Seed Dispersal in Relation to Rodent Activities in Seral Big Sagebrush CommunitiesLa Tourrette, J. E.; Young, J. A.; Evans, R. A. (Society for Range Management, 1971-03-01)Heteromyid rodents play an active role in the dispersal of caryopses and seeds of herbaceous species in degraded big sagebrush communities. Collections of caryopses of downy brome, deposited in caches, influence the dynamics of the grass population and the diet of animals on range sites in winter. Seeds and caryopses of alien weeds and exotic wheatgrasses were recovered more frequently from the pouches of rodents than seeds of native species.
