Elseya

provided by wikipedia EN

Elseya is a genus of large side-necked turtles, commonly known as Australian snapping turtles, in the family Chelidae. Species in the genus Elseya are found in river systems in northern and northeastern Australia and throughout the river systems of New Guinea.[6] They are identified by the presence of alveolar ridges on the triturating surfaces of the mouth and the presence of a complex bridge strut.[7]

The Australian snapping turtles are largely herbivorous, with specialized mouth structures for eating fruits. However, they will eat animal products if opportunity arises. The various species can be found in large numbers where they are still abundant, e.g., Northern Territory of Australia. However, a number of the populations have become increasingly rare, and some are now listed as endangered.

Systematics

Etymology

John Edward Gray created the generic name, Elseya, in 1867 in honour of Dr. Joseph Ravenscroft Elsey, a surgeon-naturalist on the Gregory Expedition[8] that traversed northern Australia from the Victoria River to Moreton Bay in 1855–1856.

List of species

The genus was originally described by Gray in 1867 with the type species being set as Elseya dentata. The fossil genus Pelocomastes was later synonymised with this genus.[5] Following the recent revisions of this genus, the latisternum group has been moved to the new genus Myuchelys.[9] The remaining species of this genus have additionally been separated into three subgenera, Elseya, Pelocomastes, and Hanwarachelys, and the species redistributed among them.[10]

Extinct species

Fossil of Elseya uberrima

There are two identified extinct species of Elseya. Elseya nadibajagu Thomson & Mackness, 1999[20] and Elseya uberrima (De Vis, 1897)[21] are prehistoric species known only from fossils. E. lavarackorum was initially believed also to be a fossil taxon, but later discovered to be still extant.[7] Elseya nadibajagu is a Pliocene species of extinct Australian snapping turtle, described from the Bluff Downs region of Queensland, Australia.;[22] whereas Elseya uberrima is a Pleistocene species described from the Darling Downs region of Queensland, Australia.[23]

Notes

  1. ^ A binomial authority in parentheses indicates the species was originally described in a genus other than Pelusios.

Elseya ialah genus kura-kura leher sisi, yang dikenali sebagai Kura-kura Sentap Australia, dari keluarga Chelidae. Spesies dari genus Elseya biasanya ditemui di kawasan sungai utara Australia dan sepanjang laluan sungai New Guinea.[6] They are identified by the presence of alveolar ridges on the triturating surfaces of the mouth and the presence of a complex bridge strut.[7]

Mereka bersifat maun, dengan struktur mulutnya digunakan untuk mengunyah buah-buahan. Walau bagaimanapun, mereka juga menjadikan haiwan lain sebagai makanan. Kini, populasi haiwan ini semakin berkurangan dan ada yang dikelaskan sebagai haiwan terancam

Sistematik

Etimologi

John Edward Gray mencipta nama Genus Elseya, pada tahun 1867 sebagai penghormatan kepada Dr. Joseph Ravenscroft Elsey. Elsey seorang pakar bedah semulajadi semasa ekspedisi Augustus Charles Gregory [8] pada tahun 1855-56.

Spesies

Genus ini diperkenalkan oleh Gray pada 1867 dengan jenis spesiesnya terawal ialah Elseya dentata. Fosil genus Pelocomastes kemudiannya disinonimkan dengan genus ini.[4] Selepas disemak beberapa kali, kumpulan latisternum dipindahkan kepada genus baru, iaitu Myuchelys.[9] Beberapa spesies dari genus yang tinggal kemudiannya dipisahkan kepada tiga subgenus dan diagihkan dikalangan mereka.[10]

Elseya nadibajagu dan Elseya uberima ialah spesies prasejarah yang hanya diketahui melalui fosil. E. lavarackorum asalnya dikelaskan sebagai taksa fosil, yang kemudiannya dimasukkan sebagai taksa yang dikembangkan.[7]

Perhatian: Tatanama Binomial pada kurungan menunjukkan spesies ini pada mulanya dimasukkan ke dalam genus selain daripada Elseya.

