Abstract Genetic diversity is critical for adaptation in response to changing environments and provides a valuable metric predicting species’ extinction risk. The International Union Conservation of Nature (IUCN) broader scientific community have acknowledged that genetic component biodiversity conservation. However, there remain gaps the incorporation or application data risk assessments. Here, we describe how metrics can inform species Specifically, focus on information gained from...
This study reports complete plastome sequences for six species of Neotropical Cranichideae and focuses on identification the most variable regions (hotspots) in this group orchids. These structure these plastomes is relatively conserved, exhibiting lengths ranging between 142,599 to 154,562 bp with 36.7% GC average typical quadripartite arrangement (LSC, SSC two IRs). Variation detected LSC/IR SSC/IR junctions explained by loss ndhF ycf1 length variation. For genera epiphytic clade...
Abstract Population demographic changes, alongside landscape, geographic and climate heterogeneity, can influence the timing, stability extent of introgression where species hybridise. Thus, quantifying interactions across diverged lineages, relative contributions interspecific genetic exchange selection to divergence at genome‐wide level is needed better understand drivers hybrid zone formation maintenance. We used seven latitudinally arrayed transects quantify climate, geography landscape...
The COVID-19 pandemic has caused significant supply shortages worldwide for SARS-CoV-2 molecular diagnosis, like RNA extraction kits.The aim of our study was to evaluate the clinical performance and analytical sensitivity a simple diagnosis protocol based on heat shock without using both "CDC" (N gene) "Charite" (E RT-qPCR protocols.1,036 nasopharyngeal samples, 543 them positive, were analyzed. method correctly identified 68.8% (232/337) 89.4% (202/226) positive samples N gene E gene,...
Ecuador had substantial COVID-19-mortality during 2020 despite early implementation of non-pharmaceutical interventions (NPIs). Resource-limited settings like have high proportions informal labour which entail human mobility, questioning efficacy NPIs. We performed a retrospective observational study in Ecuador's national reference laboratory for viral respiratory infections March 2020-February 2021 using stored specimens from 1950 patients, corresponding to 2.3% all samples analysed within...
On January 5 2021, Ecuadorian COVID-19 genomic surveillance program detected a suspicious case of the B.1.1.7 lineage (alpha variant) SARS-CoV-2 in Los Rios province, later confirmed by genome sequencing. The patient travelled from UK end December 2020. By contact tracing, several new cases were confirming transmission and spreading Ecuador.
Changes in telomere length are increasingly used to indicate species’ response environmental stress across diverse taxa. Despite this broad use, few studies have explored plants. However, rapid advances sequencing approaches and bioinformatic tools now allow estimation of using whole genome (WGS) data. Thus, evaluation new for measuring plants needed. Traditionally, has been quantified quantitative polymerase chain reaction (qPCR). While WGS extensively humans, no study date compared the...
Abstract Changes in telomere length are increasingly used to indicate species' response environmental stress across diverse taxa. Despite this broad use, few studies have explored plants. Thus, evaluation of new approaches for measuring telomeres plants is needed. Rapid advances sequencing and bioinformatic tools now allow estimation content from whole‐genome (WGS) data, a proxy length. While has been quantified extensively using quantitative polymerase chain reaction (qPCR) WGS humans, no...
Abstract Ecuador was an early COVID-19 hotspot with substantial COVID-19-mortality. In developed countries, low socioeconomic status is associated infection and compliance non-pharmaceutical interventions (NPIs). However, if NPI were successful in resource-limited settings high human mobility informal labour still unclear. We performed a retrospective observational molecular serological study of Ecuador’s reference laboratory. tested 1,950 respiratory samples from surveillance for SARS-CoV-2...
