Franklin's ground squirrel
Franklin's ground squirrel (''Poliocitellus franklinii'') is a species of squirrel native to North America, and the only member of the genus ''Poliocitellus''. Due to the destruction of prairie, the populations of Franklin's ground squirrel have dwindled, approaching levels of concern. However, the species is prolific and locally abundant.〔
==Taxonomy==
Franklin's ground squirrel was first described by Joseph Sabine in 1822, who named it in honor of the British Arctic explorer Sir John Franklin.〔 It was formerly placed in the large ground squirrel genus ''Spermophilus'', in its own subgenus, ''Poliocitellus'', but since DNA sequencing of the cytochrome ''b'' gene has shown ''Spermophilus'' to be paraphyletic it is now placed in its own genus.〔〔 Franklin's ground squirrel is suggested to be sister to a clade containing not only the Mohave, round-tailed, spotted, and Perote ground squirrels (genus ''Xerospermophilus''), but the prairie dogs as well.〔〔 There are no commonly recognized subspecies.〔
