Outside of the breeding season, the Shark Bay mouse does not seem to use burrows as much as other Pseudomys species, but rather builds tunnels and runways amongst vegetation, which it uses as daytime refuges. The mice on Doole Island have been observed using hollows in mangrove trees, as well as sites among rocks for daytime refuges. Little is known about the diet of this nocturnal species, although it is believed to comprise flowers, leaves and insects, and individuals have been recorded eating spiders (3). The Shark Bay mouse is apparently solitary (2), and most information on its reproductive behaviour has come from observations of captive animals (3). Breeding on Bernier Island primarily takes place between May and November and gestation lasts around 28 days (2) (3). Litters of up to five young have been recorded in captivity, although around three is thought to be more common (2) (3). Young are born hairless but are furred by 11 days, although the eyes remain closed for a further four (2) (3). Young are weaned by four weeks and obtain full adult size at around 100 days. Specimens on Bernier Island have lived for at least two years (3).

Conservation ( Inglês )

Thankfully, the Shark Bay mouse population on Bernier Island is protected from the threats that have impacted those on the mainland, as this island is part of the Bernier and Dorre Islands Nature Reserve and lacks any exotic predators. Feral goats were eradicated in 1984, and public access is limited to day visits. Nevertheless, this restricted distribution left the species in a highly vulnerable position. Thus, a Recovery Plan was created for the mouse, which involved the translocation of populations to three other exotic predator-free island nature reserves, Doole Island (June 1993), North West Island (June 1999), and Faure Island (June 2003), and to Heirisson Prong, Shark Bay, on the mainland (November 1994), after intensive feral animal control had been undertaken (3) (5). The reintroduced populations have been monitored on an ongoing basis and restocking has occurred where necessary (3). However, the populations on Doole Island and Heirisson Prong have not persisted. It is believed that predation by Varanus lizards prevented the establishment of a viable population at these sites (5). To aid the translocation programs, a captive breeding programme was established in 1998 at Perth Zoo. It is vital that translocated populations become established and self-sustaining if this geographically restricted mouse is to be brought out of the danger zone, but so far these have had mixed success, and the future of this tiny mammal remains uncertain (3).

Description ( Inglês )

fornecido por Arkive
The Shark Bay mouse is a robust, long-haired rodent often given the nickname 'shaggy mouse' for the shaggy fur that covers its body (2) (3). The fur is pale yellow-fawn mixed with grey on the back, giving a grizzled appearance, fading into buff on the sides and white below (2) (3). The tail is slightly longer than the head and body and is coloured grey on top and white underneath, with a dark tuft of hairs at the tip (2) (3).

Threats ( Inglês )

fornecido por Arkive
Before translocations to other locations began in 1993, the Shark Bay mouse was amongst the most threatened of all Australia's mammals, being geographically restricted to just one small island, after having become extinct on the mainland. The precise reasons for the decline of this species are unknown, although a number of theories exist. One suggestion is that cats introduced to the mainland by 19th century may have been responsible for the decline and extinction of many native species on the mainland, but particularly rodents. Predation by foxes may also have had an impact. Another idea is that grazing and trampling by domestic stock brought over by European settlers has contributed to the extinction of Australian fauna on the mainland, possibly including the Shark bay mouse. Likewise, it has been proposed that the rabbit has degraded and competed for fertile habitat, a particularly scarce resource in arid zones of Australia, especially in those that experience successive periods of drought. Altered fire regimes have also been cited as a possible reason for the decline of native species. Sadly, the fact that the Shark Bay mouse does not construct substantial burrow systems underground, but rather build tunnels in vegetation, means that it is particularly exposed and vulnerable to these threats, more so than many other rodents (3).

Djoongari ( Inglês )

fornecido por wikipedia EN

Gould's mouse (Pseudomys gouldii), also known as the Shark Bay mouse and djoongari in the Pintupi and Luritja languages, is a species of rodent in the murid family. Once ranging throughout Australia from Western Australia to New South Wales, its range has since been reduced to five islands off the coast of Western Australia.[3][4]

Taxonomy

In 2021, a comprehensive genetic analysis of native Australian rodents found the djoongari or Shark Bay mouse (P. fieldi), which survives on several islands off the coast of Western Australia, to be conspecific with the Gould's mouse. This would make the Gould's mouse, formerly thought extinct, extant once again, albeit only surviving on several islands, a fraction of its former range.[5][6][7] The study is based on earlier work by Emily Roycroft for a PhD thesis.[8] It has been proposed that the P. gouldii be retained for the merged species as P. gouldii was described first, but the species' common name be changed to djoongari or Shark Bay mouse.[9]

