Floral orientation affects outcross‐pollen deposition in buzz‐pollinated flowers with bilateral symmetry

Lucy Nevard, Mario Vallejo‐Marín

PREMISE: Floral orientation is central to plant-pollinator interactions and is commonly associated with floral symmetry. Bilaterally symmetrical flowers are often oriented horizontally for optimal pollinator positioning and pollen transfer efficiency, while the orientation of radially symmetrical flowers is variable. Buzz-pollinated species (pollinated …

Transmission of bee-like vibrations in buzz-pollinated plants with different stamen architectures

Lucy Nevard, Avery L. Russell, Karl Foord, Mario Vallejo‐Marín

In buzz-pollinated plants, bees apply thoracic vibrations to the flower, causing pollen release from anthers, often through apical pores. Bees grasp one or more anthers with their mandibles, and vibrations are transmitted to this focal anther(s), adjacent anthers, and the whole flower. …

Variation in the natural frequency of stamens in six morphologically diverse, buzz-pollinated, heterantherousSolanumtaxa and its relationship to bee vibrations

Carlos Eduardo Pereira Nunes, Lucy Nevard, Fernando Montealegre‐Z, Mario Vallejo‐Marín

Abstract During buzz pollination, bees use vibrations to remove pollen from flowers. Vibrations at the natural frequency of pollen-carrying stamens are amplified through resonance, resulting in higher amplitude vibrations. Because pollen release depends on vibration amplitude, bees could increase pollen removal by …

Transmission of vibrations in buzz-pollinated plant species with disparate floral morphologies

Lucy Nevard, Avery L. Russell, Karl Foord, Mario Vallejo‐Marín

Abstract In buzz-pollinated plants, bees apply vibrations produced by their thoracic muscles to the flower, causing pollen release from anthers, often through small apical pores. During floral buzzing, bees grasp one or more anthers with their mandibles, and vibrations are transmitted to …

SALMFamide2 and serotonin immunoreactivity in the nervous system of some acoels ( X enacoelomorpha)

Isabel L. Dittmann, Thomas Zauchner, Lucy Nevard, Maximilian J. Telford et autres

Acoel worms are simple, often microscopic animals with direct development, a multiciliated epidermis, a statocyst, and a digestive parenchyma instead of a gut epithelium. Morphological characters of acoels have been notoriously difficult to interpret due to their relative scarcity. The nervous system …

Foraging behaviour and niche differentiation in two South Asian bee species

Lucy Nevard

Pollination across the tropics, including in South Asia, is dominated by social bees. I investigated the behaviour of two species: Apis cerana (Eastern honeybee) and Tetragonula iridipennis (Indian stingless bee) which co-exist in the same environment. The behaviour of these pollinators is …
