Pseudochirulus cinereus is found only in tropical rainforests in Australia. They are adapted to living at higher elevations, above 300-450 m, and are found on mountaintops. Herbert River ringtail possums (Pseudochirulus herbertensis) are closely related to Daintree River ringtail possums. Herbert River ringtail possums spend most of their time in the canopy of the rainforest, only journeying to the ground on rare occasions. Due to their close relationship, Daintree River ringtail possums may exhibit similar behaviors.
Range elevation: 300 (low) m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest
Daintree River ringtail possums (Pseudochirulus cinereus) are endemic to wet tropical regions in Australasia. These animals are found in northeastern Queensland, Australia, from Thornton Peak (Daintree) to the Carbine Tableland (Queensland Department of Environment and Heritage, 1992) as well as New Guinea, Japan, and the Salawatti Islands (Nowak, 1999).
Biogeographic Regions: australian (Native )
Based on the feeding habits of similar possums, it is reasonable to believe that Daintree River ringtail possums are primarily folivorous. Ringtail possums, including Pseudochirulus cinereus, contain a large caecum with bacteria in order to digest the leaves. Daintree River ringtail possums and other species of ringtail possums may occasionally eat flowers or fruits (Queensland Department of Environment and Heritage, 1992) and exhibit coprophagy (Andromeda Oxford Ltd., 2001).
Plant Foods: leaves; fruit; flowers
Other Foods: dung
Primary Diet: herbivore (Folivore )
Specific parasites of Pseudochirulus cinereus are unknown, however some possible endoparasites may include those in the Phyla Cestoda, Nematoda, and Protozoa (McKay, 1987).
Daintree River ringtail possums are important members of the ecosystems in which they live. The Etolo people of Papua New Guinea will use the possums as food if they capture one during a hunt (Dwyer, 1982).
Positive Impacts: food
Daintree River ringtail possums generally do not live near humans and do not have adverse effects on human economies.
According to the IUCN Red List, Pseudochirulus cinereus is a low risk, near threatened species (Australasian Marsupial & Monotreme Specialist Group, 1996).
US Federal List: no special status
CITES: no special status
Like other ringtail possums, Daintree River ringtail possums are quiet animals. Young ringtail possums, however, may produce a quiet noise when they find themselves separated from their mothers (Queensland Department of Environment and Heritage, 1992). Daintree River ringtail possums may leave feces as a means of chemical communication. They may also leave their scent by rubbing objects with a gland on their sternum ("Ringtail and greater gliding possums", 2004).
Communication Channels: visual ; tactile ; acoustic ; chemical
Other Communication Modes: scent marks
Perception Channels: visual ; tactile ; acoustic ; chemical
Pseudochirulus cinereus is very similar to the Herbert River ringtail possums (Pseudochirulus herbertensis). Due to lack of information on P. cinereus, inferences about these animals were made according to information on Herbert River ringtail possums (Queensland Department of Environment and Heritage, 1992). Daintree River ringtail possums and Herbert River ringtail possums (Pseudochirulus herbertensis) have been treated as the same species previously (Australasian Marsupial & Monotreme Specialist Group, 1996). These possum species differ in color and geographic location; P. cinereus is found north of Herbert River ringtail possum habitat. The two species were separated in 1989 on the premise that they contain different numbers of chromosomes and, therefore, cannot interbreed (Queensland Department of Environment and Heritage, 1992).
According to Wilson and Reeder (2005), the species name for Daintree River ringtail possums has been changed from Pseudocheirus canescens to Pseudochirulus cinereus by Flannery in 1994.
The lifespan of Daintree River ringtail possums in the wild is unknown. Researchers, however, believe that Pseudochirulus cinereus may live longer than their smaller ringtail possum relatives (Springer and Kirsch, 1989). An estimation of the lifespan of P. cinereus may be 4 to 5 years in the wild ("Ringtail and greater gliding possums", 2004) and up to 15 years for captive females (Springer and Kirsch, 1989).
Typical lifespan
Status: wild: 4 to 5 years.
Typical lifespan
Status: captivity: 15 (high) years.
