Papua New Guinea is the largest tropical island in the world and stands out for its wide variety of fauna and flora. New species are discovered every year, making it a very important place of study for the scientific community.
A study published in PNAS states that the Dog-singer-of-New-Guinea (Canis hallstromi) is not extinct as previously thought. “The studies we have done clearly show that the DNA of highland dogs in Indonesia coincides with the singing dogs that we have in captivity”, thus confirming their existence, explains Elaine Ostrander, author of the study.
The specialists considered this species extinct due to the fact that, since the 1970s, they have not been sighted or captured, such as for reasons of loss of life habitat and invasion of other Asian and European dog species.
The group of scientists from the Department of Biology at the University of Cenderawasih, together with experts from other countries, analyzed the DNA of a population of wild dogs and samples of specimens of the species in captivity.
This canid lives at high altitudes on the island of New Guinea, being, in the wild, the largest terrestrial predator in the region. It is distinguished mainly by its vocalization, as the name conveys, which is very characteristic of the species. It is something like a “wolf howl with whale singing tones”, they refer in the article.
