Conservation Status ( Anglèis )

fornì da Animal Diversity Web

Much of western quoll's habitat has been destroyed through controlled and frequent burns as well as the use of pesticides by surrounding farmers. The introduction of predator species such as foxes, feral cats, and bird of preys by European settlers has also reduced their numbers. The new predators compete with western quoll for food and also prey upon them. There have been successful attempts to breed D. geoffroii in captivity and release them (Perth Zoo). Research on western quoll and their habitat have been conducted in hopes of finding a way to preserve the species in the wild. Various areas have passed acts in an attempt to conserve these marsupials but there are no statistics on their success. (Mawson 1996, Massicot 2000, Murdoch University 1997)

Trophic Strategy ( Anglèis )

fornì da Animal Diversity Web

Their diet is rather diverse, ranging from large insects, to small vertebrates, to carrion. In arid habitats they have been found to eat mammals the size of rabbits, lizards, frogs, and invertebrates. In forested habitats they consume insects, freshwater crustaceans, reptiles, parrot-sized birds, and rabbit-sized mammals. In human-settled areas they will raid chicken coops and rubbish bins. Dasyurus geoffroii kills larger prey by biting the back of the head or neck. This carnivore is primarily a ground forager and nocturnal though it does occasionally climb trees.

The original habitat of western quolls was once quite large, including stretches of desert in the arid part of Central Australia. However due to various causes, D. geoffroii's territory has been reduced to the Jarrah forests in the southwest portion of South Australia. These areas consist of open forest, low open forest, woodland, and open shrub.

Reproduction ( Anglèis )

fornì da Animal Diversity Web

Western quolls are seasonal breeders, mating between the months of May and July with a peak in June. Nnormal litter size ranges from 2 to 6 young per year, there have been cases where females produce more young than can be nurses. After a gestational period of 16 to 23 days, western quolls remain in their mother's shallow pouch for another seven to fifteen weeks until they outgrow the pouch. At this point they are left in the den while the female forages for food. Dasyurus geoffroii are independent at 18 weeks and weaned at 23 to 24 weeks, both the male and female are sexually mature at one year of age.

Biology ( Anglèis )

fornì da Arkive
The chuditch is a solitary and nocturnal marsupial with a territorial attitude towards its home range, particularly the central core area of the range which is marked by many dens. Males and females do not meet outside of the May to July breeding season, although males territories, at about 15 km², overlap with several female ranges, at about three to four square kilometres each, and may also overlap with the peripheries of other male territories. Female home ranges do not overlap. A typical female territory might contain around 70 hollow log dens and 110 burrows. The chuditch sleeps in hollow logs, stone piles, and burrows dug both by themselves and left by other animals (3). Pregnant females will give birth to between two and six young per year after a gestation period of 17 to 18 days. The young marsupials move directly into the shallow pouch of their mother where they remain for a further eight to nine weeks (5). Following this period, they remain with their mother but are often left in the large burrow she constructed before giving birth, while she forages for herself and for her offspring. The young are independent at 18 weeks, leaving their mother's home range to find their own. At one year they are sexually mature and most will breed (3). The chuditch is essentially opportunistic, although fruit is not a common part of the diet. Small to medium sized mammals, lizards, frogs and large invertebrates are common prey in arid habitats, and insects, freshwater crustaceans, reptiles, birds and mammals are common prey in forest habitats. Carrion is also consumed, as are small fruits and flower-parts and the red pulp surrounding Zamia seeds (2) (4). The chuditch obtains all the liquid it requires from its diet, so rarely drinks and is able to remain active in temperatures as low as zero degrees Celsius (4).

Conservation ( Anglèis )

fornì da Arkive
A recovery plan for the chuditch was prepared in 1994 and various conservation actions have been undertaken to attempt to increase chuditch numbers. Captive breeding programmes have been successful, and research into the chuditch and its habitat is ongoing (3). Introduced predator control, particularly of red foxes, has reduced predator numbers, and the maintenance of refuge sites in the Jarrah Forest where populations still exist should improve population counts. Populations are being monitored, and translocations to five sites in the southwest of Western Australia have improved chuditch numbers in this area. A re-assessment of the conservation status of the chuditch is currently underway.

