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.

Use of dead tree-fern trunks as oviposition sites by the terrestrial breeding frog Leiopelma archeyi

While most anurans lay their eggs in or near water, there is a wide diversity of species that lay their eggs on the ground, under rocks, or in burrows. For these terrestrial-breeding species, identifying the habitat requirements of oviposition sites is particularly useful for conservation and management planning, given that oviposition in anurans is strongly related to the environmental characteristics in which they live. Leiopelma archeyi is an endemic New Zealand frog that reproduces on moist substrates.
