Spatial segregation of species
Results from our new dataset included systematic recording of the three species that occur in south-east Queensland – P. alecto ,P. poliocephalus and P. scapulatus . The majority of observations were made of P. alecto , and P. poliocephalus , which occupy this region continuously through the year. P. scapulatus was found irregularly at some roosts, which is consistent with the seasonal migration patterns of this species (Nelson 1965a). Fine-scale spatial overlap between species was evaluated during surveys when multiple species were present (N=73, 70.2% of surveys). Black and grey-headed flying-foxes co-occurred in 65 surveys (62.5%), black and little red flying-foxes co-occurred in 17 surveys (16.3%), and grey-headed and little red flying-foxes co-occurred in 9 surveys (8.7%). We observed roost-dependent support for spatial segregation of species.
