Echo feedback may also provide functional sen- sory abilities in shrews and tenrecs. The discovery of echolocation traces back to Lazzaro Spallanzani's suggestion in 1794 that bats could "see" with their ears. Griffin (1944, 1958) verified this idea much later when he demonstrated that bats ...
mass index (BMI) on the signal frequency (P = 0.02, mixed-effect GLM as above; Additional file1: Fig. S1). We also compared the wingbeat rate of the two groups, since bats are known to adjust emission timing to their wingbeat in order to conserve energy [27,28], but found no...
We trained fourPipistrellus kuhliibats to takeoff from the same position – the roost wall (henceforth: ‘takeoff point’) in a flight box (200 × 50 × 50 cm3) and land on a target (an elevated platform with a 10 × 7 cm2vertical landing plate) at a distance of ...
spectra, leading to perception of a phantom vertically-extended obstacle (gray ellipses) located immediately to the bat’s front. Even a slight deviation of the bat’s location off-center in the chain corridor makes the echoes at the left and right ears different in arrival-times and spectra,...
Bats experiencing accelerations in an echo-free environment exhibited an intact compensation response. Moreover, using on-board GPS tags on free-flying bats in the wild, we demonstrate that the ability to perform Doppler shift compensation response based on internal cues might be ...
We trained five wild-caught bats to land on a spherical target in both silence and when exposed to broad-band noise to decrease echo detectability, while light conditions were manipulated in both spectrum and intensity. We show that during noise exposure, the bats were almost three times more ...
11.The system of claim 1, wherein the data processor:wherein the data processor creates discrete transmittable sound files from the continuous data and analyzes and determines whether a sound detected by the audio detector is indicative of a bat sound. ...
Urbanization is one of the most influential processes on our globe, putting a great number of species under threat. Some species learn to cope with urbanization, and a few even benefit from it, but we are only starting to understand how they do so. In th
and so it could be a fly in the wall listening to this. I also included tips on cutting back drinking, so things like if I opened a full bottle of wine, I would pour a half bottle or half of it into a half empty bottle. To be more mindful of how much I was drink...
the ball gently between them without letting go of their bungees. While everyone still holds hands, “deflate” the balloon by having everyone in the circle move as close together as possible towards the center. Can the “extract molecule” escape easily when all of the “elastomer molecules”...
