Species of the day: Passiflora vitifolia (passion flower) found in one of our fragmented forest patches today. One of our research questions is how local extinction of Heliconia will indirectly influence other plant species like this one (via pollinator limitation). This is a favorite of hummingbirds because of its high amounts of sugary nectar… but can it keep hummingbirds coming to the patch even after Heliconia is gone?
