Why catch when you can throw? A framework for tagging animals without capture or restraint
Royal Society Open ScienceThe use of electronic tags has significantly advanced our understanding of wild animal behaviour and physiology. However, traditional tagging methods often require capturing and restraining or sedating animals, which causes stress and may potentially ...
