Zoo soundscape: Daily variation of low‐to‐high‐frequency sounds
Most studies assessing the impact of noises on zoo animal welfare did not measure sound frequencies outside of the human‐hearing range (infrasounds and ultrasounds). Many nonhuman mammals can hear these frequencies, and because loud and variable soundscapes are potentially detrimental for animal welfare, this overlooked aspect of their acoustic environment could have important consequences. This […]

Elephants use a variety of sensory channels in ways both complementary and redundant to achieve this communication, as well as to advertise physiological states, allow […]