Threats ( Anglèis )

The range of the chuditch has been reduced to just two percent of the size of its original range, due to habitat loss and degradation, as well as from increased predation and competition for food from introduced species such as foxes, feral cats, dingoes and birds of prey (3). The majority of habitat lost has been a result of clearing for farming, forestry and increasingly frequent controlled and wild fires (1). When it was more common, the chuditch was known to raid chicken coops and rubbish bins in settled areas, and consequently was seen as a pest and trapped or poisoned (1) (5).

Verbreitung des Schwarzschwanz-Beutelmarders

Der Schwarzschwanz-Beutelmarder oder Westliche Beutelmarder (Dasyurus geoffroii) ist eine Art aus der Familie der Raubbeutler.

Merkmale

Er erreicht eine Kopfrumpflänge von 26 bis 40 cm und ein Gewicht von 615 bis 2185 g. Die Männchen sind in der Regel etwas größer und schwerer als die Weibchen. Die Oberseite ist braun mit den für die Gattung typischen großen weißen Flecken, die Unterseite ist cremefarben. Die hintere Hälfte des buschigen Schwanzes ist schwarz gefärbt, bei manchen Individuen mit ein bis zwei weißen Flecken an der Basis. Die Hinterfüße sind fünfstrahlig.

Verbreitung

Ursprünglich war der Schwarzschwanz-Beutelmarder von der Westküste Australiens über das gesamte Innere des Kontinents verbreitet. Nach der Besiedlung des Kontinents durch die Europäer schrumpfte das Verbreitungsgebiet stark zusammen, seit den 1950er Jahren kommt die Art nur noch im äußersten Südwesten des Landes vor.

Lebensraum

Ursprünglich auch in Wüstengebieten verbreitet, leben die heutigen Populationen in trockenen Wald- und Buschländern.

Lebensweise

Der westliche Beutelmarder ist hauptsächlich bodenlebend und erklettert nur ausnahmsweise Bäume zur Nahrungssuche oder um Fressfeinden zu entkommen. Obwohl die Art vor allem nachtaktiv ist, wird bei schlechten Witterungsbedingungen auch tagsüber nach Beute gejagt. Die Nahrung setzt sich aus kleinen Säugern, Vögeln, Reptilien und Insekten zusammen. Die Streifgebiete sind vergleichsweise groß, sie können bei Männchen mehr als 400 Hektar betragen.

Western quoll ( Anglèis )

fornì da wikipedia EN

The western quoll (Dasyurus geoffroii) is Western Australia's largest endemic mammalian carnivore.[4] One of the many marsupial mammals native to Australia, it is also known as the chuditch. The species is currently classed as near-threatened.

Taxonomy

The western quoll is a member of the family Dasyuridae and is most closely related to the bronze quoll (Dasyurus spartacus), a recently described species from New Guinea that was for some time believed to be an outlying population of the western quoll. Its species name, geoffroii, refers to the prominent French naturalist Étienne Geoffroy Saint-Hilaire, who named the genus Dasyurus in 1796. The species has occasionally been placed in the genus Dasyurinus.[5]

It is also known as the chuditch (/ˈʊdɪ/) in Western Australia (from Noongar djooditj);[6] chuditch serves as both the singular and plural form. Other common names include atyelpe or chilpa (from Arrernte),[7] kuninka (from Western Desert language);[8] idnya (Adnyamathanha people of the Flinders Ranges)[9] and the archaic western native cat.

