Investigating the effects of fire on pollinator‐dependent distyly polymorphism

open access: yesPlant Biology, EarlyView.
While fire causes some morphological changes in pollinator‐dependent distylous flowers, most traits related to attraction, reward, and stigma‐anther reciprocity remain unaffected, ensuring intermorph pollen transfer and maintaining the floral polymorphism.

Bract size affects resource availability and fruit set in a hummingbird‐pollinated plant with distyly polymorphism

open access: yesPlant Biology, EarlyView.
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The

Polinização realizada por abelhas em cultaras de importância econômica no Brasil

open access: yesBoletim de Indústria Animal, 2013
A polinização realizada por abelhas é uma das melhores alternativas para o aumento da produtividade das culturas, além de contribuir na preservação de áreas com vegetação nativa. A carência de polinizadores nativos é um dos fatores que impede o aumento da produtividade em grande parte das culturas agrícolas.

Plant Communities in the Americas Are Highly Bee Dependent Regardless of Biome or Local Bee Diversity

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 8, August 2025.
ABSTRACT Aim All bees depend on angiosperms for survival, while many angiosperms depend on bees for reproduction. However, bee and flowering plant species richness do not peak in the same geographical regions of the world, suggesting that the flora in regions where bees are not as diverse, such as the tropics, may be relatively less bee‐dependent.

Phenotypic, Floristic, and Anthropogenic Drivers of the Pollen Niche of Amazonian Stingless Bees

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
The pollen diversity and composition collected by Amazonian stingless bees depend on their body mass, tree composition, and urbanization. Further, bees have been collecting fewer pollen types since the 1970s. ABSTRACT Stingless bees (Apidae: Meliponini) are major pollinators in the tropics, supporting key ecosystem services.

Tree traits are a stronger predictor of bee traits and species richness than taxonomic diversity

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 281-292, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured and how they respond to the environment. For example, the high tree species diversity within tropical forests can be grouped into a few functional ...
