This study uses environmental DNA metabarcoding to assess how pumping stations affect European eel distribution and fish species richness in wetland catchments.

The paper uses eDNA metabarcoding to assess the impact of beaver recolonisation on migratory fish distribution across a catchment, finding no negative effects on salmon or lamprey but a positive association with eel.

This study uses eDNA metabarcoding to show that beaver dams increase beta diversity and macroinvertebrate gamma diversity in freshwater systems.

This study compares eDNA metabarcoding and qPCR for detecting European eel in river catchments, finding metabarcoding more effective for broader ecological insights despite slightly lower sensitivity.

This study uses a process-based model to predict seasonal eDNA transport in a river, showing longer transport distances in winter and shorter in summer for Eurasian beavers.

This paper introduces a framework to estimate confidence in absence (CIADM) for priority species using environmental DNA data, showing that increased replication improves confidence in absence assessments.

This study examines seasonal changes in fish eDNA signals across different river types, finding inconsistent patterns and highlighting the importance of considering priority species in survey design.

This study uses environmental DNA metabarcoding to track the spatial and temporal patterns of Arctic charr spawning in a lake, confirming its effectiveness compared to traditional methods.

The paper compares traditional and eDNA methods for detecting quagga mussels, finding that targeted PCR and metabarcoding outperform kick-net sampling, with qPCR being most sensitive at low densities.

This study shows that eDNA metabarcoding read counts correlate with fish biomass and abundance in ponds, and results are consistent across different DNA capture methods.

This study evaluates eDNA metabarcoding for detecting terrestrial mammals in pond water, finding uneven distribution in natural ponds and detection of species missed by other methods.

This study uses eDNA metabarcoding to show that eDNA from introduced fish species peaks within days and degrades quickly, indicating localized and transient eDNA signals in ponds.

This study develops an eDNA qPCR assay for detecting crucian carp in UK ponds and evaluates its effectiveness compared to traditional methods.

This study compares eDNA metabarcoding and targeted qPCR for detecting the great crested newt, finding qPCR more sensitive but metabarcoding with no threshold comparable at a stringent qPCR threshold.