Daintree River ringtail possums are born with dense, woolly fur (Nowak, 1999) of a light brown color, which remains the same as they become adults (unlike Herbert River ringtail possums which become much darker as adults). They have a dark stripe along the back and head. These possums can be distinguished by a pointed snout with a “roman nose” and a tapering tail. Ringtail (Pseudochirulus) possums in general have prehensile tails. Herbert River ringtail possums use their tails to carry small branches for nest making (Queensland Department of Environment and Heritage, 1992). Due to their arboreal lifestyle, the ventral side of the tail of Daintree River ringtail possums is hairless, ensuring a better grip as they climb. They also have hand-like feet that are well suited to life in the canopy (Andromeda Oxford Ltd., 2001).
Males tend to be larger than females. A study concerning anesthetizing Australian possums shows that Daintree River ringtail possum males weigh between 830 and 1450 g, while females range from 700 to 1200 g (Holz, 2002). Exact measurements for the length of P. cinereus were not found, but similar possums range from 167 to 368 mm head and body length (Nowak, 1999).
Range mass: 700 to 1450 g.
Range length: 167 to 368 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
Predators of Pseudochirulus cinereus include wedge-tailed eagles (Aquila audax) in northern Queensland and dingoes (Canis lupus dingo) in northern Australia. Other predators may include owls and pythons.
Known Predators:
There is little information on the reproduction in Pseudochirulus cinereus. Inferences are made according to the reproduction of similar ringtail possums found in similar areas (Springer and Kirsch, 1989). Daintree river ringtail possums probably spend most of their lives alone, only meeting up with members of the opposite sex prior to breeding (Queensland Department of Environment and Heritage, 1992). They are typically polygynous animals but may shift between monogamy and polygyny depending on resource availability ("Ringtail and greater gliding possums", 2004).
Mating System: monogamous ; polygynous
Pseudochirulus cinereus individuals may start reproducing between 18 months and 2 years old (Springer and Kirsch, 1989). Daintree River ringtail possums may breed throughout the year, but mating peaks in April and May. The average litter size is 2 young and breeding occurs once annually. Young may spend 4 to 5 months in their mother's pouch after which they will be carried on her back (Nowak, 1999). Weaning in similar species occurs at 150 to 160 days, and young ringtail possums may become independent at 10 months ("Ringtail and greater gliding possums", 2004). Generation times for pseudocheirids is generally 2 to 4 years. Researchers believe that size may be an important factor in determining the duration of generation time. Because Pseudochirulus cinereus is smaller in size compared to other ringtail possums, they may have a shorter generation time (Springer and Kirsch, 1989).
Breeding interval: Breeding occurs throughout the year but peaks in April and May.
Breeding season: Breeding occurs from April through May.
Range number of offspring: 2 (high) .
Range weaning age: 150 to 160 days.
Range time to independence: 10 (high) months.
Range age at sexual or reproductive maturity (female): 1.5 to 2 years.
