Bathyergus suillus (Schreber, 1782) is a bathyergid commonly known as the Cape dune mole-rat. A solitarydwelling and sexually dimorphic species, it is the largest in body size of the African mole-rats, and 1 of 2 species within the genus. It is endemic to sandy soils of the southeastern and northwestern coastal regions of South Africa and the southwestern coast of Namibia. It is currently not o...

Peromyscus boylii (Baird, 1855), the brush deermouse, is a common cricetid rodent in the southwestern United States and Mexico. It is a member of the Peromyscus boylii species group and has had a complicated taxonomic history because many former subspecies have been elevated to species. It is a medium-sized Peromyscus with small ears and a long, slightly bicolored and slightly haired tail that ...

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...

Sexually receptive female Spermophilus beldingi (Rodentia: Sciuridae) usually mate with several different males. The paternity of 27 litters born in 1977 and 1978 was ascertained by combining field observations of mating with laboratory paternity exclusion analyses. Most of the litters (78 percent) were multiply sired, usually by two or three males. This may be the highest frequency of multiple...

The first well defined Pliocene mammalian faunas in the Czech Republic – found at localities Měňany 3 and Vitošov – are reported herein. Pilot samples from the localities have yielded an assemblage of at least 23 taxa of small mammals (Lipotyphla, Chiroptera, Lagomorpha, and Rodentia). The key taxa Mimomys hassiacus, M. cf. gracilis (an advanced form), Baranomys, and Germanomys in the assemblag...

Recent nuclear sequence analyses have provided evidence that primates and rodents are more closely related than previously believed (Madsen et al. 2001; Murphy et al. 2001a, 2001b). This proposal is difficult to reconcile with morphological insights (Liu et al. 2001; Novacek 2001) and is not generally supported by current mitochondrial sequence data (Reyes, Pesole, and Saccone 2000; Nikaido et ...
