– Hummingbirds can act as mutualists by transporting pollen grains among flowers, but they may also act as vectors of several organisms which could affect the interaction with their plants. The transmission of such antagonists by hummingbirds searching for nectar rewards may end up in sexually transmitted diseases, pollen consumption and depletion of nectar rewards. Therefore, the supposedly ha...

In that paper was collected a series of 108 cases of ruptured aneurysm treated medical...