Description

The western quoll is about the size of a domestic cat. It is coloured a rufous brown and has 40–70 white spots on its back with a creamy white underside. Its spots help diminish its outline under moonlight at night when hunting.[10] It has five toes on its hind feet and granular pads.[5] The head and body are about 36 cm to 46 cm in length, and the tail is around 22 cm to 30 cm.[11] With large eyes and pointed ears,[11] it is well adapted for nocturnal life. The black brush on its tail extends from halfway down to the tip. Males typically weigh around 1.3 kg, and females 0.9 kg. The longest they are likely to live is four years.[4]

Often confused with eastern quoll, it differs in possessing a first toe on the hind foot and a darker tail. It does share a white-spotted brown coat and a long tail with both the eastern quoll and northern quoll.

Habitat

Once found across 70% of the Australian continent, the western quoll is now confined to south-western corner of Western Australia. This perhaps was due to European settlement in the late 1780s as their range dramatically declined after this event.[4] It currently inhabits wet and dry sclerophyll forests, including contiguous Jarrah Forest and mallee.[12] These areas consist of open forest, low open forest, woodland, and open shrub.[11] On occasion they are recorded in the WA Wheatbelt and Goldfields regions, and by the 1930s disappeared completely from Swan Coastal Plain and surrounds.[4]

As a result of its carnivorous feeding habits, the western quoll has a large home range. These territories often share rock ledges and other open spaces. This serves to mark territory and for other social functions. Males spread out over about 15 square kilometres and typically overlap with several female ranges, about three to four square kilometres each. Although males share their large territories with smaller female territories, females do not cross theirs with other females. Most female home ranges contains around 70 hollow log dens and 110 burrows.[13]

Behaviour

A solitary, mostly terrestrial nocturnal predator, the western quoll is most active around dusk (crepuscular) when it hunts. It moves swiftly on the ground, climbs efficiently, and may dig or occupy existing burrows. During the day it seeks refuge in hollow logs or earth burrows as dens,[14] and saves energy by lowering its body temperature in its sleep.[15]

The western quoll is at the top of the food chain, and depends on resource abundance and a healthy ecosystem.[14] Being a carnivore, the western quoll feeds on large invertebrates and any small animal it can. This includes lizards, birds, frogs, spiders, insects, and small mammals; the largest it will eat is the size of a bandicoot or parrot.

Reintroduced populations in South Australia have been recorded preying on rabbits[16] and burrowing bettongs.[17]

They hunt mostly on the ground, but will climb a tree to grab a bird's egg. A bite to the back of the head kills their larger prey. It possesses an ability to obtain most of its water from its food, which is especially handy for survival during a drought.[14]

As seasonal breeders, western quolls mate between late April to July, and have a peak in June.[12] During this time, the western quoll tends to take up large areas of habitat, and females aggressively defend their territory of 55-120 ha.[15] Male and female quolls meet up only to mate. Although there are occasional cases when more young are produced than can be nursed, most litters range from two to six. There is a gestational period of 16 to 23 days which is followed by the young living in their mother's shallow pouch. After another seven to fifteen weeks, the young outgrow the pouch and are left in the den while the female forages for food. Weaned at 23 to 24 weeks, western quoll are independent at 18 weeks and are sexually mature at one year of age. The young disperse in November before taking up their own territories.[11]

Decline

The western quoll has declined due to several factors. Land clearing, inappropriate fire regimes, grazing by stock and feral herbivores, illegal shooting, accidental drowning in water tanks, being hit by motor vehicles, and poisoning are all responsible for their disappearances. Foxes and cats have a massive impact; both predation and competition narrow room for the western quoll.[4] As more land became less suitable for living in, the western quoll is forced to move elsewhere.

AWC (Australia Wildlife Conservancy) protects this species at Paruna Sanctuary using a comprehensive feral predator control program, which sees feral cat and fox numbers controlled using trapping and baiting.[4]

Reintroductions

There have been ongoing attempts to re-establish the western quoll in parts of its former range.[18]

A five-year trial re-introduction of western quoll to the Flinders Ranges in South Australia began in April 2014.[9] Despite the loss of about a third of the first release population (mostly due to predation by feral cats), most of the surviving females bred and sixty joeys were born.[19] As of May 2016, a final release of 15 quolls from Western Australia was carried out in the Flinders Ranges, with a total population of 150. About half of this population was born locally. Monitoring of the population continued for an additional two years.[20] The success of the reintroduction led to relocation of animals from the initial site in the Ikara-Flinders Ranges National Park to the Vulkathunha-Gammon Ranges National Park in 2022 and 2023.[21][22]

