Relative Abundance of Northern Flying Squirrels and Red Squirrels in Different Forest Types, Black Hills, South Dakota
Northern flying squirrels (Glaucomys sabrinus) and red squirrels (Tamiasciurus hudsonicus) in the Black Hills National Forest (BHNF) of South Dakota represent isolated populations. Because data on both species in the region are limited, and because the northern flying squirrel in South Dakota and the Black Hills National Forest has species of concern status, we trapped throughout BHNF to determ...
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 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 کاملThe 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 کاملHabitat Associations of Hypogeous Fungi in the Southern Appalachians: Implications for the Endangered Northern d Flying Squirrel (Glaucomys sabrinus coloratus)
-gporocarps of hypogeous mycorrhizal fungi (truffles) are the major food of northern flying squirrels (Gluucomys satinus). The two subspecies of northern flying squirrels that occur in the southern Appalachians, G. s. colmatus and G. s. fuscus, are endangered species which are primarily found in the ecotone between high-elevation spruce-fir and northern hardwood forests. Our objective was to de...
