The Doria tree kangaroo ( Dendrolagus dorianus ) from New Guinea is a species from the genus of the tree kangaroo ( Dendrolagus ), which comprises around 12 species .

Appearance

The Doria tree kangaroo has a long, dense, red-brownish colored fur without silver tint. It has black ears, a swirl of hair in the middle of the back, and a light brown to cream-colored tail. As one of the largest tree kangaroos, it has a tail length of 44–66 cm and is up to 78 cm long (excluding the tail). The average weight of the males is 13.3 kilograms and the females 10.2 kilograms. One specimen kept in captivity weighed 18 kilograms. A specimen caught in the wild holds the record of all tree kangaroos with a maximum body weight of 20 kilograms. It has a stocky build and long claws, giving it a bear-like appearance.

distribution

Distribution area of ​​the nominate form of the Doria tree kangaroo

The Doria tree kangaroo is found only on the Indo-Pacific island of New Guinea and is endemic to Papua New Guinea . It lives in the southeastern parts of the island, in the mountains and mountain valleys of New Guinea at altitudes of 600 to 3,650 meters, where tropical rainforest , cloud forest and cloud forest grow.

Doria tree kangaroos are no longer kept in Europe. Former owners in Germany are Frankfurt, Karlsruhe, Mannheim, Munich and Stuttgart. Wilhelma was one of the most successful owners in all of Europe.

Way of life

Like all tree kangaroos, it usually looks for food in the treetops, but occasionally also comes to the ground. Recent studies show that the Doria tree kangaroo and other short-tailed species are relatively frequent on the ground. The Doria tree kangaroo moves on the ground mainly bipedal and in small hops. It feeds on leaves, fruits, buds and flowers.

Although the animal lives as a loner , couples can be found during the mating season who spend about a week together. After a gestation period of around 30 days, the baby will suck on the teat in the mother's pouch after birth, where it will spend up to 10 months.

Systematics

The Doria tree kangaroo is classified as an independent species within the genus of tree kangaroos ( Dendolagus ), which currently consists of 12 species. The first scientific description comes from the Australian zoologist and curator at the Australian Museum Edward Pierson Ramsay from 1883, who described the species on the basis of individuals from the interior of New Guinea from the Wondiwoi Peninsula on the border between Papua New Guinea and Indonesia. Ramsey obtained the fur of the animal along with the hides of numerous birds from Papua from a local seller and provisionally described the species, naming it after the Italian zoologist Giacomo Doria .

Within the species, four subspecies were distinguished together with the nominate form :

The last two are now considered to be separate species.

Status, threat and protection

The Doria tree kangaroo is classified by the International Union for Conservation of Nature and Natural Resources (IUCN) as Vulnerable. This is justified with the sharp decline in stocks, which are forecast to reduce by more than 30% over the next three generations and thus around 30 years. The main reason for the decline due to habitat loss due to heavy logging and the associated lack of habitats. In addition, the species is under strong hunting pressure from the population, who value them as a source of meat and hunt them with dogs.
