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), …

How does mangrove carbon offset work?

Areas of coast with mangrove forests benefit from the mangroves supporting large fisheries, and also protecting the shoreline from erosion and sedimentation. Although these benefits are significant to the local …

They were climbing all over the surrounding trees and roofs, and stared at us whilst we ate! It looks like the black-faced vervet monkey …
