Abstract: Different mechanisms have been proposed for encoding information into vocalizations: variation of frequency or temporal characteristics, variation in the rate of vocalization production, and use of different vocalization types. We analyze the effect of rate… read more here.

Abstract: Among mammals, only bats and toothed whales are known to produce > 160 calls per second, which occurs shortly before these echolocators capture their prey. This high call rate phase, dubbed terminal buzz, is powered by rare… read more here.
