Finding Fish By Molly Czachur Marine biodiversity is a rich and colourful display of what the natural world has to offer. Whilst large whale sharks are gliding through the oceans, the nearby coastal mangrove forests are acting as a vital nursery ground that is teeming with the microscopic larvae of future fish generations. The closer…

My entry below, named “Finding fish“, illustrates our environmental DNA research through cartoon! This exciting work is being carried out in the von der Heyden lab at Stellenbosch University, South Africa, in collaboration with the Molecular Ecology…

Exciting new tool for marine conservation: environmental DNA

Fish and other aquatic animals shed DNA into the surrounding water. This means that seawater is filled with the DNA of the animals living there, and this is known as environmental DNA (eDNA). Scientists have used environmental DNA to study a range of animals, from earlier eDNA studies in 2008 (e.g. on the invasive American Bullfrog),…
