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. It’s officially the last Soundbites before the fall term at OSU begins! 

Light and noise pollution from urban developments may affect ecosystemsthe authors did a literature review on studies done on the impacts of light and noise pollution across Australia, and found some glaring and disconcerting gaps in the research. They highlight several effects from light and noise pollution, including stress, changes in foraging, increased predation risk, and reduced reproductive success. They propose that more careful city planning could mitigate the impacts.

Cuttlefish change visual signals in presence of high noise levelsI’m a sucker for cephalopods, and this study is great. Cuttlefish aren’t acoustic animals; in fact, they use complex visual signals to communicate. However, in the presence of anthropogenic noise playback, they changed their color more often than in the absence of noise. This suggests that anthropogenic noise can affect behavior across modalities, and can have an impact on non-acoustic species. Very cool.

Fun link of the weekit’s the first day of school for OSU students on Monday! And granted, as graduate students, that doesn’t really mean much for most of us in ORCAA, since the work doesn’t stop with the end of term. But trust NPR to deliver when I type “sounds of back to school” into Google.
