Fauna of fur mites of the genus Schizocarpus Trouessart, 1896 (Acariformes: Chirodiscidae) associated with the Eurasian beaver Castor fiber L. (Rodentia: Castoridae) in the beaver farm of Voronezh National Reserve (Russia) was examined. Totally, 16 Schizocarpus spp. were recorded. Among them 11 species were previously described by Dubinina (1964) from the same locality and four following recove...

Development of nine new microsatellite loci for the American beaver, Castor canadensis (Rodentia: Castoridae), and cross-species amplification in the European beaver, Castor fiber.

We developed nine new nuclear dinucleotide microsatellite loci for Castor canadensis. All loci were polymorphic, except for one. The number of alleles ranged from two to four and from five to 12 in populations from Arizona and Wisconsin, respectively. Average heterozygosity ranged from 0.13 to 0.86 per locus. Since cross-species amplification in Castor fiber was successful only in four loci, we...

Re-Evaluation of Sinocastor (Rodentia: Castoridae) with Implications on the Origin of Modern Beavers

The extant beaver, Castor, has played an important role shaping landscapes and ecosystems in Eurasia and North America, yet the origins and early evolution of this lineage remain poorly understood. Here we use a geometric morphometric approach to help re-evaluate the phylogenetic affinities of a fossil skull from the Late Miocene of China. This specimen was originally considered Sinocastor, and...

The beaver (Mammalia, Castoridae) from the Miocene of Sandelzhausen (southern Germany)

The Early/Middle Miocene boundary locality Sandelzhausen (MN5, southern Germany) yielded three beaver teeth: one lower incisor fragment and two strongly worn upper premolars, a right and a left one. The latter are so similar in wear, height, size, and enamel pattern that they probably represent one individual. Although the teeth have been referred to Chalicomys jaegeri Kaup, 1832 (e.g., Huguene...

Mites of the genus Schizocarpus Trouessart, 1896 (Acariformes: Chirodiscidae) from the North American beavers (Castor canadensis) in Russia.

Four native species of parasitic mites belonging to the genus Schizocarpus Trouessart, 1896 (Acariformes: Chirodiscidae) are recorded on the North American beaver Castor canadensis Kuhl, 1820 (Rodentia: Castoridae) from Russia. Totally ten beavers from all three main geographically isolated populations of in Russia (Leningrad Province, Voronezh Biosphere Reserve (beaver farm) and Khabarovsk Ter...
