A number of studies have illustrated the utility of environmental DNA (eDNA) for detecting marine vertebrates. However, little is known about the fate and transport of eDNA in the ocean, thus limiting the ability to interpret eDNA measurements. In the present study, we explore how fate and transport processes affect oceanic eDNA in Monterey Bay, California, USA (MB). Regional ocean modeling predictions of advection and mixing are used for an approximately 10,000 km2 area in and around MB to…

Environmental DNA (eDNA) studies have burgeoned over the last two decades and the application of eDNA has increased exponentially since 2010, albeit at a slower pace in the marine system. We provide

Environmental DNA (eDNA) quantification and sequencing are emerging techniques for assessing biodiversity in marine ecosystems. Environmental DNA can be transported by ocean currents and may remain

Quantification of eDNA to Map the Distribution of Cold-Water Coral Reefs

An effective management of vulnerable marine ecosystems is dependent on thorough knowledge of their location. Multibeam bathymetric mapping and targeted remotely operated vehicle (ROV) surveys are

How to design optimal eDNA sampling strategies for biomonitoring in river networks

Computer simulations are performed to identify best-practice criteria for the choice of positioning of eDNA sampling sites in river networks and identify best practices for sampling site selection for taxa that have a scattered versus an even distribution across the network.

Feasibility Study for Seagrass Beds Monitoring Using Environmental DNA

Environmental DNA (eDNA) is DNA collected directly from environmental samples (soil, sediment, water, air, etc.) rather than from individual organisms. When organisms interact with the environment,

Systematic review and meta‐analysis: Water type and temperature affect environmental DNA decay

Environmental DNA (eDNA) has been used in a variety of ecological studies and management applications. The rate at which eDNA decays has been widely studied but at present it is difficult to

Forensics Meets Ecology – Environmental DNA Offers New Capabilities for Marine Ecosystem and Fisheries Research

Climatic changes and anthropogenic pressures affect biodiversity and community composition. These biodiversity shifts are recognized in marine ecosystems, but the underlying processes are barely



Modelling the transport of environmental DNA through a porous substrate using continuous flow-through column experiments

EDNA behaves anomalously, displaying characteristics of a heterogeneous, polydisperse substance with particle-like behaviour that can be filtered by the substrate, which may influence the interpretation eDNA detection in biological systems.

Persistence of marine fish environmental DNA and the influence of sunlight

It is concluded that sunlight is not the main driver of fish eDNA decay in the experiments, and there are clearly temporal effects that need to be considered when interpreting information obtained using eDNA approaches.

Persistence of environmental DNA in marine systems

This study suggests that environmental DNA can be reliably detected for two days, providing an optimal time window of high local fidelity, and estimates that eDNA may be detected for around 48 h, offering potential to collect ecological community data of highLocal fidelity.

Tracking apex marine predator movements in a dynamic ocean

It is shown that top predators exploit their environment in predictable ways, providing the foundation for spatial management of large marine ecosystems, and critical habitats across multinational boundaries are identified.

Environmental DNA (eDNA) Shedding and Decay Rates to Model Freshwater Mussel eDNA Transport in a River.

It is determined that eDNA shedding was statistically similar across mussel densities, but that first-order decay constants varied between experimental treatments, and a model is presented that can be used as a complementary tool to estimate mussel density.

Particle size distribution and optimal capture of aqueous macrobial eDNA

The results suggest that aqueous macrobial eDNA predominantly exists inside mitochondria or cells, and that settling may therefore play an important role in its fate.

Quantification of Environmental DNA (eDNA) Shedding and Decay Rates for Three Marine Fish.

Novel Taqman qPCR assays are designed for three ecologically and economically important marine fish-Engraulis mordax (Northern Anchovy), Sardinops sagax (Pacific Sardine), and Scomber japonicas (Pacific Chub Mackerel) and a simple mass-balance model is derived to estimate fish abundance from eDNA concentration.
