Widespread evolution of poricidal flowers: a striking example of morphological convergence across flowering plants Open
The evolution of tube-like floral morphologies that control pollen release via small openings (functionally poricidal flowers) represents a taxonomically and geographically widespread instance of repeated and independent evolution of a fun…

Transformer Models improve the acoustic recognition of buzz-pollinating bee species Open
Buzz-pollinated crops, such as tomatoes, potatoes, kiwifruit, and blueberries, are among the highest-yielding agricultural products. The flowers of these cultivated plants are characterized by having a specialized flower morphology with po…

Buzzing towards Resilience: Investigating the Spatial Alignment of the Desert Pallid Bee, Centris pallida, and Its Host Plants in Response to Climate Change Open
Wild bees are vital for the pollination of native plants and crops, providing essential ecosystem services. Climate change is known to impact biodiversity and species distributions, but insects adapted to desert ecosystems may exhibit uniq…

Buzz-pollination leads to size-dependent associations between bumblebees and Pedicularis flowers Open
An estimated 20,000 angiosperm species conceal pollen inside tubular poricidal anthers or within modified petals. A bee releases pollen by vibrating its thorax and transferring the force through its mandibles while biting the flower. While…

Buzz-world: Global patterns and drivers of buzzing bees and poricidal plants Open
SUMMARY Foraging behavior frequently plays a major role in driving the geographic distribution of animals. Buzzing to extract protein-rich pollen from flowers is a key foraging behavior used by bee species across at least 83 genera (these …

Symbiotic bacteria and fungi proliferate in diapause and may enhance overwintering survival in a solitary bee Open
Host–microbe interactions underlie the development and fitness of many macroorganisms, including bees. Whereas many social bees benefit from vertically transmitted gut bacteria, current data suggests that solitary bees, which comprise the …

Microbial Metamorphosis: Symbiotic bacteria and fungi proliferate during diapause and may enhance overwintering survival in a solitary bee Open
Host-microbe interactions underlie the development and fitness of many macroorganisms including bees. While many social bees benefit from vertically transmitted gut bacteria, solitary bees, which comprise the vast majority of species diver…

Individual variation in male pheromone production in<i>Xylocopa sonorina</i>correlates with size and gland color Open
Sex pheromones are species-specific chemical signals that facilitate the location, identification, and selection of mating partners. These pheromones can vary between individuals, and act as signals of mate quality. Here, we investigate th…

Bee breweries: The unusually fermentative, lactobacilli-dominated brood cell microbiomes of cellophane bees Open
Pathogens and parasites of solitary bees have been studied for decades, but the microbiome as a whole is poorly understood for most taxa. Comparative analyses of microbiome features such as composition, abundance, and specificity, can shed…

Informing policy and practice on insect pollinator declines: Tensions between conservation and animal welfare Open
Climate change, agricultural intensification, and other anthropogenic ecosystem challenges have caused declines in the diversity and abundance of insect pollinators. In response to these declines, entomologists have called for greater atte…

Structural dynamics of real and modelled <i>Solanum</i> stamens: implications for pollen ejection by buzzing bees Open
An estimated 10% of flowering plant species conceal their pollen within tube-like anthers that dehisce through small apical pores (poricidal anthers). Bees extract pollen from poricidal anthers through a complex motor routine called floral…

Carpenter Bee Thorax Vibration and Force Generation Inform Pollen Release Mechanisms During Floral Buzzing Open
Approximately 10% of flowering plant species conceal their pollen within tube-like poricidal anthers. Bees extract pollen from poricidal anthers via floral buzzing, a behavior during which they apply cyclic forces by biting the anther and …

Does body size predict the buzz‐pollination frequencies used by bees? Open
Body size is an important trait linking pollinators and plants. Morphological matching between pollinators and plants is thought to reinforce pollinator fidelity, as the correct fit ensures that both parties benefit from the interaction. W…

Brawls Bring Buzz: Male Size Influences Competition and Courtship in Diadasia rinconis (Hymenoptera: Apidae) Open
Sexual selection on male body size in species with a female-biased sexual size dimorphism is common yet often poorly understood. In particular, in the majority of bee species, the relative contribution of intrasexual competition and female…
