Characterizing mitochondrial copy number variation and PCR amplification bias as sources of quantitative constraints in DNA metabarcoding

COI metabarcoding of 81 arthropod mock communities shows PCR amplification bias is taxon-specific but non-exponential, so cycle calibration fails while a constant-bias model recovers mtDNA copies.

Charting the insect biodiversity of Crete: insights from a pilot metabarcoding survey

This study uses DNA metabarcoding to survey insect biodiversity in Crete, revealing many new species and highlighting gaps in reference databases.

Environmental DNA metabarcoding of invertebrate-incubated water supports WFD-compliant and animal-friendly bioassessment with added trait insights

This study evaluates two eDNA metabarcoding approaches for stream bioassessment under the WFD, finding they produce comparable ecological status results to bulk DNA and morphology-based methods.

Complex compositional and cellular response of river sediment microbiomes to multiple anthropogenic stressors

This study shows river sediment microbiomes are highly sensitive to reduced flow velocity, leading to altered community compositions and stress responses that recover after two weeks.

Assessment of microphytobenthos communities in the Kinzigcatchment using photosynthesis-related traits, digital light microscopy and 18S-V9 amplicon sequencing

The paper assesses microalgae communities in the Kinzig River catchment using photosynthesis-related traits, digital light microscopy, and 18S-V9 amplicon sequencing, finding conductivity, temperature, pH, and phosphate significantly affect community composition.

Multiple stressor effects on organic carbon degradation and microbial community composition in urban river sediments in a mesocosm experiment

This study examines how salinity and temperature changes affect microbial DOC degradation and community composition in urban river sediments using a mesocosm experiment, finding increased degradation during recovery phases.

Effects of temperature and salinity on microbial degradation of bacterial necromass in urban river sediments in outdoor mesocosm experiments

This study examines how temperature and salinity affect microbial self-recycling of necromass in urban river sediments using mesocosm experiments.

Predicting environmental stressor levels with machine learning: a comparison between amplicon sequencing, metagenomics, and total RNA sequencing based on taxonomically assigned data

This study compares amplicon sequencing, metagenomics, and total RNA sequencing for predicting environmental stressors using machine learning, finding 16S sequencing outperforms others despite moderate performance.