The species has been returned to the South Australian arid zone, with a population established at the fenced Arid Recovery Reserve near Roxby Downs.[23] Animals were reintroduced to the semi-arid Mount Gibson Sanctuary in WA in April 2023, with the aid of feral predator control.[24]

Plans are in process to reintroduce the species to Dirk Hartog Island in Shark Bay,[25] Wardang Island[26] as part of the Marna Banggara[27] (formerly Great Southern Ark) project on the southern Yorke Peninsula[28] in South Australia, and large fenced reserves in the Pilliga Forest,[29] Mallee Cliffs National Park[30] and Sturt National Park,[31] all in NSW.

Captive breeding programs have contributed to reintroduction efforts, with Perth Zoo providing some animals for release.[11]

Dasyurus geoffroii ( Spagneul; Castilian )

fornì da wikipedia ES

El cuol occidental (Dasyurus geoffroii), también conocido como chudchit o gato nativo occidental es una especie de marsupial dasiuromorfo de la familia Dasyuridae. Está más relacionado con el cuol de bronce (D. spartacus) que con cualquier otra especie del género, hasta el punto de que la especie neoguineana fue considerada antaño como una subespecie de la australiana.

Zoogeografía

Habita los bosques de Jarrah (bosque abierto y matorral) en el extremo suroccidental de Australia, aunque en otro tiempo alcanzó la práctica totalidad de la mitad meridional de la misma.[1]

Faneróptica y anatomía

Es una especie de tamaño medio dentro del género, aunque el marcado dimorfismo sexual hace que las hembras sean de las más pequeñas dentro del mismo. Pesa entre 900 y 1300 g y mide de 36 a 46 cm de longitud, más una cola de 22 a 30 cm.[1]

La diferencia principal de esta especie con respecto al resto de sus congéneres es que la cara es más pálida que el resto del cuerpo.

Dieta

La dieta es muy variada. Aunque presenta modificaciones cuantitativas y cualitativas en función de los recursos del medio, en ella se incluyen mamíferos que en ocasiones pueden superar en tamaño al individuo, reptiles, aves, anfibios, insectos, crustáceos acuáticos y otros invertebrados.

Reproducción

La época de celo va de mayo a julio; el periodo de gestación es de 16 a 23 días. Aunque puede alumbrar más crías, la única camada anual suele ser de entre dos y seis individuos. La lactancia dura hasta las 23 o 24 semanas. Los recién nacidos permanecen entre 7-15 semanas en el marsupio, para ser posteriormente dejados en una madriguera donde la madre vuelve a amamantarlos. A partir de la 18ª semana los cachorros adquieren mayor independencia. La madurez se alcanza al año de edad. La esperanza de vida es de 3 o 4 años en libertad y hasta 5 años y medio en cautividad.[1]

Comportamiento

Son animales nocturnos y solitarios. Fundamentalmente terrestres aunque pueden trepar ágilmente a los árboles. Son territoriales, y aunque el área de un macho puede solaparse con las de varias hembras, solamente mantendrán algún tipo de relación en la época de cría.[1]

Estado de conservación

Clasificación UICN: Casi amenazado.[2]​ Este animal es empleado como alimento por algunas tribus aborígenes, siendo considerado además como un animal mítico.

Chat marsupial de Geoffroy ( Fransèis )

fornì da wikipedia FR

Dasyurus geoffroii

Le chat marsupial de Geoffroy (Dasyurus geoffroii), est un dasyuromorphe australien vulnérable, dont la distribution est désormais confinée au sud-ouest de l'Australie-Occidentale.

