title: Data from: Land-use change interacts with island biogeography to alter bird community assembly

description: Anthropogenic activities have reshaped biodiversity on islands worldwide.
 However, it remains unclear how island attributes and land-use change
 interactively shape multiple facets of island biodiversity through
 community assembly processes. To answer this, we conducted bird surveys in
 various land-use types (mainly forest and farmland) using transects on 34
 oceanic land-bridge islands in the largest archipelago of China. We found
 that bird species richness increases with island area and decreases with
 isolation, regardless of the intensity of land-use change. However,
 forest-dominated habitats exhibited lower richness than farmland-dominated
 habitats. Island bird assemblages generally comprised species that share
 more similar traits or evolutionary histories (i.e., functional and/or
 phylogenetic clustering) than expected if assemblages were randomly
 assembled. Contrary to our expectations, we observed that bird assemblages
 in forest-dominated habitats were more clustered on large and close
 islands, whereas assemblages in farmland-dominated habitats were more
 clustered on small islands. These contrasting results indicate that
 land-use change interacts with island biogeography to alter the community
 assembly of birds on inhabited islands. Our findings emphasize the
 importance of incorporating human-modified habitats when examining the
 community assembly of island biota, and further suggest that agricultural
 landscapes on large islands may play essential roles in protecting
 countryside island biodiversity.
