When approaching an overview of the reproduction of the tribe Colletieae (Rhamnaceae), there was a  single piece of information still missing which concerned the reproductive behaviour of the North American genus Adolphia. To fill this gap we studied a Mexican population of A. infesta included in an agricultural landscape.

Rhododendron is a large genus composed of approximately 1000 species that have a center of diversity in the Himalayas.  Little is known about the pollination ecology of Asian rhododendrons. Bird pollination has been proposed for Rhododendron species with large, red, nectar-bearing flowers, such as Rhododendron floccigerum, but no studies have been conducted to determine what species visit these rhododendrons.
We focused our study on one species of Rhododendron with this morphology: R. floccigerum. We sought to identify the species that visit R. floccigerum in their native range in northwestern Yunnan Province, southwestern China through both in-person observations and camera traps.
