| Description: |
The adaptation of biological communities to urban environments is essential in ecological research. While current studies predominantly focus on alpha or beta diversity, community network perspective remain limited. Our research took birds as a model system to address: Do meta-community networks differ significantly between urban parks and conservation areas? Using functional traits, encompassing body mass, diet, and foraging strata, we compared betweenness, closeness, and degree centrality in bird meta-community across 128 urban parks and 129 conservation areas. We found that: 1) Closeness centrality was significantly higher in urban diet networks than in conservation areas. No significant differences were occurred in foraging stratum or body mass networks. 2) Betweenness centrality: Diet networks: nectarivores and terrestrial plant consumers showed the highest centrality at urban parks, while no significant hubs emerged in conservation areas. At foraging stratum perspective, aquatic dive-foraging group dominated urban systems, whereas aerial sallying birds served as key connectors in conservation areas. At body mass perspective, mini birds acted as hubs in urban parks, with no significant hubs in conservation areas. 3) Degree centrality showed no significant differences between habitats across all functional networks. Our results indicate that bird meta-community networks in urban parks exhibit slower information transfer and higher betweenness centrality hubs than conservation areas, suggesting greater structural vulnerability in urban networks. These distinct functional networks between urban and natural bird communities provide deep insights for urban ecology and biodiversity conservation. |
