This work, conducted in 2013 , is a first monitoring of marine invasive species in Saint-Pierre and Miquelon archipelago. In global changing context on coastal ecosystems , accentuated by direct or indirect effects of human activities, it became essential to implement a survey on marine invasive species on Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors implemented on different stations as well as the timely completion of observational dives , have established the following conclusions : several non native species were detected within the local marine ecosystem. This species , such as Carcinus maenas , Ciona intestinalis , Botryllus schlosseri , Caprella mutica , etc. ... threaten some local marine ecosystems and some local...

Saint-Pierre and Miquelon (SPM) is a small archipelago where instrumental measures based on water column velocity and temperature profiles compiled comprehensive evidence for strong near-diurnal (25.8h) current and bottom temperature oscillations (up to 11.5 °C) which is possibly the largest ever observed — at any frequency — on a stratified mid-latitude continental shelf. The main objective of our study was to identify if Placopecten magellanicus can record on its shell these high frequency environmental variations. To this end, we have tried to identify proxies for water temperature and food availability through development of a new ultra-high resolution LA-ICPMS analyses method capable of resolving shell surface elemental composition with a 10 μm...

Initiated in 2013, the present work carried out in 2014 extends the monitoring network focusing on marine invasive exotic species in Saint-Pierre and Miquelon archipelago. In a global context of coastal ecosystems’ changes, accentuated by direct or indirect effects of human activities, it became essential to implement a monitoring survey and to track the expansion of marine invasive species along Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors deployed on different stations as well as the timely completion of observational dives, have provided the following conclusions: several invasive species were again reported within the local marine ecosystem. Those species, i.e., Carcinus maenas, Caprella mutica, Ciona intestinalis,...
