Myodes Rufocanus
The grey red-backed vole or the grey-sided vole (''Myodes rufocanus'') is a species of vole. An adult grey red-backed vole weighs 20-50 grams. This species ranges across northern Eurasia, including northern China, the northern Korean Peninsula, and the islands of Sakhalin and Hokkaidō. It is larger and longer-legged than the northern red-backed vole (''Myodes rutilus''), which covers a similar range and it is also sympatric with the Norwegian lemming (''Lemmus lemmus''). Description The grey red-backed vole has a reddish-coloured back and grey sides. It has a head and body length of and a tail length of .

Sundevall
Carl Jakob Sundevall (22 October 1801, Högestad – 2 February 1875) was a Swedish zoologist. Sundevall studied at Lund University, where he became a Ph.D. in 1823. After traveling to East Asia, he studied medicine, graduating as Doctor of Medicine in 1830. He was employed at the Swedish Museum of Natural History, Stockholm from 1833, and was professor and keeper of the vertebrate section from 1839 to 1871. He wrote ''Svenska Foglarna'' (1856–87) which described 238 species of birds observed in Sweden. He classified a number of birds collected in southern Africa by Johan August Wahlberg. In 1835, he developed a phylogeny for the birds based on the muscles of the hip and leg that contributed to later work by Thomas Huxley. He then went on to examine the arrangement of the deep plantar tendons in the bird's foot. This latter information is still used by avian taxonomists. Sundevall was also an entomologist and arachnologist, for which (for the latter field) in 1833 he publis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
