VERMICOMPOSTOS E CINZA DE OSSOS NO DESENVOLVIMENTO INICIAL DE RABANETE E RÚCULA

The demand for and healthy vegetables with higher quality makes it necessary to seek new cultivation techniques, or yet, obtain greater efficiency and savings for those already known. Knowing the great demand and extraction of nutrients by vegetables, the present work aimed to estimate the effect of vermicomposts and bone ash, in the production of arugula and radish. The organic residues used for the production of the vermicomposts were: cattle and poultry manure. Eisenia foetida earthworms were used to produce humus. Bone ash was obtained by burning a bovine carcass. The experimental design was completely randomized with 12 treatments formed from the combination of four different formulations, three doses and three replications. The effect of the treatments was evaluated for radish cultivar 'Crimson Gigante' and arugula cultivar 'Cultivada' in an environment with 50% shading. For the radish, the following characteristics were evaluated: fresh and dry masses of roots and shoots; length of fasciculate roots; length and diameter of tuberous roots; number of leaves and leaf area. And for the Arugula, the following ones: number of leaves; root length; leaf area; fresh and dry masses of the aerial part and roots. Humus from cattle manure allows better responses to the radish, at 200 t ha-1. For the arugula, we recommend using 200 t ha-1 of vermicomposts from bovine and poultry manure together with bone ash.La demanda de verduras saludables y de calidad hace que sea necesario buscar nuevas técnicas de cultivo y obtener una mayor eficiencia y ahorro en las ya conocidas. Conociendo la gran demanda y extracción de nutrientes por parte de los vegetales, el presente trabajo tuvo como objetivo estimar el efecto del vermicompostaje y la ceniza ósea en la producción de rúcula y rábano. Fueron utilizados residuos orgánicos de ganado y pollo para la producción de los compuestos. Las lombrices de tierra Eisenia foetida se utilizaron para producir humus. La ceniza ósea se obtuvo quemando un cadáver bovino. El diseño experimental fue completamente al azar con 12 tratamientos formados a partir de la combinación de cuatro formulaciones diferentes, tres dosis y tres repeticiones. El efecto de los tratamientos se evaluó para el rábano cultivar 'Crimson Gigante' y la rúcula cultivar 'Cultivada' en un ambiente con 50% de sombra. Para el rábano, se evaluaron las siguientes características: masas frescas y secas de raíces y brotes; longitud de las raíces fasciculadas; longitud y diámetro de raíces tuberosas; Número de hojas y área foliar. Y para la rúcula, se evaluó lo siguiente: número de hojas; longitud de la raíz; área foliar; masas frescas y secas de la parte aérea y raíces. El humus del estiércol del ganado permite mejores respuestas al rábano, a 200 t ha-1. En cuanto al cultivo de rúcula, se recomienda usar 200 t ha-1 de vermicompuestos de estiércol bovino y avícola junto con harina de huesos.A demanda por olerícolas de qualidade e saudáveis torna necessário buscar novas técnicas de cultivo, ou ainda obter maior eficiência e economia nas já conhecidas. Conhecendo a grande demanda e extração de nutrientes pelas hortaliças, o presente trabalho objetivou estimar o efeito de vermicompostos e de cinza de ossos, na produção de rúcula e de rabanete. Os resíduos orgânicos utilizados para a produção dos compostos foram: esterco bovino e de galinha. Foram utilizadas minhocas da espécie Eisenia foetida para produção do húmus. A cinza de ossos foi obtida pela queima de uma carcaça bovina. O delineamento experimental foi o inteiramente casualizado com 12 tratamentos formados da combinação de quatro diferentes formulações, três doses e três repetições. O efeito dos tratamentos foi avaliado para o rabanete cultivar ‘Crimson Gigante’ e a rúcula cultivar ‘Cultivada’ em ambiente com 50% de sombreamento. Para o rabanete, foram avaliadas as seguintes características: massas fresca e seca das raízes e parte aérea; comprimento das raízes fasciculadas; comprimento e diâmetro das raízes tuberosas; número de folhas e área foliar. E para a Rúcula foram avaliados: número de folhas; comprimento das raízes; área foliar; massas fresca e seca da parte aérea e raízes. O húmus a partir de esterco bovino permite melhores respostas para o rabanete, a 200 t ha-1. Já para a cultura da rúcula, é recomendado o uso de 200 t ha-1 de vermicompostos a partir de esterco bovino e de aves juntamente com farinha de ossos

Latin Americans show wide-spread Converso ancestry and imprint of local Native ancestry on physical appearance

