- Summary:
-
I show that the endangered short-tailed bat (Mystacina tuberculata) is considerably more important as a pollinator than previously considered, and contributes more than birds to the pollination of some species. While bird-specialized plants like Alseuosmia macrophylla are highly pollen limited in the absence of endemic birds, recent-colonist birds and mammals (principally silvereyes, Zosterops lateralis, and invasive ship rats, Rattus rattus ) compensate for the loss of endemic pollinators in the case of three brush-inflorescence species, thus partially maintaining pollination function.
The existence of offshore island refuges in New Zealand that retain species which have been lost on the adjacent main North and South islands provides a unique opportunity to compare the functioning of ecosystem processes before and after species extinctions. Many endemic, flower-visiting, vertebrate species are locally extinct in the north of the North Island, but still occur on Little Barrier Island---an offshore island reserve. I quantified the importance of these vertebrate species as pollinators on Little Barrier Island, and assessed the consequences of the loss of these species on the adjacent North Island. I show that birds and bats are important pollinators in native forest systems, not just for flowers that specialize on bird pollinators, but also for more generalist flower species.
