The influence of climatic oscillations during the Quaternary Era on the genetic structure of Asian black bears in Japan.

23 Mar 2009 The Asian black bear (Ursus thibetanus) inhabits two of the main islands, Honshu and Shikoku, in Japan. To determine how climatic oscillations during the Quaternary Era affected the genetic structure of the black bear populations in Japan, we ... Read more...

Deciphering the complete mitochondrial genome and phylogeny of the extinct cave bear in the Paleolithic painted cave of Chauvet.

25 Oct 2008 Retrieving a large amount of genetic information from extinct species was demonstrated feasible, but complete mitochondrial genome sequences have only been deciphered for the moa, a bird that became extinct a few hundred years ago, and for ... Read more...

Effects of cryopreservation on head morphometry and its relation with chromatin status in brown bear (Ursus arctos) spermatozoa.

6 Aug 2008 The Cantabrian brown bear (Ursus arctos) is a highly endangered species in Spain and basic studies are necessary in order to bank its germplasm. Sperm heads are mainly made up of chromatin, thus their shape depends partly on chromatin structure. ... Read more...
