Abstract S ‐nitrosylation of Cx43 gap junction channels critically regulates communication between smooth muscle cells and endothelial cells. This post‐translational modification also induces the opening undocked hemichannels. However, its specific impact on vasomotor regulation remains unclear. Considering role TRPV4 channel activation in promoting vasodilatation through nitric oxide (NO) production, we investigated direct modulation hemichannels by activation. Using proximity ligation...
Over 50 genera of bees release pollen from flower anthers using thoracic vibrations, a phenomenon known as buzz-pollination. The efficiency this process is directly affected by the mechanical properties buzzes, namely duration, amplitude, and frequency. Nonetheless, although effects former two are well described, role buzz frequency on remains unclear. Furthermore, nearly all existing studies describing vibrational natural buzz-pollination limited to bumblebees (Bombus) carpenter (Xylocopa)...
Over the past decades, increasing environmental temperatures have been identified as one of causes major insect population declines and biodiversity loss. However, it is unclear how these rising affect endoheterothermic insects, like bumblebees, that evolved thermoregulatory capacities to exploit cold temperate habitats. To investigate this, we measured head, thoracic, abdominal temperature bumblebee (Bombus terrestris) workers across a range (24 °C–32 °C) during three distinct behaviors. In...
Bees are typically diurnal but around 1% of described species have nocturnal activity. Nocturnal bees still poorly studied due to bias towards studying insects. However, knowledge concerning their biology and role as crop pollinators has increased. We review the literature on bees’ traits host plants, assess pollination effectiveness this neglected group. visual adaptations cope with low light intensities, floral scents a key sensory cue used find flowers. generally show high flower...
Abstract Crepuscular bees have larger compound eyes, ommatidia and ocelli than diurnal bees. These visual adaptations allow these to forage during twilight. While the sizes of organs are positively correlated with body size in bees, this relationship is as yet unclear crepuscular Here we measured ocellus; eyes; ommatidial density; dorsal, frontal ventral facets 11 phylogenetically related bee species different temporal patterns. We tested whether how each attributes and/or pattern. Except...
