Species of lemur
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]
