Аннотация:Inventory of color polymorphism in populations of Dendrobates galactonotus (Anura: Dendrobatidae), a poison frog endemic to Brazil.We studied the various color morphs of Dendrobates galactonotus that occur in its range between the Amazon and Tapajós rivers, in the Brazilian states of Pará, Maranhão, northern Mato Grosso, and northern Tocantins.Dorsal coloration ranges from black to light blue and from red via orange to yellow, cream and white, with or without black spots or vermiculations.Most specimens are uniformly black below, but in some populations the color of the back has invaded the ventral surface and the black has been reduced to small areas on the seat patch and under the thighs.We could not locate any completely white populations, a color variant present in captivity and known as "Moonshine."No regularity in the distribution of color pattern could be distinguished; the majority of localities has orange colored populations, but other color morphs are sprinkled between them.Populations are uniform, only showing one color, although the amount of black elements on the back may vary.Threats to this species are deforestation, fragmentation of habitat, hydroelectric projects (already functioning, under construction, or projected), gold mining, and possibly illegal international trade.Although this species is widely distributed in terrariums in Europe, the United States, and Japan, all these specimens stem from illegal exports.Genetic research to try to establish a connection between color pattern and genetic make-up of populations is in progress.
