Abstract There is a paucity of empirical data on gliding abilities of most gliding mammals, including flying squirrels in the genus Glaucomys. I assessed gliding performance of the northern flying squirrel (Glaucomys sabrinus) by calculating glide parameters for 100 glides observed between July 1999 and July 2000 in southern New Brunswick, Canada. G. sabrinus had a glide angle of 26.8° and a glide ratio of 1.98. The difference between the vertical drop at the start of a glide and the vertical… 

Gliding ability of the Siberian flying squirrel Pteromys volans orii

ABSTRACT Forest fragmentation is a threat to flying squirrel population due to dependence on gliding locomotion in forests. Therefore, it is essential to understand their gliding ability. The gliding

Gliding performance and its relevance to gap crossing by the squirrel glider (Petaurus norfolcensis)

TLDR
Parts of the gliding performance of the squirrel glider are described based on recorded parameters of 85 glides of 73 individuals, predicting that trees beside roads that create a tree-gap of 20 m (two-lane road) or 43‬m (four-laneRoad) will need to be a least 13 M and 25‬mile tall, respectively, to enable animals to safely glide across a road.

Gliding performance of the red giant gliding squirrel Petaurista petaurista in the tropical rainforest of Indian eastern Himalaya

TLDR
Forest structure has an influence on the gliding habits of gliding squirrels and thus the data on gliding parameters should be used when planning forest management actions.

Gliding performance in the yellow-bellied glider in low-canopy forest

TLDR
Parts of the glide performance of the yellow-bellied glider (Petaurus australis) are described based on 22 glides of 17 individuals within 20–30-m-high open forest in western Victoria to guide the management of habitat connectivity for yellow- Bellied gliders.

Gliding locomotion of Siberian flying squirrels in low-canopy forests: the role of energy-inefficient short-distance glides

Short glides of less than 20 m seem energy inefficient for the Siberian flying squirrel Pteromys volans as with the northern flying squirrel Glaucomys sabrinus. However, Siberian flying squirrels in

Home Range and Habitat Use of Northern Flying Squirrels in the Black Hills, South Dakota

Abstract Northern flying squirrels (Glaucomys sabrinus) of the Black Hills National Forest (BHNF) of South Dakota represent a unique and isolated population, but little is known about the home range

Experimental trials of the northern flying squirrel (Glaucomys sabrinus) traversing managed rainforest landscapes: perceptual range and fine-scale movements

TLDR
Although squirrels more often oriented towards the forest edge in clearcuts, they paused more often during their movements, which may lead to higher costs of dispersing through this habitat, and the application of the mass-based model to nonagricultural landscapes should be done with caution, and variables such as wind and illumination be measured concurrently.

Genetic structure of the arboreal squirrels (Glaucomys sabrinus and Tamiasciurus hudsonicus) in the North American Black Hills

TLDR
Constant patterns of genetic structure in northern flying and red squirrels indicate that other species' movements in the Black Hills may be affected by topography and habitat, and management practices and conservation measures are recommended to promote viability and survival of each species.

GLIDING BEHAVIOR OF JAPANESE GIANT FLYING SQUIRRELS (PETAURISTA LEUCOGENYS)

TLDR
Gliding behavior of Japanese giant flying squirrels, Petaurista leucogenys, was studied at Nara Park, Japan, and glide ratios and airspeeds were substantially lower than reported in other studies.

Locomotor performance and cost of transport in the northern flying squirrelGlaucomys sabrinus

TLDR
For glides of average length, cost of gliding was less than cost of quadrupedal locomotion except when the animals climbed to the launch point very slowly or ran quickly, so the hypothesis that gliding is less expensive than quadrupedAL locomotion is supported.

Glide angle in the genus Petaurus and a review of gliding in mammals

TLDR
An examination of the ratio of interorbital width to maximum skull width of gliding and nongliding possums was measured to examine whether gliders have eyes wider apart, to allow triangulation of distance in preparation for gliding.

Body Proportions and Gliding Adaptations of Flying Squirrels (Petauristinae)

TLDR
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.

WING TIP ANATOMY AND AERODYNAMICS IN FLYING SQUIRRELS

TLDR
Wing tips of flying squirrels are held at an upward angle to the rest of the wing and form airfoils and it is proposed that they serve the function of reducing induced drag, similar to the winglets of modern aircraft.

Anatomical and histological notes on the origin of the long accessory styliform cartilage of the Russian flying squirrel, Pteromys volans orii

TLDR
An anatomical and histological study of the long accessory styliform cartilage, which supports the flying membrane of the Russian (Siberian) flying squirrel, Pteromys volans orii, clarified that the flexor carpi ulnaris muscle attaches to the proximal end of the styliform Cartilage, suggesting that the styling is essentially homologous to the pisiform bone of other mammals.

Can Predation Explain Life-History Strategies in Mammalian Gliders?

TLDR
Longevity, reproduction, and mortality rates may indeed be interrelated, but the evidence provided by Holmes and Austad (1994) does not resolve the nature of this relationship for gliding mammals or clarify the relative role of metabolic constraints.
