| Research Abstract |
It is supposed that bumblebees which were dominated in the alpine moved between alpine and subalpine/lower forests according to the density of flower resources. Pollination by small bees, e.g. Halictidae and Andrenidae, should be important even for the bumblebee-dependent plants in the alpine plant communities in which activities of bumblebees decreased. Exotic plants disturbed pollination network in lower forest areas. It is suggested that the exotic plants in the subalpine and surrounding forests affected on the network between alpine plants and bees indirectly.
