The dissemination of prickly pear seed by jack rabbits
1942
Timmons, F.L.
The occurrence of prickly pear seeds in the droppings of jack rabbits that had fed upon the ripened fruits was determined from collections made in and near a cactus infested pasture at Hays, Kans. The droppings collected in the pasture contained an average of about 2.5 seeds per pellet, while those collected in nearby uninfested fields only occasionally contained seeds. The germination of the seeds found in the jack rabbit droppings was about 50% greater than that of seeds taken from dried fruits at the same time. Jack rabbits evidently are important agents in the dissemination of viable prickly pear seed and presumably in the spread of prickly pear plants through western Kansas pastures.
