NanoCLUST is an analysis pipeline for the classification of amplicon-based full-length 16S rRNA nanopore reads. It characterized by unsupervised read clustering step, based on Uniform Manifold Approximation and Projection (UMAP), followed construction a polished subsequent Blast classification. Here, we demonstrate that performs better than other state-of-the-art software in characterization two commercial mock communities, enabling accurate bacterial identification abundance profile...
ABSTRACTThe emergence of the Omicron SARS-CoV-2 variant concern has changed COVID-19 scenario as this is characterized by high transmissibility and immune evasion ability. To evaluate impact on Canary Islands (Spain) population, we determined reinfection rates disease severity associated with sublineages previously circulating variants concern. We performed a retrospective observational study 21,745 viral genomes collected from December 2020 to July 2022 in (Spain). compared between lineages...
Allelopathy is defined as the effects (stimulatory and inhibitory) of a plant on development neighboring plants through release secondary compounds. Autoallelophaty beneficial or harmful effect species itself. The allelopathic potential belonging to native could induce biotic resistance against invasive plants, whereas allelochemicals released by exotic favor establishment (invasional meltdown). aim our study was examine four target Ludwigia hexapetala using two experiments. In first...
We studied the effect of waterbirds on submerged macrophyte Ruppia maritima in eleven fish ponds within Doñana Natural Park (SW Spain). Separate exclosure designs allowed us to exclude flamingos or all from 3×3 m plots and compare them with control plots. Four experiments were conducted for three month periods at different points annual cycle varying bird densities. Flamingos wildfowl (ducks coot) had significant negative additive effects presence aboveground (leafs shoots) belowground...
Little is known about the effects of waterbirds on benthic macroinvertebrates in nontidal habitats. We conducted 4 waterbird-exclusion experiments a transformed marshland Doñana Natural Park (southwestern Spain) and compared 3 × 3-m control (no exclusion) test plots from which Greater Flamingos Phoenicopterus ruber or all were excluded. The experimental periods coincided with waterbird breeding season (summer), postbreeding period (autumn), wintering (winter), pre- early (spring). Densities...
The release of allelochemicals by plants can affect the performance other organisms positively or negatively. We tested effects aqueous extracts and leachates derived from leaves roots invasive water primrose (Ludwigia hexapetala) on one submerged native species – Ceratophyllum demersum, two exotic Egeria densa emergent growth form Myriophyllum aquaticum. effect Ludwigia hexapetala photosynthetic yield, (i.e. relative rate, leaf area), root length, length lateral shoots each were analysed in...
The study of microbial communities and their applications have been leveraged by advances in sequencing techniques bioinformatics tools. Oxford Nanopore Technologies long-read nanopores provides a portable cost-efficient platform for assays. While this opens the possibility outside specialized environments real-time analysis data, complementing existing efficient library preparation protocols with streamlined bioinformatic workflows is required.Here we present NanoRTax, Nextflow pipeline...
Abstract During a study of five artificial brackish ponds situated in Doñana Natural Park and the Guadalquivir delta between July 2001 June 2002, total six copepod species (two calanoids, three cyclopoids one harpacticoid) were recorded. All them are typical or estuarine habitats. The calanoid Acartia tonsa (originally from North America) was present all studied. This exotic has been found previously European estuaries, but not recorded wetlands. Both relative absolute abundance varied...
ABSTRACT Procambarus clarkii , one of the most invasive aquatic species worldwide, is present in Mediterranean estuarine regions. Water management these deltas involves massive freshwater inputs, reducing wetland salinity and altering natural flooding periods, two important factors for P. . The paper examines whether water affects distribution reproduction success was sampled Camargue every 6 weeks throughout a whole year. Forty‐eight stations were to represent available habitats types study...
Most causal variants of Mendelian diseases are exonic. Whole-exome sequencing (WES) has become the diagnostic gold standard, but causative variant prioritization constitutes a bottleneck. Here we assessed an in-house sample-to-sequence pipeline and benchmarked free tools for germline from WES data. 61 unselected patients with known genetic disease cause was obtained. Variant prioritizations were performed by diverse recorded to obtain yield when present in first, fifth, 10th top rankings. A...
Acute respiratory distress syndrome (ARDS) is an inflammatory process of the lungs that develops primarily in response to pulmonary or systemic sepsis, resulting a disproportionate death toll intensive care units (ICUs). Given its role as critical activator and innate immune responses, previous studies have reported increase circulating cell-free mitochondrial DNA (mtDNA) biomarker for fatal outcome ICU. Here we analyzed association whole-blood mtDNA (wb-mtDNA) copies with 28-day survival...
We studied three commonly used bioindicator groups: phytoplankton, phytobenthos and benthic invertebrate communities' structure patterns in transitions between lotic lentic habitats as consequences of two consecutive large dams constructed the early twentieth century on intermediate reach a lowland river Normandy (NW, France), Selune. According to sampling station position along river, including reservoir lakes, we defined sorts transitions, from upstream downstream: transition (hereafter...
Introduction Ecological restoration through dam removals receives increasing attention from scientists, environmental managers and policy makers. However, most removal projects focus on small structures (< 10 m in height) few ecosystem compartments at a time (e.g. river morphology, reservoir sedimentation, aquatic invertebrates, terrestrial vegetation), but rarely riparian ecosystems simultaneously. Methods We explored the joint taxonomic recovery (temporal patterns α- β-diversity) of...
The contribution of two basal energy sources – detrital organic matter and primary producers as part aquatic food webs varies typically along river continua. A host barriers to flow increase the water residence time sediment nutrient retention in reservoirs worldwide, potentially alter balance between detritus-based algae-based pathways downstream webs. We explored this issue on Sélune River (Normandy, France), a small coastal stream that drains an agricultural catchment with high runoff....
The removal of the two dams on Sélune River since 2019 has led to profound changes in aquatic ecosystem. Lentic habitats bordered by forest had shifted new conditions (running water and sparsely vegetated riverbanks) therefore shaping organisms’ assemblies. We studied how reestablishment lotic interaction with riparian vegetation could mediate restoration important ecological functions river. Six stations located along river continuum were surveyed for 3 years after dam removal: control...
The prevalence of asthma symptoms in Canary Islanders, a southwestern European population from Spain, is almost three times higher than the country average. Because genetic risks identified so far explain <5% heritability, here we aimed to discover new loci by completing first admixture mapping study Islanders leveraging their distinctive makeup, where significant northwest African influences coexist diversity landscape. A 2-stage was conducted 1,491 unrelated individuals self-declaring...
