28 mar 2022 · Using 84 communities of interacting plants and hummingbirds, we simulated patterns in climate-driven extinctions, coextinctions and colonizations under future climate change scenarios.
The ecological co-dependency between plants and hummingbirds is a classic example of a mutualistic interaction: hummingbirds rely on floral nectar to fuel their rapid metabolisms, and more than 7000 plant species rely on hummingbirds for pollination.
The network illustrates interacting hummingbirds (circles) and plants (squares) over two simulation iterations. At the first iteration (t = 1), climate change causes the loss of one...
31 maj 2023 · Theory suggests that species loss can trigger a coextinction cascade within a community, leading to declines in ecosystem function. However, experiments testing this prediction for plant–pollinator interactions remain uncommon. In this study, we simulated the local extinction of a hummingbird-pollinated understory plant, Heliconia tortuosa ...

21 mar 2018 · Here, we use mutualistic plant–hummingbird networks in the Antillean archipelago to ask how species traits and local abiotic and biotic conditions relate to resource specialization and hummingbird vulnerability to plant extinctions.
Plants depend on hummingbirds for pollination, whereas hummingbirds rely on nectar for food. As a step towards understanding coevolution, this review focuses on the macroevolutionary consequences of plant–hummingbird interactions, a relatively underexplored area in the current literature.
