Phytoplankton Metabarcoding Data Processing

Phytoplankton taxonomy was undertaken using DNA metabarcoding (along with traditional taxonomic approaches via microscopy). The filter samples were extracted for DNA using E.Z.N.A. water DNA kits using the default protocol (Omega Bio-Tek, USA). After extraction, the samples were PCR amplified using the 18s rRNA V9 region with unique dual-tags using the

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus

Journal of Fish Biology, EarlyView.
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

Validating gut flushing as a non‐lethal sampling technique for diet monitoring in agastric fish

Journal of Fish Biology, EarlyView.
Abstract Non‐lethal diet sampling is essential where individual‐level monitoring and welfare matter, yet evidence on season‐long outcomes in agastric fishes is scarce. We tested syringe‐based gut flushing in pond‐reared common carp Cyprinus carpio over one growing season (April–September) using PIT‐tagged fish assigned a priori to three handling ...

Computer Vision Detects an Association Between Gross Gill Score and Ventilation Rates in Farmed Atlantic Salmon (Salmo salar)

Journal of Fish Diseases, EarlyView.
ABSTRACT Poor gill health compromises the health and welfare of farmed Atlantic salmon (Salmo salar) by causing respiratory distress and increased ventilation frequency. Poor gill health is caused by numerous factors, including amoebic gill disease (AGD), jellyfish stings, and toxic algae, and is monitored by fish farmers by manual ‘gill scoring’. Gill

Complementary role of environmental DNA for line-transect bird surveys: A field test in a Japanese rice landscape

Ecological Indicators
Monitoring and conserving bird biodiversity in rice landscapes is a global challenge. Although environmental DNA (eDNA) metabarcoding can potentially provide a sensitive and comprehensive assessment of bird biodiversity in farmlands, there is a lack of ...

Rapid Clearance of Tetracapsuloides bryosalmonae Spores by Freshwater Sponge Ephydatia muelleri: Potential Implications for Controlling Proliferative Kidney Disease in Salmonids

Journal of Fish Diseases, EarlyView.
ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.

The evaluation of shotgun sequencing and rpoB metabarcoding for taxonomic profiling of bacterial communities

BMC Microbiology
Background The importance of microbial community profiling has been increasingly recognized in biological and environmental research. While metabarcoding has been widely used for such analysis by targeting specific DNA sequences as markers, shotgun ...
