Abstract The substantial body of research on Holarctic ground squirrels amassed over the past century documents considerable variability in morphological, cytogenetic, ecological, and behavioral attributes in the genus Spermophilus F. Cuvier, 1825. Recent molecular phylogenetic studies suggest that the traditionally recognized genera Marmota Blumenbach, 1779 (marmots), Cynomys Rafinesque, 1817 (prairie dogs), and Ammospermophilus Merriam, 1892 (antelope ground squirrels) render Spermophilus… 
A review of bristly ground squirrels Xerini and a generic revision in the African genus Xerus
TLDR
The phylogenetic reconstruction, based on the analysis of cytochrome b gene and including all known species of Xerini, confirms a deep divergence between the African taxa and the Asiatic Spermophilopsis.
Ground squirrels (Rodentia, Sciuridae) of the late Cenozoic Meade Basin sequence: diversity and paleoecological implications
TLDR
Faunal change through the sequence is interpreted as primarily reflecting a shift from a Pliocene assemblage of “southwestern” taxa with granivorous/omnivorous diets to a Pleistocene temperate assemblages of grazing taxa that either exhibited relatively high-crowned, transversely wider cheek teeth or were otherwise dependent on grassland habitats.
Towards a uniform nomenclature for ground squirrels: the status of the Holarctic chipmunks
TLDR
It is demonstrated that the chipmunk lineages diverged early in the evolution of the Marmotini, well before various widely accepted genera of marmotine ground squirrels.
Redescription and phylogenetic relationships of Spermophilus citelloides (Rodentia: Sciuridae: Xerinae), a ground squirrel from the Middle Pleistocene – Holocene of Central Europe
ABSTRACT Spermophilus citelloides is a poorly known Old World ground squirrel from the Middle Pleistocene – early Holocene of Central Europe that has only been briefly described previously. Here, we
Ancient hybridization and subsequent mitochondrial capture in ground squirrels (genus Ictidomys)
TLDR
Data suggested an ancient hybridization event during the Pleistocene, followed by capture of the I. tridecemlineatus mitochondrial haplotype by I. parvidens, and analyses of the SmcY gene supported contemporary hybridization at six localities.
Species limits and integrated taxonomy of the Idaho ground squirrel (Urocitellus brunneus): genetic and ecological differentiation
TLDR
The cohesion species concept is used to test whether both genetic and ecological data support species-level classification of U. b.
Across the great divide: revision of the genus Eupetaurus (Sciuridae: Pteromyini), the woolly flying squirrels of the Himalayan region, with the description of two new species
TLDR
It is suggested that the three widely disjunct populations of Eupetaurus are each sufficiently differentiated genetically and morphologically to be recognized as distinct species, two of which are described here as new.
Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Abstract Analyses of fur color patterns, morphometric data derived from external, cranial, and dental dimensions, and distributions of collection sites for voucher specimens form the basis for a
Phylogenetics and biogeography of the microendemic rodent Xerospermophilus perotensis (Perote ground squirrel) in the Oriental Basin of Mexico
TLDR
Climate cycles during the Pleistocene and the final uplift of the Trans-Mexico Volcanic Belt may have played a major role in early diversification in this lineage of Perote ground squirrel.

Phylogeny and Evolutionary History of the Ground Squirrels (Rodentia: Marmotinae)
TLDR
A phylogeny that includes all 43 currently recognized species in the two genera of ground squirrels as well as representatives of two closely related genera suggests that convergence in morphology has been a common theme in ground squirrel evolution.

Chromosomes and taxonomy of the ground squirrel subgenus Ictidomys.
TLDR
Taxonomic conclusions based on chromosomal characters agree closely with those based on characters of gross morphology and indicate that all three species are correctly classified as members of the same subgenus.

TLDR
