... for migration. Here, we examined the energetic cost and flight speed of the long-distance migratory Nathusius’ bat ( Pipistrellus nathusii ). We measured flight metabolism in relation to airspeed in a wind tunnel, inferred the optimal traveling speed over long distances, i.e. maximum range speed, and compared...

... aerodynamic model for minimum power speed, but differed for maximum range speed. The results of our experiment support the theoretical expectation of a U-shaped power curve for flight metabolism in a bat. * Author for correspondence ( [email protected] ) AUTHOR CONTRIBUTIONS R.v.B., S.M.S...

... nectar foragers). Thorax temperatures ranked pollen > nectar > water foragers,and higher flight metabolic rate could explain the higher thorax temperature of pollen foragers. Load mass did not affect hovering metabolic rate or wingbeat frequency in a regression-model experiment. However, using...

... their wingbeat frequency when patrolling. Presumably as a result of these behavioral changes, heat production, and thus inferred flight metabolic rate, is inversely proportional to T a . This is the first demonstration based on field data that an insect regulates body temperature while flying by altering heat...
