- Flying high: limits to flight performance by sparrows on the Qinghai-Tibet Plateau
Summary: Intraspecific differences in flight-related morphological and physiological variables over an ∼3000 m elevational range indicate aerodynamic constraints on flight performance in parallel with enhanced heart and lung masses to offset hypoxic challenge.
- Intracellular regulation of the insect chemoreceptor complex impacts odour localization in flying insects
Summary: The unique signal transduction of the OR complex contributes to insects’ sensitive and efficient olfactory capabilities, supporting the hypothesis that insects evolved a unique chemoreceptor family to accommodate the high-speed demands of flight.
- Echolocation behavior in big brown bats is not impaired after intense broadband noise exposures
Summary: Intense broadband noise exposure does not affect echolocation behavior of big brown bats flying in dense acoustic clutter.
- Differences in spectral selectivity between stages of visually guided mating approaches in a buprestid beetle
Summary: The stereotypical visually guided mating approaches of male buprestid beetles include two stages that use different spectral cues.
- The roles of visual parallax and edge attraction in the foraging behaviour of the butterfly Papilio xuthus
Summary: Freely flying butterflies use motion cues to estimate the proximity of targets.
