	abstract = {Many marine invertebrate fisheries are vulnerable to overexploitation and require conservation measures to ensure their sustainability. In recent years, landings of waved whelk <em>Buccinum undatum</em> (Linnaeus, 1758) have fallen considerably along the coasts of the St. Lawrence (Canada), dropping by up to 76\% in some fishing areas. Local overfishing may be explained, in part, by the species{\textquoteright} oviparous reproduction, which limits larval dispersion and population interactions. Using a two year long-term acoustic telemetry study, we tracked 20 individuals to assess their general movement behaviour and potential to disperse within an area. Tagged individuals displayed considerable daily movements (from a mean of 2 to 16 m/h), with no sensible differences between day and night. Both speed and habitat usage potential (HUP) varied among seasons, most likely due to the species{\textquoteright} reproductive cycle: HUP was significantly larger during the breeding season of May (4570 m2) and June (2779 m2) than in the preceding winter months (1046 m2). Although some individuals moved over a considerable depth range, we did not observe seasonality over the bathymetric gradient of the area. Overall, the species{\textquoteright} restricted HUP limits individual dispersal, resulting in very poor connection between neighbouring populations and making <em>B. undatum</em> vulnerable to local overfishing.},

	abstract = {Green sea turtles Chelonia mydas have the ability to hear and produce sounds under water, with some of them potentially involved in social communication. To investigate the potential biological function of these sounds, we used a combination of acoustic, video and multi-sensor recordings of 23 free-ranging juvenile green turtles and we examined the co-occurrences of sounds with behaviours or external events. Our study revealed that most of the sounds were produced when the sea turtles were resting or swimming. However, four sound types were produced in more specific contexts. Long sequences of rumbles were recorded after sunset and mainly during resting. All these rumbles appear to have been produced by several individuals recorded simultaneously, suggesting that rumbles may be used for social interactions. The frequency modulated sound was highly associated with scratching behaviour. The grunt that was produced occasionally when green turtles were vigilant or approaching a conspecific. The long squeak was produced significantly by a small number of individuals in the presence of humans. The grunt and the long squeak may be the first evidence of an alarm or warning signal for intra-specific communication in green turtles. Our results mark a significant milestone in advancing the understanding of sound production in the behavioural ecology of sea turtles. Further experimental investigations (i.e., playback experiments) are now required to test the hypotheses suggested by our findings. Warning signals could be used to prevent sea turtles of a danger and may contribute to their conservation.},
