Oil collecting bees and Byrsonima cydoniifolia A. Juss. (Malpighiaceae) interactions: the prevalence of long-distance cross pollination driving reproductive success

Anais da Academia Brasileira de Ciências, 2014
Oil-collecting bees are the natural pollinators of oil-flower plants, but little is known about the pollination process and the effectiveness of their pollination service to the reproductive success of their host plants.

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Blueberry pollination in southern Brazil and their influence on fruit quality

Revista Brasileira de Fruticultura, 2011
Blueberry (Vaccinium ashei) is a relatively new crop in cultivation under Southern Brazil conditions. The first collection introduced in the area was formed by rabbiteye cultivars which need insect pollinators and also pollinizers.

Interactions between carpenter bees and orchid bees (Hymenoptera: Apidae) in flowers of Bertholletia excelsa Bonpl. (Lecythidaceae) Interações entre abelhas carpinteiras e abelhas das orquídeas (Hymenoptera: Apidae) em flores de Bertholletia excelsa Bonpl. (Lecythidaceae)

Acta Amazonica, 2012
Competition between two species of bees for the same type of floral resource may generate antagonistic behavior between them, especially in cultivated areas where food resources are limited, seasonally and locally.

Foliar herbivory pushes plant individuals towards the periphery of a plant–floral visitor interaction network

Journal of Ecology, Volume 113, Issue 9, Page 2414-2428, September 2025.
The authors demonstrate how the effects of herbivory on a key plant trait can cascade to shape the interactions between individual plants and their flower visitors and how the indirect effects between herbivores and pollinators can modulate the structure of interaction networks in terrestrial ecosystems.

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool

Biotropica, Volume 57, Issue 5, September 2025.
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.
