Data from: Urbanization alters the spatiotemporal dynamics of plant-pollinator networks in a tropical megacity

Urbanization is a major driver of biodiversity change but how it interacts
with spatial and temporal gradients to influence the dynamics of
plant-pollinator networks is poorly understood, especially in tropical
urbanization hotspots. Here, we analyzed the drivers of environmental,
spatial, and temporal turnover of plant-pollinator interactions
(interaction β-diversity) along an urbanization gradient in Bengaluru, a
South Indian megacity. The compositional turnover of plant-pollinator
interactions differed more between seasons and with local urbanization
intensity than with spatial distance, suggesting that seasonality and
environmental filtering were more important than dispersal limitation for
explaining plant-pollinator interaction β-diversity. Furthermore,
urbanization amplified the seasonal dynamics of plant-pollinator
interactions, with stronger temporal turnover in urban compared to rural
sites, driven by greater turnover of native non-crop plant species (not
managed by people). Our study demonstrates that environmental, spatial,
and temporal gradients interact to shape the dynamics of plant-pollinator
networks and urbanization can strongly amplify these dynamics.
