Soundbites is a weekly (biweekly, occasionally) feature of the coolest, newest bioacoustics, soundscape, and acoustic research, in bite-size form. Plus other cool stuff having to do with sound. We’re back in the new year (after a holiday break) with all your favorite acoustics news!

Bowheads show increasing song diversity in Beaufort-Chukchi seasin perhaps one of the more hopeful papers to appear in Soundbites, these researchers report 12 separate bowhead song types found in this area, the most to date. What’s more, they attribute the greater variety to population growth!

Noise may affect signal evolution in grasshoppers: I’m loving all these papers coming out about female preference in the face of noise. Here, females of a species of grasshopper showed a change in shape of their preference function when presented with male calls in noise (as opposed to quiet). Since this signal has a sexual selection component, the noise features of a landscape may in part drive signal modification.

Fun link of the week: I give you five minutes of the cutest frog in the world. Listen to its little peeps. It sounds so grumpy. (Seriously, this will cheer you up. It’s great).
