Abstract Bristly ground squirrels Xerini are a small rodent tribe of six extant species. Despite a dense fossil record the group was never diverse. Our 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. Genetic divergences among the African Xerini were of a comparable magnitude to those among genera of Holarctic ground squirrels in the subtribe… Expand

Social organization in a North African ground squirrel
TLDR
Light is shed on the ecological drivers of sociality, and the evolution of distinct social organizations in ground-dwelling sciurids, although the former are more temperate, seasonal breeders. Expand
Rodents and insectivores from the late Miocene of Romerales (Fortuna Basin, Southern Spain)
Abstract The Neogene Fortuna Basin (Murcia Region, SE Spain) is rich in microvertebrate sites. Its continental sections include localities extended from the middle Turolian (MN12) to the earlyExpand
On the shoulders of giants: Reginald Innes Pocock and integrative mammal research in museums and zoos
TLDR
Pocock’s ability to synthesize and integrate classical taxonomy with the then dominant polytypic species concept, utilizing both skull and external characters, of zoo and museum animals as unique opportunities for the advancement of mammal comparative biology are an enduring legacy that deserves to be better appreciated especially among European zoologists. Expand
Facts and misconceptions on the Palaearctic existence of the striped ground squirrel
TLDR
The modelled highly suitable habitat area for the striped ground squirrel in Morocco covers almost 690 km2 and only marginally overlaps the range for the species reported in the literature, indicating the heterogeneous effects on the determination of the occurrence of the species. Expand

Abstract The substantial body of research on Holarctic ground squirrels amassed over the past century documents considerable variability in morphological, cytogenetic, ecological, and behavioralExpand
A NEW PLIOCENE XERINE SCIURID (RODENTIA) FROM KOSSOM BOUGOUDI, CHAD
TLDR
The close affinities of Xerus daamsi with xerines which are currently living in northern savannas, more precisely in the Horn of Africa, suggests the presence of the Somali-Masai vegetation type in Chad by 5 Ma. Expand
Historical Biogeography and Body Form Evolution of Ground Squirrels (Sciuridae: Xerinae)
TLDR
A comprehensive approach integrating information from fossil records, morphological, molecular and geographical data of extant species, and events of paleoclimate and paleogeography, were used to explore the evolutionary processes in the Xerinae. Expand
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. Expand
Phylogeny and historical biogeography of African ground squirrels: the role of climate change in the evolution of Xerus
TLDR
The inferred phylogeny supports the hypothesized existence of an ‘arid corridor’ from the Horn of Africa to the Cape region and allopatric fragmentation as the cause of the deep divergences within this species. Expand
Sciurid phylogeny and the paraphyly of Holarctic ground squirrels (Spermophilus).
TLDR
DNA sequence data from the mitochondrial cytochrome b gene of 114 species in 21 genera is used to infer phylogenetic relationships among sciurids based on maximum parsimony and Bayesian phylogenetic methods and found the phylogeny of squirrels to be in substantial conflict with the current taxonomy. Expand
Nuclear DNA phylogeny of the squirrels (Mammalia: Rodentia) and the evolution of arboreality from c-myc and RAG1.
TLDR
A comprehensive molecular phylogeny for the family Sciuridae is reported on and Parsimony, likelihood, and Bayesian analyses reveal five major lineages and refute the conventional elevation of the flying squirrels (Pteromyinae) to subfamily status. Expand
Low, Complex and Probably Reticulated Chromosome Evolution of Sciuromorpha (Rodentia) and Lagomorpha
TLDR
It is proposed that reticulated evolution occurred during the diversification of Glires, which implies that several pericentric inversions and Robertsonian translocations were conserved in the heterozygous status for an extensive period, and concluded that a reticulation took place early during the evolution of both families and lasted longer in Sciuridae than in Leporidae. Expand
Close chromosomal congruence in two species of ground squirrel: Xerus inauris and X. princeps (Rodentia: Sciuridae)
TLDR
The species specificity of this marker in their zone of contact indicates an absence of gene flow between these taxa and gives credence to the recognition of X. inauris and X. princeps as two biologically distinct species. Expand
Karyotypic evolution of the family Sciuridae: inferences from the genome organizations of ground squirrels
TLDR
The results show that 1) the squirrels so far studied all have conserved karyotypes that resemble the ancestral karyotype of the order Rodentia; 2) the African ground squirrels could have retained the Ancestry of Sciuridae, and 3) the evolutionary rearrangements onto a molecular-based consensus phylogenetic tree of the family Sciur Families are mapped.