Description

Le chat marsupial de Geoffroy est un chat marsupial de taille moyenne dont le pelage est brun roux sur le dessus et blanc crème sur le ventre. Il possède cinq doigts sur ses pattes de derrière et des coussinets granuleux[1].

Le chat marsupial de Geoffroy est un prédateur solitaire et nocturne, plutôt terrestre, bien qu'il sache grimper aux arbres. Il se nourrit de petits vertébrés, de charognes, d'arthropodes et d'écrevisses d'eau douce, entre autres. La saison de reproduction a lieu en avril-juillet[2].

Habitat

Le chat marsupial de Geoffroy était autrefois présent dans presque toute l'Australie intérieure, s'étendant dans les régions du Queensland, de Nouvelle-Galles du Sud et de Victoria. Il est désormais restreint au coin sud-ouest de l'Australie-Occidentale, où il habite les forêts sclérophiles humides et sèches et le mallee[2].

Classification

Le chat marsupial de Geoffroy a été décrit par John Gould en 1841, quand il était encore répandu sur tout le continent. Son nom d'espèce, geoffroii, se réfère au fameux naturaliste français Étienne Geoffroy Saint-Hilaire, qui nomma le genre Dasyurus en 1796. L'espèce est parfois placée dans le genre Dasyurinus[1].

Le Chat marsupial de Geoffroy est un membre de la famille des Dasyuridae est fortement apparenté au chat marsupial bronzé (Dasyurus spartacus), une espèce de Nouvelle-Guinée récemment décrite que l'on prit un temps pour une population éloignée du chat marsupial de Geoffroy.

Deux sous-espèces de chat marsupial de Geoffroy sont connues[1] :

  • D. g. geoffroii, présent en Australie intérieure (désormais éteint)
  • D. g. fortis, présent dans le sud-ouest de l'Australie-Occidentale

Dasyurus geoffroii ( Italian )

fornì da wikipedia IT

Il quoll occidentale (Dasyurus geoffroii Gould, 1841), noto anche come gatto marsupiale di Geoffroy o chuditch (dal termine aborigeno djooditj), è un mammifero dasiuromorfo australiano[2].

Descrizione

Il quoll occidentale ha pressappoco le dimensioni di un gatto: i maschi hanno una lunghezza testa-corpo di 31-40 cm e una coda di 25-35 cm, le femmine una lunghezza testa-corpo di 26-36 cm e una coda di 21-31 cm; i primi pesano 0,7-2 kg, le seconde 0,6-1,1 kg. Ha un mantello morbido, di colore marrone, segnato, su dorso e zampe, da una serie di macchie bianche. La coda è ricoperta da lunghi peli neri. La faccia è appuntita e ha una colorazione più chiara del resto del corpo; gli occhi sono piuttosto grandi e le orecchie, ricoperte di peli bianchi, rotondeggianti[3].

Biologia

Comportamento

È un marsupiale solitario e notturno, strettamente territoriale; le zone centrali degli home range sono delimitate da cumuli di escrementi. Maschi e femmine si incontrano unicamente nella stagione degli amori (tra maggio e luglio), sebbene i territori dei primi, estesi per circa 15 km², si sovrappongano a quelli di più femmine, ciascuno di 3-4 km², o addirittura alle zone periferiche dei territori di altri maschi. Quelli delle femmine, invece, non si sovrappongono mai. Ciascun territorio di una femmina può comprendere circa 70 tronchi-ricovero e 110 gallerie. I quell trovano riparo in tronchi caduti, cumuli di pietre e tane, scavate da essi stessi o abbandonate da altri animali[3].

Alimentazione

Il quoll occidentale è un animale molto opportunista, e la sua dieta varia a seconda dell'habitat: nelle zone aride, infatti, essa è costituita essenzialmente da mammiferi di piccole o medie dimensioni, lucertole, rane e grossi invertebrati, mentre nelle zone umide comprende insetti, crostacei d'acqua dolce, rettili, uccelli e mammiferi. Divora anche carogne, così come piccoli frutti, parti di fiori e la polpa rossa che circonda i semi di Zamia. Il quoll ricava i liquidi necessari dagli alimenti e quindi beve solo raramente[3].

