Abstract: It has been hypothesized that flowering plants at high elevation could be pollinated by local passerine birds given that low temperature limits insect activity. In particular, species with large flowers are likely to be pollinated… read more here.

Abstract: A biological trait may promote adaptation to particular pollinators, and this may be a major factor governing the variation of pollination systems among angiosperm taxa. For instance, one long-standing hypothesis is that compared with superior… read more here.