Description

A large species of Pseudomys, an Australian genus of rodents, with long and shaggy fur. The coloration of the upper parts of djoongari is a pale yellowish fawn interspersed with darker brown guard hairs. The size of the head and body combined ranges from 90 to 115 millimetres (3.5 to 4.5 in), the tail is a slightly greater length of 115 to 125 millimetres (4.5 to 4.9 in). Djoongari have an average mass of 45 grams (1.6 oz), and may range from 30 to 50 grams (1.1 to 1.8 oz). The greyish ears are 19 millimetres (0.75 in) from the notch to tip. The underside of the pelage is whitish, becoming a buff colour as it grades into the upper parts, the feet are also whitish. The hind foot is 26 to 27 millimetres (1.0 to 1.1 in) long. The upper surface of the tail is greyish, and distinctly contrasts the lighter coloured lower surface. The tail ends with a tuft of dark fur. Pseudomys gouldii possess two pairs of inguinal teats.

Discovery

As Pseudomys fieldii, the species was described in a description published by Edgar Ravenswood Waite in 1896, the holotype was obtained at Alice Springs; the author allied the new species to the genus Mus. Another description was provided in 1910 by the mammalogist Oldfield Thomas, a new species named as Pseudomys (Thetomys) praeconis. Thomas described a specimen that was obtained at Shark Bay, where the collector Guy C. Shortridge found the dry skull of a female lying on the ground on Bernier Island at the Peron Peninsula; Shortridge reported that he thought the species was locally extinct. Another specimen held at the British Museum, an old female obtained by F. M. Rayner during the voyage of HMS Herald in 1858, was designated as the holotype. The specific epithet was nominated by Waite to fulfil a request of Walter Baldwin Spencer that J. Field be acknowledged for their collection of specimens during the Horn expedition.

Range

It was once found throughout the entire Australian continent, from Western Australia eastwards to New South Wales. but suffered greatly after the arrival of Europeans and feral animals, and eventually its range became reduced to coastal sand dunes on Bernier Island, leaving it severely endangered.

In 2003 the Australian Wildlife Conservancy (AWC) released some Shark Bay mice onto Faure Island in the hope of creating another population. Despite the presence of owls the reintroduction was successful and the population quickly grew to a larger size than that of Bernier Island, no longer leaving the species on the brink of extinction.

The species was reintroduced to Dirk Hartog Island in April 2021, with specimens gathered from another reintroduced population on Western Australia's North West Island.[4][10]

Fossil evidence expanded the known range of Pseudomys praeconis from the Shark Bay area to areas along the western coast of Australia (Archer and Baynes 1973 and Baynes 1982 cited in Baynes 1990, p. 317), and further inland into the arid zones (Baynes 1984 cited in Baynes 1990, p. 318). It was realised, as the range was further extended by fossil remains, the remains of Pseudomys fieldi represented the easterly bound of the one species (Baynes 1990, 318).

Behavior

It is slightly smaller than a black rat, and quite social, living in small family groups of 4–8 that sheltered by day in a nest of soft, dry grass in a burrow. It usually digs burrows at a depth of 15 centimetres (5.9 in) under bushes.[9][11]

Status

Gould's mouse was common and widespread before European settlement, but disappeared rapidly after the 1840s, perhaps being exterminated by feral cats. Alternatively, it may have been out-competed by the introduced rats and mice, succumbed to introduced diseases or been affected by grazing stock and changed fire regimes. Despite extensive survey work in its known range, the last specimens were collected in 1856–57, and it was declared officially extinct in 1990 by the IUCN, having been last collected in 1856–1857 by John Gilbert for John Gould, and not sighted since despite several surveys of the area.[11] However, a 2021 genetic study found that it survived on small islands off the coast of Western Australia, in populations which were formerly thought to be their own species known as djoongari. The djoongari is presently classified as Vulnerable on the IUCN Red List.[5][6]

Alice Springs-muis ( Neerlandês; Flamengo )

fornecido por wikipedia NL

De Alice Springs-muis (Pseudomys fieldi) is een knaagdier uit het geslacht Pseudomys dat voorkomt in Australië. Zijn verspreidingsgebied besloeg oorspronkelijk het zuidwesten van het Noordelijk Territorium, het noordwesten van Zuid-Australië en het midden van West-Australië, maar in de 19e eeuw stierf hij uit op het vasteland en is hij teruggedrongen tot Bernier Island, voor de westkust van West-Australië. Later is hij heringevoerd op Doole Island en Trimouille Island. Op Bernier komt hij het meeste voor op met Spinifex bedekte duinen.

