Effects of noise on sound localization in male grasshoppers, Chorthippus biguttulus
TLDR
Noise not only weakly impairs males' directional hearing abilities, but strongly affects their abilities to detect and respond to female songs, which probably increases mating costs, because both males and females must expend additional time and energy in mate attraction. Expand
Sound signalling in orthoptera
TLDR
This review considers recent research in physiology and the links with related areas of acoustic work on the Orthoptera, a multidisciplinary area of research with a strong physiological contribution. Expand

TLDR
The circadian rhythm of locomotor activity of the field mouse Mus booduga was studied and single animal phase response curves (PRCs) were constructed for 15-min daylight pulses of 1000 lux intensity to suggest that the waveform and time course of PRC depend on the animals' endogenous period (tau).

The entrainment of the circadian rhythm of locomotor activity was studied in the field mouse Mus booduga in order to examine the relationship between the free-running period (tau) and minimumExpand
