We feldtested our method in the largest green turtle nesting location in Africa, on Poilão Island i Guinea-Bissau, where it proved to be quick to apply and easy to detect, and non-disruptive for the turtles. We effectively marked 2719 individuals, with some marks lasting up to 13 days. We propose that this protocol can be adapted for other animal groups and in other environmental settings.engjournal article