Riproduzione

Le femmine, dopo una gestazione di 17-18 giorni, partoriscono da due a sei piccoli, che si dirigono rapidamente nel marsupio materno, dove rimarranno per otto-nove settimane. In seguito, essi rimangono con la madre ma vengono spesso lasciati nella grande tana da essa costruita prima del parto. Raggiungono l'indipendenza a 18 settimane di età, ma diverranno sessualmente maturi solo all'età di un anno[3].

Distribuzione e habitat

In passato il quoll occidentale era diffuso in gran parte del continente australiano, compresi Queensland, Nuovo Galles del Sud e Victoria. Attualmente, è presente unicamente nell'angolo sud-occidentale dell'Australia Occidentale, dove si incontra in foreste umide e secche di sclerofille umide e aride, e nel mallee[4].

Tassonomia

Il quoll occidentale è stato descritto per la prima volta da John Gould nel 1841, quando era ancora diffuso in gran parte del continente. Il suo nome specifico, geoffroii, commemora il grande naturalista francese Étienne Geoffroy Saint-Hilaire, che istituì il genere Dasyurus nel 1796. Questa specie è stata talvolta classificata in un genere a parte, Dasyurinus[5].

Appartiene alla famiglia dei Dasiuridi ed è strettamente imparentato con il quoll bronzeo (Dasyurus spartacus), una specie descritta solo di recente diffusa in Nuova Guinea e ritenuta talvolta una popolazione periferica di quoll occidentale.

Zwartstaartbuidelmarter ( olandèis; flamand )

fornì da wikipedia NL

De zwartstaartbuidelmarter (Dasyurus geoffroii), ook wel westelijke buidelmarter of chuditch genoemd, is een roofbuideldier uit het geslacht der buidelmarters (Dasyurus).

Uiterlijk

De zwartstaartbuidelmarter heeft een lichaamslengte van 25 tot 40 cm en een staartlengte van 20 tot 35 cm. Het gewicht varieert van 600 gram tot 2.0 kg. Net als de overige buidelmarters heeft deze soort een bruine vacht met kleine of grotere witte vlekken. De buikzijde is lichter van kleur.

Leefwijze

De zwartstaartbuidelmarter leeft voornamelijk op de grond, hoewel het een uitstekende klimmer is. Over het algemeen is dit buidelroofdier 's nachts actief en slaapt het overdag in een hol. Dit hol kan uitgegraven worden in de grond of bestaan uit holtes in bomen of rotsen. De zwartstaartbuidelmarter voedt zich voornamelijk met insecten en kleine gewervelde dieren als kikkers, hagedissen, kleine vogels en knaagdieren als de Australische springmuis (Notomys alexis). Daarnaast worden ook aas, vruchten en (in door mensen bewoonde gebieden) afval gegeten. De zwartstaartbuidelmarter is goed aangepast aan eventuele droge omstandigheden, aangezien het lichaam van dit dier slechts weinig water verliest. Dit heeft bovendien als gevolg dat de zwartstaartbuidelmarter slechts weinig hoeft te drinken en veel van het benodigde water reeds binnenkrijgt via zijn prooien.

Leefgebied

De zwartstaartbuidelmarter bewoonde vroeger ongeveer 70% van Australië en was aanwezig verschillende leefgebieden variërend van woestijn tot bosgebied in alle staten en territoria op het vasteland. Verlies van habitat en competitie van ingevoerde vossen en verwilderde katten hebben ertoe geleid dat dit buideldier tegenwoordig alleen nog leeft in het zuidwesten van de staat West-Australië. De zwartstaartbuidelmarter is nog te vinden in de eucalyptusbossen van Jarrah Forest en de boomsavannes en mallee scrublands van de Wheatbelt Region en de omgeving van Hopetoun.

In gevangenschap

In gevangenschap is de zwartstaartbuidelmarter alleen in Perth Zoo, Caversham Wildlife Park en Alice Springs Desert Park te zien.

