Is dispersal easier than pollination? Two tests in New Zealand Loranthaceae

We tested the relative frequency of pollen limitation and dispersal limitation for two bird-pollinated and bird-dispersed New Zealand mistletoes, Peraxilla tetrapetala and Alepis flavida, at a South Island site where the bellbird (Anthornis melanura) is the sole pollinator and disperser. There was n...

Description
Summary:We tested the relative frequency of pollen limitation and dispersal limitation for two bird-pollinated and bird-dispersed New Zealand mistletoes, Peraxilla tetrapetala and Alepis flavida, at a South Island site where the bellbird (Anthornis melanura) is the sole pollinator and disperser. There was no evidence of dispersal limitation for P. tetrapetala over four seasons or A. flavida over two seasons. Few ripe fruits were present on plants at any one time (usually
