A study led by researchers at the University of Reading finds that hummingbirds help bromeliad plants, including pineapples, diversify faster than other pollinator groups. The team compiles records of which animals pollinate 403 types of bromeliads, a plant family that includes pineapples and comprises more than 3,700 species. The researchers report that about three out of four of the bromeliad types in their dataset are visited by hummingbirds. Comparing evolutionary rates, they conclude that lineages associated with hummingbird pollination split into new species at roughly twice the speed observed for bromeliads pollinated by other animals. The findings also indicate that geographic factors contribute to how these plants diversify over time, working alongside pollinator effects. Overall, the study links hummingbird pollination with increased speciation rates in bromeliads, suggesting that the birds’ interactions with these plants can influence the pace at which new species arise.

- Researchers analyzed pollination data for 403 bromeliad types.
- Bromeliads include pineapples and more than 3,700 species worldwide.
- Three out of four studied bromeliad types are visited by hummingbirds.
- Bromeliads associated with hummingbird pollination speciate about twice as fast as those linked to other pollinators.
- Geographic factors also play a role in bromeliad diversification over time.
Hummingbirds play a crucial role in accelerating the evolution of bromeliads, leading to a faster emergence of new species. This vibrant bird species serves as pollinators for a staggering three out of four studied bromeliad types. Furthermore, geographical factors have contributed significantly to the diversification of these plants over time.
