Efficacy of metabarcoding for identification of fish eggs evaluated with mock communities [PDF]

open access: yesEcology and Evolution, 2020
There is urgent need for effective and efficient monitoring of marine fish populations. Monitoring eggs and larval fish may be more informative than that traditional fish surveys since ichthyoplankton surveys reveal the reproductive activities of fish ...

Issues of under-representation in quantitative DNA metabarcoding weaken the inference about diet of the tundra vole Microtus oeconomus [PDF]

open access: goldPeerJ, 2021
During the last decade, methods based on high-throughput sequencing such as DNA metabarcoding have opened up for a range of new questions in animal dietary studies.

The power of metabarcoding: Can we improve bioassessment and biodiversity surveys of stream macroinvertebrate communities? [PDF]

open access: yesMetabarcoding and Metagenomics, 2021
Most stream bioassessment and biodiversity surveys are currently based on morphological identification of communities. However, DNA metabarcoding is emerging as a fast and cost-effective alternative for species identification. We compared both methods in

DNA metabarcoding of spider egg sacs uncovers novel insights into host parasitoid complexes and trophic networks [PDF]

open access: yesScientific Reports
DNA metabarcoding is a rapid tool for sequencing a multitude of samples at once, to identify associated organisms. This pioneering study, using DNA metabarcoding of spider egg sacs, establishes a framework for investigating host-parasitoid associations ...

Evaluating the performance of DNA metabarcoding for assessment of zooplankton communities in Western Lake Superior using multiple markers [PDF]

open access: yesMetabarcoding and Metagenomics, 2021
For DNA metabarcoding to attain its potential as a community assessment tool, we need to better understand its performance versus traditional morphological identification and work to address any remaining performance gaps in incorporating DNA ...

COI Metabarcoding Provides Insights into the Highly Diverse Diet of a Generalist Salamander, Salamandra salamandra (Caudata: Salamandridae)

open access: yesDiversity, 2022
DNA metabarcoding has proven to be an accessible, cost-effective, and non-invasive tool for dietary analysis of predators in situ. Although DNA metabarcoding provides numerous benefits in characterizing diet—such as detecting prey animals that are ...

Identification of Mammalian and Poultry Species in Food and Pet Food Samples Using 16S rDNA Metabarcoding

open access: yesFoods, 2021
The substitution of more appreciated animal species by animal species of lower commercial value is a common type of meat product adulteration. DNA metabarcoding, the combination of DNA barcoding with next-generation sequencing (NGS), plays an increasing ...

Interlaboratory Validation of a DNA Metabarcoding Assay for Mammalian and Poultry Species to Detect Food Adulteration

open access: yesFoods, 2022
Meat species authentication in food is most commonly based on the detection of genetic variations. Official food control laboratories frequently apply single and multiplex real-time polymerase chain reaction (PCR) assays and/or DNA arrays.
