Labrador wolf ( 英語 )

由wikipedia EN提供

The Labrador wolf (Canis lupus labradorius) is a subspecies of gray wolf native to Labrador and northern Quebec. It has been described as ranging in color from dark grizzly-gray to almost white,[4] and of being closely related to the Newfoundland wolf (C. l. beothucus).[5] This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005).[6]

History

Due to over-hunting in the early 1900s, Labrador wolf sightings were infrequent through the 1950s. Around that time period, the caribou population began to increase at a steady rate, which then correlated with an increase in the wolf population. However, the increase in number of the Labrador wolf was not enough to offset the continuing rise in caribou in the region, causing a reconsideration of the predation limitation hypothesis.[7]

In the late 2000s and early 2010s, there were several confirmed and unconfirmed sightings of the Labrador wolf on the island of Newfoundland.[8] In March 2012, a hunter shot and killed a large canine on the Bonavista Peninsula, thinking it to be a coyote; genetic testing found it to be a Labrador wolf.[8] In July 2012, a video posted on YouTube showed a canine which exhibited nearly all of the characteristics of a wolf. The video was taken in Clode Sound, Terra Nova National Park and was captured using a motion-sensitive trail camera set up as part of a joint research project on coastal river otters.[9] On 23 August 2012, the Newfoundland and Labrador Department of Environment and Conservation published the results of genetic testing of a large canine trapped on the Baie Verte Peninsula in 2009, confirming that this animal was also a Labrador wolf.[10]

Canis lupus labradorius ( 義大利語 )

由wikipedia IT提供

Il lupo del Labrador (Canis lupus labradorius Goldman, 1937) è una sottospecie di lupo grigio, Canis lupus, diffusa prevalentemente nel Labrador e nel Quebec settentrionale. Nel 1966 Peterson scrisse che il lupo del Labrador è «strettamente imparentato con... la razza estinta di Terranova, C. l. beothucus» [2] . La popolazione del lupo del Labrador è stabile, sebbene venga cacciato legalmente nel Canada settentrionale per la pelliccia [3] .

Fisiologia

Descrizione

Il lupo del Labrador pesa intorno ai 30 chili; le sue dimensioni, quindi, sono molto simili a quelle della maggior parte delle sottospecie di lupo [3] . Il mantello è di color grigio molto chiaro, tendente al bianco [2] , sebbene sia stato descritto anche come «grigio brizzolato scuro» [4] .

Nutrizione

Il lupo del Labrador caccia soprattutto cervi dalla coda bianca e caribù. Solo in pochissimi casi ha rivolto la propria attenzione al bestiame, attaccando bovini od ovini [3][5] .

Storia

In seguito alla caccia incontrollata che dovette subire agli inizi del XX secolo, la popolazione di lupo del Labrador diminuì sempre più, toccando il minimo negli anni '50. Attorno a quel periodo, la popolazione di caribù iniziò ad aumentare notevolmente e tale incremento portò a far aumentare di nuovo il numero dei lupi. Tuttavia, l'aumento del numero dei lupi non è stato sufficiente a compensare il continuo aumento dei caribù nella regione; ciò ha portato gli studiosi a dover riconsiderare altre ipotesi per giustificare il notevole incremento dei caribù [5] .

Serigala Labrador ( 馬來語 )

由wikipedia MS提供

Serigala Labrador (Canis lupus labradorius) ialah satu subspesies mungkin bagi serigala kelabu yang asli di Labrador dan di Quebec utara. Ia telah diperihalkan berwarna daripada kelabu gelap grizli hingga hampir putih,[3] dan berkait rapat dengan C. l. beothucus.[4]

Setakat 2005[update],[5] ia dianggap sebagai subspesies sah oleh MSW3, tetapi ia dikelaskan sebagai sinonim bagi C. l. nubilus oleh Perkhidmatan Ikan dan Hidupan Liar Amerika Syarikat.[6]

Sejarah

Oleh sebab perburuan berlebihan pada awal 1900-an, kekerapan C. l. beothucus yang dilihat adalah agak rendah pada sepanjang 1950-an. Pada sekitar jangka masa itu, populasi karibu mula meningkat pada kadar mantap, yang kemudian berhubung kait dengan peningkatan populasi serigala. Walau bagaimanapun, peningkatan bilangan serigala Labrador adalah tidak cukup untuk mengimbangi kebangkitan berterusan karibu di rantau berkenaan, menyebabkan pertimbangan semula hipotesis pengehadan pemangsaan.[7]

Pada hujung 2000-an dan awal 2010-an, terdapat beberapa penglihatan sah dan tidak sah bagi C. l. beothucus di pulau-pulau Newfoundland yang memeranjatkan oleh sebab serigala asli diburu sehingga pupus.[8] Pada Mac 2012, seorang pemburu menembak mati seekor kanin besar di Semenanjung Bonavista, menyangkakan bahawa ia merupakan seekor koyote; pengujian genetik bahawa ia merupakan C. l. beothucus.[8] Pada Julai 2012, satu video yang dipos di YouTube menunjukkan seekor kanin yang menunjukkan hampir semua ciri serigala. Video berkenaan dirakam di Clode Sound, Taman Negara Terra Nova, dan dirakam menggunakan tetapan kamera jejak peka pergerakan sebagai sebahagian daripada projek penyelidikan bersama terhadap berang-berang sungai pinggir laut.[9] Pada 23 Ogos 2012, Jabatan Alam Sekitar dan Pemuliharaan Newfoundland dan Labrador menerbitkan hasil pengujian genetik bagi seekor kanin besar yang diperangkap di Semenanjung Baie Verte pada 2009, mengesahkan bawah haiwan ini juga merupakan C. l. beothucus.[10]
