Environmental DNA (eDNA) is genetic material that is extracted from the environment without the need to isolate a specific organism. It can be found in samples of soil, water, ice, air or other environments.
Here are some key points about eDNA:
Sample collection: Samples are collected from the environment, and DNA is then extracted and analyzed.

Uses: eDNA is used to detect the presence of species, assess biodiversity and monitor the environment. It can help detect invasive species, rare or endangered species and changes in ecosystems.
Advantages: Using eDNA is more non-invasive and often more efficient than traditional methods for species monitoring and ecosystem assessment.

Technologies: eDNA analyses typically involve techniques such as PCR (polymerase chain reaction) and DNA sequencing.
This technology is able to provide important information about the state and changes in the environment, which makes it extremely valuable for scientific research and nature conservation.
Our goal is to confirm the presence of sturgeon DNA at key locations through such analysis within the #SturNet project. If the results show the presence of specific genes characteristic of sturgeons, this means that they probably inhabit the area from which the sample was taken.
Why is it important?
The non-invasive method for detecting eDNA has several advantages:
Minimal environmental impact: There is no need for direct contact with the animals, which reduces stress and risk to them.
Speed and efficiency: The method is fast and can provide information about the presence of rare or difficult-to-observe species.
Accuracy: The technology is very accurate and can detect even small amounts of eDNA, making it suitable for population monitoring.
Our goal is to use this method to obtain valuable information about sturgeon populations and to support conservation efforts.
