Freshwater ecosystems are among the most endangered habitats on Earth, with thousands of animal species known to be threatened or already extinct. Reliable monitoring of threatened organisms is crucial for data-driven conservation actions but remains a challenge owing to nonstandardized methods that depend on practical and taxonomic expertise, which is rapidly declining. Here, we show that a diversity of rare and threatened freshwater animals--representing amphibians, fish, mammals, insects and…

Monitoring Aquatic Biodiversity in the Gulf using Environmental DNA

It is confirmed that seawater samples can contain key information on populations of oceanic species, and demonstrate a general potential of eDNA for studying populations of marine organisms, and provides a strong proof-of-concept for future monitoring of aquatic biodiversity and resources in the Gulf.

Next‐generation monitoring of aquatic biodiversity using environmental DNA metabarcoding

It is argued that the proposed DNA‐based approach has the potential to become the next‐generation tool for ecological studies and standardized biodiversity monitoring in a wide range of aquatic ecosystems.

Quantification of mesocosm fish and amphibian species diversity via environmental DNA metabarcoding

The results illustrate the potential for eDNA sampling and metabarcode approaches to improve quantification of aquatic species diversity in natural environments and point the way towards using eDNA metabarcoding as an index of macrofaunal species abundance.

Environmental DNA for Detection of Endangered Grouper Species (Epinephelus spp.)

Despite the methodological challenges inherent in eDNA analysis, the results demonstrated that eDNA method may be proved to step towards a new beginning to detect and monitor endangered grouper species.

Quantitative monitoring of multispecies fish environmental DNA using high-throughput sequencing

The calculated copy numbers showed significant positive correlation with those determined by quantitative PCR, suggesting that eDNA metabarcoding with standard DNA enabled useful quantification of eDNA, and for samples that show a high level of PCR inhibition, the method might allow more accurate quantification than qPCR.

Zooplankton biodiversity monitoring in polluted freshwater ecosystems: A technical review

Identifying a breeding habitat of a critically endangered fish, Acheilognathus typus, in a natural river in Japan

This study highlights the value of eDNA analysis to guide conventional monitoring surveys and shows that combining both methods can provide important information on breeding sites that is essential for species’ conservation.

Using Environmental DNA to Census Marine Fishes in a Large Mesocosm

Estimating the vertebrate fauna in a 4.5-million-liter mesocosm aquarium tank at the Monterey Bay Aquarium and sequencing the eDNA from its constituent seawater concludes that eDNA has substantial potential to become a core tool for environmental monitoring, but that a variety of challenges remain before reliable quantitative assessments of ecological communities in the field become possible.



Persistence of Environmental DNA in Freshwater Ecosystems

Improve the knowledge on DNA persistence in water in order to confirm the presence of the focus species in freshwater ecosystems and to greatly influence planning of biodiversity inventories and biosecurity surveys.

Species detection using environmental DNA from water samples

A novel approach, based on the limited persistence of DNA in the environment, to detect the presence of a species in fresh water, using specific primers that amplify short mitochondrial DNA sequences to track the existence of a frog in controlled environments and natural wetlands.

“Sight‐unseen” detection of rare aquatic species using environmental DNA

Quantitative comparisons with traditional fisheries surveillance tools illustrate the greater sensitivity of eDNA and reveal that the risk of invasion to the Laurentian Great Lakes is imminent.

Meta‐barcoding of ‘dirt’ DNA from soil reflects vertebrate biodiversity

It is found that DNA from the soil surface reflects overall taxonomic richness and relative biomass of individual species, however, one species that was recently introduced was not detected and animal behaviour was shown to influence DNA deposition rates.

Molecular Detection of Vertebrates in Stream Water: A Demonstration Using Rocky Mountain Tailed Frogs and Idaho Giant Salamanders

The utility of eDNA techniques for detecting aquatic vertebrates in stream systems has been demonstrated across the majority of freshwater systems, setting the stage for an innovative transformation in approaches for aquatic research.

Recovery of DNA and pollen from New Zealand lake sediments

Global diversity of large branchiopods (Crustacea: Branchiopoda) in freshwater

The Branchiopoda are monophyletic, but inter-ordinal relationships, as well as many evolutionary relationships at lower taxonomic levels are still unclear, and ongoing molecular studies will more accurately depict species diversity and phylogenetic patterns.

Freshwater biodiversity: importance, threats, status and conservation challenges

This article explores the special features of freshwater habitats and the biodiversity they support that makes them especially vulnerable to human activities and advocates continuing attempts to check species loss but urges adoption of a compromise position of management for biodiversity conservation, ecosystem functioning and resilience, and human livelihoods.

Ancient DNA reveals late survival of mammoth and horse in interior Alaska

The finding that mammoth and horse overlapped with humans for several millennia in the region where people initially entered the Americas challenges theories that megafaunal extinction occurred within centuries of human arrival or were due to an extraterrestrial impact in the late Pleistocene.

Beringian Paleoecology Inferred from Permafrost-Preserved Fungal DNA

Interestingly, DNA sequences with high homology to sequences of coprophilic and keratinophilic fungi indicated that feces, hair, skin, and nails could have been sources of ancient megafauna DNA recently reported to be present in small amounts of Siberian permafrost sediments.