Dasyurus geoffroii ( portughèis )

fornì da wikipedia PT

O quoll ocidental (Dasyurus geoffroii) é uma espécie de marsupial da família Dasyuridae.

Endêmica da Austrália.

Características

O quoll ocidental é de tamanho médio, de coloração marrom-avermelhado no dorso e com manchas brancas, o ventre é branco-creme. Tem cinco dedos e almofadas granular em suas patas traseiras. Medem cerca de 33 cm de comprimento e a cauda 28 cm, podem pesar até 2 kg sendo os machos ligeiramente mais pesados que as fêmeas.

O quoll ocidental foi descrito por John Gould em 1841, quando era ainda muito difundido em todo continente. O nome da espécie, geoffroii, refere-se ao proeminente naturalista francês E. Geoffroy, que nomeou o gênero Dasyurus em 1796. A espécie tem sido por vezes colocada no gênero Dasyurinus; O quoll ocidental é mais estreitamente relacionado com o quoll bronzeado (Dasyurus spartacus), uma espécie recentemente descrita de Nova Guiné, que foi durante algum tempo acreditada ser uma população periférica do quoll ocidental;

Hábitos alimentares

São predadores solitários, principalmente noturnos e terrestres, alimentam-se de pequenos vertebrados, carniça, artrópodes e lagostins de água doce, entre outras coisas.

Habitat

O quoll ocidental já foi encontrado durante a maior parte das regiões da Austrália, atingindo áreas de Queensland, Nova Gales do Sul e Victória. Agora é restrito a região sudoeste da Austrália Ocidental, onde hábita florestas úmidas e secas de sclerofilas.

Distribuição Geográfica

Sudoeste da Austrália Ocidental, antigamente na Austrália Meridional, Território do Norte, Sul de Queensland, Oeste de Nova Gales do Sul e Noroeste de Victoria;

Subespécies

  • Subespécie: Dasyrurus geoffroii fortis? (Thomas, 1906)

Dasyurus geoffroii ( svedèis )

fornì da wikipedia SV


Dasyurus geoffroii[2][3][4][5] är en pungdjursart som beskrevs av John Gould 1841. Dasyurus geoffroii ingår i släktet pungmårdar och familjen rovpungdjur.[6][7] Inga underarter finns listade.[6]

Utseende

Arten når en kroppslängd (huvud och bål) av 26 till 40 cm, en svanslängd av 21 till 35 cm och en vikt av 0,6 till 2,1 kg. Den har huvudsakligen brun päls med flera vita fläckar. Vid slutet av djurets bruna yviga svans är flera svarta hår inblandade. Ibland förekommer ljusare fläckar på svansen. Huvudet kännetecknas av en spetsig nos, stora ögon och avrundade öron som är täckta av korta vita hår.[8]

Utbredning och ekologi

Pungdjuret hade ursprungligen ett stort utbredningsområde i Australien men förekommer numera endast i kontinentens sydvästra hörn. Arten kan leva i olika habitat som skogar, buskland och öken. Individerna är främst aktiva på natten och lever utanför parningstiden ensam. Födan utgörs främst av ryggradslösa djur.[1]

Dasyurus geoffroii kan under parningstiden och under regniga dagar vara dagaktiv. Boet som fodras med gräs och löv är en hålighet i ett träd som ligger på marken, en bergsspricka, en ihålig tom termitstack eller ett näste som skapades av ett annat djur. Hannarnas revir är cirka 400 hektar stort och honor har vanligen ett 100 hektar stort territorium. Allmänt har en individ flera bon i reviret. Individerna går främst på marken men de kan klättra i växtligheten. Förutom ryggradslösa djur äts grodor, ödlor, småfåglar, mindre däggdjur och frukter.[8]