Range age at sexual or reproductive maturity (male): 1.5 to 2 years.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Information regarding much of the reproduction of Pseudochirulus cinereus is unknown (Springer and Kirsch, 1989). Females carry the young in their pouches or on their backs (Nowak, 1999), and older young are sometimes left alone on a branch until their mother returns (Queensland Department of Environment and Heritage, 1992). Due to the solitary lifestyle of Daintree River ringtail possumss (Andromeda Oxford Ltd., 2001), males probably do not contribute to providing for or protecting their young.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)

Der Graue Ringbeutler (Pseudochirulus cinereus) ist ein Beutelsäuger aus der Familie der Ringbeutler, der von nur in drei kleinen Gebieten im nördlichen Queensland südöstlich der Kap-York-Halbinsel beheimatet ist. Die drei Regionen sind das Mount Carbine Tableland, das Mount Windsor Tableland und der Thornton Peak.[1][2]
Graue Ringbeutler haben eine Kopf-Rumpf-Länge von 34 bis 37 cm, einen 32 bis 40 cm langen Schwanz und erreichen ein Gewicht von 700 bis 1400 g. Das Fell der Tiere ist am Rücken karamellbraun bis dunkelbraun und wird zum cremefarbenen Bauch hin zunehmend heller. Ein dunkler Streifen beginnt zwischen den Augen und verläuft anschließend entlang der Rückenmitte. Das letzte Drittel des Schwanzes ist normalerweise weiß.[1]
Der Graue Ringbeutler lebt in Regenwäldern in drei kleinen Gebieten in den Wet Tropics of Queensland oberhalb einer Höhe von etwa 420 Metern über dem Meeresspiegel. Die Tiere sind nachtaktiv und verbringen den Tag in Baumhöhlen oder versteckt in großen Epiphytenhaufen. Über das Fortpflanzungsverhalten ist bisher kaum etwas bekannt. Der Beutel der Weibchen enthält zwei Zitzen und somit können die Weibchen maximal zwei Jungtiere gleichzeitig großziehen. Weibchen mit Jungtieren im Beutel oder auf dem Rücken wurden sowohl im Sommer als auch im Winter beobachtet und es scheint keine spezielle Fortpflanzungszeit zu geben.[1]
Graue Ringbeutler ernähren sich von Blättern. Zu den bevorzugten Nahrungspflanzen zählen Alphitonia whitei aus der Familie der Kreuzdorngewächse, Homalanthus novoguineensis und Macaranga subdentata aus der Familie der Wolfsmilchgewächse, Arytera aus der Familie der Seifenbaumgewächse, Niemeyera aus der Familie der Sapotengewächse und die Fiederaralie Polyscias murrayi. Feigen werden ebenfalls gefressen.[1]
Die IUCN klassifiziert den Grauen Ringbeutler in die Kategorie „gering gefährdet“ (Near Threatened). Das Verbreitungsgebiet ist weniger als 1000 km² groß und war in der Vergangenheit möglicherweise größer. Ob die Bestände zunehmen, abnehmen oder auf einem gleichen Niveau bleiben ist nicht bekannt.[2]

The Daintree River ringtail possum (Pseudochirulus cinereus), also known as the cinereus ringtail possum, is a species of possum found in northeastern Queensland, Australia. It was long believed to be the same as the Herbert River ringtail possum (P. herbertensis), but has recently been separated. The two species differ considerably in appearance.
The Daintree River ringtail possum is a cinnamon or brown colour, and has been said, like the lemuroid ringtail possum (Hemibelideus lemuroides), to resemble a lemur. It is found in montane tropical rainforest in three separate populations just north of Cairns: on Carbine Tableland, Mount Windsor Tableland and Thornton Peak massif.[3]

Il coda ad anello cinereo (Pseudochirulus cinereus Tate, 1945) è un marsupiale arboricolo della famiglia degli Pseudocheiridi[2]. È strettamente imparentato con una specie a esso molto simile, il coda ad anello del fiume Herbert (P. herbertensis), tanto che, fino al 1989, le due specie venivano classificate in un unico taxon.
I coda ad anello cinerei, alla nascita, sono ricoperti da un folto manto lanoso di colore marrone chiaro, che rimane inalterato negli esemplari adulti (diversamente da quello dei coda ad anello del fiume Herbert, che negli esemplari adulti diviene molto più scuro). Lungo la testa e il dorso corre una striscia scura. La specie presenta un caratteristico muso appuntito con un «naso romano» e una coda affusolata. Tutte le specie del genere Pseudochirulus hanno la coda prensile. I coda ad anello del fiume Herbert utilizzano questa parte del corpo anche per trasportare piccoli ramoscelli impiegati nella costruzione dei nidi. Dato lo stile di vita prettamente arboricolo, la parte ventrale della coda del coda ad anello cinereo è priva di peli, sì da assicurare una migliore aderenza durante le arrampicate. L'animale possiede inoltre zampe simili a mani che gli consentono di aderire meglio ai rami e ai tronchi.
