Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Rarity of monodominance in hyperdiverse Amazonian forests. [PDF]

, 2019
Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence

Relative pollen productivity estimates from India: A step towards quantitative reconstruction of past plant abundance

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Pollen records and models of pollen–vegetation relationships are required to reconstruct past plant abundances during the Holocene to answer specific questions on climate history, human impact, biodiversity, and their interactions. An important parameter for model applications is pollen productivity, estimated as relative pollen productivity ...

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

Functional Ecology, Volume 40, Issue 2, Page 476-485, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,
