PDF Ch/aniys (Aequipecten) opercularis (Linnaeus) Argopcten frradins (L n They range from 70.6 to0.0 years old. Swimming and displacement events had a similar mean sound intensity (95.0 2.5 dB re 1 Pa vs. 94.5 2.5 dB re 1 Pa, respectively), as did expulsion and closure events (80.5 1.7 dB re 1 Pa vs. 81.5 1.9 dB re 1 Pa, respectively). With regard to nomenclature, the name Argopecten is shown to be a senior synonym of Plagioctenium; the generic name Aequipecten is rejected for American species related to Argopecten gibbus; and it is concluded that the generic name Chlamys, sensu lato, is better applied as the subfamily name Chlamydinae. Exposures to 5 000 cells L-1 and 10 000 cells L-1 A. minutum resulted in similar valve movement patterns as H. triquetra exposure at the same concentrations, but significant differences were obtained between the two algal treatments at 500 000 cells L-1 (Fig 4). A real scallop will have a similar thickness on all sides, whereas an artificial scallop will often be thicker on one side.

Finally, accelerometer data showed that exposure to A. minutum caused changes in the opening amplitude of expulsion compare to exposure of H. triquetra at 500 000 cells L1 (Wilcoxon test, p = 0.03, Fig 4A4).

During the recording sessions, there was no seawater exchange in the tanks in order to avoid additional noise. Copyright: 2016 Coquereau et al.
