The first genetic study of the holotype of the Gansu short-tailed shrew, Thomas, 1912, is presented. The mitochondrial analysis demonstrated that the type specimen of is close to several recently collected specimens from southern Gansu, northern Sichuan and Shaanxi, which are highly distinct from the two species of Asiatic short-tailed shrews of southern Sichuan, Yunnan, and Vietnam, and . Our analysis of four nuclear genes supported the placement of as sister to / , with the level of divergence between these two clades corresponding to that among genera of Soricinae. A new generic name, , is proposed for the Gansu short-tailed shrew. Karyotypes of (2 = 49, NF = 50) and (2 = 49, NF = 62) from southern Gansu are described. The tribal affinities of Blarinellini and Blarinini are discussed.

Blarinellini is a tribe of soricine shrews comprised of nine fossil genera and one extant genus. Blarinelline shrews were once widely distributed throughout Eurasia and North America, though only members of the Asiatic short-tailed shrew genus currently persist (mostly in southwestern China and adjacent areas). Only three forms of have been recognized as either species or subspecies.

Genetic diversity of the genus Blarinella was studied using one mitochondrial and four nuclear genes as examples. The first genotyping of shrews from the southeast of Gansu province (China), which is a typical habitat of B. griselda, has been performed.

Extensive organohalogen contamination in wildlife from a site in the Yangtze River Delta.

Sci Total Environ

June 2016

State Key Laboratory of Pollution Control and Resource Reuse, College of Environmental Science and Engineering, Tongji University, Shanghai 200092, China; Department of Environmental Science and Analytical Chemistry, Stockholm University, SE-106 91 Stockholm, Sweden; Swedish Toxicology Sciences Research Center (Swetox), Forskargatan 20, SE-152 57 Södertälje, Sweden.

The environmental and human health concerns for organohalogen contaminants (OHCs) extend beyond the 23 persistent organic pollutants (POPs) regulated by the Stockholm Convention. The current, intense industrial production and use of chemicals in China and their bioaccumulation makes Chinese wildlife highly suitable for the assessment of legacy, novel and emerging environmental pollutants. In the present study, six species of amphibians, fish and birds were sampled from paddy fields in the Yangtze River Delta (YRD) were screened for OHCs.
