Abstract

Knowledge of the role of non-flying mammals in the pollination of the Australian flora is still incomplete. We captured non-flying mammals visiting Banksia ericifolia in north-east New South Wales and sampled pollen from their heads. The grassland melomys (Melomys burtoni) was captured >4 times more often than the house mouse (Mus musculus) or the swamp rat (Rattus lutreolus). Nocturnal pollen loads (mean 295 ± 53 grains) measured on the melomys are among the highest for an Australian non-flying mammal. Pollen removal from flowers at night was widespread. These observations suggest the grassland melomys is likely to play an important role in the pollination of subtropical B. ericifolia.

Keywords: banksia anthesis, banksia pollination, canopy live-trapping, flower visitors, mammal pollination, non‐flying mammal pollination, pollen smears, rodent pollination.
