Rusa unicolor (Artiodactyla: Cervidae)
نویسنده
چکیده
Rusa unicolor (Kerr, 1792), or sambar, is the largest Oriental deer. Seven subspecies occur in varied habitats and elevations from India and Sri Lanka throughout southeastern Asia. Body mass and antler length decrease from west to east. R. unicolor is considered ancestral relative to the form of its male-only antlers and social behavior. Populations are vulnerable because of overexploitation for subsistence and markets in meat and antlers. R. unicolor was elevated by the International Union for Conservation of Nature and Natural Resources from no status in 2006 to ‘‘Vulnerable’’ in 2008 because of .50% decline in many populations over the past 3 generations. It is well represented in zoos and private collections and is introduced in Australia, New Zealand, South Africa, and the United States.

Encephalitis induced by a newly discovered ruminant rhadinovirus in a free-living Formosan sambar deer (Rusa unicolor swinhoei).
We documented a case of a free-living Formosan sambar deer (Rusa unicolor swinhoei) infected with a newly discovered ruminant Rhadinovirus (RuRv). Non-purulent encephalitis was the primary histological lesion of the sambar deer. We conducted nested PCR to screen for herpesvirus using generic primers targeting the DNA polymerase gene. In addition, we found that DNA polymerase gene of the sambar ...

In this study we compared the phylogeographic patterns of two Rusa species, Rusa unicolor and Rusa timorensis, in order to understand what drove and maintained differentiation between these two geographically and genetically close species and investigated the route of introduction of individuals to the islands outside of the Sunda Shelf. We analyzed full mitogenomes from 56 archival samples fro...
متن کاملCongenital cataract associated with persistent hyperplastic primary vitreous and persistent tunica vasculosa lentis in a sambar deer (Rusa unicolor) – clinical, ultrasonographic, and histological findings
Ultrasonography suggested the diagnosis of cataract associated with persistent fetal intraocular vasculature in a 26-day-old sambar deer. The deer was ill and died despite intense critical care. Globes were removed. Histological characteristics of persistent fetal vasculature and secondary cataract are reported expanding the knowledge of ophthalmic disorders in wild ungulates.
متن کاملIdentifying Mazama gouazoubira (Artiodactyla; Cervidae) chromosomes involved in rearrangements induced by doxorubicin
The process of karyotype evolution in Cervidae from a common ancestor (2n = 70, FN = 70) has been marked by complex chromosomal rearrangements. This ancestral karyotype has been retained by the current species Mazama gouazoubira (Fischer 1814), for which a chromosomal polymorphism (Robertsonian translocations and the presence of B chromosomes) has been described, presumably caused by a chromoso...

Przewalskium albirostre (Przewalski, 1883) is a physically unique cervid commonly called the white-lipped deer. Przewalskium is monotypic. This species is a high-elevation specialist endemic to the eastern Tibetan Plateau where it inhabits relatively open hills and mountains with a mosaic of forest edges, meadows, and shrublands. Populations of P. albirostre are highly fragmented and vulnerable...
