Colour variation and behaviour of the cryptic New Zealand frog Leiopelma archeyi

Understanding the ecology of cryptic species is essential for designing effective monitoring and conservation strategies. Leiopelma archeyi is a native New Zealand frog with cryptic colouration, patterning, and behaviour. Our study examined dorsal colour variation and climbing behaviour in this species. Our first aim was to investigate if L. archeyi demonstrates colour crypsis by background-matching. Secondly, we determined if green pigmentation is lost as frogs age by comparing frog body size (a proxy for age) with the percentage of green on their dorsal surface.
