By modifying habitats and creating bridges and barriers between landmasses, climate change and tectonic events are believed to have important consequences for diversification of terrestrial organisms. Such consequences should be most evident in phylogenetic histories of groups that are ancient, widespread, and diverse. The squirrel family (Sciuridae) is one of very few mammalian families endemic to Eurasia, Africa, and North and South America and is ideal for examining these issues. Through… 
Evolutionary consequences of Cenozoic climate change on African lacertid lizards (Squamata: Lacertidae)
TLDR
The effects of Cenozoic climate change on the taxonomic and morphological diversification of the Old World lizard family Lacertidae, with particular emphasis on the African radiation, are investigated, showing that African lacertids experienced three major peaks in diversification, accompanied by the evolution of suites of arid-adapted morphological traits.
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.
Spatiotemporal Diversification of Tree Squirrels: Is the South American Invasion and Speciation Really That Recent and Fast?
TLDR
The results indicate that tree squirrels entered South America at an earlier date than previously estimated, and it is concluded that the South American invasion was not as recent as previously inferred, but the diversification there was indeed very fast.
A biogeographic view on Southeast Asia's history
TLDR
S Sulawesi and its peculiar fauna is tested to test if a vicariant origin appears plausible for certain groups and when the remarkable fish and snail radiations found in the Malili Lakes system started to diversify, and a “tectonic dispersal” vicariance hypothesis from the Australian margin could not be refuted for three taxa.
Phylogeographic diversification of antelope squirrels (Ammospermophilus) across North American deserts
TLDR
The biogeographic history of antelope squirrels, genus Ammospermophilus, provides additional insight into the mechanisms that impacted diversification of arid-adapted taxa across the arid lands of western North America.
Earth History and the Evolution of Caribbean Bats
TLDR
The phylogenies indicate that several continental bat species descended from West Indian ancestors, as the exceptionally low sea level of the Miocene transitions allowed for two-way biotic exchange between the islands and the continent.
Differing rates of macroevolutionary diversification in arboreal squirrels
TLDR
A fossil-calibrated molecular-clock phylogeny of modern squirrel genera is used to estimate both rates of 'birth' and 'death', and the net rate of accumulation of lineages since the origin of the squirrel family (Sciuridae) 36 Ma.
The Evolution and Paleobiogeography of Flying Squirrels (Sciuridae, Pteromyini) in Response to Global Environmental Change
TLDR
This study compiles the worldwide fossils of Pteromyini to the species level in order to reproduce the spatiotemporal distribution pattern of flying squirrels and deduce the ancestral distribution according to dispersal-vicariance analysis of a phylogeny of the extant species.
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.

Rodent phylogeny and a timescale for the evolution of Glires: evidence from an extensive taxon sampling using three nuclear genes.
TLDR
Molecular datings based on three nuclear genes suggest that the rodent radiation took place at the transition between Paleocene and Eocene, and the association of Rodentia with Lagomorpha (the Glires clade), and a Glires + Euarchonta (Primates, Dermoptera, and Scandentia) clade is supported.

The first opening of the Bering Strait was an important palaeogeographical and biogeographical event for marine and terrestrial biotas in Asia and North America, and an oceanographic event of global

Abstract Fieldwork conducted since 1981 has greatly increased the sample of proboscidean fossils from Wadi Moghara, Egypt. The Moghara proboscidean assemblage is taxonomically more diverse than
Chronology of Fluctuating Sea Levels Since the Triassic
TLDR
An effort has been made to develop a realistic and accurate time scale and widely applicablechronostratigraphy and to integrate depositional sequences documented in public domain outcrop sections from various basins with this chronostratigraphic framework.
Is the Felsenstein zone a fly trap?
TLDR
Several criteria for identifying long-branch attraction are outlined and these criteria are applied to 18S ribosomal DNA (rDNA) sequence data for 13 insects.
Validity of Three Genera of Flying Squirrels: Eoglaucomys, glaucomys, and Hylopetes
TLDR
These hypotheses that Glaucomys sabrinus was more closely related to Hylopetes than to Glau-comys volans are contradicted and recognition of three distinct clades is supported.
The Chadronian Squirrel "Sciurus" Jeffersoni Douglass, 1901: A New Generic Name, New Material, and Its Bearing on the Early Evolution of Sciuridae (Rodentia)
TLDR
A new genus, Douglassia, is erected for the problematic Chadronian sciurid Sciurus jeffersoni Douglass, 1901, which differs from other sciurids in the retention of primitive dental and masseteric morphology.
Flying Squirrels Are Monophyletic
TLDR
It is shown that gliding evolved only once among squirrels and that the flying squirrels are a monophyletic group, and the manner of attachment of the patagium to the forelimb is different in each and demonstrates five morphologies differing from that of flying Squirrels.
