“…Harrison et al (2003) had earlier dated this same event to 10-14 Mya. In the timetree of Ge et al (2014), no currently recognized crown for ground squirrel or marmot genera has a 95% CI that even overlaps with the most recent of the chipmunk divergences; all divergences among living ground squirrel lineages took place subsequently, mainly during the late Miocene.…”

“…The remarkable diversity of social systems among ground squirrels and marmots has invited phylogenetic analyses to document their historical relationships (e.g., Harrison et al 2003), inadvertently uncovering paraphyly in some widely recognized groups (Herron et al 2004). Recently, the ground squirrel genus Spermophilus was revised to eliminate its paraphyly with respect to both prairie dogs (Cynomys) and marmots (Marmota).…”

Towards a uniform nomenclature for ground squirrels: the status of the Holarctic chipmunks

Abstract:The chipmunks are a Holarctic group of ground squirrels currently allocated to the genus Tamias within the tribe Marmotini (Rodentia: Sciuridae). Cranial, postcranial, and genital morphology, cytogenetics, and genetics each separate them into three distinctive and monophyletic lineages now treated as subgenera. These groups are found in eastern North America, western North America, and Asia, respectively. However, available genetic data (mainly from mitochondrial cytochrome b) demonstrate that the chipmunk lineages diverged early in the evolution of the Marmotini, well before various widely accepted genera of marmotine ground squirrels. Comparisons of genetic distances also indicate that the chipmunk lineages are as or more distinctive from one another as are most ground squirrel genera. Chipmunk fossils were present in the late Oligocene of North America and shortly afterwards in Asia, prior to the main radiation of Holarctic ground squirrels. Because they are coordinate in morphological, genetic, and chronologic terms with ground squirrel genera, the three chipmunk lineages should be recognized as three distinct genera, namely, Tamias Illiger, 1811, Eutamias Trouessart, 1880, and Neotamias A. H. Howell, 1929. Each is unambiguously diagnosable on the basis of cranial, post-cranial, and external morphology.

“…Age estimates were also calculated in a Bayesian framework as implemented in the mcmctree package included in PAML version 4.1, using an age interval between 7 and 11 MYA for the root of the tree. Irwin et al (1991) have shown that generally in mammals 3rd codon transversions in cytochrome b evolve at around 0.5% per million year and Harrison et al (2003) found the same value for ground squirrels. However, substitution rates in rodents may be much higher than other mammals (e.g.…”

“…The DNA was extracted using a QIAamp DNA Mini Kit (Qiagen, Valencia, CA, USA). The cytochrome b gene (cyt b) was amplified partially with primers H15319Marv, L15162Marv, L15408Marv (Haynes et al 2003), H15752 (Ohdachi et al 2006), L15702 (Harrison et al 2003), L14727-SP, and H15915-SP (Jaarola and Searle 2002). The alignment of the three fragments yielded the sequence data for a partial cyt b gene (1104 bp).…”

Mitochondrial sequences point on a cryptic species in five-toed jerboas, subgenus Paralactaga

Abstract:We addressed the species taxonomy of five-toed jerboas (Allactaga, subgenus Paralactaga) in the Middle East by applying molecular markers (cytochrome b and a partial 16S rRNA). The study consisted of 17 specimens from eight localities in the Middle East, representing both species: Allactaga euphratica and Allactaga williamsi. The phylogenetic reconstructions yielded three highly divergent lineages, which failed to conform to the recent taxonomy of Paralactaga. The first lineage (williamsi lineage) encompassed all the samples of A. williamsi from Turkey and Iran and also the specimens of A. euphratica from Lebanon. The haplotypes of A. euphratica were arranged into two lineages, which showed strong geographic associations. One lineage contained samples from Harran in Turkey and from Iran, while all the samples from Syria clustered in another lineage. The pairwise Kimura twoparameter values suggested similar divergences between the three lineages and were within the range reported for a sister species of rodents. Our results point to a cryptic species in A. euphratica and also provide evidence of the expanded range of A. williamsi further south to Lebanon.
