...). Bending primarily occurred in the portion of the flagellum near the obstacle contact, reducing the length of the flagellum that participated in the oscillating behavior (natural frequency ∼11 Hz). Forced sinusoidal vibrations generated a resonance frequency of ∼30 Hz with imperceptible movement...

...Carol I. Miles; Brianna E. Allison; Michael J. Losinger; Quang T. Su; Ronald N. Miles ABSTRACT This study is a physiological, anatomical and biophysical analysis of how plant-borne vibrational signals are produced by the treehopper Umbonia crassicornis . During courtship, males and females engage...

... in enabling male–female co-localization. If a calling male sits on a vibrationally isolated substrate from the female, such as another disconnected tree, her tremulation signals are not likely to reach him. Tremulation is therefore an insufficient cue in some circumstances, and despite being delayed...

...Felix A. Hager; Wolfgang H. Kirchner Although several behavioural studies demonstrate the ability of insects to localise the source of vibrations, it is still unclear how insects are able to perceive directional information from vibratory signals on solid substrates, because time-of-arrival...

...Ilya A. Volodin; Alexandra S. Zaytseva; Olga G. Ilchenko; Elena V. Volodina; Anastasia L. Chebotareva SUMMARY Self-produced seismic vibrations have been found for some subterranean rodents but have not been reported for any Insectivora species, although seismic sensitivity has been confirmed...

...Emmanuel de Langre Summary The modeling of fluid–structure interactions, such as flow-induced vibrations, is a well-developed field of mechanical engineering. Many methods exist, and it seems natural to apply them to model the behavior of plants, and potentially other cantilever-like biological...

... entails risk. Red-eyed treefrogs have arboreal eggs and aquatic tadpoles. The embryos use vibrations in snake attacks to cue behaviorally mediated premature hatching, and escape, but vibrations from benign sources rarely induce hatching. Missed cues and false alarms are costly; embryos that fail to hatch...

...U. B. Willi; G. N. Bronner; P. M. Narins SUMMARY The hypertrophied malleus in the middle ear of some golden moles has been assumed to be an adaptation for sensing substrate vibrations by inertial bone conduction, but this has never been conclusively demonstrated. The Cape golden mole (Chrysochloris...

...Heidi Pye Henninger; Winsor H. Watson, III SUMMARY American lobsters produce carapace vibrations, which also lead to waterborne acoustic signals, by simultaneously contracting the antagonistic remotor and promotor muscles located at the base of the second antenna. These vibrations have a mean...

... not systematically test such effects, but they are likely to be less pronounced in our system as desert leaf litter is thoroughly desiccated and leaves were uniformly stiff. In general, previous studies of vibrations in leaves on plants show similar all-pass filtering properties(Barth, 2002 ; Magal et al., 2000...

...James C. Nieh; Jürgen Tautz ABSTRACT Waggle-dancing honeybees produce vibratory movements that may facilitate communication by indicating the location of the waggle dancer. However, an important component of these vibrations has never been previously detected in the comb. We developed a method...

... antennal anatomy served as a sound-receiving structure. In the present study, the sound-induced vibrations of the antennal flagellum in male and female Aedes aegypti were compared, and the functional significance of the flagellar hairs for audition was examined. In both males and females, the antennae...

Extracellular recordings from the leg nerve reveal sensitive responses to vibrational stimuli (at a threshold comparable to that found in other tettigoniids) only, and not to airborne sounds. The two possibilities either that this animal shows a secondary reduction...