Elseya ( Dutch; Flemish )

provided by wikipedia NL

Herpetologie

Elseya is een geslacht van schildpadden uit de familie slangenhalsschildpadden (Chelidae).[1] De groep werd voor het eerst wetenschappelijk beschreven door John Edward Gray in 1867.

Op de soort Elseya novaeguineae na, die in Nieuw-Guinea leeft, komen alle soorten voor in Australië. Alle soorten worden ook wel Australische bijtschildpadden genoemd, maar dit heeft geen relatie met de familie bijtschildpadden (Chelydridae). De schildpadden kunnen uitstekend zwemmen, en hebben een vrij plat, iets koepelvormig schild en goed ontwikkelde zwemvliezen tussen de tenen.

De habitat bestaat uit poelen, rivieren, meren en andere grotere wateren, op het menu staan vooral planten, maar ook kleine ongewervelden worden gegeten, zowel in het water als op het land.

Taxonomie

Er zijn zeven moderne soorten, ook is een uitgestorven soort bekend; Elseya uberima.

Geslacht Elseya

Elseya ( Portuguese )

provided by wikipedia PT

Elseya é um gênero de cágados, comumente conhecidos como cágados australianos, na família Chelidae. Espécies do gênero Elseya são encontradas em sistemas fluviais no norte e no nordeste da Austrália e em todos os sistemas fluviais da Nova Guiné.[2] Eles são identificados pela presença de cristas alveolares nas superfícies de trituração da boca e com a presença de um braço da ponte complexo.[3]

Os cágados mordedores australianos são em grande parte herbívoros, com estruturas na, boca especializadas para comer frutas. Entretanto, comerão produtos animais se a oportunidade se levantar. As várias espécies podem ser encontradas em grande número onde são ainda abundantes, por exemplo, Território do Norte da Austrália. No entanto, algumas populações tornaram-se cada vez mais raras, e algumas estão agora listadas como ameaçadas de extinção.

Sistemática

Etimologia

John Edward Gray criou o genérico nome, Elseya, em 1867 em homenagem ao Dr. Joseph Ravenscroft Elsey. Elsey foi um cirurgião naturalista na Expedição Gregory[4] que atravessou o norte da Austrália do Rio de Victoria até Moreton Bay em 1855-56.

Espécies

O gênero foi originalmente descrito por Gray em 1867 com o Espécie-tipo sendo definido como Elseya dentata. O gênero fóssil Pelocomastes foi mais tarde sinônimo com este gênero.[5] Após as revisões recentes deste gênero, o grupo latisternum foi movido para O novo gênero Myuchelys.[6] As espécies restantes deste gênero foram posteriormente separadas em três subgêneros e as espécies redistribuídas entre eles.[7]

Elseya nadibajagu e Elseya uberima São espécies pré-históricas conhecidas apenas por fósseis. E. lavarackorum Foi inicialmente chamado para ser um taxon fóssil, mas descobriu-se mais tarde um ser atual.[3]

Elseya: Brief Summary ( Portuguese )

provided by wikipedia PT

Elseya é um gênero de cágados, comumente conhecidos como cágados australianos, na família Chelidae. Espécies do gênero Elseya são encontradas em sistemas fluviais no norte e no nordeste da Austrália e em todos os sistemas fluviais da Nova Guiné. Eles são identificados pela presença de cristas alveolares nas superfícies de trituração da boca e com a presença de um braço da ponte complexo.

Os cágados mordedores australianos são em grande parte herbívoros, com estruturas na, boca especializadas para comer frutas. Entretanto, comerão produtos animais se a oportunidade se levantar. As várias espécies podem ser encontradas em grande número onde são ainda abundantes, por exemplo, Território do Norte da Austrália. No entanto, algumas populações tornaram-se cada vez mais raras, e algumas estão agora listadas como ameaçadas de extinção.
