optimising the management and sustainable use of forest genetic resources in Europ

Sample collection and trait assessment are embedded in the GenTree project (EU‐Horizon 2020), which aims at characterizing the genetic and phenotypic variability of forest tree species to optimize the management and sustainable use of forest genetic resources. Our dataset captures substantial intra‐ and interspecific leaf phenotypic variability, and provides valuable information for studying the relationship between ecosystem functioning and trait variability of individuals, and the response and resilience of species to environmental changes. Main types of variable contained: We chose morphological and chemical characters linked to trade‐offs between acquisition and conservation of resources and water use, namely specific leaf area, leaf size, carbon and nitrogen content and their ratio, and the isotopic signature of stable isotope ¹³C and ¹⁵N in leaves. Spatial location and grain: We surveyed between 18 and 22 populations per species, 141 in total, across Europe. Time period: Leaf sampling took place between 2016 and 2017. Major taxa and level of measurement: We sampled at least 25 individuals in each population, 3,569 trees in total, and measured traits in 35,755 leaves from seven European tree species, i.e. the conifers Picea abies, Pinus pinaster and Pinus sylvestris, and the broadleaves Betula pendula, Fagus sylvatica, Populus nigra and Quercus petraea.
