Dispersal of autumn olive seeds by foxes on coal surface mines in
east Tennessee.
Fowler, LJ | Fowler, DK | Thomas, JE
Journal of the Tennessee Academy of Science. Vol. 57, no. 3-4, pp.
83-85. 1982.
Monthly scat collections and seed germination tests suggested that
foxes may be important in the dispersal of autumn olive (Elaeagnus
umbellata ) seeds on reclaimed coal surface mines. Analysis of 117
fox scats collected once monthly from November to April on a
Campbell County, Tennessee, minesite indicated that the average
number of autumn olive seeds per scat ranged from 0.3 seed in
April to 218.0 seeds in November. The highest number of seeds
recorded in a scat was 622. Germination tests of seeds removed
from fox scats and a control seed lot from the same site resulted
in germination percentages of all seed groups increasing with
longer lengths of stratification. The highest percentage
germination occurred at 12 weeks in the fox group and at 16 weeks
in the control group. Although germination of seeds from fox scats
averaged 17 percent lower than the control group, percentage
germination in the fox seed lot was sufficiently high (up to 75
percent) to allow dissemination of large quantities of viable
seeds by foxes.