Historical records and genetic analyses indicate that Latin Americans trace their ancestry mainly to the intermixing (admixture) of Native Americans, Europeans and Sub-Saharan Africans. Using novel haplotype-based methods, here we infer sub-continental ancestry in over 6,500 Latin Americans and evaluate the impact of regional ancestry variation on physical appearance. We find that Native American ancestry components in Latin Americans correspond geographically to the present-day genetic structure of Native groups, and that sources of non-Native ancestry, and admixture timings, match documented migratory flows. We also detect South/East Mediterranean ancestry across Latin America, probably stemming mostly from the clandestine colonial migration of Christian converts of non-European origin (Conversos). Furthermore, we find that ancestry related to highland (Central Andean) versus lowland (Mapuche) Natives is associated with variation in facial features, particularly nose morphology, and detect significant differences in allele frequencies between these groups at loci previously associated with nose morphology in this sample.Instituto Multidisciplinario de Biología Celula

Reconstructing Native American Population History

The peopling of the Americas has been the subject of extensive genetic, archaeological and linguistic research; however, central questions remain unresolved1–5. One contentious issue is whether the settlement occurred via a single6–8 or multiple streams of migration from Siberia9–15. The pattern of dispersals within the Americas is also poorly understood. To address these questions at higher resolution than was previously possible, we assembled data from 52 Native American and 17 Siberian groups genotyped at 364,470 single nucleotide polymorphisms. We show that Native Americans descend from at least three streams of Asian gene flow. Most descend entirely from a single ancestral population that we call “First American”. However, speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream. We show that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. A major exception is in Chibchan-speakers on both sides of the Panama Isthmus, who have ancestry from both North and South America

Global transpiration data from sap flow measurements : the SAPFLUXNET database

Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, and carbon budgets at the land-atmosphere interface. However, despite being the main land evaporative flux at the global scale, transpiration and its response to environmental drivers are currently not well constrained by observations. Here we introduce the first global compilation of whole-plant transpiration data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021). We harmonized and quality-controlled individual datasets supplied by contributors worldwide in a semi-automatic data workflow implemented in the R programming language. Datasets include sub-daily time series of sap flow and hydrometeorological drivers for one or more growing seasons, as well as metadata on the stand characteristics, plant attributes, and technical details of the measurements. SAPFLUXNET contains 202 globally distributed datasets with sap flow time series for 2714 plants, mostly trees, of 174 species. SAPFLUXNET has a broad bioclimatic coverage, with woodland/shrubland and temperate forest biomes especially well represented (80 % of the datasets). The measurements cover a wide variety of stand structural characteristics and plant sizes. The datasets encompass the period between 1995 and 2018, with 50 % of the datasets being at least 3 years long. Accompanying radiation and vapour pressure deficit data are available for most of the datasets, while on-site soil water content is available for 56 % of the datasets. Many datasets contain data for species that make up 90 % or more of the total stand basal area, allowing the estimation of stand transpiration in diverse ecological settings. SAPFLUXNET adds to existing plant trait datasets, ecosystem flux networks, and remote sensing products to help increase our understanding of plant water use, plant responses to drought, and ecohydrological processes. SAPFLUXNET version 0.1.5 is freely available from the Zenodo repository (https://doi.org/10.5281/zenodo.3971689; Poyatos et al., 2020a). The "sapfluxnetr" R package - designed to access, visualize, and process SAPFLUXNET data - is available from CRAN.Peer reviewe

EuReCa ONE—27 Nations, ONE Europe, ONE Registry A prospective one month analysis of out-of-hospital cardiac arrest outcomes in 27 countries in Europe

AbstractIntroductionThe aim of the EuReCa ONE study was to determine the incidence, process, and outcome for out of hospital cardiac arrest (OHCA) throughout Europe.MethodsThis was an international, prospective, multi-centre one-month study. Patients who suffered an OHCA during October 2014 who were attended and/or treated by an Emergency Medical Service (EMS) were eligible for inclusion in the study. Data were extracted from national, regional or local registries.ResultsData on 10,682 confirmed OHCAs from 248 regions in 27 countries, covering an estimated population of 174 million. In 7146 (66%) cases, CPR was started by a bystander or by the EMS. The incidence of CPR attempts ranged from 19.0 to 104.0 per 100,000 population per year. 1735 had ROSC on arrival at hospital (25.2%), Overall, 662/6414 (10.3%) in all cases with CPR attempted survived for at least 30 days or to hospital discharge.ConclusionThe results of EuReCa ONE highlight that OHCA is still a major public health problem accounting for a substantial number of deaths in Europe.EuReCa ONE very clearly demonstrates marked differences in the processes for data collection and reported outcomes following OHCA all over Europe. Using these data and analyses, different countries, regions, systems, and concepts can benchmark themselves and may learn from each other to further improve survival following one of our major health care events
