The role of insularity: Plants have few ornithophilous traits but are visited by morphologically more distinct hummingbirds in the Caribbean islands

Functional Ecology, Volume 39, Issue 7, Page 1678-1692, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions.

Data from: Florivory and floral larceny by fly larvae decrease nectar availability and hummingbird foraging visits at Heliconia (Heliconiaceae) flowers

, 2016
Insect larvae inhabit the corolla tubes of some Heliconia species (Heliconiaceae). In this study, we present the first evidence of the influence of these larvae on the pollination ecology of Heliconia plants.

Another tool in the toolbox: Aphid‐specific Wolbachia protect against fungal pathogens

Environmental Microbiology, Volume 26, Issue 11, November 2024.
Wolbachia infected more than 80% of Pentalonia aphids sampled across the Hawaiian Islands and other locations. The aphid‐specific M‐supergroup strains of this symbiont protected against a specialist fungal pathogen, Pandora, but not the generalist pathogen Beauveria or the parasitoid Aphidius colemanii.

Macroevolution of the plant–hummingbird pollination system

Biological Reviews, Volume 99, Issue 5, Page 1831-1847, October 2024.
ABSTRACT Plant–hummingbird interactions are considered a classic example of coevolution, a process in which mutually dependent species influence each other's evolution. Plants depend on hummingbirds for pollination, whereas hummingbirds rely on nectar for food.

Pre‐contact and post‐colonial ecological legacies shape Surinamese rainforests

Ecology, Volume 105, Issue 5, May 2024.
Abstract Disturbances in tropical forests can have long‐lasting ecological impacts, but their manifestations (ecological legacies) in modern forests are uncertain. Many Amazonian forests bear the mark of past soil modifications, species enrichments, and fire events, but the trajectories of ecological legacies from the pre‐contact or post‐colonial ...
