Demographic studies of species, using the photographic mark-recapture method have made big strides as digital cameras and pattern-recognition software have improved. Photographic mark-recapture is non-invasive survey technique that is very cost effective. It comes in very handy to biologists seeking to understand spatial and temporal factors affecting a species’ survival, reproduction, and movements.
Many programmes are available to researchers for mark-recapture studies. The pattern-recognition software program called Wild-ID developed at Dartmouth College is very useful and is a free programme. The program has the lowest pattern identification error rate (less than or equal to 0.007) of any photo-identification system currently available. Wild-ID is a multi-platform application. It requires Java 1.5 or higher. (Most Mac OSX, Windows, and Linux systems satisfy this requirement. The download is the same for all systems.