I maschi tendono a essere più grandi delle femmine: essi pesano 830-1450 g, mentre le femmine pesano 700-1200 g. Misure esatte della lunghezza non sono note, ma specie simili hanno una lunghezza testa-corpo di 16,7-36,8 cm[3].
In base alle abitudini alimentari di specie simili di coda ad anello, è ragionevole pensare che il coda ad anello cinereo sia prevalentemente folivoro. Tutti i coda ad anello, compreso P. cinereus, hanno un grosso cieco contenente batteri in grado di digerire le foglie. Ogni tanto consumano anche fiori o frutti e mostrano comportamenti di coprofagia[3].
I coda ad anello cinerei, come altri possum, hanno abitudini notturne. Dal momento che si nutrono perlopiù di foglie, si spostano molto lentamente, cercando di conservare energie il più possibile, proprio come un loro parente stretto, il coda ad anello del fiume Herbert. Scendono raramente al suolo e trascorrono quasi la loro intera esistenza sugli alberi. Sono perlopiù solitari, ma in rare occasioni più esemplari possono condividere la tana. Durante il giorno possono dedicarsi alla costruzione del nido o riposarsi nelle cavità degli alberi[3].
I coda ad anello cinerei raggiungono la maturità sessuale verso i 18-24 mesi. Possono riprodursi in ogni periodo dell'anno, ma il picco delle nascite viene raggiunto in aprile e maggio. Una volta all'anno la femmina partorisce un'unica nidiata composta in media da due piccoli, che trascorrono i primi 4-5 mesi di vita nel marsupio; successivamente, vengono trasportati sul dorso dalla madre. I piccoli vengono svezzati a 150-160 giorni e raggiungono l'indipendenza a 10 mesi. La speranza di vita stimata è di 4-5 anni in natura e di 15 anni in cattività[3].
La specie occupa un areale compreso tra Cairns e Cape Tribulation, nell'estremità settentrionale del Queensland. Si incontra nelle foreste pluviali al di sopra dei 420 m di quota e ne esistono tre popolazioni separate tra loro, sui monti Carbine, Windsor e Thornton[4].

Pseudochirulus cinereus is een klimbuideldier uit het geslacht Pseudochirulus dat voorkomt in tropisch regenwoud (boven 400 m hoogte) in Noordoost-Queensland ten noorden van Cairns op het Carbine Tableland, het Mount Windsor Tableland en Thornton Peak. Over het gedrag van dit dier is weinig bekend; er zijn jongen in de buidel gevonden tussen juli en december. Deze soort werd eerder tot de zuidelijker voorkomende P. herbertensis gerekend.
De bovenkant is kaneelkleurig tot lichtbruin, de onderkant wit. Over de bovenkant van het lichaam loopt een donkerbruine rugstreep. De staart heeft grotendeels dezelfde kleur als de bovenkant van het lichaam, maar de punt is meestal wit. De kop-romplengte bedraagt 330 tot 370 mm, de staartlengte 320 tot 390 mm en het gewicht 800 tot 1250 g.

Pseudochirulus cinereus[2] är en pungdjursart som beskrevs av Tate 1945. Pseudochirulus cinereus ingår i släktet Pseudochirulus och familjen ringsvanspungråttor.[3][4] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade.[3]
Pungdjuret förekommer i östra delen av Kap Yorkhalvön, Australien. Arten vistas där i olika slags fuktiga skogar.[1]
Arten liknar Herberts pungekorre (Pseudochirulus herbertensis) men är ljusare i pälsfärgen. Ungar av Herberts pungekorre kan ha nästan samma färg. Kännetecknande är en mörk strimma från regionen mellan ögonen över huvudet till främre ryggen på ljusbrun grund. Undersidan är täckt av ljus krämfärgad päls. Svansen är nära bålen mörkare än övre bålen och den har en vit spets. Svansen används som gripverktyg och den är därför naken på nästan hela undersidan.[5]
Djuret vistas i kulliga områden och i bergstrakter mellan 420 och 1200 meter över havet och det föredrar höga regioner. Individerna vilar i trädens håligheter eller ibland på grenar. De äter blad, fikon och kanske andra frukter.[5]
