Bird species with similar effect traits maintain the temporal stability of community functions under disturbances of tropical cyclones

Climate change is altering the frequency and intensity of extreme climatic events such as tropical cyclones, raising concerns about ecological stability under such disturbances. This study examined how functional richness and redundancy influence the stability of two key ecological functions—insect predation and seed dispersal—in forest bird communities with contrasting histories of cyclone exposure. Using total biomass of insectivores and frugivores as functional indicators, we found that the stability of insect predation increased with redundancy in effect traits, whereas the stability of seed dispersal was associated with redundancy in both effect and response traits. In forests frequently exposed to cyclones, both functional groups occupied a smaller overall trait space, while frugivores showed greater trait similarity among individuals. These results suggest that stability in insect predation and seed dispersal under cyclone disturbances largely stems from the abundance of species ..., , # Data from: Bird species with similar effect traits maintain the temporal stability of community functions under disturbances of tropical cyclones

## Description of the data and file structure

In 2021 and 2022, we sampled transects at high-cyclone-frequency and low-cyclone-frequency sites. One sample was composed of three replicated surveys of each transect within a site, and the total number of individuals of each species detected was summed for each survey. We then calculated temporal stability and functional diversity along each transect per year, based on functional traits from the published dataset.
