Global data on earthworm abundance, biomass, diversity and corresponding environmental properties

Publisher Copyright: © 2021, The Author(s).Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties. Datasets were required, at a minimum, to include abundance or biomass of earthworms at a site. Where possible, site-level species lists were included, as well as the abundance and biomass of individual species and ecological groups. This global dataset contains 10,840 sites, with 184 species, from 60 countries and all continents except Antarctica. The data were obtained from 182 published articles, published between 1973 and 2017, and 17 unpublished datasets. Amalgamating data into a single global database will assist researchers in investigating and answering a wide variety of pressing questions, for example, jointly assessing aboveground and belowground biodiversity distributions and drivers of biodiversity change.Peer reviewe

Glotopolítica latinoamericana : Tendencias y perspectivas

Glotopolítica latinoamericana: tendencias y perspectivas recoge el resultado de presentaciones y deliberaciones del IV Congreso Latinoamericano de Glotopolítica, realizado en la Universidad de San Pablo (Brasil) en septiembre de 2019, que convocó a numerosos y destacados especialistas en el área. Su inscripción en una serie (los anteriores se realizaron en Chile, Colombia y Alemania) nos permite apreciar los grandes ejes de los que da cuenta el cuidadoso e inteligente armado del libro decidido por los editores, y fundamentado en la Presentación. El tramo que hemos recorrido como especialistas, en el cual los eventos internacionales son hitos significativos, ha ido mostrando la amplitud de un campo que se construye apelando a tradiciones académicas variadas, que insiste en su carácter interdisciplinario y crítico y que no deja de tener una dimensión militante que se expone en las reflexiones teóricas, las investigaciones empíricas y las prácticas institucionales

Mercados y tianguis en el siglo XXI. Repensando sus problemáticas

Los capítulos que conforman esta obra se acercan a los mercados y tianguis principalmente desde las ciencias sociales, económicas y biológicas. Sin embargo, a diferencia de estudios realizados en décadas pasadas, han encontrado nuevas problemáticas, como, por ejemplo, la relación clientelar de locatarios y tianguistas con agrupaciones mayores y partidos políticos. También se describe la disputa del mercado entre personas locales y turistas, es decir, los problemas que emergen de la museificación de estos espacios. Además, el tema de los supermercados, espacios que han ganado terreno, actualmente no deben disociarse de las lógicas comerciales de consumo.En el mundo globalizado en que vivimos, los mercados y tianguis se enfrentan a procesos de adaptación social, cultural, política y económica. Existen prácticas que continúan mientras que, a la par, aparecen nuevas formas de relacionarse con estos espacios. Por ello, los compiladores del libro, así como las y los especialistas que escriben en él, invitamos a la comunidad lectora a que utilice este libro como un referente que puede ayudarle a descubrir su propio lente para mirar a los mercados y tianguis y, al mismo tiempo, le sirva para reflexionar sobre el papel del consumo en nuestras vidas cotidianas.Universidad Autónoma del Estado de Méxic

Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease
