The introduction of freshwater fish species is a leading cause of aquatic biodiversity erosion and can spread parasites to native populations. Hidden diversity evidenced by recent taxonomic revisions can add further complexity to the issue by rendering biological assessment data incomplete. The Eurasian minnows Phoxinus are one such example of cryptic diversity, with several described species being invasive. Current non-native...
Development and physical characteristics of the Irish shelf-edge Macnas Mounds, Porcupine Seabight, NE AtlanticNARA Subscribed
Modern cold-water corals (CWCs) occur in a wide range of water depths, with Desmophyllum pertusum being one of the most common species. Pleistocene, Holocene, and modern coral mound formation by living CWC reefs have previously been described in the Porcupine Seabight from water depths greater than 700 m in the vicinity of the transitional zone between the Eastern North Atlantic Water and Mediterranean Outflow Water. Here we d...
Opportunistic use of catecholamine neurotransmitters as siderophores to access iron by Pseudomonas aeruginosaNARA Subscribed
Summary Iron is an essential nutrient for bacterial growth and the cause of a fierce battle between the pathogen and host during infection. Bacteria have developed several strategies to access iron from the host, the most common being the production of siderophores, small iron‐chelating molecules secreted into the bacterial environment. The opportunist pathogen Pseudomonas aeruginosa produces two siderophores, pyoverdine and p...
Whole‐genome sequencing of non‐model organisms is now widely accessible and has allowed a range of questions in the field of molecular ecology to be investigated with greater power. However, some genomic regions that are of high biological interest remain problematic for assembly and data‐handling. Three such regions are the major histocompatibility complex (MHC), sex‐determining regions (SDRs) and the plant self‐incompatibili...
RT-qPCR detection of SARS-CoV-2 RNA still represents the method of reference to diagnose and monitor COVID-19. From the onset of the pandemic, however, doubts have been expressed concerning the sensitivity of this molecular diagnosis method. Droplet digital PCR (ddPCR) is a third-generation PCR technique that is particularly adapted to detecting low-abundance targets. We developed two-color ddPCR assays for the detection of fo...
Foster rather than biological parental telomere length predicts offspring survival and telomere length in king penguinsNARA Subscribed
Because telomere length and dynamics relate to individual growth, reproductive investment and survival, telomeres have emerged as possible markers of individual quality. Here, we tested the hypothesis that, in species with parental care, parental telomere length can be a marker of parental quality that predicts offspring phenotype and survival. In king penguins ( Aptenodytes patagonicus ), we experimentally swapped the single...
CARBIOSOL : Biological indicators of soil quality and organic carbon in grasslands and croplands in Wallonia, BelgiumNARA Subscribed
The protection of agricultural soil quality is critical to environmental sustainability and requires relevant indicators. Total soil organic carbon ( SOC ) is of importance for soil quality but its slow dynamic and inherent variability do not allow early detection of changes. The project CARBIOSOL provides a data set from agricultural soils in Wallonia (Southern Belgium), of total SOC , SOC fractions and biological indicators,...
Low-Cost UAV for High-Resolution and Large-Scale Coastal Dune Change Monitoring Using PhotogrammetryOA Marine
In this paper, coastal dune data are collected at Truc Vert, SW France, using photogrammetry via Unmanned Aerial Vehicles (UAVs). A low-cost GoPro-equipped DJI Phantom 2 quadcopter and a 20 MPix camera-equipped DJI Phantom 4 Pro quadcopter UAVs were used to remotely sense the coastal dune morphology over large spatial scales (4 km alongshore, i.e., approximately 1 km2 of beach-dune system), within a short time (less than 2 h o...
