Apr 28, 2021 · eDNA is a technique that can monitor a particular strain of DNA in a sample. Originally, the technique was used to monitor endangered species, confirming their presence without the use of a camera or the human eye. Now, the technique is also being used to help check for COVID-19 and help stem the spread of the virus.
Dec 13, 2021 · Image: Unsplash/ Geoffrey Baumbach. The ability to identify certain animals living in an environment through environmental DNA, or 'eDNA.' has revolutionized conservation and wildlife monitoring. A recent assessment led by biologist Jun Yang suggested that “eDNA based studies are entering an exciting and rapidly accelerating era."
Jun 8, 2023 · News research finds air-pollution monitors may hold a wealth of biodiversity data. Image: Pexels/Marcin Jozwiak. A new study found that air-quality-monitoring systems, thousands of which are already in place in more than 100 countries, potentially already capture and store environmental DNA, or eDNA. eDNA is the genetic material that is shed ...
Dec 12, 2022 · According to a new report issued this month by UN Environment Programme (UNEP) and partners, international climate goals will be out of reach unless investments into nature-based solutions quickly ramp up to $384 billion per year by 2025, more than double of the current $154 billion per year. This is where nature tech could play a valuable role.
Jun 1, 2022 · The LRAUV is a nimble underwater robot that can travel to remote areas of the ocean for extended periods of time. The ESP is a robotic “laboratory-in-a-can" that filters seawater and preserves eDNA for future study. By equipping an LRAUV with ESP technology, researchers can expand the scale of ocean monitoring over time and space.
Sep 21, 2023 · Analysis of eDNA gives a comprehensive snapshot of the presence and diversity of the species sampled with high accuracy. This data is valuable for a number of reasons, including helping to track endangered species, monitoring diseases and pathogens and, when samples are compared over time, eDNA can provide insights into how the climate crisis is affecting marine life, for example, by shifting ...
Aug 22, 2023 · The eDNA surveys detected a diverse range of species. These included some species (such as algae and fungi) that are not easily detected using other survey methods. The results confirmed the presence of bird species recorded by the cameras but also showed other visiting bird species went undetected by the cameras.
Jul 31, 2023 · A team at Monterey Bay Aquarium Research Institute (MBARI) in California is using long-range autonomous robot submarines to collect eDNA and monitor ocean health. “This DNA soup offers clues about biodiversity changes in sensitive areas, the presence of rare or endangered species, and the spread of invasive species – all critical to understanding, promoting and maintaining a healthy ocean ...
Mar 5, 2024 · Environmental DNA (eDNA): eDNA sampling involves collecting and analyzing DNA traces present in environmental samples, such as water or soil, to detect the presence of species. Advances in eDNA technologies and AI analysis techniques can improve species detection, especially for elusive or cryptic species.
Dec 9, 2020 · This environmental DNA (eDNA) is easy to collect and can help detect organisms that might otherwise be difficult to capture or are in low abundance. The technique has also improved baseline knowledge of coastal biodiversity in other areas of high shipping, a fundamental step in detecting future change.
