Glide 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 کاملMonoecocestus thomasi sp. n. (Cestoda: Anoplocephalidae) from the northern flying squirrel, Glaucomys sabrinus (Shaw), in Oregon.
Monoecocestus thomasi sp. n. (Cestoda: Anoplocephalidae), from the northern flying squirrel, Glaucomys sabrinus (Shaw), in Oregon, is described and distinguished from its congeners. Monoecocestus thomasi is the sixth species of Monoecocestus to be described from nearctic rodents, and the first from a member of the family Sciuridae. Our comparisons of taxonomic characters of the nominal species ...
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 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...
متن کاملExperimental trials of the northern flying squirrel (Glaucomys sabrinus) traversing managed rainforest landscapes: perceptual range and fine- scale movements
Successful dispersal in many species may be a function of the distance at which animals can perceive a particular landscape feature (i.e., perceptual range), as well as energetic costs associated with traversing the distance towards that feature. We used a model, relating perceptual range to body size of mammals, to predict the perceptual range of the northern flying squirrel (Glaucomys sabrinu...
