Environmental effects of solar-thermal power systems. Systematic status of the Mojave ground squirrel, Spermophilus mohavensis (subgenus Xerospermophilus)
The Mojave ground squirrel, Spermophilus mohavensis, is listed as a rare species by The California Fish and Game Commission. Its well-being has emerged as an environmental concern associated with deployment of solar thermal power systems in western parts of the Motave Desert. The more common round-tailed ground squirrel, Spermophilus tereticaudus, also occurs in the Mojave Desert, and this species closely resembles S. mohavensis. The systematic status of the sibling species was investigated using allozymic and chromosomal data. Karyotypically, the two species differ in diploid number while they share a level of genic similarity reported for other mammalian semispecies. Hybridization was detected only at a single disturbed site, while allelic introgression was confined to an estimated 60 km reach. The two taxa are retained as full biological species.
