| Popis: | Moor frog Rana arvalis is widespread in Poland and its geographic range spans from Central Europe up to Siberia, but any records of albinism are rare in the species. Freshly laid albino spawn of moor frogs was observed during nocturnal fieldwork near the village of Lubosz, north-western Poland, in spring 2016. We noted the further development of eggs, but no albino tadpoles nor metamorphs were found later during the season. Both albinism and transient albinism have been noted in the species, this being the first observation from Poland. Atypical pigmentation impairs cryptic function of body colouring and might affect survival. The observation comes from a large frog population in a relatively undisturbed habitat, and thus it adds to the body of literature concerning the background level of abnormalities in amphibian populations. |
