Spermophilus is a genus of ground squirrels in the squirrel family. [1] As traditionally defined the genus was very species-rich, ranging through Europe, Asia and North America, but this arrangement was found to be paraphyletic to the certainly distinct prairie dogs , marmots , and antelope squirrels .

The thirteen-lined ground squirrel (Ictidomys tridecemlineatus), also known as the striped gopher, leopard ground squirrel, and squinny (formerly known as the leopard-spermophile in the age of Audubon), is a species of hibernating ground squirrel that is widely distributed over grasslands and prairies of North America.

Spermophilus is a genus of ground squirrels in the squirrel family. [1] . In the past, this genus included many kinds of squirrels living in Europe, Asia, and North America. But scientists found that some squirrels in this genus were more closely related to prairie dogs, marmots, and antelope squirrels, which are clearly different.

Spermophilus citelloides, sometimes called the Pannonian souslik, [1] is an extinct species of ground squirrel in the squirrel family (Sciuridae). It was distributed in Central and Eastern Europe from the middle Pleistocene (Holsteinian) to the early Holocene.

Apr 14, 2009 · The sciurid genus Spermophilus F. Cuvier, 1825, is an excellent example of a well-studied genus that is in need of modern, integrative revision, and this paper is an attempt to provide such an overview for this varied group of ground squirrels.

Traditional multilocus phylogeny fails to fully resolve Palearctic ground squirrels (Spermophilus) relationships but reveals a new species endemic to West Siberia. Molecular Phylogenetics and Evolution 195: 108057. DOI: 10.1016/j.ympev.2024.108057 Reference page.

The ground squirrels were grouped in the genus Spermophilus until 2009 when the taxonomy was reviewed based on findings that this genus did not represent a monophyletic grouping. Spermophila were then reclassified into eight genera ( Helgen et al ., 2009 ).

The 38 species of North American ground squirrels and Eurasian sousliks (genus Spermophilus) are found from sea level to mountaintops in open habitats and occasionally in forests.

The European ground squirrel (Spermophilus citellus), also known as the European souslik, is a species from the squirrel family, Sciuridae. [2] It is among the few European species in the genus Spermophilus. Like all squirrels, it is a member of the rodent order.

Eu­ro­pean ground squir­rels (Sper­mophilus citel­lus) are na­tive to south­east Eu­rope. There are two main sec­tions of their dis­tri­b­u­tion.
