The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

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

Adaptive evolution can mitigate the negative effects of temperature stress on plant–pollinator interactions

New Phytologist, Volume 249, Issue 1, Page 554-568, January 2026.
Summary Temperature stress negatively affects various aspects of plant fitness, including plant–pollinator interactions, but whether plants can overcome these adverse effects through adaptive evolution is largely unknown. Here, we conducted a six‐generation evolution experiment using fast‐cycling Brassica rapa plants at ambient and elevated ...

American highbush cranberry maintains strong population structure despite naturalization of Eurasian relatives in North America

American Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Premise The proper classification of taxa is often debated, particularly when organisms lack qualitative diagnostic traits. Highbush cranberry taxa (Viburnum spp.) have been the subject of such disputes since their characterization by 18th‐ and 19th‐century botanists. Despite their allopatric distributions—V.

24 million years of pollination interaction between European linden flowers and bumble bees

New Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

Evolution of petal patterning: blooming floral diversity at the microscale

New Phytologist, Volume 247, Issue 6, Page 2538-2556, September 2025.
Summary The flowers of angiosperms are extraordinarily diverse. While most floral variation is visible to the naked eye, this diversity goes beyond the macroscale: Floral organs comprise an underappreciated range of cell types that generate a multitude of patterns across their surfaces and give rise to novel structures.

Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

Journal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator

American Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Premise In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing.

Patterns of within‐ and among‐plant variation in nectar production in the beetle‐pollinated Amianthium muscaetoxicum

American Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Premise Plant interactions with different pollinator species have shaped the evolution of remarkable diverse nectar production, presentation, and composition traits across the angiosperms. These traits can allow plants to manipulate and reward the behaviors of specific pollinators to enhance pollen donation and receipt with some precision. One
