Roe Deer (Capreolus capreolus)#Shorts #viral #shortsvideo

roe deer (Capreolus capreolus) also known as the roe, western roe deer, or European roe deer, is a species of deer. The male of the species is sometimes referred to as a roebuck. The roe is a small deer, reddish and grey-brown, and well-adapted to cold environments. The species is widespread in Europe, from the Mediterranean to Scandinavia, from Scotland to the Caucasus, and east to northern Iran and Iraq.

Linnaeus first described the roe deer in the modern taxonomic system as Cervus capreolus in 1758.The initially monotypic genus Capreolus was first proposed by John Edward Gray in 1821, although he did not provide a proper description for this taxon. Gray was not actually the first to use the name Capreolus, it has been used by other authors before him. Nonetheless, his publication is seen as taxonomically acceptable. He was generally ignored until the 20th century, most 19th-century works having continued to follow Linnaeus.

The name Capreolus capreolus is a tautonym.

Roe deer populations gradually become somewhat larger as one moves further to the east, peaking in Kazakhstan, then becoming smaller again towards the Pacific Ocean. The Soviet mammalogist Vladimir Sokolov had recognised this as a separate species from 1985 already using electrophoretic chromatography to show differences in the fractional protein content of the body tissues, the next year he showed that there were differences in the skull morphology, and a year after he used sonographs to demonstrate that the fawns, females and males made very different noises between species. Alexander S. Graphodatsky looked at the karyotypy to present more evidence to recognise these Russian and Asian populations as a separate species, now renamed the eastern or Siberian roe deer (Capreolus pygargus), in his 1990 paper.

The taxa are differentiated by the B chromosomes found in C. pygargus, populations of this species gain more of these strange 'junk' chromosomes as one moves further east.
