Abstract:

We document eight cases of axanthism in Green Frogs (Lithobates clamitans) and one case in an American Bullfrog (Lithobates catesbeianus) in Maine. Although this mutation has been previously reported for both species, this is the first confirmed documentation of “blue” L. clamitans and L. catesbeianus from Maine.

Abstract:

The axanthic mutant in the Mexican axolotl (Ambystoma mexicanum) was analysed with respect to the differentiation of pigment cells. Transmission electron micrographs revealed the presence of melanophores and cells that are described as unpigmented xanthophores in axanthic skin. Iridophores apparently failed to differentiate in axanthic axolotls (a pattern similar to that observed in melanoid axolotls). Chromatographic analyses of skin extracts confirmed that there are no pteridines (xanthophore pigments) in axanthic skin, suggesting that the axanthic gene may affect pteridine biosynthesis at s

Abstract:

AbstractPterin pigments are responsible for many of the bright colors observed across the animal kingdom. However, unlike melanin, the genetics of pterin‐based pigmentation has received relatively little attention in animal coloration studies. Here, we investigate a lineage of axanthic ball pythons (Python regius) found in captivity as a model system to study pterin pigmentation in vertebrates. By crowdsourcing shed skin samples from commercial breeders and applying a case–control study design, we used whole‐genome pool sequencing (pool‐seq) and variant annotation. We identified a premature st

Abstract:

Axanthism in amphibians is a relatively rare color aberration reported less often than leucism or albinism. It is caused by lack of specific types of pigment cells in the skin, namely xanthophores, erythrophores, and iridophores. Here, we present the first case of occurrence of this aberration in a widely distributed toad of the green toad (Bufotes viridis) complex and provide an extensive review of axanthism occurrence in amphibians. So far it has been reported in more than 20 species from nine families of amphibians with the highest occurrence in the family Ranidae.

Abstract:

The finding of a young adult slow worm, coloured black-blue, from the upper Eisack Valley / Valle Isarco (South Tyrol / Alto Adige [Italy]) is reported. The colouring is attributed to a lack of yellow colour pigments (axanthism). Potential advantages and disadvantages that arise from the colouration are discussed. It is believed that the unusual colouration is due to a spontaneous mutation. At the time of writing this article the specific status of the slow worm occurring in this region is not known. It could be either a specimen of Anguis fragilis Linnaeus, 1758 or one of Anguis veronensis Po

Abstract:

The salamander family Sirenidae is composed of two extant genera, Siren and Pseudobranchus, each with two known species. Several questions regarding Sirenidae life history persist, and much of the available life history data for Pseudobranchus are attributed to studies of P. axanthus in northern Florida. Information on the reproductive biology of P. axanthus is limited, and historical references often suggest contradictory results. This study was undertaken to clarify information and expand on the limited data regarding P. axanthus reproductive biology, specifically for southern Florida pop
