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 کاملFood-hoarding behavior of gray squirrels and North American red squirrels in the central hardwoods region: implications for forest regeneration
The North American red squirrel (Tamiasciurus hudsonicus) has expanded its geographic range into the state of Indiana concurrently with a decline in populations of gray squirrels (Sciurus carolinensis) throughout portions of the central hardwoods region of the United States that have been converted to intensive agriculture. Red squirrels construct larder hoards and function as seed predators th...
متن کاملMicrohabitat Associations of Northern Flying Squirrels in Burned and Thinned Forest Stands of the Sierra Nevada
—Prescribed burning and mechanical thinning are used to manage fuels within many western North American forest ecosystems, but few studies have examined the relative impacts of these treatments on forest wildlife. We sampled northern flying squirrels (Glaucomys sabrinus) and microhabitat variables in burned, thinned and control stands of mixed-conifer forest of the southern Sierra Nevada at the...
متن کاملDifferences in trapping mortality rates of northern flying squirrels
ROSENBERG, D. K., and ANTHONY, R. G. 1993. Differences in trapping mortality rates of northern flying squirrels. Can. J. Zool. 71: 660-663. We described trapping mortality rates of northern flying squirrel (Glaucomys sabrinus) populations in western Oregon, U.S.A., and evaluated the effects of sex, age, body mass, and number of times an individual was recaptured on these rates. Although the ove...
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...
