Key MethodThe phylogeny of flying squirrels was assessed, based on analyses of 80 morphological characters. Three published hypotheses were tested with constraint trees and compared with trees based on heuristic searches, all using PAUP*. Analyses were conducted on unordered data, on ordered data (Wagner), and on ordered data using Dollo parsimony. Compared with trees based on heuristic searches, the McKenna (1962) constraint trees were consistently the longest, requiring 8–11 more steps. The Mein (1970…Expand
Nuclear DNA phylogeny of the squirrels (Mammalia: Rodentia) and the evolution of arboreality from c-myc and RAG1.
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
Oldest skeleton of a fossil flying squirrel casts new light on the phylogeny of the group
The oldest fossil skeleton of a flying squirrel is reported that displays the gliding-related diagnostic features shared by extant forms and allows for a recalibration of the divergence time between tree and flying squirrels. Expand
Phylogeny of the Squirrels (Rodentia, Sciuridae)
A number of phylogenetic studies have been performed on the family Sciuridae. This work seeks to validate and extend existing phylogenetic studies of Sciuridae with an analysis of the divergenceExpand
Molecular Phylogeny of Rediscovered Travancore Flying Squirrel ( Petinomys fuscocapillus ) and its Conservation Implications
The phylogenetic analysis confirms that the P. fuscocapillus and Petinomys setosus (Temminck’s flying squirrel) are sister taxa and share most recent common ancestry. Expand
A review of the descriptions of fossil flying squirrels reveals few convincing arguments that these animals actually belong to the Pteromyini and none to support the hypothesis that they were gliding animals. Expand
Phylogenetic position of the small Kashmir flying squirrel, Hylopetes fimbriatus (≡ Eoglaucomys fimbriatus), in the subfamily Pteromyinae
The phylogenetic relationships of flying squirrels (Pteromyinae) were studied by obtaining complete sequence data from the mitochondrial cytochrome b gene of eight Old World and two New World flyingExpand
How to make a flying squirrel: Glaucomys Anatomy in Phylogenetic Perspective
Molecular evidence strongly supports the derivation of flying squirrels from tree squirrels, with the sister group being the Holarctic tree Squirrels (Sciurus) and their close relatives and the genetic changes that have produced these morphological modifications may facilitate the evolution of gliding flight. Expand
A Brief History of the New World Flying Squirrels: Phylogeny, Biogeography, and Conservation Genetics
Quaternary climatic fluctuations and associated changes in the location and extent of forest habitats appear to have been important factors in promoting early evolutionary diversification within the genus; structuring of intraspecific patterns of genetic variation; and producing geographically isolated peripheral populations in high-elevation habitats at the southern extremes of each species' range.

Flying squirrels are capable of gliding and one of the least known mammals of the world. Work on these animals is less and sporadic due to their crepuscular and cryptic habits. At the presentExpand
Relationships of diversity, disparity, and their evolutionary rates in squirrels (Sciuridae)
It is found that species richness and speciation rates are not correlated with clade age or with each other, and this results argue against a shared explanation for diversity and disparity in favor of geographically mediated mode of speciation and ecologically mediated modes of phenotypic evolution.

Phylogenetic Relationships among Six Flying Squirrel Gener,a Inferred from Mitochondrial Cytochrome b Gene Sequences
Molecular phylogenetic trees constructed by neighbor-joining and maximum likelihood methods strongly indicated the closer relationship between Hylopetes and Petinomys with 100% bootstrap values, suggesting the early radiation in the evolution of flying squirrels. Expand
Holarctic Evolution and Dispersal of Squirrels (Rodentia: Sciuridae)
Members of the rodent family Sciuridae occur on all continents except Australia. Squirrels are one of the few families of mammals to have such a nearly cosmopolitan distribution. However, patterns ofExpand
Flying Squirrels Are Monophyletic
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. Expand
Validity of Three Genera of Flying Squirrels: Eoglaucomys, glaucomys, and Hylopetes
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. Expand
Classification of mammals : above the species level
Malcolm C. McKenna and Susan K. McKenna inherited the project from Simpson and, with Bell, has constructed a completely updated hierarchical system that reflects the genealogy of Mammalia. Expand
Descriptive and Comparative Osteology of the Oldest Fossil Squirrel, Protosciurus (Rodentia: Sciuridae)
A nearly complete skeleton, recently discovered in early Oligocene deposits of Wyoming, repre¬ sents what may be the oldest fossil squirrel known and for the first time, this early squirrel can be compared fully with its extant relatives. Expand

The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters. Expand
Body Proportions and Gliding Adaptations of Flying Squirrels (Petauristinae)
Hang gliding seems to provide a good analogue for the gliding of flying squirrels, although the squirrels have lower aspect ratios (l.0 to 2.2) and lower glide ratios (less than 3) than do most hang gliders, and from this analogy it seems probable that the heavier “wing loading” of largeFlying squirrels does not affect the glide ratio but that the larger flying Squirrels must “fly” faster to maximize their glide ratio.

Douglassciurus, new name for Douglassia Emry and Korth, 1996, not Douglassia Bartsch, 1934
We recently proposed the generic name Douglassia for a species of fossil squirrel (Sciuridae, Rodentia) from the latest Eocene of western North America (Emry and Korth, 1996). The species wasExpand
Comparative myology of the forelimb of squirrels (Sciuridae)
The forelimb anatomy of flying squirrels is the most derived and differs from that of tree squirrels in details of shoulder, arm, and forearm musculature, and many of the differences suggest a variety of changes in function that are amenable to further study. Expand
