Pollination is an important ecosystem service mostly provided by diversity of pollinating insects and other animals. As in the anthropocene biodiversity crisis with the climate change, pollination systems are experiencing strongly challenged such as pollinator diversity and abundance decline, pollinator health weakness, pollinator-plant network instability as well as the crop-pollinator habitat fragmentation and insuitability. Here we present some research progress conducted from our group in the last decade. As the pollination dependence of Korean agriculture increases, pollination contribute ap. one forth of national agricultural production, and is responsible substantial portion of vitamin and mineral provisioning. Pollinator diversity is declining in various crop systems and network connectivity is decreasing. Still in agricultural landscape, honeybee (Apis spp) is the main pollinator, accounting ap. 70% of bees, and showed the possible resource partitioning between the native, A. cerana and the introduced, A. mellifera. Simulation of crop-pollinating insect distribution suitability showed up and down directional responses, but more on the negative Further research area for better understanding and stabilizing the plant-pollinator system was proposed.
