The chromosomes of the New World flying squirrels (Glaucomys volans and Glaucomys sabrinus) with special reference to autosomal heterochromatin.
There are two species of New World flying squirrels included in the genus Glaucomys: G. sabrinus, the northern flying squirrel, and G. volans, the southern flying squirrel. During a study of local rodents around Hanover, New Hampshire, several flying squirrels were caught and their chromosomes were analyzed. The occurrence, in this region, of both species allowed a comparative study of their re...
متن کاملGlide performance and aerodynamics of non-equilibrium glides in northern flying squirrels (Glaucomys sabrinus).
Gliding is an efficient form of travel found in every major group of terrestrial vertebrates. Gliding is often modelled in equilibrium, where aerodynamic forces exactly balance body weight resulting in constant velocity. Although the equilibrium model is relevant for long-distance gliding, such as soaring by birds, it may not be realistic for shorter distances between trees. To understand the a...
متن کاملEffects of southern flying squirrels Glaucomys volans on red-cockaded woodpecker Picoides borealis reproductive success
Anecdotal data gathered from many populations suggest that southern flying squirrel (SFS, Gluucomys volans) use of the endangered red-cockaded woodpecker’s (RCW, Picoides borealis) nest and roost cavities may negatively affect RCW populations. We conducted a controlled experiment to determine the effects of SFSs on RCW reproductive success. During the 1994 and 1995 breeding seasons, SFSs were r...
متن کاملTake-off and landing forces and the evolution of controlled gliding in northern flying squirrels Glaucomys sabrinus.
Flying squirrels are well known for their ability to glide between trees at the top of a forest canopy. We present experimental performance and behavioural evidence that flight in flying squirrels may have evolved out of a need to control landing forces. Northern flying squirrels were filmed jumping from a horizontal branch to a much larger vertical pole. These were both slightly compliant (les...
متن کاملUltrasonic Vocalizations Emitted by Flying Squirrels
Anecdotal reports of ultrasound use by flying squirrels have existed for decades, yet there has been little detailed analysis of their vocalizations. Here we demonstrate that two species of flying squirrel emit ultrasonic vocalizations. We recorded vocalizations from northern (Glaucomys sabrinus) and southern (G. volans) flying squirrels calling in both the laboratory and at a field site in cen...
