Pollinators and urban riparian vegetation: important contributors to urban diversity conservation

Abstract Background Urbanization process around the world has not only changed patterns of land use, but also fragmented habitat, resulting in significantly biodiversity loss. Urban rivers, serve as one natural corridors urban ecosystems, are importance for ecosystem stability. However, few studies have been done to explore relationship between vegetation and pollinators river segments. In this study, two streams city Chongqing were selected study area, riparian vegetation, butterflies bees investigated along all four seasons a year illustrate spatial temporal distribution patterns. Simultaneously, ecological functions corridor analyzed. Result 109 plant species belonging 95 genera 39 families recorded; number sampled 12 13, respectively. The diversity among butterfly, bee different, trends variation them similar streams. Bees found be more closely correlated with native flowering plants zone, rather than cultivated vegetation. Conclusions rivers plays an important role conservation by serving corridor. This provides data supporting protection remaining patches restoration damaged habitats city. survey accumulated on rivers.
