Comparisons of image-matching software when identifying pool frog (Pelophylax lessonae) individuals from a reintroduced population

Photographic identification of individual animals is a non-invasive and cost-effective method that can provide demographic information on wild populations. This study aims to compare two photo-matching algorithms (Wild- ID I3S-Spot) using reintroduced population pool frogs (Pelophylax lessonae) in the UK as case study. We compared following parameters 1) sex age, 2) image quality, 3) collection size 4) processing time evaluate successful match rates. There were no significant differences rates found between age groups. Wild-ID was more sensitive quality than I3S-Spot. negative relationship for I3S-Spot, however, such Wild-ID. The findings our be used by conservation practitioners reduce workload improve accuracy during monitoring activities.
