Significant advances have been made towards surveying animal and plant communities using DNA isolated from environmental samples. Despite rapid progress, we lack a comprehensive understanding of the “ecology” of environmental DNA (eDNA), particularly its temporal and spatial distribution and how this is shaped by abiotic and biotic processes. Here, we tested how seasonal variation in thermal stratification and animal habitat preferences influence the distribution of eDNA in lakes. We sampled… 

Vertical stratification of environmental DNA in the open ocean captures ecological patterns and behavior of deep‐sea fishes

Establishing the foundations for a sustainable use of deep‐sea resources relies on increasing knowledge on this inaccessible ecosystem, which is challenging with traditional methods. The analysis of

Spatio-temporal variability of eDNA signal and its implication for fish monitoring in lakes

Environmental DNA (eDNA) metabarcoding is revolutionizing the monitoring of aquatic biodiversity. The use of eDNA has the potential to enable non-invasive, cost-effective, time-efficient and

Spatio-temporal monitoring of lake fish spawning activity using environmental DNA metabarcoding

Determining the timing and location of fish reproductive events is crucial for the implementation of correct management and conservation schemes. Conventional methods used to monitor these events are

Leveraging eDNA metabarcoding to characterize nearshore fish communities in Southeast Alaska: Do habitat and tide matter?

It is hypothesized that differences in taxa observed among habitats were largely due to lack of mixing between bottom and surface water, providing further evidence that eDNA transport is minimal and that many marine eDNA detections are derived from highly localized sampling locations.

Freshwater connectivity transforms spatially integrated signals of biodiversity

Aquatic ecosystems offer a continuum of water flow from headwater streams to inland lakes and coastal marine systems. This spatial connectivity influences the structure, function and dynamics of

A quantitative eDNA-based method to monitor fish spawning in lakes: application to European perch and whitefish

There is an urgent need to evaluate the effects of anthropogenic pressures and climatic change on fish populations’ dynamics. When monitored in lakes, the spawning of fish is generally assessed using

Elasmobranch diversity across a remote coral reef atoll revealed through environmental DNA metabarcoding

As elasmobranchs are becoming increasingly threatened, efficient methods for monitoring the distribution and diversity of elasmobranch populations are required. Environmental DNA (eDNA) metabarcoding

Mapping the Distributions of Pacific and Western Brook Lampreys Along the Oregon South Coast using eDNA and Community Science: 2021 Report.

Objective: To collect data on the presence of two lamprey species in Oregon South Coast streams to better understand what habitats these lampreys prefer, create baseline data to assess future changes

Environmental nucleic acids: a field-based comparison for monitoring freshwater habitats using eDNA and eRNA

Nucleic acids released by organisms and isolated from environmental substrates are increasingly being used for molecular biomonitoring. While environmental DNA (eDNA) has received attention recently,

Activity, energy use and species identity affect eDNA shedding in freshwater fish

A positive correlation between target eDNA quantities as measured with digital PCR, fish activity and energy use, as well as species-specific differences between fish species occurring in European freshwaters is demonstrated.



Temporal and spatial variation in distribution of fish environmental DNA in England’s largest lake

Comprehensive spatial sampling of England’s largest lake, Windermere, during summer and winter finds broad consistency between results from three sampling events in terms of species detection and abundance, with eDNA detecting more species than established methods and being significantly correlated to rank abundance determined by long-term data.

Seawater environmental DNA reflects seasonality of a coastal fish community

The utility of eDNA for recovering seasonal variation in marine fish communities, knowledge of which is essential for standardised long-term monitoring of marine biodiversity, is demonstrated.

Aquatic environmental DNA detects seasonal fish abundance and habitat preference in an urban estuary

It is suggested that eDNA will facilitate fine-scale geographic and temporal mapping of marine fish populations at relatively low cost and support further exploration of fish presence in the lower Hudson River estuary.

Environmental DNA metabarcoding of lake fish communities reflects long‐term data from established survey methods

It is demonstrated that eDNA metabarcoding can describe fish communities in large lakes, both qualitatively and quantitatively, and has great potential as a complementary tool to established monitoring methods.

Performance of temperature and dissolved oxygen criteria to predict habitat use by lake trout (Salvelinus namaycush)This paper is part of the series “Forty Years of Aquatic Research at the Experimental Lakes Area”.

We compared theoretical habitat volumes, determined from traditional combinations of temperature and dissolved oxygen concentration (DO) boundaries, with in situ habitat use by acoustically tagged

Assessing vertebrate biodiversity in a kelp forest ecosystem using environmental DNA

This study reports the results of a 2.5 km eDNA transect surveying the vertebrate fauna present along a gradation of diverse marine habitats associated with a kelp forest ecosystem, and presents an explicit accounting of false negatives and positives in metabarcoding data.

Environmental DNA as a ‘Snapshot’ of Fish Distribution: A Case Study of Japanese Jack Mackerel in Maizuru Bay, Sea of Japan

It is concluded that eDNA generally provides a ‘snapshot’ of fish distribution and biomass in a large area and a best-fit model included echo intensity obtained within 10–150 m from water sampling sites, indicating that the estimated eDNA concentration most likely reflects fish biomass within 150 m in the bay.

Transport Distance of Invertebrate Environmental DNA in a Natural River

The results indicate that there may be species' specific transport distances for eDNA and demonstrate for the first time that invertebrate eDNA can persist over relatively large distances in a natural river system.

Spatial distribution of environmental DNA in a nearshore marine habitat

This study serves as a first analysis of diversity at the fine spatial scales relevant to marine ecologists and confirms the promise of eDNA in dynamic environments.

Environmental DNA (eDNA) Detection Probability Is Influenced by Seasonal Activity of Organisms

EDNA was applied to survey for two highly imperiled species endemic to the upper Black Warrior River basin in Alabama, US and found that season strongly affected eDNA detection probability for both species, with N. alabamensis having higher e DNA detection probabilities during the cool season and S. depressus have higher eDNA Detection probability during the warm season.
