On behalf of all the co-authors, we are pleased to announce the publication of the following paper:

High-frequency whistles of Guiana dolphins (Sotalia guianensis) in Guanabara Bay, southeastern Brazil. 
Abstract: Guiana dolphins produce whistles with a higher frequency and less complexity than most other delphinid species. The presentstudy used a recording system with sampling rate of 192 kHz to describe the high-frequency whistles of Sotalia guianensis in Guanabara Bay,Rio de Janeiro. Eleven acoustic parameters (start, end, minimum, maximum, delta, center and peak frequency, duration, and frequency at 1/4, 1/2, and 3/4 duration) were measured for all whistles. Whistles with a fundamental frequency up to 66.7 kHz were reported, thereby expanding the known frequency range of this species.
