Landscape effects on pollinator community and pollination service along a rural-urban gradient in Bengaluru
M Soubadra Devy
Our previous study revealed that urban areas could support a good diversity of pollinators although bee abundance was higher in areas with more natural vegetation. Of interest to us is how urban areas sustain these pollinators. Given that pollination service is sensitive to immediate surroundings and management practices within, we explore how proximity and connectivity between pollinator-supporting patches help shape pollinator communities. In order to explain why certain bees are present in greater numbers in urban landscapes compared to rural areas, we propose to study their responses to changes associated with urbanisation, keeping in mind their life-history traits and dispersal abilities.
We identified green spaces of varying sizes in Bengaluru and sampled bees using pan traps. The results of the study will facilitate the planning of urban green spaces with respect to pollinator diversity and abundance and thus help maintain livelihood and food security.
