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.
