Data from: Differences in plant–pollinator network structure and pollinator importance between a continental and an oceanic island community

Pollination is an important ecological process for plant reproduction.
Understanding the differences in plant–pollinator interactions and
pollinator importance across spatial scales is vital to determine the
responses of these interactions to global changes. Continental and oceanic
island systems provide us with an ideal model to examine the variation in
plant–pollinator interactions. Here, we compared the differences in
species composition, plant–pollinator network structure, and pollinator
importance in communities between a continental island (Wanshan Island)
and an oceanic island (Yongxing Island) in China. The results reveal
highly dissimilar species composition between continental and oceanic
islands that caused highly different plant–pollinator network structures.
In particular, the oceanic island networks had higher network connectance,
nestedness, and specialization than the continental island networks. For
plants co-occurring on both islands, pollinator species richness and
flower visitation rate were higher on the continental island than on the
oceanic island. Plant niche overlap was higher on the oceanic island than
on the continental island, while pollinator niche overlap was higher on
the continental island than on the oceanic island in both entire network
and co-occurring plant species subnetwork. Hymenoptera was the most
important pollinator group in the continental island community, while
Apidae was the most important in the oceanic island community. The results
imply that oceanic island communities may be less vulnerable to
disturbance, such as habitat alteration or destruction, than continental
island communities, and provide implication insights into biodiversity
conservation for pollinators on islands.
