Optimal concentrations in nectar feeding
WebAug 5, 2003 · 1 . Specialised nectar-feeding birds tend to prefer sucrose over glucose-fructose mixtures or to be indifferent when tested at concentrations close to 584 mmol L −1 sucrose equivalents. The role of the potential interaction between sugar composition and concentration on the sugar preferences of these birds, however, has not been explored. WebDec 7, 2024 · The range of theoretically optimal concentrations found rationalizes the nectar concentration (35%) of flowers pollinated by honey bees in nature, providing a possible mechanistic explanation for the bees' preferred nectar concentration. ...

WebAs sucrose concentration increased, the volume of solution ingested per meal first increased and then decreased gradually, while sucrose intake was highest at concentrations ≧40%. Females fed more than males at all concentrations >10% while temperature had no significant effect on meal size. WebSep 24, 2024 · Optimal concentrations for nectar drinking are limited by the steep increase in the viscosity of sugar solutions with concentration. However, nectar viscosity is inversely related to temperature, which suggests there are advantages to foraging from flowers that are warmer than the surrounding air.
WebMar 1, 2015 · From the formula of nectar intake mass listed above, we can speculate that if all of the hairs erect vertically, namely α ( x )=90°, the proboscis will ideally lift the largest amount of nectar, which can be calculated as . However, the average erection angle was 37.26°, which was not in accordance with the optimal erection angles.
WebDec 7, 2015 · Nectar-intake movements consist of rapid protraction and retraction of glossa from a tube formed by the maxillae and labial palps. We establish a physical model to reveal the driving mechanism of hair erection. Results indicate that the glossa of honeybees is similar to a compression spring. cts v torque converter in silveradoWebMar 20, 2011 · We identify three nectar drinking techniques: active suction, capillary suction, and viscous dipping.
