Scientists have found a way of capturing DNA from snow tracks — a promising non-invasive method of monitoring elusive animals like polar bears. Polar bears are icons of the Arctic, elusive and vulnerable. Detailed monitoring of their populations is crucial for their conservation — but because pol

As rising temperatures threaten the Arctic mammals, scientists are turning to new, non-invasive methods to study them
Researchers used the footprint's environmental DNA to monitor elusive polar bears and snow leopards, which are threatened by climate change. Read here.
Counting polar bears isn’t easy, but it’s critical to monitor their survival, so a new approach – to extract DNA from their footprints – might help.
Researchers have developed a non-invasive form of DNA analysis using skin cells shed in the bears’ footprints in the snow.
