It's a pretty clever way to take stock of who's living where, especially for creatures that are shy or hard to spot.
This method allows for species detection and identification without direct observation. For example, a team might take a water sample from a lake, and from that single sample, they could potentially discover if a rare fish species lives there, even if no one has seen it in years. It really does make wildlife surveys much more efficient, and perhaps, a little less intrusive too.
How Edna Sampling Works
The process of Edna sampling is actually quite simple in concept, though it involves careful scientific steps. First, a field team goes out to a specific location, say, a lake or a stream. They collect environmental samples, most often water, but sometimes soil or even air. For instance, members of a 2019 field team from Pond Inlet and Salluit were filtering Edna from water samples collected from Milne Inlet, which is a good example of this work in action.
Once the samples are gathered, they're brought back to a lab. There, scientists filter the water or process the soil to concentrate the genetic material. After that, they extract the DNA from these concentrated samples. This extracted DNA is then analyzed using special molecular techniques. It's a bit like taking a tiny piece of a puzzle and trying to figure out the whole picture from it, you know?
The analysis involves comparing the detected DNA sequences to known genetic databases. This comparison helps identify the species that shed the DNA. It's a powerful way to monitor biodiversity, track invasive species, or even find endangered ones, all with minimal disturbance to the environment. This whole process, really, is a testament to how far genetic science has come.
