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 fl..., Study sites
This study was conducted on Wanshan Island (continental island; 21°56′N, 113°44′E) and Yongxing Island (oceanic island; 16°49′N, 112°20′E). Wanshan Island belongs to the Wanshan archipelago (Zhuhai, Guangdong province, China) and was separated from the mainland due to the rising sea level during the Holocene (Wang, 2008). The distance between Wanshan Island and the city of Zhuhai is about 40 km. Yongxing Island belongs to the Xisha archipelago (Sansha, Hainan province, China), a group of coral islands (Paracel Islands) in the South China Sea that was formed in the Late Tertiary (Gong et al., 1996). The Yongxing Island is developed on coral reefs, and the distance between the archipelago and the southeast of Hainan Island of China is around 350 km. The areas of Wanshan and Yongxing islands are 8.2 km2 and 2.6 km2, respectively. Our field observations of plant–pollinator interactions were conducted from July 1 to August 30, 2018, on Yongxing Island and from July 1 to August 30..., , # Differences in plant–pollinator network structure and pollinator importance between a continental and an oceanic island community
