Composição, abundância e riqueza de cicadellidae (insecta: hemiptera) em um campus universitário na savana de Bogotá, Colômbia

Despite their importance as disease vectors, there is limited information on the biology and ecology of leafhoppers in Colombia. Therefore, the present study assesses Cicadellidae composition, abundance, and richness at the Military Nueva Granada University (UMNG) campus in Cajicá, Cundinamarca (Colombia), which is located within an exurban rural area. For these purposes, linear insect sweeps were conducted in rectangular fields, 50 meters in length and 2 meters in width, in the following three different areas: short grasslands, tall grasslands, and the Bogotá river bend. Sampling was performed between 11:30 am and 12:30 pm for three weeks between March 2015 and April 2015. The insects were collected using an entomological net and preserved in 70% ethanol. At completion, a total of 2399 individuals had been captured, with Amplicephalus funzaensis and Exitianus atratus being the most abundant species. The composition similarities among the three zones exceeded by 40%, with the greatest similarity recorded between the tall grasslands and the river bend. However, no relationship was found between the number of Cicadellidae species and the number of plant species. In addition, the areas that exhibited the lower species richness were the short grasslands. In fact, the data suggests that frequent grass cutting affects the structure of the Cicadellidae community and increases the abundance of phytoplasmic vectors. Hence, the results provide an approximation of leafhopper composition, abundance, and richness at the UMNG campus, and offers suggestions on how to manage campus traits based on this information.A pesar de su importancia como vectores de patógenos, es escasa la información sobre la biología y la ecología de los cicadélidos en Colombia. Por esta razón, se analizó la composición, la abundancia y la riqueza de Cicadellidae en el campus de la Universidad Militar Nueva Granada (UMNG) en Cajicá, Cundinamarca (Colombia). El campus se encuentra en un contexto rural exurbano. Se realizaron recorridos lineales de 50 m de longitud y 2 m de ancho, en tres zonas diferentes: pastizal corto, pastizal largo y meandro del río Bogotá. Los muestreos se llevaron a cabo entre las 11:30 h y las 12:30 h, durante tres semanas entre marzo y abril del 2015. Los insectos se capturaron con una red entomológica y se preservaron en etanol al 70%. Se capturaron un total de 2399 individuos, y fueron Amplicephalus funzaensis y Exitianus atratus las especies más abundantes. La similitud de la composición entre las tres zonas fue superior al 40% y la mayor similitud se presentó entre el pastizal largo y el meandro. No se encontró correlación entre el número de especies de Cicadellidae y el número de especies vegetales. La zona con menor riqueza fue el pastizal corto. Los datos sugieren que el corte frecuente del pasto afecta la estructura de la comunidad de Cicadellidae e incrementa la abundancia de vectores de fitoplasmas. Los resultados brindan una aproximación sobre la composición, la abundancia y la riqueza de cicadélidos en el campus de la UMNG, y se sugiere de qué manera las características del campus podrían manejarse.Apesar de sua importância como vetores de patógenos, há poucas informações sobre a biologia e a ecologia dos cicadelídeos na Colômbia. Portanto, o presente estudo avaliou a composição, a abundância e a riqueza de Cicadellidae no campus da Universidade Militar Nueva Granada (UMNG) em Cajicá, Cundinamarca (Colômbia). O campus está localizado em uma área rural exurbana. Realizaram-se varreduras lineares à procura de insetos em campos retangulares de 50 m de comprimento por 2 m de largura em três áreas diferentes: prados de grama baixa, de grama alta e no meandro do rio Bogotá. As coletas foram realizadas entre as 11:30 e as 12:30 horas, durante três semanas, entre março e abril de 2015. Os insetos foram coletados usando uma rede entomológica e preservados em etanol a 70%. No total, 2.399 indivíduos foram capturados, com Amplicephalus funzaensis e Exitianus atratus sendo as espécies mais abundantes. A semelhança na composição das três áreas foi superior a 40% e a maior semelhança foi registrada entre os prados de grama alta e o meandro do rio. Não foi encontrada nenhuma relação entre o número de espécies de Cicadellidae e o número de espécies vegetais. As áreas que apresentaram a menor riqueza de espécies foram os prados de grama baixa. Os dados sugerem que o corte frequente da grama afeta a estrutura da comunidade de Cicadellidae e aumenta a abundância de vetores de fitoplasmas. Portanto, os resultados apresentam uma avaliação aproximada da composição, abundância e riqueza de cicadelídeos no campus da UMNG e oferecem sugestões sobre como manejar as características do campus

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Síndrome del burnout en docentes: sus desafíos en tiempos de pandemia

Biodiversidad 2018. Reporte de estado y tendencias de la biodiversidad continental de Colombia

Las cifras y temáticas contenidos en el presente Reporte, aunque no son el panorama completo del estado del conocimiento de la biodiversidad en Colombia, son un compendio seleccionado de los temas que, desde el Instituto Humboldt, consideramos son relevantes y merecen ser discutidos por el público general. En muchos de los casos, las cifras no son esperanzadoras u son un llamado urgente a la acción. En otro casos son la evidencia de que se requieren acciones a nivel nacional, y más allá de esto, son muchas las iniciativas que están germinando desde los territorios, cada vez desde una mayor variedad de actores.Bogotá, D.

The DUNE Far Detector Vertical Drift Technology, Technical Design Report

International audienceDUNE is an international experiment dedicated to addressing some of the questions at the forefront of particle physics and astrophysics, including the mystifying preponderance of matter over antimatter in the early universe. The dual-site experiment will employ an intense neutrino beam focused on a near and a far detector as it aims to determine the neutrino mass hierarchy and to make high-precision measurements of the PMNS matrix parameters, including the CP-violating phase. It will also stand ready to observe supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector implements liquid argon time-projection chamber (LArTPC) technology, and combines the many tens-of-kiloton fiducial mass necessary for rare event searches with the sub-centimeter spatial resolution required to image those events with high precision. The addition of a photon detection system enhances physics capabilities for all DUNE physics drivers and opens prospects for further physics explorations. Given its size, the far detector will be implemented as a set of modules, with LArTPC designs that differ from one another as newer technologies arise. In the vertical drift LArTPC design, a horizontal cathode bisects the detector, creating two stacked drift volumes in which ionization charges drift towards anodes at either the top or bottom. The anodes are composed of perforated PCB layers with conductive strips, enabling reconstruction in 3D. Light-trap-style photon detection modules are placed both on the cryostat's side walls and on the central cathode where they are optically powered. This Technical Design Report describes in detail the technical implementations of each subsystem of this LArTPC that, together with the other far detector modules and the near detector, will enable DUNE to achieve its physics goals
