Sugar Metabolism in Hummingbirds and Nectar Bats
Hummingbirds and nectar bats coevolved with the plants they visit to feed on floral nectars rich in sugars. The extremely high metabolic costs imposed by small size and hovering flight in combination with reliance upon sugars as their main source of dietary calories resulted in convergent evolution of a suite of structural and functional traits. These allow high rates of aerobic energy metaboli...
متن کاملNectar Availability and Parasitoid Sugar Feeding
Habitat diversification can potentially benefit natural enemies by providing alternative prey, a suitable microclimate, or nectar and pollen (Landis et al., 2000). Laboratory and field cage studies demonstrate that parasitoids with access to sugar have greater longevity, fecundity, and more femalebiased sex ratios than starved parasitoids (Idris and Grafius, 1995; Dyer and Landis, 1996; Berndt ...
متن کاملNectar Sugar Production across Floral Phases in the Gynodioecious Protandrous Plant Geranium sylvaticum
Many zoophilous plants attract their pollinators by offering nectar as a reward. In gynodioecious plants (i.e. populations are composed of female and hermaphrodite individuals) nectar production has been repeatedly reported to be larger in hermaphrodite compared to female flowers even though nectar production across the different floral phases in dichogamous plants (i.e. plants with time separa...
متن کاملHoneybees prefer warmer nectar and less viscous nectar, regardless of sugar concentration.
The internal temperature of flowers may be higher than air temperature, and warmer nectar could offer energetic advantages for honeybee thermoregulation, as well as being easier to drink owing to its lower viscosity. We investigated the responses of Apis mellifera scutellata (10 colonies) to warmed 10% w/w sucrose solutions, maintained at 20-35°C, independent of low air temperatures, and to 20%...
متن کاملNectar sugar limits larval growth of solitary bees (Hymenoptera: Megachilidae).
The bottom-up effects of plant food quality and quantity can affect the growth, survival, and reproduction of herbivores. The larvae of solitary bee pollinators, consumers of nectar and pollen, are also herbivores. Although pollen quantity and quality are known to be important for larval growth, little is known about how nectar quality limits solitary bee performance. By adding different levels...
