“…However, European ground squirrel colonies at higher altitudes are not common, unlike the Asia Minor ground squirrel (Spermophilus xanthoprymnus), which prefers elevations from 800 to 2900 m a.s.l. (Gür and Gür, 2010).…”

Climatic and relief factors could limit the distribution of nonmigratory animals, and especially those that inhabit temperate areas. The limitations are stronger for habitat specialist species and a good understanding of these influences can contribute significantly to the development of conservation measures to protect them. The European ground squirrel (Spermophilus citellus) is a small mammal inhabiting pastures and areas of short herbaceous vegetation from Central and Southeastern Europe with limited data about their colony site selectivity. During the first wide survey of the European ground squirrel in Eastern Romania we identified a strong influence of annual precipitation, aspect, slope, vegetation height, and tree/bush coverage on the species' distribution and density. Lower precipitation values were associated with higher densities of European ground squirrel as well as slope. The same relationship was found with vegetation height and the amount of tree and bush coverage. The European ground squirrel uses areas with a southern and eastern aspect and slopes with a higher gradient. The elevation and the summer-winter temperatures do not have a significant influence on European ground squirrel colonies. Our results will contribute to the species' conservation across its distribution range and will help to determine the most appropriate sites for future relocation and repopulation programs.

“…Originally, the remains from Dursunlu and Emirkaya were identified as Spermophilus sp. Gür and Gür (2010) assume stability of the core habitats of S. xanthoprymnus in Asia Minor and conclude, these records probably represent this species because they are within the extant range of the Anatolian ground squirrel. (Kryštufek et al, 2009), N -Northern lineage (N1-12), S-Southern lineage (S1-14), J (J1-5) -Jakupica lineage, which can be considered as a part of the Southern lineage (Říčanová et al, 2013); (c) putative pathways of the expansion of S. citellus, based on Říčanová et al (2013), but modified to accommodate fossil data.…”

“…The extant Spermophilus xanthoprymnus is distributed in Anatolia and along the Anatolian borders of Iran and Armenia (Gür and Gür, 2010). Unfortunately, the fossil record of this species is poor and its remains are uncommon until the Holocene (Gromov et al, 1965).…”

“…Unfortunately, the fossil record of this species is poor and its remains are uncommon until the Holocene (Gromov et al, 1965). Gür and Gür (2010) mention remains from the Early Pleistocene of Dursunlu, Turkey (Güleç et al, 1999), and the Middle Pleistocene of Chios Island, Greece (Storch, 1975), Karain Cave, Turkey (Storch, 1988) and Emirkaya-2, Turkey (Montuire et al, 1994) (Fig. 5).…”

Ground squirrels were an important member of the Pleistocene steppe-tundra mammal community. They evolved ecological specialisations and exhibit behaviours that make them particularly informative subjects to study palaeoenvironmental constraints affecting species distribution and speciation. Interspecific competition and isolating geographical barriers are considered as the principal factors that define species range boundaries.The present paper provides a first comprehensive compilation of the living and extinct Spermophilus species in Europe. These data suggest 'patchwork quilt' model for the expansion and spatial distribution of ground squirrel species. Here we consider mainly small-sized Spermophilus species because large-sized (e.g., S. superciliosus) ground squirrels consist another 'patchwork quilt', which overlap the first one. This overlapping of the species ranges is possible because of the size difference that lowers interspecific competition (Hutchinson's rule).We consider two main types of range boundaries. One type includes roughly 'sub-parallel' boundaries that oscillate in concert with climatic and vegetational changes (a case of climatically controlled competitive exclusion). The other type consists of roughly 'sub-meridional' boundaries corresponding to geographical barriers (e.g., water barriers, mountain ridges); these boundaries are rather stable. Examples of 'sub-parallel range modifications include: oscillations of boundaries between S. pygmaeus and S. suslicus; the immigration of S. citellus into the Pre-Carpathian area; the branching of S. suslicus from S. pygmaeus; the regional appearance of the Late Pleistocene species S. severskensis and S. citelloides. Examples of 'sub-meridional events' are: the crossing of the Danube by S. citellus; the appearance of an isolated population of S. pygmaeus on right bank of the Dnieper during the Late Pleistocene to Middle Holocene; a crossing of the Dnieper river by S. pygmaeus, which resulted in the appearance of S. odessanus; the intrusion of eastern populations of S. pygmaeus into the Trans-Volga areas.

“…Compared to S. taurensis, diagnostic characters for S. citellus are as follows: less reddish dorsal pelage, underside more yellow, smaller body size (S. taurensis, range: 194-201 mm; S. citellus, range: 174-228 mm), tail slightly longer (S. taurensis, range: 62-65 mm; S. citellus, range: 31-90 mm) with a dark stripe along its dorsal side, and hind-foot length shorter (S. taurensis, range: 39-44 mm; S. citellus, range: 30-43 mm- Vohralík 2005, 2012;Gündüz et al 2007;Özkurt et al 2007). Compared to S. xanthoprymnus (see Gür and Gür 2010), diagnostic characters for S. citellus are as follows: the skull is less angular, back indistinctly spotted, and tail longer (S. xanthoprymnus, range: 30-72 mm; S. citellus, range: 31-90 mm) with black hairs dorsally Vohralík 2005, 2012). S. citellus, S. taurensis, and S. xanthoprymnus can be clearly distinguished on the basis of their alarm calls (Schneiderova´and Policht 2011a, 2011b.…”
