The gray-headed lemur (Eulemur cinereiceps), or gray-headed brown lemur, is a medium-sized primate, a cathemeral species of lemur in the family Lemuridae. Until a taxonomic revision in 2008, it was known as the white-collared brown lemur or white-collared lemur (Eulemur albocollaris).[4] It lives in south-eastern Madagascar.[1] In 2005, satellite imagery estimates showed approximately 700 km2 (270 sq mi) of total remaining habitat within its geographic range.[5] It is highly threatened by hunting and habitat loss, and was considered to be among the 25 most endangered primates in 2006–2008.[6] It is currently listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) due to a highly restricted range,[1] and has been named one of "The World's 25 Most Endangered Primates."[7]

The gray-headed lemur is only found in southeastern Madagascar, from the Manampatrana River south to the Mananara River.[5][8]


Change in taxonomy


Recent genetic and morphological evidence has suggested that the former name, E. albocollaris, was actually a junior synonym of E. cinereiceps.[1] Consequently, the common name gray-headed lemur and the scientific name Eulemur cinereiceps were resurrected to replace white-collared brown lemur and E. albocollaris respectively.[4][9]

Previously, this species was listed as a subspecies of the common brown lemur until elevated to species status in 2001. However, genetic and field studies still support subspecies status under the biological species concept.[5]

Le Lémur à collier blanc, ou Lémur à tête grise ou encore Maki à fraise (Eulemur cinereiceps) est une espèce de primates lémuriformes de la famille des Lemuridae. Comme tous les lémuriens, il est endémique de l'île de Madagascar.

[it] Eulemur cinereiceps

Il lemure dalla testa grigia o lemure marrone dalla testa grigia (Eulemur cinereiceps A. Grandidier & Milne-Edwards, 1890) è una specie di lemure della famiglia Lemuridae, endemico del Madagascar sud-orientale.[1][3] Fino alla revisione tassonomica del 2008, era noto come lemure bruno dal collare bianco o lemure dal collare bianco (Eulemur albocollaris).[4] Nel 2005, le stime estrapolate dalle immagini satellitari hanno mostrato che rimangono solo circa 700 km² (270 miglia quadrate) di habitat totale all'interno dell'areale di questa specie.[5] Questa specie è fortemente minacciata dalla caccia e dalla perdita dell'habitat ed è stato considerato tra i 25 primati più a rischio tra il 2006 e il 2008.[6] Attualmente è elencato come in Pericolo Critico dall'Unione internazionale per la conservazione della natura (IUCN) a causa del suo areale ristretto,[1] ed è stato nominato uno dei " 25 primati più minacciati del mondo ".[7]