De Alice Springs-muis is een grote, ruig behaarde muis. De rug is licht geelbruin, de onderkant wit, met een geleidelijke overgang. De staart is van boven grijs en van onderen wit, met een donkere borstel op de punt. De oren zijn grijs. De kop-romplengte bedraagt 90 tot 115 mm, de staartlengte 115 tot 125 mm, de achtervoetlengte 26 tot 27 mm, de oorlengte 19 mm en het gewicht 30 tot 50 gram. Vrouwtjes hebben 0+2=4 mammae.

De soort is 's nachts actief en leeft in nesten of kleine holen. Hij eet vooral groene planten, bloemen en wat geleedpotigen en schimmels. Jongen worden tussen mei en november geboren. Na een draagtijd van 28 dagen worden er vier of vijf jongen geboren, die na 30 dagen zelfstandig zijn. Op Bernier leven deze dieren ongeveer twee jaar.

De populaties op de eilanden worden soms als een aparte soort, Pseudomys praeconis, gezien, maar onderzoek heeft aangetoond dat de uitgestorven soort van het vasteland dezelfde is als het dier dat nog steeds op Bernier voorkomt. P. fieldi staat daarom door de IUCN als "kritiek" (CR) op de Rode Lijst; P. praeconis wordt - zonder uitleg - als een aparte soort gegeven.

Pseudomys fieldi ( Sueco )

fornecido por wikipedia SV


Pseudomys fieldi[2] är en däggdjursart som först beskrevs av Edgar Ravenswood Waite 1896. Pseudomys fieldi ingår i släktet australmöss, och familjen råttdjur.[3][4] IUCN kategoriserar arten globalt som sårbar.[1] Inga underarter finns listade i Catalogue of Life.[3]

Utseende

Denna gnagare blir ungefär 9,5 cm lång (huvud och bål) och har en cirka 12 cm lång svans. Den väger 30 till 50 g. Den långa pälsen har på ryggen en gulbrun färg med några gråa hår inblandade. Buken och fötterna är vitaktiga. Även svansen är mörk på ovansidan och ljus vid undersidan. Vid svansens spets finns en tofs.[5]

Utbredning och habitat

Arten fanns tidigare på flera öar i Shark Bay och på fastlandet i västra Australien. En ursprunglig population finns bara på Bernier Island kvar. 2002 startades ett försök för att återskapa populationen på Faure Island. Pseudomys fieldi vistas vanligen vid strandlinjer som är täckta av gräs och några buskar. Den besöker även hedområden och mangrove.[1]

Ekologi

Individer är främst aktiva på natten. De äter blad, blommor, insekter och ibland spindlar. Under fortplantningstiden skapas enkla underjordiska bon. Annars gömmer sig individerna i den täta växtligheten. Fortplantningssättet är främst känt från individer som hölls i fångenskap. Honor är cirka 28 dagar dräktig och föder vanligen tre ungar per kull, sällan upp till fem. Ungarna föds blinda och nakna. De öppnar sina ögon ungefär efter två veckor och diar sin mor fyra veckor. Cirka 100 dagar efter födelsen är ungarna lika stora som de vuxna djuren. Livslängen går upp till två år.[5]

Taxonomi

Arten beskrevs ursprungligen efter en individ (holotyp) som hittades nära Alice Springs. Populationen på Bernier Island beskrevs 1910 av Thomas som Pseudomys praeconis. Senare undersökningar visade att populationerna föreställer samma art.[2]

샤크만쥐 ( Coreano )

fornecido por wikipedia 한국어 위키백과

샤크만쥐(Pseudomys fieldi)는 쥐과에 속하는 설치류의 일종이다.[2] 오스트레일리아에서만 발견되며, 샤크 만 지역 4개 섬에서 제한적으로 서식한다. 한때 오스트레일리아 서부 2/3 전역에서 발견되었지만, 유럽인과 야생 동물의 이주 이후 서식 지역이 크게 줄었다. 분포 지역은 베르니에 섬의 해안가 모래 언덕으로 축소되고 심각한 멸종 위험 상태에 빠졌다. 2003년 오스트레일리아 야생자연보전협회(AWC, Australian Wildlife Conservancy)가 포레 섬에 일부 샤크만쥐를 방사하여 개체수가 늘기를 희망했다. 포식자 올빼미에도 불구하고, 재도입이 성공적이었으며 베르니에 섬보다 개체수가 빠르게 성장했고 멸종 위기에서 벗어났다.

화석 증거에 의하면, 샤크만쥐 분포 지역은 샤크만 지역부터 오스트레일리아 서부 해안가를 따라 이어지며[3] 더 멀리 내륙 건조 지역까지 확장된다.[4]
