Dactylanthus taylorii is thought to be the only ground-flowering plant to be pollinated by a bat; the New Zealand lesser short-tailed bat (Mystacina tuberculata). This unique mutualistic relationship is poorly understood despite both species being threatened. We placed dataloggers around distinct clumps of D. taylorii inflorescences to monitor bats with implanted passive integrated transponders (PIT-tags) and quantify visitation rates and demography during the late-summer flowering season.
Recent work at several central South Island sites has shown that the bird-pollinated mistletoe Peraxilla tetrapetala (Loranthaceae) is extensively pollen-limited. We studied the diet, time-budget, and densities of its principal pollinator, bellbirds (Anthornis melanura, Meliphagidae), at Craigieburn to find out what aspect of bellbird ecology may be limiting pollination.
