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. Sorry I missed last week. End of term caught up with me.
Female katydids who don’t vocalize are more at risk of predation than vocalizing males: it’s been assumed for a long time that signaling to attract a mate also attracts predators (it’s certainly true in frogs). This study questions that. The authors found that flying female katydids were caught by bat predators far more often than still vocalizing males.
Shipping noise causes stress and therefore impacts immune response in lobsters: another tale for the “animals we don’t think are affected by anthropogenic noise but actually are” file. Lobsters showed decreased immune response when they were exposed to high levels of shipping noise, which has implications for the fishing industry and the health of lobster stocks.
Fun link of the week: those who have been following this blog for a little while know that I’m a big fan of Lord of the Rings and of movie sound design. Well, today marks the release of the last Hobbit Film, The Battle of the Five Armies. In honor of that, the video in this link’s week walks you through the sound design of the films.
