Gliding allows mammals to exploit canopy habitats of old-growth forests possibly as a means to save energy. To assess costs of quadrupedal locomotion for a gliding arboreal mammal, we used open-flow respirometry and a variable-speed treadmill to measure oxygen consumption and to calculate cost of transport, excess exercise oxygen consumption, and excess post-exercise oxygen consumption for nine northern flying squirrels (Glaucomys sabrinus) and four fox squirrels (Sciurus niger). Our results… 
Crouching to fit in: the energetic cost of locomotion in tunnels
Although tunnel locomotion requires a more striking change in posture for ferrets, ferrets are more efficient locomotors in both conditions than mammals of similar mass.
Arboreal Locomotion in Eurasian Harvest Mice Micromys Minutus (Rodentia: Muridae) The Gaits of Small Mammals
Findings indicate that, except for velocity and the way it is regulated, there are no significant differences in gait metrics between larger and smaller arboreal mammals, and the locomotor adaptations of Eurasian harvest mice represent behavioral mechanisms that promote stable, safe, and continuous navigation along slender substrates and ultimately contribute to the successful exploitation of the arBoreal milieu.
A comparison of locomotor performance of the semiarboreal Pacific marten (Martes caurina) and semiaquatic mustelids
Evaluated locomotor performance in a semiarboreal mustelid, the Pacific marten, and compared the results from three females and one male to those previously observed in semiaquatic mustelids, finding that at slower speeds, martens were less economical than predicted; at higher speeds,martens were as economical as predicted.
Arboreal locomotor and postural behaviour of European red squirrels (Sciurus vulgaris L.) in northern Greece
These results and those of previous research on the positional behaviour of other squirrels reveal several trends related to body size, arboreal or gliding habits and tropical or temperate forest distribution and contribute to the understanding of evolutionary novelty in multiple levels within the sciurid radiation.
Ecological and biomechanical insights into the evolution of gliding in mammals.
Comparative data suggest that the origins of gliding are often associated with shifts to low-quality diets including leaves and plant exudates, andKinetic data for both take-off and landing suggest that selection on these behaviors could also have shaped the evolution of glider.
Eurasian Red Squirrels Show Little Seasonal Variation in Metabolism in Food-Enriched Habitat
The scope of physiological seasonal adaptation is minimal when food is abundant and that squirrels instead rely on adjustments in activity to reduce exposure to low Ta, suggesting the squirrel’s success in a wide range of habitats, including urban areas, which require a rapid and flexible response to environmental changes.
Comparing the Arboreal Gaits of Muscardinus avellanarius and Glis glis (Gliridae, Rodentia): A First Quantitative Analysis
It is suggested that the observed differences in gait metrics may be related to body size and to the utilization of different microhabitats, reducing potential interspecific competition.
Running of the feathertail glider (Acrobates pygmaeus) on level ground: Gaits.
The feathertail glider (Acrobates pygmaeus) was chosen considering that the small size allows minor morphological modifications for aerial locomotion, and the gaits were studied on horizontal flat substrate which made it possible to compare running technique of the glider with that of terrestrial mammals.
Contrasting the realized and fundamental niche of the arboreal walking performance of neotropical rodents
This work investigates how allometric, phylogenetic, and adaptive components contribute to arboreal walking performance by 7 sigmodontine rodents of the Brazilian savanna and reveals a strong association between realized arborean walking performances (as inferred by proportion ofArboreal captures) and stride length and frequency.
Movement and Microhabitat Selection in the Southern Flying Squirrel (Glaucomys volans) in Southwestern Illinois
Radio-telemetry was employed to examine habitat use by Glaucomys volans (Southern Flying Squirrel) in urban and rural fragments in southwestern Illinois and found squirrels exhibited significant preference for medium and large trees over small trees.


Locomotory energetics and metabolic fuel reserves of the Virginia opossum.
It is concluded that aerobic, ground locomotion of Virginia opossums is associated with two major energetic handicaps because their particularly high cost of transport and the nature of the main oxidative fuel they consume are both incompatible with prolonged locomotion.
Locomotor performance and cost of transport in the northern flying squirrelGlaucomys sabrinus
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.
Running energetics of the North American river otter: do short legs necessarily reduce efficiency on land?
Energetic savings and the body size distributions of gliding mammals
This work uses published allometric relationships to determine an upper limit for body mass in mammalian gliders (flying squirrels, marsupial gliders, colugos and anomalurids) and compares favourably with published body mass distributions of independent glider faunas from Africa, Borneo and Australia.
Energetics of locomotion by the Australian water rat (Hydromys chrysogaster): a comparison of swimming and running in a semi-aquatic mammal.
The energetic costs of locomoting either in water or on land were high for the semi-aquatic Hydromys chrysogaster, however, the relative costs were lower than when an aquatic specialist attempts to move on land or a terrestrial specialist tries to swim.
Energetics and mechanics of terrestrial locomotion. I. Metabolic energy consumption as a function of speed and body size in birds and mammals.
This series of four papers investigates the link between the energetics and the mechanics of terrestrial locomotion using data from 62 avian and mammalian species to formulate a new allometric equation relating mass-specific rates of oxygen consumed during locomotion at a constant speed to speed and body mass.

S stride frequency and stride length of these elongate mustelids at the gait transition speed were similar to values predicted for conventionally-shaped mammals.
EPOC and the energetics of brief locomotor activity in Mus domesticus.
Excess post-exercise oxygen consumption (EPOC) is not affected by short exercise durations; EPOC is an important energetic consideration when Exercise durations are short; and the metabolic costs of brief, vigorous locomotion may be much higher than previously estimated.
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
Experimental trials of the northern flying squirrel (Glaucomys sabrinus) traversing managed rainforest landscapes: perceptual range and fine-scale movements
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.
