The coppery brushtail possum (Trichosurus johnstonii) is a species of marsupial possum in the family Phalangeridae. [2] Coppery brushtails are found within the Atherton Tablelands area of Queensland, in northeastern Australia. [1] [2] These mammals inhabit rainforest ecosystems, living within the tree canopy. Though they have a restricted distribution, they are locally common. [2] This population is often considered a subspecies of T. vulpecula . [1]

Description

Coppery brushtail possums have a typical length of 40–49 cm (16–19 in) and weigh 1.2–1.8 kg (2.6–4.0 lb), with males being larger and heavier than females. [3] [4]

Ecology

Like the common brushtail possum, coppery brushtails are nocturnal, and live in dens, which are usually tree hollows. At night, they still spend half of their time resting to conserve energy, and the other half in foraging. [5] In feeding experiments, in selecting their food, these possums may tend to select a mix of plant materials with detoxification requirements that are correlated or independent, rather than contradictory, thus maximizing their ability to process harmful plant byproducts. [6]

Dominance among individuals tends to place females above males, and larger over smaller individuals. [7]

Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas. However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos.

<span class="mw-page-title-main">Poison shyness</span>

Poison shyness, also called conditioned food aversion, is the avoidance of a toxic substance by an animal that has previously ingested that substance. Animals learn an association between stimulus characteristics, usually the taste or odor, of a toxic substance and the illness it produces; this allows them to detect and avoid the substance. Poison shyness occurs as an evolutionary adaptation in many animals, most prominently in generalists that feed on many different materials. It is often called bait shyness when it occurs during attempts at pest control of insects and animals. If the pest ingests the poison bait at sublethal doses, it typically detects and avoids the bait, rendering the bait ineffective.

The greater gliders are three species of large gliding marsupials in the genus Petauroides, all of which are found in eastern Australia. Until 2020 they were considered to be one species, Petauroides volans. In 2020 morphological and genetic differences, obtained using diversity arrays technology, showed there were three species subsumed under this one name. The two new species were named Petauroides armillatus and Petauroides minor.

<span class="mw-page-title-main">Brushtail possum</span> Genus of marsupials

The brushtail possums are the members of the genus Trichosurus in the Phalangeridae, a family of marsupials. They are native to Australia and some small nearby islands. Unique among marsupials, they have shifted the hypaxial muscles from the epipubic to the pelvis, much like in placental muscles, meaning that their breathing cycle is more similar to the latter than to that of other non-eutherian mammals. In general, they are more terrestrially oriented than other possums, and in some ways might parallel primates.

The Phalangeridae are a family of mostly nocturnal marsupials native to Australia, New Guinea, and Eastern Indonesia, including the cuscuses, brushtail possums, and their close relatives. Considered a type of possum, most species are arboreal, and they inhabit a wide range of forest habitats from alpine woodland to eucalypt forest and tropical jungle. Many species have been introduced to various non-native habitats by humans for thousands of years.

In 2021 Wehi was awarded the Hill Tinsley Medal.

Wobbly Possum Disease is a fatal neurological condition of the brushtail possum, first reported in 1995. Symptoms include a stumbling gait, tremors, blindness, activity during the daytime, and falling from trees. The disease is believed to be caused by a virus.