Fortplantningstiden sträcker sig från maj till september och de flesta ungar föds i juni eller juli. Dräktigheten varar bara 17 eller 18 dagar och sedan föds 2 till 6 ungar. De är underutvecklade och kravlar fram till en spene i moderns pung (marsupium). Efter 8 till 9 veckor syns de för första gången utanför pungen och efter cirka 16 veckor är pälsen full utvecklad. Ungarna diar sin mor upp till 24 veckor och de blir efter ungefär ett år könsmogna. Dasyurus geoffroii lever vanligen tre år i naturen. Några exemplar i fångenskap blev fem år gamla.[8]

Status

Arten hotas främst av habitatförstöring. Flera individer dog i samband med bränder. Dasyurus geoffroii konkurrerar med de introducerade tamkatter och rödrävar om samma föda. IUCN kategoriserar arten globalt som nära hotad.[1]

Чернохвостая сумчатая куница[1], или сумчатая куница Жоффруа[2] (лат. Dasyurus geoffroii) — вид из рода полосатых сумчатых куниц семейства хищные сумчатые. Видовое название дано в честь французского зоолога Этьена Жоффруа Сент-Илера (1772—1844)[3]. Эндемик Австралии.

Распространение

Чернохвостая сумчатая куница, в прошлом представленная двумя подвидами, населяла 70 % австралийской территории, встречаясь в каждом из австралийских континентальных штатов и в Северной территории. Вымерший подвид лат. D. g. geoffroii известен по найденным экземплярам из района города Пик-Даунс в восточной части Квинсленда, равнины Ливерпул в Новом Южном Уэльсе и города Милдьюра в Новом Южном Уэльсе. Западный подвид, лат. D. g. fortis, в настоящее время ограничен юго-западной частью австралийского штата Западная Австралия[4].

Естественная среда обитания — пустыни, луга, местности, покрытые кустарником, склерофитовые леса, прибрежные районы[4][5].

Внешний вид

Между самцами и самками существует половой диморфизм. Вес взрослого самца колеблется от 0,7 до 2 кг, самки — от 0,6 до 1,12 кг. Длина тела с головой у самца варьирует от 310 до 400 мм, у самки — от 260 до 360 мм. Длина хвоста у самца — от 250 до 350 мм, у самки — от 210 до 310 мм[6]. Волосяной покров мягкий. Спина и бока коричневого или чёрного цвета, с многочисленными белыми пятнами неправильной формы. Брюхо — кремово-белое. Морда вытянутая, заострённая, покрыта более бледным волосяным покровом. Уши крупные, округлые, с белыми ободками. Глаза большие. Уши округлые. Лапы укороченные[5] В отличие от крапчатой сумчатой куницы имеет первый палец на задней конечности, а также зернистые подошвенные подушечки[7].

Образ жизни

Ведут наземный образ жизни, хотя с лёгкостью могут лазить по деревьям. Живут в норах, иногда в гнёздах других животных (или даже птиц) или в дуплах деревьев[6]. Самки самостоятельно выкапывают норы, чтобы дать потомство. Главный туннель норы ведет в часть, предназначенную для детёнышей и залегающую на глубине почти 1 м[8]. Активность приходится на ночь, день проводится в своих норах[7]. Ведут одиночный образ жизни. Самки с самками встречаются только в период размножения[5]. Рацион разнообразен, включает в себя насекомых, мелких позвоночных, растения. В засушливых районах питаются мелкими позвоночными, размеры которых сопоставимы с кроликами, а также ящерицами, лягушками и беспозвоночными[5].

Размножение

Выводковая сумка развивается только в период размножения, открывается назад. Период размножения длится с мая по июль. Пик приходится на июнь. Беременность короткая, длится в среднем 16 дней. В год на свет появляется от 2 до 6 детёнышей (иногда рождается больше детёнышей, чем количество сосков у матери)[5]. Молодняк отлучается от груди примерно через 158 дней. Вес при рождении — всего 0,011 г[9]. Половая зрелость наступает примерно через 365 дней. Максимальная продолжительность жизни в неволе — 6,2 лет. В естественной среде обитания продолжительность жизни колеблется от 2 до 5 лет[9].
