Evidence

Peer-reviewed

Geography

Oʻahu, Hawaiʻi, USA

System

Island forest pollination network

## WHAT THE EVIDENCE SAYS

Field cameras and playback experiments at an endangered native aster found asymmetric interactions between two native honeycreepers: the more dominant ʻapapane altered the timing and frequency of ʻamakihi flower visits. The study shows that competitive behavior among native pollinators can shape access to a scarce floral resource even in a system dominated by broader invasive-species pressures.

## WHY IT MATTERS / OUR READ

Restoration planning in simplified island systems may need to retain interaction structure, not only species lists. Native species can compete as well as facilitate, and rare plant recovery may depend on how those interactions change around limited resources.

## CAVEATS / UNCERTAINTY

The work centers on one plant and two bird species in a localized setting. Flower visitation is not the same as realized pollen transfer, seed set or plant population growth, so the demographic consequence remains uncertain.
