Analysed oxygen consumption data from playback experiments

Average spectral levels of acoustic conditions in the experimental tank.

<p>Sound pressure levels of averaged power spectra (FFT spectrum level units normalised to 1 Hz bandwidth, Hann window, FFT size 1024, 50% overlap) of recordings during band-pass filtered additional-noise playbacks (0.1 to 3.0 kHz; NT) and control playbacks (AT) at two tank depths (5 cm above tank floor and 5 cm below water surface) at the location the fish had to be for the visual predatory stimulus to be released. For control playbacks, spectral levels from 30 s recordings were assessed and averaged over all playback tracks and the two tank depths; for additional-noise playbacks, spectral levels over the whole duration of single looped elements were taken, to account for power fluctuations within a recording of sound emitted by a moving ship, and averaged over all playback tracks and the two tank depths. Recordings were made with an omni-directional hydrophone with preamplifier (HTI 96-MIN; manufacturer-calibrated sensitivity −164.3 dB re 1 µPa; frequency range 2–30 000 Hz) and a solid-state recorder (Edirol R09HR, Roland Corporation), at a sampling frequency of 44.1 kHz and a sampling rate of 16 bits; recording levels calibrated against a 1 kHz reference tone of known amplitude. An example of original ship-noise (NN) and ambient-noise recording (AN) of a UK harbour are given for comparison.</p

Speed of response to a visual predatory stimulus.

<p>Minnows showed no significant effect of noise treatment on response latency (A), while sticklebacks responded significantly more quickly during additional-noise playbacks compared to control playbacks (B). Plots of Kaplan-Meier estimate from mixed model Cox proportional hazards regression, with non-responders included as right-censored maximum-latency data. N = two trials to each of 27 minnows and 35 sticklebacks.</p

The Omani clownfish, <i>Amphiprion omanensis,</i> is endemic to the southern coast of Oman.

<p>Adults provide high levels of parental care to their young that hatch with well-developed swimming and sensory capabilities before embarking on a <3 week pelagic larval phase, during which time they may disperse over long distances (>400 km).</p

CO₂ treatment methods and univariate statistical output from Effect of elevated CO₂ and small boat noise on the kinematics of predator–prey interactions

Comparison of the effects of CO₂ pre-treatment (400, 950 µatm) and sound regime (ambient reef, boat) on the kinematics of the interaction between juvenile damselfish prey (Pomacentrus wardi) and dottyback predator (Pseudochromis fuscus). Only those variable with significant effects are shown. Given (in order) are F, p (p < 0.05 in bold) and partial eta-squared (i.e., effect size). Tests were undertaken with 1 and 68df
